Description

Technical Field

[0001] This invention belongs to the technical field of sheet metal processing equipment, and specifically relates to a body sheet metal damage simulator. Background Technology

[0002] In sheet metal damage repair training, damage simulation is necessary. Traditional damage simulation mostly involves manual hammering of the sheet metal. However, due to the randomness of manual operation, the force and location of each strike are inconsistent, resulting in varying damage areas and degrees. Damage parameters cannot be controlled, and damage varies significantly across different parts, making it difficult to accurately control the repair difficulty during training and affecting the teaching effectiveness. Furthermore, existing hammers can only simulate impact damage and cannot simultaneously simulate scratches caused by collisions during vehicle operation, which also hinders comprehensive and thorough teaching training. Summary of the Invention

[0003] In view of this, in order to solve the problems mentioned in the background art, the purpose of the present invention is to provide a body sheet metal damage simulator.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The impact simulation mechanism includes an impact member, a spring, and an adjusting member assembled within the hollow space. The spring applies an elastic driving force to the impact member along a predetermined impact direction to drive the impact member to generate an impact simulation motion stroke along the impact direction. The impact simulation motion stroke has an energy storage position where the impact member is fully contained within the hollow space and compresses the spring to store energy, and a release position where the impact member at least partially protrudes from the opening to simulate an impact. The adjusting member has an adjusting motion stroke that applies an overcoming force to the spring to intensify the compression of the spring.

[0008] The scratch simulation mechanism includes a guide and a scratching member connected to the main rod, the scratching member having a scratch simulation motion stroke generated by the action of the guide.

[0009] Preferably, the impact simulation mechanism further includes a latch, which has a stop position for blocking and limiting the impact member moving to the energy storage position along the impact direction and an unlock position for releasing the impact member and releasing the blocking and limiting position.

[0011] Preferably, the main rod body includes a long rod body and a short rod body, the hollow part is located in the long rod body, the proximal end of the hollow part is a threaded part connected to the short rod body, so that the short rod body closes the proximal end of the hollow part, the guide is connected to the middle part of the short rod body, and the swivel is connected to the proximal end of the short rod body.

[0012] Preferably, the short rod has a radial circular hole in the middle that allows the guide to pass through, and the guide is a round rod, so that the proximal end of the short rod can swing back and forth around the central axis of the guide, or that the proximal end of the short rod can move back and forth along the axial direction of the guide.

[0013] Preferably, the scrubbing element includes a mounting base connected to the proximal end of the short rod and a scrubbing blade rotatably mounted on the mounting base, the scrubbing blade's rotation axis being perpendicular to the central axis of the short rod.

[0014] Preferably, the mounting base is provided with a connecting screw, and the short rod body is provided with an axial connecting screw hole that mates with the connecting screw.

[0029] Example 1

[0030] like Figure 1 As shown, the present invention provides a vehicle body sheet metal damage simulator, comprising a main rod 1, an impact simulation mechanism 2, and a scratch simulation mechanism 3. Specifically, the main rod 1 has a proximal end and a distal end. The impact simulation mechanism 2 is coupled to the distal end of the main rod 1 to simulate impact damage on the vehicle body sheet metal parts through the distal end of the main rod 1. The scratch simulation mechanism 3 is coupled to the proximal end of the main rod 1 to simulate scratch damage on the vehicle body sheet metal parts through the proximal end of the main rod 1, thereby meeting different training needs.

[0031] In one example, the scratch simulation mechanism 3 includes, as shown below: Figure 1 The guide member 31 and the scratch member 32 are shown and connected to the main rod 1. Specifically, the main rod 1 has a radial circular hole 121 through which the guide member 31 passes. The guide member 31 is a round rod. When the scratch member 32 is guided by the guide member 31 to simulate the scratch movement, the guide member 31 is inserted into the radial circular hole 121. This allows the proximal end of the main rod 1 to drive the scratch member 32 to reciprocate around the central axis of the guide member 31, thereby simulating scratch damage on the body sheet metal based on the relative friction between the scratch member 32 and the body sheet metal. Of course, the main rod 1 can also reciprocate along the axial direction of the guide member 31 under the guidance of the guide member 31, thus similarly simulating scratch damage on the body sheet metal based on the relative friction between the scratch member 32 and the body sheet metal.

