[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following embodiments and the accompanying drawings specifically illustrate a life test device for the ice-breaking function of an electric suction door lock of the present invention.

[0037] In this embodiment, the life test device 100 for the electric suction door lock ice-breaking function is used to detect the durability of the electric suction side door lock ice-breaking function.

[0038] like Figure 1 , Figure 2 , Figure 3 As shown, the life test device 100 for the ice-breaking function of an electric suction door lock includes: a bracket 10, a door lock mounting component 20, a sliding unit 30, a load unit 40 and a driving unit.

[0039] The bracket 10 includes a bottom plate 11, a first bracket 12, a second bracket 13 and a third bracket 14. The first bracket 12, the second bracket 13 and the third bracket 14 are fixed on the bottom plate 11.

[0040] The door lock mounting member 20 is mounted on the bottom plate 11 and is used to mount the door lock. The door lock mounting member 20 is provided with a first groove 21, and the depth direction of the first groove 21 is parallel to the bottom plate 11. When the door lock is mounted on the door lock mounting member 20, the lock tongue 200 of the door lock is in a fully open state. When the lock tongue 200 is in a fully open state, the depth direction of the groove at the half-locked position of the lock tongue 200 is the same as the depth direction of the first groove 21, and they overlap in the vertical direction.

[0041] like Figure 4 As shown, the sliding unit 30 includes: a slide rail 31, a slider 32 and a lock 33. The slide rail 31 is installed on the bottom plate 11, and the slide rail 31 is parallel to the depth direction of the first groove 21 and corresponds to the first groove 21. The slider 32 is slidably installed on the slide rail 31. The lock is fixed on the slider 32. The slider 32 slides on the slide rail 31, and when the lock tongue 200 is in a fully open state, the lock 33 can move into the groove of the half-locked position of the lock tongue 200 and push the lock tongue 200 to fully lock.

[0042] In this embodiment, the slider 32 includes: a first slider 321 and a lock mounting block 322. The first slider 321 is slidably mounted on the slide rail 31, the lock mounting block 322 is fixed on the first slider 321, and the lock 33 is mounted on the lock mounting block 322.

[0043] The load unit 40 is used to provide a load that simulates the freezing effect of the door lock after the door lock is fully locked. The first bracket 12 and the second bracket 13 are respectively located on both sides of the sliding direction of the slider 32. The load unit 40 includes: a first elastic unit 41 and a second elastic unit 42. One end of the first elastic unit 41 is rotatably mounted on the first bracket 12, the other end of the first elastic unit 41 is rotatably connected to one end of the second elastic unit 42, and the other end of the second elastic unit 42 is rotatably mounted on the second bracket 13. The connecting ends of the first elastic unit 41 and the second elastic unit 42 are mounted on the slider 32. The first elastic unit 41 and the second elastic unit 42 are always in a compressed stress state. The slider 32 slides on the slide rail 31 to drive the connecting ends of the first elastic unit 41 and the second elastic unit 42 to slide, and when the connecting ends of the first elastic unit 41 and the second elastic unit 42 slide, the connecting ends of the first elastic unit 41 and the second elastic unit 42 rotate relative to each other.

[0044] When the forces generated by the first elastic unit 41 and the second elastic unit 42 are both perpendicular to the slide rail 31, the door lock is in a fully open state, the compression forces on the first elastic unit 41 and the second elastic unit 42 are maximum, and the resultant forces generated by the first elastic unit 41 and the second elastic unit 42 in the sliding direction of the slider 32 are zero, that is, Figure 2 , the resultant force of the first elastic unit 41 and the second elastic unit 42 in the left or right direction is zero. Specifically, when the forces generated by the first elastic unit 41 and the second elastic unit 42 are both perpendicular to the slide rail 31, the directions of the forces generated by the first elastic unit 41 and the second elastic unit 42 are parallel to the bottom plate, and the forces generated by the first elastic unit 41 and the second elastic unit 42 are collinear. More specifically, the resultant force generated by the first elastic unit 41 and the second elastic unit 42 is zero. When the lock catch 33 slides toward the door lock direction until the door lock is in a fully locked state, the load force provided by the first elastic unit 41 and the second elastic unit 42 to the door lock meets the force requirement when the door lock is frozen.

