Description

Technical Field

[0001] This application relates to the field of automotive parts technology, specifically to a button connection mechanism, a central control screen assembly, and an automobile. Background Technology

[0002] With the rapid development of the automotive industry, the configuration of car cabins is constantly being optimized and upgraded to meet the usage habits and needs of different users. Among these, the design of the display screen is particularly crucial. To better adapt to the operational needs of drivers and passengers in different scenarios, car cabin displays are generally designed to be rotatable. This design not only improves the convenience of users when using the vehicle's infotainment system but also enhances the technological feel and interactivity of the cabin. For example, while driving, the driver can rotate the display screen to the optimal viewing angle for easy viewing of navigation information or vehicle driving data; while when parking and resting or using in-car entertainment functions, passengers can also adjust the angle of the display screen according to their needs for a more comfortable visual experience.

[0003] Traditionally, extended buttons for the driver's side of a car cockpit are connected using either magnetic attachment or by drilling holes in the corresponding position of the driver's side display screen. Since the extended buttons are usually elongated to fit the screen, the magnetic connection between the extended buttons and the screen is not tight enough. At the same time, drilling holes in the corresponding position of the display screen increases the production cost of the display screen. Utility Model Content

[0004] One objective of this application is to provide a button connection mechanism to solve the problem that in the prior art, expansion buttons are usually connected by magnetic attraction or by opening holes in the corresponding position of the driver's display screen, resulting in insufficient connection between the expansion buttons and the screen, and that opening holes in the corresponding position of the display screen increases the production cost of the display screen; the second objective is to provide a central control screen assembly; and the third objective is to provide a vehicle.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A button connection mechanism, comprising:

[0007] The carrier plate has a back plate support section and a frame support section. The back plate support section and the frame support section are connected and set at an angle. The back plate support section and the frame support section enclose a support space, which is used to accommodate part of the structure of the limiting display screen.

[0008] A button assembly, comprising a housing and a button, wherein the button and the housing are rotatably connected, and the housing is connected to the back plate support section and abuts against the frame support section.

[0009] Based on the aforementioned technical means, by setting a carrier plate on the button assembly, the housing is directly connected to the carrier plate, and then the display screen is installed using the bearing space inside the carrier plate, thus avoiding the problem of drilling holes in the display screen's housing. The stable connection between the carrier plate and the housing ensures a stable connection between the button assembly and the display screen, thereby solving the problem that in the prior art, expansion buttons usually use magnetic attraction or drilling holes in the corresponding positions of the driver's side display screen for connection, resulting in insufficient tightness between the expansion buttons and the screen, and increasing the production cost of the display screen by drilling holes in the corresponding positions of the display screen.

[0010] Furthermore, the housing has a connecting portion protruding at one end near the back plate bearing section, and a connecting groove is formed at one end of the back plate bearing section near the housing, with the connecting portion accommodating and confined within the connecting groove.

[0011] Based on the above technical means, the connection between the housing and the back plate support section through the connecting part and the connecting groove ensures the stability of the installation of both the carrier plate and the button assembly.

[0012] Furthermore, the housing has a snap-fit ​​portion protruding at one end near the back plate bearing section, and the back plate bearing section has a snap-fit ​​mating portion at one end near the housing, and the snap-fit ​​portion snaps into the snap-fit ​​mating portion.

[0013] Based on the above technical means, the snap-fit ​​part and the snap-fit ​​mating part not only ensure the reliability of the connection between the housing and the carrier plate, but also facilitate the user to disassemble the button assembly or the housing separately.

[0014] Furthermore, a limiting boss is provided on the side of the connecting part facing the bottom of the connecting groove, and a limiting groove is provided on the bottom of the connecting groove, and the limiting boss is accommodated and limited in the limiting groove.

[0015] According to the above technical means, by cooperating with the limiting boss on the connecting part and the limiting groove of the connecting groove, the rotation between the carrier plate and the housing is prevented during the rotation of the display screen, which would lead to the failure of the connection between the two.

[0016] Furthermore, the housing includes a plurality of connecting portions and a plurality of snap-fit ​​portions, and a plurality of flattening portions protrude from one end of the housing near the carrier plate, wherein the two ends of a flattening portion are connected to the housing and a connecting portion; and / or, the two ends of a flattening portion are connected to the housing and a snap-fit ​​portion.

