[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0034] It should be understood that when the terms "first," "second," etc. are used in the claims, specification, and drawings of this application, they are only used to distinguish different objects, rather than to describe a specific order. The terms "comprise" and "comprising" used in the specification and claims of this application indicate the presence of the described features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof.

[0035] See also Figure 1As shown, an embodiment of the present application discloses a cover moving device, comprising: a drive unit 1, a connecting rod 13, a reversing unit 2, a transmission unit 3, a speed unit 4 and a cover 6. The drive unit 1 is connected to the connecting rod 13, and the drive unit 1 is suitable for outputting a driving force to the connecting rod 13. The connecting rod 13 extends along a first direction, and the connecting rod 13 is suitable for transmitting the driving force to the reversing unit 2 during rotation. The reversing unit 2 is connected to the connecting rod 13, and the reversing unit 2 is suitable for converting the transmission direction of the driving force from the first direction to the second direction. The speed unit 4 is connected to the reversing unit 2 through the transmission unit 3, and the transmission unit 3 is suitable for causing the speed unit 4 to move along the second direction based on the driving force. The cover 6 is connected to the speed unit 4, and the cover 6 is suitable for moving along the second direction driven by the speed unit 4.

[0036] In this embodiment, the connecting rod 13, the reversing unit 2, the transmission unit 3, and the speed-doubling unit 4 are each provided in two groups, and each group of the connecting rod 13, the reversing unit 2, the transmission unit 3, and the speed-doubling unit 4 is symmetrically arranged along the axis of the cover plate 6, and the two groups of speed-doubling units 4 are respectively connected to the two sides of the cover plate 6. The first direction is a direction parallel to the central axis of the drive unit, and the first direction is perpendicular to the second direction.

[0037] It should be noted that the present application does not limit the specific shape and material of the connecting rod 13, and it can be reasonably selected and set according to actual needs, as long as it can achieve the purpose of transmitting the driving force to the reversing unit 2. In addition, by setting the speed unit 4, a longer movement stroke of the cover plate 6 can be achieved within a limited installation space, which can greatly save installation space. The specific structure of the speed unit 4 can be reasonably selected and set according to actual needs.

[0038] The arrangement of the drive unit 1, the reversing unit 2, and the transmission unit 3 makes the conveying driving force more reliable, and the arrangement of the speed-multiplying unit 4 makes the movement speed of the cover plate 6 faster, thereby improving the transmission effect of the cover plate 6. The movement of the cover plate 6 is driven by two sets of speed-multiplying units 4, making the movement of the cover plate 6 more stable.

[0039] The above components are described in detail below.

[0040] See also Figure 2 、 Figure 3 Combined with Figure 6 As shown, the driving unit 1 includes a motor 11 and a reduction gearbox 12 .

[0041] In this embodiment, the motor 11 is connected to the connecting rod 13 via the reduction gear box 12 , and the reduction gear box 12 is suitable for reducing the power delivered by the motor 11 to form the driving force.

[0042] In this embodiment, there are two reduction gearboxes 12, and the two reduction gearboxes 12 are respectively connected to the two output ends of the motor 11. When the motor 11 is turned on, the driving forces output by the two reduction gearboxes 12 have the same speed and opposite directions. Driven by the reduction gearboxes 12, the output speeds of the two connecting rods 13 are the same and the directions are opposite. Driven by the connecting rods 13, the two reversing units 2 can output two forces with the same speed and the same direction in the second direction. The two sets of transmission units 3 and the speed-doubling unit 4 have the same movement direction and the same speed. Therefore, by setting up two reduction gearboxes 12, the driving force can be output more stably.

[0043] It should be noted that the present application does not limit the specific structure of the drive unit 1, and it can be reasonably selected and configured according to actual needs. It can also be implemented by connecting two output shafts in parallel or in series with one motor, as long as it can achieve the purpose of outputting driving force. The drive unit can be implemented by a dual-output reduction motor.

[0044] See also Figure 2 、 Figure 8 Combined with Figure 9 As shown, the reversing unit 2 includes a reversing element 21 .

[0045] In this embodiment, the reversing member 21 includes a first gear shaft, a second gear shaft, a first connecting end, a second connecting end 211, and a third connecting end 212. The first connecting end extends along the first direction, the second connecting end 211 extends along the second direction, and the third connecting end 212 extends along the first direction. The first connecting end is connected to the connecting rod 13, and the second connecting end 211 is connected to the transmission unit 3.

[0046] Also, see Figure 9 The first gear shaft includes: a first gear 213 and an input shaft, and the second gear shaft includes: a second gear 214 and an output shaft. The first gear 213 is sleeved on the outside of the input shaft, and the second gear 214 is sleeved on the outside of the first end of the output shaft. The first gear 213 and the second gear 214 are engaged with each other. The first end of the input shaft is connected to the first connecting end, the second end of the input shaft is connected to the third connecting end 212, and the second end of the output shaft is connected to the second connecting end 211. The second end of the input shaft is the end away from the connecting rod, and the second end of the output shaft is the end close to the transmission unit 3.

