[0033] The limiting portion 13 is toggled in the limiting groove 121 to disengage the limiting portion 13 from the clamping groove 111, the angle of the movable seat 11 relative to the fixed seat 12 is adjusted to a preset angle, and then the limiting portion 13 is snapped into the clamping groove 111 to lock the preset angle. That is, the limiting portion 13 moves back and forth in the long-strip-shaped limiting groove 121. When the limiting portion 13 is snapped into the clamping groove 111, the preset angle is locked; when the limiting portion 13 is disengaged from the clamping groove 111, the movable seat 11 can move relative to the fixed seat 12, so as to adjust the angle between the two.

[0034] As Figure 1 shown, in some embodiments of the present utility model, the limiting portion 13 includes a limiting shaft 131 and an elastic element 132 fixedly connected. The limiting shaft 131 is located in the limiting groove 121. The limiting shaft 131 is toggled in the limiting groove 121, and the elastic element 132 is compressed. After the angle of the movable seat 11 relative to the fixed seat 12 is adjusted to a preset angle, the limiting shaft 131 is released, and the elastic element 132 resets, driving the limiting shaft 131 to be snapped into the clamping groove 111 to lock the preset angle. That is, through the design of the elastic element 132, the limiting shaft 131 is reset to be snapped into the clamping groove 111, thereby locking the preset angle.

[0035] As Figure 1 shown, in some embodiments of the present utility model, the fixed seat 12 includes a bottom plate 122, a first fixing plate 123, and a second fixing plate 124. The first fixing plate 123 and the second fixing plate 124 are respectively arranged on opposite sides of the bottom plate 122.

The limiting groove 121 includes a first limiting groove and a second limiting groove, that is, the first limiting groove and the second limiting groove are respectively arranged on the first fixing plate 123 and the second fixing plate 124. The limiting shaft 131 passes through the first limiting groove and the second limiting groove respectively, that is, the limiting shaft 131 moves in the first limiting groove and the second limiting groove, so as to disengage from or be snapped into the clamping groove 111. One side of the elastic element 132 is fixedly connected to the limiting shaft 131, and the other side is arranged on the bottom plate 122 to achieve the reset function.

[0036] As Figure 1As shown, in some embodiments of the present utility model, the fixed seat 12 is further provided with a through hole. The movable seat 11 and the fixed seat 12 are connected by a connecting shaft 14 passing through the through hole. For example, the first fixing plate 123 and the second fixing plate 124 are respectively provided with opposite through holes.

[0037] As Figure 1 shown, in some embodiments of the present utility model, a ratchet wheel is provided at one end of the movable seat 11 connected to the fixed seat 12, and the ratchet groove on the ratchet wheel is the clamping groove 111. Of course, the structure of the clamping groove 111 is not specifically limited, and any structure that can achieve the function of the clamping groove 111 can be used. The two ratchet wheels are respectively connected to the first fixing plate 123 and the second fixing plate 124 by a connecting shaft 14 passing through the two through holes. The number of the clamping grooves 111 needs to be set to multiple to adapt to that there is still a corresponding clamping groove 111 to clamp the limiting shaft 131 after the movable seat 11 adjusts the angle relative to the fixed seat 12. The specific number of the clamping grooves 111 is set according to specific requirements.

[0038] As Figure 1 shown, in some embodiments of the present utility model, the elastic element 132 is a spring. Selecting a spring has a simple structure and saves costs.

[0039] As Figures 2 - 5 shown, an embodiment of the present utility model further provides an adjustable-angle display screen, including: a mounting mechanism 2, an angle adjustment mechanism 1, a display screen 3, and a support mechanism 4. One side of the mounting mechanism 2, such as the front, mounts the display screen 3, and the other side of the mounting mechanism 2, such as the back, mounts the angle adjustment mechanism 1 and the support mechanism 4. After the preset angle adjustment is performed through the angle adjustment mechanism 1, the support mechanism 4 is used to support the display screen 3 with the adjusted angle.

