Description
Technical Field
[0001] This utility model relates to the field of switch technology, and in particular to a novel tactile switch assembly. Background Technology
[0002] Electric vehicles typically have switch assemblies on the handlebars on both sides. These assemblies are connected to the circuitry to enable multiple control functions, such as horn warning, speed adjustment, power switch, and high / low beam headlight adjustment. The switches are usually directly mounted on the switch assembly. Switch malfunction is a common problem for users during the use of electric vehicles.
[0003] Chinese Patent Announcement No.: CN 217294749 U, Announcement Date: August 26, 2022. This utility model discloses a switch assembly on an electric vehicle handlebar, including a handlebar. The handlebar is equipped with a switch assembly, which includes a rocker switch, a tactile switch, and a push-gear switch. The handle includes a housing, a mounting cavity within the housing, and a base plate located within the mounting cavity for mounting the switch assembly. The base plate is detachably connected to the housing. The housing includes a first housing and a second housing, which are detachably connected. A first mounting seat is provided in the mounting cavity between the rocker switch and the base plate, and the first mounting seat is detachably connected to the base plate. A third mounting seat is provided in the mounting cavity between the tactile switch and the base plate, and the third mounting seat is detachably connected to the second housing. A second mounting seat is provided in the mounting cavity between the push-gear switch and the base plate, and the second mounting seat is detachably connected to the base plate. The shortcomings of this technical solution are: 1. The tactile switch and the mounting base are installed separately from the housing, resulting in low assembly efficiency and difficult maintenance; 2. The mounting base is fixed by limiting the position with a base plate on one side, which results in low fixing strength for the mounting base and the tactile switch, making it easy for the switch to malfunction later and affecting the stability of the handle; 3. The poor sealing of the two housings makes it easy for water to enter and damage the circuit.
[0004] In summary, the switch components on the handle have shortcomings such as low assembly efficiency, difficulty in maintenance and poor assembly stability, as well as poor waterproofing leading to easy failure. Utility Model Content
[0005] This invention aims to overcome the shortcomings of existing switch assemblies on handles, such as low assembly efficiency, difficulty in maintenance, poor assembly stability leading to easy failure, and poor waterproofing. It provides a novel tactile switch assembly that achieves modular assembly, improves assembly efficiency, facilitates later maintenance, and enhances assembly stability and waterproofing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A novel tactile switch assembly, comprising Housing 1, housing 2 is sealed to housing 1, and handle pre-drilled holes are provided on the end faces of housing 1 and housing 2; The button hole is located on the housing and is connected to the signal button and the horn button. The mounting bracket is placed inside the housing and has several switching elements embedded in it. The horn key and signal key are movably connected to the switching elements. The locking bracket is snapped into the mounting bracket. The housing is connected to several fixing posts. The locking bracket is bolted to the fixing posts. The switching element is placed between the mounting bracket and the locking bracket. Both the mounting bracket and the locking bracket are connected to positioning components. The base plate is supported, and the shell is connected to several fixed columns. The locking bracket abuts against the base plate and the fixed columns. The shell is bolted to the base plate and the fixed columns.
[0007] Housing 1 and Housing 2 are bolted together to form a single unit, and the connection is sealed to improve waterproofing and protect the internal circuitry. The end face after assembly has a pre-drilled hole for mounting a handle. Several button holes are provided on the side of Housing 1 for mounting horn buttons and signal buttons. The mounting bracket is placed inside Housing 1 and works with the locking bracket to limit the switching element. The circuit is connected and the switch is turned on by contacting the switching element with the signal button or horn button. The locking bracket and mounting bracket snap together to pre-install the switching element during assembly, initially fixing the switching element. Then, the locking bracket, along with the fixing post and bolts, further secures the switching element to the housing. This results in a more compact structure, and the switching element, clamped and fixed from both sides, is completely confined within the housing to prevent shaking under external vibrations that could affect circuit continuity. The positioning component assists in the assembly accuracy and efficiency of the locking bracket and mounting bracket, enabling efficient assembly with rapid pre-assembly and secondary locking of components, facilitating later disassembly and maintenance, and ensuring high-strength stability of the circuit. The support frame connects within the housing and works with the fixing post to support and position the locking bracket, allowing for quick docking of the mounting bracket, locking bracket, and switching element assembly. The fixing post is then bolted to the housing to quickly and stably fix the switching element to the housing. This achieves modular assembly of the tactile switch assembly, improving assembly efficiency and facilitating later maintenance; it also provides waterproof sealing, enhanced assembly stability to prevent open-circuit faults, and a highly precise and compact structure between components.