[0017] Based on the above technical means, the setting of the flat part can ensure that there is a certain buffer space between the carrier plate and the shell. The display screen can dissipate heat through this buffer space or be cushioned in the event of a collision. At the same time, the tilt angle of the display screen can be adjusted to give users a better viewing experience.

[0018] Furthermore, the housing has two contracting sections near both ends and a main body section in the middle, with both ends of the main body section connected to the two contracting sections respectively.

[0019] Based on the aforementioned technical means, the shrinking structure design at both ends of the housing can prevent users from colliding with the structure at both ends of the housing when using the display screen and button connection mechanism, further optimizing the space inside the cockpit.

[0020] Furthermore, the button connection mechanism also includes a knob, and the main body section has a protruding support portion, on which the knob is rotatably mounted.

[0021] Based on the above technical means, the setting of the support part can effectively prevent the knob from failing during rotation. The support part supports the knob, effectively improving the service life of the knob. Under long-term force, the knob is not easily deformed or twisted.

[0022] Furthermore, the vertical projection of the button gradually decreases along the direction from near the housing to far away from the housing.

[0023] Based on the above technical means, the end of the button that is wider near the housing has high reliability; the end that the user's finger touches the button is narrower, which increases the distance between two adjacent buttons touched by the finger and reduces the accidental touch rate.

[0024] Furthermore, a limiting groove is formed at the end of the button near the carrier plate, and the limiting groove is located at the end of the button near the housing.

[0025] Based on the aforementioned technical means, the limiting groove on the button can be used to reduce weight, and can also provide a place to paste stickers for the button's purpose.

[0026] A central control screen assembly includes the aforementioned button connection mechanism.

[0027] Based on the above technical means, by setting the button connection mechanism, a stable connection can be achieved between the button assembly and the carrier board, and then a stable connection between the button assembly and the display screen can be achieved through the cooperation between the display screen and the carrier board.

[0028] A car that includes the aforementioned central control screen assembly.

[0029] Based on the aforementioned technical means, this central control screen assembly is installed in the car's cockpit, particularly in the center console or dashboard area. The carrier plate within the central control screen assembly is connected to the car's interior structure via screws or other fixing methods, ensuring its stability during vehicle operation. Through this design, the central control screen assembly is seamlessly integrated with other car components, providing users with an efficient and convenient operating interface.

[0030] The beneficial effects of this application are:

[0031] (1) In this application, the back plate support section and the frame support section of the carrier board form an angle and enclose a support space. This support space can accommodate part of the display screen structure, such as the rear frame or edge part of the display screen. The housing of the button assembly is fixedly connected to the back plate support section of the carrier board by screws, clips or other mechanical connection methods, and the edge of the housing is tightly abutted against the frame support section, thereby forming a stable support structure.

[0032] (2) By mounting the display screen through the carrier plate's support space, opening holes in the display screen housing is avoided, thereby reducing the production cost of the display screen and improving its overall aesthetics and sealing. The stable connection between the carrier plate and the housing ensures a tight fit between the button assembly and the display screen, solving the problem of loose magnetic connections in existing technologies and improving the lifespan and operational reliability of the buttons. In practical applications, this connection method can effectively prevent the buttons from loosening or falling off during vehicle travel due to bumps or vibrations. Attached Figure Description

[0045] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0046] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0047] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0048] In order to solve the problems that in the prior art, the expansion button 22 is usually connected by magnetic attraction or by opening a hole at the corresponding position of the driver's side display screen 4, the connection between the expansion button 22 and the screen is not tight enough, and the opening a hole at the corresponding position of the display screen 4 increases the production cost of the display screen 4, this application provides a button connection mechanism that can achieve a stable connection between the button assembly 2 and the display screen 4 through the connection between the housing 21 and the carrier plate 1, and the support of the display screen 4 by the carrier plate 1 bearing space 13.

[0049] Please see Figures 1 to 7 This application provides a button connection mechanism, including a carrier plate 1 and a button assembly 2. The carrier plate 1 has a back plate support section 11 and a frame support section 12. The back plate support section 11 and the frame support section 12 are connected and set at an angle. The back plate support section 11 and the frame support section 12 enclose a support space 13, which is used to accommodate part of the structure of the limiting display screen 4. The button assembly 2 includes a housing 21 and a button 22. The button 22 and the housing 21 are rotatably connected. The housing 21 is connected to the back plate support section 11 and abuts against the frame support section 12.

