For a better understanding of the present utility model, a driving device, an LED housing assembly, and an LED display device according to embodiments of the present utility model are described in detail with reference to fig. 1 to 10.

Referring to fig. 1 and 2, an embodiment of the present utility model provides a driving device, which includes a housing assembly 1 and a driving assembly 2, wherein the housing assembly 1 includes a first housing 11 and a second housing 12 distributed along a first direction X, the first housing 11 and the second housing 12 are buckled to form an accommodating space, the driving assembly 2 is disposed in the accommodating space, the driving assembly 2 includes a rotating shaft 21, a rotating member 22 and a sliding member 23, one end of the rotating member 22 is fixedly connected to the rotating shaft 21, the other end is movably connected to the sliding member 23, and the sliding member 23 is used for being connected to a driven member. The rotating shaft 21 extends along a first direction X, the first housing 11 and the second housing 12 are respectively provided with an opening K1 corresponding to the rotating shaft 21, the rotating shaft 21 can rotate with its own axis as a rotation center, and the rotating member 22 drives the sliding member 23 to reciprocate along a second direction Y, where the second direction Y intersects with the first direction X.

The driving device in the embodiment of the utility model comprises a shell assembly 1 and a driving assembly 2, wherein the shell assembly 1 comprises a first shell 11 and a second shell 12 which are buckled to form an accommodating space, the driving assembly 2 is arranged in the accommodating space, the driving assembly 2 comprises a rotating shaft 21, a rotating piece 22 and a sliding piece 23, one end of the rotating piece 22 is fixedly connected with the rotating shaft 21, the other end of the rotating piece 22 is movably connected with the sliding piece 23, and the sliding piece 23 is used for being connected with a driven piece. The rotating shaft 21 extends along the first direction X, and the first housing 11 and the second housing 12 are respectively provided with an opening K1 corresponding to the rotating shaft 21, so that the rotating shaft 21 can be driven to rotate through the opening K1 on both the first housing 11 side and the second housing 12 side, and the sliding piece 23 is driven to reciprocate along the second direction Y through the rotating piece 22 fixedly connected to the rotating shaft 21, so that the linear movement of the driven piece is realized, and the double-side driving requirement of the driving device is realized.

It can be understood that the rotating shaft 21 can be manually rotated, for example, a connecting hole can be formed on the rotating shaft 21, so that the rotating shaft 21 can be rotated by connecting a tool such as a hexagonal wrench with the connecting hole during use, and handles can be fixed at two ends of the rotating shaft 21, so that the rotating shaft 21 can be rotated by rotating the handles. The rotation shaft 21 may also be driven by a motor, which may be provided as a stepping motor. In addition, the rotating member 22 and the sliding member 23 may form a crank slider mechanism, so that when the rotating shaft 21 rotates, the sliding member 23 is driven by the rotating member 22 to reciprocate along the second direction Y.

Alternatively, both ends of the rotation shaft 21 in the first direction X may be protruded from the openings K1 of the first and second housings 11 and 12, thereby facilitating the operator to drive the rotation shaft 21 to rotate and simplifying the operation.

In some alternative embodiments, at least one of the first housing 11 and the second housing 12 is provided with a guide groove K2 extending in the second direction Y, and the slider 23 is slidably provided along the guide groove K2, thereby ensuring that the driven member can move linearly in the second direction Y.

Optionally, the sliding member 23 may include a sliding rod 231 and a connecting portion 232 disposed on the sliding rod 231, where the connecting portion 232 is used to connect with a driven member, two ends of the sliding rod 231 along the first direction X protrude from the connecting portion 232 and are slidably disposed along a guiding slot K2, a section of two ends of the sliding rod 231 along the first direction X may be rectangular, trapezoidal, or elliptic, and the guiding slot K2 is matched with an end of the sliding rod 231, so that the sliding rod 231 is limited to rotate by the guiding slot K2, so as to avoid the situation that the sliding member 23 rotates under the driving of the rotating member 22.

