Description

Two-wheeled electric vehicle lock durability test bench Technical Field

[0001] This utility model relates to the field of testing tooling technology for electric vehicle parts, and in particular to a durability testing bench for a two-wheeled electric vehicle lock. Background Technology

[0002] The lock on a two-wheeled electric vehicle controls the entire circuitry and is a key component for normal riding. Users frequently open and close the lock during use, which places particular emphasis on the wear resistance of the lock's contact terminals. Therefore, durability testing is especially important. By testing the durability of the contact terminals, the stability of long-term use is verified, and the frequent opening and closing scenarios in daily life are simulated to check whether the lock cylinder is stuck and whether the contact is good.

[0003] Current testing of locks for two-wheeled electric vehicles suffers from problems such as incomplete coverage, short testing cycles, insufficient long-term durability data, inadequate material aging simulation, and disconnect from real-world scenarios. As a result, the testing standards vary widely and cannot meet the requirements for frequent opening and closing. Summary of the Invention

[0004] In response to the shortcomings of the existing production technology, the applicant provides a two-wheeled electric vehicle lock durability testing bench, which is suitable for various locks to be tested, and can perform long-term fatigue durability tests on the locks to be tested, providing reliable test results.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A durability testing stand for two-wheeled electric vehicle locks, comprising at least one set of testing fixtures, including:

[0007] The locking bracket is fixedly installed on the test bench and is used to limit the locking mechanism.

[0008] A stand is mounted on the test bench, and a motor is installed on the stand. The motor's output shaft drives a clamping part, which corresponds to a locking bracket and is used to clamp the key head, rotating relative to the locking bracket.

[0009] The motor can move in both the horizontal and vertical directions to adapt to the locking position.

[0010] As a further improvement to the above technical solution:

[0011] The clamping part is coaxially arranged with the motor output shaft, and a groove for accommodating the key head is provided on the end face of the clamping part facing the lock.

[0012] The groove of the clamping part is configured as a through groove, with both ends of the groove extending to the outer wall of the clamping part.

[0013] The inner wall of the groove is provided with an elastic layer, which holds the key head.

[0014] The opening of the groove is wedge-shaped.

[0015] A reference plate is installed at the top of the upright, and a lifting plate is installed on the upright; a lifting structure is installed on the reference plate to drive the lifting plate to reciprocate.

[0016] A cylinder is installed on the lifting plate, and the cylinder drives the motor to reciprocate.

[0017] A slide rail connects the motor and the lifting plate.

[0018] The locking bracket is located on the vertical movement path of the motor.

[0019] The lifting structure is positioned close to the motor's center of gravity.

[0020] The beneficial effects of this utility model are as follows:

[0021] This invention provides two sets of testing fixtures on a testing platform, allowing for simultaneous testing or individual use of one set. During testing, the key head is effectively limited. Since the key head needs to be rotated, the clamping part pushes and rotates the key head's planar position, ensuring smooth rotation under force. Furthermore, the through-groove design allows for the use of key heads of different sizes.

[0022] The durability testing fixture provided in this application can expose design defects in advance through high-frequency opening and closing scenarios, thereby enhancing user trust and brand competitiveness. With the deepening of intelligentization and supervision, the importance of durability testing will be further highlighted. Attached Figure Description

[0029] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0030] As shown in Figures 1-4, the two-wheeled electric vehicle lock durability test bench 1 of this embodiment is equipped with at least one set of test fixtures 2, which include:

[0031] The locking bracket 201 is fixedly installed on the test bench 1 and is used to limit the locking mechanism.

[0032] A support frame 202 is mounted on the test bench 1. A motor 207 is installed on the support frame 202. The output shaft of the motor 207 drives a clamping part 209, which corresponds to a locking bracket 201 and is used to clamp the key head 3, rotating relative to the locking bracket.

[0033] Motor 207 can move in both the horizontal and vertical directions to adapt to the locking position.

[0034] The clamping part 209 is coaxially arranged with the output shaft of the motor 207. On the end face of the clamping part 209 facing the lock, a groove 210 is provided for accommodating the key head 3.

[0035] The groove 210 of the clamping part 209 is configured as a through groove 210, and both ends of the groove 210 extend to the outer wall of the clamping part 209.

[0036] An elastic layer 211 is provided on the inner wall of the groove 210, and the elastic layer 211 clamps the key head 3.

[0037] The opening of groove 210 is wedge-shaped.

[0038] A reference plate 204 is installed on the top of the upright 202, and a lifting plate 203 is installed on the upright 202; a lifting structure is installed on the reference plate 204 to push the lifting plate 203 to reciprocate.

[0039] A cylinder 206 is installed on the lifting plate 203, and the cylinder 206 drives the motor 207 to reciprocate.

[0040] A slide rail 208 connects the motor 207 and the lifting plate 203.

[0041] The locking bracket 201 is located on the vertical movement path of the motor 207.

[0042] The lifting structure is positioned close to the center of gravity of motor 207.

