Description

Technical Field

[0001] This utility model relates to the field of automotive interior technology, specifically to a central control display assembly, a display screen, a mounting bracket, an instrument panel assembly, and an automobile. Background Technology

[0002] With the continuous development of technology, automobiles are gradually transforming from mechanization to intelligence, connectivity, sharing, and electrification, and are gradually becoming a mobile intelligent super terminal that integrates transportation, communication, entertainment, and office functions.

[0003] As the primary human-machine interface between people and vehicles, automotive central control displays are increasingly integrating various functions, leading to larger and heavier displays. Simultaneously, to enhance the technological feel of the car interior, more and more central control displays are adopting a floating design. To meet these requirements, adapter mounting brackets are often needed to mount the central control display on the steering column (CCB, Car Cross Beam) or inside the dashboard. However, existing adapter mounting brackets typically integrate the positioning and mounting functions of the automotive central control display, resulting in relatively complex structures, heavy weight, and large space occupancy, limiting design flexibility and hindering the arrangement of other components and the achievement of lightweight design. Utility Model Content

[0004] One objective of this utility model is to provide a central control display screen assembly to solve the problems of relatively complex structure, heavy weight, and large space occupation of the existing adapter mounting bracket; another objective is to provide a display screen; a third objective is to provide a mounting bracket; a fourth objective is to provide an instrument panel assembly; and a fifth objective is to provide a vehicle.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A central control display assembly includes: an instrument panel assembly having a mounting through hole and a positioning structure arranged circumferentially around the mounting through hole; a display screen having a rear shell portion and a connecting portion disposed within the rear shell portion; at least a portion of the rear shell portion being engaged within the positioning structure; a mounting bracket passing through the mounting through hole; and the mounting bracket being connected to the connecting portion for supporting the display screen.

[0007] Based on the aforementioned technical means, the display screen is positioned using the rear shell and positioning structure, and fixed using a mounting bracket. This utility model's central control display screen assembly simplifies the multi-functional integrated design of traditional adapter brackets by integrating the positioning function into the instrument panel assembly and separating the installation function into an independent mounting bracket. The mounting bracket only needs to bear the force transmission and connection functions, reducing structural complexity and thus reducing both the weight and volume of the mounting bracket. The reduced weight of the mounting bracket further reduces the weight of the central control display screen assembly, contributing to weight reduction. The reduced volume of the mounting bracket allows for a smaller mounting hole size, avoiding large-area hollowing out of the instrument panel assembly and ensuring its strength; furthermore, the reduced volume of the mounting bracket occupies less space, freeing up design space and facilitating the layout of other components.

[0008] Furthermore, the mounting bracket is provided with a dovetail groove, and at least a portion of the connecting part is inserted into the dovetail groove.

[0009] According to the above-mentioned technical means, at least part of the structure of the connecting part is inserted into the dovetail groove. The dovetail groove can provide a larger connection area for the connecting part, which is beneficial to improving the connection strength between the mounting bracket and the display screen. In addition, the dovetail groove can provide a certain deformation space, so even if the size of the connecting part is slightly deviated, the connecting part can still be fixed, which has high reliability.

[0010] Furthermore, the mounting bracket has a first arm and a second arm at the end furthest from the display screen, the first arm and the second arm intersect and are connected; the central control display screen assembly includes a support component, and both the first arm and the second arm are fixedly connected to the support component.

[0011] Based on the aforementioned technical means, the intersecting and connected first and second arms, together with the support components, form a triangular support structure. Compared to a straight arm structure, the triangular support structure has higher stability, meaning the connection between the mounting bracket and the support components is more stable. Furthermore, it can reduce material usage under the same strength, which is beneficial for the lightweighting of the mounting bracket and even the entire vehicle. At the same time, the force component design of the first and second arms can reduce the risk of single-point stress concentration and improve the rigidity of the mounting bracket.

[0012] Furthermore, the first arm is provided with a first plate portion, and the second arm is provided with a second plate portion; the support assembly includes a support cantilever, and the support cantilever is provided with a first support portion and a second support portion; the first support portion is disposed toward the first plate portion and is fixedly connected to the first plate portion; the second support portion is disposed toward the second plate portion and is fixedly connected to the second plate portion.

[0013] According to the aforementioned technical means, the first plate and the second plate respectively connect to the first and second support portions of the cantilever, forming a surface contact fixation. This increases the contact area between the first and second arms and the cantilever, thereby improving the connection strength between the first and second arms and the cantilever. Furthermore, due to its sufficient connection strength, this type of mounting bracket can be designed to be smaller than traditional mounting brackets, facilitating installation and transportation.

[0014] Furthermore, the instrument panel assembly includes a reinforcing bracket, at least a portion of which is located between the mounting bracket and the support cantilever; a first positioning hole is provided on a first plate, and a second positioning hole is provided on a second plate; a first positioning post and a second positioning post are provided on the reinforcing bracket, the first positioning post and the second positioning post respectively passing through the first positioning hole and the second positioning hole.

