Description

Technical Field

[0001] This invention relates to the field of vehicle parts technology, and in particular to a vehicle seat table adjustment device and adjustment method. Background Technology

[0002] Seats are an important part of a vehicle and directly affect the passenger's riding experience. There are usually tables behind the seats. The tables can be opened and folded away relative to the seats to meet the reading, working or placing of items needs of rear passengers.

[0003] Because the interior of the vehicle is dimly lit, it is inconvenient for passengers to read or work. If lights are installed on the roof, on the one hand, the installation position is too high and there is a certain distance between the light source and the table, which may result in insufficient lighting in the area where the light falls on the table, failing to meet the needs of passengers. On the other hand, the light may affect the driver and surrounding passengers, resulting in a poor riding experience.

[0004] Installing lights on the seats can ensure adequate illumination of the tray tables. These lights typically have separate switches, allowing them to be turned on when needed. However, this method requires mounting the lights and switches on the seats, which increases development and placement costs, especially in situations with limited space. Furthermore, the overall integration is poor. Separate switches also make it easy to forget to turn off the lights, particularly when passengers are rushing off. Accustomed to the brightness of the lights, they are unlikely to notice that they are still on, leading to energy waste and impacting the vehicle's range. Therefore, this method has certain limitations. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a vehicle seat table adjustment device and adjustment method, which can provide lighting to the table and synchronize the lighting and table adjustment. It can determine whether the light is off by the status of the table. It has a simple structure, is easy to adjust, has a high degree of integration, and is easy to arrange.

[0006] This invention provides a vehicle seat table adjustment device, installed on a seat body, for adjusting the table at the rear of the seat body, comprising: The lighting unit is capable of providing lighting to the tabletop; The locking part, which cooperates with the tabletop, enables the tabletop to be in an open state and a retracted state. An adjustment unit is provided for controlling the switching on and off of the lighting unit and the unlocking of the locking unit. When the locking unit is unlocked, the lighting unit is turned on, and when the locking unit is locked, the adjustment unit turns off the lighting unit.

[0007] In one embodiment, the adjustment unit includes an adjustment switch, which is movably mounted on the seat body and partially exposed thereout. The lighting unit is mounted on the adjustment switch to provide lighting to the tabletop via the adjustment switch.

[0034] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0035] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0036] Seats are an important part of a vehicle and directly affect the passenger's riding experience. There are usually tables behind the seats. The tables can be opened and folded away relative to the seats to meet the reading, working or placing of items needs of rear passengers.

[0037] Because the interior of the vehicle is dimly lit, it is inconvenient for passengers to read or work. If lights are installed on the roof, on the one hand, the installation position is too high and there is a certain distance between the light source and the table, which may result in insufficient lighting in the area where the light falls on the table, failing to meet the needs of passengers. On the other hand, the light may affect the driver and surrounding passengers, resulting in a poor riding experience.

[0038] Installing lights on the seats can ensure adequate illumination of the tray tables. These lights typically have separate switches, allowing them to be turned on when needed. However, this method requires mounting the lights and switches on the seats, which increases development and placement costs, especially in situations with limited space. Furthermore, the overall integration is poor. Separate switches also make it easy to forget to turn off the lights, particularly when passengers are rushing off. Accustomed to the brightness of the lights, they are unlikely to notice that they are still on, leading to energy waste and impacting the vehicle's range. Therefore, this method has certain limitations.

[0039] In some application scenarios, if a passenger accidentally touches the lights when getting off the vehicle, the lights will remain on. Existing technology has the problem that there is no obvious warning after the passenger accidentally touches the lights, which further affects the user experience of the vehicle.

[0040] like Figure 1 As shown, the vehicle seat table adjustment device proposed in this invention is installed on the seat body 100 and is used to adjust the table 101 at the rear of the seat body 100 so that the table 101 has an open state and a retracted state relative to the seat body 100, and is used to provide lighting to the table 101.

