[0029] As Figure 1 、 Figure 2 and Figure 3 shown, the present utility model discloses a vehicle-mounted main unit, which can be used as a central control device of an automobile, and a user can control other systems such as an air conditioner, a navigation system, and a video and audio player through the vehicle-mounted main unit. The vehicle-mounted main unit includes a housing 1, a screen pressing bracket 2, and a display screen 3. The housing 1 includes a shell body 11 and an inverted buckle 12, and the inverted buckle 12 is arranged on the inner side wall of the shell body 11; the screen pressing bracket 2 is arranged in the shell body 11, the screen pressing bracket 2 includes a bracket main body portion 21 and a bent portion 22, the bent portion 22 is connected to the bracket main body portion 21, and the bent portion 22 cooperates with the inverted buckle 12 to connect the bracket main body portion 21 and the shell body 11; the display screen 3 is arranged in the shell body 11, and the display screen 3 is arranged between the screen pressing bracket 2 and the housing 1.

[0030] In this embodiment, the in-vehicle host may include a housing 1, a screen pressing bracket 2, and a display screen 3. The housing 1 may be a plastic housing 1, which may be in an overall cuboid box shape. In some environments, due to the characteristics of the housing 1 material, a certain degree of deformation may occur. The space inside the housing 1 can be used to assemble electronic components such as a PCB. The screen pressing bracket 2 and the display screen 3 are both arranged inside the housing 1. The display screen 3 can be electrically connected to components such as the PCB and is used to display the working status and function modules of the in-vehicle host. The display screen 3 is specifically arranged between the screen pressing bracket 2 and the housing 1. The screen pressing bracket 2 is in an overall flat shape and may be a metal screen pressing bracket 2. On the one hand, the screen pressing bracket 2 cooperates with the housing 1 to limit the display screen 3 to prevent the display screen 3 from moving inside the housing 1. On the other hand, the screen pressing bracket 2 is arranged inside the housing 1 and connected to the housing 1. Because the screen pressing bracket 2 has a high hardness, it can prevent the housing 1 from deforming outwards or inwards.

[0031] Specifically, the housing 1 may include a housing body 11 and an inverted buckle 12. The screen pressing bracket 2 and the display screen 3 are both arranged inside the housing body 11. The inverted buckle 12 is arranged inside the housing body 11. The inverted buckle 12 can be integrally formed with the housing body 11. The inverted buckle 12 is used to cooperate with the screen pressing bracket 2 to connect the screen pressing bracket 2 and the housing body 11. The screen pressing bracket 2 may include a bracket main body portion 21 and a bent-up portion 22. The bent-up portion 22 is connected to the edge of the bracket main body portion 21. The bent-up portion 22 cooperates with the inverted buckle 12 to connect the bracket main body portion 21 and the housing body 11, that is, the bracket main body portion 21 hooks the housing body 11 through the bent-up portion 22 and the inverted buckle 12. Thus, when the housing body 11 has a tendency to deform outwards, the bracket main body portion 21 arranged inside the housing body 11 can pull the housing body 11 to prevent the housing body 11 from deforming outwards. Compared with the traditional screw fixing method, the structure of the in-vehicle host provided in this embodiment has good consistency, is convenient to assemble, and the fixing method is reliable. It can avoid opening holes in the housing body 11, thereby avoiding affecting the product appearance and saving the mold opening cost of the housing body 11.

[0032] In some embodiments, as Figure 2 shown, the housing body 11 includes a first side plate 111 and a second side plate 112 connected to the first side plate 111. The length of the first side plate 111 is greater than the length of the second side plate 112. The inverted buckle 12 is arranged on the inner wall of the first side plate 111.

[0033] In this embodiment, the side surface of the housing 11 is formed by sequentially connecting the first side plate 111 and the second side plate 112. The length of the first side plate 111 is greater than the length of the second side plate 112. The undercut 12 is arranged on the inner wall of the first side plate 111, and the bent portion 22 is arranged on the edge corresponding to the bracket main body 21 and the first side plate 111. Since the length of the first side plate 111 is greater than the length of the second side plate 112, the probability of deformation of the first side plate 111 is greater than the probability of deformation of the second side plate 112. The undercut 12 is arranged on the inner wall of the first side plate 111, and the screen pressing bracket 2 can be connected to the first side plate 111, thereby more efficiently preventing the first side plate 111 from deforming outward.

[0034] In some embodiments, Figure 2 As shown, the housing 11 includes two first side panels 111 and two second side panels 112 that are oppositely disposed. The undercut 12 is disposed on the inner wall of one of the first side panels 111 .