[0008] Preferably, the mounting bracket has through holes, and the switching element is electrically connected to a PCB board. One side of the PCB board abuts against the mounting bracket, and the other side abuts against a locking bracket. The switching element is inserted into the through holes. The mounting bracket is connected to a limit plate, and the limit plate is connected to a limit post. Both the signal key and the horn key have a socket, and the limit post is inserted into the socket. Through holes are formed on the surface of the mounting bracket, allowing the contact portion of the switching element to extend out of the through holes and face the signal key and horn key for pressing. The limit plate connected to the mounting bracket ensures that the signal key and horn key are inserted along the limit plate and that the limit post is inserted into the socket. The limit post and socket are circular in shape, allowing the signal key to be pressed with the limit post as a fulcrum. This improves the stability of component assembly and circuit connectivity.
[0009] Preferably, the locking bracket is connected to a snap plate with snap holes, and the mounting bracket is connected to a snap block, which engages with the snap plate through the snap holes. The locking bracket is connected to a snap plate with snap blocks that fit the snap blocks, allowing for quick connection between the mounting bracket and the locking bracket by the snap blocks entering the snap holes of the snap plate during assembly. This achieves the effect of rapid, stable, modular pre-assembly of the locking bracket and the mounting bracket.
[0010] Preferably, several buckle plates are provided, arranged near the edge of the end face of the locking bracket, with the buckle plates on both sides arranged in a mirror image. Multiple buckle plates are provided, with the number of buckle blocks corresponding to the number of buckle plates. The buckle plates are arranged symmetrically and evenly on both sides near the edge of the end face of the locking bracket to prevent interference with subsequent bolt connections and to ensure more even overall force application. This achieves the effect of improving the rationality of the structural layout of the assembly.
[0011] Preferably, the positioning component includes a positioning protrusion, and the side of the mounting bracket has a mating groove. The positioning protrusion connects to the side of the locking bracket, and the positioning protrusion engages with the mating groove. When the mounting bracket and the locking bracket are mated, the positioning protrusion engages with the mating groove, thereby increasing the tightness of the connection and achieving the effect of enhancing the connection tightness.
[0012] Preferably, the positioning component includes a positioning protrusion connected to the end face of housing one, and housing two has a positioning groove that engages with the positioning protrusion. Housing one has several positioning bosses on its end face, and housing two has correspondingly sized and positioned positioning grooves to ensure precise positioning and prevent misalignment when housing one and housing two are joined. Simultaneously, the misaligned engagement structure forms a labyrinth seal between housing one and housing two, improving waterproofing and protecting the internal circuitry. This further enhances assembly precision and efficiency, as well as waterproof sealing.
[0013] Preferably, the locking bracket is connected to mounting ears, with a fixing bolt inserted into each mounting ear. A fixing post has a screw hole, and the fixing bolt is threaded into the screw hole. The mounting bracket has a second screw hole, and the PCB board has a through hole. The locking bracket is then connected to a second fixing bolt, which passes through the through hole and is threaded into the screw hole. The mounting ear, through the screw hole of the fixing post, secures the locking bracket to the housing. The second fixing bolt, through the PCB board, is connected to the screw hole, further securing the circuit board to the locking bracket and mounting bracket. This ensures complete fixation of the locking bracket to the housing and achieves high-strength assembly between modules, thereby improving the connection strength between the assembled structures.
[0014] Preferably, the second fixing post has a screw hole three, the support base plate has a screw hole four, and the second housing is fitted with a fixing bolt three, which is threaded into screw holes three and four. The second housing also has a fixing post four, which has a screw hole four. The support base plate has a insertion hole two, which is fitted with a fixing bolt four, which is threaded into screw hole four. The locking bracket is connected to the first housing by fixing bolt one, the mounting bracket is connected to the locking bracket by fixing bolt two, and the first housing and the second housing are connected by fixing bolt three. Before connecting fixing bolt three, the support base plate is fixed by fixing bolt four to facilitate the connection of the second housing. This achieves the effect of allowing the various modules of the assembly to be assembled strongly and sequentially, stably connected, and easy to disassemble and maintain later.
[0015] The beneficial effects of this utility model are: the tactile switch assembly can be modularly assembled, thereby improving assembly efficiency and facilitating subsequent maintenance; waterproof sealing protects the internal circuit; improves assembly stability and prevents open circuit failures; the components are highly precise and have a compact structure; improves the rationality of the assembly's structural layout; enhances connection tightness; and improves the connection strength between the assembly structures.
