[0002] With the development of information technology, automobiles are no longer limited to a means of transportation, but have become mobile terminals that integrate a variety of life and entertainment functions. The functions of in-vehicle systems are constantly being enriched, and in-vehicle projection screens have emerged as a result.

[0003] CN219872101U discloses a projection screen and a vehicle, where the projection screen can only be fully unfolded and fully retracted. However, in actual use, due to space constraints or usage requirements, people often need to display only a portion of the screen. Therefore, existing projection screens can no longer meet people's personalized needs. Utility Model Content

[0004] The purpose of this application is to provide a vehicle-mounted projection screen that can retract or extend a portion of the screen to present a stable image as needed.

[0005] The technical solution provided in this application is as follows:

[0006] A vehicle-mounted projection screen, comprising:

[0007] curtain;

[0008] Mounting brackets and curtain connectors are disposed opposite to each other at both ends of the curtain;

[0009] A curtain lifting assembly is disposed between the mounting base and the curtain connector. The curtain lifting assembly moves on its own to drive the curtain connector to rise and fall relative to the mounting base. The curtain lifting assembly includes a first limiting part, which is provided with a plurality of limiting points.

[0010] The first locking part and the first limiting part rotate, and the first locking part and the first limiting part cooperate to lock together, controlling the maximum distance of the curtain connector relative to the mounting base for lifting and lowering;

[0011] The first locking component connects the curtain lifting assembly and the curtain connector.

[0012] The second locking element connects the curtain lifting assembly and the mounting base.

[0013] In this application, the installation base, the screen connector, and the screen lifting assembly work together to achieve the unfolding and retraction of the screen. The screen lifting assembly, with its first limiting part having several limiting points, is locked in conjunction with the first locking part. This ensures stability when the screen is partially unfolded or retracted, allowing for the display of a quarter, one-third, or one-half of the vehicle projection screen, as well as the full screen, thus preventing vibrations during vehicle operation that could cause the vehicle projection screen to shake and affect the displayed image.

[0014] In one embodiment, the second locking member is hinged to the curtain lifting assembly to form a first hinge point, the second locking member is fixed on the mounting base, and the first limiting part rotates around the first hinge point.

[0015] In an embodiment of this application, the curtain lifting assembly is retracted and extended by hingedly connecting the second locking member to the curtain lifting assembly.

[0016] In one embodiment, the screen lifting assembly includes a first connecting arm, a connecting portion, and a second connecting arm, wherein the first connecting arm and the second connecting arm are respectively hinged to the connecting portion; when the vehicle projection screen is unfolded, the first connecting arm and the second connecting arm form a "V" shape; when the vehicle projection screen is retracted, the first connecting arm and the second connecting arm are retracted and placed at the mounting base.

[0017] In an embodiment of this application, the screen lifting assembly includes a first connecting arm, a connecting portion, and a second connecting arm. The first connecting arm is hinged to the connecting portion, and the second connecting arm is hinged to the connecting portion. With this configuration, the connecting portion serves as the connection point between the first and second connecting arms, allowing both the first and second connecting arms to rotate around the connecting portion. This enables the following: when the vehicle-mounted projection screen needs to be unfolded, the first and second connecting arms form a "V" shape with the connection point as the center; when not needed, the first and second connecting arms retract, thereby retracting the vehicle-mounted projection screen.

[0018] In one embodiment, the connecting portion, the first connecting arm, and the second connecting arm are connected through a locking portion.

[0019] In the embodiments of this application, the locking part passes through the connecting part, the first connecting arm and the second connecting arm to prevent any part at the connection from falling off, thereby enhancing the stability of the screen lifting assembly and thus enhancing the stability of the vehicle projection screen.

[0020] In one embodiment, a shielding cover is provided on the surface of the connection portion away from the direction of the curtain.

[0021] In the embodiments of this application, a cover is provided on the surface of the connecting portion to prevent the locking portion from being exposed to the outside for a long time and oxidizing, thereby extending the service life of the locking portion. Furthermore, since the locking portion is exposed and somewhat abrupt, covering it ensures aesthetics.

