Sliding door limiting block with constant counter force
The invention relates to a sliding door limiting block with constant counterforce. A vehicle door contact part is movably arranged on a vehicle body connecting part; the counter-force constant maintaining part is arranged in the vehicle body connecting part and is connected with the vehicle door contact part through an elastic piece; the counter-force constant maintaining part comprises a force transmission structure and a directional deformation energy absorption structure; the force transmission structure is provided with protrusions in the moving direction, and a groove is formed between every two adjacent protrusions. When the counter force generated when the car door contact part compresses the elastic piece is larger than the maximum energy absorption capacity, the directional deformation energy absorption structure abuts against the multiple protrusions one by one and deforms to absorb energy, so that the counter force is gradually reduced till the car door contact part is locked in the groove, and at the moment, the counter force does not exceed the maximum energy absorption capacity; when the counter force is smaller than or equal to the maximum energy absorption capacity, the directional deformation energy absorption structure is locked in the groove, deforms and absorbs energy when being connected with the protrusion, and resets when being connected with the groove, so that the final output value of the counter force is constant, and the quality problem of the sliding door caused by too large or too small limiting counter force is solved.
本申请涉及一种反力恒定的滑移门限位块，由于车门接触部分移动设置在车身连接部分上；反力恒定维持部分设置在车身连接部分内，并通过弹性件与车门接触部分连接；反力恒定维持部分包括传力结构和定向变形吸能结构；传力结构在移动方向上具有凸起，相邻两个凸起之间形成凹槽；当车门接触部分压缩弹性件产生的反力大于吸能的最大能力时，定向变形吸能结构逐个与多个凸起抵持并变形吸能，以将反力逐步减少，直到锁止在凹槽内，此时反力不超过吸能的最大能力；当反力小于等于吸能的最大能力时，定向变形吸能结构锁止在凹槽内，与凸起连接时变形吸能，与凹槽连接时复位，以使反力最终输出值恒定，解决了限位反力过大或过小带来的滑移门质量问题。
