Description

Technical Field

[0001] This utility model relates to the field of wheel structure technology, specifically to an adjustable directional wheel structure with brakes. Background Technology

[0002] Existing utility vehicles generally consist of a body and several wheels. When transporting goods, these vehicles need to meet certain maneuverability requirements, necessitating a certain height at the wheels. However, excessive wheel height can lead to vehicle instability, failing to meet stability needs. Furthermore, when transporting specific items, utility vehicles require a smooth transport process to minimize vibration, thus necessitating elastic shock absorption in the wheels or body. Additionally, when parked, the vehicles must be able to maintain stability and prevent slippage.

[0003] However, in practical applications, meeting the aforementioned multiple requirements has led to an increase in the structural complexity of utility vehicles, especially around the wheels. This increased complexity makes it difficult to simultaneously address the various issues mentioned above. Furthermore, even after wheel modifications, the complex structure increases wheel wear and tear, hinders maintenance, and increases the complexity and procedures involved in maintenance.

[0004] It is evident that the wheels of current utility vehicles still have room for improvement. Optimization is needed to simplify their structure, enhance their ability to handle various problems, and improve the ease of wheel maintenance. Therefore, a more reasonable technical solution is required to address the technical problems existing in the current technology. Utility Model Content

[0005] To overcome at least one of the aforementioned defects, this utility model proposes an adjustable directional wheel structure with brakes. By designing the wheel structure in a way that facilitates disassembly and assembly, the overall ease of disassembly and assembly is improved. At the same time, the shock-absorbing structure can improve the stability of the vehicle during transportation, and the height can also be adjusted to meet various passability requirements.

[0006] To achieve the above objectives, the directional wheel structure disclosed in this utility model can adopt the following technical solution:

[0007] An adjustable directional wheel structure with brakes includes a connecting cylinder for connecting to a vehicle body, a telescopic cylinder disposed inside the connecting cylinder, an elastic damping structure disposed axially between the connecting cylinder and the telescopic cylinder, and a lifting adjustment structure disposed radially between the connecting cylinder and the telescopic cylinder; a wheel assembly is connected to the lower end of the telescopic cylinder, and a brake assembly is disposed on the wheel assembly.

[0008] The aforementioned directional wheel structure can be quickly connected to and detached from an external vehicle body via a connecting cylinder, offering flexibility and convenience. Simultaneously, the telescopic cylinder, when used in conjunction with the connecting cylinder, filters out external vibrations through its elastic damping structure, ensuring the smoothness of vehicle operation. The telescopic cylinder allows for adjustment of the entire wheel structure height, thereby adjusting the vehicle's passability to meet various road surface requirements. The braking assembly further ensures the vehicle's stability and safety.

[0009] Furthermore, the fit between the connecting cylinder and the telescopic cylinder can be configured in various ways, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: a cavity is formed between the connecting cylinder and the telescopic cylinder, and the elastic damping structure is disposed within the cavity. When adopting the above scheme, the elastic damping structure can be a hydraulic component or a mechanical component, thereby achieving elastic damping.

[0010] Furthermore, the elastic damping structure can take various forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the elastic damping structure includes a spring, with the upper end of the spring abutting against the inner top of the connecting cylinder and the lower end of the spring abutting against the inner bottom of the telescopic cylinder. When using the above scheme, the spring is in a compressed state under normal conditions, providing elastic support to the connecting cylinder and the telescopic cylinder. When there is external pressure, the load on the spring increases, and it is further compressed and deformed.

[0011] Furthermore, in some solutions, the connecting cylinder and the telescopic cylinder can take various forms, and their structures are not uniquely limited. Here, we optimize and propose one feasible option: both the connecting cylinder and the telescopic cylinder are circular cylinders, and an directional structure is provided between them. The directional structure includes a directional groove and a directional block. When the telescopic cylinder slides along the connecting cylinder, the directional block engages within the directional groove and slides along it. Using this solution, the directional groove can be provided on the connecting cylinder, and the directional block on the telescopic cylinder; alternatively, the directional block can be provided on the connecting cylinder, and the directional groove on the telescopic cylinder.