[0040] The adjustable-angle display screen of the present utility model adjusts the tilt angles of different display screens 3 through the angle adjustment mechanism 1. Specifically, the angle between adjacent display screens 3 is adjusted by adjusting the included angle between the movable seat 11 and the fixed seat 12, so as to display various traffic information to drivers in different positions through the display screens 3 at different angles, effectively improving the highway management ability and traffic efficiency. The tilt angle of the display screen 3 can be adjusted according to the actual use situation and road conditions, and it can be widely applied to various multi-angle display scenarios. The angle adjustment structure of the present utility model is simple and easy to operate.

[0041] It should be noted that the angle adjustment mechanism 1 and the support mechanism 4 can be installed between adjacent display screens 3 that need to adjust the angle, so as to realize the multi-angle adjustment of multiple display screens 3. At least two display screens 3 are provided. In the embodiments herein, two display screens 3 are used as examples, namely the first display screen 31 and the second display screen 32.

[0042] As Figure 1 andFigure 2 As shown in Figure 2 , in some embodiments of the present utility model, the installation mechanism 2 includes a first mounting bracket 21 and a second mounting bracket 22. The movable seat 11 is mounted on the first mounting bracket 21, and the fixed seat 12 is mounted on the second mounting bracket 22. That is, the first mounting bracket 21 and the second mounting bracket 22 are movably connected together through the connection between the movable seat 11 and the fixed seat 12. The angle adjustment between the movable seat 11 and the fixed seat 12 is the angle adjustment between the first mounting bracket 21 and the second mounting bracket 22.

[0043] As Figure 2 shown in Figure 2 , in some embodiments of the present utility model, the angle-adjustable display screen further includes a support mechanism 4. The support mechanism 4 includes a sleeve rod 41 and a telescopic rod 42. One end of the telescopic rod 42 is mounted on the second mounting bracket 22, and the other end of the telescopic rod 42 is sleeved on one end of the sleeve rod 41, and the other end of the sleeve rod 41 is mounted on the first mounting bracket 21. By designing the sleeve rod 41 and the telescopic rod 42, and the rod diameter of the sleeve rod 41 is greater than the rod diameter of the telescopic rod 42, the telescopic rod 42 can perform telescopic activities in the sleeve rod 41, so as to adaptively adjust the position of the telescopic rod 42 in the sleeve rod 41 according to, for example, the angle between the first display screen 31 and the second display screen 32. After adjustment, the telescopic rod 42 and the sleeve rod 41 are locked and fixed. The sleeve rod 41 and the telescopic rod 42 provide an oblique support force to obliquely pull and stabilize the positions of the first display screen 31 and the second display screen 32.

[0044] As Figure 2 shown in Figure 2 , in some embodiments of the present utility model, the installation mechanism 2 further includes a suspension rod 23. The suspension rod 23 is connected to the first mounting bracket 21, that is, the suspension rod 23 is mounted on the first mounting bracket 21. For example, the suspension rod 23 and the first mounting bracket 21 are connected by bolts. By designing the suspension rod 23, the angle-adjustable display screen of the present utility model is suspended and installed.

[0045] As Figure 3 , Figure 4 and Figure 5 shown in Figure 3 , Figure 4 and Figure 5 , in some embodiments of the present utility model, the angle-adjustable display screen further includes a plurality of display screens 3. Each display screen 3 is formed by splicing a plurality of display units. And each display screen 3 can display different contents to meet different requirements. Exemplarily, the display screen 3 is an LED display screen.

[0046] The adjacent display screens 3 are respectively mounted on the first mounting bracket 21 and the second mounting bracket 22. Specifically, the first display screen 31 is mounted on the first mounting bracket 21, and the second display screen 31 is mounted on the second mounting bracket 22. By adjusting the angle between the movable seat 11 and the fixed seat 12, the angle between the first mounting bracket 21 and the second mounting bracket 22 is changed, and thus the angle between the first display screen 31 and the second display screen 32 is adjusted. That is, the angle between the first display screen 31 and the second display screen 32 is adjusted by adjusting the angle between the movable seat 11 and the fixed seat 12, with a simple structure and convenient operation.

