Description

Technical Field

[0001] This utility model belongs to the field of wheel limiting technology for automobile repair, and in particular relates to a wheel limiting device for automobile repair. Background Technology

[0002] In the maintenance of new energy vehicles, wheel limiters are core equipment for ensuring maintenance safety. Because new energy vehicles generally use electric drive systems, maintenance often involves frequent chassis inspections and battery pack removal. If a wheel rolls, it can easily cause vehicle displacement, leading to safety accidents such as tool crushing or high-voltage electrical contact. In traditional maintenance scenarios, mechanical wheel limiters, with their single-slot design, cannot accommodate the diverse wheel hub structures and wheel diameters of new energy vehicles, resulting in insecure installation and the potential for wheel displacement.

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0013] Example This embodiment describes a wheel limiting device for automobile repair, such as... Figures 1 to 4 As shown, it includes a horizontally arranged base plate 1, on which a limiting groove is provided to restrict the movement of the wheel. The limiting groove is connected to the rear side wall of the base plate 1. In use, the base plate 1 is inserted from one side of the car wheel so that the wheel is located in the limiting groove.

[0014] On the left and right sides of the corresponding limiting groove, a limiting arm 2 that can swing left and right is hinged to the base plate 1. The base plate 1 has a hinge groove, and the hinged end of the limiting arm 2 is hinged to the hinge groove via a hinge post. A fixing sleeve 7 is independently fitted onto the hinge post, with one end of the fixing sleeve 7 fixed to the hinged end of the limiting arm 2. The fixing sleeve 7 is independently fitted onto the hinge post and fixed to the limiting arm 2, used to constrain the back-and-forth movement of the limiting arm 2 within the hinge groove. Fixing holes are provided at both ends of the hinge post within the hinge groove, and both ends of the hinge post are inserted into the fixing holes. A hinge hole is provided at the hinged end of the limiting arm 2, communicating with the interior of the fixing sleeve 7. The hinge hole is independently fitted onto the hinge post, allowing the limiting arm 2 to swing left and right.

[0015] The swing end of the limiting arm 2 is fixed with a fixing rod that restricts the movement of the wheel. After the limiting arm 2 is fixed, the fixing rods on both sides fit against the outer surface of the wheel to restrict the wheel's movement and limit its left and right rolling. A freely rotatable clamping plate 4 is provided on the fixing rod, and the clamping surface of the clamping plate 4 is an arc surface that fits against the wheel. The clamping plate 4 has a front and rear through mounting hole, and the fixing rod is independently installed in the mounting hole. One end of the fixing rod passes through the mounting hole and is fixed with a second limiting ring to prevent the clamping plate 4 from falling off. The clamping plate 4 can rotate freely around the center line of the fixing rod, so that the clamping plate 4 can fit against the wheel surface at any angle when the limiting arm 2 swings, thus providing better stability and restriction for the car wheel.

[0016] Both limiting arms 2 are hinged with connecting rods 3. The limiting arms 2 have connecting holes that are open from front to back. The hinged end of the connecting rod 3 is fixed with a pivot. The pivot is independently installed in the connecting hole and can rotate freely, so that the connecting rod 3 can swing. At the same time, the other end of the pivot is independently connected to a first limiting ring 8 through the connecting hole. The first limiting ring 8 is fitted on the pivot and restricts the pivot from detaching from the connecting hole.

[0017] One connecting rod 3 has a swing end connected to a freely rotatable adjusting sleeve 6, and the other connecting rod 3 has an external thread at its swing end, while the adjusting sleeve 6 has an internal thread that engages with it. This section together constitutes an adjusting assembly that connects the swing ends of the two connecting rods 3 and adjusts their overall length.

[0018] A limiting ring is fixed inside the adjusting sleeve 6. A limiting groove is provided at the swing end of a connecting rod 3 to prevent the limiting ring from detaching. The limiting ring, when fitted into the limiting groove, can move left and right and rotate freely. The limiting groove restricts the limiting ring from detaching, thus constraining the adjusting sleeve 6 from the connecting rod 3. Through the cooperation between the limiting ring and the limiting groove, the adjusting sleeve 6 can move left and right to a certain extent while also rotating freely. During production, to ensure the adjusting sleeve 6 can independently rotate within the limiting groove, the adjusting sleeve 6 and the limiting ring are divided into two equal parts, front and back. These two parts can be connected by screws. During installation, the two parts are fitted together from front to back onto the swing end of the connecting rod 3, so that the limiting ring is located within the limiting groove.

[0019] In use, after swinging the connecting rod 3, the center lines of the two connecting rods 3 are aligned. Then, the sliding adjusting sleeve 6 is connected to the other connecting rod 3, and then rotated to connect the two connecting rods 3 together. As the adjusting sleeve 6 rotates, under the action of the internal and external threads, the two connecting rods 3 shorten to a certain extent after being connected by the adjusting sleeve 6, while the limiting arms 2 on both sides swing, fixing the wheel through the clamping plate 4. The shorter the overall length of the two connecting rods 3, the tighter the clamping of the wheel. At the same time, the shorter the overall length of the two connecting rods 3, the smaller the wheel that can be fixed.

[0020] A nut 5 is fitted onto the adjusting sleeve 6. The nut 5 makes it easier for the operator to rotate the adjusting sleeve 6. By using a wrench and the nut 5 to rotate the adjusting sleeve 6, the clamping plate 4 can be made to grip the wheel more securely. A silicone pad can also be placed on the clamping surface of the clamping plate 4 to increase the friction between it and the wheel.

[0021] In practical use, the base plate 1 is placed under the wheel, positioning it within the limiting groove. Then, the two limiting arms 2 are moved to allow the clamping plate 4 to adhere to the wheel. Next, the two connecting rods 3 are swung together, and the adjusting sleeve 6 is rotated to shorten the overall length of the connecting rods 3. This allows the swing ends of the limiting arms 2 to move, using the clamping plate 4 to hold the wheel securely, thus fixing wheels of different diameters within a certain range. Furthermore, this product does not require locking the wheel using the wheel hub's clearance, therefore it has no requirements regarding the wheel hub's structure, making its application range wider.