[0022] In one embodiment, the first connecting arm includes a first connecting member, a first arm body, and a second connecting member connected in sequence. The first connecting member is hinged to the second locking member, and the second connecting member is hinged to the connecting portion.

[0023] In the embodiments of this application, the partitioned design of the first connecting arm ensures the functional stability of each component and enhances the reliability of the first connecting arm.

[0025] In the embodiments of this application, the partitioned design of the second connecting arm ensures the functional stability of each component and enhances the reliability of the second connecting arm.

[0026] In one embodiment, the first arm is a tubular structure that is plugged into the first connector and the second connector.

[0027] In the embodiments of this application, the first arm body is configured as a tubular structure to facilitate its insertion and connection with the first connector and the second connector.

[0028] In one embodiment, the second arm is a tubular structure that is inserted into the third connector and the fourth connector.

[0029] In the embodiments of this application, the second arm is configured as a tubular structure to facilitate its insertion and connection with the third connector and the fourth connector.

[0030] In one embodiment, the vehicle-mounted projection screen is mounted on the top of the vehicle body.

[0031] In this embodiment, the vehicle-mounted projection screen is installed on the top of the vehicle body. This allows it to be lowered from the top of the vehicle body for viewing when needed, and retracted when not in use. Attached Figure Description

Detailed Implementation

[0039] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0040] Figure 1 A schematic diagram of the rear of the fully extended in-vehicle projection screen; Figure 2 for Figure 1 A magnified view of part A in the image; Figure 3 A schematic diagram of the rear of the in-vehicle projection screen when it is fully extended; Figure 4 for Figure 3 A magnified view of part B in the image.

[0041] like Figures 1 to 4 As shown, a vehicle-mounted projection screen 100 includes a screen 140; a mounting base 110 and a screen connector 150, which are disposed opposite each other at both ends of the screen 140; and a screen lifting assembly (not shown) disposed between the mounting base 110 and the screen connector 150. One end of the screen lifting assembly is connected to the screen connector 150 via a first locking member 160, and the other end is connected to the mounting base 110 via a second locking member 170. The mounting base 110, the screen connector 150, and the screen lifting assembly work together to achieve the unfolding and retraction of the screen 140.

[0042] The screen lifting assembly moves by itself, causing the screen connector 150 to rise and fall relative to the mounting base 110, thereby partially unfolding the screen 140 and enabling the display of one-quarter, one-third, one-half, or other parts or the full screen of the vehicle projection screen 100.

[0043] The screen lifting assembly includes a first limiting part 1314, which has several limiting points. The vehicle-mounted projection screen 100 has a first locking part 180 that matches the first limiting part 1314. The first limiting part 1314 and the first locking part 180 work together to control the maximum lifting distance of the screen connector 150 relative to the mounting base 110, thereby controlling the size of the imaging display area of ​​the vehicle-mounted projection screen 100. The multiple limiting points of the first limiting part 1314, linked and locked with the first locking part 180, ensure stability when displaying a quarter, one-third, one-half, or other portions of the vehicle-mounted projection screen 100, as well as the entire screen, preventing vibrations during vehicle movement that could cause the projection screen to shake up and down, thus affecting the displayed image.

[0044] When there are multiple imaging display sizes required for the vehicle-mounted projection screen 100, the first limiting part 1314 is equipped with a corresponding number of limiting points. By locking the limiting points, the screen lifting assembly is locked to prevent the screen connector 150 from sliding relative to the mounting base 110, thus preventing shaking during vehicle operation and causing the vehicle-mounted projection screen to sway up and down, thereby enhancing the stability of the displayed image. For example, if the vehicle-mounted projection screen 100 is required to achieve half-screen display, at least two limiting points are set: one limiting point is used to control full-screen display; and the other limiting point is used to control the locking of the first limiting part 1314 and the first locking part 180 when displaying half-screen. For example, if the vehicle-mounted projection screen is required to display both half-screen and one-third-screen, then at least three limiting points are set: one limiting point for controlling full-screen display; one limiting point for locking the first limiting part 1314 and the first locking part 180 when displaying half-screen; and one limiting point for locking the first limiting part 1314 and the first locking part 180 when displaying one-third-screen. If N display scenarios are required, then at least N+1 limiting points are set.

