Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an in-vehicle control device. Background Technology

[0002] In today's era of rapid advancements in automotive technology, the methods of controlling vehicle functions are also constantly evolving. With the increasing trend towards intelligence and connectivity, more and more in-vehicle products are adopting full-touch control methods to operate various vehicle functions, aiming to provide users with a more convenient and technologically advanced interactive experience. This full-touch control method integrates the functions of previously scattered physical buttons into a touchscreen or touch panel. Users can control numerous vehicle functions, such as adjusting the air conditioning temperature, switching multimedia playback content, and adjusting seat positions, simply by touching virtual buttons and icons on the screen or performing specific gestures.

[0003] However, the full-touch control method has gradually revealed some problems in actual use. When the vehicle is traveling on bumpy roads, the user's hand becomes difficult to operate the touch screen steadily due to vehicle vibration, leading to frequent accidental touches and significantly affecting the accuracy and safety of operation. For example, while driving, the driver may intend to adjust the volume but accidentally touch other function options due to the bumps, interfering with normal driving. In some emergency situations, such as when the vehicle needs to brake suddenly, the driver may panic and be unable to quickly and accurately find the corresponding operation option on the touch screen, delaying the best operating time and posing a potential risk to driving safety. In addition, for some users with poor eyesight or unfamiliar with full-touch operation, the full-touch control method is more difficult to operate. They cannot accurately complete the required functions without looking at the screen, and cannot achieve blind operation, which to some extent limits the user's convenient use of vehicle functions.

[0004] Meanwhile, features such as vehicle seats, leg rests, tailgate, sunroof curtains, window curtains, and interior lighting are crucial for user comfort and convenience during driving. Adjustable seats allow users to find the most comfortable seating position, alleviating fatigue from long drives or rides; leg rests provide more comfortable leg support for long journeys; easy opening and closing of the tailgate facilitates loading and unloading; sunroof curtains and window curtains control the amount of light and privacy inside the vehicle; and proper control of interior lighting creates a comfortable atmosphere. However, existing all-touch control methods do not provide an efficient, reliable, and convenient solution for operating these functions, leaving users facing numerous inconveniences and frustrations.

[0034] Please refer to Figures 1 to 7 As shown, an embodiment of this application provides a vehicle control device 100, which includes a housing 10, a button assembly 20, and a control board 30. The housing 10 has an internal receiving space. The button assembly 20 is mounted on the housing 10 and protrudes from the housing 10. The control board 30 is disposed within the receiving space and includes a PCB board 31 and multiple button switch groups 32. The button switch groups 32 are corresponding to the button assembly 20, and pressing the button assembly 20 triggers the button switch groups 32. The housing 10 is used to install within a cavity 200 below the air conditioning vent of a vehicle. The housing 10 includes a main housing 11 and two curved panels 12 mounted at both ends of the main housing 11. The two curved panels 12 are respectively used to conform to the two side walls of the cavity 200.

[0035] Specifically, the housing 10 serves as the basic supporting component of the device, forming an independent internal space to provide an installation carrier for core components such as the control board 30. The housing 10 consists of a main housing 11 and two curved panels 12, which are respectively mounted at both ends of the main housing 11 along its length. The curved panels 12 adopt an arc-shaped design adapted to the curvature of the side wall of the cavity 200 below the automotive air conditioning vent, providing good structural adaptability. The button assembly 20 adopts a modular design, installed on the outer surface of the housing 10 with some structures exposed outside the housing 10, forming a directly operable physical button structure capable of pressing and flicking trigger functions, corresponding to multiple function control requirements such as vehicle seats, leg rests, and tailgates. The control board 30 is integrated within the housing 10's internal space. Its core components include a PCB board and multiple button switch groups 32. The button switch groups 32 and the button assembly 20 form a one-to-one positional relationship, achieving signal transmission through circuit connections, and possessing stable electrical signal trigger response capabilities.

