Description

Technical Field

[0001] The utility model relates to a highly sealed and waterproof vehicle exterior door switch, belonging to the field of automobile switches. Background Art

[0002] Exterior door switches generally refer to the door handles or switches on the outside of a car that open and close the doors. The design and operation of these switches vary depending on the car model, but most modern cars have a relatively standard design that is easy for users to understand and operate.

[0003] Existing vehicle exterior door switches are prone to problems such as water ingress, which can affect the normal use of the switch in a humid environment with heavy moisture, causing rust and malfunction, affecting normal use by personnel. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and to provide a highly sealed and waterproof vehicle exterior door switch.

[0005] A highly sealed and waterproof vehicle exterior door switch comprises a base, a button mounted on the base, a mounting cavity provided at the bottom of the base, a control component mounted in the mounting cavity, the button comprising a first mounting portion and a pressing portion made of a soft material, the pressing portion being sealedly connected to the first mounting portion; the base comprising a second mounting portion and a triggering portion made of a soft material, the control component comprising a micro switch, a mounting groove for mounting the micro switch being provided in the triggering portion, and the button causing the triggering portion to deform when pressed, triggering the micro switch to send an electrical signal. The pressing portion and triggering portion made of soft material can effectively seal and prevent moisture and dust from entering the internal components, thereby enhancing the waterproof performance of the switch and making it suitable for use in various environments. The use of double-layer soft material makes the button soft and wear-resistant, with good resilience, adaptable to frequent operations, and prevents mechanical fatigue and damage caused by long-term use.

[0006] Preferably, the first and second mounting portions are made of PC+ABS material. PC+ABS combines the advantages of both materials, offering excellent impact resistance and strength, capable of withstanding the various external forces encountered during daily use and enhancing the durability of the switch. Compared to metal, PC+ABS is lighter, helping to reduce the overall weight of the structure. Its excellent electrical insulation properties help prevent short circuits and damage to electronic components, enhancing the safety of the switch.

[0007] Preferably, an inner shell is provided between the base and the button, and the inner shell is in a raised state that matches the button, and the inner shell fits with the button to support the button. The design of the inner shell provides additional support, making the button more stable when pressed, effectively reducing the deformation of the button, and improving the durability and reliability of the button. The fit between the inner shell and the button ensures that the force can be evenly distributed when pressing the button, enhances the trigger sensitivity of the button, and ensures that the user can obtain accurate feedback during operation. The presence of the inner shell can further enhance the sealing effect between the button and the base. Since the raised state of the inner shell can perfectly match the button, the tightness of the connection between the two is enhanced, and the risk of loosening due to vibration or impact is reduced.

[0008] Furthermore, the base and button mounting portions are connected by bolts, effectively improving the torsional strength of the overall structure, enabling it to withstand greater external forces and reducing the risk of damage caused by vibration or impact. This ensures a tight fit between the base and button, reduces potential gaps, further enhances waterproof and dustproof sealing, and protects the safety of internal components.

[0009] Preferably, the control component includes a PCB mounted within the mounting cavity, the microswitch being electrically connected and mounted on the PCB, and the end of the microswitch extending into the mounting slot and abutting against its inner wall. This allows the trigger portion to deform when driven by the button, triggering the microswitch to emit an electrical signal. Direct electrical connection of the microswitch to the PCB ensures stable and reliable signal transmission and reduces the risk of electrical failure due to looseness. The design in which the end of the microswitch extends into the mounting slot and abuts against its inner wall allows deformation of the trigger portion to directly trigger the switch, ensuring a quick and accurate response and enhancing operational sensitivity.

[0010] Preferably, a sealing cover is hermetically connected to the mounting cavity. This sealed connection between the sealing cover and the mounting cavity effectively prevents the intrusion of moisture, dust, and other foreign matter, significantly enhancing the device's waterproof and dustproof capabilities and ensuring the safe operation of internal components. The protection provided by the sealing cover reduces the risk of environmental impact on internal components, thereby reducing maintenance frequency and costs and improving the user experience.

[0011] Furthermore, the sealing cover is formed of a sealant. Using sealant to form the cavity makes sealing and waterproofing more effective. The sealing cover formed using sealant can accurately fill all joints and gaps in the cavity, providing an excellent sealing effect, ensuring that moisture and dust cannot penetrate the interior, and significantly improving waterproof and dustproof capabilities. The sealant has good fluidity and filling capacity, and can easily adapt to complex cavity shapes, ensuring that all edges and corners are fully protected, thereby achieving a comprehensive seal. The sealant has a certain degree of elasticity and toughness, and can maintain good sealing performance under temperature changes or mechanical vibrations, avoiding sealing failure caused by material shrinkage or expansion.

