Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, specifically to a seat heating switch and a vehicle. Background Technology

[0002] To enhance the user experience, modern vehicles are equipped with seat heating systems, which users can control using seat heating switches located within the vehicle. Typically, these switches include a left-side seat heating button and a right-side seat heating button. Pressing the left-side button heats the left-side seat, and pressing the right-side button heats the right-side seat.

[0003] Typically, vehicle mounting hardware for installing various function switches has two identical mounting holes spaced close together, used to install the left-side seat heating button and the right-side seat heating button, respectively.

[0004] However, since the two mounting holes are the same shape, and the left and right seat heating buttons are also the same shape, they are easy to confuse and make mistakes during installation. Summary of the Invention

[0005] This disclosure provides a seat heating switch and a vehicle, which can avoid the problem of incorrect installation. The technical solution is as follows:

[0006] On one hand, this disclosure provides a seat heating switch, which includes a base, a switch housing, a left heating button assembly, a right heating button assembly, and a circuit board;

[0007] The switch housing is connected to the base. The switch housing has a left mounting hole and a right mounting hole. The shape of the left mounting hole on a cross section perpendicular to the extension direction of the left mounting hole is asymmetrical. The shape of the right mounting hole on a cross section perpendicular to the extension direction of the right mounting hole is asymmetrical. The extension direction of the left mounting hole is the same as that of the right mounting hole. The left mounting hole and the right mounting hole are symmetrically arranged based on the central plane of the switch housing.

[0008] The left heating button assembly is inserted into the left mounting hole and is slidably connected to the inner wall of the switch housing. The shape of the left heating button assembly on the cross section perpendicular to the extension direction of the left mounting hole is adapted to the shape of the corresponding position of the left mounting hole.

The shape of the right heating button assembly on the cross section perpendicular to the extension direction of the right mounting hole is adapted to the shape of the corresponding position of the right mounting hole.

[0010] The circuit board is located between the left heating button assembly and the base, and between the right heating button assembly and the base. The circuit board is connected to the base and electrically connected to the left heating button assembly and the right heating button assembly.

[0011] In one possible implementation, the left mounting hole has a plurality of first inner sidewalls connected in sequence, and one of the plurality of first inner sidewalls has a first groove.

[0013] The outer wall of the left heating button assembly has a first protrusion, which is located in the first groove;

[0014] The outer wall of the right-side heating button assembly has a second protrusion, which is located in the second groove.

[0015] In one possible implementation, the left heating button assembly includes a left button inner shell and a left button faceplate. The left button inner shell is located in the left mounting hole and is slidably connected to the inner wall of the left mounting hole. The shape of the left button inner shell in a cross section perpendicular to the extending direction of the left mounting hole is adapted to the shape of the corresponding position of the left mounting hole. The left button faceplate is located on the side of the left button inner shell away from the base and is connected to the left button inner shell.

[0016] The right-side heating button assembly includes a right-side button inner shell and a right-side button faceplate. The right-side button inner shell is located in the right-side mounting hole and is slidably connected to the inner wall of the right-side mounting hole. The shape of the right-side button inner shell in a cross section perpendicular to the extension direction of the right-side mounting hole is adapted to the shape of the corresponding position of the right-side mounting hole. The right-side button faceplate is located on the side of the right-side button inner shell away from the base and is connected to the right-side button inner shell.

[0017] In one possible implementation, the switch housing also has a faceplate decorative hole located on the side of the left mounting hole and the right mounting hole away from the base, and communicating with the left mounting hole and the right mounting hole;

[0018] Both the left and right button covers are located in the decorative holes of the covers.

[0019] In one possible implementation, the switch housing also has a decorative strip mounting hole located between the left mounting hole and the right mounting hole, and communicating with the faceplate decorative hole;

[0020] The seat heating switch also includes a decorative strip, the portion of which near the base is located in the decorative strip mounting hole and connected to the inner wall of the decorative strip mounting hole, and the portion of which away from the base is located in the cover decorative hole and between the left button cover and the right button cover.

[0021] In one possible implementation, the left heating button assembly further includes a left micro switch, which is located between the left button inner shell and the circuit board and is electrically connected to the circuit board.

[0022] The right-side heating button assembly also includes a right-side micro switch, which is located between the right-side button inner shell and the circuit board and is electrically connected to the circuit board.

[0023] In one possible implementation, the left heating button assembly further includes a left light assembly and a left light guide. The left light assembly is electrically connected to the circuit board, and the left light guide is located in and connected to the inner shell of the left button. The position of the left light guide corresponds to the position of the left light assembly.

[0024] The left button cover has a first light-transmitting part, and the position of the first light-transmitting part corresponds to the position of the left light guide.

[0025] The right heating button assembly also includes a right light assembly and a right light guide. The right light assembly is electrically connected to the circuit board, and the right light guide is located in the inner shell of the right button and connected to the inner shell of the right button. The position of the right light guide corresponds to the position of the right light assembly.

[0026] The right button cover has a second light-transmitting part, the position of which corresponds to the position of the right light guide.

[0027] In one possible implementation, the outer wall of the switch housing has a snap-fit ​​for engaging with a snap-fit ​​hole on a vehicle mounting component.

