Description

Technical Field

[0001] This invention relates to the technical field of baby products, and in particular to a baby care device. Background Technology

[0002] Baby care equipment is used to care for infants and toddlers, freeing up the caregiver's hands and relieving their stress. Common baby care equipment includes baby seats, cribs, and baby rockers. Baby care equipment encourages the baby to move up and down and / or side to side relative to the ground, thus providing pleasure and comfort.

[0003] The existing patent with publication number CN104055355B discloses a variable motion baby seat. It uses a second motor to rotate in one direction to drive the seat to move up and down back and forth, and a first motor to rotate in one direction to drive the seat to move back and forth horizontally. By moving up and down back and forth / horizontally back and forth, it can move alone or simultaneously in two dimensions to reproduce a large number of motion trajectories in two dimensions to better mimic the movements of infant caregivers and reduce the stress on infant caregivers.

[0004] The existing technical solutions mentioned above have the following drawbacks: the double scissor mechanism is connected to the support platform and the rigid platform respectively. When the seat moves up and down back and forth, the double scissor mechanism not only rolls and rubs against the rigid platform, but also slides and rubs against the rigid platform and the support platform respectively. These frictions are prone to generating noise, which is not conducive to taking care of infants and young children. Summary of the Invention

[0046] The sliding groove is in a strip shape and is perpendicular to the track.

[0047] In summary, the present application has the following beneficial technical effects:

[0048] Compared with the prior art, the present application provides a baby care device, which comprises a horizontal reciprocating mechanism and a vertical reciprocating mechanism, so that the support device can reciprocate back and forth in at least two dimensions. When the support device supports the baby, it can effectively simulate the movement of the baby caregiver when caring for the baby. On the one hand, it plays a role in pacifying and pleasing the baby, and on the other hand, it relieves the pressure of the baby caregiver, and is worth promoting. When the vertical reciprocating mechanism drives the support device to reciprocate vertically, the mounting cover limits the rotation of the lifting piece, so that friction is generated between the mounting cover and the lifting piece. However, the noise generated by the friction is small, so as to reduce the impact of noise on the baby and improve the experience of caring for the baby.

[0049] The lifting cylinder is sleeved with the driving sleeve to facilitate the driving sleeve to drive the lifting cylinder to move vertically and reciprocate back and forth. The driving sleeve is provided with a driving groove, which can be a threaded groove or a ring groove with a slope. When the driving groove is a threaded groove, the driving sleeve is driven to rotate back and forth in two directions to drive the lifting cylinder to move vertically and reciprocate back and forth. When the driving groove is a ring groove with a slope, the driving sleeve can drive the lifting cylinder to move vertically and reciprocate back and forth by rotating in one direction. When the driving groove is a ring groove, in order to improve the balance and stability of the lifting cylinder during lifting and reduce noise, the driving groove is provided with at least two driving grooves, and the lifting cylinder is correspondingly provided with at least two sliding members. The adjacent two sliding members of the at least two sliding members are located on both sides of the lifting cylinder, and the at least two sliding members are correspondingly clamped in the at least two driving grooves. In order to reduce the friction between the driving groove and the sliding member, the sliding member can be selected as a roller or a bearing to further reduce noise.

[0050] The first rolling element is arranged between the lifting cylinder and the fixed shaft, and is a linear bearing. On one hand, the sliding friction between the lifting cylinder and the fixed shaft is changed into rolling friction, so as to reduce noise. On the other hand, the axis of the lifting cylinder and the axis of the fixed shaft are located on the same straight line, so as to further reduce the noise between the lifting cylinder and the fixed shaft. The second rolling element is arranged between the connecting element of the driving sleeve and the mounting cover, and is a bearing. The sliding friction between the connecting element of the driving sleeve and the mounting cover is changed into rolling friction, so as to reduce friction and noise. The third rolling element is arranged between the connecting sleeve of the driving sleeve and the fixed seat, and is a bearing. The sliding friction between the connecting sleeve of the driving sleeve and the fixed seat is changed into rolling friction, so as to reduce friction and noise. Because the axis of the second rolling element and the axis of the third rolling element are located on the same straight line, and because the axis of the second rolling element and the axis of the first rolling element are located on the same straight line, the axis of the lifting cylinder, the axis of the driving sleeve and the axis of the fixed shaft are located on the same straight line. On one hand, the stability and balance of the driving sleeve when driving the lifting cylinder to do vertical reciprocating motion are improved, so as to reduce noise. On the other hand, the energy consumption of the driving sleeve when driving the lifting cylinder to do vertical reciprocating motion is effectively reduced, so as to save energy.

