[0002] A vehicle support is a device used to support and secure a vehicle or vehicle components. Especially during vehicle repair, a vehicle support is needed to lift and support the vehicle so that repair personnel can have a clearer view of the underside of the vehicle.

[0003] There are two common types of vehicle bracket structures: one is as follows Figure 1 The standard bracket shown requires manually pulling up the rack during lifting. Once the rack is raised to the working height, the latch can be engaged before use. This method necessitates manual adjustment of the rack, making it laborious and cumbersome. Another type... Figure 2 The pneumatic spring bracket shown requires lifting the latch when the rack is in a low position, and the rack is lifted by the force of the gas spring. However, when lowering, the rack needs to be manually pressed down to the low position. This bracket requires overcoming the elastic force of the gas spring during use, and still has the problems of being laborious to operate and inconvenient to use.

[0004] In view of the above-mentioned existing technology, it is necessary to improve the structure of the existing vehicle bracket. To this end, the applicant has made a useful design, and the technical solution to be introduced below is produced in this context. Utility Model Content

[0006] The purpose of this utility model is achieved as follows: a vehicle bracket includes a bracket body, a rack that moves vertically within the bracket body, and a latch that engages with the tooth groove of the rack after movement. The rack has multiple stops at certain intervals on its side. A dial with a certain number of wings is provided on the outer side of the rack. The dial is fixed to the bracket body and driven by a power source. When the dial rotates, each wing contacts the stop in sequence, causing the rack to rise. The latch automatically fits into the next tooth groove of the rack under the action of gravity, thus fixing the rack.

[0007] In a specific embodiment of this utility model, a handle for controlling the action of the latch is also included. The bracket body has a collar formed at the top. The latch is linked to one end of the handle. This end of the handle is hinged to the collar and the latch is accommodated inside the collar. When the handle is lifted, the latch disengages from the rack. The wing can rotate in the opposite direction when the power source is not started, so that the rack descends without obstruction.

[0008] In another specific embodiment of this utility model, the power source is equipped with a power source fixing plate, the dial is equipped with a dial fixing plate, the power source fixing plate and the dial fixing plate are fixed to the collar on one side of the collar in parallel with each other, the collar is provided with an wing clearance hole corresponding to the dial, and the wing passes through the wing clearance hole to cooperate with the stop block.

[0009] In another specific embodiment of this utility model, the dial has a central shaft, the two ends of which are supported by a pair of bushings. The pair of bushings are respectively disposed face-to-face on the dial fixing plate and the power source fixing plate. The power source is a micro motor. The motor shaft of the micro motor passes through the power source fixing plate and is then inserted into the central shaft of the dial for transmission connection. When the micro motor rotates, the rack is lifted by the dial. When the micro motor is not working, the latch is fully engaged with the tooth groove under the action of gravity.

[0010] In another specific embodiment of this utility model, a sheet metal cover is also included, which is disposed over the dial and power source and is assembled with the collar.

[0011] Due to the adoption of the above-mentioned structure, this utility model has the following advantages compared with the prior art: the rack can be raised by rotating the dial, making operation effortless and easy; the rack can be quickly lowered by lifting the handle, ensuring the operability and stability of the product.

[0019] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of this utility model should be considered within the protection scope of this utility model.

[0020] In the following description, all directional (or orientational) concepts involving up, down, left, right, front, and back refer to the position of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be construed as a special limitation on the technical solution provided by this utility model.

[0021] See Figure 3 and Figure 6 This utility model relates to a vehicle support, comprising a support body 1, a rack 2 disposed within the support body 1 for vertical movement, a latch 3 that engages with the tooth grooves 21 of the rack 2 after movement, a handle 4 for controlling the movement of the latch 3, and a bracket 8 fixed to the top of the rack 2 for supporting a load. The rack 2 is a unidirectional rack with multiple stops 22 formed at equal intervals on its side. A dial 5 with a certain number of wings 51 is fitted on the outer side of the rack 2. The wings 51 engage with the stops 22; when the dial 5 rotates, each wing 51 contacts the stop 22 in sequence, causing the rack 2 to rise. The spacing of the stops 22 depends on the tooth pitch of the rack 2 and the size of the latch 3. The length and number of wings 51 depend on the distance between the dial 5 and the rack 2, and the distance between adjacent stops 22 and between the stops 22 and the inner arm of the rack 2.

[0022] See Figure 5 and combined Figure 3 The dial 5 is fixed to the support body 1 and driven by the power source 6. The support body 1 has a collar 11 at the top. The power source 6 is equipped with a power source fixing plate 61, and the dial 5 is equipped with a dial fixing plate 54. The power source fixing plate 61 and the dial fixing plate 54 are fixed to the collar 11 on one side of the collar 11, which is parallel to each other. The collar 11 has a wing clearance hole 111 corresponding to the dial 5. The wing 51 passes through the wing clearance hole 111 and cooperates with the stop block 22.

[0023] Specifically, the dial 5 has a central shaft 52, the two ends of which are supported by a pair of bushings 53. The pair of bushings 53 are respectively disposed face-to-face on the dial fixing plate 54 and the power source fixing plate 61. In this embodiment, the power source 6 is preferably a micro motor. The motor shaft of the micro motor passes through the power source fixing plate 61 and is connected to the central shaft 52 of the dial 5. When the micro motor rotates, one wing 51 of the dial 5 contacts the stop block 22 and drives the stop block 22 to rise by rotating the dial 5, which in turn drives the rack 2 to rise. At this time, there is no need to operate the handle 4. When one wing 51 is about to leave the stop block 22, the latch 3 will automatically fit into the next tooth groove 21 of the rack 2 under the action of gravity to fix the rack 2. At this time, there needs to be a certain distance between the next wing 51 and the next stop block 22 so that the latch 3 and the tooth groove 21 on the rack 2 can be fully engaged, thereby ensuring the safety and stability of the bracket during use.

[0024] The latch 3 is linked to one end of the handle 4, which is hinged to the collar 11, allowing the latch 3 to be accommodated inside the collar 11. When the handle 4 is lifted, the latch 3 disengages from the rack 2, unlocking the latch 2. In this embodiment, the wing 51 can rotate in the opposite direction when the power source 6 is not activated. Therefore, when the latch 2 descends due to the lack of engagement of the latch 3, the rack 2 can descend normally and quickly without obstruction, ensuring the operability of the product.

[0025] Further details can be found here. Figure 4 The present invention also includes a sheet metal cover 7, which is installed over the dial 5 and the power source 6 and is assembled with the collar 11 to protect the moving parts and reduce the operational risks to the operators.

[0026] When the present invention needs to be lifted, simply rotate the dial 5; when the rack 2 needs to be lowered and reset, simply pull the handle 4. The operation is labor-saving and simple, and has a good safety factor, thus achieving the purpose of the invention.
