[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] The following is combined with Figures 1-3 This invention describes a durability testing apparatus for zipper-type door locks.

[0023] like Figure 1As shown, in the embodiment of the present application, the zipper type door lock durability test device comprises a control member 10, an opening and closing mechanism 20 and a base 30. The opening and closing mechanism 20 is arranged on the base 30, and one end of the control member 10 can be engaged with or separated from the opening and closing mechanism 20. The two ends of the opening and closing mechanism 20 are respectively used for connecting with the lock body and the lock core of the door lock, and the opening and closing mechanism 20 has a switchable first state and a second state. When the control member 10 is engaged with the opening and closing mechanism 20, the opening and closing mechanism 20 is in the first state, the lock core is connected with the lock body, and the door lock is in the closed state. When the control member 10 is separated from the opening and closing mechanism 20, the opening and closing mechanism 20 is in the second state, the lock core is separated from the lock body, and the door lock is in the open state.

[0024] Specifically, the opening and closing mechanism 20 has a switchable first state and a second state. When the opening and closing mechanism 20 is in the first state, the opening and closing mechanism 20 is closed, the lock core is connected with the lock body, and the door lock is in the closed state. When the opening and closing mechanism 20 is in the second state, the opening and closing mechanism 20 is open, the lock core is driven to move, so that the lock core is separated from the lock body, and the door lock is in the open state. In this embodiment, the control member 10 is engaged with or separated from the opening and closing mechanism 20, so that the state of the opening and closing mechanism 20 can be switched, and the door lock can be closed or opened for durability test.

[0025] Specifically, one end of the control member 10 can be connected with a robot, or an operator holds one end of the control member 10, and controls the action of the control member 10 to engage or separate the control member 10 with the opening and closing mechanism 20. When the control member 10 is engaged with the opening and closing mechanism 20, the control member 10 applies force to the opening and closing mechanism 20, so that the opening and closing mechanism 20 is in the closed state, and at this time, the door lock is in the closed state. When the control member 10 is separated from the opening and closing mechanism 20, the opening and closing mechanism 20 is in the open state under its own action, and further drives the lock core to move, so that the door lock is in the open state.

[0026] The zipper type door lock durability test device provided by the embodiment of the present application can automatically switch the closing or opening of the door lock by arranging the control member and the opening and closing mechanism. When the control member is engaged with the opening and closing mechanism, the door lock is in the closed state. When the control member is separated from the opening and closing mechanism, the door lock is in the open state. The automatic switching of the closing or opening of the door lock is realized, and the door lock durability test does not need to use the on-board fixed switch, so that the robot travel time is shortened, and the test efficiency is improved.

[0027] As Figure 1As shown, in the embodiment of the present application, the opening and closing mechanism 20 comprises a movable plate 21, a fixed plate 22 and an elastic member 23. The fixed plate 22 is connected with the base 30, the first end of the movable plate 21 is hinged with the base 30, the second end of the movable plate 21 can be overlapped or separated with the control member 10, and the two ends of the elastic member 23 are connected with the fixed plate 22 and the movable plate 21 respectively. The movable plate 21 has a first state and a second state, in the case that the movable plate 21 is in the first state, the second end of the movable plate 21 is close to the fixed plate 22, and in the case that the movable plate 21 is in the second state, the second end of the movable plate 21 is away from the fixed plate 22.

[0028] Specifically, in the embodiment, the fixed plate 22 is fixedly connected with the base 30, the first end of the movable plate 21 is connected with the base 30 through the hinge 24, so that the second end of the movable plate 21 is movable. The fixed plate 22 is used to be connected with the lock body, and the movable plate 21 is used to be connected with the lock cylinder. When the control member 10 is overlapped with the second end of the movable plate 21, the control member 10 exerts force on the movable plate 21, so that the movable plate 21 is in a fixed state, at this time, the lock cylinder is not subjected to tension, the lock cylinder is connected with the lock body, and the door lock is in a closed state. When the control member 10 is separated from the second end of the movable plate 21, the movable plate 21 moves away from the fixed plate 22 under the action of the hinge 24, the movable plate 21 drives the lock cylinder to move, so that the lock cylinder is separated from the lock body, and the door lock is in an open state. In the process that the hinge 24 drives the movable plate 21 to move away from the fixed plate 22, the elastic member 23 is stretched under force. Then, the elastic member 23 is reset, and drives the movable plate 21 to move towards the fixed plate 22 by using elastic force. Finally, under the action of the control member 10, the movable plate 21 is in the first state again, at this time, the lock cylinder is connected with the lock body again, and the door lock is in the closed state again. Through repeated operation, the durability of the door lock can be tested.

[0029] The durability test device for the pull-to-open door lock provided by the embodiment of the present application is provided with the movable plate, the elastic member, the fixed plate and the hinge. After the control member is separated from the movable plate, the hinge drives the movable plate to move away from the fixed plate by using damping force, so as to open the door lock. The elastic member drives the movable plate to move towards the fixed plate by using elastic force, and finally restores to the initial state under the action of the control member, so as to make the door lock in the closed state again. Through controlling the action of the control member, the opening and closing of the door lock is repeatedly switched, the structure of the durability test device for the door lock is simplified, the test process is simple, and the test efficiency is improved.