[0051] The lifting rod passes through the through hole and extends out of the mounting cover. The through hole is located outside the connecting groove, so that the mounting cover plays a role in limiting the rotation of the lifting cylinder through the through hole and the lifting rod. The limiting assembly is arranged between the mounting cover and the lifting cover. On one hand, the limiting assembly limits the rotation of the lifting cover relative to the mounting cover, so as to limit the rotation of the lifting cylinder, so that the lifting cylinder and the lifting cover can only do vertical reciprocating motion. On the other hand, the limiting assembly changes the sliding friction between the lifting cover and the mounting cover into rolling friction, so as to reduce noise. Because the limiting assembly includes at least three groups of first sliding elements and at least three groups of second sliding elements, the at least three groups of first sliding elements and the at least three groups of second sliding elements are located between the lifting cover and the mounting cover, and are arranged at intervals. The second sliding element is located above the first sliding element, so as to improve the stability and balance of the lifting cover and the lifting element relative to the mounting cover when doing vertical reciprocating motion, so as to improve the experience of taking care of infants. Because there is a gap between the hole wall of the through hole and the lifting rod, the friction between the through hole and the lifting rod is reduced, which is conducive to reducing noise.

[0052] The elastic member is arranged between the fixing seat and the lifting cylinder. When the lifting cylinder is lifted upward, the elastic member pushes the lifting cylinder upward to reduce the speed. When the lifting cylinder is lowered, the elastic member buffers the speed of the lifting cylinder, improves the balance and stability, and makes the driving groove in the top of the slot wall abut against the sliding member to drive the lifting cylinder to move downward. Without the elastic member, the speed of the lifting cylinder is too fast, the balance and stability are poor, and the sliding member in the vertical reciprocating motion abuts against the bottom of the slot wall of the driving groove, which is not novel. When the driving sleeve does not drive the lifting cylinder to rotate, the sliding member can exist a gap between the top and bottom of the slot wall of the driving groove due to the effect of the elastic member.

[0053] Further, when the driving motor suddenly stops, the worm tends to rotate the turbine due to inertia, the lifting cylinder tends to move downward due to gravity, and the lifting cylinder tends to drive the driving sleeve to rotate. The elastic member limits the downward movement of the lifting cylinder, and the turbine and the worm are automatically locked to limit the rotation of the driving sleeve, which improves the stability and balance, reduces the shock of the baby due to the sudden stop of the driving motor, and improves the use experience.

[0054] The mounting cover clamps the track through two rollers, which improves the balance and stability of the horizontal reciprocating motion of the mounting cover, reduces the noise, limits the disengagement between the roller and the track, maintains the contact between the roller and the track, improves the balance and stability of the horizontal reciprocating motion of the mounting cover, reduces the noise, and reduces the friction between the roller and the track. The driving disc drives the sliding block to slide in the sliding groove to drive the mounting cover to move on the track, controls the movement speed of the mounting cover by controlling the rotation speed of the driving disc, and controls the horizontal motion of the mounting cover.

[0055] The safety cover is arranged on the lifting cover and has a gap with the lifting cover to reduce the friction between the lifting cover and the safety cover, thereby reducing the noise. When the lifting cover is lifted to the highest position, the bottom of the lifting cover is below the top of the safety cover to limit the lifting cover from being pinched when moving up and down, and improve the safety coefficient.

Accordingly, they can be changed according to different positions, different use states, etc. Therefore, these or other orientation terms should not be interpreted as limiting terms.

[0067] The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of implementations consistent with some aspects of the present disclosure.

[0068] The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. As used in the present disclosure, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0069] The present disclosure is further described in greater detail by way of reference only to the following examples.

