Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, and in particular to an in-vehicle display screen, its assembly method, housing, and vehicle. Background Technology
[0002] With the development of the automotive industry, in-vehicle equipment is gradually becoming more intelligent and integrated. Among various advanced in-vehicle electronic devices, the in-vehicle display screen is a crucial component, serving as an integrated information display terminal. The in-vehicle display screen plays a key role in intelligent vehicle information interaction and display. An in-vehicle display screen typically consists of a housing and a display module mounted on the housing. However, to ensure the strength and reliability of the housing, the housing occupies a relatively large dimension in the thickness direction of the in-vehicle display screen, hindering the development of thinner and lighter in-vehicle display screens. Summary of the Invention
[0003] This application provides an in-vehicle display screen, its assembly method, housing, and vehicle, which helps to reduce the size of the in-vehicle display screen in the thickness direction.
[0004] In a first aspect, one embodiment of this application provides an in-vehicle display screen. The in-vehicle display screen includes a housing and a display module. The housing includes a separately configured mid-frame and a rear shell. The sidewalls of the mid-frame extend along the thickness direction of the in-vehicle display screen, and a portion of the sidewalls is exposed outside the in-vehicle display screen. The outer surface of the mid-frame has a recess extending circumferentially along the mid-frame, and a portion of the rear shell is received within the recess. The rear shell is fixedly connected to the mid-frame. At least a portion of the display module is received within the mid-frame, and the display module and the rear shell are stacked along the thickness direction.
[0005] The vehicle display screen provided in this application has a housing comprising a split middle frame and a rear shell, with a portion of the rear shell housed in a recess. The rear shell reuses the dimensions of the middle frame in the thickness direction of the vehicle display screen, meaning that a portion of the rear shell overlaps with a portion of the side wall. This helps to reduce the size of the housing in the thickness direction of the vehicle display screen while ensuring the strength of the housing, thereby achieving an overall visual thinning effect of the display screen and thus contributing to the development of thinner and lighter vehicle display screens.
[0006] According to the first aspect, in one possible implementation, the middle frame further includes a bottom wall connected to the side wall, the bottom wall and the side wall together forming a receiving space for accommodating the display module, the bottom wall being located between the rear shell and the display module in the thickness direction, the bottom wall having a through hole communicating with the receiving space, and a recess extending from the side wall to the bottom wall.
[0007] In this possible implementation, the bottom wall can enhance the strength of the mid-frame and reduce the possibility of mid-frame cracking. The bottom wall is located between the back shell and the display module in the thickness direction, and the bottom wall is used to support the display module in the thickness direction, thereby improving the stability of the mid-frame supporting the display module.
[0008] According to the first aspect, in one possible implementation, at least a portion of the outer surface of the rear shell on the side opposite to the receiving space contacts at least a portion of the outer surface of the side wall on the side opposite to the receiving space. In this way, the outer surface of the rear shell and the outer surface of the side wall are spliced together to form a more complete outer surface, reducing the gap between the rear shell and the side wall and reducing the possibility of dust and other debris entering the interior of the vehicle display screen.
[0009] According to the first aspect, in one possible implementation, in the cross-section of the vehicle display screen parallel to the thickness direction, the sidewall facing away from the receiving space includes a first arc segment, and the rear shell facing away from the display module includes a second arc segment. The first arc segment and the second arc segment are joined together. Compared to setting the outer surface of the sidewall as a planar structure parallel to the thickness direction of the vehicle display screen, the extension length of the first arc segment is longer, which is beneficial to enhancing the strength of the mid-frame. Since the first arc segment and the second arc segment are joined together, a thinning effect can be achieved from the user's visual perspective, improving the user experience.
[0010] According to the first aspect, in one possible implementation, the inner wall of the recess fits against the side of the rear shell facing the recess, increasing the contact area between the middle frame and the rear shell and improving the connection stability between the middle frame and the rear shell.
[0011] According to the first aspect, in one possible implementation, the inner wall of the recess is provided with a connection hole communicating with the receiving space, and the rear shell includes a hot-melt column, which passes through the connection hole, and a portion of the hot-melt column is fixedly connected to the inner wall of the middle frame.
