Description

Technical Field

[0001] This utility model relates to the field of electric locomotive technology, and in particular to a retractable booster roller bracket for electric locomotives. Background Technology

[0002] Electric vehicles are lightweight and fast, making them particularly suitable for short-distance travel, commuting, and shopping. Therefore, their use is becoming increasingly widespread. However, when an electric vehicle experiences a tire blowout, it cannot move normally, and the rider must manually tow it to a repair shop. This is extremely physically demanding, and the towing process can easily cause further damage to the tire and rim, severely affecting the normal use of the electric vehicle. Chinese utility model patent, authorized publication number "CN220009718U", discloses a booster roller bracket for electric motorcycles, including a support frame; two support frames are provided, arranged in a parallel configuration; each support frame has a scissor-type telescopic rod; several rotating rods are rotatably mounted on the scissor-type telescopic rod; a fixing component is provided on the support frame; the fixing component is used to fix the position of the electric motorcycle tire; and rollers are rotatably mounted on the bottom of the support frame.

[0003] The above technical solution adjusts the direction by rotating the first and second fixed rods on the ring. After adjustment, it is then connected to the corresponding threaded hole by a long bolt to fix the position of the tire. A baffle can also be used to help fix the position of the tire, making it less likely to slip. However, the above technical solution still has certain defects. Since the roller of the device is directly fixed to the movable plate, when the electric motorcycle tire is placed on the roller bracket, the roller bracket is prone to move under the action of the roller, making it inconvenient to place the electric motorcycle on the roller bracket. This makes it difficult to accurately place the motorcycle tire in the predetermined position, which may require repeated adjustments, wasting time and effort. Therefore, this utility model proposes a new solution. Utility Model Content

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequential relationship of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Please see Figure 1-7 This utility model provides a technical solution: a telescopic booster roller bracket for an electric motor vehicle, including a first roller bracket 1, which is U-shaped, and a roller bracket limiting assembly disposed on the first roller bracket 1. The roller bracket limiting assembly includes a fixed bracket 8, which is fixedly connected to the inner side of the first roller bracket 1. A threaded rod 9 is rotatably connected inside the first roller bracket 1. Two fixed rods 10 are fixedly connected to the opposite surfaces of the first roller bracket 1 and the fixed bracket 8. A handwheel 18 is fixedly connected to the front end of the threaded rod 9. A movable plate 11 is threadedly sleeved on the surface of the threaded rod 9. The movable plate 11 is connected to two... A fixed rod 10 is slidably connected, and a locking block 14 is fixedly connected to both the left and right sides of the movable plate 11. A second sliding groove 12 is opened on the inner wall of the first roller bracket 1, and a third sliding groove 13 is opened at the bottom of the first roller bracket 1. The second sliding groove 12 and the third sliding groove 13 are interconnected. A second roller bracket 15 is slidably connected inside the third sliding groove 13. The second roller bracket 15 extends into the interior of the second sliding groove 12 and is slidably connected to the second sliding groove 12. A limit block 16 is fixedly connected to the surface of the second roller bracket 15. The opposing surfaces of the locking block 14 and the second roller bracket 15 are both inclined. A roller 17 is installed inside the second roller bracket 15.

[0033] The number of movable plates 11 and locking blocks 14 are two sets, arranged in a linear array on the front and rear sides of the threaded rod 9. The number of second slide grooves 12, third slide grooves 13, second roller brackets 15, limiting blocks 16 and rollers 17 are four, respectively symmetrically arranged on the left and right sides of the first roller bracket 1.

[0034] The inner wall of the first roller bracket 1 is fixedly connected to a tire support frame 2. The tire support frame 2 is "S" shaped and concave in the middle. The side of the tire support frame 2 closest to the handwheel 18 is raised upwards, and the side of the tire support frame 2 away from the handwheel 18 is tilted downwards. Multiple through grooves are opened on the surface of the tire support frame 2, and multiple reinforcing ribs are fixedly connected to the lower surface of the tire support frame 2.

