Description

Technical Field

[0001] This application relates to the field of projection screen technology, and in particular to projection screen devices. Background Technology

[0002] As the functions of in-vehicle systems become increasingly diverse, in-vehicle projection equipment has emerged, among which electrically controlled lifting screens are an indispensable component.

[0003] In related technologies, after the vehicle-mounted screen is installed on the vehicle, there is a fitting gap and a fitting step difference between the screen cover and the roof. Under normal circumstances, there will be compression between the cover and the roof.

[0004] However, compression may cause the cover plate to deform significantly, which in turn makes the fit gap and gap between the cover plate and the roof uneven, thereby reducing the aesthetics of the vehicle screen and failing to meet the user's needs. Utility Model Content

[0005] The main technical problem addressed by this application is to provide a projection screen device that can solve the problem that related technologies cannot effectively improve cover plate deformation.

[0006] To solve the above-mentioned technical problems, the first technical solution adopted in this application is to provide a projection screen device, including a first cover plate and a second cover plate disposed opposite to each other, and a screen assembly and a lifting assembly located between the first cover plate and the second cover plate; a plurality of connectors are provided on both sides of the first cover plate extending along a first direction, and the first cover plate is connected to a fixed housing through the plurality of connectors; wherein, a first reinforcing member is provided between two adjacent connectors, and the two ends of the first reinforcing member extending along the first direction are respectively connected to the sides of the two adjacent connectors extending along a second direction; the second direction is perpendicular to the first direction.

[0007] The first reinforcing member is provided with at least one second reinforcing member; wherein the length extension direction of the second reinforcing member is parallel to the second direction.

[0008] The first reinforcing member is provided with a plurality of second reinforcing members, which are located at both ends and the middle of the first reinforcing member extending along the first direction.

[0009] The first reinforcing member includes a reinforcing member body, and the two ends of the reinforcing member body extending along the first direction are respectively connected to the sides of two adjacent connecting members extending along the second direction.

[0010] The first reinforcing member is provided with I-shaped connectors at both ends and the middle of its extension along the first direction. The I-shaped connector includes a first plate, a second plate, and a first connecting part connecting the first plate and the second plate, all extending along the first direction. The first plate is the main body of the reinforcing member, and the first connecting part is located in the middle of the second plate extending along the first direction.

[0011] The outer edges of the two second plates located at both ends of the first reinforcing member are respectively connected to the side edges of the two adjacent connecting members extending along the second direction.

[0012] The outer edges of the two second plates located at both ends of the first reinforcing member are provided with second connecting parts, which connect to the main body of the reinforcing member.

[0013] Each second plate is provided with at least one second reinforcing member, and the reinforcing member body is provided with at least one second reinforcing member.

[0014] The connector includes a through-hole buckle, and the fixed housing has multiple protrusions on both sides extending in the first direction. Each protrusion is used to insert into the corresponding through-hole buckle so that the first cover plate is engaged with the fixed housing.

[0015] The first cover plate has two positioning holes on both sides extending along the third direction, and the fixed housing has two fixing holes on both sides extending along the third direction.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. The singular forms “a,” “said,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless otherwise clearly indicated above. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0026] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0027] It should be understood that the terms "comprising," "including," or any other variations used herein are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] In related technologies, after the vehicle-mounted screen is installed on the vehicle, there is a fitting gap and a fitting step difference between the screen cover and the roof. Under normal circumstances, there will be compression between the cover and the roof.

[0029] However, compression may cause the cover plate to deform significantly, which in turn makes the fit gap and gap between the cover plate and the roof uneven, thereby reducing the aesthetics of the vehicle screen and failing to meet the user's needs.

[0030] Based on the above, this application provides a projection screen device that can solve the problem that related technologies cannot effectively improve cover plate deformation.

[0031] The projection screen device provided in this application includes a first cover plate and a second cover plate arranged opposite to each other, and a screen assembly and a lifting assembly located between the first cover plate and the second cover plate. Multiple connectors are provided on both sides of the first cover plate extending along a first direction, and the first cover plate is connected to a fixed housing through the multiple connectors. A first reinforcing member is provided between two adjacent connectors, and the two ends of the first reinforcing member extending along the first direction are respectively connected to the sides of the two adjacent connectors extending along a second direction. The second direction is perpendicular to the first direction. By providing multiple connectors on both sides of the first cover plate extending along the first direction, and providing a first reinforcing member between two adjacent connectors, and by connecting the two ends of the first reinforcing member extending along the first direction to the sides of the two adjacent connectors extending along the second direction, the multiple connectors can be connected into a whole through the multiple first reinforcing members. This improves the overall rigidity and structural strength of the first cover plate, as well as the stability of the assembly between the first cover plate and the fixed housing, thereby effectively reducing the deformation of the first cover plate. This results in a uniform fit gap and fit discontinuity between the first cover plate and the top of the external device, improving the aesthetics of the vehicle-mounted screen and thus meeting the user's needs.

[0032] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the assembly structure of the projection screen device of this application. Figure 2yes Figure 1 A schematic diagram of the exploded structure of a projection screen device.

