Abstract
Description
Technical Field
[0001] This utility model relates to the field of rocking drive control technology for beds and chairs, specifically to a buffered lateral movement device and a cradle bed. Background Technology
[0002] Traditional cradles typically use simple mechanical structures (such as rigid stops or direct drives) to switch the swing direction. When the swing reaches its limit, the drive mechanism experiences noticeable reversal shaking and jerking due to the sudden change in direction, affecting the baby's sleep quality. It may also cause wear and tear on the drive mechanism or connecting parts due to the instantaneous impact, reducing the product's lifespan. Some existing technologies attempt to mitigate the impact by adding damping elements, but such designs are often complex or costly and difficult to integrate effectively into the compact cradle structure. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a buffered lateral movement device and a cradle bed, which can make the cradle bed make buffered lateral movements, prevent wear on the drive mechanism or connecting parts caused by instantaneous impact force, reduce the service life of the product, and improve the sleep quality of infants.
[0004] To achieve the above objectives, this utility model employs the following technical solution:
[0005] On the one hand, this utility model provides a buffered lateral movement device, including: at least two support rods, a connecting plate, a bracket, a collar, a drive device, and a crank;
[0006] The support rods are parallel to each other, the connecting plate is provided with a first sleeve that is parallel to each other, the bracket is provided with a second sleeve that is parallel to each other, the support rod is perpendicular to the connecting plate and the bracket, inserted into the first sleeve and the second sleeve, slidably connected to the first sleeve, and fixedly connected to the second sleeve;
[0007] The drive unit is installed in the middle of the bracket, and the collar is connected to the side of the connecting plate near the bracket. The input shaft of the crank is connected to the output shaft of the drive unit. The output shaft of the crank is installed in the groove of the collar and can slide along the groove. The groove of the collar includes a first boundary section, a transition section and a second boundary section. The transition section is an arc on a circle centered on the output shaft of the drive unit. When the output shaft of the crank slides along the transition section, the relative position of the connecting plate and the bracket remains unchanged.
[0008] Furthermore, the drive device includes a motor assembly and a gearbox, both of which are mounted in the middle of the bracket. The gearbox is mounted on one side of the motor assembly, with its input end connected to the output end of the motor assembly and its output end connected to the input shaft of the crank.
[0009] The input end of the gearbox is connected to the output end of the motor assembly via a belt drive.
[0010] Furthermore, the slot is an S-shaped slot.
[0011] Furthermore, it also includes a sliding sleeve, which is fitted between the support rod and the first sleeve to reduce friction.
[0012] On the other hand, this utility model provides a cradle bed, including the aforementioned buffered lateral movement device.
[0013] Furthermore, it also includes a bed board that is detachably connected to the connecting plate.
[0014] Furthermore, it also includes fixing blocks, installed on both sides of the support rod, for mounting the bed frame.
[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:
[0016] The buffered lateral motion device provided by this utility model consists of at least two support rods and a connecting plate forming a sliding structure. It also includes a collar, a drive device, and a crank to drive the connecting plate to slide. The groove of the collar includes a first boundary section, a transition section, and a second boundary section. The transition section is an arc segment on a circle centered on the output shaft of the drive device. When the output shaft of the crank slides along the transition section, the relative position of the connecting plate and the support remains unchanged. This allows the working parts connected to the connecting plate to make buffered lateral movements, preventing wear on the drive mechanism or connecting parts caused by instantaneous impact forces and reducing the service life of the product.
[0017] The cradle provided by this utility model includes a buffered lateral movement device, which can add buffer time while realizing the switching of the swing direction, prevent sudden changes in the movement direction, and improve the sleep quality of infants. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention. Example 1
[0025] This embodiment provides a buffered lateral movement device, such as... Figure 1 and Figure 2 As shown, it includes two support rods 1, two connecting plates 2, bracket 3, collar 4, drive device 5, and crank 6;
[0026] The two support rods 1 are parallel to each other. The two connecting plates 2 are provided with parallel first sleeves at both ends. The bracket 3 is provided with parallel second sleeves at both ends. The support rod 1 is perpendicular to the connecting plate 2 and the bracket 3, inserted into the first sleeve and the second sleeve, slidably connected to the first sleeve and fixedly connected to the second sleeve. The bracket 3 is located between the two connecting plates 2. A sliding sleeve 11 is also provided between the support rod 1 and the first sleeve to reduce the friction between the support rod 1 and the first sleeve.
[0027] The drive device 5 includes a motor assembly 8 and a gearbox 9. Both the motor assembly 8 and the gearbox 9 are installed in the middle of the bracket 3. The gearbox 9 is installed on one side of the motor assembly 8. The input end of the gearbox 9 is connected to the output end of the motor assembly 8 via a belt 10. The output end of the gearbox 9 is connected to the input shaft of the crank 6.
[0028] The collar 4 is connected to one of the connecting plates 2 near the bracket 3. The input shaft of the crank 6 is connected to the output shaft of the drive device 5. The output shaft of the crank 6 is installed in the slot 7 of the collar 4 and can slide along the slot 7. Figure 5As shown, the groove 7 of the collar 4 is S-shaped, including a first boundary section, a transition section and a second boundary section. The first boundary section is the end point away from the drive device 5. The transition section is an arc on a circle centered on the output shaft of the drive device 5. When the output shaft of the crank 6 slides along the transition section, the relative position of the connecting plate 2 and the bracket 3 remains unchanged.
[0029] When the buffered lateral movement device is in operation, the two connecting plates 2 are connected to the same rigid working part, such as... Figure 3 As shown:
[0030] Initially, the output shaft of the crank 6 is located at the starting point of the first boundary section. The motor assembly 8 is working and, through the transmission action of the gearbox 9, drives the input shaft of the crank 6 to rotate, causing the output shaft of the crank 6 to slide along the slot 7.
[0031] like Figure 4 As shown, when the output shaft of crank 6 slides to the transition section, the relative positions of the connecting plate 2 and the bracket 3 remain unchanged;
[0032] When the output shaft of crank 6 slides to the end point of the second boundary section and the motor assembly 8 continues to work, crank 6 first applies a pulling force close to the motor assembly 8 to the collar 4, and then applies a pushing force away from the motor assembly 8, pulling the connecting plate 2 to slide along the support rod 1, while driving the rigid working part to move, and also driving another connecting plate 2 to slide along the support rod 1.
[0033] When the relative sliding between the connecting plate 2 and the support rod 1 reaches the critical point, the output shaft of the crank 6 slides in the opposite direction along the second boundary section and enters the transition section. At this time, the relative position of the connecting plate 2 and the bracket 3 remains unchanged.
[0034] As the output shaft of crank 6 continues to slide, it slides in the opposite direction from the transition section to the starting point of the first boundary section. While the motor assembly 8 continues to work, crank 6 applies force to collar 4 again, causing connecting plate 2 to slide in the opposite direction along support rod 1 to the initial position.
[0035] Repeating the above actions can make the rigid workpiece make a cushioned lateral movement. Example 2
[0036] This embodiment provides a cradle bed, including a buffered lateral movement device as described in Embodiment 1. In this embodiment, the rigid working component is a bed board 12, which is detachably connected to a connecting plate 2. In this embodiment, the cradle bed also includes fixing blocks 13, which are installed on both sides of the support rod 1 for mounting the bed frame.
