Description

Technical Field

[0001] This utility model relates to the field of automotive repair equipment technology, and in particular to a mobile bracket for body panel repair. Background Technology

[0002] In the automotive repair industry, body panel repair is a common and important task. When repairing, painting, or shaping body panels such as doors, hoods, or trunk lids, it is usually necessary to use a special mobile support to support and fix these parts so that repair personnel can operate at the appropriate height and angle. Traditional supports usually use a pin-type or simple telescopic tube structure to adjust the height. This method often requires repair personnel to hold the heavy body panel with one hand and operate the pin or tighten the screw with the other hand. This is not only laborious, but also makes it difficult to achieve millimeter-level fine adjustments, resulting in poor adjustment accuracy. At the same time, since the adjustment mechanism is usually located at the bottom of the support, repair personnel need to frequently bend over or squat down to operate, increasing the labor intensity.

[0003] Existing brackets mostly have rigid structures at the points of contact with the vehicle body, lacking effective cushioning and protection designs. If the operating speed is not properly controlled, a hard collision can easily occur when the support bracket lifts and contacts the door or sheet metal parts, resulting in scratches or bumps to the delicate paint surface and causing secondary damage. Furthermore, the rigid contact surface lacks elastic feedback during operation, making it difficult to effectively clamp irregularly shaped sheet metal parts, leading to workpiece instability and affecting repair quality.

[0004] Therefore, this utility model proposes a movable bracket for body panel repair to overcome the shortcomings of the prior art. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 6 This utility model provides a mobile support for body panel repair, including a vertical plate 1 as the overall support base and a fixed cover 3 fixedly connected to the top of the vertical plate 1. The vertical plate 1 is placed vertically, and the fixed cover 3 is horizontally set on the top of the vertical plate 1. The inner wall of the vertical plate 1 has a through guide groove 15 in the vertical direction. The guide groove 15 serves as a lifting component. A slider 16 is slidably connected to the inner wall of the guide groove 15. The shape of the slider 16 is adapted to the cross-sectional shape of the guide groove 15, so that the slider 16 can move smoothly up and down in a straight line within the guide groove 15. A support frame 17 is fixedly connected to the left side of the slider 16. The support frame 17 rises and falls synchronously with the slider 16. The support frame 17 is connected to the vertical plate 1 at an adjustable height through the slider 16, thereby realizing the flexible change of the overall working height of the support.

[0031] Please refer to Figure 1 and Figure 5To achieve drive control of the slider 16 and support frame 17, the movable bracket also includes a drive mechanism installed between the upright plate 1 and the slider 16. The drive mechanism includes a crank handle 6, a rotating shaft 7, a spur gear 12, a spur gear 13, a rotating shaft 14, and a rope 5. The crank handle 6 serves as the power input end, and a handle 11 is fixedly connected to its right end. The outer surface of the handle 11 is provided with anti-slip texture to increase friction when the operator holds the handle 11 and rotates the crank handle 6, preventing the hand from slipping. A rotating shaft 7 is fixedly connected to the center of the inner wall of the crank handle 6. The rotating shaft 7 is horizontally inserted and rotatably supported on the relevant mounting structure. The rotation of the crank handle 6 directly drives the rotating shaft 7 to rotate around its axis. By manually cranking, the rotational torque is transmitted to the subsequent transmission, which is then converted into the vertical lifting and lowering motion of the slider 16.

[0032] Please refer to Figure 1 and Figure 4 Spur gear 12 is fixedly installed on one side of the outer wall of shaft 7. The teeth of spur gear 12 are meshed with the teeth of spur gear 13. The rotational torque input by shaft 7 is transmitted to spur gear 13 through gear meshing. Shaft 14 is fixedly connected to the center hole of the inner wall of spur gear 13, so that shaft 14 can rotate synchronously with spur gear 13. Rope 5 serves as a flexible traction medium connecting the drive end and the execution end. One end of rope 5 is fixedly wrapped around the outer wall of shaft 14, and the other end of rope 5 extends downward and is fixedly connected to the top end face of slider 16. When shaft 14 is rotated under force, rope 5 is wound or released on shaft 14, thereby traction slider 16 to produce vertical displacement in guide groove 15.

[0033] Please refer to Figure 1 , Figure 4 and Figure 5 To ensure the stability of the rope 5's trajectory and prevent deviation during transmission, an arc-shaped groove 4 is provided on the front outer wall of the fixed cover 3. The middle part of the rope 5 is embedded and slidably connected in the inner wall of the arc-shaped groove 4. The arc-shaped groove 4 serves as a limiting guide for the rope 5, ensuring that the direction of the tension is always parallel to the guide groove 15. To achieve self-locking and suspension of the crank handle 6 at any adjustment position, a concave plate 9 is rotatably sleeved on the outer wall of the middle part of the rotating shaft 7, and a nut 8 is threaded on the outer wall of the rotating shaft 7. The nut 8 is fitted against one side of the concave plate 9. By turning the nut 8, the clamping force on the side wall of the concave plate 9 is adjusted, thereby changing the frictional resistance when the rotating shaft 7 rotates, so that the crank handle 6 can rotate smoothly and stop at any time against gravity. A protective shell 10 is also fixedly connected to the inner wall of the concave plate 9. The protective shell 10 covers the external space of the spur gear 13 and the rotating shaft 14, serving as a dustproof and safety protection function.

