[0027] In order to make those skilled in the art better understand the present application scheme, the technical scheme in the present application embodiment will be clearly and completely described below in conjunction with the drawings in the present application embodiment. Obviously, the described embodiment is only a part of the present application embodiment, rather than all the embodiments. The components of the present application embodiment usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiment of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0028] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0029] With the continuous development of automobiles, the functions of vehicle-mounted systems have gradually become richer, and the demand for watching movies by passengers has also increased. Some in-car projection screens have been developed, but since the screen assembly is heavy and long and the space in the car is small, it is very inconvenient to install the screen in the car. When installing the screen, one worker needs to look up to hold the screen while another worker looks up to screw the screen, which results in low installation efficiency.

[0030] Therefore, in the embodiments of the present application, a vehicle-mounted display device and a vehicle are provided to solve or partially solve the above-mentioned problems.

[0031] This application proposes a vehicle-mounted display device, see Figure 1-Figure 3 ,in, Figure 1 A schematic structural diagram of the vehicle-mounted display device 100 is shown, wherein the scroll screen 14 is in an unfolded state. Figure 2 A schematic diagram of the assembly of the vehicle-mounted display device 100 is shown, wherein the scroll screen is in a retracted state. Figure 3 A schematic structural diagram of a pre-fixed assembly is shown, and the vehicle-mounted display device 100 includes.

[0032] The housing 11 is used to accommodate the scroll screen 14 .

[0033] The pre-fixing component 12 has a first end and a second end that are relatively arranged, the first end is fixedly connected to the shell 11, and the second end is a buckle portion 124, and the buckle portion 124 is used to cooperate with the buckle hole 131 of the roof beam 13 so that the buckle portion 124 and the buckle hole 131 can be detachably connected.

[0034] The housing 11 has a first mounting hole 111 , and the first mounting hole 111 is used to cooperate with the second mounting hole 132 of the roof cross beam 13 through a connecting piece, so that the housing 11 is fixed to the roof cross beam 13 .

[0035] It should be noted that the scroll screen 14 is made of flexible material.

[0036] In an exemplary embodiment, the scroll screen 14 is a screen for projection, and projection can be achieved by emitting corresponding light from a projector onto the screen.

[0037] In another exemplary embodiment, the scroll screen 14 is a display screen composed of multiple electronic display units, and the processor controls the multiple display units to display different colors, thereby realizing functions such as showing pictures and videos through the scroll screen 14.

[0038] It should be noted that the shell 11 is used to accommodate the scroll screen 14, that is, the internal cavity of the shell 11 can be used to accommodate the scroll screen 14, and the internal cavity of the shell 11 can also accommodate a driving component and a rotating mechanism. Specifically, the driving component is arranged in the shell 11 and connected to the rotating mechanism, and the rotating mechanism is connected to the scroll screen. The driving component is used to realize the unfolding or folding of the scroll screen by driving the rotating mechanism to rotate.

[0039] The buckle portion 124 may be an elastic buckle or a non-elastic buckle.

[0040] Exemplarily, when the buckle portion 124 is an elastic buckle, the buckle portion 124 can be elastically deformed by external force to enter the buckle hole 131. After entering the buckle hole 131, the buckle portion 124 returns to its original shape, and the buckle portion 124 and the buckle hole 131 form a mechanical lock, so that the buckle portion 124 and the buckle hole 131 can be detachably connected, which is convenient for replacing the vehicle-mounted display device without damaging the roof beam 13.

[0041] In another exemplary embodiment, the buckle portion is a non-elastic buckle. After the buckle portion is pushed into the buckle hole 131, the buckle portion and the buckle hole 131 are fixed by a locking structure to achieve mechanical locking of the buckle portion and the buckle hole 131. After the locking structure is released, the buckle portion and the buckle hole 131 can be separated, that is, a detachable connection between the buckle portion and the buckle hole 131 can be achieved.

[0042] The connecting piece may be a screw or a rivet.