[0012] In this possible implementation, when assembling the middle frame and the rear shell together, a heat-fused pillar is first inserted through the connection hole, and then heated. At least a portion of the heat-fused pillar melts and is fixedly connected to the inner wall of the receiving space. Achieving a non-detachable fixed connection between the rear shell and the middle frame through heat fusion improves the connection stability between the rear shell and the middle frame, enhances the strength of the shell, and reduces the possibility of cracking of the middle frame.
[0013] According to the first aspect, in one possible implementation, a positioning boss protrudes from the inner wall of the recess, and a connecting hole penetrates the positioning boss. A positioning groove is formed on the side of the rear shell facing the display module, a hot-melt column protrudes from the bottom wall of the positioning groove, and a portion of the positioning boss is received within the positioning groove.
[0014] In this possible implementation, when the rear shell and the middle frame need to be assembled together, the positioning boss and the positioning groove are used to position the hot melt pillar through the connection hole, which helps to improve the assembly convenience and assembly efficiency between the rear shell and the middle frame.
[0015] According to the first aspect, in one possible implementation, there are multiple connecting holes arranged circumferentially along the recess, and multiple hot melt pillars, with the number of hot melt pillars corresponding one-to-one with the number of connecting holes.
[0016] In this possible implementation, multiple connecting holes and hot-melt pillars are provided along the circumference of the recess to further improve the connection strength and stability between the rear shell and the middle frame, which helps to further reduce the possibility of cracking of the middle frame.
[0017] According to the first aspect, in one possible implementation, multiple hot-melt pillars are arranged at equal intervals along the circumference of the rear shell, so that the multiple hot-melt pillars are evenly distributed in the circumference of the rear shell, which is beneficial to the uniform stress on the middle frame in the circumference and reduces the possibility of cracking of the middle frame.
[0018] According to the first aspect, in one possible implementation, along the circumferential direction of the recess, the vehicle display screen is further provided with a first adhesive layer between two adjacent hot melt pillars, and the first adhesive layer is bonded between the rear shell and the inner wall of the recess in the thickness direction of the vehicle display screen.
[0019] In this possible implementation, a first adhesive layer is provided along the circumference of the recess, utilizing the space between two adjacent hot-melt pillars. This improves the connection stability between the middle frame and the rear shell, reduces the gap between the middle frame and the rear shell in the thickness direction of the vehicle display screen, and enhances the sealing performance between the middle frame and the rear shell, thus reducing the possibility of moisture and other debris entering the vehicle display screen. Furthermore, the first adhesive layer effectively absorbs abnormal noises caused by shaking or other factors affecting the vehicle display screen.
[0020] According to the first aspect, in one possible implementation, the rear shell also includes reinforcing ribs protruding from the side of the rear shell facing the display module, which helps to improve the strength and rigidity of the rear shell.
[0021] According to the first aspect, in one possible implementation, the rear cover is further provided with a mounting port, the vehicle display screen also includes a circuit board and a bracket, the circuit board is located between the display module and the bracket in the thickness direction, the display module is electrically connected to the circuit board, at least one of the rear cover and the middle frame is fixedly connected to the display module, the bracket is received in the mounting port, the bracket is used to install on the vehicle body, and the bracket, circuit board and display module are fixedly connected.
[0022] In this possible implementation, the bracket facilitates the assembly of the vehicle display screen with the vehicle body.
[0023] According to the first aspect, in one possible implementation, the display module has a fixed protrusion on the side facing the circuit board, the circuit board has a first through hole, the bracket has a second through hole, and the vehicle display screen also includes a fastener, which passes through the second through hole, the first through hole, and the fixed protrusion, and the fastener is fixedly connected to the fixed protrusion.
[0024] In this possible implementation, fasteners are used to fix the display module, circuit board and bracket together, thereby improving the connection strength and stability between the display module, circuit board and bracket and reducing the possibility of the display module, circuit board and bracket becoming loose.