[0034] Please refer to Figure 1 , Figure 4 and Figure 6 The support frame 17 is provided with an anti-collision buffer mechanism 2. The anti-collision buffer mechanism 2 includes a fixedly installed support arm 201 and a support plate 203 that can move relative to each other. The support plate 203 is slidably connected in the internal space of the support arm 201. A vertically downward connecting column 204 is fixedly connected at the bottom center of the support plate 203. A movable plate 205 is fixedly connected at the bottom end of the connecting column 204. The movable plate 205 serves as an intermediate transmission component. A fixed column 1 206 is fixedly connected to the inner wall of the movable plate 205. A rotating plate 207 is rotatably connected to the outer circumferential wall of the fixed column 1 206. The rotating plate 207 serves as a linkage mechanism. A fixed column 208 is rotatably connected to the inner wall of the other end of the rotating plate 207. Through the above connection structure, the vertical pressure on the support plate 203 is converted into the motion transmission of the linkage system.

[0035] In order to accurately guide and limit the moving parts inside the buffer mechanism, a square groove 202 is provided on the inner wall of the support arm 201. A fixing plate 210 is fixedly connected to the inner wall of the square groove 202. A sliding groove 211 is provided on the inner wall of the fixing plate 210 in the horizontal direction. The outer wall of the second fixing column 208 slides in the inner wall of the sliding groove 211, so that when the second fixing column 208 is driven by the rotating plate 207, it can only move horizontally and reciprocally along the length of the sliding groove 211, thereby converting the vertical displacement into the horizontal displacement.

[0036] Please refer to Figure 1 , Figure 3 and Figure 5 The inner space of the slide groove 211 is provided with a spring column 209. One end of the spring column 209 is fixedly connected to the right side of the outer wall of the second fixed column 208, and the other end of the spring column 209 is fixedly connected to the inner wall of the slide groove 211. When the second fixed column 208 slides horizontally in the slide groove 211, it will exert a squeezing effect on the spring column 209. The elastic deformation force of the spring column 209 itself is used to resist and buffer the external impact, which not only avoids the damage caused by rigid contact, but also assists in clamping the door through elastic feedback.

[0037] Working principle: Since the fixed cover 3 is fixed to the top of the upright plate 1, the upright plate 1 provides support for the fixed cover 3. Since the guide groove 15 is opened on the inner wall of the upright plate 1, the slider 16 is slidably connected to the inner wall of the guide groove 15, so the slider 16 can slide in the guide groove 15. Since the support frame 17 is fixedly connected to the left side of the slider 16, the slider 16 can drive the support frame 17 to move together. Since the handle 11 is fixedly connected to the right side of the crank handle 6, and the rotating shaft 7 is fixedly connected to the inner wall of the crank handle 6, rotating the handle 11 can drive the crank handle 6 to rotate, and the crank handle 6 drives the rotating shaft 7 to rotate. Since the nut 8 is threadedly connected to the outer wall of the rotating shaft 7, and the concave plate 9 is rotatably connected to the middle of the outer wall of the rotating shaft 7, rotating the nut 8 increases the friction between the crank handle 6 and the outer wall of the concave plate 9, allowing the crank handle 6 to rotate and stop at any time. Since the spur gear 12 is fixedly connected to one side of the outer wall of the rotating shaft 7, and the spur gear 13 meshes with the spur gear 12, the rotation... Shaft 7 can drive spur gear 12 to rotate, and spur gear 12 drives spur gear 23 to rotate. Since shaft 2 14 is fixedly connected to the inner wall of spur gear 2 13, spur gear 2 13 drives shaft 2 14 to rotate. Since the protective shell 10 is fixedly connected to the inner wall of the concave plate 9, the protective shell 10 protects shaft 2 14. Since the arc groove 4 is opened on the front side of the outer wall of the fixed cover 3, and the middle part of the rope 5 is slidably connected to the inner wall of the arc groove 4, the arc groove 4 guides the rope 5 and prevents it from deviating. Since one end of the rope 5 is fixed to the outer wall of shaft 2 14 and the other end is fixed to the top of the slider 16, the shaft 2 14 rotates to retract or lower the rope 5, thereby driving the slider 16 to move up or down along the guide groove 15, realizing the position adjustment of the support frame 17. The gear meshing makes the operation more labor-saving, the lifting accuracy higher, and there is no need to bend over and squat below. The structural layout is more flexible, the lifting stroke is longer, and the adaptability is stronger.

[0038] When the support frame 17 rises and presses against the car door, the car door first contacts the support plate 203 in the anti-collision buffer mechanism 2. Since the support plate 203 is fixedly connected to the top of the connecting column 204, the support plate 203 drives the connecting column 204 to move downward. Since the moving plate 205 is fixedly connected to the bottom of the connecting column 204, and the first fixed column 206 is fixedly connected to the inner wall of the moving plate 205, the connecting column 204 drives the moving plate 205 to move downward. The moving plate 205 drives the first fixed column 206 to move downward. Since the rotating plate 207 is rotatably connected to the outer wall of the first fixed column 206, and the second fixed column 208 is rotatably connected to the inner wall of the rotating plate 207, the first fixed column 206 drives the rotating plate 207 to rotate. At the same time, the rotating plate 207 rotates and drives the second fixed column 208 to move. Since the second fixed column 208 slides... The movable connection is to the inner wall of the slide groove 211, so the second fixed post 208 moves horizontally under the restriction of the slide groove 211. Since the slide groove 211 is opened on the inner wall of the fixed plate 210, the fixed plate 210 is fixedly connected to the inner wall of the square groove 202, and the square groove 202 is opened on the inner wall of the support arm 201, the support arm 201 provides a fixed position for the fixed plate 210. Since one end of the spring post 209 is fixedly connected to the right side of the outer wall of the second fixed post 208, and the other end is fixedly connected to the inner wall of the slide groove 211, the second fixed post 208 squeezes the spring post 209 when it moves. Due to the action of the spring post 209 itself, it resists this force, thereby playing a buffering role. This not only avoids hard collisions that scratch the paint, but also helps to clamp the door with elastic force, improving the operational error tolerance and protecting the bracket itself.