[0043] The specific structure and working principle of this utility model are as follows:

[0044] Example 1

[0045] Figure 1 shows a schematic diagram of the entire machine according to this application. As can be seen in the figure, the test bench 1 is equipped with two sets of test fixtures 2. More sets of test fixtures 2 can also be set on a single test bench 1 according to actual needs.

[0046] The specific structure of test fixture 2 is shown in Figures 2 and 3. The following is an explanation using one set of test fixture 2 as an example.

[0047] A set of test fixtures 2 includes a lock fixing bracket 201 and a key-end power unit. The structure of the lock fixing bracket 201 only needs to be able to fix the lock in a designated position. Figure 2 shows an optional lock fixing bracket 201 structure, which uses a metal sheet bent into shape as a base to elevate the lock; a block with through holes is added to the base, and the lock is fastened to the block. The block is locked onto the base to form a stable limit.

[0048] The key-end power unit is required to have two functions: pushing the clamping part 209 close to the key end and driving the key end to reciprocate. In this embodiment, the key-end power unit is provided with a set of uprights 202, on which a lifting plate 203 is provided, and a reference plate 204 is provided on the top of the uprights 202. The lifting plate 203 reciprocates relative to the reference plate 204. The structure for pushing and lifting can be a lead screw, a screw rod 205, or a cylinder 206. Considering the ease of operation and cost, this application prefers a screw rod 205 with a handle as the power structure for pushing the lifting plate 203.

[0049] A sliding structure is connected below the lifting plate 203. The sliding structure includes a cylinder 206 mounted on the lifting plate 203. The piston rod of the cylinder 206 drives a motor 207. The motor 207 is connected to the lifting plate 203 via a slide rail 208. When the cylinder 206 pushes or pulls the motor 207, the motor 207 can perform forward and backward extension movements. A clamping part 209 is connected to the output shaft of the motor 207 to limit the key end.

[0050] That is, the cylinder 206 of the key end power unit adjusts the vertical coordinate of the motor 207, the cylinder 206 adjusts the horizontal coordinate of the motor 207, and the cylinder 206 rotates itself to provide rotational power to the key end.

[0051] In one embodiment of this application, the clamping part 209 is designed for flat keys, featuring a cylindrical shape and a slotted end face 210. The slot 210 of this clamping part 209 is a recessed groove 210, as shown in Figure 3, which sinks from the cylindrical end and extends through the circumferential surface. The advantage of this slot 210 is that it can limit the position of the key head 3 regardless of its width. If the key head 3 is larger than the diameter of the cylindrical end, it can extend from both sides of the slot 210. Therefore, theoretically, as long as the thickness of the key head 3 is less than the width of the slot 210, the tooling of this application can be used.

[0052] Example 2

[0053] As a preferred embodiment, different keys may have different thicknesses of key head 3. Therefore, this application proposes another implementation that can be applied to more specifications of key head 3.

[0054] As shown in Figure 4, in this embodiment, to accommodate key heads 3 of different thicknesses, an elastic layer 211 is added to the inner wall of the groove 210 on the cylinder. The elastic layer 211 can be made of rubber. When the key head 3 is inserted into the groove 210, the deformation of the elastic layer 211 provides sufficient space for accommodating the key head 3. At the same time, the restoring force of the elastic layer 211 assists in clamping the key head 3, thus helping to limit its movement.

[0055] To facilitate the insertion of the key head 3, the opening of the groove 210 is set in a conical shape as shown in Figure 4.

[0056] Example 3

[0057] Based on Embodiment 2, since the friction between the rubber and the key head 3 is relatively large, the rubber layer can be improved into several rubber strips or several rubber dots. This can both utilize the deformation force of the rubber to resist and limit the key head 3, and at the same time reduce the resistance generated by the friction between the key head 3 and the rubber when it is inserted into the groove 210.

[0058] The aforementioned through slot 210 design has another advantage: since there may be a small error in the longitudinal height of the manually adjusted motor 207, the through slot 210 design has a lower requirement for the relative positional accuracy between the key head 3 and the slot 210. For example, the key head 3 may extend more at one end of the slot 210 and less at the other end, which will not affect the limiting effect.

[0059] When using the tooling of this application for testing, adjust the cylinder 206 according to the required specifications of the lock combination to move the motor 207 back and forth to a suitable position, and then adjust the lifting plate 203 to drive the motor 207 up and down to a suitable position.

[0060] The lock is fixed on the lock fixing bracket 201, and the key end is fixed in the groove 210 of the clamping part 209.

[0061] Turn on the test system switch, observe the operation display screen for any abnormalities, set the relevant parameters, touch the start button, the motor 207 drives the key head 3 to rotate back and forth, the lock body of the lock does not move, and the working durability test begins.

[0062] After the test is completed, observe the relevant data on the operation display screen, save the test record, and turn off the test system switch. If the product fails to meet the requirements or other abnormalities occur during the test, the alarm light will flash and the alarm will sound. In case of emergency, press the emergency stop switch, observe and record the relevant data, and then turn off the test system switch.

[0063] The aforementioned central control and switch can be implemented using existing technology, and will not be elaborated upon in this application. The main advantage of this application is that it provides a long-term testing environment for lock sleeves of different specifications.

[0064] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