[0025] According to the first aspect, in one possible implementation, the orthographic projection of the circuit board on the rear housing is located within the mounting opening, the bracket blocks the mounting opening, and the length of the circuit board is less than the length of the mounting hole.
[0026] In related technologies, the length of the circuit board is approximately the same as the length of the mounting hole. In this possible implementation, the length of the circuit board is less than the length of the mounting hole. This reduces the amount of material used in the circuit board, thus lowering the manufacturing cost of the automotive display screen, while maintaining the same circuit board length. Furthermore, the size of the automotive display screen can be smaller with the same circuit board length, which helps to reduce the space occupied by the display screen.
[0027] According to the first aspect, in one possible implementation, the vehicle display screen further includes a second adhesive layer, and at least one of the rear shell and the middle frame is fixedly connected to the display module through the second adhesive layer.
[0028] According to the first aspect, in one possible implementation, the vehicle display screen also includes a protective cover, which is disposed on the side of the display module away from the rear cover, and the protective cover is used to protect the display module and reduce the possibility of damage to the display module.
[0029] According to the first aspect, in one possible implementation, the in-vehicle display screen is a center console display screen.
[0030] Secondly, according to one embodiment of this application, a vehicle is also provided, the vehicle including a vehicle body and an in-vehicle display screen according to the first aspect, the in-vehicle display screen being disposed on the vehicle body.
[0031] Thirdly, one embodiment of this application also provides a method for assembling a vehicle-mounted display screen, the assembly method comprising:
[0032] The middle frame and the rear shell are assembled into a housing. The side wall of the middle frame extends along the thickness direction of the vehicle display screen, and part of the side wall is exposed outside the housing. The outer surface of the middle frame is provided with a recess extending circumferentially along the middle frame. Part of the rear shell is housed in the recess and is fixedly connected to the middle frame.
[0033] The display module is at least partially housed in the middle frame, and the display module and the rear shell are stacked along the thickness direction of the vehicle display screen.
[0034] According to the third aspect, in one possible implementation, assembling the mid-frame and rear shell into a housing includes:
[0035] The hot-melt pillar of the rear shell is inserted through the connection hole of the middle frame, and part of the hot-melt pillar is located inside the middle frame;
[0036] Heating to a preset temperature to melt at least a portion of the hot melt column;
[0037] After cooling, the hot-melt column is fixed to the inner surface of the middle frame and / or the inner wall of the connecting hole.
[0038] According to the third aspect, in one possible implementation, the hot-melt pillar of the rear shell is inserted in front of the connecting hole of the middle frame, and the assembly of the middle frame and the rear shell into a housing further includes: providing a first adhesive layer between two adjacent hot-melt pillars, and bonding the first adhesive layer between the rear shell and the middle frame.
[0039] Fourthly, this application also provides a housing, which includes a separate middle frame and a rear shell. The middle frame is used to house at least a portion of the display module. The sidewalls of the middle frame extend along the thickness direction of the display screen. A portion of the sidewalls is exposed outside the rear shell. The outer surface of the middle frame is provided with a recess extending circumferentially along the middle frame. A portion of the rear shell is housed in the recess, and the rear shell is fixedly connected to the middle frame.
[0040] The housing provided in this application includes a split middle frame and a rear shell. When the rear shell is applied to a device with a display module, a portion of the rear shell is housed within a recess. The rear shell reuses the dimensions of the middle frame in the thickness direction of the display module, meaning that a portion of the rear shell overlaps with a portion of the side wall. This helps to reduce the size of the housing in the thickness direction of the display module while ensuring the strength of the housing, achieving an overall visual thinning of the housing, thereby contributing to the development of thinner and lighter devices with display modules.

