Description
Technical Field
[0001] This utility model relates to the technical field of measuring tools for new energy vehicle lock plate assembly, specifically a measuring tool for new energy vehicle lock plate assembly. Background Technology
[0002] In the manufacturing and maintenance of new energy vehicles, the lock plate is the core component of the door lock system. Its assembly accuracy directly affects the security and reliability of the door lock. Therefore, accurate measurement of the lock plate's size parameters and assembly position is the key to ensuring the performance of the lock system.
[0003] However, existing lock plate measuring tools have significant limitations: First, they lack versatility. Different lock types require different tools depending on the car models they are designed for, leading to high costs from repeated purchases and heavy carrying burdens, a problem exacerbated by rapid model iterations. Second, they are not replaceable. Traditional tools are mostly welded fixed structures; damaged parts require complete scrapping, wasting resources and increasing costs, contradicting the industry's "sustainable and low-cost" philosophy. Third, they have significant operational limitations. The single force application point design makes them prone to efficiency and accuracy issues due to space constraints when dealing with complex lock body layouts, and they are difficult to adapt to new structures such as concealed door handles.
[0004] These problems limit the efficiency of lock plate assembly and maintenance. Therefore, there is an urgent need to develop new measurement tools with high versatility, replaceability and multiple operating points to overcome the limitations of existing technology and meet the diverse needs of lock plate measurement in new energy vehicles. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a measuring tool for assembling lock plates in new energy vehicles.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a measuring tool for assembling lock plates for new energy vehicles, comprising: a measuring tool body, the measuring tool body including a front key, a fixing hole arranged below the front key, and snap-fit holes arranged on both sides of the front key, and a drive piece rotatably snapped onto both ends of the front key through the snap-fit holes, and a connecting hole is also provided at both ends below the front key.
[0007] A fixing plate is arranged below the front key, and four sets of threaded holes are arranged on the fixing plate, the threaded holes being positioned corresponding to the connecting holes.
[0008] As a further description of the above technical solution:
[0009] The two sets of threaded holes on the top of the fixing plate are connected to the connecting holes by fixing screws. All four sets of threaded holes on the top of the fixing plate can be threaded to drive rods for moving the main body of the measuring tool.
[0010] As a further description of the above technical solution:
[0011] The two sets of threaded holes below the fixing plate are connected to scale plate one or scale plate two by fixing screws. Scale plate one and scale plate two are fixedly arranged with scale values for observing size. Scale plate one and scale plate two are used to measure different car locks.
[0012] As a further description of the above technical solution:
[0013] The front-end key has a long pin assembly inside, and the long pin assembly includes:
[0014] Long needle one and long needle two are provided, and a snap-fit block is fixedly arranged on long needle one and long needle two. The snap-fit block snaps into the inside of the fixing hole to fix long needle one and long needle two.
[0015] As a further description of the above technical solution:
[0016] The long needle assembly can also be replaced by two different forms: a medium needle assembly and a short needle assembly. The medium needle assembly is an irregular strip shape, one of which has bent branches. The short needle assembly is a strip shape, and the other is Y-shaped to adapt to different car locks.
[0017] As a further description of the above technical solution:
[0018] The front key has a connection port one and a connection port two on both sides, and the connection port one and the connection port two are engaged with the two sides of the driving plate for connecting the driving plate. Both the driving plate and the driving rod are used to move the main body of the measuring tool, and either one can be selected.
[0019] As a further description of the above technical solution:
[0020] Both long needle one and long needle two have a pointer at one end. When the key is inserted into the lock, the internal parts of the lock press against the top of long needle one and long needle two, thereby moving the pointer to read the value.
[0021] This utility model has the following beneficial effects:
[0022] 1. The front key rotates and connects to the drive plate through the snap-fit hole. With the replacement long needle, medium needle and short needle components, it can accurately match the lock plate measurement needs of various car models.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Example 1:
[0035] like Figures 1 to 8 As shown, this embodiment provides a new energy vehicle lock plate assembly measuring tool, including: a measuring tool body 1, the measuring tool body 1 including a front key 2, and a fixing hole 22 arranged below the front key 2, and snap-fit holes arranged on both sides of the front key 2, and a drive piece 21 is rotatably snapped to both ends of the front key 2 through the snap-fit holes, and a connecting hole is also provided at both ends of the lower part of the front key 2.
[0036] A fixing plate 5 is arranged below the front key 2, and four sets of threaded holes 51 are arranged on the fixing plate 5, the threaded holes 51 corresponding to the positions of the connecting holes 23.
[0037] Understandable, Figure 1 The subject matter is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1 The limitations mean that the topics can also include those that are more... Figure 1 More or fewer parts.