[0028] In one possible implementation, the switch housing further includes two first positioning ribs and two second positioning ribs. The two first positioning ribs are respectively located on two opposite first outer walls of the switch housing and are symmetrically arranged based on the central plane of the switch housing. The two second positioning ribs are respectively located on the two opposite first outer walls and are symmetrically arranged based on the central plane of the switch housing. The length of the second positioning ribs in the direction perpendicular to the first outer wall is different from the length of the first positioning ribs in the direction perpendicular to the first outer wall. The first positioning ribs are used to engage with a first positioning groove on the vehicle mounting component, and the second positioning ribs are used to engage with a second positioning groove on the vehicle mounting component.

[0029] On the other hand, embodiments of this disclosure provide a vehicle including a mounting bracket and a seat heating switch as described in any of the preceding claims;

[0030] The seat heating switch is connected to the mounting component.

[0031] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0032] This disclosure provides a seat heating switch. Since the left mounting hole has an asymmetrical shape in a cross-section perpendicular to its extension direction, and the right mounting hole has an asymmetrical shape in a cross-section perpendicular to its extension direction, and the left and right mounting holes are symmetrically arranged based on the central plane of the switch housing, the left heating button assembly cannot be installed in the right mounting hole, and the right heating button assembly cannot be installed in the left mounting hole. This avoids the problem of incorrect installation of the left and right heating button assemblies, thereby improving installation efficiency and convenience.

[0033] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

The terms “upper,” “lower,” “left,” “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0063] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0064] This disclosure provides a seat heating switch, see [link to relevant documentation] Figure 1 and Figure 2 The seat heating switch includes a base 1, a switch housing 2, a left heating button assembly 3, a right heating button assembly 4, and a circuit board 5.

[0065] See Figure 1The base 1 may include a base plate and a first annular side plate, one end of which is connected to the surface of the base plate.

[0066] The switch housing 2 is connected to the base 1, and the connection method can be any reasonable structure.

[0067] In one possible implementation, see Figure 1 and Figure 3 The outer wall of the base 1 has multiple second buckles 11, and the outer wall of the switch housing 2 has multiple second snap-fit ​​holes 28. The end of the switch housing 2 near the base 1 is looped around the outer side of the end of the base 1 near the switch housing 2. Each second buckle 11 is snapped into a different second snap-fit ​​hole 28, thereby realizing the connection between the switch housing 1 and the base 1.

[0068] In one possible implementation, see Figure 3 and Figure 4 (Understandable, Figure 3 This can be a front view of base 1. Figure 4 (This can be a left view of the base 1). The outer wall of the base 1 near the end of the switch housing 2 also has multiple guide ribs 12, and the outer wall of the switch housing 2 near the end of the base 1 has multiple guide grooves 29, with each guide rib 12 located in a different guide groove 29.

[0069] In this way, the fit between the guide rib 12 and the guide groove 29 during installation can improve the ease of installation between the base 1 and the switch housing 2.

[0070] The multiple guide ribs 12 can be located on different outer side walls of the base 1. For example, when the base 1 has a rectangular structure, the multiple guide ribs 12 can be located on two opposite outer side walls of the base 1, and the number of guide ribs 12 distributed on the two opposite outer side walls is different. Correspondingly, the switch housing 2 can have a rectangular structure, and the multiple guide grooves 29 can be located on two opposite outer side walls of the switch housing 2, and the number of guide grooves 29 distributed on the two opposite outer side walls is different. In this way, when installing the base 1 and the switch housing 2, the different numbers of guide ribs 12 and guide grooves 29 on the two outer side walls can avoid the possibility of reverse installation, thereby avoiding incorrect installation.

[0071] See Figure 5The switch housing 2 has a left mounting hole 21 and a right mounting hole 22. The shape of the left mounting hole 21 in a cross-section perpendicular to its extension direction is asymmetrical, meaning there is no surface that makes the shape of the left mounting hole 21 symmetrical in a cross-section perpendicular to its extension direction. The shape of the right mounting hole 23 in a cross-section perpendicular to the extension direction of the right mounting hole 22 is also asymmetrical, meaning there is no surface that makes the shape of the right mounting hole 22 symmetrical in a cross-section perpendicular to its extension direction.

[0072] The extension direction of the left mounting hole 21 can be the same as the extension direction of the right mounting hole 22, or in other words, they can be parallel. The cross section perpendicular to the extension direction of the left mounting hole 21 and the cross section perpendicular to the extension direction of the right mounting hole 22 are parallel.

[0073] The left mounting hole 21 and the right mounting hole 22 are symmetrically arranged based on the central plane m of the switch housing 2. The switch housing 2 may include a second annular side plate, which may have a symmetrical structure in a cross section perpendicular to its extension direction, and may have multiple symmetrical planes, of which the central plane m may be one.

[0074] Thus, since the left mounting hole 21 and the right mounting hole 22 are not symmetrical in cross-section, and the left mounting hole 21 and the right mounting hole 22 are symmetrically arranged based on the central plane m, no matter how the left mounting hole 21 rotates around a straight line perpendicular to the cross-section at any angle, it cannot have the same shape as the right mounting hole 22; similarly, no matter how the right mounting hole 22 rotates around a straight line perpendicular to the cross-section at any angle, it cannot have the same shape as the left mounting hole 21.

[0075] See Figure 1 and Figure 2 The left heating button assembly 3 is inserted into the left mounting hole 21 and is slidably connected to the inner wall of the switch housing 2. The shape of the left heating button assembly 3 on the cross section perpendicular to the extension direction of the left mounting hole 21 is adapted to the shape of the corresponding position of the left mounting hole 21.