[0030] In an optional embodiment, according to the damping force of the hinge 24 and the elastic force of the elastic member 23, when the door lock is in the closed state, the movable plate 21 can be overlapped with the fixed plate 22, or there is a certain distance between the movable plate 21 and the fixed plate 22.

[0031] In one specific embodiment, the length of the movable plate 21 is greater than the length of the fixed plate 22, and the movable plate 21 overlaps the fixed plate 22 when the door lock is in the closed state, and the second end of the movable plate 21 extends above the fixed plate 22. In actual operation, when it is desired to have the movable plate 21 in the first state again, the control member 10 only needs to overlap the movable plate 21 and the fixed plate 22 to ensure that the door lock is in the closed state.

[0032] Further, since the fixed plate 22 is connected to the base 30 at only one end, and the free end of the fixed plate 22 bears a certain pressure when the movable plate 21 is in the first state, in order to prevent the fixed plate 22 from shaking, the zip lock door lock durability test device further comprises a reinforcing rib 60 for connecting the fixed plate 22 and the base 30 to improve the firmness of the fixed plate 22 after being connected to the base 30.

[0033] As shown in Figure 2 In the embodiment of the present application, the movable plate 21 is provided with a plurality of first clamping grooves 211 in the first direction, and the plurality of first clamping grooves 211 are arranged in parallel, and a first connecting portion 212 is formed between adjacent two first clamping grooves 211, and the lock cylinder is connected to any first connecting portion 212, wherein the first direction is perpendicular to the base 30.

[0034] Specifically, the movable plate 21 is provided with a plurality of first clamping grooves 211 in the height direction of the movable plate 21, that is, each first clamping groove 211 is arranged in the length direction of the movable plate 21, and one end of each first clamping groove 211 extends to the edge of the movable plate 21, so that the movable plate 21 has a plurality of first connecting portions 212 arranged in parallel. In the test, the fixed plate 22 is connected to the lock body, and the lock cylinder can be connected to different first connecting portions 212. When the lock cylinder is connected to different first connecting portions 212, the movement stroke of the lock cylinder is different.

[0035] Specifically, since the movable plate 21 is in an inclined state when it is in the first state, when it rotates, the movement stroke of each first connecting portion 212 is different, so that when different first connecting portions 212 are connected to the lock cylinder, the lock cylinder with different strokes can be tested for durability.

[0036] As shown in Figure 2 In the embodiment of the present application, the movable plate 21 is further provided with a second clamping groove 213, the extension direction of the second clamping groove 213 is perpendicular to the extension direction of the first clamping groove 211, and the second clamping groove 213 is in communication with the plurality of first clamping grooves 211.

[0037] Specifically, in the present embodiment, the second clamping groove 213 is arranged in the height direction of the movable plate 21, and the second clamping groove 213 is in communication with the plurality of first clamping grooves 211 to form an operation space when the movable plate 21 is connected to the door lock.

[0038] AsFigure 3 As shown, in an embodiment of the present invention, the fixing plate 22 is provided with a plurality of third slots 221 along the first direction. The plurality of third slots 221 are arranged in parallel, and a second connecting part 222 is formed between two adjacent third slots 221. The lock body is connected to any third slot 221.

[0039] Specifically, the fixed plate 22 has multiple third slots 221 along its height direction. Each third slot 221 is opened along the length of the fixed plate 22, with one end extending to the edge of the fixed plate 22. This gives the fixed plate 22 multiple parallel second connecting parts 222. During testing, the lock body can be connected to any of the second connecting parts 222. Because the movable plate 21 is inclined, when the lock cylinder's position remains fixed, the distance between the lock cylinder and the lock body is not the same when the lock body is connected to different second connecting parts 222. This also allows for durability testing of locks with different lock cylinder strokes.

[0040] Furthermore, when the lock cylinder is connected to different first connecting parts 212 and the lock body is connected to different second connecting parts 222, the lock cylinder and the lock body can have various sizes to enable durability testing of door locks with various lock cylinder strokes.

[0041] like Figure 3 As shown, in an embodiment of the present invention, the fixing plate 22 is further provided with a fourth slot 223, the extension direction of the fourth slot 223 is perpendicular to the extension direction of the third slot 221, and the fourth slot 223 is connected to a plurality of third slots 221.

[0042] Specifically, in this embodiment, a fourth slot 223 is provided along the height direction of the fixing plate 22. The fourth slot 223 is connected to multiple third slots 221 to form an operating space when the fixing plate 22 is connected to the door lock.

[0043] like Figure 1 As shown in the embodiment of the present invention, the zipper-type door lock durability testing device further includes a support member 40, which is connected to the base 30. The length of the support member 40 is adjustable so that the zipper-type door lock durability testing device can perform durability tests on door locks of different vehicle models.

[0044] Optionally, the support member 40 can be a pneumatic cylinder or a hydraulic cylinder, or the support member 40 can also be a pair of connecting rods, each of which has multiple holes along its own length. The pair of connecting rods are connected through different holes, which can realize the adjustment of the length of the support member 40.

[0045] like Figure 1As shown, in the embodiment of the present application, the zipper door lock durability test device further comprises a fixing plate 50 connected with the support 40, and the fixing plate 50 is used to be placed on the ground.

[0046] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