[0035] The first roller bracket 1 has inclined first grooves 4 on both the left and right sides. The first grooves 4 are "L" shaped. An inclined fixing plate 3 is fixedly connected to the inner side of the first roller bracket 1. A guide plate 5 is slidably connected to the upper end of the fixing plate 3. A connecting shaft 6 is fixedly connected inside the guide plate 5. The connecting shaft 6 is slidably connected to the two first grooves 4.

[0036] Multiple anti-slip pads 7 are fixedly connected to the lower end of the first roller bracket 1.

[0037] When using the device, push it to the side of the electric vehicle with a flat tire. The anti-slip pad 7 at the lower end of the first roller bracket 1 will be in close contact with the ground to increase friction and prevent the device from sliding randomly during operation, providing stable support for subsequent operations. At the same time, observe the tire position and adjust the guide plate 5. Since the first roller bracket 1 has an "L"-shaped and inclined first slide groove 4 on both sides, the upper end of the inner fixing plate 3 is slidably connected to the guide plate 5. The connecting shaft 6 inside the guide plate 5 slides with the first slide groove 4. The guide plate 5 can be slid along the slide groove according to the actual situation, and the connecting shaft 6 is locked in the vertical groove of the first slide groove 4, so that the free end of the guide plate 5 is in contact with the ground and the tire is accurately placed on the tire support frame 2.

[0038] Align the side of the electric vehicle with the side of the flat tire with the tire support frame 2; the tire support frame 2 is "S" shaped with a concave center, with the side closer to the handwheel 18 tilting upwards and the side further away from the handwheel 18 tilting downwards. This special shape facilitates tire placement; during tire placement, the tilted end can guide the tire to initial positioning, the concave part can better hold the tire in place, and the multiple through grooves on the surface reduce the overall weight without affecting the support strength, while the reinforcing ribs at the lower end further enhance the load-bearing capacity of the support frame.

[0039] Turning the handwheel 18 causes the threaded rod 9 to rotate. Since the movable plate 11 is threaded onto the threaded rod 9 and is slidably connected to the fixed rod 10 fixed on the opposite side of the first roller bracket 1 and the fixed bracket 8, the movable plate 11 will move along the direction of the fixed rod 10 when the threaded rod 9 rotates. There are two sets of locking blocks 14 on each side of the movable plate 11. As the movable plate 11 moves, the locking blocks 14 also move synchronously.

[0040] The opposing surfaces of the locking block 14 and the second roller bracket 15 are inclined. When the locking block 14 moves, its inclined surface pushes the second roller bracket 15. The second roller bracket 15 slides in the third sliding groove 13 at the bottom of the first roller bracket 1 and the second sliding groove 12 on the inner wall (the second sliding groove 12 and the third sliding groove 13 are interconnected). There are four of each of the second roller bracket 15, the limiting block 16 and the roller 17, which are symmetrically distributed on the left and right sides of the first roller bracket 1. Under the push of the locking block 14, the second roller bracket 15 gradually extends, driving the roller 17 to descend until the roller 17 contacts the ground and lifts the electric vehicle tire to a certain height, so that the electric vehicle can move by relying on the roller 17.

[0041] The use of the limiting block 16 can limit the second roller bracket 15 when it slides inside the second slide groove 12 and the third slide groove 13, prevent the second roller bracket 15 from disengaging from the second slide groove 12 and the third slide groove 13, and improve the stability of the second roller bracket 15.

[0042] After the roller 17 contacts the ground, it pushes the electric vehicle. The roller 17 rolls on the ground, driving the electric vehicle to move. The limit block 16 is fixed to the surface of the second roller bracket 15, which can prevent the second roller bracket 15 from falling out of the slide groove during the sliding process and ensure the stable operation of the device.

[0043] Furthermore, the movement of the second roller bracket 15 and the locking block 14 facilitates the adjustment of the position of the roller 17, making it easier to maintain stability during use. At the same time, it provides a stable support structure for the descent of the roller 17 and the lifting of the electric vehicle, preventing the roller bracket from shifting during use and improving the stability and safety of the roller bracket.

