[0066] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0067] See Figure 1 The present invention provides a car seat adjustment switch that separates two or more switches that share a switch box in the prior art into independent switch modules. That is, each switch has an independent housing. This allows the car seat adjustment switch to be arranged in a minimal space system, allowing the flexible arrangement of the switch modules based on the customer's design. Each switch module can form a platform switch based on its corresponding adjustment function, and the button design can be used to meet the design requirements of different manufacturers. Furthermore, the platformization of the switch module facilitates the design of other components, such as wiring harnesses and side panels, and allows for the continued use of some tests, which can significantly reduce production costs. The present invention is described below with reference to the accompanying drawings.

[0068] See Figure 1 , shows a front view of the first embodiment of the automobile seat adjustment switch of the utility model. Figure 2 , shows the back view of the first embodiment of the automobile seat adjustment switch of the utility model. Figure 3 , shows a schematic diagram of the three-dimensional structure of the first embodiment of the automobile seat adjustment switch of the utility model in the state where the button is facing downward. Figures 1 to 3 , the utility model of the automobile seat adjustment switch is described.

[0069] like Figures 1 to 3 As shown, the car seat adjustment switch of the present invention includes a switch module, a button 22, a wiring harness assembly 23 and a connector 232, wherein at least two switch modules are provided, and each switch module is independent of each other. Figures 1 to 3 The two switch modules shown in FIG are the backrest switch module 21 and the rail switch module 21′. Figure 4 and Figure 7 As shown, each switch module has a circuit board and a control switch connected to the circuit board. The control switch is used to generate corresponding control signals, such as opening, closing, etc., or to realize corresponding functions of controlling the car seat, such as adjusting the seat back backward or forward, etc. Figures 4 to 8 As shown, the backrest switch module 21 is an independent switch module, including a circuit board 211 and a control switch 212 connected to the circuit board 211. Figures 9 to 13 As shown, the slide rail switch module 21 ′ is also an independent switch module, including a circuit board 211 ′ and a control switch 212 ′ connected to the circuit board 211 ′.

[0070] exist Figure 1 In the first embodiment shown, the car seat adjustment switch includes two switch modules, wherein the backrest switch module 21 is used to control the backrest adjustment function, and the slide rail switch module 21′

[0071] It is used to realize the control of the seat cushion adjustment function. Of course, the switch module of the present invention is not limited to this, and more switch modules can be arranged, such as a leg rest switch module and a headrest switch module. The switch module of the present invention includes any two or more of a slide rail switch module, a backrest switch module, a leg rest switch module and a headrest switch module. The button 22 is detachably connected to the corresponding switch module. The button 22 can trigger the control switch (control switch 212, 212′) on the corresponding switch module. By setting a detachable button 22, the button 22 installed on the switch module can adapt to the styling requirements of different manufacturers. Combined with Figure 9 As shown, the wiring harness connection assembly 23 includes a signal line 231 electrically connected to the circuit boards (circuit boards 211, 211') of each switch module, and a connector 232 electrically connected to any one or more (here, "plurality" includes two) of at least two switch modules. The connector 232 is used to connect to the controller that controls the vehicle seat and transmit the control signal output by the control switch to the controller to implement the corresponding function. In other words, when there are two switch modules, the connector 232 can be electrically connected to one switch module, which is then electrically connected to the other switch module, thereby connecting the connector 232 to the two switch modules in series. Alternatively, the connector 232 can be electrically connected to each of the two switch modules, forming a parallel connection.

[0072] In a specific embodiment of the present invention, Figure 9 、 Figure 12 and Figure 13 As shown, the connector 232 includes a connector pin header 2322 that is soldered to the circuit board of the corresponding switch module. In the first embodiment, the connector pin header 2322 of the connector 232 is soldered to the circuit board 211' of the slide switch module 21'. Of course, the solution of the utility model is not limited to this. The connector pin header 2322 of the connector 232 can also be soldered to the circuit board 211 of the backrest switch module 21.

[0073] Furthermore, the circuit board 211 of the backrest switch module 21 and the circuit board 211′ of the rail switch module 21′ are electrically connected via a signal line 231, and the circuit boards 211 and 211′ are connected in series via the signal line 231. Thus, when the connector 232 is provided at the rail switch module 21′, the control signal of the backrest switch module 21 can be transmitted to the connector 232 via the signal line 231 and the circuit board 211′, and then transmitted to the controller via the connector 232. In a specific embodiment of the present invention, Figure 4 、 Figure 7 and Figure 8 As shown, each switch module includes a housing, the interior of which is formed with a space for accommodating the corresponding circuit board and control switch, and a mounting hole is provided on one side of the housing corresponding to the button 22. Figure 7 and Figure 8 As shown, a housing 2133 is formed inside the shell of the backrest switch module 21, and the housing 2133 is used to accommodate the circuit board 211 and the control switch 212. A mounting hole 2134 is provided on one side of the shell corresponding to the button 22. Figure 12 and Figure 13 As shown, an accommodating space 2133 ′ is formed inside the housing of the slide switch module 21 ′. The accommodating space 2133 ′ is used to accommodate the circuit board 211 ′ and the control switch 212 ′. A mounting hole 2134 ′ is provided on one side of the housing corresponding to the button 22 .

