[0007] According to one aspect of the present application, the floating component has an arcuate surface, and the distance between each point on the arcuate surface and the center point is equal. The floating component abuts against one side of the lifting component along the first direction through the arcuate surface.

[0011] According to one aspect of the present application, it also includes an elastic component, which includes a first elastic part, and the first elastic part is arranged between the sliding member and the shell along the second direction; the elastic component also includes a second elastic part, and the second elastic part is arranged between the lifting component and the shell along the first direction.

[0012] According to one aspect of the present application, the pressing assembly also includes pressing members used in pairs. In the sunken state, at least one of the pressing members protrudes from the shell along the first direction; the pressing member has the freedom of movement along the first direction and drives the sliding member to move along the second direction.

[0013] According to one aspect of the present application, the contact surface between the pressing member and the sliding member is set as an inclined surface, and the inclined surface is set at an angle to the first direction and the second direction; or, the sliding member includes a cam rod and a transmission rod that are hinged to each other, and the transmission rod is slidingly connected to the guide groove, and the cam rod is rotatably connected to the shell and abuts against one side of the pressing member along the first direction, and the pressing member can drive the transmission rod to move along the second direction through the cam rod.

[0014] On the other hand, an embodiment of the present application provides an LED box assembly, including a first connector, a second connector, and a driving device, wherein the driving device is the driving device described in any of the above embodiments, and one of the first connector and the second connector is connected to the lifting assembly of the driving device, and the driving device is used to drive the first connector and the second connector to connect or separate.

The spacing between the paired guide grooves along a second direction gradually increases from the first end to the second end of the guide groove. The paired pressing rods are each slidably connected to their corresponding guide grooves. Therefore, when pressing on one side, the sliding member on the one side slides along the guide groove and drives the floating assembly to rotate about the center point, while the floating assembly does not move in the first direction. This ensures that the lifting assembly remains completely stationary in the first direction during unilateral pressing. When pressing on both sides, the sliding members on the paired sides slide along the guide groove, which restricts the rotation of the floating assembly. This allows the floating assembly to move in the first direction under the action of the paired sliding members and lift the pressing assembly. Therefore, the drive device in the embodiment of the present application only moves the lifting assembly during bilateral pressing, while ensuring that the lifting assembly remains stationary during unilateral pressing, thereby improving the reliability of the drive device.

[0036] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessary ambiguity in the present application; and, for clarity, the sizes of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0037] In the description of this application, it should be noted that, unless otherwise specified, "plurality" means more than two; terms such as "upper," "lower," "left," "right," "inner," and "outer" indicating directions or positional relationships are merely for the purpose of facilitating the description of this application and simplifying the description. They do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the embodiments of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0039] In order to better understand the present invention, Figures 1 to 15 The driving device, LED box assembly and LED display device according to the embodiments of the present application are described in detail.

[0040] See also Figures 1 to 3The present application provides a driving device, including a lifting component 1, a floating component 2 and a pressing component 3. The lifting component 1 has a degree of freedom of movement along a first direction Y. The lifting component 1 is used to connect with a driven component. The floating component 2 is connected to the lifting component 1. The floating component 2 is provided with a pair of guide grooves 21. Each guide groove 21 includes a first end 211 and a second end 212 opposite to each other along the first direction Y. The first ends 211 of the paired guide grooves 21 converge at a center point. The floating component 2 can be rotated around the center point. From the first end 211 to the second end 212 of the guide groove 21, the spacing of the paired guide grooves 21 along the second direction X gradually increases. The first direction Y intersects with the second direction X. The pressing component 3 includes a pair of sliding members 31. The paired sliding members 31 can move toward or away from each other along the second direction X, and are both slidably connected to their corresponding guide grooves 21.

[0041] In the drive device of the embodiment of the present application, when one of the paired sliding members 31 moves in the second direction X, the floating assembly 2 rotates about its center point, but does not move in the first direction Y. This ensures that the lifting assembly 1 remains completely stationary in the first direction Y during unilateral pressure. When the two paired sliding members 31 move toward or away from each other, they restrict the rotation of the floating assembly 2, allowing the floating assembly 2 to move in the first direction Y under the action of the paired sliding members 31 and lift the pressing assembly. Therefore, the drive device of the embodiment of the present application moves the lifting assembly 1 only during bilateral pressure, and maintains the lifting assembly 1 stationary during unilateral pressure, thereby improving the reliability of the drive device.