[0038] In this embodiment, the front key 2 is inserted into the locking plate for positioning, and the fixing plate 5 is fixed to the front key 2 by a threaded connection, which drives the plate 21 to rotate on 24 and 25, which is used to move the angle of the measuring tool body 1 to lock the vehicle.
[0039] Specifically, the two sets of threaded holes 51 on the upper part of the fixing plate 5 are connected to the connecting hole 23 by the fixing screw 4. All four sets of threaded holes 51 on the upper part of the fixing plate 5 can be threaded to drive the rod 3 for moving the measuring tool body 1.
[0040] In this embodiment, the fixing screw 4 ensures that the component is fastened. After the driving rod 3 is connected to any set of threaded holes 51 through the thread, it pushes the driving rod 3 to move the measuring tool body 1, thereby measuring the car lock and meeting the measurement of different sizes.
[0041] Specifically, the two sets of threaded holes 51 below the fixing plate 5 are threadedly connected to the scale plate 6 or the scale plate 7 by the fixing screw 4. The scale plate 6 and the scale plate 7 are fixedly arranged with scale values 61 for observing the size. The scale plate 6 and the scale plate 7 are used to measure different car locks.
[0042] As a preferred implementation, the scale plate 6 is fixed to the fixing plate 5 by the fixing screw 4, and the measurement size is displayed by the scale value 61. The scale plate 6 and the scale plate 7 are used to adapt to different car locks, and the size can be observed intuitively.
[0043] Specifically, the front key 2 is provided with a long needle assembly 8 inside, and the long needle assembly 8 includes a long needle one 81 and a long needle two 82, and a snap-fit block 83 is fixedly arranged on the long needle one 81 and the long needle two 82. The snap-fit block 83 is snapped into the inside of the fixing hole 22 to fix the long needle one 81 and the long needle two 82.
[0044] It should be noted that the snap-fit block 83 snaps into the inside of the fixing hole 22 to fix the first long pin 81 and the second long pin 82, thereby achieving stable installation of the long pin assembly 8.
[0045] Specifically, the long needle assembly 8 can also be replaced by two different forms: the medium needle assembly 9 and the short needle assembly 10. The medium needle assembly 9 is an irregular strip shape, one of which has a bent branch shape. The short needle assembly 10 is a strip shape, and the other is Y-shaped, which is used to adapt to different car locks.
[0046] As a preferred implementation, different long pin components can be replaced according to the lock structure. Both the medium pin component 9 and the short pin component 10 have the same parts as the long pin component 8, which can be adapted to different lock structures and expand the scope of application.
[0047] Specifically, the front key 2 has a first connection port 24 and a second connection port 25 arranged on both sides, and the first connection port 24 and the second connection port 25 are engaged with the two sides of the driving plate 21 for connecting the driving plate 21. The driving plate 21 and the driving rod 3 are both used to move the measuring tool body 1, and either one can be selected.
[0048] It should be noted that the connecting port is fixed to the drive plate 21, and the drive plate 21 or the drive rod 3 is driven by force to move the measuring tool body 1, providing two movement methods for easy operation;
[0049] One of the four sets of fixing screws 4 can be removed and the driving rod 3 can be threaded onto the threaded hole 51.
[0050] Specifically, each of the long needle 1 81 and long needle 2 82 is equipped with a pointer 84. When the front key 2 is inserted into the lock, the internal parts of the lock press against the top of the long needle 1 81 and long needle 2 82, thereby moving the pointer 84 to read the value.
[0051] It should be noted that the thrust of the internal lock components is transmitted to the long needle, which in turn drives the pointer 84 to indicate the scale value 61. Effect: The measured value is accurately read by moving the pointer 84.
[0052] Select the appropriate pin assembly (long pin, medium pin, or short pin assembly) according to the model of the lock plate to be tested, and fix it in the fixing hole 22 of the front key 2 by means of the snap-fit block 83. Then install the scale plate 1 6 or scale plate 2 7 on the threaded hole 51 of the fixing plate 5 by means of the fixing screw 4, and align it with the connection hole 23 below the front key 2 for fastening.
[0053] When in use, insert the front key 2 into the lock body. The internal parts of the lock press against the top of the long needle assembly 8 or the middle needle assembly 9 and the short needle assembly 10, causing the pointer at the end of the needle to move. After rotation, the pointer moves to the scale plate and aligns with the scale value 61 to read the lock plate parameters.
[0054] If the measuring angle needs to be adjusted, the driving plates on both sides of the front key 2 can be rotated, or the driving rod can be installed to push the tool to move, flexibly adapting to different lock body structures.
[0055] The complete tool kit, with its replaceable needle assembly and scale plate, is adaptable to the lock plate measurement needs of various car models. The fixing screws ensure the stability of each component, reduce measurement errors, and achieve accurate and efficient lock plate parameter detection.
[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