In some alternative embodiments, the rotating member 22 is provided with a bar slot extending towards the rotation center, and the sliding member 23 is movably connected with the bar slot, so that the sliding member 23 can be driven to reciprocate along the second direction Y by rotating the rotating member 22 when the length of the rotating member 22 is fixed.

Alternatively, the bar-shaped groove may extend to the end of the rotating member 22 and form an opening at the end of the rotating member 22, thereby facilitating the connection of the sliding member 23 to the bar-shaped groove through the opening to simplify the connection structure of the sliding member 23 and the rotating member 22. In addition, in some other embodiments, the rotating member 22 may be configured as a telescopic structure, that is, the sliding member 23 may be driven by the rotating member 22 to move along the second direction Y.

Considering that in some applications, after the driven member is linearly moved, the driven member is limited in position to prevent the driven member from sliding freely, in order to limit the driven member, in some alternative embodiments, the housing assembly 1 further includes a limiting member 13 sandwiched between the first housing 11 and the second housing 12, and the limiting member 13 is provided with a locking portion 131. The rotation shaft 21 has a degree of freedom of movement in the first direction X, so that the driving assembly 2 is switched between a locked state in which the rotation member 22 is locked to the locking portion 131 and an unlocked state in which the rotation member 22 is disengaged from the locking portion 131.

That is, when the position of the rotating member 22 along the first direction X corresponds to the limiting member 13, the rotating member 22 is locked in the locking portion 131 of the limiting member 13, and the driving assembly 2 is in a locked state, so that the limiting of the sliding member 23 is achieved by limiting the rotation of the rotating shaft 21. When the position of the rotating member 22 along the first direction X is dislocated from the position of the limiting member 13, the rotating member 22 is separated from the locking portion 131 of the limiting member 13, the driving assembly 2 is in an unlocked state, the rotating shaft 21 can rotate along its own axis as a rotation center, so as to realize movement of the sliding member 23, and thus, according to the use requirement, the switching of the driving assembly 2 in the locked state and the unlocked state can be realized by moving the rotating shaft 21 along the first direction X.

Alternatively, the locking portion 131 may be provided as a locking hole matching the shape of the rotating member 22, and the locking portion 131 may be provided as a magnetic absorbing member capable of achieving position locking of the rotating member 22 when the rotating member 22 moves to the position limiter 13 in the first direction X, so as to limit the rotational degree of freedom of the rotating member 22.

It can be understood that, since the two ends of the rotating shaft 21 along the first direction X are protruded from the first housing 11 and the second housing 12, the positions of the rotating shaft 21 along the first direction X can be adjusted from the first housing 11 side and the second housing 12 side, so as to realize the limitation and the driving of the sliding member 23 on both sides.

Specifically, taking the example of pressing the rotating shaft 21 to adjust the position of the rotating shaft 21 along the first direction X, when the driving assembly 2 is in the locked state, referring to fig. 3 and 4, fig. 3 is a schematic diagram of pressing the rotating shaft 21 from the second housing 12 side, and when the rotating shaft 21 is pressed from the second housing 12 side through the opening K1, the rotating member 22 on the rotating shaft 21 moves along the first direction X toward the first housing 11, so that the rotating member 22 is separated from the locking portion 131, and the driving assembly 2 is switched to the unlocked state. Fig. 4 is a schematic view of the rotating shaft 21 being pressed from the first housing 11 side, when the rotating shaft 21 is pressed from the first housing 11 side through the opening K1, the rotating member 22 on the rotating shaft 21 moves toward the second housing 12 in the first direction X, so that the rotating member 22 is disengaged from the locking portion 131 to switch the driving assembly 2 to the unlocked state. Therefore, the state of the driving assembly 2 can be switched from both sides, and the driving assembly can be operated from any side in actual use, so that the applicability of the driving device is improved.