[0074] Combine Figure 7 and Figure 8 As shown, when the button 22 is installed, the button 22 can be connected to the control switch 212 in the accommodating space 2133 through the installation hole 2134. Figure 12 and Figure 13 As shown, the button 22 can be connected to the control switch 212' in the accommodating space 2133' through the mounting hole 2134' or, in combination with Figure 18 As shown, the button 22 is opposite to the control switch 212 in the accommodating space 2133 through the mounting hole 2134 , for example, they are arranged opposite each other up and down. By manipulating the button 22 , the control switch 212 can be triggered to realize the corresponding control signal.

[0075] Further, if Figure 7 and Figure 8 As shown, the housing of the backrest switch module 21 includes a first portion 2131 and a second portion 2132 . The first portion 2131 and the second portion 2132 are arranged opposite to each other and are then fastened together by a connector 24 .

[0076] Specifically, the first part 2131 and the second part 2132 can be arranged relative to each other up and down or left and right, and an accommodating space 2133 is formed inside the first part 2131, and the second part 2132 is equivalent to a cover body; the first part 2131 can also be a cover body, and an accommodating space 2133 is formed on the second part 2132, or partial accommodating spaces are formed on both the first part 2131 and the second part 2132.

[0077] Likewise, if Figure 12 and Figure 13 As shown, the slide rail switch module 21′ also includes a first portion 2131′ and a second portion 2132′, which are arranged opposite each other and are further fastened together by a connector 24. Specifically, the first portion 2131′ and the second portion 2132′ can be arranged opposite each other vertically or horizontally, with an accommodating space 2133′ formed inside the first portion 2131′, and the second portion 2132′ serving as a cover. Alternatively, the first portion 2131′ can serve as the cover, and the accommodating space 2133′ can be formed on the second portion 2132′, or both the first portion 2131′ and the second portion 2132′ can have partial accommodating spaces.

[0078] Furthermore, the shell is a plastic part formed by injection molding. The size of the shell is adapted according to the size of the parts arranged inside it, such as the circuit board and the control switch. That is, the size of the shell is slightly larger than the size of the circuit board and the control switch arranged inside it. The structure of the switch module formed after assembly is compact, and the effect of arrangement in the minimum space is achieved.

[0079] In a specific embodiment of the present invention, a slider is further provided in the housing space of the housing, and the upper portion of the slider passes through the mounting hole and is then engaged with the button 22. Figure 7 and Figure 8 In the embodiment, the slider 214 of the backrest switch module 21 is arranged in the accommodating space 2133, and the upper portion of the slider 214 passes through the mounting hole 2134 and is engaged with the button 22. Figure 12 and Figure 13 In the embodiment, the slider 214 ′ of the slide switch module 21 ′ is disposed in the accommodating space 2133 ′, and the upper portion of the slider 214 ′ passes through the mounting hole 2134 ′ and is engaged with the button 22 .

[0080] In a specific embodiment, Figure 7 、 Figure 8 、 Figure 12 and Figure 13 As shown, the control switches 212, 212' are micro switches, or toggle switches, and have a lever 2121, 2121' that is inserted into the sliders 214, 214', thereby being fixedly connected to the sliders 214, 214'. Furthermore, the sliders 214, 214' are connected to the button 22. Thus, when the button 22 is manipulated, the sliders 214, 214' are moved, which in turn drives the levers 2121, 2121' to switch, thereby switching different circuits within the micro switch, thereby forming different electrical circuits and achieving corresponding adjustment functions for the backrest and seat cushion.

[0081] Furthermore, if Figure 7 、 Figure 8 、 Figure 12 and Figure 13 As shown, the sliders 214, 214' are provided with through holes 2143, 2143' corresponding to the levers 2121, 2121' of the control switches 212, 212', and the levers 2121, 2121' are inserted into the through holes 2143, 2143'. The sliders 214, 214' pass through the mounting holes 2134, 2134' on the housing and are then engaged with the bottom of the button 22.

[0082] Furthermore, if Figure 7 、 Figure 8 、 Figure 12 and Figure 13 As shown, the sliders 214, 214' are provided with first buckles 2141, 2141'; Figure 5 and Figure 10 As shown, the button 22 is provided with a second snap 221 that matches the first snap 2141, 2141'. The second snap 221 can be engaged with the first snap 2141, 2141', thereby achieving a snap connection between the button 22 and the sliders 214, 214. The snap connection between the first snap 2141, 2141' and the second snap 221 achieves a detachable connection between the button 22.