[0012] Furthermore, in other solutions, the connecting cylinder and the telescopic cylinder can also adopt other designs, and their structures are not uniquely limited. Here, we optimize and propose one feasible option: both the connecting cylinder and the telescopic cylinder are polygonal cylinders, elliptical cylinders, or cylinders combining polygons and arcs. When adopting the above solutions, polygonal cylinders, elliptical cylinders, or cylinders combining polygons and arcs can prevent relative circumferential movement, thus eliminating the need for separate directional grooves and directional blocks.

[0013] Furthermore, the lifting and adjusting structure can adopt various schemes, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the lifting and adjusting structure includes several positioning structures set on the telescopic cylinder, and the connecting cylinder is provided with a locking structure that corresponds to and cooperates with the locking structure. When adopting the above scheme, the positioning structure can adopt positioning holes, positioning grooves, positioning teeth, etc.; the locking structure can adopt locking pins, locking strips, etc.

[0014] Furthermore, in some solutions, the locking structure can adopt the following configuration: the positioning structure includes positioning teeth arranged along the length of the telescopic cylinder, and the locking structure includes a locking pin assembly disposed on the surface of the connecting cylinder. When the locking pin assembly moves to the locked position, it engages with the positioning teeth to engage; when the locking pin assembly moves to the unlocked position, it disengages from the positioning teeth. With the above configuration, if the locking pin assembly engages with the positioning teeth, the telescopic cylinder and the connecting cylinder cannot move relative to each other, and the wheel structure lacks shock absorption; if the locking pin assembly disengages from the positioning teeth, the telescopic cylinder and the connecting cylinder can move relative to each other, and the wheel structure provides shock absorption.

[0015] Furthermore, the locking pin assembly can adopt the following scheme: the locking pin assembly includes a pin body, which cooperates with an elastic reset member. The elastic reset member applies an elastic force to the pin body, causing the pin body to move towards the locking position. When the above scheme is adopted, the pin body is pushed to the locking position by the elastic force and remains in the locking position. When the pin body is pulled outward, the pin body compresses the elastic reset member, allowing it to retract to the outside of the connecting housing and remain in the unlocked position. Specifically, the pin body can be kept in the unlocked position through a limiting blocking structure, a snap-fit ​​structure, etc.

[0016] Furthermore, the telescopic cylinder structure can be adjusted when connecting the wheel assembly; its structure is not limited to a single one. Here, an optimization is proposed, and one feasible option is suggested: the lower end of the telescopic cylinder is provided with a bearing seat and a connecting shaft, and the wheel assembly is connected to the connecting shaft. When the above solution is adopted, the bearing seat is connected to the bottom of the telescopic cylinder, and the connecting shaft is fixedly connected to the bearing seat.

[0017] Furthermore, the wheel assembly can take many forms, and its structure is not limited to one. Here, we optimize and propose one feasible option: the wheel assembly includes a wheel seat that mates with the connecting shaft, the wheel seat is connected to the wheel body, and the brake assembly is disposed on the wheel seat and mates with the wheel body.

[0018] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:

[0019] In this invention, by adjusting the directional wheel structure and using the cooperation of the connecting cylinder and the telescopic cylinder, shock absorption of the wheel is achieved, maintaining the stability of the vehicle during driving. The telescopic cylinder is adjustable within the connecting cylinder, enabling adjustment of the wheel height to meet the vehicle's passability requirements. Simultaneously, the directional wheel structure can be flexibly installed and disassembled from the vehicle body, is simple in structure, and easy to use. Attached Figure Description

[0031] The directional wheel structure disclosed in this embodiment can be quickly connected to and disassembled from an external vehicle body via the connecting cylinder 1, offering flexibility and convenience. Simultaneously, the telescopic cylinder 2, when engaged with the connecting cylinder 1, filters out external vibrations through the elastic damping structure 3, ensuring the smoothness of vehicle operation. The telescopic cylinder 2 allows for adjustment of the entire wheel structure height, thereby adjusting the vehicle's passability to meet various road surface requirements. The braking assembly 9 further ensures the vehicle's stability and safety.