[0044] The use of guide plate 5 facilitates the guidance of electric vehicles and provides auxiliary support for them. At the same time, guide plate 5 can be retracted into the first roller bracket 1, which facilitates the extension and retraction of the guide plate and improves the practicality and convenience of the roller bracket.

[0045] The anti-slip pad 7 is designed to increase the friction between the first roller bracket 1 and the ground during the support of the electric vehicle, thereby improving the stability of the first roller bracket 1 and enhancing the safety of the roller bracket during use.

[0049] Threaded rod 9: Rotatably connected inside the first roller bracket 1, driven to rotate by handwheel 18, and using threaded transmission to move the movable plate 11 along the direction of fixed rod 10, providing a power source for the movement of the locking block 14;

[0050] Fixed rod 10: Fixed to the opposite side of the first roller bracket 1 and the fixed bracket 8. The movable plate 11 is slidably connected to the two fixed rods 10, which plays a guiding role and ensures that the movable plate 11 can only move along the direction of the fixed rod 10, thereby ensuring the accuracy of the movement direction of the locking block 14.

[0051] Handwheel 18: Fixed to the front end of threaded rod 9, allowing operators to manually rotate threaded rod 9 to provide power input to the entire transmission system;

[0052] Movable plate 11: It is threaded onto the threaded rod 9 and slidably connected to the fixed rod 10. When the threaded rod 9 rotates, it moves along the direction of the fixed rod 10, thereby driving the locking block 14 fixedly connected to it to move.

[0053] Block 14: Fixed on the left and right sides of the movable plate 11, it pushes the second roller bracket 15 to slide in the groove through its own inclined surface, so as to realize the extension and retraction of the second roller bracket 15, thereby controlling the lifting and lowering of the roller 17.

[0054] The second slide rail 12 is formed on the inner wall of the first roller bracket 1 and is connected to the third slide rail 13. It provides a sliding track for the second roller bracket 15, restricts its movement direction, and ensures the stability and accuracy of the movement of the second roller bracket 15.

[0055] The third slide 13 is formed at the bottom of the first roller bracket 1 and communicates with the second slide 12. The second roller bracket 15 slides in it and works in cooperation with the second slide 12 to provide space and guidance for the movement of the second roller bracket 15.

[0056] The second roller bracket 15 slides within the third slide groove 13 and the second slide groove 12. A roller 17 is installed inside the bracket.

[0059] Tire support bracket 2: It is "S" shaped and concave in the middle. The side closer to the handwheel 18 is raised upward and the side away from the handwheel 18 is tilted downward. The raised end guides the initial positioning of the tire, the concave part better holds the tire, and the multiple through grooves on the surface reduce the overall weight without affecting the support strength. The reinforcing rib at the lower end further enhances the load-bearing capacity of the support bracket. It is used to place and support the tire on the side of the electric vehicle that has blown out.

[0060] First groove 4: It is formed on the left and right sides of the first roller bracket 1, in the shape of "L" and inclined, and is slidably connected to the connecting shaft 6 inside the guide plate 5. The position of the guide plate 5 can be adjusted according to the actual situation to guide the tire to be accurately placed on the tire support frame 2.

[0061] Fixed plate 3: Fixed to the inner side of the first roller bracket 1, in an inclined shape, its upper end provides sliding support for the guide plate 5, and cooperates with the first slide groove 4 to realize the adjustment of the position of the guide plate 5;

[0062] Guide plate 5: It has a connecting shaft 6 fixedly connected inside, which is slidably connected to the first slide groove 4. Its free end can be in contact with the ground to guide the tire to be accurately placed on the tire support frame 2.

[0063] Connecting shaft 6: Fixed inside the guide plate 5, and slidably connected to the first slide groove 4, so that the guide plate 5 can move within the first slide groove 4, thereby adjusting the position of the guide plate 5;

[0064] Anti-slip pad 7: Fixed to the lower end of the first roller bracket 1, it is in close contact with the ground, increases friction, prevents the device from sliding randomly during operation, and provides stable support for subsequent operations.