Detailed Implementation
[0057] Please see Figure 1 One embodiment of this application provides a vehicle 1, which includes a vehicle body 2 and a display screen 3 disposed on the vehicle body 2. Figure 1The illustration shows that the center console and seats of vehicle 1 are equipped with display screens 3. In this application, display screen 3 refers to an in-vehicle display screen. The following description uses a center console display screen 3 located on the center console as an example. Vehicle 1 can be an electric vehicle, a gasoline vehicle, or a hybrid vehicle, such as a pure electric vehicle, a range-extended electric vehicle, a hybrid electric vehicle, a fuel cell vehicle, or a new energy vehicle; this application does not specifically limit this type of vehicle.
[0058] Display screens typically consist of a unibody housing with a display module mounted within it. However, since displays need to be installed in vehicle bodies, their components require high reliability. To ensure the strength and reliability of the housing, the housing occupies a relatively large dimension in the thickness direction of the display screen, hindering the development of thinner and lighter displays.
[0059] Based on this, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 This application provides a display screen 3 in one embodiment, which facilitates a reduction in the thickness dimension of the display screen 3. The display screen 3 includes a housing 20 and a display module 30. Please refer to the following reference. Figure 4 , Figure 5 , Figure 6 and Figure 7 The housing 20 includes a separate middle frame 21 and a rear housing 23. The side wall 211 of the middle frame 21 extends along the thickness direction of the vehicle display screen, and part of the side wall 211 is exposed outside the display screen 3. The outer surface of the middle frame 21 has a recess 213 extending circumferentially along the middle frame 21. Please refer to the reference. Figure 7 and Figure 8 A portion of the rear shell 23 is housed within the recess 213, and the rear shell 23 is fixedly connected to the middle frame 21. At least a portion of the display module 30 is housed within the middle frame 21, and the display module 30 and the rear shell 23 are stacked along the thickness direction. The display module 30 is used to display images.
[0060] The display screen 3 provided in this application has a housing 20 including a split middle frame 21 and a rear shell 23. Part of the rear shell 23 is housed in a recess 213. The rear shell 23 reuses the size of the middle frame 21 in the thickness direction of the display screen 3. That is, part of the rear shell 23 overlaps with part of the side wall 211. This is beneficial to reduce the size occupied by the housing 20 in the thickness direction of the display screen 3 while ensuring the strength of the housing 20, thereby achieving an overall visual thinning effect of the display screen 3 and thus contributing to the development of a thinner and lighter display screen 3.
[0061] This application does not limit the display screen 3 to an in-vehicle display screen. The display screen 3 can also be used in other fields, such as electronic devices with display modules 30, etc.
[0062] The display screen 3 also includes a circuit board 40 and a bracket 70. The circuit board 40 is located between the display module 30 and the bracket 70 in the thickness direction. The display module 30 is electrically connected to the circuit board 40. At least one of the rear shell 23 and the middle frame 21 is fixedly connected to the display module 30. The bracket 70 is received in the mounting port 233 and is used for mounting on the vehicle body 2. The bracket 70, circuit board 40, and display module 30 are fixedly connected. The bracket 70 facilitates the assembly of the display screen 3 and the vehicle body 2. In this embodiment, please refer again... Figure 6 The circuit board 40, projected onto the rear housing 23, lies within the mounting opening 233. The bracket 70 obstructs the mounting opening 233, and the length of the circuit board 40 is less than the length of the mounting hole. In related technologies, the length of the circuit board is approximately the same as the length of the mounting hole. In this possible implementation, the length of the circuit board is less than the length of the mounting opening. With the same display screen 3 size, this reduces the material used in the circuit board 40, lowering the manufacturing cost of the display screen 3. With the same circuit board 40 length, the display screen 3 can be smaller, reducing the space occupied by the display screen 3. It is understood that this application does not limit the length of the circuit board 40; the length of the circuit board 40 can be greater than or equal to the length of the mounting opening 233.
[0063] At least a portion of the display module 30 is housed within the middle frame 21. The middle frame 21 encloses a housing space. The outer surface of the middle frame 21 is the surface facing away from the housing space of the middle frame 21. The inner surface of the middle frame 21 is the surface of the housing space of the middle frame 21.
