Description
Technical Field
[0001] This utility model relates to the field of automobile model technology, specifically to an automobile model tire tilt angle adjustment device. Background Technology
[0002] Car models are scale models made strictly according to the shape, structure, color, and even interior parts of real cars. These models not only have aesthetic value, but are also regarded as works of art due to their exquisite craftsmanship and detailed depiction. When using car models, the camber angle of their tires often needs to be adjusted.
[0003] Existing patent CN222347138U discloses a car model tire tilt angle adjustment device, relating to the field of car model technology. This device includes a connecting rod, one end of which is welded to a connecting shell. Inside the connecting shell is a wheel axle base rotatably connected to its front and rear inner walls. The front and rear inner walls of the wheel axle base both have storage grooves. This new car model tire tilt angle adjustment device uses a small-diameter toothed roller to drive a large-diameter gear. When the indicator disc rotates a large range (e.g., 1 degree), the wheel axle base only swings 0.2 degrees, effectively improving the accuracy of the car model tire tilt angle adjustment. Adjustment is convenient. Simultaneously, the slide and the limiting strip directly bear the pressure, while the first and second bolts assist in bearing the pressure. The first and second bolts do not bend or deform, ensuring the stability of the car model tire after tilt angle adjustment.
[0004] Based on the search of the aforementioned patents and in conjunction with the adjustment devices in the prior art, it was found that although the aforementioned adjustment devices can adjust the tire camber angle during use, they are fixed with bolts during adjustment. The bolts need to be loosened and tightened repeatedly before and after adjustment, which reduces the adjustment efficiency and thus reduces the practicality. Utility Model Content
[0005] The purpose of this utility model is to provide a tire camber adjustment device for automobile models, in order to solve the problem mentioned in the background art that, although the existing adjustment devices can adjust the tire camber, they are fixed with bolts during adjustment, and the bolts need to be loosened and tightened repeatedly before and after adjustment, which reduces the adjustment efficiency and thus reduces the practicality.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a car model tire tilt angle adjustment device, including a connecting shell, a connecting rod provided inside the connecting shell, a wheel axle base fixedly connected to one end of the connecting rod, and an adjustment component provided on the connecting shell;

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By setting up a connecting shell, connecting rod, wheel and axle base and adjusting components, the rotation of the worm gear can drive the rotation of the worm wheel, which in turn drives the rotation of the pinion gear, which in turn drives the rotation of the large gear, thereby driving the wheel and axle base to adjust the tilt angle.

[0022] 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.
[0023] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: a car model tire camber adjustment device, including a connecting shell 1, a connecting rod 11 inside the connecting shell 1, a wheel axle base 12 fixedly connected to one end of the connecting rod 11, and an adjustment component on the connecting shell 1. The adjustment component includes a first rotating shaft 21 fixedly connected to the connecting rod 11, a large gear 22 fixedly connected to the outside of the first rotating shaft 21, a small gear 23 connected to one side of the large gear 22, a second rotating shaft 24 fixedly connected to the small gear 23, an indicator disk 25 fixedly connected to the outside of the second rotating shaft 24, a worm gear 26 fixedly connected to the outside of the second rotating shaft 24, a worm 27 connected to the worm gear 26, and a locking component for further improving the fixing effect of the connecting rod 11. The worm gear 26 meshes with the worm 27. Both the first rotating shaft 21 and the second rotating shaft 24 are rotatably connected to the connecting shell 1. The large gear 22... The worm gear 27 meshes with the pinion 23, and the rotation of the worm gear 27 drives the worm wheel 26 to rotate. The rotation of the worm wheel 26 drives the second shaft 24 to rotate, which in turn drives the pinion 23 to rotate. The pinion 23 drives the large gear 22 to rotate, which in turn drives the first shaft 21 and the connecting rod 11 to rotate. This allows for adjustment of the tilt angle of the axle base 12. At the same time, the self-locking characteristics of the worm gear 27 and worm wheel 26 prevent the axle base 12 from rotating arbitrarily, thus locking it in place. The connecting shell 1 has a connecting plate 51 inside, which is fixedly connected to the inner wall of the connecting shell 1. The second shaft 24 is rotatably connected to the connecting plate 51. The connecting plate 51 supports the rotation of the second shaft 24, improving the rotational stability of the second shaft 24 and preventing it from swinging during rotation, thereby improving the stability of the tilt angle adjustment.
