Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts technology, specifically to a knob and end cover connection structure for an electric vehicle rotary switch. Background Technology

[0002] With the development of electric vehicle technology, the design requirements for various internal components of electric vehicles are becoming increasingly stringent, especially in terms of ease of operation and cost control. As one of the most common control devices in electric vehicles, the design rationality of the rotary switch directly affects the user experience and the product's market competitiveness. Traditionally, the connection between the knob and end cover of a rotary switch in electric vehicles is achieved through multi-component assembly, such as using screws, clips, and other fasteners to fix the knob and end cover together. While this connection method can meet basic functional requirements, it has the following shortcomings in practical applications:

[0003] 1. Many parts: The traditional method of connecting the knob and the end cap requires additional fasteners, which increases the number of parts in the entire device and increases the assembly complexity in the production process.

[0004] 2. Inconvenient assembly: Because multiple parts need to be worked together, the assembly process of the knob and end cap is relatively complicated, which is not only time-consuming but also prone to assembly errors, affecting the consistency and reliability of the product.

[0005] 3. High cost: The design of multiple components means higher material and labor costs, which will be a considerable expense for mass-produced electric vehicles.

[0006] In view of the above problems, this application proposes a knob-end cover connection structure for an electric vehicle rotary switch, which aims to simplify the connection between the knob and the end cover, improve assembly efficiency, and reduce manufacturing costs, thus providing a more optimized solution for the electric vehicle industry.

[0013] Furthermore, the connecting shell of the mounting groove has a guide slope extending backward.

[0014] The beneficial effects of this utility model are:

[0015] 1. Simplified Structure: By incorporating a connecting step at the top of the knob's connecting post and a limiting step within the end cap's connecting hole, a direct connection between the knob and the end cap is achieved, eliminating the need for additional fasteners. This design significantly reduces the number of parts, simplifies the overall structure, and makes the product more compact and lightweight.

[0016] 2. Easy assembly: The connecting post can be directly inserted into the connecting hole of the end cap, and the limiting step and the limiting step cooperate to achieve limiting and fixing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0027] This utility model provides a connection structure between the knob and the end cap of a rotary switch for an electric vehicle.

[0028] In this embodiment, refer to Figure 1-4 The knob and end cap connection structure of the electric vehicle rotary switch includes a base 1, an end cap 2 and a knob 3. A connecting post 4 is connected inside the knob. A connecting step 5 is provided around the outer ring of the connecting post 4. A connecting hole 6 is provided on the end cap to connect with the connecting post 4. A number of limiting steps 7 are provided at intervals around the inner ring of the connecting hole 6. The limiting steps extend into the connecting hole and have an guide slope 8 on one side of the knob.

[0029] In the above technical solution, the direct connection between the knob and the end cap is achieved through the cooperation of the connecting step and the limiting step, reducing additional fasteners and simplifying the overall structure. The connecting post can be directly inserted into the connecting hole, and the guide of the inclined surface makes the assembly process smoother, reducing assembly time and labor costs. The design of the connecting step and the limiting step ensures a stable connection between the knob and the end cap.

[0030] Specifically, the connection hole has an alignment bevel 9 on one side of the knob.

[0031] The alignment bevel primarily serves as a guide, facilitating the alignment and insertion of the connecting post into the connecting hole. This design helps to quickly align the connecting hole and connecting post during assembly, ensuring the accuracy and consistency of the connection.

[0032] Specifically, the bottom of the connecting step has an insertion ramp 10.

[0033] The insertion bevel works in conjunction with the alignment bevel. The insertion bevel design makes it easier to insert the connecting post into the connecting hole, reducing insertion resistance and improving assembly efficiency. The insertion bevel also reduces friction between the connecting post and the connecting hole, extending the service life of the component.

[0034] Specifically, the knob and connecting post are provided with a keyhole 11.

[0035] The keyhole design allows the rotary switch to be locked with a key, enabling users to easily turn the switch on or off, thus improving ease of use.

[0036] Specifically, the connecting column has connecting housings 12 at both ends that connect to the knob, the connecting housings 12 have hanging grooves 13 on both sides, the knob has a connecting slot 14 for inserting the connecting housing, and the connecting slot has hanging protrusions 15 on both sides that connect to the hanging grooves.

[0037] The design of the mounting groove and mounting boss makes the connection between the connecting shell and the knob more secure, preventing loosening due to vibration or external force. The matching design of the connecting shell and the connecting groove makes the assembly process simpler, reducing assembly time and cost.

[0038] Specifically, the connecting shell of the mounting groove has a guide slope 16 extending backward.

[0039] The guide bevel design makes it easier to insert the connecting housing into the connecting slot, reducing insertion resistance and improving assembly efficiency. The guide bevel also reduces assembly errors caused by improper insertion, ensuring the accuracy and reliability of the connection.

[0040] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