[0076] That is, the shape of the left heating button assembly 3 on the cross section perpendicular to the extension direction of the left mounting hole 21 is asymmetrical.

[0077] See Figure 1 and Figure 2 The right heating button assembly 4 is inserted into the right mounting hole 22 and is slidably connected to the inner wall of the switch housing 2. The shape of the right heating button assembly 4 on the cross section perpendicular to the extension direction of the right mounting hole 22 is adapted to the shape of the corresponding position of the right mounting hole 22.

[0078] That is, the shape of the right heating button assembly 3 on the cross section perpendicular to the extension direction of the right mounting hole 22 is asymmetrical.

[0079] Furthermore, the left heating button assembly 3 and the right heating button assembly 4 can be symmetrically arranged based on the central plane m of the switch housing 2. In this way, the left heating button assembly 3 cannot be installed into the right mounting hole 22, and the right heating button assembly 4 cannot be installed into the left mounting hole 21, thus avoiding the risk of incorrect installation.

[0080] See Figure 1 The circuit board 5 is located between the left heating button assembly 3 and the base 1, and between the right heating button assembly 4 and the base 1. The circuit board 5 is connected to the base 1 and electrically connected to the left heating button assembly 3 and the right heating button assembly 4.

[0081] The driver can press the left heating button assembly 3, causing the left heating button assembly 3 to slide relative to the switch housing 2. After sliding to the first target position, it sends a left trigger signal to the circuit board 5. After receiving the left trigger signal, the circuit board 5 sends it to the vehicle controller, which controls the left seat of the vehicle to perform the corresponding heating operation.

[0082] Alternatively, the driver can press the right-side heating button assembly 4, causing it to slide relative to the switch housing 2. After sliding to the second target position, it sends a right-side trigger signal to the circuit board 5. Upon receiving the right-side trigger signal, the circuit board 5 sends it to the vehicle's controller, which then controls the right-side seat of the vehicle to perform the corresponding heating operation.

[0083] In this embodiment of the disclosure, the shape of the left mounting hole 21 and the shape of the right mounting hole 22 can be any shape that meets the above requirements.

[0084] In one possible implementation, see Figure 5 The left mounting hole 21 has a plurality of first inner sidewalls connected in sequence, and one of the first inner sidewalls has a first groove 211. The right mounting hole 22 has a plurality of second inner sidewalls connected in sequence, and one of the second inner sidewalls has a second groove 221. The outer sidewall of the left heating button assembly 3 has a first protrusion 31 located in the first groove 211. The outer sidewall of the right heating button assembly 4 has a second protrusion 41 located in the second groove 221.

[0085] The first groove 211 and the recess 221 can be symmetrically arranged based on the central plane m of the switch housing 2. Correspondingly, the first protrusion 31 and the second protrusion 41 can be symmetrically arranged based on the central plane m of the switch housing 2.

[0086] The above structure achieves that the left mounting hole 21 is itself an asymmetrical structure, and the right mounting hole 22 is itself an asymmetrical structure, but the two are symmetrically set based on the central plane m.

[0087] The above structure is only one possible structure of the left mounting hole 21 and the right mounting hole 22. It can also be any other structure. For example, two protrusions can be provided on one of the first inner sidewalls of the left mounting hole 21, two protrusions can be provided on one of the second inner sidewalls of the right mounting hole 22, two grooves can be provided on the outer sidewall of the left heating button assembly 3, two grooves can be provided on the outer sidewall of the right heating button assembly 4, and so on.

[0088] In one possible implementation, the structure of the left-side heating button assembly 3 can be: see [link to relevant documentation] Figure 1 The left heating button assembly 3 includes a left button inner shell 32 and a left button faceplate 33. The left button inner shell 32 is located in the left mounting hole 21 and is slidably connected to the inner wall of the left mounting hole 21. The shape of the left button inner shell 32 on the cross section perpendicular to the extension direction of the left mounting hole 21 is adapted to the shape of the corresponding position of the left mounting hole 21. The left button faceplate 33 is located on the side of the left button inner shell 32 away from the base 1 and is connected to the left button inner shell 32.

[0089] The left button cover 33 can be located outside the left mounting hole 21, making it easier for the driver to press it.

[0090] When the driver operates the device, he can press the left button cover 33. The left button cover 33 causes the left button inner shell 32 to slide along the extension direction of the left mounting hole 21. After sliding to the first target position, it will send a left trigger signal to the circuit board 5. After receiving the left trigger signal, the circuit board 5 sends it to the vehicle controller, which controls the left seat of the vehicle to perform the corresponding heating operation.

[0091] In one possible implementation, the connection structure between the left button inner shell 32 and the left button faceplate 33 can be: see [link / reference] Figure 6 and 7 The left button inner shell 32 has multiple first slots 321 on the end face near the left button cover 33, and the left button cover 33 has multiple first blocks 332 on the surface facing the left button inner shell 32. Each first block 332 engages with a different first slot 321, thereby realizing the connection between the left button inner shell 32 and the left button cover 33.

[0092] Understandable, Figure 6 This is a front view of the end of the left button inner shell 32 near the left button faceplate 33. Figure 7This is a front view of the end of the left button cover 33 near the left button inner shell 32.