[0041] like Figure 2 As shown, the vehicle seat table adjustment device proposed in this invention includes: Lighting unit 10 is capable of providing lighting to tabletop 101. The locking part 20, which cooperates with the tabletop 101, enables the tabletop 101 to have an open state and a retracted state. Specifically, when the locking part 20 is unlocked, the tabletop 101 is in the open state, and when the locking part 20 is locked, the tabletop 101 is in the retracted state. The adjustment unit 30 is used to control the switching on and off of the lighting unit 10 and the unlocking of the locking unit 20. When the locking unit 20 is unlocked, the lighting unit 10 is turned on, and when the locking unit 20 is locked, the adjustment unit 30 turns off the lighting unit 10.

[0042] The lighting unit 10 provides illumination when passengers use the table 101, making it easier for passengers to read or work, thus improving the passenger's table 101 user experience and compensating for insufficient lighting inside the vehicle. The adjustment unit 30 is used to control the on / off switch of the lighting unit 10 and to control the unlocking of the locking unit 20. This facilitates the integration of the control of the lighting unit 10 and the control of the table 101, improves the overall structural integration, and makes it easier to arrange within the limited space of the seat body 100. It also helps to reduce the cost of developing and arranging individual parts. The adjustment unit 30 can turn on the lighting unit 10 while the table 101 is open, making it convenient to use the table 101. The adjustment unit 30 will only turn off the lighting unit 10 when the passenger folds the table 101 for storage. The table 101 not only provides a functional function but also has a very clear indication function. Passengers can judge whether the light is off based on the status of the table 101. When passengers get off the vehicle, they can easily notice that the table 101 is not closed. This invention enables synchronous control of the table 101 and the lighting unit 10, eliminating the need for additional light-off operations and effectively solving the problem of passengers forgetting to turn off the lights. Especially for new energy vehicles, it can effectively avoid the problem of reduced range caused by passengers forgetting to turn off the lights. The overall structure is simple and easy to operate, which helps to enhance the technological and design sense of the vehicle.

[0043] Furthermore, even if a passenger accidentally touches the adjustment unit 30 while in the vehicle, the table 101 will open simultaneously to remind the passenger of the accidental touch, which helps to improve the user experience of the vehicle and effectively avoids accidental touches.

[0044] In one embodiment, such as Figure 3 As shown, the lighting unit 10 includes a lamp panel 11 and a lampshade 12. The lamp panel 11 is used to provide a light source, and the lampshade 12 is installed on the outside of the lamp panel 11 to cover and protect the lamp panel 11. It can both allow the light emitted by the lamp panel 11 to pass through the lampshade 12 and illuminate the tabletop 101, and prevent the lamp panel 11 from being directly exposed to the outside and easily damaged.

[0045] In this example of Embodiment 1, as Figure 3As shown, the lamp panel 11 is equipped with LED beads 111, which serve as a light source to provide illumination. Understandably, the number, color, and model of the LED beads 111 can be selected according to actual lighting requirements.

[0046] In this example of Embodiment 1, the lamp board 11 is a PCB (Printed Circuit Board).

[0047] In this example of Embodiment 1, combined with Figure 3 and Figure 4 The lampshade 12 has a textured structure 121 at one end near the lamp panel 11. The textured structure 121 is used to reflect light so that the light emitted by the lamp panel 11 shines on the tabletop 101, ensuring that the tabletop 101 has sufficient illumination.

[0048] In one embodiment, combined with Figure 3 and Figure 4 The adjustment unit 30 includes an adjustment switch 31, which is movably mounted on the seat body 100, as shown in the figure. Figure 1 The adjustment switch 31 is partially exposed on the seat body 100. The adjustment switch 31 controls the on / off state of the lighting unit 10 and the unlocking state of the locking unit 20. The lighting unit 10 is mounted on the adjustment switch 31 to provide illumination to the tabletop 101. More specifically, the lampshade 12 is exposed on the seat body 100 through the adjustment switch 31, and the light emitted from the lamp panel 11 passes through the lampshade 12, shines through the adjustment switch 31, and illuminates the tabletop 101. This design improves the overall aesthetics of the seat body 100 and effectively avoids the problem of increased structural gaps in the seat body 100.

[0049] In this first embodiment, the lampshade 12 and the adjustment switch 31 are formed by a two-color injection molding process.