[0032] It should be noted that the dividing element 32 specifically includes, as follows: Figure 1 and Figure 4 The mounting base 321 connected to the near end of the main rod 1 and the scrubber 322 rotatably mounted on the mounting base 321 are shown. The axis of rotation of the scrubber 322 is perpendicular to the central axis of the main rod 1, thereby ensuring that when the scrubber 32 moves under the guidance of the guide member 31 to generate a scratch simulation stroke, the scrubber 322 acts on the surface of the body sheet metal, thereby simulating the production of scratch damage based on the sliding of the scrubber 322 blade on the surface of the body sheet metal.

[0033] In another example, the main rod 1 has the following features inside: Figure 2 The hollow 11 shown has an opening 12 at its distal end. The impact simulation mechanism 2 includes an impact member 21 and a spring 22 assembled within the hollow 11. The spring 22 applies an elastic driving force to the impact member 21 along a predetermined impact direction, causing the impact member 21 to generate an impact simulation motion stroke along the impact direction. During this impact simulation motion stroke, there is an energy storage position where the impact member 21 is completely contained within the hollow 11, compressing the spring 22 to store energy, and a release position where the impact member 21 at least partially protrudes from the opening 12 to simulate an impact. Specifically, the impact member 21 is... Figure 2 The impact rod shown is slidably assembled inside the hollow 11 of the main rod body 1. The distal end of the impact rod is provided with an impact head that can pass through the opening 12. Preferably, the diameter of the impact head is smaller than the diameter of the impact rod, so as to ensure that the impact member 21 can effectively perform the impact while preventing the impact member 21 from completely detaching from the hollow 11.

[0034] It should be noted that the impact member 21 is provided with a latch 24, which is a locking rod that radially penetrates the impact member 21. The shell wall of the main rod body 1 is provided with an extension hole 13 that allows the latch 24 to pass through. The extension hole 13 includes, for example, Figure 3 The first extension extending along the axial direction of the main rod 1 and the second extension extending circumferentially along the main rod 1, i.e., the extension hole 13, form an L-shaped structure on the radial projection plane.

[0035] In this embodiment, when the latch 24 is pushed from the distal end to the proximal end of the first extension, the latch 24 drives the impact member 21 from the release position to the energy storage position. Then, by pushing the latch 24, the impact member 21 is rotated, and the latch 24 moves along the second extension, that is, from the unlock position to the stop position. When the latch 24 engages with the second extension of the extension hole 13, it stops and limits the impact member 21, which has moved to the energy storage position, along the impact direction, and completes the compression and storage of the spring 22. Specifically, when performing the impact simulation, the latch 24 is pushed along the second extension from the stop position to the unlock position, thereby releasing the stop and limiting and releasing the impact member 21. The impact member 21 is subjected to the elastic driving force of the spring 22 and quickly impacts from the energy storage position to the release position to complete the impact simulation. When the far end of the main rod 1 is abutted against the surface of the body sheet metal, the impact head of the impact member 21 impacts the surface of the body sheet metal, thereby simulating impact damage. The impact force corresponds to the compression force of the spring 22. Therefore, by quantitatively compressing the spring 22, the impact force can be precisely guaranteed to be the same for each impact, which makes it easier to create simulated damage with consistent damage area and damage degree.

[0036] Example 2

[0037] like Figure 1 As shown, the present invention provides a body panel damage simulator, comprising a main rod 1, an impact simulation mechanism 2, and a scratch simulation mechanism 3. Specifically, the main rod 1 has a proximal end and a distal end, the impact simulation mechanism 2 is fitted at the distal end of the main rod 1, and the scratch simulation mechanism 3 is fitted at the proximal end of the main rod 1. The impact simulation mechanism 2 and the scratch simulation mechanism 3 perform impact simulation and scratch simulation using the same operation as in Embodiment 1 described above.

[0038] The improvement of this embodiment is as follows:

[0039] Firstly, the scratch simulation mechanism 3 and the main rod 1 are detachably connected, facilitating disassembly and replacement of the scratch simulation mechanism 3. Specifically, the scratch simulation mechanism 3 includes the guide 31 and the scratching component 32 disclosed in Embodiment 1 above. The scratching component 32 includes a mounting base 321 and a scratching blade 322 rotatably mounted on the mounting base 321; wherein, the mounting base 321 is provided with... Figure 4 The connecting screw 323 shown has an axial connecting screw hole at the near end of the main rod 1 that mates with the connecting screw 323. Based on this, the sliding part 32 and the main rod 1 can be quickly assembled and disassembled by threading the connecting screw 323 into the axial connecting screw hole.