[0043] In an optional embodiment, when installing the vehicle-mounted display device, a staff member first aligns the buckle portion 124 of the vehicle-mounted display device with the buckle hole 131 on the roof cross beam 13, and then pushes the buckle portion 124 into the corresponding buckle hole 131 with force until the buckle portion 124 reaches the preset position, and the buckle portion 124 and the buckle hole 131 are mechanically locked, and then the staff member releases his hands, and the vehicle-mounted display device and the roof cross beam 13 are pre-fixed. At this time, the first mounting hole 111 and the second mounting hole 132 are also in an aligned position, and the staff member then uses a screw to fix the first mounting hole 111 and the corresponding second mounting hole 132 together. The present application can pre-fix the housing 11 and the roof cross beam 13 through the pre-fixing component 12, and then fix the housing 11 and the roof cross beam 13. Only one staff member is required for installation, and the installation operation is simple and easy, which greatly improves the installation efficiency of the vehicle-mounted display device.

[0044] It should be noted that the size and position of the buckle portion 124, the size and position of the first mounting hole 111, the size and position of the buckle hole 131, and the size and position of the second mounting hole 132 can be pre-set so that when the buckle portion 124 on the vehicle display device cooperates with the buckle hole 131 on the roof cross beam 13, the first mounting hole 111 and the corresponding second mounting hole 132 can be aligned, that is, the purpose of pre-fixing is achieved through the pre-fixing component 12, which reduces the difficulty of installing the vehicle display device and improves the installation efficiency of the vehicle display device.

[0045] It should be noted that the shape of the buckle portion 124 matches the shape of the corresponding buckle hole 131 , and the shape of the first mounting hole 111 matches the shape of the corresponding second mounting hole 132 .

[0046] For further information, see Figure 2as well as Figure 3 The vehicle-mounted display device also includes: a positioning member 15.

[0047] The positioning member 15 is fixedly connected to the housing 11 . The shape of the positioning member 15 matches the shape of the positioning hole 133 of the roof crossbar 13 . The positioning hole 133 is used to limit the rotation of the positioning member 15 .

[0048] On the one hand, due to different installation habits of different workers, the buckle portion 124 may be subjected to uneven force during installation, resulting in irreversible deformation of the buckle portion 124, thereby affecting the alignment of the buckle portion 124 with the buckle hole 131. On the other hand, due to the large size of the body cross beam sheet metal, the deformation and tolerance are relatively large, which is also easy to affect the alignment of the buckle portion 124 with the buckle hole 131.

[0049] To this end, the vehicle display device of the present application also includes a positioning member 15, which is fixedly connected to the shell 11, and the shape of the positioning member 15 matches the shape of the positioning hole 133 of the roof beam 13, and the positioning hole 133 is used to limit the rotation of the positioning member 15.

[0050] In an exemplary embodiment, the positioning member 15 is fixedly connected to the shell 11. When the staff aligns the snap portion 124 with the snap hole 131, it is also necessary to align the positioning member 15 with the positioning hole 133 and push the positioning member 15 into the positioning hole 133. At the same time, the snap portion 124 is also pushed into the snap hole 131. The positioning member 15 is a rigid structure. When the positioning member 15 is matched with the positioning hole 133, the positioning hole 133 is used to limit the rotation of the positioning member 15, that is, the positioning member 15 and the positioning hole 133 are precisely aligned. For this reason, the present application achieves precise pre-fixation of the vehicle-mounted display device through the positioning member 15.

[0051] In an optional embodiment, please refer to 1. Figure 2 and Figure 6 The positioning member 15 is a conical structure, and the cross-sectional area of ​​the end of the positioning member 15 close to the shell 11 is larger than the cross-sectional area of ​​the end of the positioning member 15 away from the shell 11, so that the positioning member 15 can be pushed into the positioning hole 133 more quickly.

[0052] In an optional embodiment, the positioning member 15 has a guide structure, and the guide structure is used to limit the rotation of the positioning member 15 in the positioning hole 133.

[0053] For further information, see Figure 1 and Figure 2The shell 11 is a strip-shaped structure, and has first mounting holes 111 at both ends of the shell 11 respectively. A first surface 112 and a second surface 113 are oppositely arranged between the two ends of the shell 11, and a storage hole is opened on the second surface 113 as the entrance and exit of the scroll screen 14.

[0054] The first end of the pre-fixing component 12 is fixedly connected to the first surface 112 , and the positioning member 15 is fixedly connected to the first surface 112 .

