[0032] A display screen is a device used to display various information such as text, images, videos and recordings. When showing it to customers, existing display screens can only be placed upright or flat on the ground to play videos or pictures, which does not provide a good viewing experience and is not conducive to display.

[0033] The main purpose of the utility model is to provide a display device, aiming to at least solve the technical problem in the related art that the display device for display can only be erected or laid flat on the ground to play videos or display pictures, which results in a poor viewing experience and is not conducive to display.

[0034] See also Figure 1 and Figure 2 In one embodiment of the utility model, the display device 100 includes a base 1, a display screen 2 and a driving member 2. The display screen 2 can be movably arranged in the up and down directions relative to the base 1, and can be rotatably arranged along a horizontally extending axis relative to the base 1. The driving member 2 includes a first driving part 21 and a second driving part 22 which are drivingly connected to the display screen 2. The first driving part 21 is used to drive the display screen 2 to move in the up and down directions, and the second driving part 22 is used to drive the display screen 2 to rotate.

[0035] In the technical solution of the present utility model, the display screen 2 is arranged on the base 1, can be movably arranged in the up and down directions relative to the base 1, and can be rotatably arranged along the horizontally extending axis relative to the base 1, and also includes a first driving part 21 and a second driving part 22 driven and connected to the display screen 2, the first driving part 21 is used to drive the display screen 2 to move in the up and down directions, and the second driving part 22 is used to drive the display screen 2 to rotate; with such an arrangement, when displaying to the user, the display screen 2 can be driven to move in the up and down directions by the first driving part 21, and can also be driven to rotate by the second driving part 22, so that the height and angle of the display screen 2 can be changed and adjusted to a suitable position, giving the user a better experience.

[0036] In order to prevent the height adjustment and angle adjustment of the display screen 2 from interfering with each other, in some embodiments, the second driving unit 22 can be arranged to move in the up-down direction relative to the base 1; the first driving unit 21 is connected to the second driving unit 22 to drive the second driving unit 22 to move in the up-down direction, so as to drive the display screen 2 to move in the up-down direction. In this way, the second driving unit 22 can directly drive the display screen 2 to rotate, that is, change the angle of the display screen 2, and the first driving unit 21 drives the second driving unit 22 to move, so that the second driving unit 22 can move upward or downward, thereby driving the display screen 2 to move upward or downward, thereby changing the height of the display screen 2, and achieving the height and angle adjustment without interfering with each other.

[0037] The method of adjusting the height and angle without interfering with each other is not limited to this. In some embodiments, the first driving part 21 can rotate along the horizontally extending axis relative to the base 1, and the second driving part 22 is connected to the first driving part 21 to drive the first driving part 21 to rotate, so as to drive the display screen 2 to rotate. In this way, the activation of the second driving part 22 will drive the first driving part 21 and the display screen 2 to change their angles, and then the first driving part 21 will drive the change of the height of the display screen 2. In contrast, this method will cause the first driving part 21 to not only change the height of the display screen 2, but also drive the display screen 2 to move forward or backward when changing the height of the display screen 2.

[0038] Of course, the first driving part 21 and the second driving part 22 can work together to change the height and angle of the display screen 2. For example, when the first driving part 21 and the second driving part 22 are both configured as cylinders that are rotatably connected to the base 1 and the display screen 2 at both ends, when one of the cylinders is started, the angle of the display screen 2 can be changed. When the two cylinders are started at the same time, the height of the display screen 2 can be changed.

[0039] It is understandable that if the first driving unit 21 and the second driving unit 22 are directly connected, the number of the first driving unit 21 and the second driving unit 22 needs to be consistent, but this will bring certain limitations and inconvenience to the installation during actual installation. Therefore, in some embodiments, please refer to Figure 1 and Figure 2 The display device 100 further includes a support plate 3, which can be movably arranged in the up-down direction relative to the base 1; one end of the display screen 2 is rotatably arranged with the support plate 3 along a horizontally extending axis, and the second driving unit 22 is arranged on the support plate 3; the first driving unit 21 is drivingly connected with the support plate 3 to drive the support plate 3 to move in the up-down direction, so as to drive the second driving unit 22 to move in the up-down direction. With such arrangement, when it is necessary to adjust the height of the display screen 2, the first driving unit 21 is controlled to work, driving the support plate 3 to move up-down, and then the second driving unit 22 and the display screen 2 to move up-down through the support plate 3. The arrangement of the support plate 3 makes it unnecessary for the number of the first driving unit 21 and the second driving unit 22 to completely correspond, which is more convenient for actual production.

[0040] The first driving part 21 has various forms, and can drive the support plate 3 to move up and down through a threaded structure. In the embodiment of the present application, the first driving part 21 includes a first telescopic member, one end of which is fixedly connected to the support plate 3, and the other end is fixedly connected to the base 1. In this way, the support plate 3 is driven to move up and down through the telescopic form, thereby changing the height of the display screen 2. In comparison, the height adjustment of the threaded structure often requires the threaded rod to be longer than the movable stroke of the display screen 2. Even when the display screen 2 is at the lowest point, the threaded rod remains stationary, resulting in a relatively large overall structure. For the display device 100 that needs to be displayed to customers, it is not convenient to carry and not beautiful enough.