[0050] In this example of Embodiment 1, as Figure 3 As shown, the lighting unit 10 also includes a lamp holder 13, which is located on the side of the lamp panel 11 away from the lamp cover 12. The lamp holder 13 includes a receiving cavity 131 for mounting the lamp panel 11. The lamp holder 13 is connected to the side of the adjustment switch 31 near the lamp panel 11 to encapsulate the lamp panel 11. The lamp holder 13 and the adjustment switch 31 work together to provide a light shielding function, so that the light emitted by the lamp panel 11 can only pass through the lamp cover 12, preventing the light emitted by the lamp panel 11 from passing through other areas and affecting the lighting effect and user experience.

[0051] For example, combined Figure 3 and Figure 4The adjusting switch 31 has a protruding positioning member 311 at one end near the lamp plate 11. The positioning member 311 can cooperate with the inner wall of the receiving cavity 131. When the lamp holder 13 is connected to the adjusting switch 31, the lamp holder 13 is nested on the positioning member 311 through the receiving cavity 131, and the positioning member 311 is in contact with the inner wall of the receiving cavity 131. The cooperation between the positioning member 311 and the receiving cavity 131 can realize the quick positioning and installation of the adjusting switch 31 and the lamp holder 13, which is beneficial to improving assembly efficiency.

[0052] Furthermore, such as Figure 4 As shown, the positioning member 311 protrudes from the outer periphery of the lampshade 12 to install the lamp holder 13 in a position that mates with the lampshade 12, so that the lamp plate 11 can mate with the lampshade 12, thereby achieving effective lighting of the tabletop 101.

[0053] Furthermore, such as Figure 4 As shown, the adjustment switch 31 has an insert 312 protruding at one end near the lamp plate 11, and the lamp holder 13 has a groove 132. When the lamp holder 13 is fitted onto the positioning member 311 through the receiving cavity 131, the insert 312 is engaged in the groove 132. The fit between the insert 312 and the groove 132 can further improve the connection quality between the lamp holder 13 and the adjustment switch 31, and ensure the stability and firmness of the assembly.

[0054] For example, such as Figure 4 As shown, the adjusting switch 31 has a first limiting member 313 and a second limiting member 314 protruding at one end near the lamp plate 11. The first limiting member 313 and the second limiting member 314 are spaced apart in the vertical direction, and both sets of the first limiting member 313 and the second limiting member 314 are located outside the positioning member 311 in the horizontal direction. The lamp holder 13 has guide members 133 protruding at both ends. When the lamp holder 13 is connected to the adjusting switch 31, the guide member 133 is engaged between the first limiting member 313 and the second limiting member 314. The guide member 133 cooperates with the first limiting member 313 and the second limiting member 314 to play both the installation guiding role and the vertical fixing role of the lamp holder 13.

[0055] Furthermore, such as Figure 4 As shown, the two second limiting members 314 have a locking member 315 protruding at one end that is close to each other, and the lamp holder 13 has a mating member 134 protruding at both ends. When the lamp holder 13 is connected to the adjustment switch 31, the locking member 315 can engage with the mating member 134 to fix the lamp holder 13 to the adjustment switch 31.

[0056] For example, such as Figure 3As shown, a positioning rib 135 protrudes from the receiving cavity 131, and a positioning groove 112 is provided on the lamp plate 11. When the lamp plate 11 is installed in the receiving cavity 131, the positioning rib 135 is engaged in the positioning groove 112. The positioning rib 135 and the positioning groove 112 cooperate to realize the rapid positioning and installation of the lamp plate 11, which is conducive to improving assembly efficiency.

[0057] For example, the adjustment switch 31 and the lamp holder 13 can also be detachably connected by means of screws, for example, to facilitate subsequent maintenance and repair, or the adjustment switch 31 and the lamp holder 13 can also be non-detachably connected by means of adhesive, for example, to improve structural stability.

[0058] In this example of Embodiment 1, combined with Figure 3 and Figure 4 The adjustment switch 31 is configured to be pressed relative to the seat body 100. The adjustment switch 31 has a first mounting arm 316 at one end near the light panel 11. The first mounting arm 316 is slidably fitted to the seat body 100 and is used to movably mount the adjustment switch 31 to the seat body 100.