[0015] Based on the aforementioned technical means, the reinforced bracket achieves precise positioning of the mounting bracket through the cooperation of positioning posts and positioning holes, which helps improve the installation accuracy of the mounting bracket and thus the installation accuracy of the display screen. Furthermore, the first and second positioning posts of the reinforced bracket can pre-position the mounting bracket, avoiding assembly misalignment and improving installation efficiency. Simultaneously, the reinforced bracket fills the gap between the second end and the cantilever, enhancing local torsional rigidity and preventing the instrument panel components from sagging and deforming due to the weight of the display screen.

[0016] Furthermore, the instrument panel assembly includes an instrument panel having an edge structure extending around a mounting through-hole; a positioning structure is disposed on the edge structure.

[0017] Based on the above technical means, the positioning structure is set by using the rear shell of the display screen and the edge structure of the instrument panel itself, without the need to add additional positioning brackets, making full use of the existing component functions and reducing the number of parts; at the same time, the rear shell of the display screen is inserted into the edge structure of the instrument panel, which is conducive to controlling the surface difference gap between the display screen and the instrument panel, and the rear shell can cover the mounting through holes, which is aesthetically pleasing.

[0018] Furthermore, the positioning structure includes a hanging ear portion; the edge structure includes a first edge located above the mounting bracket, and at least one hanging ear portion is provided on the first edge; the rear shell portion includes a first wall opposite to the first edge, and at least a portion of the first wall is engaged within the hanging ear portion.

[0019] According to the above-mentioned technical means, the engagement between the ear and the first wall forms an upper constraint, and the upper part of the display screen is quickly fixed by gravity self-locking, which is convenient for assembly; and the first wall can cover the ear, realizing the hidden design of the ear and improving the aesthetics of the interior.

[0020] Furthermore, the positioning structure includes a positioning groove; the edge structure includes two second edges located on the left and right sides of the mounting bracket, and the second edges are provided with positioning grooves; the rear shell includes two second walls connected to both ends of the first wall, and at least a portion of the structure of the second wall is engaged in the positioning groove.

[0021] Based on the above technical means, the positioning grooves on both sides and the second wall form a lateral limit, which together with the hanging ear forms a three-point positioning system. This facilitates precise control of the installation position of the display screen, realizes uniform gap control between the display screen and adjacent components (such as the instrument panel and instrument trim panel), and further improves the aesthetics of the interior.

[0022] Furthermore, the instrument panel assembly includes an instrument trim panel, which is disposed adjacent to and below the rear housing.

[0023] Based on the aforementioned technical means, the instrument panel trim can cover the lower gap of the rear housing, thereby concealing the internal wiring harness and mounting brackets, further improving the aesthetics of the interior. Furthermore, anti-squeak foam can be installed on the rear-facing side of the instrument panel trim, reducing the possibility of abnormal noises from the display screen being transmitted to the passenger compartment.

[0024] A display screen has a rear housing and a connecting portion disposed within the rear housing; the rear housing is used to snap onto an instrument panel assembly; the connecting portion is used to connect to a mounting bracket.

[0025] According to the above-mentioned technical means, the rear shell of the display screen is snapped into the dashboard assembly to realize the positioning function of the display screen; the connecting part is connected to the mounting bracket to realize the supporting function of the display screen. The display screen of this utility model integrates the positioning function between the rear shell and the dashboard assembly, and separates the installation function between the connecting part and the mounting bracket, thereby achieving decoupling of positioning and fastening, simplifying the structure of the mounting bracket, and reducing the weight and space occupied by the mounting bracket.

[0026] Furthermore, the rear housing includes a first wall and two second walls connected to opposite sides of the first wall; at least a portion of the structure of the first wall and at least a portion of the structure of the two second walls are used for engaging with the instrument panel assembly.

[0027] Based on the above technical means, the first wall is snapped into the instrument panel component to realize the positioning function of the display screen in the vertical direction; the second wall is snapped into the instrument panel component to realize the positioning function of the display screen in the horizontal direction, thus ensuring the accuracy and reliability of the display screen positioning.

[0028] Furthermore, at least two connecting parts are provided at intervals, and the two connecting parts are respectively used to connect with two mounting brackets.

[0029] Based on the above technical means, the two connecting parts are used to connect with the two mounting brackets respectively, thereby improving the reliability and stability of the display screen support.

[0030] A mounting bracket has a first end and a second end opposite to each other. The first end is used to connect to a display screen. The second end has a first arm and a second arm, which intersect and connect to each other. The first arm and the second arm are used to fixably connect to a support assembly. According to the above technical means, the mounting bracket only serves to support the display screen, eliminating the need for screen positioning. This decoupling of positioning and fastening reduces the structural complexity of the mounting bracket, resulting in a reduction in both weight and volume. The reduced weight of the mounting bracket further reduces the weight of the central control display screen assembly, contributing to weight reduction. The reduced volume of the mounting bracket avoids large-area cutouts in the instrument panel components, ensuring their strength. Furthermore, the reduced volume of the mounting bracket occupies less space, freeing up design space and facilitating the layout of other components.

