[0026] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] An embodiment of the present application provides a floating central control screen back cover installation structure, which can solve the technical problem in the prior art that the central control screen back cover is inconvenient to install due to the relatively small space between the instrument panel and the central control screen.

[0028] The installation structure of the floating center control screen rear cover in this application includes a housing assembly and a connection assembly. The housing assembly is modularly arranged and wrapped around the outer periphery of the internal components of the floating center control screen. The connection assembly is arranged on the housing assembly and is used to quickly connect each module in the housing assembly, improving the convenience of installation work.

[0029] Specifically, Figure 1 is a schematic diagram of the appearance of an installation structure of a floating center control screen rear cover provided by an embodiment of this application. As Figure 1 shown, the housing assembly includes a screen mounting shell 1 and a connection rear shell 2 that is detachably connected to the back of the screen mounting shell 1 and axially penetrates. Figure 2 is a schematic diagram of the structure of the split rear shell 201 in an installation structure of a floating center control screen rear cover provided by an embodiment of this application. As Figure 2 shown, the connection rear shell 2 includes two split rear shells 201 arranged relatively left and right.

[0030] The screen mounting shell 1 has a certain thickness. Its front surface is provided with a decorative frame. The liquid crystal display screen is placed in the decorative frame and fixed by tape connection. The screen mounting shell 1 and the decorative frame are fixed by snap connection. In the space inside the screen mounting shell 1, a circuit board device assembly is arranged to实现 body electrical connection. In the traditional center control screen assembly, there is also a metal bracket for connecting the center control screen assembly and the vehicle body. Therefore, the rear shell in this application is axially through - type to wrap around the outer periphery of the metal bracket. One end of the metal bracket is connected to the back of the circuit board device assembly, and the other end passes through and extends out of the connection rear shell 2 to connect the vehicle body.

[0031] As an optional embodiment, based on the left - right split design of the connection rear shell 2, the cross - section of the connection rear shell 2 is square and the connection rear shell 2 axially penetrates. Therefore, the cross - section of a single split rear shell 201 facing the screen mounting shell 1 is in a C - shape, which has two horizontally parallel sides arranged up and down and a vertical side connecting the same - side ends of the two horizontal sides, and there is an opening on the side opposite to the vertical side. During assembly, the opening ends of the two connection rear shells 2 face each other and contact after assembly.

[0032] The screen mounting shell 1 and the connection rear shell 2 are made of the same material. Generally, high - performance plastics such as polycarbonate are used, which have good durability and impact resistance, and at the same time, the cost is relatively low, suitable for mass production. Or lightweight metals such as aluminum alloy are used, which not only have sufficient strength and rigidity but also can reduce weight and improve the fuel economy of the vehicle. At the same time, the metal material can also enhance the overall texture and sense of technology of the floating center control screen. The specific material is determined according to the actual use scenario and is not specifically limited in this application.

[0033] Furthermore, see Figure 2The connecting component includes a connecting frame located on the back of the screen mounting shell 1 and matching the cross-section of the connecting rear shell 2, and a mating end located at the end of the split rear shell 201. The connecting frame is a frame formed by two horizontally arranged guide rails 3 and two vertically arranged first snap-fit ​​units 4. The mating end includes guide ribs 5 located on the two horizontal sides of the split rear shell 201 to adapt to the guide rails 3, and a second snap-fit ​​unit 6 located on the vertical side of the split rear shell 201 to cooperate with one of the first snap-fit ​​units 4.

[0034] The two guide rails 3 are arranged at intervals in the upper and lower horizontal directions, corresponding to the two horizontal sides of a single split rear shell 201, so as to cooperate with the guide ribs 5 on the two horizontal sides of the split rear shell 201 to achieve precise positioning between the split rear shell 201 and the screen mounting shell 1 and between the two split rear shells 201. The two first locking units 4 are arranged longitudinally, corresponding to the vertical sides of each single split rear shell 201 respectively, so as to cooperate with the second locking units 6 on the vertical sides of the split rear shell 201 to achieve the connection between the screen mounting shell 1 and the connecting rear shell 2. The two guide rails 3 and the two first locking units 4 are connected end to end to form a square frame body, so as to correspond to the end face of the connecting rear shell 2 composed of the two split rear shells 201 facing the screen mounting shell 1.

[0035] Combined with the above description, after the assembly is completed, the vertical edges of the two split rear shells 201 are away from each other. Therefore, during assembly, the guide ribs 5 in the split rear shell 201 first contact the guide rail 3 and slide horizontally along the guide rail 3. The distance between the first snap-fit ​​unit 4 and the second snap-fit ​​unit 6 is reduced until the split rear shell 201 slides into place, the first snap-fit ​​unit 4 contacts the second snap-fit ​​unit 6 and automatically snaps in, completing the installation.