[0059] For example, the number of first mounting arms 316 is set to two, and they are located on both sides of the adjustment switch 31 in the length direction to ensure the pressing feel and pressing stability of the adjustment switch 31.

[0060] For example, such as Figure 3 As shown, the adjustment switch 31 has an elastic element 317 connected to one end near the light panel 11. The elastic element 317 cooperates with the first mounting arm 316 to movably mount the adjustment switch 31 onto the seat body 100. The elastic element 317 is configured to extend along the front-rear direction of the vehicle so that it can generate elastic deformation in the front-rear direction when the adjustment switch 31 is pressed, so that the adjustment switch 31 can be reset.

[0061] Furthermore, the elastic element 317 is a spring.

[0062] Furthermore, the number of elastic elements 317 is set to two, and the two elastic elements 317 are respectively arranged adjacent to the two first mounting arms 316 to ensure the stability of the adjustment switch 31 reset.

[0063] In one embodiment, such as Figure 5 As shown, the locking part 20 includes a locking tongue 21 and a reset member 22, which are combined with Figure 1 The tabletop 101 has a locking groove 102. The locking tongue 21 is installed on the seat body 100 through a reset member 22. The reset member 22 is used to reset the locking tongue 21. When the locking tongue 21 is in the locking groove 102, the tabletop 101 is in the retracted state. When the locking tongue 21 is disengaged from the locking groove 102, the tabletop 101 is in the open state.

[0064] In one embodiment, such as Figure 5 As shown, the adjustment unit 30 includes a transmission member 32 and a lighting control member 33. The locking part 20 is connected to the transmission member 32, meaning that the locking part 20 and the transmission member 32 can transmit to each other. When one of them moves, it can transmit to the other, causing the other to move synchronously. The lighting control member 33 is installed on one side of the transmission member 32 and cooperates with the lighting unit 10 to control the opening and closing of the lighting unit 10. The transmission member 32 is connected to the adjustment switch 31. The transmission member 32 is configured to move under the drive of the adjustment switch 31 to unlock the locking part 20, thereby putting the tabletop 101 in the open state and causing the lighting control member 33 to control the lighting unit 10 to turn on. When the tabletop 101 is in the retracted state, the transmission member 32 is configured to move under the drive of the locking part 20 to cause the lighting control member 33 to control the lighting unit 10 to turn off.

[0065] In this example of Embodiment 1, as Figure 5 As shown, and refer to Figure 4 The transmission component 32 includes a sliding component 321. The regulating switch 31 is provided with a guide ramp 318. The sliding component 321 contacts and slides with the guide ramp 318. The guide ramp 318 is configured to enable the sliding component 321 to move along the unlocking direction and / or locking direction of the locking part 20.

[0066] For example, such as Figure 4 As shown, the guide ramp 318 is provided on the second limiting member 314 so as to make reasonable use of the structure of the adjusting switch 31 and make the overall layout compact.

[0067] For example, such as Figure 4 As shown, when the locking part 20 can unlock and / or lock in the vertical direction, more specifically, the locking tongue 21 moves upward to disengage from the locking groove 102. At this time, the locking part 20 is unlocked and the table 101 is in the open state. When the passenger closes the table 101, the table 101 will push the locking tongue 21 upward until the locking tongue 21 is accommodated in the locking groove 102 to realize the storage of the table 101. In this solution, the guide ramp 318 is configured to have a height change in the height direction of the vehicle, and the height of the upper end surface of the guide ramp 318 gradually increases from front to back. When the adjustment switch 31 is pressed in the front-back direction, the sliding member 321 can contact and slide with the upper end surface of the guide ramp 318, thereby being able to move in the vertical direction and drive the locking tongue 21 to move in the vertical direction.

[0068] This configuration allows the forward and backward control of the adjustment switch 31 to be converted into the up and down control of the locking tongue 21 through the cooperation of the guide ramp 318 and the sliding member 321. The up and down movement of the transmission member 32 is used to control the lighting control member 33. Through the reversing control, the table 101 and the lighting unit 10 can be synchronously controlled through the adjustment switch 31. There is no need to install the control components of the table 101 and the lighting unit 10 separately. It can be installed in the limited space of the seat body 100, reducing the space occupied by the seat body 100 and improving the overall integration.

