Description

Technical Field

[0001] The utility model relates to the technical field of automobile switches, in particular to a steering wheel switch assembly with butterfly-type vibration feedback. Background Art

[0002] With the rapid development of current automotive electronic technology, many automotive steering wheel switches have realized the vibration function, but most steering wheel switches use plastic bracket exciters, and there are fewer butterfly-type vibration steering wheel switches that use metal bracket exciters.

[0003] The existing utility model patent number is 202023003075.5, which is a semi-suspended structure of a steering wheel switch with vibration feedback, including a steering wheel body, a cover plate is provided on the working surface of the steering wheel body, the cover plate includes side wings, a damping module is provided at one end of the side wing mounting surface, a fixing module is provided at the other end of the side wing mounting surface, and a vibration module is provided on the side wing mounting surface between the damping module and the fixing module, so that the side wing, the damping module, the fixing module and the vibration module form a feedback module of a cantilever beam structure, which not only simplifies the vibration touch suspension structure, but also gives the driver a strong vibration feedback experience and operation feel, and takes into account the manufacturing and maintenance costs.

[0004] However, the structure produces a lot of noise when vibrating, and the vibration feedback and operating feel are not particularly good. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a steering wheel switch assembly that realizes unique shrapnel vibration feedback through a metal exciter to achieve a good vibration feel, and further realizes butterfly-like vibration on both sides with low noise.

[0006] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: a steering wheel switch assembly with butterfly-type vibration feedback, comprising a base and a panel, circuit boards are provided at both ends of the base, a pressing groove is provided on the panel, a shell covering the circuit boards on both sides respectively is provided between the base and the panel, a vibration control component for vibrating the shells at both ends respectively is provided on the side of the panel facing the shell, the vibration control component comprises a bracket fixed to the panel at both ends, a mounting groove is provided on the side of the bracket facing the shell, a metal exciter is fitted in the mounting groove, a decorative panel is provided on the side wall below the mounting groove and abuts against the panel on the side of the bracket facing the panel, and a suspension support structure is also provided in the shell for driving the shell and the panel to vibrate in butterfly manner when the metal exciter vibrates.

[0007] By adopting the above technical scheme, since the shell and the panel are assembled together by a suspended support structure, and the base and the panel are fixed in the middle by bolts, an installation method with both ends suspended and the middle fixed is formed. In addition, this installation method allows the decorative panels at both ends to produce slight deformation after being pressed, thereby triggering the metal exciter. The metal exciter is attached to the bracket and fixed to the panel by bolts. Therefore, when the metal exciter vibrates through the corresponding driving waveform, it will only vibrate the shells on both sides, thereby driving the two sides of the panel to vibrate, thereby forming a vibration at both ends similar to the shape of a butterfly flapping its wings. At the same time, no loud noise will be generated during vibration, and the sound is small. At the same time, it can also form a unique vibration feedback of shrapnel vibration, thereby realizing butterfly-like vibration on both sides.

[0008] A steering wheel switch assembly with butterfly-type vibration feedback can be further configured as follows: the suspension support structure includes a hollow rubber pad arranged in an outer shell, a screw plug is passed through the rubber pad on one side facing the panel, a semi-arc-shaped slot for the screw plug to be inserted and fixed on the side facing the screw plug is provided on the panel, a screw hole is provided on the side facing the screw plug towards the base, and a screw is passed through the screw hole.

[0009] By adopting the above technical solution, screws are used to limit rubber pads and screw plugs, and the nut end of the screw plug is extended into the semi-arc-shaped slot to complete the suspension support. If it is directly fastened by bolts, butterfly vibration cannot be achieved, but the entire switch assembly vibrates, the vibration frequency is high, and the noise is also high. At the same time, the rubber pad can also play a role in reducing noise during vibration.

[0010] A steering wheel switch assembly with butterfly-type vibration feedback can be further configured as follows: the screw plug block is provided with a U-shaped clamping block protruding toward one side of the panel, and the semi-arc-shaped clamping groove is provided with a clamping rib that cooperates with the notch in the middle of the U-shaped clamping block.

[0011] By adopting the above technical solution, the U-shaped block and the clamping rib cooperate with each other to complete the fixation. Compared with bolt fixation, this has a certain suspension height, and also has a certain stability while providing suspension support, so that the two ends of the panel and the shell can achieve butterfly vibration.

[0012] A steering wheel switch assembly with butterfly-type vibration feedback can be further configured as follows: a plurality of function keys are arranged on the panel, and a sensor connected to a circuit board circuit is arranged at a position corresponding to the function keys on a side of the panel facing the housing.

[0013] By adopting the above technical solution, the function buttons can be push-type function buttons or touch-type function buttons. By pressing or touching, the sensor in the panel can be triggered and a signal can be sent to the circuit board, thereby realizing multiple functions, such as wipers, lights, turn signals, cruise control and other functions.

[0014] A steering wheel switch assembly with butterfly-type vibration feedback can be further configured as follows: the outer peripheral surface of the decorative panel is protruded with a plurality of embedded blocks that abut against the side of the panel facing the base, and the side of the decorative panel facing the bracket is protruded with a plurality of support columns that abut against the bracket.

[0015] By adopting the above technical solution, the embedded block can prevent the decorative panel from slipping out of the mounting groove and keep it always below the mounting groove. At the same time, the support column can also slightly change the distance between the coil part on the bracket and the magnetic core part on the metal exciter when the decorative panel is pressed and deformed to generate a signal, thereby prompting the metal exciter to work and generate vibration. At the same time, the support column can also make the decorative panel more stably installed above the bracket.

[0016] A steering wheel switch assembly with butterfly-type vibration feedback can be further configured as follows: a waterproof rubber covering the outside of a circuit board is fixedly arranged between the base and the shell.

[0017] By adopting the above technical solution, the waterproof rubber can effectively prevent water from entering the circuit board. Nowadays, many people directly touch the steering wheel switch with sweaty hands. If the waterproof rubber is not provided, it will not only cause a short circuit in the circuit board, but may even cause a dangerous situation of electric shock to the human body. The provision of the waterproof rubber not only increases the service life of the circuit board, but also increases the safety of the product.