[0034] In this embodiment, the projection screen device 100 includes a first cover plate 10 and a second cover plate 20 disposed opposite to each other, and a screen assembly 30 and a lifting assembly 40 located between the first cover plate 10 and the second cover plate 20. The first cover plate 10 is connected to the fixed housing 60 to fix the projection screen device 100 to the top of the external device.

[0035] Among them, the first cover plate 10 is equivalent to the upper cover, the second cover plate 20 is equivalent to the lower cover, and the second cover plate 20 is a movable cover plate.

[0036] The curtain assembly 30 includes a curtain body 31 and a curtain motor assembly 32. The first side of the curtain body 31 is connected to the first cover plate 10, and the second side of the curtain body 31 is connected to the second cover plate 20. The first side and the second side are arranged opposite to each other.

[0037] The lifting assembly 40 includes a first arm 41 and a second arm 42. The first arm 41 is controlled by a first worm motor 43, and the second arm 42 is controlled by a second worm motor 44.

[0038] In some embodiments, the projection screen device 100 also includes a control board 101 and a position sensor 102.

[0039] In some embodiments, the fixed housing 60 is used to secure to an external device, including a mobile vehicle.

[0040] Understandably, by fixing the fixed housing 60 to the top of the mobile vehicle with rigid connectors such as bolts or screws, the projection screen device 100 can maintain the same vibration frequency as the mobile vehicle. Therefore, when the user watches the projection inside the mobile vehicle, there will be no uncomfortable viewing experience due to the different vibration frequencies of the vehicle and the screen body 31.

[0041] Please refer to the following: Figure 3 and Figure 4 , Figure 3 yes Figure 1 Front view of the connection between the first cover plate and the fixed housing. Figure 4 yes Figure 1 Axonometric view of the connection between the first cover plate and the fixed housing.

[0042] In this embodiment, a plurality of connectors 50 are provided on both sides of the first cover plate 10 extending along the first direction x, and the first cover plate 10 is connected to the fixed housing 60 through the plurality of connectors 50. Among them, a first reinforcing member 70 is provided between two adjacent connectors 50, and the two ends of the first reinforcing member 70 extending along the first direction x are respectively connected to the sides of the two adjacent connectors 50 extending along the second direction y, which is perpendicular to the first direction x.

[0043] Wherein, the first direction x is the horizontal direction of the screen body 31, that is, the left-right direction of the projected image. The second direction is the vertical direction of the screen body 31, that is, the up-down direction of the projected image.

[0044] In this embodiment, the connector 50 includes a through-hole buckle, and the fixed housing 60 has a plurality of protrusions 61 on both sides extending along the first direction x. Each protrusion is used to insert into the corresponding through-hole buckle so that the first cover plate 10 is engaged with the fixed housing 60.

[0045] In this embodiment, the first cover plate 10 has two positioning holes 11 on each side extending along the third direction z, and the fixed housing 60 has two fixing holes (not shown) on each side extending along the third direction z. The positioning holes 11 and the fixing holes are used to cooperate with a fastener (not shown) to fix the first cover plate 10 and the fixed housing 60. The third direction z is perpendicular to the first direction x and the second direction y.

[0046] Wherein, the third direction z is the direction perpendicular to the plane where the curtain body 31 is located.

[0047] In some implementations, the fastener is a screw.

[0048] Understandably, the two sides extending along the first direction x of the first cover plate 10 are the long sides of the first cover plate 10, and the two sides extending along the third direction x of the first cover plate 10 are the short sides of the first cover plate 10. By forming a snap-fit ​​connection between the long side of the first cover plate 10 and the fixed housing 60, and by forming a screw connection between the short side of the first cover plate 10 and the fixed housing 60, the bending of the first cover plate 10 can be effectively prevented, thereby improving the deformation of the first cover plate 10. Furthermore, the snap-fit ​​connection and screw connection can also simplify the assembly process and reduce the assembly difficulty, thereby improving production efficiency.

[0049] In this embodiment, by providing a plurality of connectors 50 on both sides of the first cover plate 10 extending along the first direction x, and providing a first reinforcing member 70 between two adjacent connectors 50, and by connecting the two ends of the first reinforcing member 70 extending along the first direction x to the sides of the two adjacent connectors 50 extending along the second direction y respectively, the plurality of connectors 50 can be connected into a whole by the plurality of first reinforcing members 70.

[0050] Understandably, by connecting multiple connectors 50 into a whole through multiple first reinforcing members 70, the overall rigidity and structural strength of the first cover plate 10 can be improved, as well as the clamping force after the first cover plate 10 and the fixed housing 60 are assembled, so as to improve the stability of the assembly and thus effectively improve the deformation of the first cover plate 10.