[0069] For example, such as Figure 6 As shown, the transmission component 32 includes a matching groove 322, and the upper part of the locking tongue 21 is accommodated in the matching groove 322 to increase the contact area between the transmission component 32 and the locking tongue 21, thereby ensuring stable and efficient mutual transmission between the transmission component 32 and the locking tongue 21.

[0070] For example, combined Figure 5 and Figure 6 The locking tongue 21 is provided with a first guide groove 211, and the transmission member 32 is provided with a second guide groove 323. When the upper part of the locking tongue 21 is accommodated in the matching groove 322, the first guide groove 211 and the second guide groove 323 are connected. The transmission member 32 and the locking part 20 can be movably installed to the seat body 100 through the first guide groove 211 and the second guide groove 323.

[0071] For example, combined Figure 5 and Figure 6 The transmission component 32 is provided with a second mounting arm 324, which is used to movably mount the transmission component 32 to the seat body 100.

[0072] Furthermore, the number of second mounting arms 324 is set to two to ensure the stability and reliability of the movement of the transmission component 32.

[0073] In this example of Embodiment 1, as Figure 5 As shown, the transmission member 32 also includes an abutment member 325. When the transmission member 32 moves along the unlocking direction and / or locking direction of the locking part 20 through the cooperation of the sliding member 321 and the guide ramp 318, the abutment member 325 moves relative to the lighting control member 33 and can contact the lighting control member 33 so as to realize the switching control of the lighting part 10 through the lighting control member 33.

[0074] For example, such as Figure 7As shown, the lighting control unit 33 includes a lamp control board 331 and a lighting switch 332. The lighting switch 332 is mounted on the lamp control board 331. The lamp control board 331 is communicatively connected to the lighting unit 10 so as to realize the control of the lighting unit 10. The abutment member 325 can move with the transmission member 32 to contact the lighting switch 332 so as to realize the switching control of the lighting unit 10 through the cooperation of the lighting switch 332 and the lamp control board 331.

[0075] As a feasible approach, combining Figure 5 and Figure 6 The distance between the abutment 325 and the lighting switch 332 gradually decreases in the unlocking direction and / or locking direction of the locking part 20, so that the distance between the abutment 325 and the lighting switch 332 continuously decreases until they contact each other during the movement of the transmission member 32.

[0076] More specifically, when the locking part 20 can be unlocked and / or locked in the vertical direction, the abutment 325 can move up and down through the cooperation of the guide ramp 318 and the sliding part 321. The end face of the abutment 325 near the lighting switch 332 is configured such that the distance between the end face and the lighting switch 332 gradually decreases from top to bottom, that is, the end face is inclined and gradually approaches the lighting switch 332 from top to bottom. When the abutment 325 moves upward, it gradually moves to contact the lighting switch 332 so as to realize the switching control of the lighting part 10 through the lighting switch 332.

[0077] Furthermore, the lighting control component 33 also includes a protective housing, with the lighting control board 331 installed inside the protective housing and the lighting switch 332 exposed outside the protective housing. The protective housing can protect the lighting control board 331.

[0078] As a feasible approach, such as Figure 7 As shown, the protective shell includes a sleeve 333 and an insert 334. The insert 334 can be fitted into the sleeve 333 to form an installation space for mounting the lighting control board 331. One of the sleeve 333 and the insert 334 has a limiting groove 335, and the other has a protruding locking block 336. When the sleeve 333 and the insert 334 are connected, the locking block 336 is engaged in the limiting groove 335 to achieve quick positioning and installation of the sleeve 333 and the insert 334. As another feasible method, the sleeve 333 and the insert 334 can also be detachably connected by means such as screws to facilitate subsequent maintenance and repair. Alternatively, the sleeve 333 and the insert 334 can also be non-detachably connected by means such as adhesive to improve structural stability.

