[0030] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0031] Figure 1 is a three-dimensional view of a display screen assembly according to an embodiment of the utility model, Figure 2 yes Figure 1 The front view of the display assembly shown in Figure 3 is along Figure 2 The sectional view taken along the CC section shown in FIG. In the figure, the display screen assembly is generally indicated by reference numeral 1. Figure 1-3 It can be seen that the display screen assembly 1 includes a display screen 11, a first toothed component 13 and a second toothed component 14. The display screen assembly 1 is used to display information and / or receive input instructions. The first toothed component 13 is fixedly mounted on the first rotating shaft, one end of which is used to be rotatably connected to the fixed surface 12, and the other end is fixedly connected to the display screen 11. The second toothed component 14 is engaged with the first toothed component 13 over the rotation range of the display screen, and is fixedly mounted on the second rotating shaft, one end of which is used to be rotatably connected to the fixed surface 12. The second toothed component 14 is engaged with the first toothed component 13 over the rotation range of the display screen so that rotation can be transmitted to the rotating shaft, and at the same time, support of the display screen by the rotating shaft can be transmitted. In this embodiment, the second rotating shaft is a rotation damper, which is used to buffer the rotation speed of the display screen during the rotation of the display screen 11 to the horizontal or vertical display position.

[0032] It can be seen that the display screen assembly 1 according to this embodiment of the utility model can rotatably and stably hold the display screen 11 on the fixed surface 12 through two rotating shafts. It should be noted that only one end of the second rotating shaft is rotatably connected to the fixed surface 12, and the other end connected to the second toothed component 14 is suspended, so that sufficient degrees of freedom can be provided to enable the display screen 11 to achieve horizontal and vertical rotation, and at the same time, through the engagement of the first toothed component 13 fixed to the first rotating shaft and the second toothed component fixed to the second rotating shaft, reliable support is also provided for the display screen 11. Furthermore, by setting the second rotating shaft as a rotation damper, it can also play a buffering role on the rotation speed of the display screen rotating horizontally and vertically, avoiding damage to the display screen in the event of a collision due to rapid rotation.

[0033] The first toothed component 13 and the second toothed component 14 are preferably gears, and may also be a part of a gear, such as a sector gear, as long as the toothed parts thereof mesh over the rotation range of the display screen.

[0034] Figure 4 is along Figure 3 The sectional view taken at section AA shown in FIG. Figure 5 yes Figure 4 A magnified view of the circled portion U. Figure 4 and Figure 5 , the figure further shows the specific structure of the first rotating shaft and its connection method. Specifically, the first rotating shaft is indicated by the reference numeral 15. In this embodiment, the first rotating shaft 15 is a hollow wire sleeve, and the hollow part is used to facilitate the wires of the display screen to pass through it, so as to facilitate the connection and the wiring is neat. Preferably, a retaining spring 19 is also provided between the hollow wire sleeve and the edge of the hole on the fixed surface 12 to eliminate the installation gap caused by the error. One end of the first rotating shaft 15 is fixedly connected to the display screen 11, and the first toothed component 13 is fixedly connected to the first rotating shaft 15 near the display screen 11. The other end of the first rotating shaft 15 is rotatably connected to the fixed surface 12 through a bearing 17, and the bearing 17 is held in place by a sleeve 18, and the sleeve 18 is fixed to the fixed surface 12.

[0035] Figure 6 yes Figure 3 The enlarged view of the circled portion V is shown in FIG. Figure 3 and Figure 6 As can be seen, the figure shows the limit device according to this embodiment. Preferably, the limit device is set at the horizontal or vertical display position of the display screen. Although the display screen of this embodiment can also remain stationary in the horizontal or vertical display position without the limit device by adjusting the force balance, the solution of setting the limit device is the preferred solution, which is safer and more reliable. Figure 6As shown in the figure, the limiting device includes a cylinder 131 arranged on the surface of the first toothed component 13 facing the fixed surface 12, and a snap-fitting portion 181 arranged on the sleeve 18 of the fixed bearing and cooperating with the cylinder 131. The snap-fitting portion 181 is, for example, a step portion formed at the end of the sleeve of the fixed shaft bearing facing the first toothed component.

[0036] The limiting device of the present invention is not limited to the above structure, and any structure that can achieve limiting is within the scope of the present invention.

[0037] Figure 7 is along Figure 3 A cross-sectional view taken along section BB shown in FIG. Figure 8 yes Figure 7 The enlarged view of the circled portion W, combined with Figure 7 and Figure 8 , the figure further shows the specific structure of the second rotating shaft and its connection method. Specifically, the second rotating shaft 16 is a rotation damper, including two parts that can rotate relative to each other and provide buffered rotation, one of which is fixedly connected to the mounting surface 12, and the other is fixedly mounted to the second toothed component 14. The rotation damper can be, for example, a hydraulic damper or a friction damper.

[0038] Figures 1 to 8 It is a preferred embodiment of the utility model. The utility model is not limited to the specific details of the preferred embodiment, and it can be modified in many ways. For example, the first rotating shaft 15 can also be a solid shaft. In this case, the lead of the display screen can be routed to the other side of the fixed surface by opening another hole on the fixed surface. For another example, the first rotating shaft 15 can also be a rotary damper, that is, the first rotating shaft 15 and the second rotating shaft 16 can both be rotary dampers, and this solution can also achieve the technical effect of the above embodiment. Similarly, in this case, the lead of the display screen can be routed to the other side of the fixed surface by opening another hole on the fixed surface. For another example, the first rotating shaft 15 is a rotary damper, but the second rotating shaft 16 is a rotating shaft structure with one end suspended and a second gear installed, and the other end rotatably connected to the fixed surface through a bearing. In this case, the second rotating shaft can also be a solid or hollow wire sleeve. The various deformation forms are all within the protection scope of the utility model.

[0039] Fig. 9 1 is a three-dimensional view of a beverage preparation device according to an embodiment of the present invention. The beverage preparation device is generally indicated by reference numeral 100, and includes a display screen assembly 1 of the present invention that can rotate horizontally and vertically, wherein the fixed surface is a part of the surface of the case of the beverage preparation device 100. The beverage preparation device 100 is an automated beverage preparation device that can receive orders, display order information on the display screen assembly 1, and enable operators to input instructions to modify order information or beverage preparation information.

[0040] The display screen assembly 1 and beverage preparation device 100 of the utility model capable of being rotated horizontally and vertically can ensure that the display screen is safely and stably fixed, can be rotated horizontally and vertically frequently and arbitrarily, and will not be damaged in the event of a collision due to the rapid rotation of the display screen.
