Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a display screen pushing mechanism and a wave display screen. Background Art

[0002] Traditional display screens (such as advertising screens or exhibition hall screens) are generally a whole flat structure. In order to achieve better visual effects, a wave display screen has emerged. The wave display screen is composed of several pushing mechanisms and display screen units. A display screen unit is set on each pushing mechanism. When in use, by controlling each pushing mechanism to expand and contract in a preset manner, each display screen unit can be made to rise and fall in a preset manner. Combined with the display images on each display screen, the effect of the upper image moving can be achieved, which can produce a better visual effect.

[0003] At present, the ejection mechanism is usually driven by a motor, but the motor will generate a lot of heat when working.

The poor heat dissipation effect makes the temperature of the ejection mechanism in the middle higher, causing the electronic components to fail to work normally, thus affecting the service life of the electronic components.

[0035] The utility model provides a display screen pushing mechanism.

[0036] In the embodiment of the present utility model, Figures 1 to 6As shown, the display screen ejection mechanism includes: an installation box 10, a fixing structure 20, a movable component 30, a driving mechanism 40 and a heat dissipation fan 50.

[0037] Specifically, the installation box 10 has a front plate 11 and a rear plate 12 that are relatively arranged, the front plate 11 is provided with a first opening 111, and the rear plate 12 is provided with a second opening 121, and an air duct 13 is formed between the first opening 111 and the second opening 121; the fixed structure 20 is installed on the rear plate 12 and is located in the air duct 13; the movable component 30 includes a movable cylinder 31 and a mounting plate 32, the movable cylinder 31 is slidably installed on the fixed structure 20, and the end of the movable cylinder 31 away from the fixed seat 21 extends out from the first opening 111 and is connected to the mounting plate 32, and the mounting plate 32 is used to install the display screen; the driving mechanism 40 includes a motor 41 and a transmission structure 42, the motor 41 is installed on the fixed component, and the motor 41 is connected to the movable cylinder 31 through the transmission structure 42, so as to drive the movable cylinder 31 to slide relative to the fixed structure 20; the heat dissipation fan 50 is arranged in the installation box 10, so as to drive the airflow to enter the air duct 13 from the first opening 111 and then be discharged from the second opening 121.

[0038] It can be understood that when the airflow flows through the motor 41, it can exchange heat with the motor 41 to take away the heat of the motor 41, thereby achieving heat dissipation and cooling of the motor 41. In this embodiment, the first opening 111 is an air inlet, and the second opening 121 is an air outlet. The heat dissipation fan 50 can drive the external airflow to enter from the first opening 111, and can quickly discharge the airflow from the second opening 121 to increase the flow speed of the airflow, that is, it can improve the heat dissipation effect and heat dissipation efficiency of the motor 41.

[0039] The technical solution of the utility model is to respectively set a first opening 111 and a second opening 121 on the front plate 11 and the rear plate 12 of the installation box 10, install the fixed structure 20 on the rear plate 12, slide the movable cylinder 31 of the movable component 30 on the fixed structure 20, extend from the first opening 111, and be connected with the mounting plate 32 of the movable component 30, the driving mechanism 40 is provided with a motor 41 and a transmission structure 42, the motor 41 is installed on the fixed component, and is connected with the movable cylinder 31 through the transmission structure 42, and the heat dissipation fan 50 is arranged on the installation box 10 to drive the airflow to enter from the first opening 111 and then be discharged from the second opening 121. In this way, the flow of the airflow is accelerated by setting the heat dissipation fan 50, so that after the airflow enters the air duct 13 from the first opening 111, it flows through the motor 41 to take away the heat of the motor 41, and is quickly discharged from the second opening 121, so as to achieve heat dissipation of the motor 41, thereby improving the heat dissipation effect of the motor 41, and further facilitating the improvement of the heat dissipation efficiency of the motor 41.

