Description

Technical Field

[0001] This application relates to the field of bicycle accessory technology, and in particular to a high-strength bicycle kickstand. Background Technology

[0002] Bicycle kickstands can be divided into single-sided kickstands and double-sided kickstands. The support of a single-sided kickstand is significantly less than that of a double-sided kickstand. Most existing double-sided kickstands are made of a single bent metal rod. Although they can play a good stabilizing role, when they are in place, the rear wheel of the bicycle is not under load. The kickstand bears all the pressure above it. Since the load-bearing capacity of the kickstand is limited by the structural strength of the metal rod, when a heavy object is placed on the bicycle, the kickstand may deform and come into contact with the wheel, thus losing its supporting function. Utility Model Content

[0003] The purpose of this application is to provide a high-strength bicycle kickstand that can increase the load-bearing capacity of a bicycle.

[0004] To achieve the above objectives, this application provides a high-strength bicycle kickstand: it includes a support frame, a pair of side legs fixedly connected to the support frame, a support frame fixedly connected between the two side legs and the support frame, a pressure plate fixedly connected between the bottom of the support frame and the inner wall of the support frame, and a rear leg fixedly connected between the side of the support frame and the upper surface of the support frame. The rear leg moves further away from the support frame as it goes down, forming a positive cone shape, which provides better placement stability.

[0005] As a preferred embodiment, the support frame is open on one side between the side legs, and the support frame includes a bridging strip, the two ends of which are fixedly connected to the two ends of the open side of the support frame to maintain a stable distance between the two ends of the open side of the support frame.

[0006] As a preferred embodiment, the pressure plate has two front ends and two rear ends. The two front ends are fixedly connected to the side of the bridging strip and are respectively close to both ends of the bridging strip. The two rear ends are fixedly connected to the inner side of the support frame away from the bridging strip, thereby increasing the contact area with the ground when the foot support is raised and improving the structural strength of the support frame.

[0007] As a preferred embodiment, the upper surface of the bridging strip also has a pair of inner pillars, the upper ends of which are fixedly connected to the sides of the two side legs respectively, thereby improving the deformation resistance of the inclined side legs.

[0008] As a preferred embodiment, the upper ends of the two rear support legs are fixedly connected to the sides of the two inner support columns, and the lower ends of the two rear support legs are fixedly connected to the upper surface of the support frame away from the bridging strip, thereby improving the deformation resistance of the inner support columns.

[0009] As a preferred embodiment, the side legs are positioned closer together towards the top, with the upper ends of the two side legs being parallel to each other and having coaxial shaft holes for engaging with the limiting shaft on the frame to form a rotating pair.

[0010] As a preferred embodiment, the two side legs have spring-loaded retaining posts on opposite sides of their upper ends, and the ends of the spring-loaded retaining posts have retaining rings to prevent the hooks or loops at the ends of the reset springs from slipping off the ends of the spring-loaded retaining posts.

[0011] As a preferred embodiment, the lower surfaces of the support frame and the bridging strip are fixedly connected to an elastic pad, and the lower surface of the elastic pad is provided with a friction groove to further increase the contact friction between the elastic pad and the ground.

[0012] Compared with the prior art, the beneficial effects of this application are as follows: (1) By setting a support frame structure on the inside of the side leg and setting a rear leg structure between the support frame and the support frame, the side leg has a higher resistance to deformation, and the entire bicycle kickstand can bear a greater weight when it is up. (2) By designing a pressure plate, the contact area between the bicycle kickstand and the ground is increased when the kickstand is raised, and the contact pressure is reduced. Even on unstable ground, when the bicycle is carrying heavy loads, the kickstand will not sink too deep, and the bicycle kickstand will be easier to lift and return to its original position.

[0020] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0022] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0023] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0024] like Figure 1-6 The high-strength bicycle kickstand shown includes a support frame 1, which is roughly C-shaped. A pair of side legs 3 are fixedly connected to the support frame 1. The side legs 3 are located at the ends of the C-shape. A support frame 4 is fixedly connected between the two side legs 3 and the support frame 1. Since the support frame 1 is open on one side between the side legs 3, the specific structure of the support frame 4 includes a bridging strip 401. The two ends of the bridging strip 401 are fixedly connected to the two ends of the open side of the support frame 1, respectively.

[0025] The side support legs 3 move closer together towards the top, so the main body of each side support leg 3 is inclined. The upper ends of the two side support legs 3 are parallel to each other and have coaxial shaft holes 302 for the limit shaft on the frame to pass through and form a rotating pair with the entire bicycle kickstand. The opposite sides of the upper ends of the two side support legs 3 have spring limit posts 301, which can be caught by hooks or rings at the ends of the springs, thereby limiting the position of one end of the spring on the outside of the kickstand. The ends of the spring limit posts 301 have retaining rings 6 to prevent the hooks or rings at the ends of the springs from detaching from the ends of the spring limit posts 301. The upper surface of the bridging bar 401 also has a pair of inner support pillars 402. The upper ends of the two inner support pillars 402 are fixedly connected to the opposite inner sides of the two side support legs 3, respectively, to provide stable support for the side support legs 3.

[0026] A pressure plate 2 is fixedly connected between the bottom of the support frame 4 and the inner wall of the support frame 1. The pressure plate 2 is X-shaped and has two front ends and two rear ends. The two front ends are fixedly connected to the sides of the bridging strip 401 and are close to both ends of the bridging strip 401, respectively. The two rear ends are fixedly connected to the inner side of the support frame 1 away from the bridging strip 401 and are also close to both ends of the support frame 1 away from the bridging strip 401, respectively.

[0027] The side of the support frame 4 is fixedly connected to the upper surface of the support frame 1 with a rear support leg 5. The rear support leg 5 moves further away from the support frame 4 as it goes down, so the rear support leg 5 is also tilted. The upper ends of the two rear support legs 5 are fixedly connected to the upper part of the side of the two inner pillars 402 respectively. The lower ends of the two rear support legs 5 are fixedly connected to the upper surface of the support frame 1 away from the bridging strip 401. The two rear support legs 5 are arranged symmetrically.

[0028] The lower surfaces of the support frame 1 and the bridging strip 401 are fixedly connected to a rubber elastic pad 7 to prevent the alloy bicycle kickstand from making direct hard contact with the ground. The lower surface of the elastic pad 7 is provided with a friction groove 701 to further enhance the contact friction between the elastic pad 7 and the ground.

[0029] Working principle: When the bicycle kickstand is not in use, the side support leg 3 is roughly horizontal and the support frame 1 is roughly vertical, maintained by a spring connected to the frame. When the bicycle needs to be parked, an upward force is applied to the rear of the bicycle, causing it to lift slightly. At the same time, downward pressure is applied to the side support leg 3, causing it to swing downward. The side support leg 3 is roughly vertical and the support frame 1 is roughly horizontal. The rear of the bicycle is lowered, allowing the elastic pad 7 to directly contact the ground. The two side support legs 3 provide support for the bicycle frame. Since the kickstand is shaped like a cone with a larger lower end and a smaller upper end, it can maintain stability well. On the other hand, the rear support leg 5 provides inclined support to the two inner support columns 402, improving the deformation resistance of the inner support columns 402. The two inner support columns 402, in turn, provide support to the two side support legs 3 respectively, allowing the inclined side support legs 3 to withstand higher loads, thus giving the entire bicycle kickstand higher structural strength.

[0030] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