[0050] In this embodiment, the carrier plate 1 serves as the core component for connection. Its back plate support section 11 and frame support section 12 form an angle, enclosing a support space 13. This support space 13 can accommodate part of the structure of the display screen 4, such as the rear frame or edge portion of the display screen 4. The housing 21 of the button assembly 2 is fixedly connected to the back plate support section 11 of the carrier plate 1 by screws, clips, or other mechanical connections, and the edge of the housing 21 abuts tightly against the frame support section 12, thereby forming a stable support structure. The button 22 itself is rotatably connected to the housing 21, for example, by using a pivot or hinge structure, allowing the button 22 to be adjusted in angle according to the user's operating needs. The carrier plate 1 can be designed as a plastic material to reduce weight and cost. Multiple threaded holes are provided on the back plate support section 11 for screw-fixed connection with the housing 21. The frame support section 12 supports and abuts against the frame of the display screen 4. The included angle α between the back plate support section 11 and the frame support section 12 is generally 90°. This design ensures the stability of the entire carrier plate 1 structure. A wrapping structure can be provided on the side of the back plate support section 11 and the frame support section 12 closest to the display screen 4 to facilitate better fit between the carrier plate 1 and the display screen 4. The housing 21 of the button assembly 2 can be designed as a metal material to enhance structural strength. Users can operate functions such as volume adjustment, air conditioning control, or window opening / closing by toggling the buttons 22.

[0051] It should be noted that in this application, the display screen 4 is mounted through the support space 13 of the carrier plate 1, avoiding the need for opening holes in the casing of the display screen 4, thereby reducing the production cost of the display screen 4 and improving its overall aesthetics and sealing performance. The stable connection between the carrier plate 1 and the casing 21 ensures a tight fit between the button assembly 2 and the display screen 4, solving the problem of loose magnetic connections in the prior art and improving the service life and operational reliability of the buttons 22. In practical applications, this connection method can effectively prevent the buttons 22 from loosening or falling off during vehicle travel due to bumps or vibrations.

[0052] Please see Figure 3 , Figure 4 and Figure 6 The housing 21 has a connecting part 211 protruding at one end near the back plate support section 11, and a connecting groove 111 is opened at one end of the back plate support section 11 near the housing 21. The connecting part 211 is accommodated and limited in the connecting groove 111. The connection between the housing 21 and the back plate support section 11 through the connecting part 211 and the connecting groove 111 ensures the stability of the installation of both the carrier plate 1 and the button assembly 2.

[0053] In one embodiment of this application, a connecting portion 211 protrudes from one end of the housing 21 near the backplate support section 11. This connecting portion 211 can be designed as one or more protrusions or bumps, and its shape can be rectangular, circular, or other suitable geometric shapes. A connecting groove 111 matching the connecting portion 211 is formed at one end of the backplate support section 11 near the housing 21. The shape and size of the connecting groove 111 are adapted to the connecting portion 211 to ensure that the connecting portion 211 can be tightly accommodated and confined within the connecting groove 111. Through this cooperation between the connecting portion 211 and the connecting groove 111, a stable mechanical connection is formed between the housing 21 and the backplate support section 11. For example, the connecting portion 211 can be designed as two symmetrical rectangular protrusions, and the connecting groove 111 can be two corresponding rectangular slots. By inserting the protrusions into the slots and further securing them with clips or screws, the connection strength between the housing 21 and the backplate support section 11 can be ensured. This connection method not only ensures stable installation between the button assembly 2 and the carrier plate 1 but also facilitates disassembly and maintenance.

[0054] This structural design avoids the loosening or detachment problems that can occur with traditional connection methods, especially under the bumps and vibrations of vehicle operation, effectively maintaining the stability and reliability of the button assembly 2. During vehicle operation, when the user frequently operates button 22, this stable connection prevents button assembly 2 from shifting or loosening due to vibration, thereby improving the user experience. Furthermore, this connection method facilitates the installation and removal of button assembly 2, reducing production costs and maintenance difficulty. Through this design, this application not only improves product quality and lifespan but also enhances user satisfaction and the product's market competitiveness.