[0070] Reference Figures 1 to 7This invention discloses an infant care device, comprising a horizontal reciprocating motion mechanism 1, a vertical reciprocating motion mechanism 2, a support device 3, and a mounting base 9. The horizontal reciprocating motion mechanism 1 is mounted on the mounting base 9, the vertical reciprocating motion mechanism 2 is mounted on the horizontal reciprocating motion mechanism 1, and the support device 3 is mounted on the vertical reciprocating motion mechanism 2. This device can drive the support device 3 to reciprocate horizontally or vertically independently, or simultaneously, thereby enhancing the infant care experience. The horizontal reciprocating motion mechanism 1 includes a mounting cover 11, and the vertical reciprocating motion mechanism 2 is mounted on the mounting cover 11. The vertical reciprocating motion mechanism 2 includes a lifting member 21 and a drive mechanism 22 for moving the lifting member 21. The lifting member 21 is located inside the mounting cover 11 and extends through the mounting cover 11 to the outside of the mounting cover 11, which restricts the rotation of the lifting member 21. The support device 3 is located outside the mounting cover 11 and mounted on the lifting member 21. Compared with existing technologies, by setting up a horizontal reciprocating motion mechanism 1 and a vertical reciprocating motion mechanism 2, the support device 3 can reciprocate in at least two dimensions. When the support device 3 supports an infant, it can effectively mimic the movements of a caregiver when caring for an infant. On the one hand, it soothes and pleases the infant; on the other hand, it reduces the stress on the caregiver, making it worthy of promotion. When the vertical reciprocating motion mechanism 2 drives the support device 3 to perform vertical reciprocating motion, friction is generated between the mounting cover 11 and the lifting component 21 because the mounting cover 11 restricts the rotation of the lifting component 21. However, the noise generated by this friction is relatively small, thus reducing the impact of noise on the infant and improving the caregiving experience.

[0071] In some embodiments, the lifting member 21 includes a lifting cylinder 211 and a lifting rod 212 disposed at the end of the lifting cylinder 211, such as Figure 2 As shown, the lifting rod 212 is located at the top of the lifting cylinder 211; the driving mechanism 22 includes a driving sleeve 221, a driving rod for driving the driving sleeve 221 to rotate, and a driving motor 223 for driving the driving rod to rotate. The driving sleeve 221 is connected to the lifting cylinder 211. The drive sleeve 221 can be fitted onto the lifting cylinder 211, or the lifting cylinder 211 can be fitted onto the drive sleeve 221. Those skilled in the art can configure it as needed. If the lifting cylinder 211 is fitted onto the drive sleeve 221, the length of the drive sleeve 221 will become longer (the length of the drive sleeve 221 is relative to the length when the drive sleeve 221 is fitted onto the lifting cylinder 211) because the drive sleeve 221 is connected to the drive rod. This will result in the baby care device being taller, requiring more space and making it difficult to package and transport. Therefore, this application describes the invention with the drive sleeve 221 fitted onto the lifting cylinder 211, and the lifting cylinder 211 fitted onto the drive sleeve 221 should also be the inventive point and scope of protection of this application.

[0072] Further, the driving sleeve 221 is provided with a driving groove 2211, and the lifting cylinder 211 is provided with a sliding piece 2111; wherein, the sliding piece 2111 can also be arranged on the driving sleeve 221, and the driving groove 2211 can also be arranged on the lifting cylinder 211, that is, how to arrange the driving groove 2211 and the sliding piece 2111 can be arranged by the person skilled in the art according to the needs. In terms of the present application, since the driving sleeve 221 is sleeved on the lifting cylinder 211, the driving groove 2211 is arranged on the inner wall of the driving sleeve 221, the sliding piece 2111 is arranged on the outer wall of the lifting cylinder 211, the sliding piece 2111 is movably clamped in the driving groove 2211, and the driving sleeve 221 drives the lifting cylinder 211 to rotate through the driving groove 2211 and the sliding piece 2111. Since the lifting cylinder 211 is limited to rotate by the mounting cover 11, the lifting cylinder 211 moves back and forth in the vertical direction. The driving groove 2211 can be a threaded groove arranged on the circumferential inner wall of the driving sleeve 221. When the driving groove 2211 is a threaded groove, the driving sleeve 221 rotates in a first direction to drive the lifting cylinder 211 to move vertically upward, and the driving sleeve 221 rotates in a second direction to drive the lifting cylinder 211 to move vertically downward. The driving groove 2211 can also be an annular groove with a slope, that is, the driving groove 2211 is arranged obliquely in the driving sleeve 221, and the annular groove is arranged on the circumferential inner wall of the driving sleeve 221. When the driving groove 2211 is an annular groove, in order to improve the balance and stability of the lifting cylinder 211 moving back and forth in the vertical direction and to reduce noise, the driving groove 2211 is provided with at least two, and the sliding piece 2111 is provided with at least two corresponding to the at least two driving grooves 2211. The at least two sliding pieces 2111 are correspondingly clamped in the at least two driving grooves 2211; when the driving sleeve 221 rotates, the driving sleeve 221 drives the at least two sliding pieces 2111 to move through the at least two driving grooves 2211; the lowest point of one of the adjacent two driving grooves 2211 in the at least two driving grooves 2211 is located above the highest point of the other driving groove 2211, and the highest point of one of the adjacent two driving grooves 2211 in the at least two driving grooves 2211 is located above the lowest point of the other driving groove 2211, so that the at least two sliding pieces 2111 are arranged on both sides of the lifting cylinder 211; wherein, as shown in the drawings, the adjacent two sliding pieces 2111 in the at least two sliding pieces 2111 are located on both sides of the lifting cylinder 211, and one of the adjacent sliding pieces 2111 in the at least two sliding pieces 2111 is located above the other sliding piece 2111. In order to reduce the cost, as shown in the drawings, the driving groove 2211 can be provided with two, and the corresponding sliding piece 2111 is also provided with two, and the two sliding pieces 2111 are clamped in the two driving grooves 2211, respectively. In order to reduce friction, the sliding piece 2111 can be a bearing wheel or other suitable wheel. Figure 2 Figure 2 ​​