[0079] As a feasible approach, such as Figure 7As shown, the lighting control board 331 has a positioning groove 112 as described on the lighting board 11, and the housing 333 has a positioning rib 135 protruding from the receiving cavity 131 as described, so as to realize the quick positioning and installation of the lighting control board 331. The size, quantity and other parameters of the positioning groove 112 and the positioning rib 135 can be flexibly adjusted according to actual needs.

[0080] Furthermore, such as Figure 7 As shown, the lighting control component 33 also includes a protective sleeve 337, which is installed on the lighting switch 332 for direct contact with the abutment 325. Since the contact between the abutment 325 and the lighting switch 332 is achieved through mechanical movement, the lighting switch 332 is at risk of wear and aging after long-term use. The protective sleeve 337 can protect the lighting switch 332 and help extend its service life. In subsequent maintenance and repair, only the protective sleeve 337 needs to be replaced.

[0081] In one embodiment, combined with Figure 2 and Figure 8 The vehicle seat table adjustment device proposed in this invention also includes an integration part 40, which includes a base 41. The aforementioned lighting part 10, locking part 20 and adjustment part 30 are all directly or indirectly installed on the base 41. The integration part 40 can integrate the various components into one, which is beneficial to improving the integration of the entire adjustment device and making it easier to install the various components onto the seat body 100.

[0082] As a viable approach, the base 41 can be detachably connected to the seat body 100 by means of screws, for example, to facilitate subsequent maintenance and repair, or it can be non-detachably connected to the seat body 100 by means of adhesive, to improve structural stability.

[0083] In this example of Embodiment 1, as Figure 8 As shown, and in combination Figure 3 and Figure 4 The base 41 has a first through groove 411 for installing the adjustment switch 31. The first mounting arm 316 passes through the first through groove 411 and can slide with the first through groove 411 during the pressing of the adjustment switch 31, so that the adjustment switch 31 can be movably installed on the base 41 and movably installed on the seat body 100 through the base 41.

[0084] For example, such as Figure 4 As shown, a stop 319 is provided at one end of the first mounting arm 316. The stop 319 is located at the end of the first mounting arm 316 near the base 41. The stop 319 is used to limit the movement and prevent the end of the first mounting arm 316 from passing through the first through groove 411 during the sliding process.

[0085] For example, the first slot 411 is opened along the front-rear direction of the vehicle, and passengers can press the adjustment switch 31 in the front-rear direction to adjust the table 101. Understandably, the installation position and adjustment direction of the entire adjustment device can also be adjusted according to actual needs.

[0086] In this example of Embodiment 1, combined with Figure 5 , Figure 8 and Figure 9 The base 41 has a second through groove 412 for mounting the transmission component 32. The second mounting arm 324 passes through the second through groove 412 and can slide with the second through groove 412 during the movement of the transmission component 32, so that the transmission component 32 can be movably mounted on the base 41 and movably mounted on the seat body 100 through the base 41.

[0087] For example, such as Figure 5 As shown, one end of the second mounting arm 324 is provided with the aforementioned stop 319. The stop 319 is located at the end of the second mounting arm 324 near the base 41. The stop 319 is used to limit the movement and prevent the end of the second mounting arm 324 from passing through the second through groove 412 during the sliding process.

[0088] In this example of Embodiment 1, combined with Figure 6 , Figure 8 and Figure 9 A guide bar 413 protrudes from the base 41. The locking tongue 21 and the transmission member 32 are movably connected to the guide bar 413 through the first guide groove 211 and the second guide groove 323, respectively, and can move along the guide bar 413. It can be understood that the extension direction of the guide bar 413 is the unlocking direction and / or locking direction of the locking part 20.

[0089] In this example of Embodiment 1, combined with Figure 7 and Figure 8 The base 41 is also provided with a third through groove 414 that cooperates with the lighting control component 33. The outer wall of the housing 333 is provided with a through piece 338. When the lighting control component 33 is installed on the base 41, the through piece 338 is locked in the third through groove 414.

[0090] In one embodiment, combined with Figure 2 and Figure 10 The vehicle seat table adjustment device proposed in this invention also includes a control unit 50, which is communicatively connected to the lighting unit 10 and to the vehicle's main control unit, so as to realize one or more adjustment controls of the lighting unit 10 in terms of switching, brightness and color through the main control unit.