[0045] In this embodiment, the ice-breaking function life test device 100 for the electric suction door lock further includes a limiting member 60 mounted on the third bracket 14, and the limiting member 60 is used to limit the maximum distance that the lock catch 33 slides in the door lock direction. Figure 2 As shown, the limiting member 60 is used to limit the maximum distance that the lock buckle 33 slides to the left.

[0046] In this embodiment, if Figure 4 , Figure 5 As shown, the first elastic unit 41 includes a first component 411 , a second component 412 and a first elastic component 413 .

[0047] like Figure 6 As shown, one end of the first component 411 is rotatably mounted on the first bracket 12, and the other end of the first component 411 is a first mounting shaft. One end of the second component 412 is a second mounting shaft, and the second mounting shaft end of the second component 412 corresponds to the first mounting shaft end of the first component 411. The first elastic component 413 is sandwiched between the first component 411 and the second component 412, and the first elastic component 413 is sleeved on the first mounting shaft of the first component 411 and the second mounting shaft of the second component 412, and the first elastic component 413 is always in a compressed force state between the first component 411 and the second component 412. The non-mounting shaft end ( Figure 5When the right end (as shown in the figure) slides in the direction of the slide rail, the distance between the first mounting axis end of the first component 411 and the second mounting axis end of the second component 412 will change, so that the compressive elastic force of the first elastic component 413 will change. When the central axis of the first mounting axis of the first component 411 and the central axis of the second mounting axis of the second component 412 are perpendicular to the slide rail 31, the elastic compression force of the first elastic component 413 is the largest, and no component force is generated along the direction of the slide rail.

[0048] like Figure 4 , Figure 5 As shown, the second elastic unit 42 includes a third member 421 , a fourth member 422 and a second elastic member 423 .

[0049] One end of the third member 421 is rotatably mounted on the second bracket 13, and the other end of the third member 421 is the third mounting axis. One end of the fourth member 422 is the fourth mounting axis, and the fourth mounting axis end of the fourth member 422 corresponds to the third mounting axis end of the third member 421. The second elastic member 423 is sandwiched between the third member 421 and the fourth member 422, and the second elastic member 423 is sleeved on the third mounting axis of the third member 421 and the fourth mounting axis of the fourth member 422, and the second elastic member 423 is always in a compressed stress state between the third member 421 and the fourth member 422. The second member 412 is rotatably mounted between the non-second mounting axis end and the non-fourth mounting axis end of the fourth member 422, that is, Figure 5 From the perspective of the second direction, the right end of the second member 412 is rotatably connected to the left end of the fourth member 422. Figure 5 When the left end of the third component 421 slides in the direction of the slide rail, the distance between the third mounting axis end of the third component 421 and the fourth mounting axis end of the fourth component 422 will change, so that the compressive elastic force of the second elastic component 423 will change. When the central axis of the third mounting axis of the third component 421 and the central axis of the fourth mounting axis of the fourth component 422 are perpendicular to the slide rail 31, the elastic compression force of the second elastic component 423 is the largest, and no component force is generated along the direction of the slide rail.

[0050] Specifically, when the first elastic member 413 and the second elastic member 423 are subjected to the maximum compression force, the first elastic member 413 and the second elastic member 423 are in a straight line, which is parallel to the bottom plate 11 and perpendicular to the slide rail 31. More specifically, the elastic compression forces generated by the first elastic member 413 and the second elastic member 423 are the same.

[0051] Specifically, the limiting member 60 is provided with a limiting through hole 61, and the length direction of the limiting through hole 61 is parallel to the slide rail 31. Figure 2When viewed from the direction of the door, the position of the leftmost end of the limiting through hole 61 meets the requirement. When the rotating shaft 43 is located at the leftmost end of the limiting through hole 61, the lock tongue 200 of the door lock is pushed to the fully locked position by the lock buckle.