Referring to fig. 5 to 9, since the driven member often has only a few specific locking positions in actual use, in order to achieve the limitation of the driven member at the specific positions, in some alternative embodiments, the locking portion 131 includes a first locking position 131a and a second locking position 131b, and the first locking position 131a and the second locking position 131b are distributed in a central symmetry with respect to the rotating shaft 21. The locking state includes a first sub-state in which the rotating member 22 is clamped in the first locking position 131a, the sliding member 23 is accommodated in the housing assembly 1, and a second sub-state in which the rotating member 22 is clamped in the second locking position 131b, and the sliding member 23 is at least partially protruded from the housing assembly 1 along the second direction Y.

That is, when the rotation shaft 21 rotates to a predetermined angle, the locking is performed on the first locking position 131a and the second locking position 131b, and when the rotation shaft 21 rotates to other angles, the locking of the rotation shaft 21 is not performed. When the rotating member 22 is fastened on the first rotation position, the sliding member 23 is retracted in the housing assembly 1, and when the rotating member 22 is fastened on the second rotation position, the sliding member 23 protrudes out of the housing assembly 1, so that the limit of the driven member at the protruding position and the retracting position can be realized by arranging the first locking position 131a and the second locking position 131b on the limit portion.

It will be appreciated that in some other embodiments, the number of locking bits may be more than three, and the plurality of locking bits are distributed symmetrically with respect to the rotation shaft 21, where each locking bit corresponds to the protruding distance of the sliding member 23 along the second direction Y with respect to the housing assembly 1, so that the multi-stage limitation of the driven member can be formed by increasing the number of locking bits.

For convenience of description, the following description will be given by taking the example in which the locking portion 131 includes the first locking bit 131a and the second locking bit 131b.

Referring to fig. 10, in some alternative embodiments, in the unlocked state, the rotating member 22 at least partially extends into one of the first housing 11 and the second housing 12, a side surface of the first housing 11 facing the limiting member 13 is provided with a first rotating groove 111, the first rotating groove 111 extends along a rotating path of the rotating member 22, an orthographic projection on the limiting member 13 covers the first locking position 131a and the second locking position 131b, and/or a side surface of the second housing 12 facing the limiting member 13 is provided with a second rotating groove 121, the second rotating groove 121 extends along the rotating path of the rotating member 22, and an orthographic projection on the limiting member 13 covers the first locking position 131a and the second locking position 131b. That is, by providing the first rotation groove 111 on the first housing 11 and/or providing the second rotation groove 121 on the second housing 12, the rotating member 22 can be pressed into the first rotation groove 111 or the second rotation groove 121 to rotate when the rotating shaft 21 is moved in the first direction X by both sides, thereby guiding the rotation of the rotating member through the first rotation groove 111 and the second rotation groove 121, and simplifying the operation steps of the driving device.

It can be understood that, taking the first rotating groove 111 as an example, the included angle between the two side edges of the first rotating groove 111 in the extending direction and the rotating shaft 21 is equal to the included angle between the first locking position 131a and the second locking position 131b and the rotating shaft 21, so that when the first sub-state is switched to the second sub-state, the rotating member 22 can be directly rotated from one side edge to the other side edge of the first rotating groove 111, thereby further simplifying the operation steps of the driving device.

Referring to fig. 1 to 10, in order to more conveniently adjust the position of the rotating shaft 21 along the first direction X, in some alternative embodiments, the driving device further includes elastic members 3 disposed in pairs, one of the elastic members 3 disposed in pairs is sandwiched between the rotating member 22 and the first housing 11 along the first direction X, and the other is sandwiched between the rotating member 22 and the second housing 12 along the first direction X. In the locked state, the elastic members 3 are all in an original length state, and in the unlocked state, one of the elastic members 3 provided in pairs is in an elastically deformed state. Therefore, after the driving assembly 2 is switched to the unlocking state by pressing the rotating shaft 21, the rotating shaft 21 can automatically move back to the initial position under the action of the elastic piece 3 by stopping applying the pressing force, namely, the rotating piece 22 and the locking part 131 are clamped in the locking state, so that the driven piece can be automatically limited.

