Description

Technical Field

[0001] This invention relates to the field of vehicle components, and more particularly to a multi-position switch assembly for vehicles, a multi-position switch for vehicles, and a vehicle. Background Technology

[0002] Most existing vehicle window switches are five-position sliding switches. These switches use a metal contact piece mounted on a sliding block that is interference-fitted with the PCBA (Printed Circuit Board Assembly). The metal contact piece slides across the PCBA surface, opening and closing the circuit at different positions to control the position. Lubricating oil needs to be applied between the metal contact piece and the PCBA to reduce friction and noise. Furthermore, because the contact piece only engages to conduct the circuit after sliding to a specific point, the accuracy of the metal contact piece's displacement is crucial. The interval between each position is typically only a few millimeters; even slight deviations in the movement distance can easily lead to poor disengagement or button malfunction. Additionally, the numerous and small push rods that mate with the metal contact piece make installation complex and prone to rework due to omissions. Summary of the Invention

[0003] This invention provides a multi-gear switch assembly for vehicles, a multi-gear switch for vehicles, and a vehicle. The multi-gear switch assembly changes the horizontally moving contact-type shifting to a vertically moving compression-type shifting, solving the defects of existing technologies such as difficulty in controlling the center movement accuracy, numerous parts, and high shifting friction.

[0004] The present invention is implemented as follows: a multi-position switch assembly for automobiles includes a button, a sliding block located below the button and fixedly connected to the button, two elastic reset members located on opposite sides of the sliding block, a plurality of lever arms located at the bottom of the sliding block, conductive rubber located at the bottom of the lever arms, a circuit board located at the bottom of the conductive rubber and in contact with the conductive rubber, and a housing, wherein the button, the sliding block, and the elastic reset members are all located within the housing;

[0005] Using the contact surface between the conductive rubber and the circuit board as a reference surface, the button drives the sliding block to move in two directions relative to the reference surface. The sliding block is provided with several guides that contact the lever arm.

[0006] The elastic reset component is fixed between the sliding block and the outer shell and drives the sliding block to reset.

[0007] The lever arm is provided with a plurality of elastic arms that cooperate with the corresponding guide, and the free end of the elastic arm is provided with a compression column.

[0008] When the sliding block moves, one end of the extrusion column cooperates with the guide to make the extrusion column move perpendicular to the reference plane, and the other end of the extrusion column extrudes the conductive rubber toward the circuit board, so that the extrusion column, the conductive rubber and the circuit board are electrically connected.

[0009] The vehicle multi-position switch assembly has five positions, with four positions provided for the guide and four for the elastic arm. The initial position is set with the initial position of the sliding block. The button drives the sliding block to move in two opposite directions along the reference plane, with two forward and two backward positions, thus achieving five-position control.

[0010] The conductive rubber has rubber protrusions, and the extrusion column extrudes the rubber protrusions.

[0011] The outer shell is provided with a limiting block, and the sliding block is provided with a limiting groove that cooperates with the limiting block.

[0012] The guide is an inclined surface, and one end of the extrusion column is an arc surface. The inclined surface and the arc surface work together to convert the horizontal movement of the sliding block into the vertical movement of the extrusion column.

[0013] The button has openings extending from both sides, and the sliding block has a buckle that engages with the opening; or the sliding block has an opening, and the button has a buckle that engages with the opening.

[0014] The lever arm component is integrally formed with the outer shell as a whole.

[0015] Four lever arms and four guides are arranged in sequence. The extension directions of the two lever arms on both sides and the two guides in the middle are the same, and the extension directions of the two lever arms on both sides and the two guides in the middle are defined as the first direction. The extension directions of the two lever arms in the middle and the two guides on both sides are the same, and the extension directions of the two lever arms in the middle are defined as the second direction. The extension direction of the second direction is opposite to the extension direction of the first direction. When the two guides on both sides contact the lever arms on both sides, the button drives the sliding block to move two stops along the second direction. When the two guides in the middle contact the lever arms in the middle, the button drives the sliding block to move two stops along the first direction.

[0016] A multi-position switch for vehicles includes the aforementioned multi-position switch assembly, wherein two multi-position switch assemblies are provided; the outer casing is provided with two receiving slots and a retaining wall located between the two receiving slots, and the two multi-position switch assemblies are respectively located in the two receiving slots; one end of one elastic reset member abuts against the retaining wall, and the other end of the elastic reset member (3) is fixed on the sliding block (2).

[0017] A vehicle, wherein the vehicle multi-position switch assembly is described.

[0018] This invention relates to a multi-gear switch assembly for vehicles, a multi-gear switch for vehicles, and a vehicle that uses a sliding switch instead of a spring, gear pin, and rail structure for gear shifting. This results in frictionless shifting, low noise, and high reliability. Furthermore, the housing lever structure is integrated into a single part, simplifying assembly, reducing processes, increasing production efficiency, lowering product costs, and making the product more competitive in the market.

Detailed Implementation

[0027] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the description of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0028] Example 1

[0029] like Figure 1 , 2As shown, a multi-position switch assembly for automobiles includes a button 1, a sliding block 2 located below and fixedly connected to the button 1, two elastic reset members 3 located on opposite sides of the sliding block 2, multiple lever members 4 located at the bottom of the sliding block 2, conductive rubber 5 located at the bottom of the lever members 4, a circuit board 6 located at the bottom of the conductive rubber 5 and in contact with the conductive rubber 5, and a housing 7. The button 1, the sliding block 2, and the elastic reset members 3 are all located inside the housing 7.