[0064] In this embodiment, please refer to the following: Figure 7 and Figure 9 The middle frame 21 also includes a bottom wall 212 connected to the side wall 211. The bottom wall 212 and the side wall 211 together form a receiving space for accommodating the display module 30. The bottom wall 212 is located between the rear shell 23 and the display module 30 in the thickness direction. The bottom wall 212 has a through hole 2121 communicating with the receiving space, and a recess 213 extends from the side wall 211 to the bottom wall 212. The bottom wall 212 can enhance the strength of the middle frame 21, thereby reducing the possibility of cracking of the middle frame 21. The bottom wall 212 is located between the rear shell 23 and the display module 30 in the thickness direction, and the bottom wall 212 is used to support the display module 30 in the thickness direction, thereby improving the stability of the middle frame 21 in supporting the display module 30.
[0065] The middle frame 21 can be made of plastic to reduce its weight. This application does not limit the material of the middle frame 21. The material of the middle frame 21 can also be metal or non-metal. In some possible implementations, the material of the middle frame 21 may include metals, such as stainless steel, aluminum alloy, titanium alloy, magnesium alloy, etc. The middle frame 21 can be manufactured through processes such as two-color injection molding, two-color spraying, spraying on the substrate, electroplating on the substrate, screen printing or pad printing on the substrate.
[0066] Please see Figure 7 and Figure 8 The inner wall of the recess 213 is provided with a connecting hole 2131 for connecting with the rear shell 23, thereby assembling the rear shell 23 and the middle frame 21 together. A positioning boss 2133 protrudes from the inner wall of the recess 213, and the connecting hole 2131 passes through the positioning boss 2133. The positioning boss 2133 is used to cooperate with the rear shell 23 to provide positioning when the rear shell 23 and the middle frame 21 are assembled together, thereby improving the ease and efficiency of assembly. This application does not limit the shape of the connecting hole 2131; for example, the connecting hole 2131 can be a circular hole, an oblong hole, a square hole, or other regular or irregular shaped holes.
[0067] The inner wall of the recess 213 fits against the side of the rear shell 23 facing the recess 213, increasing the contact area between the middle frame 21 and the rear shell 23 and improving the connection stability between the middle frame 21 and the rear shell 23.
[0068] In this embodiment, at least a portion of the outer surface of the rear shell 23 facing away from the receiving space contacts at least a portion of the outer surface of the side wall 211 facing away from the receiving space. In this way, the outer surface of the rear shell 23 and the outer surface of the side wall 211 are spliced together to form a more complete outer surface, reducing the gap between the rear shell 23 and the side wall 211 and reducing the possibility of dust and other debris entering the interior of the display screen 3.
[0069] In some embodiments, the outer surface of the rear shell 23 facing away from the receiving space may not be in contact with the outer surface of the side wall 211 facing away from the receiving space, and there may be a gap between the outer surface of the rear shell 23 facing away from the receiving space and the outer surface of the side wall 211 facing away from the receiving space.
[0070] In this embodiment, in the cross-section where the display screen 3 is parallel to the thickness direction, please refer again. Figure 7 The sidewall 211 facing away from the receiving space includes a first arc segment 2111, and the rear shell 23 facing away from the display module 30 includes a second arc segment 235. This allows for a longer extension of the first arc segment 2111 compared to making the outer surface of the sidewall 211 a planar structure parallel to the thickness direction of the display screen 3, thus enhancing the strength of the mid-frame 21. Since the first arc segment 2111 and the second arc segment 235 are joined together, a thinning effect can be achieved visually, improving the user experience. This application does not limit the structure of the sidewall 211 facing away from the receiving space; for example, the sidewall 211 facing away from the receiving space may include a plane and / or a curved surface. This application does not limit the structure of the rear shell 23 facing away from the display module 30; for example, the side of the rear shell 23 facing away from the display module 30 and the receiving space may include a plane and / or a curved surface.