[0093] In one possible implementation, the sliding connection between the inner shell 32 of the left button and the inner wall of the left mounting hole 21 can be: see... Figure 5 and Figure 6 The outer wall of the left button inner shell 32 has multiple first sliders 322, and the inner wall of the left mounting hole 21 has multiple first grooves 212. Each first slider 322 is located in a different first groove 212 and is slidably connected to the corresponding first groove 212, thereby realizing the slidable connection between the left button inner shell 32 and the inner wall of the left mounting hole 21.

[0094] Correspondingly, the structure of the right-side heating button assembly 4 can be as follows: (See...) Figure 1 The right heating button assembly 4 includes a right button inner shell 42 and a right button faceplate 43. The right button inner shell 42 is located in the right mounting hole 22 and is slidably connected to the inner wall of the right mounting hole 22. The shape of the right button inner shell 42 on the cross section perpendicular to the extension direction of the right mounting hole 22 is adapted to the shape of the corresponding position of the right mounting hole 22. The right button faceplate 43 is located on the side of the right button inner shell 42 away from the base 1 and is connected to the right button inner shell 42.

[0095] The right button cover 43 can be located outside the right mounting hole 22, making it easier for the driver to press it.

[0096] When the driver operates the device, he can press the right button cover 43. The right button cover 43 causes the right button inner shell 42 to slide along the extension direction of the right mounting hole 22. After sliding to the second target position, it will send a right trigger signal to the circuit board 5. After receiving the right trigger signal, the circuit board 5 sends it to the vehicle controller, which controls the right seat of the vehicle to perform the corresponding heating operation.

[0097] In one possible implementation, the connection structure between the right button inner shell 42 and the right button faceplate 43 can be: see [link / reference] Figure 8 and Figure 9 The right button inner shell 42 has multiple second slots 421 on the end face near the right button cover 43, and the right button cover 43 has multiple second blocks 432 on the surface facing the right button inner shell 42. Each second block 432 engages with a different second slot 421, thereby realizing the connection between the right button inner shell 42 and the right button cover 43.

[0098] Understandable, Figure 8 This is a front view of the end of the right button inner shell 42 near the right button faceplate 43. Figure 9This is a front view of the end of the right button cover 43 near the right button inner shell 42.

[0099] In one possible implementation, the sliding connection between the inner shell 42 of the right button and the inner wall of the right mounting hole 22 can be: see... Figure 5 and Figure 8 The outer wall of the inner shell 42 of the right button has multiple second sliders 422, and the inner wall of the right mounting hole 22 has multiple second slide grooves 222. The second sliders 422 are located in different second slide grooves 222 and are slidably connected with the corresponding second slide grooves 222, thereby realizing the sliding connection between the inner shell 42 of the right button and the inner wall of the right mounting hole 22.

[0100] In one possible implementation, see Figure 5 The switch housing 2 may also have a faceplate decorative hole 23, which is located on the side away from the base 1 of the left mounting hole 21 and the right mounting hole 22, and is connected to the left mounting hole 21 and the right mounting hole 22.

[0101] Both the left button cover 33 and the right button cover 43 are located in the decorative hole 23 of the cover. This makes the seat heating switch look more aesthetically pleasing.

[0102] The left button cover 33 and the inner wall of the cover decorative hole 23 can be fitted with a clearance, the right button cover 43 and the inner wall of the cover decorative hole 23 can be fitted with a clearance, and the left button cover 33 and the right button cover 43 can also be fitted with a clearance.

[0103] In this way, the left button cover 33 and the right button cover 43 can fill the decorative hole 23 of the cover, which improves the aesthetics without affecting the sliding of the left heating button assembly 3 and the right heating button assembly 4, and also protects the components between the switch housing 2 and the base 1.

[0104] Alternatively, the switch housing 2 may also have decorative strip mounting holes 24, see [reference needed]. Figure 5 The decorative strip mounting hole 24 is located between the left mounting hole 21 and the right mounting hole 22, and is connected to the cover decorative hole 23. The seat heating switch also includes a decorative strip 6. (See attached image) Figure 1 The portion of the decorative strip 6 near the base 1 is located in the decorative strip mounting hole 24 and is connected to the inner wall of the decorative strip mounting hole 24. The portion of the decorative strip 6 away from the base 1 is located in the face cover decorative hole 23 and is located between the left button face cover 33 and the right button face cover 43.

[0105] The left button cover 33, the right button cover 43, and the decorative strip 6 can all be fitted with the inner wall of the decorative hole 23 of the cover with a clearance fit. The left button cover 33 and the decorative strip 6 are fitted with a clearance fit, and the right button cover 43 and the decorative strip 6 are fitted with a clearance fit.

[0106] In this way, on the one hand, the left button cover 33, the right button cover 43 and the decorative strip 6 can fill the decorative hole 23 of the cover, which will not affect the sliding of the left heating button assembly 3 and the right heating button assembly 4, while improving the aesthetics and protecting the components between the switch housing 2 and the base 1.

[0107] On the other hand, the decorative strip 6 separates the left button cover 33 and the right button cover 43, which reduces the possibility of accidentally pressing the other cover to a certain extent. For example, when the driver wants to press the left button cover 33, the presence of the decorative strip 6 reduces the possibility of the driver accidentally pressing the right button cover 43.

[0108] In one possible implementation, see Figure 1 The electrical connection structure between the left heating button assembly 3 and the circuit board 5 can be as follows: the left heating button assembly 3 also includes a left micro switch 34, which is located between the left button inner shell 32 and the circuit board 5 and is electrically connected to the circuit board 5.