[0047] For example, the first display screen 31 is perpendicular to the ground, and there is a certain angle between the second display screen 32 and the first display screen 31. That is, the first display screen 31 is vertically mounted, and the second display screen 32 is mounted after being adjusted to a certain inclination angle by the angle adjusting mechanism 1 and is obliquely supported by the support mechanism 4. The adjustable-angle display screen of the present invention is generally hoisted above the ETC dedicated lane. The first display screen 31 can be used to display basic passing information such as fees or license plates, and the second display screen 32 transmits passing information to the drivers passing through the ETC lane to determine that the vehicle has successfully paid the fee and can pass, or releases the latest traffic operation conditions to the drivers, such as congestion, accidents or construction information, and provides route selection suggestions to help the driver select the optimal route to relieve traffic congestion. Of course, the content to be presented on the display screen 3 should be specifically designed according to the specific usage situation.

[0048] Such as Figure 5 As shown, in some embodiments of the present invention, the angle of the movable seat 11 relative to the fixed seat 12 is 20 degrees to 180 degrees. That is, the angle adjustment range between adjacent display screens is 20 degrees to 180 degrees. Specifically: the angle between the first mounting bracket 21 and the second mounting bracket 22 is 20 degrees to 180 degrees, that is, the angle between the first display screen 31 and the second display screen 32 is 20 degrees to 180 degrees. In the actual usage scenario, the angle between the first display screen 31 and the second display screen 32 is adjusted to 30° to 45°. Specifically, it can be specifically limited according to the lane distance and the upward viewing angle.

[0049] It should be noted that the specific number of the display screens 3 should be specifically designed according to the actual situation. Each pair of adjacent display screens 3 can be specifically adjusted in angle by the angle adjusting mechanism 1 of the present invention, and the specific number of the angle adjusting mechanism 1, the support mechanism 4, the first mounting bracket 21, and the second mounting bracket 22 is specifically designed according to the size of the required display screen 3. For example, the angle between the first display screen 31 and the second display screen 32 is adjusted by two angle adjusting mechanisms 1, and two corresponding first mounting brackets 21 and second mounting brackets 22 are respectively equipped to mount two corresponding movable seats 11 and fixed seats 12, and two support mechanisms 4 are simultaneously equipped for support.

[0050] In some embodiments of the present utility model, the angle-adjustable display screen is further provided with a brightness, temperature and humidity sensor, so as to realize temperature and humidity acquisition and automatic brightness adjustment to meet the actual functional use.

[0051] In some embodiments of the present utility model, a waterproof power supply box and a waterproof connector are installed on one side of each display unit for installing power supplies and the like.

[0052] In summary, the present utility model designs the movable seat, fixed seat and limiting part of the angle adjustment mechanism. The movable seat is provided with a plurality of clamping grooves corresponding to the preset angles. The fixed seat is provided with a limiting groove. When the limiting shaft of the limiting part is toggled in the limiting groove, that is, the limiting shaft is moved to another position of the limiting groove to disengage it from the clamping groove. At the same time, the limiting shaft also compresses the elastic element. At this time, the angle between the movable seat and the fixed seat is adjusted. After adjusting to the preset angle, the limiting shaft is released. Through the reset of the elastic element, the limiting shaft is driven to slide back to the clamping groove in the limiting groove to lock the preset angle between the movable seat and the fixed seat. At the same time, a display screen is installed on one side of the first mounting frame and the second mounting frame respectively, and a movable seat and a fixed seat are installed on the other side of the first mounting frame and the second mounting frame respectively. That is, the preset angle between the movable seat and the fixed seat is the preset angle between the first mounting frame and the second mounting frame, that is, the preset angle between adjacent display screens. That is to say, the adjustment of the preset angle between adjacent display screens is realized by adjusting the angle between the movable seat and the fixed seat. The angle-adjustable display screen of the present utility model can display different traffic road information to drivers in different positions through display screens at different angles, reduce the visual blind area of drivers, clearly see the road information displayed on the display screen, and contribute to road traffic safety and smoothness.

[0053] The above embodiments only illustratively explain the principles and effects of the present utility model, rather than limiting the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