[0036] The control board 30 is internally mounted within the housing 10, with its PCB board fixedly connected to the housing 10 to ensure structural stability. The button assembly 20 is embedded in the housing 10, with its trigger end precisely aligned with the button switch group 32 on the control board 30, forming a mechanical trigger structure. When the button assembly 20 is pressed, it directly acts on the corresponding button switch group 32. The curved panel 12 of the housing 10 provides the overall mounting and positioning function for the device, and is fixed by fitting against the side wall of the cavity 200. The button assembly 20 serves as the human-machine interface, receiving user pressing and toggling operations and transmitting them to the button switch group 32. The control board 30, triggered by the signals from the button switch group 32, converts mechanical operations into electrical signal commands, thereby outputting control signals for vehicle functions. The overall size of the housing 10 matches the cavity 200 below the car air conditioning vent. The fitting structure between the curved panel 12 and the side wall of the cavity 200 eliminates the installation gap, making the device an integrated layout with the vehicle interior. The height of the button assembly 20 exposed from the housing 10 and the angle of the operating surface are adapted to the human hand operation habits.

[0037] This application employs a housing 10 structure combining a main shell 11 and a curved panel 12, which precisely adapts to the installation environment of the cavity 200 below the car's air conditioning vents. The design of the curved panel 12 fitting snugly against the side wall ensures a stable installation, preventing shaking or abnormal noise during vehicle operation, while maintaining the integrity and aesthetics of the interior. The physical button assembly 20 protrudes from the housing 10, allowing users to operate blindly through touch, controlling functions without looking at the interface. This effectively solves the problem of accidental touches on bumpy roads caused by full-touch operation, improving operational safety and accuracy during driving. The corresponding design of the button assembly 20 and the button switch group 32 enables centralized control of multiple functions such as seats and lights, replacing scattered touch operation paths, reducing user operation steps, and improving the response efficiency of function control.

[0038] In this embodiment, the curved panel 12 is fixed to the two side walls of the cavity 200 below the car's air vents using an adhesive bonding design, which can precisely adapt to the installation environment of the cavity 200 below the car's air conditioning vents. The adhesive bonding method not only achieves a tight fit between the curved panel 12 and the side walls, but also absorbs minor vibrations during vehicle operation through the buffering effect of the adhesive layer, preventing the device from shaking or making abnormal noises. It also maintains the integrity and aesthetics of the car's interior, and the installation process requires no additional drilling or damage to the original car interior structure, reducing damage to the vehicle.

[0039] Furthermore, the button assembly 20 includes multiple control buttons 21, the number of which is the same as the number of button switch groups 32, and each button switch group 32 corresponds one-to-one with a control button 21. The button assembly 20 is used to control at least the following functions: moving the vehicle's seat forward and backward, raising and lowering the seat leg rest, opening and closing the tailgate, opening and closing the sunroof curtain, opening and closing the window curtains, turning the interior lights on and off, and adjusting the interior light brightness.

[0040] In this embodiment, both the control buttons 21 and the button switch group 32 are multiple, and the number of both is the same. The control buttons 21 and the button switch group 32 are consistent in number, forming a strict one-to-one correspondence. At the same time, the control function range of the button assembly 20 is refined, specifically covering seven core functions: vehicle seat forward and backward adjustment, seat leg rest raising and lowering adjustment, tailgate opening and closing operation, sunroof curtain opening and closing operation, window curtain opening and closing operation, interior light on and off control, and interior light brightness adjustment. Each control button 21 corresponds to the trigger command of one of these functions.

[0041] The one-to-one correspondence between the control buttons 21 and the push-button switch group 32 is not only a precise alignment in position, but also a direct mapping in function. That is, when the user presses the button to control the seat forward, the operation will be accurately transmitted to the corresponding push-button switch group 32, and the control board 30 will then output an electrical signal command to move the seat forward; similarly, the operation of the leg rest, tailgate, various curtains and lights is achieved through the cooperation of the corresponding control buttons 21 and push-button switch group 32 to achieve accurate transmission of function commands.

[0042] The one-to-one correspondence between control buttons 21 and specific functions allows functions such as seat adjustment and curtain control, which previously required multi-level touch menus, to be triggered directly by buttons, further reducing the number of operation steps. For frequently used functions such as turning interior lights on and off and adjusting brightness, the independent button design allows users to quickly switch and adjust while driving, significantly improving the convenience and responsiveness of function control. In terms of operational convenience, the independent button design for these specific functions enhances the accuracy of users' tactile identification of different function buttons, making blind operation more efficient and reliable for controlling frequently used functions.

[0043] Furthermore, the vehicle control device 100 also includes an indicator panel 40, which has indicator icons that correspond one-to-one with the control buttons 21.