[0036] In existing vehicle designs, the longitudinal distance between the instrument panel and the central control screen is generally narrow, but the lateral distance is relatively wide. Therefore, the floating central control screen back cover installation structure in the present application can realize left-right assembly by setting a connecting back shell 2 that can be split left and right on the back of the screen mounting shell 1, which can avoid the limitation of the longitudinal installation space and improve the convenience of installation. At the same time, by setting mutually cooperating guide rails 3 and guide ribs 5, as well as mutually cooperating first snap-fitting units 4 and second snap-fitting units 6, when the two split back shells 201 slide into place, multiple modules are automatically snapped together, further reducing the tediousness of assembly work.

[0037] Furthermore, the length of the guide rib 5 is half the length of the guide rail 3. Combined with the above description, the guide ribs 5 on the same side of the two split rear shells 201 are located on the same guide rail 3. In order to improve the tightness of the assembly and reduce structural gaps, after the assembly is completed, the sum of the lengths of the guide ribs 5 on the same side of the two split rear shells 201 is consistent with the length of a single guide rail 3.

[0038] Further, Figure 3This is a structural diagram of the first engaging unit 4 in a floating central control screen rear cover installation structure provided in an embodiment of the present application, as shown in FIG. Figure 3 As shown, the connecting frame further includes a connecting bottom frame 7 connected to the screen mounting shell 1 , and the guide rail 3 and the first engaging unit 4 are both arranged on a side surface of the connecting bottom frame 7 facing the split rear shell 201 .

[0039] The bottom surface of the connecting bottom frame 7 is fixedly connected to the back of the screen mounting shell 1 to form a whole, and the top surface of the connecting bottom frame 7 is provided with a guide rail 3 and a first snap-fit ​​unit 4. The connecting bottom frame 7 has a certain height. On the one hand, it is to reserve Z-direction space for higher devices on the circuit board; on the other hand, it is to increase the distance between the first snap-fit ​​unit 4 and the connecting bottom frame 7, so as to facilitate the connection between the first snap-fit ​​unit 4 and the second snap-fit ​​unit 6.

[0040] Furthermore, the first engaging unit 4 includes a plurality of first limiting plates 401 spaced apart along the height direction of the screen mounting shell 1 and extending in a direction away from the screen mounting shell 1. The first limiting plates 401 are provided with first limiting holes 402. The first limiting plates 401 are arranged perpendicular to the screen mounting shell 1 as a whole. The bottom of the first limiting plates 401 is fixedly connected to the top of the connecting bottom frame 7 to form a whole. The top of the first limiting plates 401 extends a certain distance toward the direction close to the split rear shell 201. The number of first limiting plates 401 is not specifically limited in this application, but multiple first limiting plates 401 are arranged equidistantly. As an optional embodiment, based on the size of the connecting rear shell 2 and the connection stability, the number of first limiting plates 401 is preferably two.

[0041] Furthermore, the second engaging unit 6 includes first limiting posts 601 , the number of which is the same as the number of the first limiting plates 401 . The first limiting posts 601 extend horizontally in a direction away from the split rear housing 201 .

[0042] After the assembly is completed, the first limiting posts 601 in the two-part rear shells 201 approach each other, the guide rib 5 slides horizontally along the guide track 3, and the first limiting post 601 begins to approach the first limiting plate 401. The inner diameter of the first limiting hole 402 on the first limiting plate 401 is slightly larger than the outer diameter of the first limiting post 601. When the guide rib 5 slides into place, the first limiting post 601 is also embedded in the first limiting hole 402. The two are used together to facilitate the precise positioning between the two-part rear shells 201 and the screen mounting shell 1, thereby improving the convenience of assembly work.

[0043] Furthermore, the concave area between two adjacent first limiting plates 401 forms a first latch 403. In combination with the above description, the first limiting plates 401 extend toward the split rear shell 201, and a concave area is formed between the two adjacent first limiting plates 401, namely the first latch 403. The bottom surface of the first latch 403 coincides with the top surface of the connection bottom frame 7. The number of first latches 403 mainly depends on the number of first limiting plates 401. Based on the consideration of connection stability, the number of first latches 403 is equal to the number of first limiting plates 401, preferably two. As an optional embodiment, a protrusion is provided on the top surface of the connection bottom frame 7. The protrusion faces the same direction as the first limiting plates 401. The protrusion and the outermost first limiting plates 401 can also form a first latch 403. In this way, the configuration of two first limiting plates 401 and two first latches 403 can be achieved.

[0044] Furthermore, between two adjacent first limiting posts 601 there are first clips 602 with the same number as the first clips 403 , and the orientation of the first clips 602 is consistent with that of the first limiting posts 601 , that is, after assembly, the first clips 602 in the two split rear shells 201 are close to each other.