[0012] Preferably, the base is provided with a ventilation groove covered with a breathable membrane. The breathable membrane prevents sudden temperature changes that could cause the switch to freeze. The design of the ventilation groove and breathable membrane allows for air circulation, effectively regulating the internal temperature and preventing rapid temperature rise or fall caused by sudden changes in external temperature, thereby protecting the stability of the switch's internal components. The breathable membrane effectively expels water vapor from the cavity, preventing corrosion or short circuits caused by moisture accumulation, thereby improving the long-term stability and reliability of the device.

[0013] The beneficial effects of this utility model are as follows: The push and trigger parts made of soft material effectively seal the internal components to prevent moisture and dust from entering, enhancing the switch's waterproof performance and making it suitable for use in various environments. The use of double-layered soft material makes the button soft and wear-resistant, with good resilience, adapting to frequent operation and preventing mechanical fatigue and damage caused by prolonged use.

The button 2 comprises a first mounting portion 21 and a push portion 22 made of a soft material, hermetically connected to the first mounting portion 21. The base 1 also comprises a second mounting portion 12 and a trigger portion 13 made of a soft material. The control component 4 includes a microswitch 42, within which a mounting slot 14 for the microswitch 42 is located. Pressing the button 2 causes the trigger portion 13 to deform, triggering the microswitch 42 to transmit an electrical signal. The soft material of the push portion 22 and trigger portion 13 effectively seals the switch from moisture and dust, enhancing its waterproof performance and making it suitable for use in a variety of environments. The double-layered soft material makes the button 2 soft and wear-resistant, with good resilience, adapting to frequent operation and preventing mechanical fatigue and damage from prolonged use.

[0023] The first mounting portion 21 and the second mounting portion 12 are made of PC+ABS material. Combining the advantages of both materials, PC+ABS offers excellent impact resistance and strength, capable of withstanding the various forces encountered during daily use and enhancing the durability of the switch. Compared to metal, PC+ABS is lighter, helping to reduce the overall weight of the structure. Its excellent electrical insulation properties help prevent short circuits and damage to electronic components, enhancing the safety of the switch.

[0024] An inner shell 3 is provided between the base 1 and the button 2. The inner shell 3 is in a raised state that matches the button 2. The inner shell 3 fits with the button 2 and is used to support the button 2. The design of the inner shell 3 provides additional support, making the button 2 more stable when pressed, effectively reducing the deformation of the button 2, and improving the durability and reliability of the button 2. The fit between the inner shell 3 and the button 2 ensures that the force can be evenly distributed when pressing the button 2, enhances the trigger sensitivity of the button 2, and ensures that the user can obtain accurate feedback during operation. The presence of the inner shell 3 can further enhance the sealing effect between the button 2 and the base 1. Since the raised state of the inner shell 3 can perfectly match the button 2, the tightness of the connection between the two is enhanced, and the risk of loosening due to vibration or impact is reduced.

[0025] The mounting portions of the base 1 and button 2 are connected by bolts 15, effectively increasing the torsional strength of the overall structure, enabling it to withstand greater external forces and reducing the risk of damage from vibration or impact. This ensures a tight fit between the base 1 and button 2, reduces potential gaps, further enhances waterproof and dustproof sealing, and protects the safety of internal components.

[0026] The control component 4 includes a PCB 41 mounted within the mounting cavity 11. The microswitch 42 is electrically connected to the PCB 41.

The direct electrical connection of the microswitch 42 to the PCB 41 ensures stable and reliable signal transmission and reduces the risk of electrical failure due to looseness. The design of the microswitch 42, with the end extending into the mounting slot 14 and abutting against its inner wall, allows deformation of the trigger portion 13 to directly trigger the switch, ensuring a quick and accurate response and enhancing operational sensitivity.

[0027] A sealing cover 5 is hermetically connected to the mounting cavity 11. This seal effectively prevents the intrusion of moisture, dust, and other foreign matter, significantly enhancing the device's waterproof and dustproof capabilities and ensuring the safe operation of internal components. The protection provided by the sealing cover 5 reduces the risk of environmental impact on internal components, thereby reducing maintenance frequency and costs and improving the user experience.

[0028] The sealing cover 5 is formed of a sealant. Using sealant to form the cavity provides a more effective seal and waterproofing. The sealant can precisely fill all joints and gaps in the cavity, providing an excellent seal, preventing moisture and dust from entering the cavity and significantly improving waterproof and dustproofing. The sealant has excellent fluidity and filling capacity, easily adapting to complex cavity shapes and ensuring that every edge and corner is fully protected, thus achieving a comprehensive seal. The sealant has a certain degree of elasticity and toughness, enabling it to maintain good sealing performance despite temperature fluctuations or mechanical vibrations, preventing seal failure due to material shrinkage or expansion.

[0029] The base 1 is provided with a ventilation groove 6, which is covered with a breathable membrane 61. This membrane prevents sudden temperature changes that could cause the switch to freeze. The design of the ventilation groove 6 and membrane 61 allows for air circulation, effectively regulating the internal temperature and preventing rapid temperature rise or fall caused by sudden external temperature changes, thereby protecting the stability of the switch's internal components.