[0035] In this embodiment, the housing 11 is formed into a rectangle by two first side panels 111 and two second side panels 112 arranged opposite to each other, that is, the length of the first side panel 111 is greater than the length of the second side panel 112, and the two ends of each first side panel 111 are respectively connected to one end of the two second side panels 112, and the four side panels of the housing 11 can be integrally formed. The undercut 12 is only provided on the inner wall of one of the first side panels 111. When assembling the screen-pressing bracket 2 into the housing 11, the bracket main body 21 can be tilted first, and then the bent portion 22 of the screen-pressing bracket 2 is buckled into the undercut 12 of the housing 11, and then the bracket main body 21 is adjusted as a whole to be parallel to the display screen 3 in the housing 11, and then the first side panel 111 without the undercut 12 can be connected to the bracket main body 21 through a screw connection. Thus, compared with providing the undercuts 12 on both first side panels 111 , providing the undercuts 12 on only one first side panel 111 makes it more convenient to assemble the screen pressing bracket 2 and the housing 1 .

[0036] In other embodiments, the four side panels of the shell 11 may be formed separately and then assembled. In this case, undercuts 12 may be provided on both first side panels 111 , and bent portions 22 may be provided on both side edges corresponding to the bracket main body 21 and the first side panels 111 .

[0037] In some embodiments, Figure 2 As shown, the undercut 12 is arranged at the middle portion of the inner wall of the first side plate 111 .

[0038] In this embodiment, the undercut 12 is arranged in the middle of the inner wall of the first side plate 111, and the bent portion 22 is also arranged at a position of the bracket main body 21 corresponding to the undercut 12. The undercut 12 is arranged in the middle of the first side plate 111, so as to prevent the first side plate 111 from deforming outwards while setting as few undercuts 12 as possible. On the one hand, when the first side plate 111 deforms outwards, the probability of the middle area deforming outwards is the highest. Setting the undercut 12 in the middle of the inner wall of the first side plate 111 can effectively prevent the middle area of the first side plate 111 from deforming outwards; on the other hand, even if the areas of the first side plate 111 near its two ends have a tendency to deform outwards, setting the undercut 12 in the middle can prevent its deformation as much as possible, thereby achieving the most effective anti-deformation by setting the least undercuts 12.

[0039] In some embodiments, Figure 2 As shown, the number of the undercuts 12 is two, and the two undercuts 12 are spaced apart along the length direction of the first side plate 111; the bent portion 22 is in a convex shape so that the middle portion of the bent portion 22 is convex relative to the two ends of the bent portion 22, and the width of the middle portion of the bent portion 22 is adapted to the width of the interval between the two undercuts 12.

[0040] In this embodiment, two undercuts 12 are provided, and the two undercuts 12 are spaced apart along the length direction of the first side plate 111, that is, the undercuts 12 do not need to be provided along the entire length direction of the first side plate 111, so as to save material costs and minimize the space occupied in the housing 11, and the length of the bent portion 22 of the screen pressing bracket 2 corresponding to the undercut 12 corresponds to the total length of the two undercuts 12, that is, the bent portion 22 can be matched with the two undercuts 12 at the same time. Specifically, the bent portion 22 is in a convex shape so that the middle portion of the bent portion 22 is convex relative to the two ends of the bent portion 22, and the width of the middle portion of the bent portion 22 is adapted to the width of the interval between the two undercuts 12. When the bracket main body 21 is connected to the shell 11, the raised middle part of the bent portion 22 is inserted into the gap between the two undercuts 12, and the two ends of the bent portion 22 are matched with the two undercuts 12. Since the width of the gap between the two undercuts 12 matches the width of the middle part of the bent portion 22, the sides of the two undercuts 12 can limit the middle part of the bent portion 22, so that the two undercuts 12 limit the bent portion 22, that is, the bracket main body 21 will not move relative to the shell 11 in the length direction of the first side plate 111, so as to ensure the stability of the connection between the screen pressing bracket 2 and the shell 11. The two undercuts 12 are matched with the two ends of the bent portion 22, so that the bracket main body 21 pulls the shell 11 in the direction perpendicular to the first side plate 111, preventing the first side plate 111 from convexly deforming in the direction away from the bracket main body 21.

[0041] In some embodiments, Figure 3As shown, one side of the bracket main body 21 faces the display screen 3, the reverse buckle 12 is arranged on the other side of the bracket main body 21, and the bent portion 22 is bent away from the display screen 3.