[0031] Furthermore, the first end is provided with a dovetail groove, which is used to connect with the connection part of the display screen.

[0032] Based on the above technical means, it is beneficial to improve the connection strength between the mounting bracket and the display screen; and the dovetail groove can provide a certain deformation space, so even if the size of the connection part is slightly off, the connection part can still be fixed, which is highly reliable.

[0033] Furthermore, the first arm is provided with a first plate portion, which is used to be fixedly connected to the first support portion of the support assembly; the second arm is provided with a second plate portion, which is used to be fixedly connected to the second support portion of the support assembly.

[0034] According to the above-mentioned technical means, the first plate and the second plate are respectively fixed in surface contact with the first support and the second support, thereby improving the connection strength between the mounting bracket and the support assembly. Furthermore, due to its sufficient connection strength, this type of mounting bracket can be designed to be smaller than traditional mounting brackets, facilitating installation and transportation.

[0035] Furthermore, the first plate is provided with a first positioning hole, which is used to position and cooperate with the first positioning post of the reinforcing bracket; the second plate is provided with a second positioning hole, which is used to position and cooperate with the second positioning post of the reinforcing bracket.

[0036] Based on the aforementioned technical methods, the precise positioning of the mounting bracket is achieved through the interlocking of the posts, which improves the installation accuracy of the mounting bracket and consequently, the installation accuracy of the display screen. Furthermore, the reinforced first and second positioning posts of the bracket can pre-position the mounting bracket, preventing misalignment during assembly and improving installation efficiency.

[0037] An instrument panel assembly has a mounting through hole and a positioning structure arranged circumferentially around the mounting through hole; the positioning structure is used to engage with a rear housing portion on the back of a display screen.

[0038] Based on the above technical means, the positioning function of the display screen is realized through the positioning structure of the instrument panel component, and the mounting bracket is only used to support the display screen, thus achieving decoupling between positioning and fastening, which helps to simplify the mounting bracket.

[0039] Furthermore, the instrument panel assembly includes an instrument panel having an edge structure extending around a mounting through-hole; a positioning structure is disposed on the edge structure.

[0040] Based on the above technical means, the positioning structure is set by utilizing the edge structure of the instrument panel itself, eliminating the need for additional positioning brackets, making full use of the existing component functions and reducing the number of parts; at the same time, it is beneficial to control the surface difference gap between the display screen and the instrument panel, and has a high aesthetic appeal.

[0041] Furthermore, the positioning structure includes a lug; the edge structure includes a first edge located above the mounting through hole, and at least one lug is provided on the first edge; the lug is used to engage with the first wall of the rear shell.

[0042] According to the above-mentioned technical means, the engagement between the ear and the first wall forms an upper constraint, and the upper part of the display screen is quickly fixed by gravity self-locking, which is convenient for assembly; and the first wall can cover the ear, realizing the hidden design of the ear and improving the aesthetics of the interior.

[0043] Furthermore, the positioning structure includes a positioning groove; the edge structure includes two second edges respectively connected to opposite sides of the first edge; the second edge is provided with a positioning groove, which is used to engage with the second wall of the rear shell.

[0044] Based on the above technical means, the positioning grooves on both sides and the second wall form a lateral limit, which together with the hanging ear forms a three-point positioning system. This facilitates precise control of the installation position of the display screen, realizes uniform gap control between the display screen and adjacent components (such as the instrument panel and instrument trim panel), and further improves the aesthetics of the interior.

[0045] Furthermore, the instrument panel assembly includes an instrument trim panel, which is disposed adjacent to and below the instrument panel, and together with the instrument panel, forms a mounting through hole.

[0046] Based on the aforementioned technical means, the instrument panel trim can conceal the internal wiring harness and mounting brackets within the mounting holes, further enhancing the aesthetics of the interior.

[0047] An automobile includes a vehicle body, the vehicle body having the aforementioned central control display assembly; or, the vehicle body having the aforementioned display; or, the vehicle body having the aforementioned mounting bracket; or, the vehicle body having the aforementioned instrument panel assembly.

[0048] The beneficial effects of this utility model are:

The mounting bracket only needs to bear the force transmission and connection functions, reducing structural complexity and thus reducing the weight and volume of the mounting bracket. The reduced weight of the mounting bracket, in turn, reduces the weight of the central control display assembly, contributing to weight reduction.

[0071] The embodiments of this utility model 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 utility model from the content disclosed in this specification. This utility model 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 utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0072] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In 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.

[0073] Existing automotive center console display adapter mounting brackets must meet requirements for positioning and fastening, as well as rigidity, strength, and modal characteristics. This results in relatively complex structures, heavy weight, large space occupancy, and limited design flexibility. To address these issues, this utility model provides a center console display assembly, a display screen, a mounting bracket, an instrument panel assembly, and an automotive vehicle.