[0109] The left micro switch 34 can be fixed on the circuit board 5, and its position corresponds to the position of the left button inner shell 32.

[0110] When the driver operates the device, he can press the left button cover 33. The left button cover 33 causes the left button inner shell 32 to slide along the extension direction of the left mounting hole 21. The left button inner shell 32 slides until it presses the left micro switch 34, thereby triggering the left micro switch 34. The left micro switch 34 sends a left trigger signal to the circuit board 5. After receiving the left trigger signal, the circuit board 5 sends it to the vehicle controller, which controls the left seat of the vehicle to perform the corresponding heating operation.

[0111] The electrical connection structure between the right-side heating button assembly 4 and the circuit board 5 can be as follows: See Figure 1 The right heating button assembly 4 also includes a right micro switch 44, which is located between the right button inner shell 42 and the circuit board 5 and is electrically connected to the circuit board 5.

[0112] The micro switch 44 on the right side can be fixed on the circuit board 5, and its position corresponds to the position of the inner shell 42 of the right button.

[0113] When the driver operates the vehicle, he can press the right button cover 43. The right button cover 43 causes the right button inner shell 42 to slide along the extension direction of the right mounting hole 22 until it presses the right micro switch 44, thereby triggering the right micro switch 44. The right micro switch 44 will send a right trigger signal to the circuit board 5. After receiving the right trigger signal, the circuit board 5 sends it to the vehicle controller, which controls the right seat of the vehicle to perform the corresponding heating operation.

[0114] Alternatively, in addition to using the aforementioned left microswitch 34 and right microswitch 44, a left distance sensor and a right distance sensor can also be used.

[0115] The left-side distance sensor is located between the left-side button inner shell 32 and the circuit board 5, and is electrically connected to the circuit board 5. When the driver operates the device, he can press the left-side button cover 33. The left-side button cover 33 causes the left-side button inner shell 32 to slide along the extension direction of the left-side mounting hole 21. The left-side distance sensor periodically detects the first distance between the left-side button inner shell 32 and the sensor, and sends the detected first distance to the circuit board 5. The circuit board 5 determines whether the first distance is less than a preset distance threshold. If it is less, it sends a left-side trigger signal to the vehicle controller, and the controller controls the left-side seat of the vehicle to perform the corresponding heating operation.

[0116] The right-side distance sensor is located between the right-side button inner shell 42 and the circuit board 5, and is electrically connected to the circuit board 5. When the driver operates the device, he can press the right-side button cover 43. The right-side button cover 43 causes the right-side button inner shell 42 to slide along the extension direction of the right-side mounting hole 22. The right-side distance sensor periodically detects the second distance between the right-side button inner shell 42 and the sensor, and sends the detected second distance to the circuit board 5. The circuit board 5 determines whether the second distance is less than a preset distance threshold. If it is less, it sends a right-side trigger signal to the vehicle controller, and the controller controls the right-side seat of the vehicle to perform the corresponding heating operation.

[0117] In one possible implementation, see Figure 1 The left heating button assembly 3 may also include a left light assembly and a left light guide 35. The left light assembly is electrically connected to the circuit board 5. The left light guide 35 is located in the left button inner shell 32 and is connected to the left button inner shell 32. The position of the left light guide 35 corresponds to the position of the left light assembly.

[0118] See Figure 2 The left button cover 33 has a first light-transmitting part 331, the position of which corresponds to the position of the left light guide 35.

[0119] In this way, the left light guide 35 can transmit the light emitted by the left light assembly to the first light transmission part 331 on the left button cover 33, so that the driver can see the light emitted from the first light transmission part 331 on the left button cover 33.

[0120] The first light-transmitting part 331 can be used to display the icon corresponding to the left heating button assembly on the left button cover 33. The thickness of the first light-transmitting part 331 can be less than the thickness of other parts of the left button cover 33, so that the light emitted by the left light assembly can pass through the first light-transmitting part 331. Alternatively, the first light-transmitting part 331 can be made of transparent material, while the other parts of the left button cover 33, except for the first light-transmitting part 331, are made of opaque material, and so on.

[0121] In one possible implementation, the connection structure between the left light guide 35 and the left button inner shell 32 can be: the outer side wall of the left light guide 35 has a first overlapping protrusion, and the inner side wall of the left button inner shell 32 has a first overlapping groove, with the first overlapping protrusion located in the first overlapping groove, thereby realizing the connection between the left light guide 35 and the left button inner shell 32.

[0122] Correspondingly, see Figure 1 The right heating button assembly 4 may also include a right light assembly and a right light guide 45. The right light assembly is electrically connected to the circuit board 5. The right light guide 45 is located in the right button inner shell 42 and is connected to the right button inner shell 42. The position of the right light guide 45 corresponds to the position of the right light assembly.

[0123] See Figure 2 The right button cover 43 has a second light-transmitting part 431, the position of which corresponds to the position of the right light guide 45.

[0124] In this way, the right light guide 45 can transmit the light emitted by the right light assembly to the second light transmission part 431 on the right button cover 43, so that the driver can see the light emitted from the second light transmission part 431 on the right button cover 43.