[0083] Preferably, the first buckles 2141 and 2141 ′ are buckling protrusions, and the second buckle 221 is a buckling slot or a buckle port, or the first buckles 2141 and 2141 ′ are buckling slots or a buckle port, and the second buckle 221 is a buckling protrusion.

[0084] Furthermore, the upper portion of the slider 214, 214' is provided with a first rib-groove structure 2142, 2142'; Figure 6 and Figure 11As shown, the lower portion of the button 22 corresponds to the first rib-groove structure 2142, 2142' is provided with a second rib-groove structure 222; the second rib-groove structure 222 can be aligned with the first rib-groove structure

[0085] The first rib-groove structure 2142, 2142' and the second rib-groove structure 222 cooperate to allow the button 22 to be engaged with the sliders 214, 214', so that the button 22 can be moved synchronously with the sliders 214, 214'.

[0086] Furthermore, if Figure 7 、 Figure 8 、 Figure 12 and Figure 13 As shown, baffles 215, 215' are provided on the circuit boards 211, 211', and the baffles 215, 215' are buckled on the corresponding control switches 212, 212'. The baffles 215, 215' are provided to support the sliders 214, 214'. Preferably, the sliders 214, 214' are placed on the corresponding baffles 215, 215'.

[0087] Through holes 2151 , 2151 ′ are formed on the baffles 215 , 215 ′ corresponding to the shifting rods 2121 , 2121 ′. The shifting rods 2121 , 2121 ′ can extend from the through holes 2151 , 2151 ′ and then be inserted into the sliders 214 , 214 ′.

[0088] like Figure 17 and Figure 18 As shown, another embodiment of the switch module is shown. In this embodiment, the control switch 212 on the switch module 21 is a push switch, which is provided with a push contact 2122; the button 22 passes through the mounting hole 2134 and is opposite to the corresponding push contact 2122.

[0089] Preferably, the pressing contact pin 2122 is made of conductive rubber. When the button 22 is pressed downward, the button 22 can contact the pressing contact pin 2122, thereby connecting the corresponding electrical circuit on the circuit board 211 and generating a corresponding control signal.

[0090] Furthermore, a connector 232 is provided on the side of the first portion 2131 of the housing of the switch module 21 . The connector pin seat 2322 of the connector 232 is provided on the circuit board 211 , and the connector housing is provided on one side of the housing of the switch module 21 .

[0091] Furthermore, the button 22 is provided with a first connecting portion 223; the interior of the shell is provided with a matching second connecting portion corresponding to the first connecting portion 223, and the second connecting portion can be slidably connected to the first connecting portion, thereby realizing a sliding connection between the button and the shell.

[0092] Specifically, the first connecting portion 223 can be a slot that is vertically arranged, and the second connecting portion can be a block that slides into the slot, which not only serves as a connection limit between the button 22 and the housing, but also allows the button 22 to be pressed downward. Alternatively, the first connecting portion 223 can be a block, and the second connecting portion can be a vertical slot.

[0093] In a specific embodiment of the present invention, Figure 9 、 Figure 12 and Figure 13 As shown, the connector 232 further includes a connector housing 2321 , which is integrated into the bottom surface or side surface of the housing.

[0094] Specifically, in the first embodiment, the connector 232 is provided on the slide rail switch module 21 ′, and is combined with the Figure 12 and Figure 13 As shown, the connector 232 is arranged on the bottom surface of the slide switch module 21′, that is, the connector 232 is arranged at the bottom of the second part 2132′. The connector 232 can be integrated with the second part 2132′ of the shell of the slide switch module 21′, and can be connected together by injection molding, gluing, bolting, etc.

[0095] like Figures 14 to 16 , another modified example of a slide switch module 21 ′ with a connector 232 is shown. In this embodiment, the connector 232 is arranged on a side of the slide switch module 21 ′, specifically on the side of the housing of the slide switch module.

[0096] In a specific embodiment of the present invention, Figure 2 and Figure 3 As shown, the connector 232 is electrically connected to any one of the at least two switch modules. The wiring harness assembly 23 also includes at least one tensile protection wire 233 connected between the circuit boards of each switch module. The length of each tensile protection wire 233 is shorter than that of the signal wire 231. Specifically, one or more tensile protection wires 233 can be provided between the circuit boards of the two switch modules. Alternatively, one or more tensile protection wires 233 can be provided between the circuit boards of two switch modules in more than two switch modules.