Specifically, the elastic members 3 disposed in pairs may include a first elastic portion 31 and a second elastic portion 32, and by providing the first elastic portion 31 and the second elastic portion 32, the first elastic portion 31 and the second elastic portion 32 may cooperate to ensure that the rotating member 22 can suspend in the locking position, i.e. the position of the rotating member 22 corresponding to the limiting member 13 along the first direction X. In the unlocked state, one of the first elastic portion 31 and the second elastic portion 32 is compressed, and the other is in a relaxed state, so that when the pressing force is stopped, the first elastic portion 31 and the second elastic portion 32 move back to the locking position under the action of the restoring force, and automatic limiting of the driven piece is achieved.

It should be noted that, when the first direction X is the vertical direction, that is, the driving assembly 2 is in the locked state, the elastic member 3 may not be in an original length state in consideration of the self weight of the driving assembly 2. Wherein the elastic member 3 is arranged such that the driving assembly 2 can be suspended in the locking position in the first direction X by the action of the elastic member 3 after stopping the application of the pressing force.

Since the rotating shaft 21 can be driven from two sides, in order to more reliably realize automatic limiting of the driven member, in some alternative embodiments, the rotating members 22 are symmetrically disposed along the first direction X in pairs, and abut against the first housing 11 and the second housing 12. The first elastic part 31 and the second elastic part 32 are symmetrically arranged on two sides of the rotating piece 22, namely the action points of the elastic pieces 3 on the two sides on the rotating piece 22 are positioned on the same straight line, so that the situation that the rotating piece 22 is overturned due to moment is avoided, and the reliability of the driving device is ensured.

Alternatively, the elastic member 3 may be provided as a spring, or may be provided as a structural member made of other elastic materials, and when the elastic member 3 is provided as a spring, the elastic member 3 may be sleeved on the outer circumference of the rotating shaft 21, so as to simplify the structure of the driving device.

The operation steps of the driving device in the embodiment of the present utility model will be described below with reference to fig. 1 to 10, taking driving from the first housing 11 side as an example.

The first step, the rotating shaft 21 is pressed, so that the rotating piece 22 on the rotating shaft 21 is separated from the first locking position 131a on the limiting piece 13 and at least partially stretches into the second rotating groove 121, the driving assembly 2 is switched to an unlocking state, and the elastic part is in an elastic deformation state;

the second step, the rotating shaft 21 is rotated, the upper rotating piece 22 is rotated from one side edge to the other side edge of the second rotating groove 121, and the sliding piece 23 is driven by the rotating piece 22 to move along the second direction Y and at least partially protrudes out of the shell component 1;

third, the pressing of the rotating shaft 21 is stopped, the driving assembly 2 moves toward the first housing 11 along the first direction X under the action of the elastic portion, and is automatically locked on the second locking position 131b of the limiting member 13, and the elastic portion is in the original length state.

The embodiment of the utility model also provides an LED box assembly, which comprises a first plug connector, a second plug connector and a driving device, wherein the driving device is the driving device of any embodiment, one of the first plug connector and the second plug connector is connected to a sliding part 23 of the driving device, and the driving device is used for driving the first plug connector to be connected with or separated from the second plug connector. The first plug connector can be arranged as a male end, the second plug connector can be arranged as a female end, and the driving device can be arranged as the driving device in the embodiment, so that the double-side driving requirement can be met, and the connection and the separation of the male end and the female end are more convenient.

In addition, since the driving assembly 2 can include a locking state and an unlocking device, by arranging the driving device in the embodiment of the utility model, the male end or the female end can be prevented from falling under the influence of gravity or other acting forces, so that the second plug connector can be effectively plugged and matched with the first plug connector, virtual connection is prevented, looseness is not easy to occur, and good contact effect is ensured.