[0042] For ease of description, the paired sliding members 31 are defined as a first sliding member 31a and a second sliding member 31b, and the paired guide grooves 21 are defined as a first guide groove 21a and a second guide groove 21b. It is understood that because the first ends 211 of the paired guide grooves 21 converge at a central point and are capable of rotating about the central point, for example, when only the first sliding member 31a is pressed, the first sliding member 31a slides along the first guide groove 21a, while the second sliding member 31b remains in the first end 211 of the second guide groove 21b. Consequently, the floating assembly 2 rotates under the action of the first sliding member 31a, with the first end 211 of the second guide groove 21b, where the second sliding member 31b is located, serving as a fulcrum. This ensures that the lifting assembly 1 remains stationary when pressed from one side, thereby improving the reliability of the drive device.

[0043] Among them, the spacing of the guide grooves 21 used in pairs along the second direction X gradually increases from the first end 211 to the second end 212 of the guide groove 21, which means that the guide grooves 21 are set as inclined grooves, and in the second direction X, the guide grooves 21 set in pairs are respectively inclined to both sides, so that when the sliding members 31 approach or move away from each other along the second direction X, the floating assembly 2 can move along the first direction Y under the drive of the sliding member 31, thereby driving the jacking assembly 1 connected to the floating assembly 2 to move along the first direction Y, thereby realizing the lifting and lowering of the driven member.

[0044] Optionally, the first guide groove 21a and the second guide groove 21b can be respectively arranged on the two side surfaces of the floating component 2 along the third direction Z, and the first direction Y, the second direction X and the third direction Z are arranged perpendicularly in pairs. The first sliding member 31a and the second sliding member 31b respectively extend to the two side surfaces of the floating component 2 along the third direction Z, and are respectively slidably arranged along the first guide groove 21a and the second guide groove 21b, so as to avoid mutual interference between the moving paths of the first sliding member 31a and the second sliding member 31b, thereby ensuring the reliability of the driving device.

[0045] In some optional embodiments, the first slider 31a may include a plurality of first sub-sliders spaced apart along the third direction Z and a first connecting portion for connecting the first sub-sliders. Similarly, the second slider 31b may include a plurality of second sub-sliders spaced apart along the third direction Z and a second connecting portion for connecting the second sub-sliders. The number of floating assemblies 2 is equal to the number of first sub-sliders, and the corresponding first sub-sliders and second sub-sliders are slidably connected to the same floating assembly 2. By configuring the first slider 31a as a plurality of sub-sliders, the sub-sliders can be linked via the connecting portions. Therefore, when pressed, the plurality of first and second sub-sliders can be driven simultaneously, thereby improving the efficiency and safety of the driving device.

[0046] It can be understood that the floating component 2 can be directly rotatably connected to one side of the pressing component. In order to save space in the driving device, the floating component 2 can be abutted against one side of the pressing component along the first direction Y, so that when the floating component 2 moves along the first direction Y, it can push out the lifting component 1 along the first direction Y to realize the lifting and lowering of the driven part.

[0047] See also Figures 1 to 3When the floating assembly 2 abuts against one side of the lifting assembly 1 along the first direction Y, in order to prevent the floating assembly 2 from rotating under unilateral pressure and thereby lifting the lifting assembly 1, in some optional embodiments, the floating assembly 2 has a curved surface, with each point on the curved surface being equidistant from the center point. The floating assembly 2 abuts against the one side of the lifting assembly 1 along the first direction Y via the curved surface. By configuring the surface of the floating assembly 2 facing the lifting assembly 1 as a curved surface, the distance between the center point of the floating assembly 2 and the lifting assembly 1 remains unchanged during the rotation of the floating assembly 2, thereby ensuring that the lifting assembly 1 can remain stationary during the unilateral pressure.

[0048] Alternatively, the floating assembly 2 may be configured as a fan-shaped structure extending radially from a central point. The surface of the fan-shaped structure facing the lifting assembly 1 is configured as an arcuate surface, and the first guide groove 21a and the second guide groove 21b extend along the two edges of the fan-shaped structure, respectively. By configuring the floating assembly 2 as a fan-shaped structure, the space occupied by the floating assembly 2 during rotation is further reduced, while also facilitating the arrangement of the first guide groove 21a and the second guide groove 21b.

[0049] In some optional embodiments, the length of the guide groove 21 is greater than or equal to the maximum movement distance of the sliding member 31 along the second direction X, so that during unilateral pressing, even if the sliding member 31 moves to the maximum position, the floating component 2 will not rotate to the extreme angle, or will just rotate to the extreme angle, thereby avoiding the situation where the sliding member 31 drives the floating component 2 to move along the first direction Y during unilateral pressing.

