Description

Technical Field

[0001] This utility model relates to the field of protective device technology, and more specifically, to a car chassis protective device. Background Technology

[0002] In the existing technology, existing chassis protection devices generally have the problem of inconvenience in operation during installation and use. Since most traditional protection devices are connected to the car chassis by bolts, clips or welding, although these connection methods are strong, their installation or disassembly usually requires the use of special tools, and the operation steps are cumbersome and time-consuming.

[0003] Furthermore, the existing device lacks a convenient and efficient fixing mechanism, making it impossible to quickly connect and disconnect the protective device from the chassis. Especially during vehicle maintenance, inspection, or chassis cleaning, the protective device needs to be temporarily removed, and the existing structure does not provide an efficient way to handle this, resulting in low efficiency during use and hindering routine maintenance and repair work.

[0004] More importantly, current chassis protection devices lack flexibility in structural design. Once installed, they are difficult to adjust according to specific working conditions or user needs. The protection device and chassis are usually connected in a fixed manner, which makes it impossible to achieve quick and controllable assembly and disassembly operations. This not only affects the vehicle maintenance efficiency, but also limits the universality and widespread application of the protection device to a certain extent. Utility Model Content

[0031] Please see Figures 1-5 A vehicle chassis protection device includes a chassis 1, on which a drive assembly is provided. The drive assembly includes a transmission assembly 2, a drive shaft 3, a hinge shaft 4, a drive assembly 5, and a wheel 6. The transmission assembly 2 is located on the chassis 1, the drive shaft 3 is located at one end of the transmission assembly 2, the hinge shaft 4 is located at the output end of the transmission assembly 2, the drive assembly 5 is located at both ends of the chassis 1, and the wheel 6 is located at the output end of the drive assembly 5. A protection assembly is provided on the chassis 1, which includes a protective shell 7, an abutment rod 8, and an abutment plate 9. The protective shell 7 is detachably installed at the bottom of the chassis 1, the abutment rod 8 is slidably connected to the protective shell 7 and the chassis 1, and the abutment plate 9 is connected to one end of the chassis rod and abuts against one end of the protective shell 7.

[0032] A first spring 10 is installed at the connection between one end of the wheel 6 and the disc 1.

[0033] The end of the abutment rod 8 that passes through the disc body 1 is detachably fitted with an installation sleeve 11, and a rotating ring 12 is rotatably connected to the installation sleeve 11.

[0034] Rotating rods 13 are evenly installed on the rotating ring 12, and a movable ring 14 is slidably connected to the mounting sleeve 11.

[0035] A second spring 15 is evenly connected between the moving ring 14 and the mounting sleeve 11. A through groove 16 is evenly opened on the moving ring 14, and the through groove 16 is adapted to the rotating rod 13.

[0036] In this embodiment, during use, the disc body 1 is placed at the bottom of the vehicle body, and the drive shaft 3 on the disc body 1 is connected to the drive end on the vehicle body. During use, the drive shaft 3 drives the transmission assembly 2, and as the transmission continues, the hinge shaft 4 connected to the transmission assembly 2 is activated, thereby activating the drive assemblies 5 at both ends of the disc body 1, causing the wheels 6 on them to rotate, thus completing the driving process of the disc body 1. Furthermore, during use, the first spring 10 buffers the impacts that occur during use. When the protective shell 7 needs to be quickly removed from the bottom of the disc 1, the rotating ring 12 rotates along the mounting sleeve 11, causing the rotating rod 13 on it to rotate. When the rotating rod 13 is rotated to be aligned with the through groove 16 on the moving ring 14, the restriction on the rotating rod 13 is released, allowing the moving ring 14 to slide along the mounting sleeve 11 under the elastic potential energy of the second spring 15.

[0037] Please see Figure 4 As an embodiment of a car chassis protection device for locking components: a locking component is provided on the mounting sleeve 11. The locking component includes an internal gear 17, an insertion rod 18, and a tension spring 19. The internal gear 17 is rotatably connected to the mounting sleeve 11. The insertion rod 18 is slidably connected to the internal gear 17. The tension spring 19 is provided at one end of the insertion rod 18. The tension spring 19 is connected to the insertion rod 18 and the internal gear 17. The insertion rod 18 passes through the internal gear 17 and is inserted into the mounting sleeve 11.

[0038] The mounting sleeve 11 has an insertion slot 20 that is adapted to the insertion rod 18. The mounting sleeve 11 is rotatably connected to a second threaded rod 21. One end of the second threaded rod 21 is connected to a first gear 22, which meshes with an internal gear 17. A moving block 23 is threadedly connected to the second threaded rod 21. An adjusting ring 24 is installed on the moving block 23. A rack 25 is evenly installed on the adjusting ring 24.