[0030] With the contact surface between the conductive rubber 5 and the circuit board 6 as the reference surface, the button 1 drives the sliding block 2 to move in two directions relative to the reference surface. The sliding block 2 is provided with a number of guides 21 that contact the lever arm 4.

[0031] The elastic reset member 3 is fixed between the sliding block 2 and the outer casing 7 and drives the sliding block 2 to reset, so that the position of the switch assembly is in the initial position. In this embodiment, preferably, the elastic reset member 3 is a position rubber to simplify the required parts.

[0032] Furthermore, in order to further simplify the structure and reduce the overall number of parts for easier assembly, the lever arm 4 and the outer shell 7 are integrally formed as a whole.

[0033] like Figure 3 , 4 As shown, the lever arm 4 is provided with a plurality of elastic arms 41 that cooperate with the corresponding guide 21. The free end of the elastic arm 41 is provided with a pressing column 42. When the sliding block 2 moves, one end of the pressing column 42 cooperates with the guide 21 to make the pressing column 42 move perpendicular to the reference plane, and the other end of the pressing column 42 presses the conductive rubber 5 toward the circuit board 6, so that the pressing column 42, the conductive rubber 5 and the circuit board 6 are electrically connected.

[0034] The vehicle multi-gear switch assembly has five gears, with four each for the guide member 21 and the elastic arm 41. Taking the initial position of the sliding block 2 as the initial gear I, the button 1 drives the sliding block 2 to move in two opposite directions along the reference plane, with two gears each for forward and backward movement, thus achieving five-gear control.

[0035] Taking this embodiment as an example, when button 1 is pushed forward to the first position, the first pressing column is pressed down, causing the corresponding circuit board's gear position circuit to conduct, while the other pressing columns are in the initial rotation state, which is the forward gear one position; when button 1 is pushed forward to the second position, the first and second pressing columns are pressed down, causing the corresponding circuit board's gear position circuit to conduct, while the other pressing columns are in the initial rotation state, which is the forward gear two positions; after being released, button 1 automatically returns to the initial gear position under the action of the elastic reset member 3; when button 1 is pushed backward, the same method is used to move backward one or two positions, realizing the switching control of five gears.

[0036] Furthermore, in order to improve the conductivity reliability of the extrusion and ensure the effect of the extruded conductive rubber 5, the conductive rubber 5 is provided with rubber protrusions 51, and the extrusion column 42 extrudes the rubber protrusions 51.

[0037] Furthermore, in order to control the extreme position of the button 1 and facilitate operation, a limit block 71 is provided on the outer shell 7, and a limit groove 22 that cooperates with the limit block 71 is provided on the sliding block 2.

[0038] like Figure 5 As shown, considering the convenience of arrangement, in this embodiment, the guide 21 is an inclined surface, and one end of the extrusion column 42 is an arc surface. The inclined surface and the arc surface cooperate to transform the horizontal movement of the sliding block 2 into the vertical movement of the extrusion column 42. When the extrusion column 42 moves, it squeezes the conductive rubber 5 through the rubber protrusion 51, so that the control circuit corresponding to the circuit board 6 is turned on, thereby realizing the control of the gear position.

[0039] like Figure 6 As shown, the button 1 has openings 11 extending from both sides, and the sliding block 2 has a buckle 23 that engages with the opening 11; or the sliding block has an opening, and the button 1 has a buckle that engages with the opening.

[0040] Four lever arms 4 and four guides 21 are arranged in sequence. The extension directions of the two lever arms 4 located on both sides and the two guides 21 located in the middle are the same. The extension directions of the two lever arms 4 located on both sides and the two guides 21 located in the middle are defined as the first direction. The extension directions of the two lever arms 4 located in the middle and the two guides 21 located on both sides are the same. The extension directions of the two lever arms 4 located in the middle are defined as the second direction. The extension direction of the second direction is opposite to the extension direction of the first direction. When the two guides 21 located on both sides contact the lever arms 4 located on both sides, the button 1 drives the sliding block 2 to move two stops along the second direction. When the two guides 21 located in the middle contact the lever arms 4 located in the middle, the button 1 drives the sliding block 2 to move two stops along the first direction.

[0041] like Figure 7 As shown, the outer casing 7 has two slots 72 located at its bottom. Two adjacent lever arms 4 (one extending in a first direction and the other in a second direction) are located in one slot 72; the other two lever arms 4 (one extending in the first direction and the other in the second direction) are located in the other slot 72. Figure 7As shown, a multi-position switch for vehicles includes the aforementioned multi-position switch assembly, of which two are provided; the outer casing 7 is provided with two receiving slots 73 and a retaining wall 8 located between the two receiving slots 73, and the two multi-position switch assemblies are respectively located in the two receiving slots 73; one end of one of the elastic reset members 3 abuts against the retaining wall 8, and the elastic reset member 3 is fixed between the sliding block 2 and the retaining wall 8.

[0042] In another embodiment of the present invention, a vehicle is provided, including the above-described automotive multi-position switch assembly.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