[0044] Specifically, the indicator panel 40 is an important component of the vehicle control device 100. Its surface is equipped with clear indicator icons, and the number and position of the indicator icons maintain a strict one-to-one correspondence with the control buttons 21. Each indicator icon adopts an intuitive and easy-to-understand graphic or symbol design, corresponding to various control functions such as seat forward and backward movement, seat leg rest raising and lowering, tailgate opening and closing, sunroof curtain opening and closing, window curtain opening and closing, interior lights turning on and off, and interior light brightness, enabling users to quickly identify the function of each control button 21.

[0045] The indicator panel 40 is fixedly connected to the housing 10 and is installed close to the control button 21, ensuring that the indicator icon and the corresponding control button 21 are precisely aligned in space. When observing the indicator panel 40, the user can clearly associate the icon with the control button 21 below or next to it. In the functional collaboration, the indicator panel 40 serves as a function identification carrier, providing visual guidance to the user and helping the user quickly match the control button 21 with the corresponding function. Together with the control button 21 and the button switch group 32, it forms a complete human-computer interaction system. The user identifies the function through the indicator panel 40, then operates the corresponding control button 21, which in turn triggers the button switch group 32 to achieve function control.

[0046] The indicator panel 40 solves the problem of unfamiliar button functions for users, especially first-time users. They don't need to memorize the function of each control button 21; the intuitive indicator icons allow them to quickly understand the button's purpose, shortening the user's adaptation time. In driving scenarios, users can quickly locate the required control button 21 using the indicator icons, reducing the time their eyes spend on the device and further improving driving safety. Simultaneously, the one-to-one correspondence between the indicator icons and control buttons 21 avoids misoperation due to button confusion, improving the accuracy of function control. Especially in low-light environments, if the indicator icons are luminous, users can still clearly identify the button functions even in low-light conditions.

[0047] Furthermore, the main shell 11 includes a bottom shell 111 and a cover plate 112. The cover plate 112 is placed on the bottom shell 111 to form an accommodating space. The inner wall of the bottom shell 111 protrudes a plurality of first positioning posts 1111 towards the cover plate 112, and the cover plate 112 protrudes a plurality of second positioning posts 1121 towards the first positioning posts 1111. The PCB board 31 is sandwiched between the first positioning posts 1111 and the second positioning posts 1121.

[0048] Specifically, in this embodiment, the main shell 11 consists of a bottom shell 111 and a cover plate 112. The cover plate 112 is fitted onto the bottom shell 111 in a covering manner, and the two together enclose a closed receiving space for accommodating the control board 30. A plurality of first positioning posts 1111 are integrally formed protruding from the inner wall of the bottom shell 111 towards the cover plate 112. A plurality of second positioning posts 1121 are protruding from the side of the cover plate 112 facing the bottom shell 111, corresponding to the positions of the first positioning posts 1111. The first positioning posts 1111 and the second positioning posts 1121 correspond one-to-one in number and position. The PCB board is precisely clamped between the first positioning posts 1111 and the second positioning posts 1121, and is fixed through the combined action of the two.

[0049] The bottom shell 111 and the cover plate 112 are connected to form the overall structure of the main shell 11, with their connecting edges tightly fitting together to ensure the sealing of the accommodating space. The first positioning post 1111 and the second positioning post 1121 form an opposing clamping structure. When the cover plate 112 is placed on the bottom shell 111, the top of the first positioning post 1111 abuts against the bottom surface of the PCB board, and the top of the second positioning post 1121 abuts against the top surface of the PCB board. This clamping force firmly fixes the PCB board in a preset position, preventing displacement within the accommodating space. Simultaneously, the precise height of the positioning posts ensures an appropriate gap between the PCB board and the bottom shell 111 and cover plate 112, providing stable support without affecting the normal operation of components on the PCB board.

[0050] The separate design of the bottom shell 111 and the cover plate 112 facilitates the installation and subsequent maintenance of the control board 30. The clamping and fixing method of the first positioning post 1111 and the second positioning post 1121 for the PCB board can effectively resist the vibration and impact during vehicle operation, prevent the PCB board from shaking and causing problems such as solder joint detachment and component damage, and significantly improve the structural stability and service life of the control board 30.