[0050] It is understood that because the length of the guide slot 21 is greater than the preset travel distance of the slider 31 along the second direction X, after pressing from one side, the slider 31 will have a certain amount of idle travel when pressing from the other side, which may affect the efficiency of the drive device. Alternatively, the length of the guide slot 21 can be made equal to the preset travel distance of the slider 31 along the second direction X. This allows the slider 31 to reciprocate between the first end 211 and the second end 212 of the guide slot 21, thereby ensuring the reliability of the drive device while improving its efficiency.

[0051] See also Figure 4To further prevent the sliding member 31 from causing the floating assembly 2 to move along the first direction Y when pressed from one side, in some optional embodiments, a slideway 11 is provided on the lifting assembly 1. The slideway 11 extends along the second direction X, and the floating assembly 2 is slidably connected to the slideway 11. Providing the slideway 11 on the lifting assembly 1 allows, on the one hand, the floating assembly 2 to be limited in position along the third direction Z by the slideway 11, thereby preventing the floating assembly 2 from twisting or even falling off under the action of the pressing assembly 3. On the other hand, after being pressed from one side by the sliding member 31, the floating assembly 2 can not only rotate about its center point but also move a certain distance along the second direction X relative to the lifting assembly 1, thereby ensuring that the floating assembly 2 has freedom of movement along the second direction X.

[0052] It can be understood that when the slide 11 is provided on the jacking component 1, the length of the guide groove 21 may be less than the maximum moving distance of the sliding member 31 along the second direction X, that is, when pressed on one side, when the sliding member 31 moves to the end of the guide groove 21, that is, when the floating component 2 rotates to the extreme angle, the floating component 2 can continue to slide relative to the jacking component 1 along the second direction X under the drive of the sliding member 31 until the sliding member 31 reaches the maximum moving distance, and in this process will not drive the floating component 2 to move along the first direction Y, thereby further ensuring that the jacking component 1 is completely still when pressed on one side.

[0053] Therefore, when the floating assembly 2 is slidably connected to the slideway 11 of the lifting assembly 1, the length of the guide groove 21 can be adjusted according to the specific space of the drive device. This is not specifically limited in this application. However, for ease of description, the following example assumes that the length of the guide groove 21 is equal to the maximum travel distance of the slider 31 along the second direction X, that is, the slider 31 slides back and forth between the first end 211 and the second end 212 of the guide groove 21.

[0054] See also Figures 5 to 14 In some optional embodiments, the drive device further includes a housing 4 having an inner cavity, in which the lifting assembly 1, the floating assembly 2, and the pressing assembly 3 are disposed. The drive device includes a sinking state and a lifting state. In the sinking state, at least one sliding member 31 is located at the first end 211 of the guide groove 21, and the driven member is accommodated in the housing 4. In the lifting state, the paired sliding members 31 are both located at the second end 212 of the guide groove 21, and the driven member at least partially protrudes from the housing 4 along the first direction Y. When the sliding members 31 on both sides approach or move away from each other along the second direction X, since the positions of the sliding members 31 along the first direction Y are fixed, when the sliding members 31 both move from the first end 211 of the guide groove 21 to the second end 212 of the guide groove 21, they can drive the floating assembly 2 to move along the first direction Y, and the passive lifting assembly 1 can lift the driven member.

[0055] Optionally, the shell 4 may include a top plate and a first guide rail arranged on one side of the top plate, the top plate is provided with an opening corresponding to the driven part, the first guide rail is extended along the first direction Y, and the jacking assembly 1 is slidably connected to the first guide rail, thereby ensuring that after pressing on both sides, the jacking assembly 1 can move along the first direction Y under the constraint of the first guide rail and allow the driven part to pass through the opening and at least partially protrude from the shell 4.

[0056] The sinking state further includes a first sub-state and a second sub-state. In the first sub-state, the pressing rods used in pairs are both located at the first end 211 of the guide groove 21 corresponding to themselves. In the second sub-state, one of the two sliding members 31 used in pairs is located at the first end 211 of the guide groove 21, and the other sliding member 31 is located at the second end 212 of the other guide groove 21. Specifically, Figures 1 to 6 is a schematic diagram of the driving device in the first sub-state, Figures 7 to 10 is a schematic diagram of the driving device in the second sub-state, Figures 11 to 14 This is a schematic diagram of the drive device in the jacking state.

[0057] See also Figure 5 and Figure 6 、 Figure 9 and Figure 10 as well as Figure 13 and Figure 14 In some optional embodiments, the drive device further includes an elastic component 5, which includes a first elastic portion 51 disposed between the sliding member 31 and the housing 4 along the second direction X. The elastic component 5 further includes a second elastic portion 52 disposed between the lifting component 1 and the housing 4 along the first direction Y. The provision of the first elastic portion 51 and the second elastic portion 52 facilitates switching between the lowered state and the raised state.