[0074] On the one hand, this embodiment proposes a central control display assembly, such as Figures 1-4 As shown, the central control display assembly includes a display screen 1, a mounting bracket 2, an instrument panel assembly 3, and a support assembly 4. The display screen 1 is supported on the support assembly 4 via the mounting bracket 2, and the instrument panel assembly 3 is also supported on the support assembly 4. The support assembly 4 is used to connect to the floor inside the vehicle's passenger compartment.

[0075] Specifically, such as Figure 3 As shown, the instrument panel assembly 3 has a mounting through hole 30 and a positioning structure 310 arranged circumferentially around the mounting through hole 30. The back of the display screen 1 has a rear housing portion 11 and a connecting portion 12 disposed within the rear housing portion 11. It can be understood that the back of the display screen 1 specifically refers to the surface opposite to the image display surface of the display screen 1. A cavity is formed within the rear housing portion 11, and the connecting portion 12 is located within this cavity. A mounting bracket 2 passes through the mounting through hole 30 and connects the display screen 1 and the support assembly 4. Specifically, the mounting bracket 2 has a first end 21 and a second end 22, the first end 21 being connected to the connecting portion 12, and the second end 22 being connected to the support assembly 4. At least a portion of the structure of the rear housing portion 11 is engaged within the positioning structure 310.

[0076] In this embodiment, the rear shell 11 and the positioning structure 310 are used to position the display screen 1, and the mounting bracket 2 is used to fix the display screen 1. The central control display screen assembly of this utility model simplifies the multi-functional integrated design of traditional adapter brackets by integrating the positioning function into the instrument panel component 3 and separating the installation function into the independent mounting bracket 2. The mounting bracket 2 is only used for fixing, eliminating the need for positioning and limiting structures, thus reducing the structural complexity of the mounting bracket 2 and consequently reducing its weight and volume. The reduced weight of the mounting bracket 2 further reduces the weight of the central control display screen assembly, contributing to weight reduction. The reduced volume of the mounting bracket 2 allows for a smaller mounting hole 30, avoiding large-area hollowing out of the instrument panel component 3 and ensuring the strength of the instrument panel component 3; moreover, the reduced volume of the mounting bracket 2 reduces its space occupation, freeing up design space and facilitating the layout of other components. Furthermore, using the rear shell 11 and the instrument panel component 3 to position the display screen 1 reduces reliance on the support structure or the mounting bracket 2 for positioning, making it easier to control installation accuracy.

[0077] For ease of description, such as Figures 1-4 As shown, the X direction is the front-to-back direction of the car, the Y direction is the left-to-right direction of the car, and the Z direction is the up-to-down direction of the car. The X, Y, and Z directions are perpendicular to each other. The mounting bracket 2 has a first end 21 and a second end 22 that are opposite each other along the X direction; that is, the display screen 1 and the support assembly 4 are respectively connected to opposite ends of the mounting bracket 2 along the X direction.

[0078] The first end 21 of the mounting bracket 2 can be connected to the connecting part 12 by means of fastener connection, snap-fit, welding, etc., as long as the function of fixing the display screen 1 and the mounting bracket 2 can be realized.

[0079] Specifically, in some embodiments, the first end 21 of the mounting bracket 2 is provided with a dovetail groove 211, and at least a portion of the structure of the connecting part 12 is inserted into the dovetail groove 211. The design of the dovetail groove 211 can provide a larger connection area for the connecting part 12, which is beneficial to improving the connection strength between the mounting bracket 2 and the display screen 1; and the dovetail groove 211 can provide a certain deformation space, so even if the size of the connecting part 12 is slightly deviated, the connecting part 12 can still be fixed, resulting in high reliability.

[0080] Specifically, such as Figures 5-7As shown, the dovetail groove 211 forms an installation space for the connecting part 12 to be inserted, and the groove wall of the dovetail groove 211 has a notch, which provides deformation space for locking the connecting part 12. Exemplarily, both the groove wall of the dovetail groove 211 and the connecting part 12 can be provided with through holes extending in the Z direction, and the notch is provided on at least one side of the groove wall of the dovetail groove 211 in the Y direction. After fasteners such as screws are passed sequentially through the groove wall of the dovetail groove 211 and the through holes on the connecting part 12, the connecting part 12 is locked and fixed in the dovetail groove 211 by the cooperation of a nut and screw. The assembly method is simple and reliable.

[0081] The second end 22 of the mounting bracket 2 can be connected to the connecting part 12 by means of fastener connection, snap-fit, welding, etc., as long as the function of fixing the display screen 1 and the mounting bracket 2 can be realized.

[0082] Specifically, in some embodiments, such as Figures 5-7 As shown, the second end 22 is provided with a first arm 221 and a second arm 222, which intersect and connect. Both the first arm 221 and the second arm 222 are fixedly connected to the support assembly 4. This configuration forms a triangular support structure with the first arm 221, the second arm 222, and the support assembly 4. Compared to a straight arm structure, the triangular support structure has higher stability, meaning the connection between the mounting bracket 2 and the support assembly 4 is more stable. Furthermore, it reduces material usage while maintaining the same strength, facilitating the lightweighting of the mounting bracket 2 and even the entire vehicle. Simultaneously, the force-shaping design of the first arm 221 and the second arm 222 reduces the risk of single-point stress concentration and improves the rigidity of the mounting bracket 2.