[0055] Please see Figure 3 , Figure 4 and Figure 6 The housing 21 has a protruding snap-fit ​​portion 212 at one end near the back plate support section 11, and a snap-fit ​​mating portion 112 is provided at the other end of the back plate support section 11 near the housing 21. The snap-fit ​​portion 212 snaps into the snap-fit ​​mating portion 112. The snap-fit ​​portion 212 snaps into the snap-fit ​​mating portion 112, which ensures the reliability of the connection between the housing 21 and the carrier plate 1, and also facilitates the user to disassemble the button assembly 2 or the housing 21 separately.

[0056] In this embodiment, a snap-fit ​​portion 212 protrudes from one end of the housing 21 near the back plate support section 11. This snap-fit ​​portion 212 can be designed as a resilient buckle, hook, or other suitable snap-fit ​​structure. A snap-fit ​​mating portion 112, such as a slot or hole, is provided at one end of the back plate support section 11 near the housing 21 to match the snap-fit ​​portion 212. By inserting the snap-fit ​​portion 212 into the snap-fit ​​mating portion 112 and locking it in place, a stable mechanical connection is formed between the housing 21 and the back plate support section 11. This snap-fit ​​structure not only ensures the reliability of the connection but also facilitates the user's individual disassembly of the button assembly 2 or the housing 21.

[0057] Please see Figures 4 to 6 A limiting boss 213 protrudes from the side of the connecting part 211 facing the bottom of the connecting groove 111, and a limiting groove 113 is formed at the bottom of the connecting groove 111. The limiting boss 213 is accommodated and limited in the limiting groove 113. By cooperating with the limiting boss 213 on the connecting part 211 and the limiting groove 113 of the connecting groove 111, rotation between the carrier plate 1 and the housing 21 is prevented during the rotation of the display screen 4, which would lead to the failure of the connection between the two.

[0058] In one embodiment of this application, a limiting boss 213 protrudes from the side of the connecting portion 211 facing the bottom of the connecting groove 111, while a limiting groove 113 is formed at the bottom of the connecting groove 111. The shapes and sizes of the limiting boss 213 and the limiting groove 113 are matched, allowing the limiting boss 213 to be tightly accommodated and confined within the limiting groove 113. This design effectively prevents relative rotation between the carrier plate 1 and the housing 21 during the rotation of the display screen 4, thereby avoiding connection failure between the two. For example, the limiting boss 213 can be designed as a circular or rectangular protrusion, and the limiting groove 113 as a corresponding circular or rectangular groove. By inserting the limiting boss 213 into the limiting groove 113 and ensuring a tight fit, a stable limiting effect can be achieved. In another embodiment, the limiting boss 213 can be designed as multiple small protrusions, and the limiting groove 113 as multiple corresponding small recesses, further enhancing stability through multi-point limiting. This limiting structure not only improves the reliability of the connection, but also ensures a stable connection between the button assembly 2 and the carrier plate 1 under various operating conditions.

[0059] This limiting structure effectively prevents relative rotation between the carrier plate 1 and the housing 21, thereby avoiding connection failure due to rotation and improving product reliability and service life. For example, during vehicle operation, the display screen 4 may rotate due to user operation; this limiting structure ensures that the connection between the button assembly 2 and the carrier plate 1 remains stable and will not loosen or detach due to rotation. Furthermore, this design improves the overall performance and user experience of the product, allowing users to use the button assembly 2 with greater confidence. Through this limiting structure, this application not only improves product quality and reliability but also enhances user satisfaction and the product's market competitiveness.

[0060] Please see Figures 4 to 6 The housing 21 includes multiple connecting portions 211 and multiple snap-fit ​​portions 212. Multiple flattening portions 214 protrude from one end of the housing 21 near the carrier plate 1. The two ends of one flattening portion 214 connect the housing 21 and a connecting portion 211; and / or, the two ends of one flattening portion 214 connect the housing 21 and a snap-fit ​​portion 212. The flattening portions 214 ensure a certain buffer space between the carrier plate 1 and the housing 21, allowing the display screen 4 to dissipate heat or cushion impacts. Simultaneously, the tilt angle of the display screen 4 can be adjusted, providing a better viewing experience for the user.