[0058] Optionally, in the first sub-state, the elastic component 5 is in its original length, and in the lifted state, the elastic component 5 is in an elastically deformed state. For example, in the case of an elastic component 5 comprising a first elastic portion 51 and a second elastic portion 52, when unilateral pressure is applied, upon application of the pressing force, the slider 31 moves in the second direction X under the action of the pressing force, stretching or compressing the first elastic portion 51, causing the floating component 2 to rotate. Upon cessation of the pressing force, the slider 31 returns to its original position under the action of the first elastic portion 51. In the case of bilateral pressure, upon application of the pressing force, the sliders 31 on both sides move in the second direction X under the action of the pressing force, stretching or compressing the first elastic portion 51. The floating component 2 moves in the first direction Y and compresses the second elastic portion 52 via the lifting component 1. Upon cessation of the pressing force, the slider 31 returns to its original position under the combined action of the first elastic portion 51 and the second elastic portion 52, thereby simplifying the operation of the drive device.

[0059] To simplify the structure of the drive device, in some optional embodiments, the pressing assembly 3 further includes a pair of pressing members 32. In the sunken state, at least one pressing member 32 protrudes from the housing 4 in the first direction Y. The pressing member 32 has freedom of movement along the first direction Y. The pressing members 32 are provided in a one-to-one correspondence with the sliding member 31 and can drive the sliding member 31 to move in the second direction X. By having the pressing members 32 protrude from the housing 4 in the first direction Y, it is easier for the operator to move the pressing members 32 in the first direction Y, thereby driving the sliding member 31 to move in the second direction X.

[0060] It can be understood that the pressing members 32 arranged in pairs can be defined as a first pressing member 32a and a second pressing member 32b. The one-to-one correspondence between the pressing members 32 and the sliding members 31 means that the first pressing member 32a is connected to the first sliding member 31a, and the second pressing member 32b is connected to the second sliding member 31b. By making the pressing members 32 correspond to the sliding members 31 one by one, the separate control of the first sliding member 31a and the second sliding member 31b is achieved, so as to realize single-sided pressing and double-sided pressing of the driving device.

[0061] Optionally, the shell 4 also includes a base arranged opposite to the top plate, and a second guide rail extending along the second direction X may be provided on the base. The sliding member 31 may be provided as an L-shaped rod, that is, the sliding member 31 includes a first sub-portion and a second sub-portion formed with an angle, the first sub-portion extends along the second direction X and is slidably connected to the second guide rail, and the second sub-portion extends along the first direction Y and is slidably connected to the guide groove 21, so that the first sub-portion can be limited by the second guide rail to ensure that the sliding member 31 can be moved along the second direction X.

[0062] See also Figures 1 to 14 To enable the sliding member 31 to move along the second direction X under the action of the pressing member 32, in some optional embodiments, the contact surface between the pressing member 32 and the sliding member 31 is configured as an inclined surface, and the inclined surface is configured to form an angle with the first direction Y and the second direction X. By configuring the contact surface between the pressing member 32 and the sliding member 31 as an inclined surface, when the pressing member 32 is moved along the first direction Y, the sliding member 31 can be driven to move along the second direction X.

[0063] See also Figure 15In some other embodiments, the sliding member 31 includes a hinged cam rod 311 and a transmission rod 312. The cam rod 311 is rotatably connected to the housing 4 and abuts against one side of the pressing member 32 along the first direction Y. The pressing member 32 can drive the transmission rod 312 to move along the second direction X through the cam rod 311. By configuring the sliding member 31 as a hinged cam rod 311 and a transmission rod 312, when the pressing member 32 is moved along the first direction Y, the cam rod 311 is driven by the pressing member 32 to rotate, and drives the transmission rod 312 connected thereto to move along the second direction X, thereby realizing the driving device.

[0064] An embodiment of the present application also provides an LED box assembly, including a first connector, a second connector, and a driving device, wherein the driving device is the driving device of any of the above embodiments, and one of the first connector and the second connector is connected to the lifting assembly 1 of the driving device, and the driving device is used to drive the first connector and the second connector to connect or separate.

[0065] Optionally, the first connector can be set as a pin, and the second connector can be set as a socket. The first connector is connected to the lifting assembly 1, and an opening corresponding to the pin is provided on the shell 4. Therefore, the first connector can be protruded relative to the shell 4 under the drive of the driving device and connected with the second connector.
