Description

Technical Field

[0001] This application relates to the field of four-wheeled vehicle technology, and in particular to a standing four-wheeled vehicle. Background Technology

[0002] Existing recreational four-wheeled vehicles are typically seated. To accommodate these vehicles and allow them to move beyond the seated configuration, a type of vehicle that allows users to stand on the footrest has emerged, such as the convertible recreational seated-to-standing vehicle proposed in publication CN116829445A, which allows for flexible switching between seated and standing modes. However, the standing mode of this vehicle is only designed to accommodate the user's body shape and cannot effectively utilize the advantages of a standing vehicle. When a person stands up, the seat only rests on the area below the buttocks, lacking lumbar support. On challenging terrain, more effort is required to control the body. Therefore, the purpose of this application is to solve the above problems.

[0003] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0004] Based on this, this application provides a standing four-wheeled vehicle to solve one of the aforementioned technical problems.

[0005] The technical solution adopted by this application to solve its technical problem is a standing four-wheeled vehicle, including: a base, a suspension mounted on one side of the base, a rear support mounted on the other side, front wheels mounted on both sides of the suspension, rear wheels mounted on both sides of the rear support, a steering rod mounted on the suspension, the steering rod being able to control the steering of the front wheels, and a backrest assembly mounted on the rear support, the backrest assembly including a cushion, a bent tube, and a fixed seat, the fixed seat being disposed at a certain angle between the base and the rear support, the bent tube being approximately S-shaped, with one end disposed on the fixed seat, and the cushion being disposed on the other end of the bent tube.

[0006] In some embodiments, the bent tube is rotatably mounted on the fixed base.

[0007] In some embodiments, a limiting post is provided on the outer periphery of the end of the bent tube connected to the fixed seat, and a limiting groove is provided on the outer periphery of the fixed seat to cooperate with the limiting post.

[0008] In some embodiments, the suspension includes a main bracket, a steering tube, a spring assembly, and a secondary bracket. The steering rod passes through the steering tube and is connected to one side of the front wheel. The secondary bracket is rotatably disposed on both sides of the main bracket and connected to one side of the front wheel. Spring assemblies are rotatably disposed on both sides of the steering tube to connect with the secondary bracket.

[0009] In some embodiments, a basket is mounted on top of the rear support.

[0010] In some embodiments, a protective bracket is installed at one end of the suspension.

[0011] The beneficial effects of this application are as follows: by setting up a backrest component to support the user's waist, the user's waist injury caused by standing for a long time is reduced; the S-shaped bend tube can avoid the buttocks when the user leans against the backrest, enhancing the stability of the body; at the same time, the bend tube can rotate, which allows the bend tube to rotate with a small range to accommodate the twisting that will occur when turning.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0018] In the embodiments of this application, please refer to Figure 1-2 As shown, this application provides a standing four-wheeled vehicle, mainly including: a base 1, a suspension 2 installed on one side of the base 1, and a rear support 3 installed on the other side. Front wheels 4 are arranged on both sides of the suspension 2, and rear wheels 5 are installed on both sides of the rear support 3. A steering rod 6 is provided on the suspension 2, which can control the steering of the front wheels 4. A backrest assembly 7 is installed on the rear support 3. The backrest assembly 7 includes a cushion 71, a bent tube 72, and a fixed seat 73. The fixed seat 73 is arranged at a certain angle between the base 1 and the rear support 3. The bent tube 72 is approximately S-shaped, and one end of it is arranged on the fixed seat 73. The cushion 71 is arranged at the other end of the bent tube 72.

[0019] Specifically, when a user stands on the base 1, their back will naturally rest against the backrest component 7, which can correct the user's bending habit, provide auxiliary support, and achieve the effect of saving effort. At the same time, the S-shaped bending tube 72 can leave a large distance to prevent contact with the buttocks and cause the user's standing posture to be deformed.

[0020] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0021] Preferably, in order for the cushion 71 to swing in response to the twisting of the user's body, the bent tube 72 is rotatably mounted on the fixed base 73.

[0022] Reference Figure 2 As shown, in order to prevent the bent tube 72 from deviating from the predetermined stroke and rotating to a large extent during rotation, a limit post 721 is provided on the outer periphery of the end of the bent tube 72 connected to the fixed seat 73, and a limit groove 731 that cooperates with the limit post 721 is provided on the outer periphery of the fixed seat 73.

[0023] Reference Figure 3As shown, in order to ensure stable vehicle operation, the suspension 2 includes a main bracket 21, a steering tube 22, a spring assembly 23, and a secondary bracket 24. The steering rod 6 passes through the steering tube 22 and is connected to one side of the front wheel 4. The secondary bracket 24 is rotatably disposed on both sides of the main bracket 21 and is connected to one side of the front wheel 4. The steering tube 22 is rotatably disposed on both sides to connect with the secondary bracket 24. For illustration, there are two sets of secondary brackets 24 placed above and below the main bracket 21 and the front wheel 4, and the spring assembly 23 is connected to the lower secondary bracket 24.

[0024] Reference Figure 1 As shown, a basket 31 is installed on the top of the rear bracket 3 for convenient storage of personal belongings.

[0025] Specifically, in order to prevent the suspension 2 from being damaged by an impact, a protective bracket 25 is installed at one end of the suspension 2.