[0047] In addition, the reversing unit 2 can be implemented by a T-type commutator. The second direction is a direction parallel to the output shaft and is a direction in which the driving force is transmitted from the transmission unit 3 along the second connection end 211 .

[0048] The third connection end 212 is connected to a rocking member, and manually rotating the rocking member can drive the third connection end 212 to rotate. In the absence of power, the rocking member can be manually or mechanically rotated, causing the third connection end to drive the connecting rod 13 and transmission unit 3 connected thereto to move, further driving the drive unit 1 to move. This allows the cover moving device to function normally even without power, making the cover moving device more flexible in operation. It should be noted that this application does not limit the specific structure of the rocking member, and it can be reasonably configured according to actual needs.

[0049] The arrangement of the first and second gear shafts makes the diversion and transmission of driving force more precise, reliable, and synchronized, improving the stability of the cover moving device and reducing space usage. The arrangement of the third connection end 212 allows the cover moving device to open and close the cover 6 even in emergency situations, without being restricted by power supply. The third connection end 212 is located on one side, making it easier for the operator to operate.

[0050] See also Figure 3 、 Figure 4 Combined with Figure 8 As shown, the transmission unit 3 includes a transmission rod 31 and a sliding member 32 .

[0051] The transmission rod 31 is connected to the second connection end 211, and the transmission rod 31 extends along the second direction. The sliding member 32 is sleeved outside the transmission rod 31. The transmission rod 31 drives the sliding member 32 to move on the transmission rod 31 based on the driving force, and the sliding member 32 is fixedly connected to the speed unit 4.

[0052] The transmission rod 31 rotates in the second direction under the drive of the reversing member 21 , and the sliding member 32 can move linearly on the transmission rod 31 along the second direction under the drive of the transmission rod 31 .

[0053] The transmission unit 3 can be realized by a screw rod and a nut, and the screw rod and the nut can be self-locking in the absence of a driving force, further enhancing the reliability and safety of the cover moving device.

[0054] It should be noted that the present application does not limit the specific structure of the transmission unit 3, which can be reasonably selected and set according to actual needs, or it can be realized by a combination of a worm gear and a rack, as long as it can achieve the purpose of converting the rotational power transmitted by the reversing unit 2 into linear power.

[0055] See also Figure 4 and Figure 8 As shown, in this embodiment, the speed unit 4 includes: a fixed rack 41, a moving plate 42 and a moving rack 43.

[0056] The movable plate 42 is provided with a gear transmission member 421. The movable plate 42 has a first surface 422, a second surface, and a third surface 423. The first surface 422 and the second surface are parallel, the third surface 423 is perpendicular to the first surface 422, and the third surface 423 is fixedly connected to the sliding member 32. The gear transmission member 421 extends out from the first surface 422 and the second surface.

[0057] In addition, the fixed rack 41 is on the same side as the first surface 422 and meshes with the gear of the gear transmission member 421 extending from the first surface 422. The movable rack 43 is on the same side as the second surface and meshes with the gear of the gear transmission member 421 extending from the second surface.

[0058] When the driving unit 1 outputs the driving force, the sliding member 32 will drive the movable plate 42 to move along the second direction. Since the gear of the gear transmission member 421 extending from the first surface 422 is engaged with the fixed rack 41, the gear transmission member 421 will be driven to rotate. And the movable rack 43 is engaged with the gear extending from the second surface of the gear transmission member 421, so the rotation of the gear transmission member 421 will drive the movable rack 43 to move along the second direction. During the movement of the speed unit 4, the movement distance of the movable rack 43 is twice the movement distance of the movable plate 42. And the movable rack 43 is connected to the cover plate 6 through the connecting plate 14. When the movable rack 43 moves, it can drive the cover plate 6 to move along the second direction, and the movement distance of the cover plate 6 is twice that of the sliding member 32.

[0059] Further, see Figure 5 Combined with Figure 8 As shown, the cover moving device further includes auxiliary wheels 9 .

[0060] A plurality of auxiliary wheels 9 are provided between the movable plate 42 and the protective frame 7 and between the movable plate 42 and the connecting plate 14. The auxiliary wheels 9 are detachably connected to the movable plate 42. The auxiliary wheels 9 are adapted to support and reduce friction when the movable plate 42 moves relative to the protective frame 7 and the connecting plate 14.

[0061] In this embodiment, see Figure 1 Combined with Figure 6 As shown, the cover moving device further includes a protection frame 7 .