[0051] In this embodiment, both the first positioning post 1111 and the second positioning post 1121 have through threaded holes at their axial centers, and the PCB board has mounting through holes adapted to the threaded holes corresponding to the clamping positions of the first positioning post 1111 and the second positioning post 1121. The device forms a threaded connection structure by passing screws through the threaded holes of the second positioning post 1121, the mounting through holes of the PCB board, and the threaded holes of the first positioning post 1111, thereby achieving rigid fixation of the PCB board. This further locks the PCB board in place by fasteners on top of the clamping of the first positioning post 1111 and the second positioning post 1121.

[0052] Furthermore, the PCB board 31 has multiple positioning grooves 311, and the cover plate 112 protrudes multiple third positioning posts 1122 into the positioning grooves 311, with each third positioning post 1122 inserted into one of the multiple positioning grooves 311.

[0053] Specifically, based on the original structure, the PCB board has multiple positioning grooves 311 on its edges or in non-component areas. The shape and size of these grooves are adapted to the positioning post structure. On the side of the cover plate 112 facing the PCB board, corresponding to the position of the positioning grooves 311, multiple third positioning posts 1122 are integrally protruded. The number and position of the third positioning posts 1122 correspond one-to-one with the positioning grooves 311, and their cross-sectional shape matches the inner contour of the positioning grooves 311, allowing them to be precisely inserted into the positioning grooves 311 to form a fitting structure. When the cover plate 112 is placed on the bottom shell 111, the third positioning posts 1122 and the positioning grooves 311 of the PCB board form a fitting and positioning engagement. The outer wall of the third positioning post 1122 is tightly fitted to the inner wall of the positioning groove 311, restricting the displacement of the PCB board in the horizontal direction (parallel to the board surface). This interlocking structure, together with the existing first positioning post 1111, second positioning post 1121, and screw fixing, forms a collaborative positioning system: the third positioning post 1122 constrains the movement of the PCB board in the horizontal direction, the first and second positioning posts 1121 clamp the PCB board in the vertical direction (perpendicular to the board surface), and the screws reinforce the vertical fixation through axial force. Together, these three elements constitute a three-dimensional positioning structure. This pre-positioning structure allows for rapid and precise placement of the PCB board during assembly, reducing alignment adjustment time and improving production efficiency.

[0054] Furthermore, the cover plate 112 is provided with multiple first through holes 1123 at the positions corresponding to the control buttons 21, and the multiple control buttons 21 are installed in the first through holes 1123 one by one. Each button switch group 32 includes two switches 321, and each control button 21 includes two spaced trigger protrusions 211; the control button 21 is rotatably disposed in the first through hole 1123, and the control button 21 is tossed in two directions to trigger the two switches 321 respectively through the two trigger protrusions 211.

[0055] Specifically, the cover plate 112 has multiple first through holes 1123 at positions corresponding to the control buttons 21. The number, shape, and size of these first through holes 1123 are adapted to the control buttons 21 in the button assembly 20. Each control button 21 is installed in the corresponding first through hole 1123 by an embedded installation method. The operating end of the control button 21 protrudes from the outside of the bottom shell 111 for easy pressing by the user, while the connecting end extends into the receiving space inside the bottom shell 111 to form a matching fit with the corresponding button switch group 32 on the control board 30.

[0056] Each push-button switch group 32 consists of two independent switches 321, which are spaced apart and positioned on the PCB board at the positions corresponding to the control buttons 21. Each control button 21 has two spaced-apart trigger protrusions 211 at its connection end. These protrusions are elongated and their height is adapted to the trigger end of the switch 321. The control button 21 is mounted in the first through hole 1123 via a rotating shaft structure. The rotating shaft is integrally formed on the wall of the first through hole 1123. The control button 21 has a corresponding shaft hole adapted to the rotating shaft. The control button 21 can be tossed around the rotating shaft in two opposite directions at a certain angle. When tossed in one direction, one trigger protrusion 211 contacts and triggers one of the switches 321 in the push-button switch group 32; when tossed in the other direction, the other trigger protrusion 211 contacts and triggers the other switch 321 in the same push-button switch group 32.

[0057] The rotating shaft on the wall of the first through hole 1123 forms a precise rotational fit with the shaft hole of the control button 21. The axis of the rotating shaft remains parallel to the operating surface of the control button 21, ensuring smooth and stable operation. The two trigger protrusions 211 correspond to the positions of the two switches 321 in the button switch group 32, forming a precise trigger alignment in space. When the control button 21 is in its initial unmoved state, neither of the two trigger protrusions 211 contacts the switch 321. When the control button 21 is moved to one side, it deflects around the rotating shaft of the hole wall, causing one of the trigger protrusions 211 to approach and apply pressure to the corresponding switch 321, triggering that switch 321. When moved in the opposite direction, the other trigger protrusion 211 triggers the other switch 321 in the same way. This structure creates a one-to-one bidirectional trigger association between a single control button 21 and two switches 321, allowing one control button 21 to control the on / off state of two switches 321 through operation in different directions.