[0083] For example, along the Z direction, the second arm 222 can be located below the first arm 221, and the second arm 222 can be perpendicular to the first arm 221. Of course, the first arm 221 and the second arm 222 can also form an acute angle or an obtuse angle, as long as they can match the connection structure of the support component 4 to achieve the corresponding fastening function.

[0084] The first arm 221 and the support assembly 4 can be connected by fasteners, snap-fit, welding, etc.; the second arm 222 and the support assembly 4 can also be connected by fasteners, snap-fit, welding, etc.

[0085] For example, such as Figure 12As shown, the support assembly 4 includes a support crossbeam 42, a support longitudinal beam 43, and a support cantilever 41. The support crossbeam 42 may be tubular and extends along the Y direction, supporting the instrument panel assembly 3. The support longitudinal beam 43 is fixedly connected to the support crossbeam 42 and extends along the Z direction. Two support longitudinal beams 43 may be spaced apart along the Y direction, connecting to the floor in the vehicle's passenger compartment. The support cantilever 41 may be located between two support longitudinal beams 43 and fixedly connected to both support longitudinal beams 43 and the support crossbeam 42. Exemplarily, the support crossbeam 42, support longitudinal beam 43, and support cantilever 41 can be connected by fasteners, welding, etc., preferably welding for higher reliability.

[0086] Furthermore, in some embodiments, the first arm 221 is provided with a first plate portion 2211, and the second arm 222 is provided with a second plate portion 2221. The supporting cantilever 41 is provided with a first support portion 411 and a second support portion 412. The first support portion 411 is disposed facing the first plate portion 2211 and is fixedly connected to the first plate portion 2211. The second support portion 412 is disposed facing the second plate portion 2221 and is fixedly connected to the second plate portion 2221. In this embodiment, the first plate portion 2211 and the second plate portion 2221 respectively abut against the first support portion 411 and the second support portion 412 of the supporting cantilever 41, forming a surface contact fixation, which increases the contact area between the first arm 221 and the second arm 222 and the supporting cantilever 41, thereby improving the connection strength between the first arm 221 and the second arm 222 and the supporting cantilever 41. Moreover, the mounting bracket 2 configured in this way has sufficient connection strength, and its size can be designed to be smaller than that of a traditional mounting bracket 2, which is beneficial for installation and transportation.

[0087] For example, both the first support portion 411 and the second support portion 412 may be provided with bolt posts, and both the first plate portion 2211 and the second plate portion 2221 are provided with corresponding first through holes. After the bolt post of the first support portion 411 passes through the first through hole on the first plate portion 2211, the first plate portion 2211 and the first support portion 411 are locked and fixed by the nut and the bolt post. After the bolt post of the second support portion 412 passes through the first through hole on the second plate portion 2221, the second plate portion 2221 and the second support portion 412 are locked and fixed by the nut and the bolt post.

[0088] Furthermore, such as Figure 2 , Figure 3 and Figure 13As shown, the instrument panel assembly 3 includes a reinforcing bracket 33, at least a portion of which is located between the second end 22 and the supporting cantilever 41. The first plate portion 2211 has a first positioning hole 2212, and the second plate portion 2221 has a second positioning hole 2222. The reinforcing bracket 33 has a first positioning post 331 and a second positioning post 332, which are respectively inserted into the first positioning hole 2212 and the second positioning hole 2222. This arrangement allows the reinforcing bracket 33 to achieve precise alignment between the mounting bracket 2 and the supporting cantilever 41 through the cooperation of the positioning posts and positioning holes, improving the installation accuracy of the mounting bracket 2 and consequently, the installation accuracy of the display screen 1. Furthermore, since at least a portion of the reinforcing bracket 33 is located between the second end 22 and the supporting cantilever 41, the first positioning post 331 and the second positioning post 332 of the reinforcing bracket 33 can pre-position the mounting bracket 2, preventing misalignment and improving installation efficiency. At the same time, the reinforced bracket 33 fills the gap between the second end 22 and the cantilever, enhances the local torsional stiffness, and prevents the instrument panel assembly 3 from sagging and deforming due to the weight of the display screen 1.

[0089] For example, the reinforcing bracket 33 is also provided with two second through holes that are respectively opposite to the two first through holes. The bolts of the first support part 411 and the second support part 412 can pass through the second through holes and the first through holes in sequence, and the mounting bracket 2, the reinforcing bracket 33 and the support cantilever 41 are locked and fixed by using nuts.