[0040] In some embodiments, the heat dissipation fan 50 is disposed at the second opening 121. It can be understood that the heat dissipation fan 50 is disposed at the second opening 121, so that after the airflow enters from the first opening 111, it can be quickly discharged from the second opening 121 under the action of the heat dissipation fan 50, so as to increase the flow speed of the airflow, that is, to improve the heat dissipation efficiency of the motor 41. Of course, in other embodiments, the heat dissipation fan 50 can also be disposed at other positions, for example: beside the first opening 111, between the first opening 111 and the second opening 121.

[0041] Furthermore, the heat dissipation fan 50 is arranged outside the installation box 10. That is, the heat dissipation fan 50 is installed outside the installation box 10 to pump out the airflow in the air duct 13 through the second opening 121. In this way, the heat dissipation fan 50 is arranged using the space outside the installation box 10, which is conducive to saving the internal space of the installation box 10 and avoiding interference with the installation and activity of the movable structure, that is, it can reduce the overall size of the installation box 10 and reduce the occupied space. Of course, in other embodiments, the heat dissipation fan 50 can also be installed inside the installation box 10.

[0042] In some embodiments, the fixed structure 20 is made of a heat-conducting material, and the motor 41 is connected to the fixed structure 20 by heat conduction. Specifically, the heat generated by the motor 41 during operation can be absorbed by the fixed structure 20, so that when the airflow flows into the air duct 13 between the first opening 111 and the second opening 121, the motor 41 and the fixed structure 20 can be cooled at the same time, which is equivalent to increasing the heat dissipation area of ​​the motor 41, thereby improving the heat dissipation efficiency of the motor 41. Among them, the material of the fixed structure 20 is at least one of copper, aluminum, aluminum alloy and tungsten.

[0043] Furthermore, the fixing structure 20 includes a fixing base 21, which includes a first plate body 211, a second plate body 212 and two triangular plates 213. The first plate body 211 is installed on the rear plate 12, and a ventilation hole is provided corresponding to the second opening 121. The ventilation hole is connected to the second opening 121. The two triangular plates 213 are arranged on opposite sides of the first plate body 211. The second plate body 212 is installed above the two triangular plates 213 and extends from the first plate body 211 toward the direction of the front plate 11. The motor 41 is installed between the two triangular plates 213.

[0044] Specifically, the fixing seat 21 mainly includes a first plate body 211, a second plate body 212 and two triangular plates 213 which are formed separately and assembled, so that it is convenient to form the first plate body 211, the second plate body 212 and the triangular plates 213, which is conducive to reducing production costs. At the same time, the motor 41 is installed between the two triangular plates 213, so that it is convenient for the motor 41 to conduct heat to the two triangular plates 213, and the channel opening of the first plate body 211 corresponding to the second opening 121 is set, so that the air flow can quickly flow out from the second opening 121, that is, the heat dissipation efficiency of the motor 41 is improved. Of course, in other embodiments, the fixing structure 20 may not be provided with two triangular plates 213, and the motor 41 is installed on the second plate body 212.

[0045] Furthermore, a heat-conducting medium layer is provided between the motor 41 and the two triangular plates 213. Specifically, the heat-conducting medium layer can be provided on the surface of the motor 41, or on the surface of the triangular plate 213. It can be understood that by providing a heat-conducting medium layer, the motor 41 and the triangular plate 213 can be seamlessly fitted when they are thermally connected, so that the heat of the motor 41 can be better transferred to the triangular plate 213, thereby improving the heat dissipation efficiency. Among them, the heat-conducting medium layer can be: thermal grease, thermal silica gel, thermal pad, etc., which is not specifically limited in this application. Of course, in other embodiments, a heat-conducting medium layer may not be provided between the triangular plate 213 and the motor 41.

[0046] In some embodiments, the transmission structure 42 includes a driving gear 421, a driven gear 422 and a transmission chain. The driving gear 421 is sleeved on the rotating shaft of the motor 41, and the driven gear 422 is rotatably installed on the end of the second plate body 212 away from the first plate body 211. The transmission chain is sleeved on the driving gear 421 and the driven gear 422. A fixing part is provided in the movable cylinder 31, and the fixing part is located between the driving gear 421 and the driven gear 422, and the fixing part is fixed to the transmission chain.