[0071] Please refer to the following: Figure 7 and Figure 10 The rear shell 23 includes a hot-melt post 231 protruding from the side of the rear shell 23 facing the display module 30. The hot-melt post 231 is used to connect with the middle frame 21. The hot-melt post 231 passes through the connection hole 2131, and a portion of the hot-melt post 231 is fixedly connected to the inner wall of the connection hole 2131 and / or the inner wall of the receiving space to fix the rear shell 23 and the middle frame 21 together.
[0072] When assembling the middle frame 21 and the rear shell 23 together, first insert the hot-melt post 231 through the connecting hole 2131, such as... Figure 11 and Figure 12 The heat-fused column 231 shown is the heat-fused column before being heated. Upon heating, at least a portion of the heat-fused column 231 melts and is fixedly connected to the inner wall of the connecting hole 2131 and / or the inner wall of the receiving space. Achieving a fixed connection between the rear shell 23 and the middle frame 21 through heat fusion improves the connection stability between the rear shell 23 and the middle frame 21, enhances the strength of the shell 20, and reduces the possibility of cracking in the middle frame 21.
[0073] The thermoplastic column 231 is made of thermoplastic material. Thermoplastic materials are a class of materials that soften or melt when heated and re-solidify after cooling, and have the characteristics of being reprocessable and recyclable.
[0074] A positioning groove 232 is formed on the side of the back cover 23 facing the display module 30. The hot melt pillar 231 protrudes from the bottom wall of the positioning groove 232, and part of the positioning boss 2133 is received in the positioning groove 232. When the back cover 23 and the middle frame 21 need to be assembled together, the positioning boss 2133 and the positioning groove 232 are used to position the hot melt pillar 231 as it passes through the connecting hole 2131, which helps to improve the assembly convenience between the back cover 23 and the middle frame 21.
[0075] In this embodiment, there are multiple connecting holes 2131 arranged circumferentially along the recess 213, and multiple hot-melt pillars 231, with the number of pillars corresponding one-to-one with the number of connecting holes 2131. The arrangement of multiple connecting holes 2131 and multiple hot-melt pillars 231 along the circumferential direction of the recess 213 further improves the connection strength and stability between the rear shell 23 and the middle frame 21. The multiple hot-melt pillars 231 are evenly spaced along the circumferential direction of the rear shell 23, ensuring uniform distribution and promoting even stress distribution on the middle frame 21, thus reducing the likelihood of cracking. This application does not limit the arrangement of the multiple hot-melt pillars 231 to unequal intervals along the circumferential direction of the rear shell 23; that is, the multiple hot-melt pillars 231 can be unevenly distributed along the circumferential direction of the rear shell 23. This application does not limit the number of connecting holes 2131, nor does it limit the number of hot melt pillars 231. For example, the number of connecting holes 2131 can be one, and the number of hot melt pillars 231 can be one.
[0076] The back cover 23 can be made of plastic to reduce its weight. This application does not limit the material of the back cover 23. The material of the back cover 23 can also be metal or non-metal. In some possible implementations, the material of the back cover 23 can include metals, such as stainless steel, aluminum alloy, titanium alloy, magnesium alloy, etc. The back cover 23 can be manufactured through processes such as two-color injection molding, two-color spraying, coating on the substrate, electroplating on the substrate, screen printing or pad printing on the substrate. This application does not limit the color of the outer surface of the middle frame 21. For example, the color of the outer surface of the middle frame 21 can be bright silver, bright black, etc., to further enhance the thinning effect visually to the user.
[0077] This application does not limit the connection method between the rear shell 23 and the middle frame 21. For example, the hot melt pillar 231 can be omitted, and the rear shell 23 and the middle frame 21 can be connected together by snap-fit, riveting, adhesive or other means.
[0078] The rear cover 23 is also provided with a mounting opening 233. In this embodiment, a portion of the rear cover 23 protrudes in the direction away from the display module 30 and forms a mounting opening 233 to facilitate the assembly of the rear cover 23 with the vehicle body 2.
[0079] The rear housing 23 also includes a reinforcing rib 237 protruding from the rear housing 23 toward the display module 30 (e.g., Figure 10 As shown in the figure, this is beneficial to improving the strength and stiffness of the rear shell 23.
