Abstract
Description
Technical Field
[0001] This utility model relates to the field of touch switch technology, specifically a touch switch. Background Technology
[0002] In the field of new energy vehicles, as the level of intelligence and integration of vehicles continues to increase, the performance and design of various control components inside the vehicle are becoming increasingly critical.
[0003] Traditional touch switches have relatively simple functions. The air conditioning control switch and the evaporator temperature control panel are independent of each other, and are manufactured and assembled as separate components. This separate design increases the number of parts in the automobile production process, which not only increases the complexity and difficulty of assembly, but also significantly increases the production and manufacturing costs, which is not conducive to the cost control competitiveness of new energy vehicles. From the perspective of user experience, the air conditioning and related controls in the past mostly adopted manual adjustment methods, such as adjusting functions by rotating buttons or toggle switches. This manual adjustment method is cumbersome, requires users to spend time to operate accurately, and the adjustment feel is not good, which fails to meet users' pursuit of convenient and comfortable operation experience. At the same time, the mechanical manual adjustment components are prone to failure due to wear and loosening during long-term use, affecting normal use. With the increasing demand for intelligent interconnection, traditional manual adjustment switches face many difficulties in adapting to the remote start control logic of air conditioning due to their mechanical position. The limitations of the mechanical structure make it difficult to accurately feed back and execute remote control signals, which cannot achieve flexible and accurate remote control of the air conditioning system and cannot meet the needs of the intelligent development of new energy vehicles. Therefore, we propose a touch switch. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a touch switch that offers a good touch operation experience and is compatible with remote control logic. This solves the problems of traditional touch switches having limited functionality, and the separate design of the air conditioning control switch and the evaporator temperature control panel, which are manufactured and assembled as separate components. This separate design increases the number of parts in automobile production, not only increasing the complexity and difficulty of assembly but also significantly raising manufacturing costs, hindering the cost competitiveness of new energy vehicles. From an operational perspective, previous air conditioning and related controls mostly used manual adjustment methods, such as rotating buttons or toggle switches. While manual adjustment methods offer functional adjustments, they are cumbersome to operate, requiring users to spend time on precise operation. Furthermore, the tactile feedback is unsatisfactory, failing to meet users' demands for convenient and comfortable operation. Additionally, the mechanical manual adjustment components are prone to malfunction due to wear and loosening during long-term use, affecting normal operation. With the increasing demand for intelligent connectivity, traditional manual switches, due to their mechanical position, face numerous difficulties in adapting to remote air conditioning control logic. The limitations of the mechanical structure make it difficult to accurately receive and execute remote control signals, hindering flexible and accurate remote control of the air conditioning system and failing to meet the needs of intelligent development in new energy vehicles.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a touch switch, including a bottom shell, with a pair of plugs fixedly connected to both sides of the bottom of the bottom cavity of the bottom shell, a circuit board inserted into the top of the pair of plugs, a rotating shaft provided in the inner cavity of the circuit board, a bracket provided on the outer side of the circuit board, the bottom of the bracket inserted into the bottom shell, a capacitor film provided on the top of the bracket, a touch panel provided on the top of the capacitor film, a light guide ring provided on one side of the touch panel, the bottom of the light guide ring inserted into the rotating shaft, an aluminum knob provided on the outer surface of the light guide ring, a top cover provided on the top of the aluminum knob, and one side of the capacitor film inserted into the circuit board via a connector plug.
[0006] Preferably, double-sided adhesive is adhered to both sides of the top of the bracket, and the top of the double-sided adhesive is adhered to the touch panel.
[0007] Preferably, the touch panel, the capacitive film, and the bracket all have movable holes at their central axes, and the circuit board has a movable groove at its central axis.
[0008] Preferably, a buckle is fixedly connected to the outer side of the bottom shell, and a limiting groove is opened on both sides of the bottom shell. A vertical rod is inserted into the inner cavity of the limiting groove, and the top of the vertical rod is fixedly connected to the bracket.
[0009] Preferably, support tubes are fixedly connected to the four corners of the bottom of the inner cavity of the bottom shell, and threaded holes are opened at the bottom of the rotating shaft and the bracket, and bolts are threadedly connected to the inner cavity of the threaded holes.