[0041] The first telescopic member may be in various specific forms, for example, it may be a pneumatic cylinder, an oil cylinder or an electric push rod.

[0042] Since the display device 100 proposed in the present application is used for display, it needs to be carried and transported, and bumps are inevitable during the carrying and transportation process, which may cause damage to the display screen 2. Therefore, in some embodiments, please refer to Figure 2 and Figure 3A buffer member 4 is further provided between the base 1 and the support plate 3. Thus, the buffer member 4 is provided to reduce the impact force of the base 1 on the support plate 3, thereby reducing the impact force on the display screen 2, and having a certain protective effect on the display screen 2.

[0043] The buffer 4 has various forms. In some embodiments, the buffer 4 includes a spring 41 extending in the longitudinal direction, one end of the spring 41 is fixedly connected to the base 1, and the other end is connected to the support plate 3; in this way, the impact force of the base 1 on the display screen 2 can be weakened by the elastic deformation of the spring 41, so as to protect the display screen 2; the other end of the spring 41 can be fixed to the support plate 3, or it can just be against the bottom of the support plate 3. Of course, if it is just against, it is necessary to make the spring 41 in a compressed state to avoid the spring 41 being separated from the support plate 3 during transportation and carrying and not playing a good buffering role. The present design is not limited to this. The buffer 4 can also be a flexible object such as a rubber pad and a sponge pad. Of course, when the buffer 4 is a rubber pad and a sponge pad, it cannot be fixed to the support plate 3 to avoid damage to the rubber pad and the sponge pad during the upward movement of the support plate 3.

[0044] In order to ensure that the existence of the first driving part 21 does not affect the function of the buffer 4, in an embodiment of the present application, the first driving part 21 includes an oil cylinder, and the two ends of the oil cylinder are fixedly connected to the support plate 3 and the base 1 respectively; it should be noted that when the oil cylinder is not started, it can also perform a small extension and contraction by itself to avoid fixing the base 1 and the support plate 3, thereby making the buffer 4 unable to play a buffering role; with such an arrangement, when the display screen 2 is shaken during transportation and carrying, the buffer 4 reduces the impact force on the display screen 2, and the oil cylinder will also extend and contract at the same time, which can convert kinetic energy into heat energy and also play the role of a damping rod to reduce the possibility of repeated vibration of the support plate 3 and the display screen 2.

[0045] The second driving part 22 has various forms. In some embodiments, the height of the other end of the display screen 2 can be changed by a threaded structure, thereby driving the display screen 2 to rotate and adjust the angle. In the embodiments of the present application, please refer to Figure 1 and Figure 2The second driving part 22 includes a second telescopic member, one end of which is rotatably connected to the display screen 2, and the other end is rotatably connected to the support plate 3; with such a configuration, the angle of the display screen 2 can be quickly adjusted by the extension and retraction of the second telescopic member, and when fully retracted, the distance between the support plate 3 and the display screen 2 will not be very large, which is more convenient to carry; in contrast, the method of adjusting the angle of the support plate 3 by a threaded structure, the structure of the support plate 3 itself will occupy a larger space, affecting the size of the overall structure. Secondly, the adjustment of the threaded structure also needs to consider the problem of motion interference during the adjustment of the display screen 2, and the overall structure is more complicated.

[0046] In order to better protect the overall structure during carrying and transportation, in an embodiment of the present application, the base 1 includes a box body 11, and an opening 111 connected to its inner cavity is arranged on the top of the box body 11, and the opening 111 is used to avoid the movement of the display screen 2; in this way, the base 1 is arranged in the form of the box body 11, and the box body 11 is provided with the opening 111. When not in use, the first driving part 21 and the second driving part 22 can drive the display screen 2 to move through the opening 111 into the box body 11, and the display screen 2 is protected by the box body 11, and the power supply, controller, wires, etc. related to the first driving part 21 and the second driving part can also be hidden in the box body 11, which will not appear messy and affect the display effect to the user.

[0047] In order to make it more convenient to carry, a handle or the like may be provided on the box body 11 , and rollers may also be provided under the box body 11 .

[0048] Of course, the box body 11 is provided with a cover and a cover plate of the opening 111, and the cover plate is detachably connected to the box body 11; when not in use, the display screen 2 is retracted into the box body 11, and the cover plate can be covered to prevent foreign matter from entering the box body 11 through the opening 111, and the cover plate can be removed when in use.

[0049] There are many ways to control the first driving unit 21 and the second driving unit 22, for example, they can be controlled by a switch, or by a remote control or wireless control of a mobile device; in the embodiment of the present application, please refer to Figure 4 At least two control switches 5 are provided on the base 1 , and the two control switches 5 are electrically connected to the first driving part 21 and the second driving part 22 respectively, which is simple and quick.

[0050] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