[0091] In this example of Embodiment 1, as Figure 10As shown, the control unit 50 includes a housing and a control board 51. The control board 51 is installed inside the housing, and the housing can protect the control board 51. The control board 51 is used to communicate with the vehicle body control system and with the lighting unit 10. More specifically, the control board 51 can communicate with the lamp panel 11, and thus the lighting unit 10 can be controlled through the vehicle body control system.

[0092] For example, the control board 51 uses a PCB that integrates at least one of the functions of the lighting unit 10, namely, switching, brightness and color.

[0093] For example, such as Figure 10 As shown, the outer casing includes a first housing 52 and a second housing 53, which are assembled to form a cavity for accommodating the control board 51, thereby achieving the encapsulation of the control board 51.

[0094] Furthermore, such as Figure 10 As shown, the first housing 52 has a connecting ear 521 protruding at one end near the second housing 53, and the second housing 53 has a connecting groove 531. When the first housing 52 and the second housing 53 are connected, the connecting ear 521 is engaged in the connecting groove 531.

[0095] One of the connecting ear 521 and the connecting groove 531 has a slot 522, and the other has a protruding locking piece 532. When the connecting ear 521 is locked in the connecting groove 531, the locking piece 532 is locked in the slot 522, which can realize the connection and fixation of the first housing 52 and the second housing 53. The structure is simple and the assembly is convenient.

[0096] Furthermore, such as Figure 11 As shown, the second housing 53 has a positioning post 533 protruding at one end near the control board 51, and the control board 51 has a positioning hole 511. When the control board 51 is installed in the housing, the control board 51 is fitted onto the positioning post 533 through the positioning hole 511. This arrangement can improve the installation efficiency of the control board 51 and ensure the accurate positioning of the control board 51.

[0097] The second housing 53 has a protruding fixing post 534 near the control plate 51. The control plate 51 has a fixing hole 512, which mates with the fixing post 534. Figure 10 The fastener 523 passes through the fixing hole 512 and is connected to the fixing post 534 to fix the control plate 51 between the first housing 52 and the second housing 53.

[0098] Specifically, the fastener 523 uses bolts to fix the control board 51 by screwing, so as to avoid the control board 51 shaking inside the housing during vehicle operation and causing bumps or abnormal noises, which helps to ensure the installation quality and working stability of the control board 51.

[0099] As a feasible approach, such as Figure 11 As shown, a connecting piece 524 protrudes from the first housing 52 for fixing the first housing 52 to the seat body 100. Alternatively, the first housing 52 and the seat body 100 can be detachably connected by means of, for example, screws, to facilitate subsequent maintenance and repair, or they can be non-detachably connected by means of adhesive to improve structural stability.

[0100] As a feasible approach, combining Figure 1 and Figure 9 The aforementioned lamp board 11, lamp control board 331 and control board 51 are all connected by wiring harness 60 to realize communication and function control. One end of wiring harness 60 is provided with connector 61 to realize electrical and communication connection between wiring harness 60 and vehicle.

[0101] like Figure 12 As shown, the present invention also proposes a vehicle seat table adjustment method, applied to the aforementioned vehicle seat table adjustment device, comprising at least one of the following steps: When the tabletop 101 is opened: Press the adjustment switch 31, the transmission component 32 moves along the unlocking direction and / or locking direction of the locking part 20, thereby unlocking the locking part 20. The transmission component 32 then contacts the lighting control component 33, which controls the lighting part 10 to turn on. Tabletop 101 storage: Based on the external force that causes the tabletop 101 to be stored, the tabletop 101 applies force to the locking part 20, causing the locking part 20 to move along its unlocking direction and / or locking direction, driving the transmission component 32 to move. The transmission component 32 contacts the lighting control component 33, and the lighting control component 33 controls the lighting part 10 to turn off.

[0102] In one embodiment, the vehicle seat table adjustment method proposed in this invention may optionally include the following steps: Lighting unit 10 adjustment: The lighting unit 10 can be controlled by the vehicle's main control system to adjust one or more of the following: on / off, brightness, and color.

[0103] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