[0024] Please see Figure 1 , Figure 2 , Figure 4 as well as Figure 5The locking components include a support plate 31 connected to both sides of the worm gear 27, a rotating plate 32 fixedly connected to the top of the worm gear 27, an extension plate 33 fixedly connected to the front of the rotating plate 32, a sliding opening 34 opened at the top of the extension plate 33, a sliding groove 35 opened on the inner wall of the sliding opening 34, a locking rod 36 provided in the sliding opening 34, a sliding plate 37 fixedly connected to the outside of the locking rod 36, a first spring 38 fixedly connected to the top of the sliding plate 37, and a plurality of locking holes 39 arranged circumferentially on the support plate 31. The locking rod 36 is slidably connected to the sliding opening 34, the sliding plate 37 is slidably connected to the sliding groove 35, and the locking rod 36 is slidably connected to the sliding opening 34. 6 is inserted into the locking hole 39. Vertical movement of the vertical rod allows the sliding plate 37 to move, simultaneously disengaging it from the current locking hole 39. The movement of the sliding plate 37 compresses the first spring 38, causing it to deform. At this point, the worm gear 27 is released and can rotate to adjust the tire tilt angle. The reset of the first spring 38 causes the locking rod 36 to reset, allowing it to insert into the locking hole 39 and lock the worm gear 27. This further improves the stability of the wheel axle base 12, preventing it from rotating and resetting. A first pull plate 361 is fixedly connected to the top of the locking rod 36. A first pull ring 362 facilitates the movement of the first pull plate 361, which in turn facilitates the vertical movement of the locking rod 36. A vertical plate 41 is fixedly connected to the top of the rotating plate 32. A locking rod 42 is provided on one side of the vertical plate 41, and multiple evenly arranged slots 43 are provided on one side of the locking rod 36. A moving ring 44 is fixedly connected to the outside of the locking rod 42. A second spring 45 is fixedly connected between the moving ring 44 and the vertical plate 41. The locking rod 42 is inserted into the slots 43, passes through the vertical plate 41, and is slidably connected to the vertical plate 41. Pulling the locking rod 42 moves the moving ring 44. When the locking lever 42 disengages from the slot 43, it can simultaneously compress the second spring 45, causing it to deform and releasing the locking lever 36, facilitating its vertical movement. The reset of the second spring 45 allows the locking lever 42 to engage with the slot 43, thus securing the locking lever 36. This prevents the locking lever 36 from moving vertically and allows for easy adjustment of the tire tilt angle by a single person. One end of the locking lever 42 is fixedly connected to a second pull plate 421, and a second pull ring 422 is fixedly connected to one side of the second pull plate 421. The second pull ring 422 can drive the second pull plate 421 to move, thereby facilitating the movement of the locking lever 42.
[0025] Working principle: During operation, when the tilt angle needs to be adjusted, the second pull ring 422 can be pulled to move the locking rod 42. The movement of the locking rod 42 can drive the moving ring 44 to move, which can compress the second spring 45 and deform it. At the same time, the locking rod 42 moves out of the current slot 43, and the locking rod 36 is released. The first pull ring 362 can then be pulled to move the locking rod 36 vertically, disengaging it from the current lock hole 39. Simultaneously, the sliding plate 37 can be moved, which can compress the first spring 38 and deform it. At this time, the worm gear 27 is released. The second pull ring 422 is then released, and the second spring 45 returns to its original position, pushing the locking rod 42 into the slot 43, thus locking the locking rod 36. Then, rotating the rotating plate 32 can drive the rotating plate 32 to rotate, which in turn drives the worm gear 27 to rotate. The rotation of the worm gear 27 causes the worm wheel 26 to rotate, which in turn ... The second rotating shaft 24 and the small gear 23 rotate, which drives the large gear 22 to rotate. The large gear 22 drives the first rotating shaft 21 and the wheel axle base 12 to rotate, thereby adjusting their tilt angle. Utilizing the self-locking characteristics of the worm gear 27 and worm wheel 26, the wheel axle base 12 can be prevented from rotating arbitrarily, thus locking it. Then, the second pull ring 422 can be pulled again. At this time, the locking rod 42 disengages from the slot 43, and the first spring 38 resets, pushing the locking rod 36 to reset and engage in the locking hole 39, thus locking the worm gear 27. Then, the second pull ring 422 is released, and the second spring 45 resets, driving the locking rod 42 to engage in the slot 43, thus locking the worm gear 27 a second time, further preventing the worm gear 27 from rotating and preventing the wheel axle base 12 from rotating and resetting. The above is the working process of the entire device, and all contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
