Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a quick-release steering wheel connection structure for connecting the steering wheel and the steering column. Background Technology

[0002] With the development of the automotive industry, the functions and application scenarios of vehicles are becoming increasingly diversified. In certain specific situations, such as when autonomous vehicles require temporary human intervention, or when vehicles are undergoing maintenance or personalized modifications, users or technicians wish to be able to easily and quickly remove and install steering wheels.

[0003] However, traditional steering wheel mounting methods typically involve directly fixing the steering wheel to the splined shaft of the steering column using bolts or nuts. While this method is reliable, disassembling and reinstalling the steering wheel is cumbersome, usually requiring specialized tools such as wrenches. This not only consumes a significant amount of time and effort but also can cause wear and tear on the connecting components due to repeated disassembly and reassembly. The inefficiency and inconvenience of traditional methods are particularly pronounced in situations requiring frequent disassembly and reassembly, failing to meet the flexibility and convenience demands of modern automobiles.

[0004] Therefore, developing a connection structure that enables quick, convenient, and reliable disassembly and assembly of the steering wheel has significant practical implications and application value. Summary of the Invention

[0005] Purpose of the invention: The purpose of this utility model is to address the shortcomings of the existing technology by providing a quick-release steering wheel connection structure to achieve quick and convenient disassembly and installation of the steering wheel.

[0006] Technical solution: This utility model relates to a quick-release steering wheel connection structure for detachably connecting the steering column and the steering wheel. The structure includes a quick-release mechanism disposed between the steering column and the steering wheel, serving as a connection interface between the two.

[0007] The quick-release structure includes a lower base, an upper base, and a positioning mechanism disposed between the lower base and the upper base. The lower base is connected to the steering column, and the upper base is connected to the steering wheel. The lower base and the upper base are detachably connected by a connecting mechanism to allow for quick disassembly and installation of the steering wheel relative to the steering column. The positioning mechanism is used to achieve precise positioning of the lower base and the upper base when they are connected. The key function of this positioning mechanism is to ensure a precise relative positional relationship between the lower base and the upper base when they are connected by the connecting mechanism. Specifically, it ensures coaxiality between them and prevents relative rotation, thereby guaranteeing the stability and handling precision of the steering wheel after installation.

[0008] Furthermore, the positioning mechanism employs ball bearing positioning.

[0009] Furthermore, the lower base and the upper base form a standard quick-release assembly.

[0010] Furthermore, the lower base is connected to the steering column via a spline connection.

[0011] Furthermore, the upper base is fixed to the bottom of the steering wheel by screws.

[0012] Beneficial effects: Compared with the prior art, the advantages of this utility model are: convenient and efficient disassembly and assembly: by adopting a quick-release structure, the disassembly and installation process of the steering wheel becomes extremely simple and quick, without complicated steps and long-term operation.

[0013] No special tools required: The quick-release mechanism is usually designed to be operated by hand or using a simple integrated release device, saving the trouble of finding and using professional disassembly and assembly tools.

[0014] Saves time and effort: Significantly reduces the time required to disassemble and assemble the steering wheel, reducing the workload of the operator.

[0015] Precise and stable positioning: The positioning mechanism (especially when using ball bearing positioning) ensures the coaxiality and angular stability of the steering wheel after installation, preventing loosening or play, and guaranteeing the precision and safety of steering operations.

[0016] Increased flexibility: This makes it possible to quickly remove or replace the steering wheel as needed in various scenarios such as autonomous driving, vehicle maintenance, and racing car modification, thereby improving the flexibility and convenience of vehicle use.

[0017] High reliability: By selecting appropriate (such as standard) quick-release parts and combining them with reliable fixing methods (such as splines, nuts, screws), the overall strength and durability of the connection structure are guaranteed. Attached Figure Description

[0020] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings, but the protection scope of this utility model is not limited to the described embodiments.

[0021] Example 1: Refer to Figure 1The quick-release steering wheel connection structure shown is used to detachably connect the steering wheel 2 to the vehicle's steering column 1. Its core is a quick-release structure set between the top of the steering column 1 and the bottom of the steering wheel 2.

[0022] The quick-release structure mainly consists of two parts: a lower base 4 and an upper base 3. The lower base 4 is responsible for connecting to the steering column 1. In this embodiment, the lower end of the lower base 4 is provided with an internal spline, which mates with the external spline at the upper end of the steering column 1 to form a spline connection for transmitting steering torque. At the same time, the upper end of the steering column 1 is threaded, and a nut passes through the center hole of the lower base 4 and is tightened onto the thread to firmly fix the lower base 4 axially to the top of the steering column 1.

[0023] The upper base 3 is responsible for connecting to the steering wheel 2. In this embodiment, the upper end face of the upper base 3 is fixedly installed on the bottom of the steering wheel 2 by several screws.

[0024] The lower base 4 and the upper base 3 are connected and separated through a quick-release structure with an internal connecting and positioning mechanism. The connecting mechanism allows the upper base to be quickly snapped into or locked onto the lower base 4, and can be quickly unlocked by operating a release device, thereby separating the upper base 3 (and steering wheel 2) from the lower base 4 (and steering column 1).

[0025] To ensure the stability and accuracy of the steering wheel 2 after installation, a positioning mechanism is provided on the mating surfaces of the lower base 4 and the upper base 3. This positioning mechanism ensures that when the two are engaged, the upper base 3 has precise coaxiality relative to the lower base 4 and that relative rotation does not occur. In this embodiment, the positioning mechanism preferably uses ball bearing positioning. For example, several precision-machined recesses can be provided on the end face of one base (such as the lower base 4), and spring-loaded balls can be provided at corresponding positions on the other base (such as the upper base 3). When the two are aligned and pressed together, the balls embed into the recesses, achieving high-precision center positioning and circumferential locking.

[0026] In practical applications, this quick-release structure can be designed as a "standard quick-release component" that conforms to specific industry practices or standards. This allows for the use of mature designs to ensure performance and compatibility.

[0027] When removing the steering wheel 2, the user only needs to operate the release device on the quick-release structure to remove the upper base 3 together with the steering wheel 2 from the lower base 4. During installation, align the upper base 3 with the lower base 4 and gently push it in. Once the positioning mechanism is aligned and the connecting mechanism is engaged and locked, the steering wheel 2 is securely and precisely installed in place. The entire process is quick, simple, and requires no tools.

[0028] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