[0125] The second light-transmitting part 431 can be used to display the icon corresponding to the right heating button assembly on the right button cover 43 (this icon is different from the icon corresponding to the left heating button assembly 3; it can be a symmetrical structure, or it can be a different text icon, etc.). The thickness of the second light-transmitting part 431 can be less than the thickness of other parts of the right button cover 43, so that the light emitted by the right light assembly can pass through the second light-transmitting part 431. Alternatively, the second light-transmitting part 431 can be made of transparent material, while the other parts of the right button cover 43, except for the second light-transmitting part 431, are made of opaque material, etc.

[0126] In one possible implementation, the connection structure between the right light guide 45 and the right button inner shell 42 can be: the outer side wall of the right light guide 45 has a second overlapping protrusion, and the inner side wall of the right button inner shell 42 has a second overlapping groove, with the second overlapping protrusion located in the second overlapping groove, thereby realizing the connection between the right light guide 45 and the right button inner shell 42.

[0127] In one possible implementation, the left-side heating button assembly 3 further includes a first tactile sensor, a first heating device, and a first temperature sensor, all of which are electrically connected to the circuit board 5.

[0128] The first tactile sensor can be located on the side of the left button cover 33 away from the left button inner shell 32 and connected to the left button cover 33. The first tactile sensor is used to periodically detect the first touch signal. That is, when the user touches the left button cover 33, the first tactile sensor can detect the first touch signal and send the first touch signal to the circuit board 5.

[0129] The first heating device is connected to the left button cover 33 and is used to heat the left button cover 33.

[0130] The first temperature sensor is connected to the left button cover 33 to detect the first temperature of the left button cover 33 and send the first temperature to the circuit board 5.

[0131] The circuit board 5 is used to: control the first heating device to heat the left button cover 33 when the duration of continuously receiving the first touch signal reaches a first preset duration; control the first heating device to stop heating the left button cover 33 after receiving a left trigger signal from the left heating button assembly 3 after receiving a left trigger signal from the left heating button assembly 3 after receiving a left trigger signal from the left trigger button assembly 3 for a duration greater than or equal to the first preset duration, and send the currently detected first temperature to the vehicle controller so that the controller controls the left seat of the vehicle to be heated based on the first temperature; control the first heating device to intermittently heat the left button cover 33 after receiving a left trigger signal from the left heating button assembly 3 for a duration greater than the first preset duration, and while still receiving the first touch signal, so that the temperature of the left button cover 33 is kept at the first temperature limit until the left trigger signal from the left heating button assembly 3 is received, and the first temperature limit is sent to the vehicle controller so that the vehicle controller controls the left seat of the vehicle to be heated based on the first temperature limit.

[0132] In practice, a user can place their finger on the left button cover 33. At this time, the first tactile sensor sends a first trigger signal. When the contact time reaches the first preset time, the first heating device starts to heat the left button cover 33. The user can feel the temperature of the left button cover 33 gradually increasing. When the user believes that the temperature of the left button cover 33 has reached the temperature that the left seat wants to be heated, they can release their finger and stop contacting the left button cover 33. The first temperature sensor detects the first temperature of the left button cover 33 at this time, thereby obtaining the temperature that the user wants to heat the left seat. The first temperature is sent to the vehicle controller through the circuit board 5. The vehicle controller can control the heating of the left seat of the vehicle based on the first temperature.

[0133] When a user's finger is placed on the left button cover 33 for too long, causing the first temperature of the left button cover 33 to reach the first temperature limit, the first heating device will be controlled to start heating the left button cover 33 intermittently to avoid overheating and burns to the user. If the user's finger continues to be in contact with the left button cover 33 during this process until the user presses the left heating button assembly 3, causing the left button assembly 3 to send a left trigger signal, the circuit board 5 can directly send the first temperature limit to the vehicle controller so that the controller can control the left seat of the vehicle to be heated based on the first temperature limit.

[0134] In one possible implementation, the controller can control the heating of the left-side seat of the vehicle based on the first temperature by directly controlling the left-side seat of the vehicle to heat up to the first temperature.

[0135] Alternatively, the controller can calculate the sum of the first temperature and the preset supplementary temperature, and then control the heating of the left-side seat of the vehicle to the sum of the first temperature and the preset supplementary temperature. This setting is because there are clothing, cushions, or other items between the user and the left-side seat, so the temperature felt by the user on the left-side seat may be relatively low. When the left-side seat is heated to the sum of the first temperature and the preset supplementary temperature, the temperature felt by the user on the left-side seat will be closer to the first temperature felt by their fingers, thereby improving the user experience.

[0136] The preset supplementary temperature can be set according to experiments or needs, and the specific value is not limited in this embodiment.

[0137] Similarly, the controller can control the left-side seat of the vehicle to be heated based on the first temperature limit by directly controlling the left-side seat of the vehicle to be heated to the first temperature limit.

[0138] Alternatively, the controller can calculate the sum of the first temperature limit and the preset supplementary temperature, and then control the left seat of the vehicle to heat up to the sum of the first temperature limit and the preset supplementary temperature.

[0139] In one possible implementation, the left heating button assembly 3 may include multiple left light assemblies and a left light guide 35. Correspondingly, the left button cover 33 may have multiple first light transmission parts 331. Each left light assembly corresponds to a left light guide 35 and a first light transmission part 331. The left light guide 35 is located between the left light assembly and the first light transmission part 331 and is used to transmit the light emitted by the left light assembly to the first light transmission part 331.