[0090] To improve stability, the mounting brackets 2 can be provided in at least two sets, i.e., two, three, four, or other quantities. Correspondingly, the connecting part 12 of the display screen 1 can also be provided in at least two sets, and the first support part 411 and the second support part 412 of the supporting cantilever 41 can also be provided in two sets. For example, the mounting brackets 2 can be provided in two sets spaced apart along the Y direction, namely a first mounting bracket 2a and a second mounting bracket 2b, both of which are connected between the display screen 1 and the support assembly 4. The first plate portion 2211 and the second plate portion 2221 of the first mounting bracket 2a are located on the side opposite to the second mounting bracket 2b, and the first plate portion 2211 and the second plate portion 2221 of the second mounting bracket 2b are located on the side opposite to the first mounting bracket 2a. This facilitates the provision of wiring space between the first mounting bracket 2a and the second mounting bracket 2b, allowing for the arrangement of wire harnesses and other components.

[0091] For example, the mounting bracket 2 can be integrally formed, such as by stamping, which is simple to manufacture and has low manufacturing cost.

[0092] Furthermore, such as Figure 2 , Figures 13-16As shown, the instrument panel assembly 3 includes an instrument panel 31, an instrument panel frame 32, the aforementioned reinforcing bracket 33, and an instrument panel trim panel 34. Along the Z-direction, the instrument panel frame 32 covers and connects to the reinforcing bracket 33. The instrument panel frame 32 and the reinforcing bracket 33 can be connected by fasteners, welding, snap-fit, etc. Both the instrument panel frame 32 and the reinforcing bracket 33 can be connected to the support assembly 4 to further ensure the overall structural reliability of the hollow display screen 1 assembly. Along the X-direction, the front ends of the instrument panel frame 32 and the reinforcing bracket 33 together form the aforementioned mounting through hole 30. The instrument panel 31 is located above the mounting through hole 30 and is connected to the instrument panel frame 32. The instrument panel 31 and the instrument panel frame 32 can be connected by fasteners, welding, snap-fit, etc. The instrument panel trim panel 34 is located below the mounting through hole 30 and can also be directly or indirectly connected to the instrument panel frame 32.

[0093] The instrument panel 31 has an edge structure 311 extending around the mounting through hole 30, and a positioning structure 310 can be disposed on the edge structure 311. By utilizing the rear shell portion 11 of the display screen 1 and the edge structure 311 of the instrument panel 31 itself to set the positioning structure 310, there is no need to add an additional positioning bracket, making full use of the existing component functions and reducing the number of parts. At the same time, the rear shell portion 11 of the display screen 1 is fitted into the edge structure 311 of the instrument panel 31, which is conducive to controlling the surface difference gap between the display screen 1 and the instrument panel 31, and the rear shell portion 11 can cover the mounting through hole 30, which is aesthetically pleasing.

[0094] Specifically, such as Figures 8-11 As shown, the rear shell 11 has a first wall 111, a third wall 113 and two second walls 112. The two second walls 112 are connected between the first wall 111 and the third wall 113. The first wall 111, the second wall and the third wall 113 together enclose the cavity.

[0095] Furthermore, the positioning structure 310 may include a hanging ear portion 3101. The edge structure 311 of the instrument panel 31 extending around the mounting through hole 30 includes a first edge 3111 located above the mounting bracket 2, and at least one hanging ear portion 3101 is provided on the first edge 3111. The first wall 111 of the rear shell portion 11 is opposite to the first edge 3111, and at least a portion of the structure of the first wall 111 is engaged within the hanging ear portion 3101. In this embodiment, the engagement between the hanging ear portion 3101 and the first wall 111 forms an upper constraint, and the upper end of the display screen 1 is quickly fixed by gravity self-locking, which is convenient for assembly. Moreover, the first wall 111 can cover the hanging ear portion 3101, realizing the hidden design of the hanging ear portion 3101 and improving the aesthetics of the interior.

[0096] For example, such as Figure 4 and Figure 15As shown, two loops 3101 may be provided at intervals on the first edge 3111, and at least a portion of the structure of the first wall 111 is engaged within the two loops 3101. Of course, three, four, five or other numbers of loops 3101 may also be provided on the first edge 3111.

[0097] Furthermore, the positioning structure 310 may also include a positioning groove 3102. The edge structure 311 extending around the mounting through hole 30 of the instrument panel 31 also includes two second edges 3112 located on the left and right sides of the mounting bracket 2, respectively, and each of the two second edges 3112 is provided with a positioning groove 3102. The two second walls 112 of the rear shell portion 11 are respectively connected to the two ends of the first wall 111, and the two second walls 112 are respectively opposite to the two second edges 3112. At least a portion of the structure of the second wall 112 is engaged in the positioning groove 3102. In this embodiment, the positioning grooves 3102 on both sides and the second walls 112 form a lateral limit, which, together with the hanging ear portion 3101, constitutes a three-point positioning system, which is conducive to accurately controlling the installation position of the display screen 1, realizing uniform gap control between the display screen 1 and adjacent components (such as the instrument panel 31 and the instrument decorative panel 34), and further improving the aesthetics of the interior.