[0062] The protective frame 7 is suitable for protecting the drive unit 1, the connecting rod 13, the reversing unit 2, the transmission unit 3 and the speed-doubling unit 4. The protective frame 7 is connected to the drive unit 1, the connecting rod 13, the reversing unit 2, the transmission unit 3 and the speed-doubling unit 4 through a plurality of fixing parts, so that the cover moving device can be firmly mounted on the protective frame 7, ensuring that the cover moving device can operate stably. Among them, the fixed rack 41 is fixedly connected to the protective frame 7 to ensure the operation of the cover moving device. In addition, the protective frame 7 is also provided with a plurality of mounting holes, which are used for the connection between the protective frame 7 and the vehicle body or the box body, so that the cover moving device can be firmly mounted on the vehicle body or the box body.

[0063] It should be noted that the present application does not limit the specific structure and material of the protective frame 7, and it can be reasonably selected and set according to actual needs.

[0064] Furthermore, the cover moving device further includes a control unit.

[0065] The control unit is connected to the driving unit 1 , and is adapted to start or stop the driving unit 1 from outputting the driving force, or to change the output direction of the driving force.

[0066] It should be noted that the present application does not limit the specific structure of the control unit, and it can be reasonably selected and set according to actual needs.

[0067] In this embodiment, see Figure 3 Combined with Figure 8 As shown, the cover moving device further includes: a limiting unit 5.

[0068] The limiting unit 5 is arranged on the movement path of the sliding member 32, and the control unit is suitable for starting the driving unit 1 to output the driving force when the sliding member 32 is not in contact with the limiting unit 5, and stopping the driving unit 1 from outputting the driving force when the sliding member 32 is in contact with the limiting unit 5.

[0069] In this embodiment, two limiting units 5 are included, one limiting unit 5 is provided at the first end of the transmission rod 31, and the other limiting unit 5 is provided at the second end of the transmission rod 31. The first end of the transmission rod 31 is the end close to the reversing member 21, and the second end of the transmission rod 31 is the end away from the reversing member 21.

[0070] When the drive unit 1 outputs the driving force for forward rotation, the slider 32 drives the speed-multiplying mechanism 4 to move in the second direction, and at the same time, the cover 6 slowly opens. As the slider 32 moves, when the slider 32 contacts the limit unit 5 provided at the second end of the transmission rod 31, the control unit stops the drive unit 1 from outputting the driving force, completing the task of opening the cover 6.

[0071] Conversely, when the drive unit 1 outputs a reverse driving force, the slider 32 drives the speed mechanism 4 to move in a direction opposite to the second direction, while the cover 6 slowly closes. As the slider 32 moves, when the slider 32 contacts the limit unit 5 provided on the first end of the transmission rod 31, the control unit stops the drive unit 1 from outputting the driving force, completing the closing task of the cover 6.

[0072] It should be noted that the present application does not limit the specific structure and position of the limit unit 5, and can be reasonably selected and set according to actual needs. The two limit units 5 can be respectively arranged on the sides of the two groups of transmission units 3, or the two limit units 5 can be concentrated at the first end and the second end of a group of transmission units 3.

[0073] By setting the limiting unit 5, the top cover 6 can be opened or closed accurately, which not only improves the safety of the cover moving device during use, but also reduces damage to the cover moving device and extends the service life of the cover moving device.

[0074] In addition, see Figure 2 Combined with Figure 3 As shown, the cover moving device further includes a coupling 8 .

[0075] Couplings 8 are provided between the drive unit 1 and the connecting rod 13 , between the connecting rod 13 and the reversing member 21 , and between the reversing member 21 and the transmission unit 3 . The couplings 8 can transmit power well, making the power transmission of the cover moving device more stable.

[0076] The present application also discloses a loading device, comprising a loading body and the above-mentioned cover moving device, wherein the cover moving device is connected to the loading body.

[0077] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.

[0078] When the cover needs to be opened, the control unit activates motor 11 to generate forward power. After being decelerated by reduction gears 12 on both sides, the motor outputs a driving force at the same speed but in opposite directions, which is then transmitted to connecting rod 13. Connecting rod 13 drives reversing member 21, which in turn switches the direction of rotation and drives transmission unit 3. Transmission unit 3 converts rotational motion into linear motion, driving speed unit 4 and cover 6 in a second direction. When slider 32 contacts stop member 5 at the second end of transmission rod 31, the control unit stops motor 11, completing the task of opening cover 6.

[0079] When the cover needs to be closed, the control unit activates motor 11 to generate reverse power. After being decelerated by reduction gears 12 on both sides, the output power is transmitted to connecting rod 13 at the same speed and in the opposite direction. Connecting rod 13 drives reversing member 21, which in turn switches the direction of rotation and drives transmission unit 3. Transmission unit 3 converts rotational motion into linear motion, driving speed unit 4 and cover 6 in opposite directions. When slider 32 contacts stopper 5 at the first end of transmission rod 31, the control unit stops motor 11, completing the closing of cover 6.

[0080] When there is no power supply, manually or mechanically rotating the third connection end 212 of the reversing member 21 can drive the motor 11 and the transmission unit 3 to move, thereby driving the cover 6 to move. By rotating the reversing member 21 forward or backward, the cover 6 can be opened or closed.