[0051] Furthermore, since the first cover plate 10 is a hollow structure, it will undergo linear expansion or contraction at high temperatures (e.g., 40°C) or low temperatures (e.g., -40°C). By setting multiple first reinforcing members 70 to connect multiple connecting members 50 into a whole, the linear expansion or contraction of the first cover plate 10 at high or low temperatures can be effectively reduced, thereby further improving the deformation of the first cover plate 10. This makes the fit gap and fit discontinuity between the first cover plate 10 and the top of the external device uniform, thereby improving the aesthetics of the curtain body 31 and meeting the user's usage needs.

[0052] Furthermore, by effectively reducing the linear expansion or contraction of the first cover plate 10 at high or low temperatures, it is also possible to reduce the jamming caused by insufficient clearance in the motion mechanism (e.g., the screen motor assembly 32 or the lifting assembly 40) due to linear expansion or contraction, thereby improving the stability and reliability of the projection screen device 100.

[0053] Please refer to the following: Figure 5 and Figure 6 , Figure 5 yes Figure 1 A schematic diagram of the structure of the first cover plate. Figure 6 yes Figure 5 A magnified structural diagram of area A in the middle.

[0054] In this embodiment, at least one second reinforcing member 80 is provided on the first reinforcing member 70; wherein the length extension direction of the second reinforcing member 80 is parallel to the second direction y.

[0055] The second reinforcing member 80 is a limiting rib, which not only strengthens the structural strength of the first reinforcing member 70, but also makes the connection between the first cover plate 10 and the fixed housing 60 more secure, thereby further improving the assembly strength.

[0056] In some embodiments, a plurality of second reinforcing members 80 are provided on the first reinforcing member 70, and the plurality of second reinforcing members 80 are respectively located at both ends and the middle of the first reinforcing member 70 extending along the first direction x.

[0057] Understandably, by providing second reinforcing members 80 at both ends and the middle of the first reinforcing member 70, the first reinforcing member 70 can be uniformly reinforced.

[0058] In some embodiments, the first reinforcing member 70 includes a reinforcing member body 71, the two ends of which extend along the first direction x and are respectively connected to the sides of two adjacent connecting members 50 extending along the second direction y.

[0059] In some specific implementations, such as Figure 6 As shown, the first reinforcing member 70 has I-shaped connectors at both ends and the middle of its extension along the first direction x. The I-shaped connector includes a first plate body, a second plate body 72, and a first connecting portion 91 connecting the first plate body and the second plate body 72, all extending along the first direction x. The first plate body is the reinforcing member body 71, and the first connecting portion 91 is located in the middle of the second plate body 72 extending along the first direction x.

[0060] The outer edges of the two second plates 72 located at both ends of the first reinforcing member 70 are respectively connected to the sides of the two adjacent connecting members 50 extending along the second direction y. The outer edges of the two second plates 72 located at both ends of the first reinforcing member 70 are provided with second connecting portions 92, which are connected to the reinforcing member body 71.

[0061] Understandably, by forming I-shaped connectors at both ends and the middle of the first reinforcing member 70, a stable connection can be achieved through symmetrical support or interlocking structures on both sides. Furthermore, since the I-shaped connectors have the characteristics of high strength, torsion resistance, and easy assembly, the connection reliability and assembly convenience between the first cover plate 10 and the fixed housing 60 can be further improved.

[0062] In some embodiments, at least one second reinforcing member 80 is provided on each second plate 72, and at least one second reinforcing member 80 is provided on the reinforcing member body 71.

[0063] In some specific implementations, such as Figure 6 As shown, only one second reinforcing member 80 is provided on each of the two second plates 72 located at both ends of the first reinforcing member 70. Two second reinforcing members 80 are provided on the second plate 72 located in the middle of the first reinforcing member 70, and the two second reinforcing members 80 are distributed on both sides of the first connecting portion 91. One second reinforcing member 80 is provided at each end of the reinforcing member body 71, and they correspond to the second reinforcing members 80 provided on the second plates 72 located at the ends; two second reinforcing members 80 are provided in the middle of the reinforcing member body 71, and they correspond to the two second reinforcing members 80 provided on the second plates 72 located in the middle.

[0064] Understandably, by providing multiple second reinforcing members 80 on the first reinforcing member 70, the overall rigidity and structural strength of the first cover plate 10 can be further improved, as well as the stability of the connection between the first cover plate 10 and the fixed housing 60. At the same time, it can also effectively reduce the linear expansion or contraction of the first cover plate 10 at high or low temperatures, thereby further improving the deformation of the first cover plate 10.

[0065] Unlike related technologies, this application provides multiple connectors on both sides of the first cover plate extending in a first direction, and provides a first reinforcing member between two adjacent connectors. The two ends of the first reinforcing member extending in the first direction are respectively connected to the sides of the two adjacent connectors extending in a second direction. This allows multiple connectors to be connected into a whole through multiple first reinforcing members, thereby improving the overall rigidity and structural strength of the first cover plate, as well as the stability of the assembly between the first cover plate and the fixed housing. This effectively improves the deformation of the first cover plate, and makes the fit gap and fit discontinuity between the first cover plate and the top of the external device uniform, thereby improving the aesthetics of the vehicle screen and meeting the user's needs.

[0066] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