[0047] Specifically, when the driving motor 41 drives the driving gear 421 to rotate, the driving gear 421 drives the transmission chain to move, wherein the portion of the transmission chain between the driving gear 421 and the driven gear 422 moves in a straight line along the direction from the driving gear 421 to the driven pulley, thereby driving the fixed part and the movable cylinder 31 to move. By adopting the chain drive mode, the transmission of the movable cylinder 31 can be stable and efficient. Of course, in other embodiments, the transmission structure 42 can also be set as a pulley.

[0048] In some embodiments, the fixed structure 20 also includes a first slide rail 22, which is fixed to the second plate body 212 and extends from the rear plate 12 in the direction of the front plate 11. The movable cylinder 31 is sleeved outside the first slide rail 22, and the inner wall of the movable cylinder 31 corresponds to the position of the first slide rail 22, and the first slide rail 22 is slidably matched with the first slide rail 22.

[0049] Specifically, the first slider is fixed to the inner side of the movable cylinder 31 and is slidably mounted on the first slide rail 22. The mounting plate 32 is located outside the first opening 111. The mounting plate 32 is substantially perpendicular to the first slide rail 22. The side of the mounting plate 32 away from the fixed seat 21 is used to mount the display screen. That is, it is equivalent to using the internal space of the movable cylinder 31 to set the first slide rail 22, which can make the structure of the movable assembly 30 and the fixed structure 20 more compact, and improve the compactness of the fixed structure 20 and the movable assembly 30. Of course, in other embodiments, the first slider is mounted on the outer side of the supporting movable cylinder 31.

[0050] In some embodiments, the fixed structure 20, the movable component 30, the driving mechanism 40 and the heat dissipation fan 50 form an ejection module, the front panel 11 is provided with four first openings 111, the rear panel 12 is provided with four second openings 121, the four first openings 111 and the four second openings 121 are distributed in a matrix, an ejection module is provided in the installation box 10 corresponding to each first opening 111 and second opening 121, and the display ejection mechanism is provided with a heat dissipation fan 50 corresponding to each second opening 121.

[0051] That is, each ejection module can be installed with a display screen, and one display screen ejection mechanism can be installed with four display screens. When assembling the wave display screen on site, the number of display screen ejection mechanisms can be simplified, thereby improving assembly efficiency. At the same time, a heat dissipation fan 50 is provided corresponding to each second opening 121, so that one heat dissipation fan 50 is used to dissipate heat for one motor 41. Compared with the method of dissipating heat for four motors 41 by one heat dissipation fan 50, the heat dissipation efficiency of the motor 41 can be effectively improved. Of course, in other embodiments, only one heat dissipation fan 50 is provided on the rear plate 12.

[0052] In some embodiments, the display screen ejection mechanism further includes a protective cover 60, which is disposed on the side of the rear plate 12 away from the front plate 11, and a plurality of mutually spaced air outlets 61 are disposed on the surface of the protective cover 60. Specifically, the protective cover 60 is disposed on the outside of the four heat dissipation fans 50 to provide protection for the heat dissipation fans 50 and prevent the heat dissipation fans 50 from colliding with external objects and causing damage. Of course, in other embodiments, the display screen ejection mechanism may not be provided with a protective cover 60. Alternatively, a protective cover 60 may be provided for each heat dissipation fan 50.

[0053] The utility model also proposes a wave display screen, which includes a display screen unit 70 and a display screen ejection mechanism. The specific structure of the display screen ejection mechanism refers to the above-mentioned embodiment. Since the wave display screen adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. Among them, the display screen unit 70 is installed on the mounting plate 32 of the display screen ejection mechanism. Optionally, the wave display screen includes a plurality of display screen ejection mechanisms, and a display screen unit 70 is installed on the mounting plate 32 of each display screen ejection mechanism, and all the display screen units 70 together constitute a display screen. When in use, each active component 30 can be controlled to extend and retract while playing the video in a preset manner to achieve a three-dimensional display effect.

[0054] The above are only preferred embodiments of the present invention, and do 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 inventive 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.