[0098] For example, such as Figure 4 and Figure 15 As shown, the side wall of the positioning groove 3102 can also be provided with reinforcing ribs and other reinforcing structures. The reinforcing structures abut against the second wall 112, which can not only improve the structural strength of the positioning groove 3102, but also enhance the stability of the display screen 1 by abutting against the second wall 112.

[0099] Furthermore, the aforementioned instrument panel trim 34 is disposed adjacent to and below the rear housing 11. For example... Figure 16 As shown, a groove 341 is formed on the instrument panel trim 34, and at least a portion of the third wall 113 and the two second walls 112 of the rear housing 11 are located within the groove 341. In this embodiment, the instrument panel trim 34 can cover the lower gap of the rear housing 11, thereby concealing the internal wiring harness and mounting bracket 2, further improving the aesthetics of the interior. Exemplarily, the side of the instrument panel trim 34 facing the rear housing 11 may also be provided with anti-noise foam to reduce the possibility of noise from the display screen 1 being transmitted to the cockpit.

[0100] On another front, this embodiment proposes a display screen 1, with a rear shell portion 11 and a connecting portion 12 disposed within the rear shell portion 11 on its back. The rear shell portion 11 is used to engage with the instrument panel assembly 3; the connecting portion 12 is used to connect with the mounting bracket 2. In this embodiment, the rear shell portion 11 of the display screen 1 engages with the instrument panel assembly 11 to achieve the positioning function of the display screen 1; the connecting portion 12 connects with the mounting bracket 2 to achieve the supporting function of the display screen 1. By integrating the positioning function between the rear shell portion 11 and the instrument panel assembly 11 and separating the installation function between the connecting portion 12 and the mounting bracket 2, the display screen 1 of this utility model achieves decoupling of positioning and fastening, simplifies the structure of the mounting bracket 2, and reduces the weight and space occupied by the mounting bracket 2.

[0101] Furthermore, in some embodiments, the rear housing 11 includes a first wall 111 and two second walls 112 connected to opposite sides of the first wall 111; at least a portion of the structure of the first wall 111 and at least a portion of the structure of the two second walls 112 are used to engage with the instrument panel assembly 3. In this embodiment, the engagement of the first wall 111 with the instrument panel assembly 3 enables the vertical positioning function of the display screen 1; the engagement of the second walls 112 with the instrument panel assembly 3 enables the horizontal positioning function of the display screen 1, ensuring the accuracy and reliability of the positioning of the display screen 1.

[0102] Furthermore, in some embodiments, at least two connecting portions 12 are spaced apart, and each connecting portion 12 is used to connect to one of the two mounting brackets 2. In this embodiment, the two connecting portions 12 are used to connect to the two mounting brackets 2 respectively, thereby improving the reliability and stability of the display screen 1 support.

[0103] On another front, this embodiment proposes a mounting bracket 2, which has a first end 21 and a second end 22. The first end 21 is used to connect to the display screen 1. The second end 22 is provided with a first arm 221 and a second arm 222, which intersect and connect with each other; the first arm 221 and the second arm 222 are used to fix and connect to the support component 4. In this embodiment, the mounting bracket 2 is only used to support the display screen 1, without the need to position the display screen 1, thus achieving decoupling between positioning and fastening, reducing the structural complexity of the mounting bracket 2, and reducing its weight and volume. The reduced weight of the mounting bracket 2 further reduces the weight of the central control display screen assembly, which is beneficial for weight reduction. The reduced volume of the mounting bracket 2 avoids large-area hollowing out of the instrument panel component 3, which is beneficial for ensuring the strength of the instrument panel component 3; moreover, the reduced volume of the mounting bracket 2 reduces the space it occupies, freeing up design space and facilitating the layout of other components.

[0104] Furthermore, in some embodiments, the first end 21 is provided with a dovetail groove 211, which is used to connect with the connecting part 12 of the display screen 1. In this embodiment, the design of the dovetail groove 211 is beneficial to improving the connection strength between the mounting bracket 2 and the display screen 1; and the dovetail groove 211 can provide a certain deformation space, so even if the size of the connecting part 12 is slightly deviated, the connecting part 12 can still be fixed, resulting in high reliability.

[0105] Furthermore, in some embodiments, the first arm 221 is provided with a first plate portion 2211, which is used to be fixedly connected to the first support portion 411 of the support assembly 4; the second arm 222 is provided with a second plate portion 2221, which is used to be fixedly connected to the second support portion 412 of the support assembly 4. In this embodiment, the first plate portion 2211 and the second plate portion 2221 respectively form surface contact with the first support portion 411 and the second support portion 412, thereby improving the connection strength between the mounting bracket 2 and the support assembly 4. Moreover, the mounting bracket 2 configured in this way has sufficient connection strength, and its size can be designed to be smaller than that of a traditional mounting bracket 2, which is beneficial for installation and transportation.