[0061] In one embodiment, the housing 21 is designed with multiple connecting portions 211 and multiple snap-fit ​​portions 212 to enhance the connection stability with the carrier plate 1. Multiple flattening portions 214 protrude from one end of the housing 21 near the carrier plate 1, with each end of these flattening portions 214 connecting the housing 21 to either the connecting portion 211 or the snap-fit ​​portion 212. The flattening portions 214 can be designed as a material with a certain degree of elasticity, such as rubber or silicone, to provide cushioning. The housing 21 can be designed as a metal material to enhance structural strength, while the flattening portions 214 are made of rubber to provide good cushioning performance. Each flattening portion 214 is mechanically connected to the housing 21 and either the connecting portion 211 or the snap-fit ​​portion 212 via a mechanical connection (such as screws or clips). This design not only ensures a certain buffer space between the carrier plate 1 and the housing 21, but also allows the display screen 4 to dissipate heat through this buffer space. The leveling part 214 can be designed as an adjustable structure, for example, by means of a threaded adjustment device, so that the user can adjust the tilt angle of the display screen 4 according to their own needs, thereby obtaining a better user experience.

[0062] Please see Figure 4 The housing 21 has two retractable sections 215 near both ends and a main body section 216 in the middle, with both ends of the main body section 216 connected to the two retractable sections 215 respectively. The retractable structure design at both ends of the housing 21 can prevent the user from colliding with the structure at both ends of the housing 21 when using the display screen 4 and the button connection mechanism, further optimizing the space inside the cockpit.

[0063] In this embodiment, the housing 21 is designed with two tapering sections 215 near both ends and a central main body section 216, with both ends of the main body section 216 connected to the two tapering sections 215 respectively. This structural design causes the housing 21 to gradually narrow at both ends, thus forming the tapering sections 215. The housing 21 can be manufactured using a one-piece molding process, with the main body section 216 having a rectangular or trapezoidal structure, and the tapering sections 215 at both ends transitioning to narrower ends through gradually decreasing slopes or arc surfaces. This design can be achieved through injection molding, using high-strength plastic materials to ensure the structural strength of the housing 21. This tapering structure not only optimizes the spatial layout within the cockpit but also improves the safety and comfort of the user when using the display screen 4 and the button connection mechanism.

[0064] This application significantly improves the space utilization efficiency and user safety within the cockpit by designing retractable sections 215 at both ends of the housing 21. The retractable sections 215 prevent users from colliding with the structures at both ends of the housing 21 when using the display screen 4 and the button connection mechanism, thereby reducing the risk of injury due to collisions. For example, during vehicle operation, a user's fingers or arms may accidentally touch both ends of the housing 21; the smooth transition of the retractable sections 215 effectively avoids injury from sharp edges. Furthermore, this design optimizes the spatial layout within the cockpit, making the display screen 4 and button connection mechanism more compact and improving the overall aesthetics and tidiness of the cockpit. Through this design, this application not only improves product safety and user experience but also enhances the product's market competitiveness.

[0065] Please see Figures 1 to 4 The button connection mechanism also includes a knob 3. The main body section 216 has a protruding support part 217, and the knob 3 is rotatably mounted on the support part 217. The support part 217 can effectively prevent the knob 3 from failing during rotation. The support part 217 supports the knob 3, effectively improving the service life of the knob 3. Under long-term force, the knob is not easily deformed or bent.

[0066] It should be noted that a support portion 217 protrudes from the main body section 216. The knob 3 is mounted on the support portion 217 via a bearing or other rotating device, thereby enabling the knob 3 to rotate freely. The support portion 217 can be designed in various structural forms. For example, a raised circular platform can be provided on the main body section 216, with a hole in the center of the platform for mounting the rotating shaft of the knob 3. The rotating shaft of the knob 3 is connected to the support portion 217 via a bearing, ensuring that the knob 3 rotates smoothly and without jamming. For example, the support portion 217 can be designed as a circular platform made of metal, with a high-precision ball bearing installed in the hole in the center of the platform to reduce friction and improve the smoothness of rotation.

[0067] By installing the knob 3 with a support portion 217 on the main body section 216, the service life and operational reliability of the knob 3 are significantly improved. The support portion 217 effectively supports the knob 3, preventing it from deforming or warping due to external forces during long-term use, thus avoiding the problem of knob 3 failing to rotate. For example, during vehicle operation, users may frequently operate the knob 3; the design of the support portion 217 ensures that the knob 3 remains stable under long-term force, without loosening or jamming. In addition, this design also improves the durability of the knob 3, reduces the frequency of maintenance and replacement, and lowers operating costs.