[0045] When different screen display requirements need to be met, the first limiting part 1314 rotates to the corresponding limiting point and locks in place in conjunction with the first locking part 180.

[0046] In the embodiments of this application, the second locking member 170 is fixed on the mounting base 110, and the second locking member 170 is hinged to the screen lifting assembly to form a first hinge point (not shown in the figure). In this way, the first limiting part 1314 of the screen lifting assembly can rotate around the first hinge point. By rotating the first limiting part 1314 relative to the first hinge point, the screen lifting assembly is controlled, thereby controlling the opening and closing of the screen lifting assembly, controlling the distance of the screen connector 150 relative to the mounting base 110, and controlling the size area of ​​the screen 140 imaging display area.

[0047] In the embodiments of this application, the first locking member 160 is fixedly installed on the curtain connector 150, and the first locking member 160 can be hinged to the curtain lifting assembly. This arrangement reduces the resistance between the first locking member 160, the curtain connector 150, and the curtain lifting assembly when the curtain lifting assembly is retracted or extended, allowing the curtain connector 150 and the curtain lifting assembly to cooperate better.

[0048] In an embodiment of this application, the screen lifting assembly includes a first connecting arm 131, a connecting portion 133, and a second connecting arm 132. The first connecting arm 131 is hinged to the connecting portion 133, and the second connecting arm 132 is hinged to the connecting portion 133. With this configuration, the connecting portion 133 serves as the connection point between the first connecting arm 131 and the second connecting arm 132, allowing both the first and second connecting arms 131 and 132 to rotate around the connecting portion. Thus, when the vehicle-mounted projection screen 100 needs to be unfolded, the first connecting arm 131 and the second connecting arm 132 form a "V" shape with the connection point as the center; when not needed, the first connecting arm 131 and the second connecting arm 132 retract, thereby retracting the vehicle-mounted projection screen 100.

[0049] In the embodiments of this application, when the vehicle-mounted projection screen 100 is retracted, the first connecting arm 131 and the second connecting arm 132 are retracted and placed at the mounting base 110, where they can be directly embedded. In this way, the screen lifting assembly, the screen 140, etc., are retracted and form a whole with the mounting base 110, ensuring the aesthetics of the vehicle-mounted projection screen 100.

[0050] In the embodiments of this application, the connecting part 133, the first connecting arm 131, and the second connecting arm 132 are connected through the locking part 134. In this way, the connecting part 133, the first connecting arm 131, and the second connecting arm 132 are directly connected in series, which prevents any part of the connecting part 133, the first connecting arm 131, and the second connecting arm 132 from falling off, thereby enhancing the stability of the screen lifting assembly and thus enhancing the stability of the vehicle projection screen 100.

[0051] In the embodiments of this application, holes can be reserved in the first connecting arm 131, the second connecting arm 132 and the connecting part 133 respectively, so that bolts, screws, rivets and the like can be used as locking parts 134 for locking and fixing.

[0052] In the embodiments of this application, a cover can be provided on the surface of the connecting portion 133 in a direction away from the screen 140 to cover the surface of the locking portion 134. This prevents dust from entering and avoids long-term oxidation of the locking portion 134, thus extending its service life. In addition, the exposed locking portion 134 can appear somewhat abrupt in some areas; covering it ensures the aesthetics of the area.

[0053] In the embodiments of this application, the first connecting arm 131 includes a first connecting member 1311, a first arm body 1312, and a second connecting member 1313 connected in sequence. The first connecting member and the second locking member 170 are hinged together, and the second connecting member 1313 and the connecting portion 133 are hinged together. In this way, the partitioned design of the first connecting arm 131 ensures the functional stability of each component, thereby enhancing the reliability and stability of the first connecting arm 131.