[0106] Furthermore, in some embodiments, the first plate portion 2211 is provided with a first positioning hole 2212, which is used for positioning and engaging with the first positioning post 331 of the reinforcing bracket 33; the second plate portion 2221 is provided with a second positioning hole 2222, which is used for positioning and engaging with the second positioning post 332 of the reinforcing bracket 33. In this embodiment, the precise positioning of the mounting bracket 2 is achieved through the hole-post engagement, which helps to improve the installation accuracy of the mounting bracket 2, thereby improving the installation accuracy of the display screen 1. Moreover, the first positioning post 331 and the second positioning post 332 of the reinforcing bracket 33 can play a pre-positioning role for the mounting bracket 2, avoiding assembly misalignment and improving installation efficiency.

[0107] On another front, this embodiment proposes an instrument panel assembly 3, which has a mounting through hole 30 and a positioning structure 310 arranged circumferentially around the mounting through hole 30; the positioning structure 310 is used to engage with the rear shell portion 11 on the back of the display screen 1. In this embodiment, the positioning function of the display screen 1 is realized through the positioning structure 310 of the instrument panel assembly 3, and the mounting bracket 2 is only used to realize the support function of the display screen 1, thus achieving decoupling of positioning and fastening, which helps to simplify the mounting bracket 2.

[0108] Furthermore, in some embodiments, the instrument panel assembly 3 includes an instrument panel 31 having an edge structure 311 extending around the mounting through hole 30; a positioning structure 310 is disposed on the edge structure 311. In this embodiment, the positioning structure 310 is set using the edge structure 311 of the instrument panel 31 itself, eliminating the need for additional positioning brackets, fully utilizing the functional integration of existing components, and reducing the number of parts; at the same time, it facilitates the control of the surface gap between the display screen 1 and the instrument panel 31, and also improves aesthetics.

[0109] Furthermore, in some embodiments, the positioning structure 310 includes a hanging ear portion 3101; the edge structure 311 includes a first edge 3111 located above the mounting through hole 30, and at least one hanging ear portion 3101 is provided on the first edge 3111; the hanging ear portion 3101 is used to engage with the first wall 111 of the rear shell portion 11. In this embodiment, the engagement between the hanging ear portion 3101 and the first wall 111 forms an upper constraint, and the upper end of the display screen 1 is quickly fixed by gravity self-locking, which is convenient for assembly; and the first wall 111 can cover the hanging ear portion 3101, realizing the hidden design of the hanging ear portion 3101 and improving the aesthetics of the interior.

[0110] Furthermore, in some embodiments, the positioning structure 310 includes a positioning groove 3102; the edge structure 311 includes two second edges 3112 respectively connected to opposite sides of the first edge 3111; the second edge 3112 is provided with a positioning groove 3102, which is used to engage with the second wall 112 of the rear shell portion 11. In this embodiment, the positioning grooves 3102 on both sides and the second wall 112 form a lateral limit, which together with the hanging ear portion 3101 constitutes a three-point positioning system, which is conducive to accurately controlling the installation position of the display screen 1, realizing uniform gap control between the display screen 1 and adjacent components such as the instrument panel 31 and the instrument trim panel 34, and further improving the aesthetics of the interior.

[0111] Furthermore, in some embodiments, the instrument panel assembly 3 includes an instrument trim panel 34, which is disposed adjacent to and below the instrument panel 31, and together with the instrument panel 31, encloses a mounting through hole 30. In this embodiment, the instrument trim panel 34 can conceal the internal wiring harness and mounting bracket 2 within the mounting through hole 30, further improving the aesthetics of the interior. Exemplarily, the side of the instrument trim panel 34 facing the rear housing 11 may also be provided with anti-noise foam to reduce the possibility of noise from the display screen 1 being transmitted to the passenger compartment.

[0112] On the other hand, this embodiment proposes an automobile, including a vehicle body, the vehicle body being provided with the aforementioned central control display assembly; or, the vehicle body being provided with the aforementioned display screen 1; or, the vehicle body being provided with the aforementioned mounting bracket 2; or, the vehicle body being provided with the aforementioned instrument panel assembly 3. Since the automobile of this utility model includes the aforementioned central control display assembly, display screen 1, mounting bracket 2, or instrument panel assembly 3, the automobile of this utility model can achieve decoupling of the positioning and fastening of the display screen 1, simplifying the structure of the mounting bracket 2, resulting in many advantages such as reducing the weight and volume of the mounting bracket 2 and lowering tooling costs.

[0113] The present invention relates to a central control display assembly, a display screen 1, a mounting bracket 2, an instrument panel assembly 3, and a vehicle. By integrating the positioning function into the instrument panel assembly 3, precise positioning is achieved by utilizing the structure of the display screen 1 itself and the positioning structure 310 of the instrument panel assembly 3. The mounting bracket 2 is used to fasten the display screen 1 to the support assembly 4, effectively decoupling the positioning and fastening. This simplifies the structure of the mounting bracket 2 and generates many advantages such as reducing the weight and volume of the mounting bracket 2 and reducing tooling costs.