[0032] The connection between the connecting cylinder 1 and the telescopic cylinder 2 can be configured in various ways, and its structure is not limited to a single one. Here, we optimize and adopt one feasible option: a cavity is formed between the connecting cylinder 1 and the telescopic cylinder 2, and the elastic damping structure 3 is disposed within the cavity. When adopting the above scheme, the elastic damping structure 3 can be a hydraulic component or a mechanical component, thereby achieving elastic damping.

[0033] The elastic damping structure 3 can take various forms, and its structure is not limited to a single one. Here, we optimize and adopt one feasible option: the elastic damping structure 3 includes a spring, with the upper end of the spring abutting against the inner top of the connecting cylinder 1 and the lower end of the spring abutting against the inner bottom of the telescopic cylinder 2. When the above scheme is adopted, the spring is in a compressed state under normal conditions, providing elastic support force for the connecting cylinder 1 and the telescopic cylinder 2. When there is external pressure, the load on the spring increases, and it is further compressed and deformed.

[0034] Preferably, in this embodiment, the connecting cylinder 1 and the telescopic cylinder 2 can take various forms, and their structures are not limited to a single one. Here, optimization is performed, and one feasible option is adopted: both the connecting cylinder 1 and the telescopic cylinder 2 are circular cylinders, and an directional structure is provided between the connecting cylinder 1 and the telescopic cylinder 2; the directional structure includes a directional groove 101 and a directional block. When the telescopic cylinder 2 slides along the connecting cylinder 1, the directional block engages within the directional groove 101 and slides along the directional groove 101. When adopting the above scheme, the directional groove 101 can be provided on the connecting cylinder 1, and the directional block can be provided on the telescopic cylinder 2; alternatively, the directional block can be provided on the connecting cylinder 1, and the directional groove 101 can be provided on the telescopic cylinder 2.

[0035] The lifting and adjusting structure can adopt various schemes, and its structure is not limited to a single one. Here, we optimize and adopt one feasible option: the lifting and adjusting structure includes several positioning structures set on the telescopic cylinder 2, and the connecting cylinder 1 is provided with a locking structure that corresponds to and cooperates with the locking structure. When adopting the above scheme, the positioning structure can adopt a positioning hole, positioning groove, positioning tooth 11, etc.; the locking structure can adopt a locking pin, locking strip, etc.

[0036] In some solutions, the locking structure can adopt the following configuration: the positioning structure includes positioning teeth 11 arranged along the length of the telescopic cylinder 2, and the locking structure includes a locking pin assembly disposed on the surface of the connecting cylinder 1. When the locking pin assembly moves to the locked position, it engages with the positioning teeth 11 and engages with the positioning teeth 11; when the locking pin assembly moves to the unlocked position, it disengages from the positioning teeth 11. With the above configuration, if the locking pin assembly engages with the positioning teeth 11, the telescopic cylinder 2 and the connecting cylinder 1 cannot move relative to each other, and the wheel structure lacks shock absorption; if the locking pin assembly disengages from the positioning teeth 11, the telescopic cylinder 2 and the connecting cylinder 1 can move relative to each other, and the wheel structure provides shock absorption.

[0037] The locking pin assembly can adopt the following scheme: The locking pin assembly includes a pin 4, which cooperates with an elastic reset member 5. The elastic reset member 5 applies an elastic force to the pin 4, causing the pin 4 to move towards the locking position. When the above scheme is adopted, the pin 4 is pushed to the locking position by the elastic force and remains in the locking position. When the pin 4 is pulled outward, the pin 4 compresses the elastic reset member 5, allowing it to retract to the outside of the connecting housing and remain in the unlocked position. Specifically, the pin 4 can be kept in the unlocked position through a limiting blocking structure, a snap-fit ​​structure, etc.