[0058] The design employs dual switches 321 and dual trigger protrusions 211, enabling a single control button 21 to control two related functions, such as seat forward and backward movement, and curtain opening and closing. This eliminates the need for separate buttons for each function, reducing the number of control buttons 21, saving device space, and simplifying user operation logic. Users can switch between opposite functions by bidirectional tossing a single button, improving ease of use. Regarding trigger reliability, the design of the rotating shaft located on the wall of the first through hole 1123 enhances the stability and load-bearing capacity of the rotating structure, preventing the control button 21 from loosening or shifting after frequent and prolonged use, ensuring long-term stable alignment accuracy between the trigger protrusions 211 and the switches 321. The tossing operation provides clearer feedback compared to pressing, allowing users to perceive the direction and trigger status through tactile feedback, reducing the probability of misoperation. Simultaneously, the independent triggering structures of the two trigger protrusions 211 and the two switches 321 prevent interference between functions, ensuring the accuracy of each function's control. In driving scenarios, this flicking operation is more in line with human hand movement habits. Users can quickly adjust functions with a slight flick of their fingers, further improving operational safety during driving.

[0059] Furthermore, two spaced second through holes 1112 are provided on both sides of the length of the bottom shell 111, and two retaining plate walls 121 are provided at the corresponding positions of the second through holes 1112 on the curved panel 12; each retaining plate wall 121 includes a first wall 1211 and a second wall 1212, the first wall 1211 passes through the second through hole 1112, and the second wall 1212 extends into the bottom shell 111 and fits against the inner surface of the side wall; one of the second walls 1212 is provided with a latching part 1213, and a retaining groove part 1113 is provided at the position corresponding to the latching part 1213 on the inner surface of the side wall, and the latching part 1213 is engaged with the retaining groove part 1113.

[0060] Specifically, two spaced-apart second through holes 1112 are formed on the two side walls along the length of the bottom shell 111, penetrating the inner and outer surfaces of the side walls. Two retaining wall 121 integrally extend from the curved panel 12 at positions corresponding to the second through holes 1112. Each retaining wall 121 consists of a first wall 1211 and a second wall 1212 that are perpendicular to each other, forming an L-shaped structure. The dimensions of the first wall 1211 are adapted to the second through holes 1112, allowing it to extend through the second through holes to the outside of the bottom shell 111; the second wall 1212 extends into the interior of the bottom shell 111 after the first wall 1211 passes through the through holes, fitting against the inner surface of the side wall of the bottom shell 111. One of the card plate walls 121 has an outwardly protruding latching part 1213 on its second wall 1212, and an inwardly recessed latching groove part 1113 is provided on the inner surface of the side wall of the bottom shell 111 corresponding to the position of the latching part 1213. The latching part 1213 can form an interference fit latching structure with the latching groove part 1113.

[0061] The curved panel 12 and the bottom shell 111 are connected and positioned through the engagement of the retaining plate wall 121 and the second through hole 1112: when the first wall 1211 passes through the second through hole 1112, the hole wall forms a radial constraint on the first wall 1211, ensuring the precise connection position between the curved panel 12 and the bottom shell 111; the second wall 1212 fits against the inner surface of the side wall of the bottom shell 111, further restricting the displacement of the curved panel 12 in the direction perpendicular to the side wall. When the curved panel 12 is installed in place, the snap-fit ​​part 1213 elastically deforms and snaps into the snap-fit ​​part 1113, forming an axial lock. At this time, the two retaining plate walls 121 form a symmetrical fixation from the two second through holes 1112 on the two side walls of the bottom shell 111, so that the connection between the curved panel 12 and the bottom shell 111 has both circumferential positioning accuracy and axial fixing strength. In this connection structure, the first wall 1211 and the second wall 1212 of the L-shaped card plate wall 121 form a double limit from the outside and inside of the bottom shell 111, respectively, while the buckle part 1213 and the slot part 1113 provide a reliable anti-drop function.