[0055] The two ends of the shell 11 have first mounting holes 111 , respectively. By connecting the two ends of the shell 11 to the second mounting holes 132 of the roof cross beam 13 , the vehicle-mounted display device and the roof cross beam 13 can be made more stable.

[0056] Among them, the pre-fixing component 12 and the positioning component are fixedly connected to the first surface 112. During installation, the staff aligns the positioning piece 15 with the buckle part, and then pushes upward with force to push the shell 11 to the preset position, thereby pre-fixing the vehicle-mounted display device, and the installation is convenient and quick.

[0057] It should be noted that the number of the first mounting holes 111 at both ends of the shell 11 can be one or more, depending on actual needs and is not specifically limited here.

[0058] Furthermore, the number of the pre-fixing components 12 is at least 2, and the plurality of pre-fixing components 12 are distributed along a first direction, and the first direction is the length direction of the housing 11. Figure 2-Figure 4 as well as Figure 6-Figure 7 , the first direction can be the H direction.

[0059] The positioning member corresponds to at least one pre-fixed component and is arranged adjacently and spaced apart to assist in positioning the assembly of the pre-fixed component. It should be noted that the number of positioning members can be one or more, and the specific number can be determined according to actual needs and is not specifically limited here.

[0060] Furthermore, the height of the positioning member 15 relative to the first surface 112 is greater than the height of the pre-fixing assembly 12 relative to the first surface 112. When the staff installs the vehicle-mounted display device, the positioning member 15 can be quickly aligned with the positioning hole 133, and a part of the positioning member 15 is first pushed into the positioning hole 133. Then, since the positioning hole 133 restricts the rotation of the positioning member 15, and the buckle portion and the buckle hole 131 are also aligned at this time, the housing 11 can be pushed to the preset position more quickly to achieve pre-fixation.

[0061] For further information, see Figure 2-Figure 5 , Figure 4 Shows Figure 3 The schematic diagram of the cross-sectional structure of the pre-fixing component 12 in the figure, wherein the first end is a buckle seat 121, and the pre-fixing component 12 also includes a connecting portion 123, and the connecting portion 123 is fixedly connected to the buckle portion 124, and the buckle seat 121 has a locking groove, and the connecting portion 123 is locked in the locking groove.

[0062] Among them, the buckle seat 121 is fixedly installed on the first surface of the shell, the connecting part 123 is clamped in the clamping groove, and the connecting part 123 is connected to the buckle part 124, that is, the connection between the buckle part 124 and the first surface 112 of the shell is realized. When the buckle part 124 is clamped in the buckle hole 131, the shell and the roof beam are pre-fixed together, which provides convenience for subsequent screw installation.

[0063] For further information, see Figure 6 and Figure 7 , which shows a schematic diagram of the structure of the positioning member 15, the positioning member 15 is fixedly connected to the buckle seat 121, the first gap size 125 is the same as the second gap size 126, the first gap size 125 is the matching gap between the first connecting portion 1231 and the first clamping groove 1221 in the first direction, the second gap size 126 is the matching gap between the first connecting portion 1231 and the first clamping groove 1221 in the second direction, the second direction is parallel to the first surface, and perpendicular to the first direction. Please refer to Figure 3-Figure 4 as well as Figure 6-Figure 7 The second direction may be the F direction. It should be noted that the plane where the F direction and the H direction are located is parallel to the first surface 112 .

[0064] The first locking groove 1221 is a locking groove of the buckle seat 121 fixedly connected to the positioning member 15 , and the first connecting portion 1231 is a connecting portion matched with the first locking groove 1221 .

[0065] The positioning member 15 and the positioning hole are precisely matched. Since the pre-fixed components may have certain manufacturing tolerances, if there is no matching clearance between the connecting portion and the positioning slot, over-positioning may occur, making it difficult to simultaneously push the positioning member 15 and the buckle portion 124 into the positioning hole 133 and the buckle hole 131, resulting in failure in the installation of the vehicle-mounted display device. For this reason, in the embodiment of the present application, the positioning slot and the connecting portion have a matching clearance.

[0066] Please note that Figure 4 and Figure 7The matching gap is the gap between the outer wall of the connecting portion in the third direction and the inner wall of the positioning groove in the third direction, and the third direction is perpendicular to the first direction and the second direction respectively. Specifically, the size of the matching gap is the space distance between the outer wall of the connecting portion 123 and the inner wall of the positioning groove on the first straight line, and the first straight line is parallel to the first surface and passes through the axis of the connecting portion 123. Please refer to Figure 3 and Figure 6 , the third direction may be the G direction.