[0039] The mounting sleeve 11 is rotatably connected to a second gear 26. The inner side of the second gear 26 is threadedly connected to a first threaded rod 27. One end of the first threaded rod 27 is connected to a threaded block 28. The abutment rod 8 is evenly provided with abutment grooves 29, which are adapted to the threaded block 28. The inner side of the mounting sleeve 11 is provided with a storage groove 30, which is adapted to the threaded block 28. The transmission shaft 3 is equipped with a transmission gear 31, which is responsible for driving the transmission assembly 2.

[0040] More specifically, during the continuous sliding movement of the moving ring 14, it releases its contact with the outer side of the insertion rod 18. After releasing the contact, under the elastic potential energy of the tension spring 19, it drives one end of the insertion rod 18 to move out of the insertion groove 20 of the mounting sleeve 11, thereby releasing the fixing process of the internal gear 17. At this time, the internal gear 17 rotates along the mounting sleeve 11. As it rotates, it causes the first gear 22, which is meshed with its inner side, to rotate. As it rotates, it causes the second threaded rod 21 on the first gear 22 to rotate, causing the moving block 23 on it to move. As it moves, the adjusting ring 24 on it moves along the mounting sleeve 11. 1. The sliding movement process is carried out, which moves the rack 25 on it. As the rack 25 moves, the second gear 26 that meshes with it rotates along the outside of the mounting sleeve 11. During the continuous rotation, the first threaded rod 27 that is threaded to its inner side moves continuously. During the movement, the threaded block 28 at one end of the first threaded rod 27 moves from the abutment groove 29 of the abutment rod 8 to the receiving groove 30 of the mounting sleeve 11, thereby releasing the fixing process of the abutment rod 8. Then, the abutment rod 8 is removed from the mounting sleeve 11, the protective shell 7 and the disc 1. Then, the mounting sleeve 11 is removed, thereby releasing the fixing process of the protective shell 7 and the disc 1, so that the protective shell 7 can be removed for replacement or repair.

[0041] In summary, during use or operation of the overall equipment: During use, the disc 1 is positioned at the bottom of the vehicle body, and the drive shaft 3 on the disc 1 is connected to the drive end on the vehicle body. This drives the drive shaft 3, which in turn drives the transmission assembly 2. As the transmission continues, the hinge shaft 4 connected to the transmission assembly 2 is activated, thereby driving the drive assemblies 5 at both ends of the disc 1. This causes the wheels 6 on these assemblies to rotate, thus completing the driving of the disc 1. During the operation, the first spring 10 cushions the impacts that occur during use. When the protective shell 7 needs to be quickly removed from the bottom of the disc 1, the rotating ring 12 rotates along the mounting sleeve 11, causing the rotating rod 13 on it to rotate. When the rotating rod 13 is rotated to be aligned with the through groove 16 on the moving ring 14, the restriction on the rotating rod 13 is released, allowing the moving ring 14 to slide along the mounting sleeve 11 under the elastic potential energy of the second spring 15.

[0042] During the continuous sliding movement of the moving ring 14, it releases its contact with the outer side of the insertion rod 18. After releasing the contact, under the action of the elastic potential energy of the tension spring 19, it drives one end of the insertion rod 18 to move out of the insertion groove 20 of the mounting sleeve 11, thereby releasing the fixing process of the internal gear 17. At this time, the internal gear 17 rotates along the mounting sleeve 11. As it rotates, it causes the first gear 22, which is meshed with its inner side, to rotate. As it rotates, it causes the second threaded rod 21 on the first gear 22 to rotate. During this rotation, it drives the moving block 23 on it to move. As it moves, it causes the adjusting ring 24 on it to move along the mounting sleeve 11. During the sliding movement process, the rack 25 on it is moved. As the rack 25 moves, the second gear 26 meshing with it rotates along the outer side of the mounting sleeve 11. During the continuous rotation, the first threaded rod 27, which is threaded to its inner side, moves continuously. During this movement, the threaded block 28 at one end of the first threaded rod 27 moves from the abutment groove 29 of the abutment rod 8 to the receiving groove 30 of the mounting sleeve 11, thereby releasing the fixing process of the abutment rod 8. Then, the abutment rod 8 is removed from the mounting sleeve 11, the protective shell 7, and the disc 1. Then, the mounting sleeve 11 is removed, thereby releasing the fixing process of the protective shell 7 and the disc 1, so that the protective shell 7 can be removed for replacement or repair.

For all the fixed connections mentioned above, welding is preferred.