[0010] Compared with the prior art, the present invention provides a touch switch with the following advantages:
[0011] When a user operates the touch panel, the capacitive film beneath it serves as the core sensing component. Utilizing the characteristics of the human body's electric field, it changes its capacitance value the instant a finger approaches or touches the surface. Thanks to the structural design of the touch panel, capacitive film, movable holes on the top of the support, and movable slots on the top of the circuit board, the capacitive film is stably positioned, ensuring accurate sensing of touch actions. The resulting capacitance change signal is smoothly transmitted to the circuit board below. The circuit board achieves stable electrical connection and physical support through plug-in connectors on both sides of the bottom of the inner cavity of the base. After receiving the signal from the capacitive film, the circuit system on the circuit board quickly processes, analyzes, and converts it. The rotating shaft within the circuit board not only provides mechanical support but may also participate in signal transmission, passing the processed signal to subsequent control modules. For example, when a user touches or rotates an aluminum knob, the rotating shaft, plugged into the bottom of the light guide ring, converts the mechanical action into an electrical signal, which is transmitted to the circuit board. After processing, the signal is sent to devices such as air conditioning systems to achieve functions such as temperature regulation and fan speed control. In terms of structural design… This touch switch integrates the traditional independent air conditioning control switch with the evaporation temperature control panel, reducing the number of automotive parts. The buckles and limiting grooves on the outer side of the base, the internal support tubes, and the insertion of the bracket bottom into the base and the cooperation between the vertical rod and the limiting groove ensure precise positioning and stable assembly of each component. This significantly reduces assembly complexity and difficulty, effectively controls production costs, and enhances the cost competitiveness of new energy vehicles. From an operational perspective, compared to traditional manual adjustment switches, this touch switch is more convenient. Users can easily adjust functions by simply touching or rotating the aluminum knob, avoiding malfunctions caused by wear and loosening of traditional mechanical structures, resulting in a more comfortable operating feel. Furthermore, by eliminating the mechanical position limitations of traditional manual adjustment switches, this touch switch is better suited to remote air conditioning control logic. When a remote control signal is received, the circuit board can accurately process and execute the instruction, precisely feeding the control signal back to the air conditioning system, achieving flexible and accurate remote control, aligning with the intelligent development trend of new energy vehicles.

[0019] Double-sided adhesive tape 6 is attached to both sides of the top of the bracket 4, and the top of the double-sided adhesive tape 6 is attached to the touch panel 7.
[0020] Movable holes are provided at the central axis of the top of the touch panel 7, the capacitive film 5, and the bracket 4, and a movable groove is provided at the central axis of the top of the circuit board 2.
[0021] The outer side of the bottom shell 1 is fixedly connected with a buckle. Limiting grooves are opened on both sides of the bottom shell 1, and a vertical rod is inserted into the inner cavity of the limiting groove. The top of the vertical rod is fixedly connected to the bracket 4.
[0022] Support tubes are fixedly connected to the four corners of the bottom of the inner cavity of the bottom shell 1. Threaded holes are opened at the bottom of the rotating shaft 3 and the bracket 4, and bolts are threadedly connected to the inner cavity of the threaded holes.
[0023] Working Principle: When a user operates the touch panel 7, the capacitive film 5 beneath the touch panel 7 acts as the core sensing component. Utilizing the characteristics of the human body's electric field, it changes its capacitance value the instant a finger approaches or touches the surface. Thanks to the structural design of the touch panel 7, capacitive film 5, the movable holes on the top of the bracket 4, and the movable slot on the top of the circuit board 2, the capacitive film 5 is stably positioned, ensuring accurate sensing of touch actions. The resulting capacitance change signal is also smoothly transmitted to the circuit board 2 below. The circuit board 2 achieves stable electrical connection and physical support through the plug-in 11 on both sides of the bottom of the inner cavity of the bottom shell 1. After receiving the signal from the capacitive film 5, the circuit system on the circuit board 2 quickly processes, analyzes, and converts it. The rotating shaft 3 inside the circuit board 2 not only provides mechanical support but may also participate in signal transmission, transmitting the processed signal to the subsequent control module. When the user touches or rotates the aluminum knob 9, the rotating shaft 3, which is inserted into the bottom of the light guide ring 8, converts the mechanical action into an electrical signal, which is transmitted to the circuit board 2. After processing, the signal is sent to equipment such as the air conditioning system to achieve functions such as temperature regulation and fan speed control. In terms of structural design, this touch switch integrates the traditional independent air conditioning control switch with the evaporation temperature control panel, reducing the number of automotive parts. The buckles and limiting grooves on the outside of the bottom shell 1, the internal support tubes, and the insertion of the bottom of the bracket 4 into the bottom shell 1, and the cooperation between the vertical rod and the limiting groove, achieve precise positioning and stable assembly of each component, significantly reducing assembly complexity and difficulty, effectively controlling production costs, and enhancing the cost competitiveness of new energy vehicles. From an operational perspective, compared to traditional manual adjustment switches, this touch switch is more convenient to operate. Users only need to touch or rotate the aluminum knob 9 to complete the function adjustment, avoiding the failure problems caused by wear and loosening of traditional mechanical structures, and bringing a more comfortable operating feel. At the same time, because it is free from the mechanical position limitations of traditional manual adjustment switches, this touch switch can better adapt to the remote air conditioning start control logic. When a remote control signal is received, the circuit board 2 can accurately process and execute the instruction, accurately feeding the control signal back to the air conditioning system, realizing flexible and accurate remote control, which is in line with the intelligent development trend of new energy vehicles.