[0067] In an alternative embodiment, see Figure 7 The first positioning groove 1221 and the first connecting portion 1231 have a matching gap, and the first gap size 125 is the same as the second gap size 126. Under the condition that the positioning holes are aligned, it is convenient to align and install the buckle portion and the buckle hole, thereby improving the efficiency of pre-fixing the vehicle display device.

[0068] In an alternative embodiment, see Figure 4 The second positioning groove 1222 and the second connecting portion 1232 have a fitting clearance, the third gap dimension 127 is greater than the fourth gap dimension 128, the third gap dimension 127 is the fitting clearance between the second connecting portion 1232 and the second positioning groove 1222 in the first direction, and the fourth gap dimension 128 is the fitting clearance between the second connecting portion 1232 and the second positioning groove 1222 in the second direction.

[0069] The second locking groove 1222 is a locking groove of a buckle seat that is not fixedly connected to the positioning member, and the second connecting portion 1232 is a connecting portion that cooperates with the second locking groove 1222 .

[0070] When the staff pushes the shell toward the vehicle-mounted cross beam for pre-fixation, the third gap dimension 127 is greater than the fourth gap dimension 128, so that the buckle portion can be accurately aligned with the buckle hole of the roof cross beam in the second direction under the premise of convenient installation.

[0071] Furthermore, there is no matching gap between the second connecting portion 1232 and the second locking groove 1222 in the second direction. In other words, the fourth gap size is close to 0. During installation, it can be ensured that the buckle portion can be accurately aligned with the buckle hole of the roof beam in the second direction.

[0072] In an optional embodiment, the third gap size is greater than the fourth gap size, and the fourth gap size is 0, so that the fitting gap in the second direction is small for precise positioning, and the fitting gap in the first direction is relatively large, with a certain amount of room for movement, which facilitates the alignment and insertion of the buckle part and improves the installation efficiency of the vehicle-mounted display device.

[0073] In an alternative embodiment, see Figure 4 The cross section of the connecting portion 123 is circular, which facilitates the installation of the connecting portion 123 into the positioning groove.

[0074] In an optional embodiment, a sponge is provided between the connecting portion 123 and the buckle portion 124 , and the sponge is used to prevent the roof cross beam 13 from colliding with the pre-fixing assembly 12 and making noise.

[0075] In an optional embodiment, there is no matching gap between the connecting portion and the locking groove in the third direction, and the third direction is perpendicular to the first direction and the second direction respectively. When the locking portion is matched with the corresponding locking groove, the shell and the roof beam can be fixedly connected in the third direction. When the staff fixes the first mounting hole, there is no need to support the shell with extra force, making the installation easier.

[0076] For further information, see Figure 5 , which shows a schematic structural diagram of a part of the pre-fixed component, the buckle portion 124 includes an elastic protrusion 1241 and a limiting portion 1242, the limiting portion 1242 is located between the elastic protrusion 1241 and the connecting portion, and the maximum cross-sectional dimension of the limiting portion 1242 is smaller than the maximum cross-sectional dimension of the elastic protrusion 1241, so that the buckle portion 124 is clamped in the buckle hole.

[0077] Among them, when the buckle part 124 is not squeezed, the maximum cross-sectional dimension of the limiting part 1242 is smaller than the maximum cross-sectional dimension of the elastic protrusion 1241, and when the buckle part 124 is pushed into the buckle hole, the elastic protrusion 1241 is first squeezed and deformed to enter the buckle hole, and then when the buckle part 124 reaches the preset position, the elastic protrusion 1241 returns to its original shape, and the elastic protrusion 1241 forms a mechanical lock with the shape corresponding to the buckle hole, thereby realizing the detachable connection between the buckle part 124 and the buckle hole.

[0078] In an optional embodiment, the buckle portion is conical in shape, so that the buckle portion can be pushed into the buckle hole quickly and easily.

[0079] In an optional embodiment, the embodiment of the present application proposes a vehicle, including: a vehicle body, and the vehicle-mounted display device.