[0073] In some embodiments, the mounting cover 11 is provided with a fixed shaft 111 and a fixed seat 112. The fixed seat 112 is fixedly connected with the bottom of the mounting cover 11. The fixed seat 112 is located below the fixed shaft 111.

The lifting cylinder 211 is sleeved on the fixed shaft 111. At least one first rolling element 4 is arranged between the lifting cylinder 211 and the fixed shaft 111. The first rolling element 4 changes the sliding friction between the lifting cylinder 211 and the fixed shaft 111 into rolling friction. On the one hand, it plays a role in reducing noise. On the other hand, it plays a role in reducing the energy consumption required to drive the movement of the lifting cylinder 211. The first rolling element 4 is provided with two. There is a gap between the two first rolling elements 4. The axes of the two first rolling elements 4 and the fixed shaft 111 are located on the same straight line. This is conducive to optimizing the stability and balance of the movement of the lifting cylinder 211 relative to the fixed shaft 111, so as to reduce noise. The first rolling element 4 can be selected as a linear bearing. Of course, the first rolling element can also be selected as other suitable rolling elements.

The driving sleeve 221 is located in the mounting cover 11, and the outer wall and the top of the driving sleeve 221 are both spaced from the inner cavity of the mounting cover 11, so as to limit the friction between the outer wall and the top of the driving sleeve 221 and the inner cavity of the mounting cover 11, thereby reducing noise and energy consumption (reducing the energy consumption of driving the driving sleeve 221 to rotate). The second rolling element 5 is arranged between the driving sleeve 221 and the connecting piece 113, the second rolling element 5 can be a bearing, and the second rolling element 5 can also be other suitable rolling elements, and the fixing shaft 111 is located in the second rolling element 5; the second rolling element 5 changes the sliding friction between the driving sleeve 221 and the connecting piece 113 into rolling friction, so as to reduce the friction between the driving sleeve 221 and the connecting piece 113, thereby reducing noise and energy consumption. The fixing seat 112 is provided with a connecting sleeve 1121, the driving sleeve 221 is sleeved with the connecting sleeve 1121, so as to facilitate the rotation of the driving sleeve 221 relative to the connecting sleeve 1121; the fixing seat 112 is provided with a connecting block, the connecting block is located in the connecting groove, the connecting block is provided with a plug-in groove, the center of the plug-in groove is located on the same straight line as the axis of the connecting sleeve 1121; the fixing shaft 111 is inserted into the plug-in groove and fixedly connected with the plug-in groove, so as to realize the fixed connection between the fixing shaft 111 and the fixing seat 112. The third rolling element 6 is arranged between the driving sleeve 221 and the connecting sleeve 1121, the third rolling element 6 is a bearing, of course, the third rolling element 6 can also be other suitable rolling elements, the third rolling element 6 changes the sliding friction between the driving sleeve 221 and the connecting sleeve 1121 into rolling friction, on the one hand, the rotation of the driving sleeve 221 relative to the connecting sleeve 1121 is more balanced and stable, so as to reduce noise, on the other hand, the force required by the driving sleeve 221 to overcome the friction between the driving sleeve 221 and the connecting sleeve 1121 is reduced, so as to reduce energy consumption.