[0054] In the embodiments of this application, the first arm 1312 can be a tubular structure, thereby reducing the weight of the screen lifting assembly and thus reducing the weight of the vehicle-mounted projection screen 100. In addition, the first arm 1312 can be directly plugged into the first connector 1311 and the second connector 1313, making installation simple and easy to operate.

[0055] In the embodiments of this application, holes can be pre-drilled in the connection areas of the first arm 1312 and the first connector 1311, so that bolts, screws, or rivets can be used for further tightening and fixing, thereby enhancing the stability of the first connecting arm 131. Similarly, holes can also be pre-drilled in the connection areas of the first arm 1312 and the second connector 1313, so that bolts, screws, or rivets can be used for further tightening and fixing, thereby enhancing the stability of the first connecting arm 131.

[0056] In the embodiments of this application, the second connecting arm 132 includes a third connecting member 1321, a second arm body 1322, and a fourth connecting member 1323 connected in sequence. The third connecting member 1321 is hinged to the first locking member 160, and the fourth connecting member 1323 is hinged to the connecting portion 133. This partitioned design of the second connecting arm 132 ensures the functional stability of each component, thereby enhancing the reliability and stability of the second connecting arm 132.

[0057] In the embodiments of this application, the second arm 1322 can be a tubular structure, thereby reducing the weight of the screen lifting assembly and thus the weight of the vehicle-mounted projection screen 100. Furthermore, the second arm 1322 can be directly plugged into the third connector 1321 and the fourth connector 1323, making installation simple and easy to operate.

[0058] In the embodiments of this application, holes can be pre-drilled in the connection areas of the second arm 1322 and the third connector 1321, so that bolts, screws, or rivets can be used for further locking and fixing, thereby enhancing the stability of the second connecting arm 132. Similarly, holes can be pre-drilled in the connection areas of the second arm 1322 and the fourth connector 1323, so that bolts, screws, or rivets can be used for further locking and fixing, thereby enhancing the stability of the second connecting arm 132.

[0059] In an embodiment of this application, the vehicle-mounted projection screen 100 further includes a telescopic driver 190, and the first locking part 180 is telescopically extended and retracted by the telescopic driver 190. When the screen 140 begins to unfold, the telescopic driver 190 controls the first locking part 180 to retract, releasing the restriction on the first limiting part 1314 of the screen lifting assembly, facilitating the unfolding of the screen 140; when the screen 140 is unfolded to the required extent, the telescopic driver 190 controls the first locking part 180 to extend, cooperating with the first limiting part 1314 of the screen lifting assembly to lock it. The telescopic controller 190 may consist of two parts: a telescopic rod 191 and a housing 192.

[0060] In the embodiments of this application, the mounting base 110 includes a base, a screen retractor, and a receiving cavity. Thus, the base can be used to mount other structural components, and the screen retractor is rotatably mounted on the base, retracting or unretracting the screen 140. When the screen 140 is retracted by the screen retractor, it is placed within the receiving cavity of the mounting base 110, which improves the aesthetics of the vehicle-mounted projection screen 100.

[0061] Figure 5 This is a schematic diagram of the vehicle structure according to an embodiment of this application. Figure 5 As shown, this application allows the vehicle-mounted projection screen 100 to be installed on the top of the vehicle body 300, thus forming a vehicle 10 with projection display function. With this configuration, the mounting base 11 can be directly embedded into the top of the vehicle body 300, and the vehicle-mounted projection screen 100 can be completely retracted into the vehicle body 300. Thus, when needed, it can be lowered from the top of the vehicle body 300 for viewing; when not needed, it can be retracted into the top of the vehicle body 300. This ensures both the neatness and aesthetics of the vehicle interior and the ability of the vehicle-mounted projection screen 100 to display as needed.