[0068] Please see Figure 4The vertical projection of button 22 gradually decreases in size from near to far from housing 21. The end of button 22 near housing 21 is wider, resulting in higher reliability; the end where the user's finger contacts button 22 is narrower, increasing the distance between adjacent buttons 22 and reducing the rate of accidental touches.

[0069] In this embodiment, the button 22 is designed with a unique trapezoidal or wedge-shaped structure, so that the vertical projection of the button 22 gradually decreases from near the housing 21 to away from the housing 21. Specifically, the end of the button 22 near the housing 21 is designed to be wider, while the end that the user's finger contacts is narrower. This structure can be achieved by injection molding using high-strength plastic material to ensure the structural strength of the button 22. For example, the button 22 can be designed as a trapezoidal column with a width of 15 mm at the end near the housing 21 and a width of 10 mm at the end away from the housing 21. This design not only enhances the reliability of the end of the button 22 near the housing 21, but also increases the spacing between adjacent buttons 22 by reducing the width of the end that the user's finger contacts.

[0070] It should be noted that this application significantly improves the reliability and user experience of the button 22 by designing its vertical projection to gradually decrease in size from near to far from the housing 21. The wider end of the button 22 near the housing 21 provides stronger structural strength and connection reliability, reducing damage caused by external forces. Simultaneously, the narrower end where the user's finger contacts increases the distance between adjacent buttons 22, effectively reducing the rate of accidental touches. For example, during driving, users may need to operate the button 22 quickly and accurately; this design reduces operational errors caused by accidental touches, improving driving safety.

[0071] Please see Figure 4 and Figure 5 A limiting groove 221 is provided at the end of button 22 near the carrier plate 1. The limiting groove 221 is located at the end of button 22 near the housing 21. The limiting groove 221 on button 22 can be used to reduce weight, and can also provide a place to stick stickers for the purpose of button 22.

[0072] In one embodiment of this application, the limiting groove 221 can be designed in various shapes and sizes to meet different functional requirements. For example, the limiting groove 221 can be designed as a rectangle, a circle, or an ellipse, and its depth and width can be adjusted according to actual needs. The limiting groove 221 can be designed as a rectangle or a circle, located in the middle of the end of the button 22 near the housing 21. This design not only reduces weight and the overall weight of the button 22, but also provides a flat and stable adhesive position for subsequent application of stickers for the button 22. Through this design, the limiting groove 221 not only optimizes the structure of the button 22, but also increases the versatility of the button 22.

[0073] Please see Figures 1 to 7 This application also proposes a central control screen assembly, including the aforementioned button connection mechanism.

[0074] In this embodiment, the central control screen assembly includes the aforementioned button connection mechanism and a locking handle. The locking handle design makes the installation and removal of the display screen more convenient and secure. Specifically, one end of the locking handle is rotatably connected to the back plate support section of the carrier plate via a pivot, allowing the handle to rotate within a certain angle. The other end is designed with a detachable connection structure, such as a clip or screw, for fixed connection with the back plate support section. When the locking handle is connected to the back plate support section, they together form a connection channel whose shape and size match the connection part of the display screen for secure connection of the display screen.

[0075] Please see Figures 1 to 7 This application also proposes a car that includes the aforementioned central control screen assembly.

[0076] Specifically, this central control screen assembly is installed in the car's cockpit, particularly in the center console or dashboard area. The carrier plate 1 within the central control screen assembly is connected to the car's interior structure via screws or other fixing methods, ensuring its stability during vehicle operation. Components such as the button assembly 2 and knobs 3 are rationally arranged according to the cockpit layout and user operating habits. For example, the central control screen assembly can be installed on the center console for convenient operation by the driver and front passenger. Knobs 3 can be located on one side of the display screen 4 for adjusting volume, switching menus, and other functions. Through this design, the central control screen assembly seamlessly integrates with other car components, providing users with an efficient and convenient operating interface. Installing the display screen 4 through the carrying space 13 of the carrier plate 1 avoids drilling holes in the display screen 4's housing, thereby reducing the production cost of the display screen 4 while improving its overall aesthetics and sealing. The stable connection between the carrier plate 1 and the housing 21 ensures a tight fit between the button assembly 2 and the display screen 4, solving the problem of loose magnetic connections in existing technologies and improving the lifespan and operational reliability of the buttons 22. In practical applications, this connection method can effectively prevent the button 22 from becoming loose or falling off during vehicle travel due to bumps or vibrations.