[0075] Further, the axis of the first rolling element 4 and the axis of the second rolling element 5 are located on the same straight line, and the axis of the second rolling element 5 and the axis of the third rolling element 6 are located on the same straight line, so that the axis of the first rolling element 4, the axis of the second rolling element 5 and the axis of the third rolling element 6 are located on the same straight line, thereby the axes of the fixing shaft 111, the first rolling element 4, the lifting cylinder 211 and the driving sleeve 221 are located on the same straight line, so as to optimize the stability and balance of the driving sleeve 221 when driving the lifting cylinder 211 to move, thereby reducing noise, in addition, the force required by the driving sleeve 221 to drive the lifting cylinder 211 to move can also be reduced, so as to reduce energy consumption.

[0076] In some embodiments, the driving sleeve 221 comprises a sleeve 2212 and a turbine 2213 fixed at the bottom of the sleeve 2212, and a driving groove 2211 is arranged in the sleeve 2212, and the turbine 2213 is sleeved with the connecting sleeve 1121 through the third rolling part 6. The driving rod is a worm 222, which is installed on the fixed seat 112 and engaged with the turbine 2213. In order to reduce the vibration between the worm 222 and the fixed seat 112, a damping sleeve is arranged between the two ends of the worm 222 and the fixed seat 112. The damping sleeve absorbs the vibration generated by the rotation of the worm 222, thereby reducing the noise. In addition, since the damping sleeve is elastic, the damping sleeve also adjusts the engagement state between the worm 222 and the turbine 2213, so that the connection state between the worm 222 and the turbine 2213 is optimal, thereby facilitating the rotation of the worm 222 and the turbine 2213. The driving motor 223 is fixedly connected with the inner cavity of the mounting cover 11. In order to reduce the vibration between the driving motor 223 and the mounting cover 11, a damping pad is arranged between the driving motor 223 and the inner cavity of the mounting cover 11. The damping pad absorbs the vibration generated by the driving motor 223 during operation. The driving motor 223 is connected with the worm 222 through a transmission part to drive the rotation of the worm 222. The transmission part can be two meshing gears, and the two gears are respectively connected with the driving motor 223 and the worm 222. The transmission part can also comprise two belt pulleys and a belt connected between the two belt pulleys, and the two belt pulleys are respectively connected with the worm 222 and the motor. The transmission part can also be two sprockets and a chain connected between the two sprockets, and the two sprockets are respectively connected with the worm 222 and the motor.

[0077] In some embodiments, the elastic part 7 is arranged between the fixed shaft 111 and the lifting cylinder 211. The elastic part 7 can be a compression spring, and the elastic part 7 is located between the fixed shaft 111 and the connecting sleeve 1121 to limit the displacement of the elastic part 7. The end of the lifting cylinder 211 is provided with a groove for clamping the elastic part 7, and the elastic part 7 is clamped in the groove to limit the displacement of the elastic part 7. Figure 2As shown, the distance from the top to the bottom of the driving groove 2211 is greater than the vertical height of the sliding member 2111 (when the sliding member 2111 is a wheel, the distance from the top to the bottom of the driving groove 2211 is greater than the diameter of the sliding member 2111); when the driving sleeve 221 drives the lifting cylinder 211 to move upward through the driving groove 2211, the relatively bottom groove wall of the driving groove 2211 abuts against the sliding member 2111; when the driving sleeve 221 drives the lifting cylinder 211 to move downward through the driving groove 2211, the relatively top groove wall of the driving groove 2211 abuts against the sliding member 2111 due to the action of the elastic member 7. When the lifting cylinder 211 moves upward, the elastic member 7 plays a role in pushing the lifting cylinder 211 to move upward, so as to reduce the speed; when the lifting cylinder 211 moves downward, on the one hand, the elastic member 7 plays a role in buffering the speed of the lifting cylinder 211, which is conducive to improving the balance and stability, and on the other hand, the relatively top groove wall of the driving groove 2211 abuts against the sliding member 2111 due to the action of the elastic member 7, so as to realize the driving sleeve 221 driving the lifting cylinder 211 to move downward. If there is no elastic member 7, on the one hand, the speed of the lifting cylinder 211 moving downward is too fast, and the balance and stability are poor, and on the other hand, the sliding member 2111 abuts against the relatively bottom groove wall of the driving groove 2211 during the vertical reciprocating motion of the lifting cylinder 211, which is not novel. When the driving sleeve 221 does not drive the lifting cylinder 211 to rotate, the sliding member 2111 can exist a gap between the top and bottom groove walls of the driving groove 2211 due to the action of the elastic member 7.