[0097] When the circuit board 211 on the backrest switch module 21 is connected to the circuit board 211′ on the slide rail switch module 21′ through the signal line 231, a tensile protection line 233 is set between the circuit board 211 and the circuit board 211′. The length of the tensile protection line 233 is less than the length of the signal line 231. In this way, when a pulling force is applied to the switch module during the installation of the switch module, the tensile protection line 233 can withstand the pulling force, thereby protecting the signal line 231 from being damaged.

[0098] When selecting the tensile protection line 233 , it is sufficient to select the tensile protection line 233 that can meet the tensile requirements.

[0099] Figure 3 In the illustrated embodiment, the tensile protection wire 233 is wrapped around the signal wire 231 via an insulating sheath. Alternatively, the tensile protection wire 233 can be provided separately, that is, not wrapped around the signal wire 231 via the insulating sheath. The location of the tensile protection wire 233 can be different from that of the signal wire 231. That is, when the signal wire 231 is provided on one side of the switch module, the tensile protection wire 233 can be provided on the other side. The tensile protection wire 233 can form connections at different locations between the two circuit boards to resist pullout forces at different locations.

[0100] like Figure 19 As shown, the first embodiment of the automobile seat adjustment switch of the present invention is installed on the side panel 11 of the automobile seat, wherein the slide switch module 21′ with the connector 232

[0101] The switch modules can be arranged in a matching manner according to the installation space on the side panel 11 . Since the two switch modules are connected via a signal line, flexible arrangement of the switch modules is achieved.

[0102] like Figure 20 As shown, the effect of the car seat adjustment switch of three switch modules being installed on the side panel 11 of the car seat is shown. The backrest switch module 21, the slide rail switch module 21′ and the leg rest switch module 21″ are arranged side by side on the side panel 11, among which the leg rest switch module 21″ is a switch for controlling the leg rest adjustment function.

[0103] The installation position of the car seat adjustment switch of the present invention is not limited to the position of the side panel of the car seat, and it can also be set at other positions of the car seat, such as Figure 32 As shown, the car seat adjustment switch is arranged on the seat back plate 12 of the car seat. Figure 33 As shown, the car seat adjustment switch can also be arranged on the car door 13.

[0104] In a specific embodiment of the utility model, Figures 21 to 23 As shown, in the second embodiment, each switch module is electrically connected to a signal line, and the other end of each signal line is electrically connected to the connector 232 in a parallel manner.

[0105] It is conceivable that one end of the signal line is electrically connected to the circuit board of each switch module, and the other end may also be directly electrically connected to the connector 232 .

[0106] like Figure 22 and Figure 23As shown, the backrest switch module 21 and the slide rail switch module 21′ are each electrically connected to a signal line. The other ends of the two signal lines are electrically connected to the connector 232 through parallel wiring. The connector 232 is a separate component from the backrest switch module 21 and the slide rail switch module 21′. The circuit board 211 of the backrest switch module 21 is electrically connected to the first signal line 235, and the slide rail switch module 21′ is electrically connected to the second signal line 236. The first signal line 235 and the second signal line 236 are electrically connected to the connector 232 after being paralleled.

[0107] like Figures 24 to 26 As shown, a first signal line 235 is led out from the bottom of the second part 2132 of the shell of the backrest switch module 21. One end of the first signal line 235 inside the shell is electrically connected to the circuit on the circuit board 211, and the other end of the first signal line 235 is electrically connected to the connector 232.

[0108] like Figures 27 to 29 As shown, a second signal line 236 is led out from the bottom of the second part 2132' of the housing of the slide rail switch module 21'. One end of the second signal line 236 is electrically connected to the circuit board 211' in the housing, and the other end is electrically connected to the connector 232. Figure 23 As shown, the first signal line 235 and the second signal line 236 are electrically connected to the connector 232 through parallel lines, thereby realizing the electrical connection between the connector 232 and the two switch modules. Figure 31 As shown, when there is insufficient space around the switch module to place the connector, the connector can be placed at another location with sufficient space by adjusting the lengths of the first signal line and the second signal line.

[0109] Further, if Figure 22 and Figure 23 As shown, a lock 234 for fixing the first signal line 235 is provided at the bottom of the backrest switch module 21 .

[0110] like Figure 30 As shown, the car seat adjustment switch is installed on the side panel 11 of the car seat, and the connector 232 is installed in a space far away from the backrest switch module 21 and the slide rail switch module 21' through the setting of the signal line. The connector 232, which is relatively independent of the switch module, has great flexibility in choosing the installation position.

[0111] like Figure 31 As shown, the car seat adjustment switch has three switch modules, namely the backrest switch module 21, the slide rail switch module 21′ and the leg rest switch module 21″, which are respectively connected to the connector 232 through a wiring harness. The connector 232 is installed in a space far away from the three switch modules through the setting of signal lines.

[0112] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
