Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a bistable switch assembly for vehicles. Background Technology

[0002] With the rapid development of the logistics industry, the demand for commercial vehicles is increasing, and the requirements for electrical functions and driving comfort are also rising. Currently, commercial vehicle power switches mainly come in two types: manual power switches and electromagnetic main power switches. Manual power switches control the circuit through manual operation; electromagnetic main power switches control the circuit through electromagnetic principles. Compared to manual power switches, electromagnetic main power switches have advantages such as faster response speed and immunity to mechanical wear. However, in many application scenarios of commercial vehicles, a single two-state configuration may not be flexible or stable enough. For example, in some advanced electronic devices and automated systems, a switching device capable of switching between two stable states is needed to adapt to more complex operational requirements.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0022] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0023] Example 1:

[0024] A bistable switch assembly for vehicles includes a switch body 1, within which an electromagnetic control assembly is housed. An upper housing 2 is located at the upper end of the switch body 1, with a first nut 3 and a second nut 4 at its upper end. A first conductive washer 5 is positioned between the first nut 3 and the upper housing 2, and a second conductive washer 6 is positioned between the second nut 4 and the upper housing 2. The first nut 3 is an M10 nut, and the second nut 4 is an M12 nut. Both conductive washers are tin-plated. A pin 7, also tin-plated, is located on the side of the upper housing 2. Like an electromagnetic power switch, the bistable power switch automatically connects and disconnects the circuit. However, unlike an electromagnetic power switch, the normally closed or normally open state of the bistable power switch relies entirely on the action of a permanent magnet. The switching state transition is achieved through continuous high and low level signals. When the switch contacts need to be open or closed, a high (low) DC level signal input triggers the switch, and the microcontroller controls the coil's on / off state, instantly completing the open / close state transition of the relay. When the contacts are in the closed holding state, the coil does not need to be energized anymore; the magnetic force of the permanent magnet is enough to maintain the switch state.

[0025] The automotive bistable switch assembly boasts excellent conductivity and stable operation, relying on a combination of permanent magnets and electromagnetic principles. When the electromagnetic coil is energized, the generated magnetic force drives the armature to move, causing the contacts to close / open, thereby connecting / disconnecting the load circuit. Even when the coil is de-energized, the contacts remain in the closed / open state due to the attraction of the permanent magnet, achieving low power consumption and low temperature rise characteristics. The upper housing 2 is fixed by the first nut 3 and the second nut 4, and a good electrical connection is achieved through the first conductive washer 5 and the second conductive washer 6, effectively improving the switch's conductivity efficiency. The pin 7 located on the side of the upper housing 2 is designed for easy connection with other electrical components, ensuring smooth and stable circuit operation, thus realizing reliable switching and control of functions such as starting, stopping, or changing operating states.

[0026] The switch body 1 and the upper housing 2 are connected by tubular rivets 8, and the surface of the tubular rivets 8 is tin-plated.

[0027] In this embodiment, a first spring washer 9 is provided between the first nut 3 and the first conductive washer 5, and a second spring washer 10 is provided between the second nut 4 and the second conductive washer 6. The spring washer can not only effectively increase the tightness of the contact surface and prevent loosening and poor contact, but also play a certain role in shock absorption and buffering, ensuring that the connection part maintains stability and reliability when subjected to external force, thereby improving the electrical connection performance and durability of the entire device.

[0028] In this embodiment, the first nut 3 is provided with an M10 protective cap 11, and the second nut 4 is provided with an M12 protective cap 12. The two protective caps are used to protect the nuts that are used in the same way. The protective caps are both made of silicone rubber and are different colors for easy distinction.

[0029] In this embodiment, a protective cover 13 is provided on the outside of the upper housing 2, which protects the upper housing 2 and the switch assembly, ensuring that the protection level reaches IP67 / IP6K9K.

[0030] In this embodiment, the electromagnetic control assembly includes a coil assembly 14, within which a spindle 15 is provided. The spindle 15 is made of stainless steel and has a nickel-plated surface. One end of the spindle 15 is provided with an upper compression spring 16, and the other end is provided with a lower compression spring 17. A conductive plate assembly 18 is provided outside the spindle 15. A plastic bushing 19 and a plastic washer 20 are provided between the conductive plate assembly 18 and the spindle 15. A magnetic post 21 is provided between the spindle 15 and the coil assembly 14. A first magnetic plate 22 and a second magnetic plate 23 are provided outside the coil assembly 14. A strong magnet 24 is provided between the first magnetic plate 22 and the second magnetic plate 23. The strong magnet 24 is made of neodymium iron boron. The magnetic column 21, the first magnetic plate 22 and the second magnetic plate 23 are all made of DT4. This significantly improves the magnetic conductivity and uniformity of the magnetic force distribution of the overall component, thereby greatly enhancing the magnetic force transmission efficiency. This makes the equipment run more stably during operation and reduces energy loss and heat generation. The coil assembly 14 is provided with a shock-absorbing washer 25 on the outside. The shock-absorbing washer 25 is made of silicone rubber and has a shock-absorbing and buffering effect.

[0031] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