[0042] In this embodiment, one side of the bracket main body 21 faces the display screen 3, and the reverse buckle 12 is arranged on the other side of the bracket main body 21, that is, the reverse buckle 12 is arranged on the side of the bracket main body 21 away from the display screen 3. The bent portion 22 is bent away from the display screen 3, that is, the bent portion 22 is arranged on the side of the bracket main body 21 away from the display screen 3, which is convenient for the bent portion 22 to cooperate with the reverse buckle 12. The bent portion 22 and the reverse buckle 12 are arranged on the side of the bracket main body 21 away from the display screen 3, so that it is not necessary to increase the distance between the bracket main body 21 and the display screen 3 to reserve space for the reverse buckle 12 and the bent portion 22, thereby ensuring the limiting function of the screen pressing bracket 2 on the display screen 3.

[0043] In some embodiments, as Figure 3 shown, one side of the bracket main body 21 facing the display screen 3 is closely attached to the display screen 3, so that the screen pressing bracket 2 can more effectively limit the display screen 3.

[0044] In some embodiments, referring together to Figure 2 and Figure 3 , the reverse buckle 12 includes a connecting portion 121 and a buckling portion 122. One end of the connecting portion 121 is connected to the inner side wall of the housing 11, the other end of the connecting portion 121 is connected to the buckling portion 122, and the distance between the inner side of the buckling portion 122 and the inner side wall of the housing 11 is adapted to the thickness of the bent portion 22.

[0045] Specifically, one end of the connecting portion 121 is connected to the inner wall of the first side plate 111 of the shell 11, and the connecting portion 121 is perpendicular to the inner wall of the first side plate 111, the other end of the connecting portion 121 is connected to one end of the snap-fit portion 122, and the snap-fit portion 122 is perpendicular to the connecting portion 121, and the other end of the snap-fit portion 122 faces the bracket main body 21, so that the undercut 12 has an opening facing the bracket main body 21. The distance between the inner side of the snap-fitting portion 122 and the inner side wall of the shell 11 is adapted to the thickness of the bent portion 22, that is, the opening width of the inverted buckle 12 toward the bracket main body 21 is adapted to the thickness of the bent portion 22. When the bent portion 22 cooperates with the inverted buckle 12, the bent portion 22 is inserted into the opening, and one end of the bent portion 22 facing the connecting portion 121 abuts against the inner side of the connecting portion 121, and the side of the bent portion 22 facing the snap-fitting portion 122 abuts against the inner side of the snap-fitting portion 122, thereby improving the stability of the cooperation between the bent portion 22 and the inverted buckle 12, so as to ensure that the screen-pressing bracket 2 more effectively limits the outward deformation of the shell 11. When the raised middle part of the bent portion 22 is inserted into the gap between the two inverted buckles 12, the two ends of the bent portion 22 cooperate with the snap-fitting parts 122 of the two inverted buckles 12, and the middle part of the bent portion 22 is limited by the opposite sides of the connecting parts 121 of the two inverted buckles 12, so that the two inverted buckles 12 limit the bent portion 22, so that the bracket main body 21 will not move relative to the shell 11 in the length direction of the first side plate 111, so as to ensure the stability of the connection between the screen pressing bracket 2 and the shell 11.

[0046] In some embodiments, refer to Figure 1 and Figure 3 The housing 1 further includes a display screen support 13, which is disposed on at least two inner side walls of the housing 1, and is disposed on a side of the display screen 3 away from the screen bracket, and the display screen 3 is disposed on the display screen support 13.

[0047] Specifically, the display screen support 13 is arranged on at least two inner walls of the shell 1 to facilitate supporting the display screen 3. The display screen support 13 is parallel to the plane with the largest area of the display screen 3, and the display screen support 13 is arranged on the side of the display screen 3 away from the bracket body 21, that is, the bracket body 21 and the display screen support 13 are respectively arranged on both sides of the display screen 3, and they work together to complete the limitation of the display screen 3 in the shell 11.

[0048] In some embodiments, the display support member 13 is disposed on two opposite inner sidewalls of the housing 1. Specifically, the display support member 13 can be disposed on the inner walls of the two first side plates 111. Since the length of the first side plate 111 is greater than the length of the second side plate 112, disposing the display support member 13 on the first side plate 111 can more stably support the display screen 3. In the length direction of the first side plate 111, two display support members 13 can be disposed at intervals, that is, the display support members 13 do not need to be disposed throughout the length direction of the first side plate 111, so as to save material costs.

[0049] It can be understood that in other embodiments, the display support members 13 can also be disposed on the four sidewalls of the housing 1, that is, the display support members 13 are disposed at intervals on the two first side plates 111 and the two second side plates 112.

[0050] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present invention.