[0052] The second member 412 and the fourth member 422 are located between the limiting member 60 and the slider 32. The rotating mounting end of the second member 412 and the rotating mounting end of the fourth member 422 are rotatably mounted via a rotating shaft 43, one end of the rotating shaft 43 is mounted on the slider 32, and the other end of the rotating shaft 43 is located in the limiting through hole 61. Figure 7 As shown, the cross section of the rotating mounting end of the fourth member 422 is "U" shaped, and a mounting hole is provided between the two plate surfaces of the "U" shape. The rotating mounting end of the second member 412 is a plate-shaped plate that matches the rotating mounting end of the fourth member 422, and a mounting hole is provided on the plate-shaped plate. The rotating shaft 43 rotatably mounts the fourth member 422 and the second member 412 through the mounting holes of the rotating mounting end of the fourth member 422 and the rotating mounting end of the second member 412. The slider 32 slides through the rotating shaft 43 to drive the second member 412 and the fourth member 422 to slide. When the second member 412 and the fourth member 422 slide, the second member 412 and the fourth member 422 both rotate relative to each other around the rotating shaft 43. The limiting through hole 61 limits the maximum distance that the rotating shaft 43 moves in the door lock direction, thereby limiting the maximum distance that the lock catch 33 slides in the door lock direction.

[0053] More specifically, the first elastic member 413 and the second elastic member 423 are both springs. The limiting through hole 61 is a waist-shaped hole.

[0054] The driving unit is mounted on the base plate 11 and is used to drive the slider 32 to slide on the slide rail 31 .

[0055] In this embodiment, the driving unit includes a first cylinder 51, which is mounted on the bottom plate 11 and located on the side of the slider 32 facing away from the door lock mounting member 20. The first cylinder 51 is used to push the slider 32 to move toward the door lock mounting member 20.

[0056] Specifically, the driving unit further includes a second cylinder 52, which is mounted on the bottom plate 11 and is located on the side of the slider 32 facing the door lock mounting member 20. The door lock mounting member 20 is provided with a first through hole 22, which is parallel to the direction of the slide rail 31 and corresponds to the slider 32, and the piston rod of the second cylinder 52 corresponds to the first through hole 22, and the piston rod of the second cylinder 52 can push the slider 32 to slide through the first through hole 22.

[0057] More specifically, Figure 2 From the direction of the limit hole 61, the length of the limit hole 61 is such that after the rotating shaft 43 slides to the rightmost end of the limit hole 61, the next door lock can be successfully installed.

[0058] When working, the rotating shaft 43 is located at the rightmost end of the limiting through hole 61. After the door lock is installed on the door lock installation component 20, when the lock tongue 200 is in the fully open state, the depth direction of the groove of the half-locked position of the lock tongue 200 is the same as the depth direction of the first groove 21, and they overlap in the vertical direction. Figure 2 From the direction of the first cylinder 51, the piston rod is driven to move to the left, pushing the slider 32 to move to the left, the slider 32 drives the lock catch 33 to move to the left, the lock catch 33 enters the groove of the half-locked position of the lock tongue 200 and pushes the lock tongue to lock, when the shaft 43 reaches the leftmost end of the limiting through hole 61, the slider 32 cannot move further to the left, and the lock tongue 200 reaches the fully locked position. Figure 8 As shown, the first elastic unit 41 and the second elastic unit 42 provide a certain load for the lock tongue 200, and the piston rod of the first cylinder 51 retracts. When the slider 32 slides to the left, the slider 32 drives the rotating shaft 43 to move to the left, and the rotating shaft 43 slides from the rightmost end to the leftmost end of the limiting through hole 61, and the first elastic unit 41 and the second elastic unit 42 change from a small self-compression force to a maximum self-compression force, and then to a reduced self-compression force.

[0059] When unlocking, Figure 8 As shown, the door lock cannot be opened due to the load and needs to perform the ice-breaking function. The door lock suction motor drives the lock tongue 200 to open, and the lock tongue 200 pushes the lock buckle 33 to move to the right. When the first elastic unit 41 and the second elastic unit 42 reach their maximum compression force, that is, when the combined force generated by the first elastic unit 41 and the second elastic unit 42 in the sliding direction of the slider 32 is zero, the lock tongue 200 is fully opened.

[0060] Door lock replacement process: After the lock tongue 200 is fully opened, if the door lock needs to be replaced, the second cylinder 52 drives the piston rod to move to the right, pushing the slider 32 to continue to move to the right to the rightmost end of the limiting through hole 61, and then the piston rod of the second cylinder 52 retracts and replaces the new door lock.

[0061] The above-mentioned embodiments are preferred examples of the present invention and are not intended to limit the protection scope of the present invention.