[0078] In some embodiments, the connecting member 113 is provided with at least one through hole 1131, the through hole 1131 is located outside the connecting groove, the lifting rod 212 passes through the through hole 1131 and extends outside the mounting cover 11; the through hole 1131 plays a role in limiting the rotation of the lifting rod 212, so as to limit the rotation of the lifting cylinder 211 (in the present application, the through hole 1131 preferably does not limit the rotation of the lifting rod 212, so as to limit the friction between the hole wall of the through hole 1131 and the lifting rod 212).

[0079] Further, the vertical reciprocating mechanism 2 further comprises a lifting cover 23, which is covered on the mounting cover 11 and connected with the lifting piece 21, i.e. the lifting cover 23 is connected with the top of the lifting rod 212, when the lifting cylinder 211 moves up and down, the lifting rod 212 moves with the lifting cylinder 211, and the lifting rod 212 drives the lifting cover 23 to move up and down, so as to realize the vertical reciprocating motion of the lifting cover 23, and the supporting device 3 is installed on the lifting cover 23, so that the supporting device 3 moves vertically and reciprocally. It should be pointed out that the supporting device 3 is used to support the infant. There is a gap between the lifting cover 23 and the mounting cover 11, and a limiting assembly 8 is arranged between the lifting cover 23 and the mounting cover 11, which not only limits the rotation of the lifting cover 23 relative to the mounting cover 11, but also changes the sliding friction between the lifting cover 23 and the mounting cover 11 into rolling friction, so as to improve the stability and balance of the lifting cover 23 during lifting, and reduce the noise during lifting of the lifting cover 23. Because the limiting assembly 8 limits the rotation of the lifting cover 23 relative to the mounting cover 11, if there is a gap between the hole wall of the through hole 1131 and the lifting rod 212, the friction between the lifting rod 212 and the hole wall of the through hole 1131 can be limited, so as to reduce the energy consumption and noise.

[0080] In some embodiments, the limiting assembly 8 comprises at least three groups of first sliding pieces 81 arranged in the inner cavity of the lifting cover 23 and three groups of second sliding pieces 82 arranged on the outer peripheral wall of the mounting cover 11, the at least three groups of first sliding pieces 81 and the at least three groups of second sliding pieces 82 are arranged at intervals, the at least three groups of first sliding pieces 81 are arranged around the mounting cover 11 and abut against the outer wall of the mounting cover 11, and the at least three groups of second sliding pieces 82 abut against the inner wall of the lifting cover 23; it should be pointed out that the number of the first sliding pieces 81 and the second sliding pieces 82 can be arranged as required, when the cross section of the mounting cover 11 is circular, the first sliding pieces 81 and the second sliding pieces 82 can be arranged in three groups. Figure 6As shown, the cross section of the part where the mounting cover 11 is covered by the lifting cover 23 is octagonal, and the cross section of the lifting cover 23 is quadrangular. The outer wall of the mounting cover 11 is provided with at least three first limiting grooves 83 corresponding to at least three groups of first sliding members 81. The first limiting grooves 83 are in the shape of long strips and are arranged in parallel with the fixed shaft 111. The at least three groups of first sliding members 81 are movably clamped in the at least three first limiting grooves 83. On the one hand, the sliding friction between the lifting cover 23 and the mounting cover 11 is changed into rolling friction. On the other hand, the rotation of the lifting cover 23 relative to the mounting cover 11 is limited. The inner wall of the lifting cover 23 is provided with at least three second limiting grooves corresponding to at least three groups of second sliding members 82. The second limiting grooves are in the shape of long strips and are arranged in parallel with the fixed shaft 111. The at least three groups of second sliding members 82 are movably clamped in the at least three second limiting grooves. On the one hand, the sliding friction between the lifting cover 23 and the mounting cover 11 is changed into rolling friction. On the other hand, the rotation of the lifting cover 23 relative to the mounting cover 11 is limited. When the lifting cover 23 is at the lowest point, the at least three groups of second sliding members 82 are above the at least three groups of first sliding members 81. Therefore, the lifting cover 23 is supported between the first sliding members 81 and the second sliding members 82 when it moves up and down, which is beneficial to improve the balance and stability of the lifting cover 23 when it moves up and down, so as to reduce noise. The first sliding members 81 and the second sliding members 82 can be bearings, wheels or other suitable sliding members.

