Description

Technical Field

[0001] This invention belongs to the field of touch switch manufacturing technology, specifically a touch vibration switch. Background Technology

[0002] In automobiles, touchscreens are gradually replacing mechanical switches. However, existing touchscreen switches provide feedback to the driver through lights after being touched, requiring the driver to turn or look down to check if the touch is effective (i.e., to confirm whether the touch switch mode has been switched). This distracts the driver and causes a shift in their gaze, posing a safety hazard. Therefore, it is necessary to design a switch that provides non-visual feedback to the driver after touching the touch switch. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by designing a touch vibration switch by setting several push switches on the lower surface of the touch switch in conjunction with a linear motor. This allows the touch switch to provide vibration feedback to the driver after the driver applies a certain amount of force to touch the switch, thus eliminating the need for the driver to look at the touch screen. This solves the safety hazard problem caused by the current touch switches using light emission.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A touch vibration switch includes a housing, within which a circuit board and a linear motor are disposed. The circuit board and the linear motor are electrically connected via a plurality of parallel push switches. The force-receiving parts of the plurality of push switches are connected to a panel. A functional touch switch is provided on the panel corresponding to each push switch. The housing is supported by a bracket via vibration bolts. The panel is disposed on the upper surface of the bracket, and the linear motor is disposed on the lower surface of the bracket. The outer side wall of the bracket is slidably connected to the inner side wall of the housing.

[0009] Preferably, the elastic rubber is provided with a threaded through hole in the axial direction, and the first bolt and the second bolt are respectively connected to the upper end and the lower end of the elastic rubber through the threaded through hole.

[0010] Preferably, the circuit board has a clearance hole at the location corresponding to the vibration bolt.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention employs a method of setting several push switches on the lower surface of the touch switch in conjunction with a linear motor to design a touch vibration switch. After the driver applies a certain force to touch the touch switch, the touch switch can provide feedback to the driver with vibration information, thus eliminating the need for the driver to move their eyes to the touch screen. This solves the safety hazard problem caused by the current touch switches using light emission.

[0015] 2. In this invention, rubber is selected as the elastic element, which makes the manufacturing cost of the elastic element low, its corrosion resistance good, and its service life long.

[0016] 3. The vibration bolts provided in this invention enable the bracket to generate a slight relative movement (vibration) with respect to the housing under the vibration of the linear motor. The power input terminal and through hole are provided to facilitate the connection of this invention to a power source.

[0017] 4. The present invention uses threaded through holes to connect the elastic rubber to both the first bolt and the second bolt, which is convenient to manufacture, efficient to assemble, and easy to replace after the elastic rubber is damaged.

[0018] 5. The present invention has a latching protrusion on the side wall of the bracket, the upper surface of the latching protrusion is inclined, and a buckle that cooperates with the latching protrusion is vertically downward on the lower surface of the panel.

Detailed Implementation

[0026] See Figure 1-6 A touch vibration switch includes a housing 1, inside which a circuit board 2 and a linear motor 3 are disposed. The circuit board 2 and the linear motor 3 are electrically connected through a plurality of parallel push switches 4. The force-receiving parts of the plurality of push switches 4 are connected to a panel 5. A functional touch switch 6 is provided on the panel 5 corresponding to each push switch 4. The housing 1 is provided with a bracket 7 by vibration bolts. The panel 5 is disposed on the upper surface of the bracket 7, and the linear motor 3 is disposed on the lower surface of the bracket 7. The outer side wall of the bracket 7 is slidably connected to the inner side wall of the housing 1.

[0027] In this embodiment, when the driver (operator) applies a certain force to press the touch switch 6, the press switch 4 receives the force, thereby connecting the linear motor 3 to the circuit board 2. The linear motor 3 then vibrates, indicating that the touch is valid. If the driver (operator) applies a certain force to press the touch switch 6 but the linear motor 3 does not connect to the circuit board 2 and the linear motor 3 does not vibrate, it indicates that the press is invalid. In this case, the driver needs to continue applying force to touch the switch. During this process, the driver does not need to look at the panel 5; he can feel the vibration with his hand. Therefore, this design eliminates the safety hazards of existing touch switches.

[0028] As a preferred embodiment, a partition 8 is provided laterally inside the housing 1. The lower end of the vibration bolt is fixedly connected to the partition 8, and the upper end of the vibration bolt is fixedly connected to the bracket 7. The circuit board 2 is located on the lower surface of the partition 8, and the circuit board 2 is provided with a power input terminal 9. A through hole 10 is provided on the side wall of the housing 1 at the location corresponding to the power input terminal 9. Through the vibration bolt, the bracket 7 can generate a small relative movement (vibration) relative to the housing 1 under the vibration of the linear motor 3. The power input terminal 9 and the through hole 10 are provided to facilitate the connection of the present invention to a power source.

[0029] As a preferred embodiment, the vibration bolt has a specific structure of a first bolt 11 and a second bolt 12. The lower end of the first bolt 11 is fixedly connected to the upper end of the second bolt 12 through an elastic element. The first bolt 11 is fixedly connected to the bracket 7, and the second bolt 12 is fixedly connected to the partition 8. In this embodiment, the fixed connection between the first bolt 11 and the elastic element can be by adhesive bonding, bolt connection, etc.

[0030] As a preferred embodiment, the elastic element is elastic rubber 13. Rubber is chosen primarily because it is low in cost, has good corrosion resistance, and a long service life.

[0031] As a preferred embodiment, the elastic rubber 13 is provided with a threaded through hole 14 in the axial direction. The first bolt 11 and the second bolt 12 are respectively connected to the upper end and the lower end of the elastic rubber 13 through the threaded through hole 14. By using the threaded through hole 14 to connect the elastic rubber 13 to the first bolt 11 and the second bolt 12, it is convenient to manufacture, efficient to assemble, and easy to replace after the elastic rubber 13 is damaged.

[0032] As a preferred embodiment, the circuit board 2 has a clearance hole 15 at the location corresponding to the vibration bolt, thereby reducing the space occupancy rate of the present invention.

[0033] As a preferred embodiment, a limiting rib 16 is provided on the side wall of the bracket 7 above the side wall of the housing 1. By setting the limiting rib 16, the bracket 7 and the housing 1 are prevented from vibrating beyond the necessary limit under the action of the linear motor 3, thus avoiding the situation where the bracket 7 and the housing 1 separate.

[0034] As a preferred embodiment, the side wall of the bracket 7 is provided with a latching protrusion 17, the upper surface of the latching protrusion 17 is inclined, and the lower surface of the panel 5 is provided with a buckle 18 that cooperates with the latching protrusion 17. The buckle 18 is made of elastic plastic. The arrangement of the latching protrusion 17 and the buckle 18 facilitates fixing the bracket 7 and the panel 15 together.

[0035] Preferably, a back cover 19 is provided on the side of the housing 1 facing away from the panel 5, which makes the invention both aesthetically pleasing and effectively protects the power input terminal 9.
