Description

Technical Field

[0001] This utility model relates to the field of balance assistance technology for motorcycles and electric vehicles, and in particular to a motorcycle balance landing gear. Background Technology

[0002] Motorcycle landing gear, as a riding balance aid, is widely used in scenarios such as novice driving training, heavy-duty transportation, or driving on complex road conditions. Its core function is to improve the stability of the motorcycle and avoid the risk of tipping over.

[0003] However, traditional balance landing gears mostly use rigid connection structures and lack effective buffer components. During riding, the impact force generated by road bumps is directly transmitted to the motorcycle frame and training wheels themselves, which not only affects riding comfort, but also easily leads to loosening of the wheel frame connection (especially for frames with multiple crank extensions, such as the patent with authorization announcement number CN114728678B - a motorcycle landing device with vertically arranged training wheels), fatigue damage of parts, and reduced service life of training wheels.

[0004] Therefore, we propose a motorcycle balance landing gear. Utility Model Content

[0005] In view of this, the present invention provides a motorcycle balance landing gear to solve the problem of the lack of effective cushioning in existing motorcycle balance landing gears.

[0006] A motorcycle balance landing gear includes a wheel frame body and a buffer seat. A round rod is fixedly connected to one side of the connecting seat of the wheel frame body, a round block is fixedly connected to one end of the round rod, and a plate is fixedly connected to the bottom of the round block. A polyurethane rubber block is fitted on the round block and the plate, and the polyurethane rubber block is fixedly installed inside the buffer seat.

[0007] Preferably, the polyurethane rubber block is provided with a through-hole, the through-hole matching the shape of the round block and the plate, and the round block and the through-hole are interference fit.

[0008] Preferably, the buffer seat described above includes a housing and a cover plate, the cover plate being fixedly installed on the top of the housing by bolts; a rectangular mounting opening is provided inside the housing, the polyurethane rubber block is inserted into the mounting opening, and a vertical strip-shaped notch is provided on one side of the housing, the width of the strip-shaped notch being greater than the diameter of the round rod and smaller than the diameter of the round block; the round rod passes through the strip-shaped notch.

[0009] Preferably, the thickness of the aforementioned circular block is 0.05-0.2 mm less than the width of the mounting opening.

[0010] Preferably, the cover plate is provided with a through hole, the top of the housing is provided with a first threaded hole, and the lower end of the bolt passes through the through hole from top to bottom and is threaded into the first threaded hole.

[0011] Preferably, the back of the aforementioned housing is provided with a second threaded hole, through which the housing can be fixed to the motorcycle frame by means of the second threaded hole and screws.

[0012] Preferably, the polyurethane rubber block described above is made of medium-soft polyurethane rubber with a Shore A hardness of 40-80.

[0013] Preferably, the polyurethane rubber block described above is made of medium-hard polyurethane rubber with a Shore hardness of D40-60.

[0014] Implementing the embodiments of this utility model will have the following beneficial effects: After adopting the aforementioned motorcycle balance landing gear, Using polyurethane rubber blocks as the core buffer element, it has both a certain degree of rigidity and good elasticity and damping characteristics. It can efficiently absorb the impact energy generated by road bumps, effectively reduce the transmission of impact force to the motorcycle frame, protect the wheel frame body, extend its service life, and improve comfort to a certain extent. Through the design of the round rod, round block and the shell of the buffer seat and the strip notch, the round rod can swing up and down and deflect to a certain extent with the bumps, which meets the buffer stroke requirements. It has a better buffering effect on complex road surfaces (such as roads with shallow steps, shallow potholes or stones), and can prevent the wheel frame body from shaking significantly, thus ensuring the structural stability during driving.

[0015] The buffer seat adopts a split design of shell and cover plate, with fewer parts and simple assembly process. It is fixed by bolts, and the cover plate can be opened by simply removing the bolts, so as to realize the quick disassembly and replacement of polyurethane rubber block and low maintenance cost.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Example 1

[0022] Please see Figure 1-4 A motorcycle balance landing gear includes a wheel frame body 100 and a buffer seat 200. A round rod 301 is fixedly connected to one side of the connecting seat 300 of the wheel frame body 100. A round block 302 is fixedly connected to one end of the round rod 301. A plate 303 is fixedly connected to the bottom of the round block 302. A polyurethane rubber block 500 is fitted on the round block 302 and the plate 303. The polyurethane rubber block 500 is fixedly installed inside the buffer seat 200.

[0023] The wheel frame body 100 is existing technology, such as the wheel frame structure disclosed in the patent with authorization announcement number CN114728678B - Motorcycle landing device with vertically arranged auxiliary wheels. The polyurethane rubber block 500 is made of medium-soft polyurethane rubber with a Shore hardness of A40-80 (usually A60-70 is selected).

[0024] In specific implementation, such as Figure 4 As shown, a through-hole 501 is provided on the polyurethane rubber block 500. The shape of the through-hole 501 matches that of the round block 302 and the plate 303, and the round block 302 and the through-hole 501 are interference fit.

[0025] Among them, such as Figure 3 and Figure 4 As shown, the buffer seat 200 includes a housing 201 and a cover plate 203. The cover plate 203 is fixedly installed on the top of the housing 201 by bolts 400. A rectangular mounting opening 205 is provided inside the housing 201. A polyurethane rubber block 500 is inserted into the mounting opening 205. A vertical strip-shaped notch 206 is opened on one side of the housing 201. The width of the strip-shaped notch 206 is greater than the diameter of the round rod 301 and smaller than the diameter of the round block 302. The round rod 301 passes through the strip-shaped notch 206.

[0026] Specifically, the thickness of the circular block 302 is 0.05-0.2mm less than the width of the mounting opening 205. This design is mainly to limit the forward and backward movement of the circular block 302.

[0027] During implementation, a through hole 204 is provided on the cover plate 203, and a first threaded hole 207 is provided on the top of the housing 201. The lower end of the bolt 400 passes straight down through the through hole 204 and is threaded into the first threaded hole 207.

[0028] Additionally, a second threaded hole 202 is provided on the back of the housing 201, through which the housing 201 can be fixed to the motorcycle frame using the second threaded hole 202 and screws. Example 2

[0029] Unlike Example 1, the polyurethane rubber block 500 in this example is made of medium-hard polyurethane rubber with a Shore hardness of D40-60 (usually D40-50 is selected).

[0030] The polyurethane rubber block 500 (Shore hardness A40-80) in Example 1 is biased towards shock absorption and cushioning, but its support is relatively weak. It is suitable for children's motorcycles, light motorcycles, women's motorcycles, etc.

[0031] The polyurethane rubber block 500 in this embodiment is more geared towards enhancing support, but its cushioning effect is relatively low, making it suitable for adult motorcycles and men's motorcycles. During implementation, it should be designed appropriately according to needs and style.

[0032] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this application's specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the scope of patent protection of this application.