[0140] The circuit board 5 is used to: control multiple left-side light components to light up based on the received first temperature after the first heating device heats the left-side button cover 33.

[0141] Among them, multiple first light-transmitting parts 331 can be arranged in a straight line on the left button cover 33, and correspondingly, multiple left light guides 35 are also arranged in the same straight line direction in the left button inner shell 32, and multiple left light components are also arranged in the same straight line direction on the circuit board 5.

[0142] The method for circuit board 5 to control the illumination of multiple left-side light components based on a first temperature can be as follows: The lower limit of the first temperature corresponding to the illumination of each left-side light component is pre-stored, and the lower limits of the first temperature corresponding to multiple left-side light components increase sequentially along the straight line extending in that direction. During the heating process of the left-side button cover 33 by the first heating device, whenever one of the multiple lower limits of the first temperature is reached, the left-side light component corresponding to that lower limit is controlled to illuminate.

[0143] In this way, when the first heating device heats the left button cover 33, multiple left-side light components will light up sequentially as the first temperature increases. The user can see that multiple first light-transmitting parts 331 on the left button cover 33 light up sequentially as the temperature increases. In this way, in addition to feeling the temperature on the left button cover 33 with their fingers, the user can also judge the current temperature by the display on the multiple first light-transmitting parts 331 on the left button cover 33.

[0144] Correspondingly, in one possible implementation, the right-side heating button assembly 4 also includes a second tactile sensor, a second heating device, and a second temperature sensor, all of which are electrically connected to the circuit board 5.

[0145] The second tactile sensor can be located on the side of the right button cover 43 away from the right button inner shell 42 and connected to the right button cover 43. The second tactile sensor is used to periodically detect the second touch signal. That is, when the user touches the right button cover 43, the second tactile sensor can detect the second touch signal and send the second touch signal to the circuit board 5.

[0146] The second heating device is connected to the right button cover 43 and is used to heat the right button cover 43.

[0147] The second temperature sensor is connected to the right button cover 43 and is used to detect the second temperature of the right button cover 43 and send the second temperature to the circuit board 5.

[0148] The circuit board 5 is used to: control the second heating device to heat the right button cover 43 when the duration of continuously receiving the second touch signal reaches the second preset duration; control the second heating device to stop heating the right button cover 43 after receiving the right trigger signal of the right heating button assembly 4 after receiving the right trigger signal of the right heating button assembly 4 after receiving the right trigger signal of the right heating button assembly 4 for a duration greater than or equal to the second preset duration, and send the currently detected second temperature to the vehicle controller so that the controller controls the right seat of the vehicle to be heated based on the second temperature; control the second heating device to intermittently heat the right button cover 43 after receiving the right trigger signal of the right heating button assembly 4 for a duration greater than the second preset duration, and still continuously receiving the second touch signal, so that the temperature of the right button cover 43 is kept at the second temperature limit until the right trigger signal of the right heating button assembly 4 is received, and the second temperature limit is sent to the vehicle controller so that the vehicle controller controls the right seat of the vehicle to be heated based on the second temperature limit.

[0149] In practice, the user can place their finger on the right button cover 43. At this time, the second tactile sensor sends a second trigger signal. When the contact time reaches the second preset time, the second heating device starts to heat the right button cover 43. The user can feel the temperature of the right button cover 43 gradually increasing. When the user believes that the temperature of the right button cover 43 has reached the temperature that the right seat wants to be heated, they can release their finger and stop contacting the right button cover 43. The second temperature sensor detects the second temperature of the right button cover 43 at this time, thereby obtaining the temperature that the user wants to heat the right seat. The second temperature is sent to the vehicle controller through the circuit board 5. The vehicle controller can control the heating of the right seat of the vehicle based on the second temperature.

[0150] If the user's finger is placed on the right button cover 43 for too long, causing the second temperature of the right button cover 43 to reach the second temperature limit, the second heating device will be controlled to start heating the right button cover 43 intermittently to avoid overheating and burns to the user. If the user's finger continues to be in contact with the right button cover 43 during this process until the user presses the right heating button assembly 4, causing the right button assembly 4 to send a right trigger signal, the circuit board 5 can directly send the second temperature limit to the vehicle controller so that the controller can control the right seat of the vehicle to be heated based on the second temperature limit.

[0151] In one possible implementation, the controller can control the right-side seat of the vehicle to be heated based on the second temperature by directly controlling the right-side seat of the vehicle to be heated to the second temperature.

[0152] Alternatively, the controller can calculate the sum of the second temperature and the preset supplementary temperature, and then control the right-side seat of the vehicle to heat up to the sum of the second temperature and the preset supplementary temperature. This setting is because there are clothing, cushions, or other items between the user and the right-side seat, so the temperature felt by the user may be relatively low. When the right-side seat is heated to the sum of the second temperature and the preset supplementary temperature, the temperature felt by the user through the right-side seat is closer to the second temperature felt by their fingers, thereby improving the user experience.

[0153] The preset supplementary temperature can be set according to experiments or needs, and the specific value is not limited in this embodiment.

[0154] Similarly, the controller can control the right-side seat of the vehicle to be heated based on the second temperature limit by directly controlling the right-side seat of the vehicle to be heated to the second temperature limit.

[0155] Alternatively, the controller can calculate the sum of the second upper temperature limit and the preset supplementary temperature, and then control the right-side seat of the vehicle to be heated to the sum of the second upper temperature limit and the preset supplementary temperature.

