Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a highly waterproof intelligent automobile micro switch. Background Art

[0002] Nowadays, new energy vehicles are developing rapidly, and various new intelligent and green technological configurations are constantly emerging, which are constantly refreshing the inherent concept of traditional fuel vehicles; the opening and closing of doors of traditional fuel vehicles are mostly controlled by external door handles. In order to reduce driving wind resistance and optimize the technological shape of the whole vehicle, new energy vehicles often cancel external handles (or hide them), and set electric door opening and closing micro switches on the A and B pillars; the so-called vehicle micro switch can control the opening and closing of the door, and uses LIN signals to control the color and brightness of the backlight symbol; when the key is within 10m of the vehicle, the white light of the button backlight remains on; after the door is unlocked, the green light of the button backlight remains on; when opening and closing the door normally, the green light flashes (frequency 1S once), and the green light remains on after the door opening and closing is completed; when a fault occurs during the door opening and closing process and cannot be completed, the red light flashes (frequency 1S once); after locking the car, the white light of the button backlight flashes (frequency 1S once, flashing three times and then extinguishing).

[0003] Since the micro switch is installed on the B-pillar trim of the vehicle body, it is an exterior trim and is often exposed to harsh environments such as rain and sun. Water may enter the switch, causing it to fail, or water may enter the switch installation gap and flow into the vehicle, affecting the air tightness of the vehicle body. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In one embodiment, see Figure 1-Figure 5 A highly waterproof smart micro switch for a car includes a base 8, a PCBA 7 is arranged on the upper surface of the base 8, the PCBA 7 is covered with a conductive rubber 6, a button seat 3 is clamped on the top of the base 8, a balance bar 4 and a pressure block 5 that cooperate with the conductive rubber 6 are arranged on the button seat 3, and a button 2 is arranged on the top of the button seat 3. A wiring harness assembly 9 is arranged at the bottom of the base 8. The wiring harness assembly 9 is installed on the upper side of the base 8 after being welded with the PCBA 7, the conductive rubber 6 is installed on the upper side of the PCBA 7, the pressure block 5 is installed on the upper side of the conductive rubber 6, the balance bar 4 is installed on the lower side of the button seat 3, the button seat 3 is installed on the upper side of the base 8, the button 2 is installed on the upper side of the button seat 3, and the housing 1 is installed on the upper side of the base 8. The button 2 is clamped and fixed with the button seat 3, and the button seat 3 is arranged on the rib groove inside the base 8. When the button 2 is pressed down, it drives the button seat 3 to press the conductive rubber 6 and the micro switch 71, and the switch is turned on. The balance bar 4 is installed on the button seat 3 to ensure that the left and right ends of the button 2 are pressed down at the same time. Prevent the switch contact from being unreliable due to pressing one end of button 2.

[0022] In one case of this embodiment, the conductive rubber 6 is installed on PCBA7 and fixed by the pressing block 5. The conductive rubber 6 and the micro switch 71 are compressed, and the contact touches the gold finger of the conductive disk on PCBA7, and the switch is turned on. When the external force is removed, the conductive rubber 6 rebounds to provide the axial force, and the contact is reset under the action of the conductive rubber 6's own resilience, and the switch is disconnected. The elastic force of the conductive rubber 6 provides the feel and operating force. The PCBA7 is arranged with a conductive disk corresponding to the conductive rubber 6, as well as electrical components such as RGB three-color lights 73 and chips 72, which provide working instructions and backlight for the switch. The PCBA7 is welded with a wiring harness assembly, which is convenient for connecting with the vehicle body wiring harness sheath to achieve functional output. The chip 72 and the RGB three-color light 73 are arranged on the PCBA7. The chip 72 receives the LIN signal sent by the vehicle body control system, thereby controlling the color and brightness of the RGB three-color light 73 to complete a variety of intelligent interactions with the vehicle body system.

[0023] In one case of this embodiment, the button seat 3 is wrapped with a shell 1 that matches the base 8. The base 8 is installed with the shell 1, pressing the soft rubber flange on the button 2 and wrapping the PCBA 7 to achieve the closure and protection of the switch. Epoxy resin glue is poured into the wiring harness port of the base 8 to prevent water from entering the switch from the wiring harness port of the base 8. The connector hook on the wiring harness assembly 9 is connected to the vehicle body wire speed sheath to prevent the wiring harness sheath from falling out.

[0024] In one case of this embodiment, the shell 1 is made of PC+ABS and TPE double-color injection molding, and the button 2 is made of PC black transparent and TPE over-molded. The shell 1 is made of PC+ABS and TPE double-color injection molding, PC+ABS is a hard rubber body, which plays a supporting and fixing role, and TPE soft rubber is interference-sealed with the B-pillar trim of the vehicle body to prevent water from entering from the installation gap of the switch. The button 2 is made of PC black transparent and TPE over-molded, PC is a hard rubber body, the inner surface is sprayed with black paint and laser engraved with symbols, which plays an indication and beautiful appearance effect, and the outer surface is sprayed with UV transparent paint, which plays an exterior decoration protection effect and prevents the button surface from cracking, peeling and other problems; TPE soft rubber and hard rubber body are integrally injected, which effectively prevents water from entering the switch from the side of button 2, and TPE soft rubber is an elastic structure, which does not affect the rebound effect of button 2.

[0025] The utility model is suitable for a highly waterproof intelligent vehicle micro switch. The switch structure is simple and has low manufacturing cost. It can meet the IP6K7 high waterproof performance, and the signal indication on the button surface interacts intelligently with the vehicle body control system. The button seat 3 combines motion guidance and light guiding functions, reduces light guide column parts, simplifies the production process, improves production efficiency, reduces labor costs, and has lower costs while achieving the same functions.