[0081] In some embodiments, in order to improve the safety factor of the device, a safety cover 10 is further arranged. The safety cover 10 covers the lifting cover 23 and has a gap with the lifting cover 23. The safety cover 10 is fixedly connected with the mounting cover 11. When the lifting cover 23 is raised to the highest position, the bottom of the lifting cover 23 is below the top of the safety cover 10. The safety cover 10 limits the user's hand or the like from reaching the gap between the lifting cover 23 and the mounting cover 11, which is between the bottom of the lifting cover 23 and the mounting cover 11, so as to effectively prevent being pinched.

[0082] In some embodiments, the mounting seat 9 includes a bottom plate 91 and support seats 92 arranged on both sides of the bottom plate 91. The horizontal reciprocating mechanism 1 includes at least two tracks 12, as shown in Figure 2 and Figure 3 As shown, the present application is provided with two tracks 12, which are arranged in parallel. The two tracks 12 are arranged between the two support seats 92 and have a gap therebetween. The tracks 12 are above the bottom plate 91 and have a gap with the bottom plate 91. The mounting cover 11 is movably connected with the tracks 12 and has a gap with the bottom plate 91, so as to limit the friction between the bottom plate 91 and the mounting cover 11.

[0083] Further, the mounting cover 11 is provided with at least two groups of rolling assemblies 13, the number of the rolling assemblies 13 can be set according to the requirement, at least two groups of the rolling assemblies 13 are arranged on two sides of the mounting cover 11, and the mounting cover 11 is movably connected with the track 12 through the rolling assemblies 13. In order to improve the balance and stability of the movement of the mounting cover 11 on the two tracks 12, four groups of the rolling assemblies 13 are arranged, two groups of the rolling assemblies 13 are arranged on one side of the mounting cover 11, and the other two groups of the rolling assemblies 13 are arranged on the other side of the mounting cover 11. The rolling assembly 13 comprises two corresponding arranged rollers 131, one roller 131 is located above the other roller 131, the track 12 is located between the two rollers 131 and respectively abuts against the two rollers 131, so that the two rollers 131 clamp the track 12, on the one hand, the function of limiting the mounting cover 11 from being taken off from the track 12 is achieved, and the rollers 131 are prevented from being taken off from the track 12 when the device is carried, so that the abutment between the rollers 131 and the track 12 is maintained, on the other hand, the back and forth reciprocating movement of the mounting cover 11 on the track 12 is more stable and balanced, so that the noise is reduced. The track 12 is provided with a rail groove 121 on two sides, the rail groove 121 is arranged along the length direction of the track 12, the roller 131 is clamped in the rail groove 121, and the rail groove 121 plays a role of limiting the roller 131 from being taken off from the track 12.

[0084] In some embodiments, the horizontal reciprocating mechanism 1 further comprises a power mechanism 14 connected with the mounting cover 11 and the bottom plate 91 respectively, and the power mechanism 14 is used to drive the mounting cover 11 to reciprocate along the length direction of the track 12. The power mechanism 14 comprises a driving disc 141, a slider 142 eccentrically arranged on the disc surface of the driving disc 141, a sliding groove 143 arranged on the bottom plate 91, and a power source 144. The power source 144 is installed in the mounting cover 11 and fixedly connected with the inner cavity of the mounting cover 11. The power source 144 is connected with the driving disc 141 and used to drive the driving disc 141 to rotate. The slider 142 is movably clamped in the sliding groove 143. In use, the power source 144 drives the driving disc 141 to rotate, and the driving disc 141 drives the slider 142 to reciprocate in the sliding groove 143. Since the sliding groove 143 is arranged on the bottom plate 91, the bottom plate 91 is fixed and immovable, thus the mounting cover 11 is driven to move, so as to realize the reciprocating movement of the mounting cover 11 along the length direction of the track 12. The power source 144 comprises a power motor 145 and a gear box 146, both of which are installed in the inner cavity of the mounting cover 11. The power motor 145 is connected with the gear box 146 through a transmission member, which can be the component mentioned above. The driving disc 141 is installed at the bottom of the gear box 146, and the power motor 145 drives the driving disc 141 to rotate through the gear box 146, so as to realize the reciprocating movement of the mounting cover 11 along the track 12.