[0156] In one possible implementation, the right heating button assembly 4 may include multiple right light assemblies and a right light guide 45. Correspondingly, the right button cover 43 may have multiple second light transmission portions 431. Each right light assembly corresponds to a right light guide 45 and a second light transmission portion 431. The right light guide 45 is located between the right light assembly and the second light transmission portion 431 and is used to transmit the light emitted by the right light assembly to the second light transmission portion 431.

[0157] The circuit board 5 is used to: control multiple right-side light components to light up based on the received second temperature after the second heating device is used to heat the right-side button cover 43.

[0158] Among them, multiple second light-transmitting parts 431 can be arranged in a straight line on the right button cover 43, and correspondingly, multiple right light guides 45 are also arranged in the same straight line direction in the right button inner shell 42, and multiple right light components are also arranged in the same straight line direction on the circuit board 5.

[0159] The method for circuit board 5 to control the illumination of multiple right-side light components based on a second temperature can be as follows: The lower limit of the second temperature corresponding to the illumination of each right-side light component is pre-stored, and the lower limits of the second temperature corresponding to multiple right-side light components increase sequentially along the straight line extending in that direction. During the heating process of the right-side button cover 43 by the second heating device, whenever one of the lower limits of the multiple lower temperatures is reached, the right-side light component corresponding to that lower limit is controlled to illuminate.

[0160] In this way, when the second heating device heats the right button cover 43, multiple right-side light components will light up sequentially as the second temperature increases. The user can see that multiple second light-transmitting parts 431 on the right button cover 43 light up sequentially as the temperature increases. In this way, in addition to feeling the temperature on the right button cover 43 with their fingers, the user can also judge the current temperature by the display on the multiple second light-transmitting parts 431 on the right button cover 43.

[0161] In one possible implementation, see Figure 1 The seat heating switch also includes a circuit board protective sleeve 7, which is fitted on the side of the circuit board 5 away from the base 1 and on the outside. The circuit board protective sleeve 7 can be made of any insulating material, thereby protecting the circuit board 5.

[0162] In one possible implementation, see Figure 1 The circuit board 5 has a surface mount pin 51 on the side near the base 1. The base 1 has a connection hole in which the surface mount pin 51 is located for electrical connection with the vehicle controller.

[0163] In one possible implementation, the structure on the switch housing 2 for connecting to the vehicle's connector can be: see [link to relevant documentation]. Figure 10 The outer wall of the switch housing 2 has a first snap-fit ​​25, which is used to engage with a first snap-fit ​​hole on the vehicle mounting part.

[0164] In one possible implementation, see Figure 10The switch housing 2 also has two first positioning ribs 26 and two second positioning ribs 27. The two first positioning ribs 26 are respectively located on two oppositely arranged first outer walls n of the switch housing 2 and are symmetrically arranged based on the central plane m of the switch housing 2. The two second positioning ribs 27 are respectively located on two oppositely arranged first outer walls n and are symmetrically arranged based on the central plane m of the switch housing 2. The length of the second positioning ribs 27 in the direction perpendicular to the first outer wall n is different from the length of the first positioning ribs 26 in the direction perpendicular to the first outer wall n. The first positioning ribs 26 are used to engage with the first positioning groove on the vehicle mounting part, and the second positioning ribs 27 are used to engage with the second positioning groove on the vehicle mounting part.

[0165] In this way, since the length of the second positioning rib 27 in the direction perpendicular to the first outer wall n is different from the length of the first positioning rib 26 in the direction perpendicular to the first outer wall n, the shape and size of the first positioning rib 26 are adapted to the first mounting groove, and the shape and size of the second positioning rib 27 are adapted to the second mounting groove. Therefore, if the two first outer walls are installed in reverse when installing the seat heating switch, the two first positioning ribs 26 and the two second positioning ribs 27 cannot be engaged with the two first positioning grooves and the two second positioning grooves. Therefore, the above structure can avoid incorrect installation.

[0166] In one possible implementation, the switch housing 2 may also have positioning ribs on other outer walls besides the first outer wall, which engage with other positioning slots on the mounting component, thereby improving the installation stability of the seat heating switch.

[0167] The connection structure between the seat heating switch and the vehicle mounting components can also be any other reasonable structure, and this disclosure does not limit this.

[0168] This disclosure also provides a vehicle that includes a mounting component and a seat heating switch as described above, the seat heating switch being connected to the mounting component.

[0169] The seat heating switch and the mounting component can be connected through the first buckle 25 and the first snap hole, the first positioning rib 26 and the first positioning groove, and the second positioning rib 27 and the second positioning groove, as described above, which will not be repeated here.

[0170] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0171] This disclosure provides a seat heating switch. Since the shape of the left mounting hole 21 on the cross section perpendicular to the extension direction of the left mounting hole 21 is asymmetrical, and the shape of the right mounting hole 22 on the cross section perpendicular to the extension direction of the right mounting hole 22 is also asymmetrical, and the left mounting hole 21 and the right mounting hole 22 are symmetrically arranged based on the central plane m of the switch housing 2, the left heating button assembly 3 cannot be installed into the right mounting hole 22, and the right heating button assembly 4 cannot be installed into the left mounting hole 21. This avoids the problem of incorrect installation of the left heating button assembly 3 and the right heating button assembly 4, thereby improving installation efficiency and convenience.

[0172] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