[0040] Secondly, the impact simulation mechanism 2 includes an impact member 21, a spring 22, and an adjusting member 23 assembled within the hollow 11. The spring 22 applies an elastic driving force to the impact member 21 along a predetermined impact direction, causing the impact member 21 to generate an impact simulation motion stroke along the impact direction. This impact simulation motion stroke includes an energy storage position where the impact member 21 is fully accommodated within the hollow 11, compressing the spring 22 to store energy, and a release position where the impact member 21 at least partially protrudes from the opening 12 to simulate an impact. The adjusting member 23 has an adjusting motion stroke that applies an overcoming force to the spring 22 to increase its compression. Specifically, the impact member 21 is... Figure 2 The sliding assembly shown is the impact rod inside the hollow 11 of the main rod body 1, and the adjusting member 23 is... Figure 2 The sliding assembly shown is a limiting rod inside the hollow 11 of the main rod body 1.

[0041] Optionally, the adjusting member 23 is connected to the impact member 21 so that the spring 22 is fitted between the adjusting member 23 and the proximal end of the main rod 1 (not shown in the figure). Specifically, when the adjusting member 23 moves away from the impact member 21, the distance between the adjusting member 23 and the proximal end of the main rod 1 shortens, thereby compressing the spring 22 to increase the elastic driving force exerted by the spring 22 on the impact member 21.

[0042] Alternatively, the adjusting member 23 is connected to the proximal end of the main rod 1, so that the spring 22... Figure 2 The assembly shown is between the adjusting member 23 and the impact member 21. Specifically, when the adjusting member 23 moves closer to the impact member 21, the distance between the adjusting member 23 and the impact member 21 shortens, thereby compressing the spring 22 to increase the elastic driving force exerted by the spring 22 on the impact member 21.

[0043] Regarding the movement drive of the adjusting member 23, the impact member 21 or the main rod 1 is provided with an axial adjustment screw hole at its near end. The adjusting member 23 is connected to an adjusting screw 231 that cooperates with the axial adjustment screw hole. A locking nut 232 for pressing against the impact member 21 or the short rod 120 is sleeved on the adjusting screw 231. Thus, the adjusting member 23 is driven to move based on the helical cooperation between the adjusting screw 231 and the axial adjustment screw hole. The locking nut 232 ensures the stability of the positioning of the adjusting member 23 after movement, avoiding the positional displacement of the adjusting member 23 due to the vibration generated during the impact, thereby ensuring the accuracy of the impact force and the simulated impact damage degree.

[0044] In addition, it should be noted that both ends of the spring 22 are equipped with protrusions 25 to prevent the spring 22 from sliding radially within the hollow 11. One end of the protrusion 25 is fixed to the adjusting member 23, and the other end of the protrusion 25 is fixed to the impact member 21 or the short rod 120. The protrusion 25 extends into the spring 22 or has a cavity on the protrusion 25 to accommodate the end of the spring 22.

[0045] Thirdly, the main rod 1 is designed as a detachable assembly structure to facilitate the operation and adjustment of the positioning position of the adjusting member 23. Specifically, the main rod 1 includes a long rod 110 and a short rod 120. The hollow part 11 is located in the long rod 110, and the proximal end of the hollow part 11 is a threaded part that connects to the short rod 120, so that the short rod 120 closes the proximal end of the hollow part 11. In this embodiment, the guide 31 is connected to the middle of the short rod 120, the sliding part 32 is connected to the proximal end of the short rod 120, and the adjusting member 23 is connected to the short rod 120; that is, the radial hole 121 is located in the middle of the short rod 120, the axial connecting screw hole is located in the proximal end of the short rod 120, and the axial adjusting screw hole is located in the distal end of the short rod 120. Based on this, the adjusting member 23 can be removed by unscrewing the short rod 120, thus making the movement and adjustment operation of the adjusting member 23 more convenient.

[0046] In summary, this invention provides a vehicle body sheet metal damage simulator that integrates the impact simulation mechanism 2 and the scratch simulation mechanism 3 into one unit. It features a simple structure, convenient operation, and is suitable for standardized simulation of various common vehicle body sheet metal damages, effectively meeting the application needs of teaching, training, or competitions. Furthermore, its impact simulation mechanism 2 can flexibly adjust the elastic driving force applied by the spring 22 to the impact component 21 through the movement of the adjusting component 23, facilitating the simulation of impact damage under different application forces according to different training needs, thereby improving training effectiveness.
