Description

Technical Field

[0001] This utility model relates to the field of scooter accessories technology, specifically to an optimized connection structure between the scooter connecting arm and the frame. Background Technology

[0002] Scooters, as a convenient and flexible means of transportation, play an important role in daily life and short-distance travel. Scooters have a large number of parts, among which the frame is the main supporting component of the vehicle, and its structural stability affects the overall driving safety of the vehicle. The frame is also generally equipped with connecting arms, which have different uses depending on their location. The connecting arm installed at the front of the vehicle mainly serves the purpose of steering.

[0003] However, most scooter connecting arms use a bearing connection structure to ensure smoother rotation. However, the bearings in this type of connection are essentially exposed, which, while reducing friction, makes them susceptible to rust from rain and other sources, thus failing to provide adequate waterproofing. Therefore, we propose an optimized connection structure for the scooter connecting arm and frame. Utility Model Content

[0004] The purpose of this invention is to provide an optimized connection structure between the scooter connecting arm and the frame, so as to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An optimized connection structure for a scooter's connecting arm and frame includes a frame and a connecting arm mounted on the frame. A support arm is fixedly mounted on the frame, and a support cylinder is fixedly mounted on the support arm. Two symmetrical bearings are fixedly mounted on the inner wall of the support cylinder. The connecting arm passes through the two bearings and is fixedly mounted on the inner ring of the bearings. A vertically positioned water-retaining cylinder is fixedly mounted at the top of the support cylinder. A fixing sleeve is fixedly mounted on the connecting arm. The fixing sleeve has a covering groove whose bottom communicates with the outside. The fixing sleeve is fitted onto the water-retaining cylinder and is rotatably connected to the water-retaining cylinder.

[0007] Preferably, the height of the water-blocking cylinder is between 1.5cm and 3cm, and more than half of the cylinder body of the fixing sleeve is fitted onto the water-blocking cylinder.

[0008] Preferably, the top surface of the support cylinder is provided with an inclined surface, which is inclined downward at 45° to 60°.

[0009] Preferably, a plurality of heat-conducting plates are fixedly installed on the annular side of the support cylinder, and the heat-conducting plates are arranged along the height direction of the support cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting a fixed sleeve to fit over the water-blocking cylinder, can provide rain protection from the top, making it difficult for rainwater to enter the internal bearing parts and cause the bearing to rust. In addition, the fixed sleeve and the water-blocking cylinder are rotatably connected, so as not to affect the normal rotation of the connecting arm, thus achieving the effect of waterproof protection.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figures 1-5 This utility model provides a technical solution: an optimized connection structure between a scooter connecting arm and a frame, including a frame 1 and a connecting arm 3 mounted on the frame 1. A support arm 10 is fixedly mounted on the frame 1, and a support cylinder 11 is fixedly mounted on the support arm 10. Two symmetrical bearings 2 are fixedly mounted on the inner wall of the support cylinder 11. The connecting arm 3 passes through the two bearings 2 and is fixedly mounted on the inner ring of the bearings 2. A vertically arranged water-blocking cylinder 13 is fixedly mounted at the top of the support cylinder 11. A fixing sleeve 31 is fixedly mounted on the connecting arm 3. The fixing sleeve 31 has a covering groove 311 with its bottom communicating with the outside. The fixing sleeve 31 is fitted onto the water-blocking cylinder 13 and is rotatably connected to the water-blocking cylinder 13. The height of the water-blocking cylinder 13 is between 1.5cm and 3cm. More than half of the cylinder of the fixing sleeve 31 is fitted onto the water-blocking cylinder 13, realizing the water-blocking protection operation by using the fixing sleeve 31 fitted onto the water-blocking cylinder 13.

[0028] In this embodiment, an inclined surface 12 is provided on the top surface of the support cylinder 11. The inclined surface 12 is inclined downward at 45° to 60° so that rainwater dripping on the inclined surface 12 can slide down the inclined surface 12 more effectively.

[0029] Specifically, multiple heat-conducting plates 14 are fixedly installed on the annular side of the support cylinder 11. The heat-conducting plates 14 are arranged along the height direction of the support cylinder 11 so that the heat-conducting plates 14 can conduct heat to the support cylinder 11 due to friction.

[0030] Furthermore, the top cylinder of the support cylinder 11 is provided with a lubricating oil injection hole 15 that communicates with the inside of the support cylinder 11, so as to facilitate the injection of lubricating oil into the support cylinder 11 through the lubricating oil injection hole 15. The lubricating oil injection hole 15 is set at an upward tilt of 45°, so that rainwater is less likely to enter through the lubricating oil injection hole 15.

[0031] In addition, an annular groove 17 is provided on the inner wall of the support cylinder 11, and a limiting plate 30 is fixedly installed on the connecting arm 3. The limiting plate 30 is located in the annular groove 17 and is rotatably connected to the annular groove 17, which serves to limit and support the connecting arm 3.

[0032] It is worth noting that two symmetrical support rings 16 are fixedly installed on the inner wall of the support cylinder 11. The outer ring of the bearing 2 abuts against the upper surface of the support rings 16, which provides stable support for the bearing 2.

[0033] It is worth noting that a bottom collar 18 is fixedly installed on the inner wall of the bottom cylinder of the support cylinder 11. The bottom collar 18 is provided with multiple drainage holes 181, so that even if rainwater enters the support cylinder 11, it can be discharged outward through the drainage holes 181.

[0034] In use, the optimized connection structure of the scooter connecting arm and frame of this utility model involves placing the bearing 2 against the support protrusion 16, passing the connecting arm 3 through the bearing 2, fixing the connecting arm 3 on the inner ring of the bearing 2, fixing the outer ring of the bearing 2 on the inner wall of the support cylinder 11, ensuring that the limiting plate 30 is in the annular groove 17, and ensuring that the fixing sleeve 31 is fitted on the water baffle 13, thus completing the assembly operation.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