[0045] The first clip 602 includes a vertical plate, the free end of which is folded back toward the screen mounting shell 1. The working mechanism of the first clip 602 is consistent with the working mechanism of the first limiting column 601. When the guide rib 5 slides into place, the vertical plate of the first clip 602 passes through the first bayonet 403, and the folded area at its end is engaged with the inner wall of the connecting bottom frame 7.

[0046] Based on the working mechanism of the first clip 602, the horizontal length of the first clip 602 is limited. After the guide rib 5 slides into place, the folded area of ​​the first clip 602 needs to be just engaged with the inner wall of the connecting bottom frame 7, and the first limiting column 601 only needs to pass through the first limiting hole 402. There is no specific restriction on its length, which can ensure that it does not affect the normal assembly and installation work.

[0047] During assembly, the two-part rear shell 201 slides horizontally on the screen mounting shell 1 with the help of the guide rib 5 and gradually approaches each other. When the guide rib 5 slides into place, the opposite ends of the two-part rear shell 201 contact each other, and the first limiting column 601 passes through the first limiting hole 402, and the first buckle 602 engages with the first bayonet 403. At this point, the connection between the rear shell 2 and the screen mounting shell 1 is completed.

[0048] Furthermore, due to the modular design of the floating central control screen back cover installation structure in this application, it is necessary not only to consider the connection stability between the screen mounting shell 1 and the two-part rear shell 201, but also to consider the stable connection of the two-part rear shell 201 itself. Therefore, in this application, a rear shell snap-fit ​​unit is provided on the contact edge of the two-part rear shell 201 to achieve assembly convenience and connection stability between the two-part rear shell 201.

[0049] Specifically, Figure 4 This is a structural diagram of a split rear shell 201 in a floating central control screen rear cover installation structure provided in an embodiment of the present application. Figure 5 This is a structural diagram of another split rear shell 201 in a floating central control screen rear cover installation structure provided in an embodiment of the present application, as shown in FIG. Figure 4 、 Figure 5 As shown, the rear shell engaging unit includes a plurality of opening structures 8 located on one of the split rear shells 201 and a protruding structure 9 located on the other split rear shell 201 and engaging with the opening structures 8 .

[0050] As an optional embodiment, for the convenience of description, the two split rear shells 201 are respectively referred to as the left rear shell and the right rear shell. The opening structure 8 is located on the left rear shell, which includes two second limiting plates arranged at intervals. The second limiting plates extend toward the inside of the left rear shell. The two second limiting plates are arranged along one side of the left rear shell. One of the second limiting plates is provided with a second limiting through hole, and the other second limiting plate is provided with a second bayonet. The protruding structure 9 is provided on the right rear shell, which includes a second limiting column and a second buckle. When the two split rear shells 201 are in contact, the second limiting column passes through the second limiting through hole of one of the second limiting plates, and the second buckle passes through the second bayonet on the other second limiting plate to realize the connection between the two split rear shells 201.

[0051] During actual use, the shape of the split rear shell 201 may be different. Therefore, there is no specific restriction on the setting position of the opening structure 8 and the protruding structure 9 in this application. However, it is necessary to ensure that the two are respectively located on the contact edges of the two split rear shells 201 and after the two split rear shells 201 are in contact, the opening structure 8 and the protruding structure 9 can be engaged with each other. The above method is only an example.

[0052] Furthermore, in combination with the above description, a metal bracket for connecting the central control screen assembly and the vehicle body is also provided in the traditional central control screen assembly. Most of the metal brackets are now bent downward to facilitate the connection between the central control screen assembly and the vehicle body. Therefore, as an optional embodiment, the split rear shell 201 in this application is also bent downward, which includes a horizontal section for connecting to the screen mounting shell 1 and a vertical section for connecting to the vehicle body, and the mating end is located on the end face of the horizontal section facing the screen mounting shell 1.

[0053] The assembly method of the floating central control screen back cover installation structure in this application is as follows: the two split rear shells 201 slide horizontally along the guide track 3 and approach each other until the opposite surfaces of the split rear shells 201 contact each other. At the same time, the split rear shells 201 and the screen mounting shell 1 are automatically connected through the first snap unit 4 and the second snap unit 6, and the two split rear shells 201 are automatically connected through the rear shell snap unit.

[0054] The floating central control screen back cover installation structure in the present application can realize left-right assembly by setting a left and right split connecting back shell 2 on the back of the screen installation shell 1, reducing the installation space limitation, and by setting mutually cooperating guide rails 3 and guide ribs 5, as well as mutually cooperating first snap-fitting units 4 and second snap-fitting units 6, it can accurately position and quickly snap-fit, thereby improving the convenience of assembly work. Furthermore, the split back shells 201 set relatively on the left and right have their joints located at the top and bottom, which can better hide the joints and improve the aesthetics.
