Description

Technical Field

[0001] The present invention relates to the technical field of wardrobes, and more particularly to a lifting transmission structure and a lifting transmission control method. Background Art

[0002] Currently, wardrobes all have fixed hangers. Over time, movable, liftable hangers have gradually emerged. However, existing hangers all use a sliding rail to lift them up and down or a horizontal translation method. For example, the up and down lifting method requires the entire process of moving up and down to complete the process inside the wardrobe. As a result, although the hangers can be lifted up and down, they are still limited by the internal height of the wardrobe. At the same time, the movement of the sliding rail still occupies space inside the wardrobe, resulting in no change in the storage capacity inside the wardrobe. How to combine up and down movement with horizontal movement to achieve the lifting of hangers, thereby increasing the storage capacity of the wardrobe, is the technical problem to be solved by the present invention. Therefore, it is necessary to propose a lifting transmission structure and lifting transmission control method to at least partially solve the problems existing in the existing technology.

DETAILED DESCRIPTION

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0048] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0049] like Figures 1-16 As shown, the present invention provides a lifting transmission structure, including: a rotating rod 1, a first gear 3 arranged in a shell 2, a first rack 4 meshing with the first gear 3, and a first elastic member 5 connected to the first rack 4; the rotating rod 1 is arranged outside the shell 2 and is connected to the first gear 3, and the first elastic member 5 is connected to the shell 2 through a fixing member 6.

[0050] The working principle and beneficial effects of the above technical solution: The present invention provides a lifting transmission structure for the interior of a wardrobe, wherein two lifting transmission structures are symmetrically arranged inside the wardrobe (or only one can be arranged, and the other can be replaced by a rotatable structure such as a hinge shaft), and the rotating rods 1 of the two lifting transmission structures are connected by a cross bar 22 to form a clothes hanger. When in use, the user can use this lifting transmission structure to lift the clothes hanger. When the clothes hanger is lifted or lowered, the rotation of the rotating rod 1 will drive the first gear 3 to rotate. As the first gear 3 rotates, the first rack 4 engaged with it also translates. The first rack 4 can be connected to a sliding mechanism (or any structure that can guide its translation) arranged in the shell 2 to ensure that it can translate. As the first rack 4 slides, the first elastic member 5 is stretched. When the user has hung the clothes, the clothes hanger can be lifted upward. Under the action of the elastic force of the first elastic member 5, the first rack 4 can reset the rotating rod 1 through the first gear 3, thereby resetting the clothes hanger. Figure 1 shown.

[0051] Through the design of the above structure, the height of the wardrobe can be unrestricted, thereby increasing the storage capacity inside the wardrobe, and the clothes hanger provided with a lifting transmission structure can facilitate users to store and retrieve clothes. At the same time, lighting equipment can be pre-installed in the wardrobe and connected to the lifting transmission structure, and the lighting equipment can be turned on and off by lifting and lowering the lifting transmission mechanism. In addition, the lighting equipment can also be set to be controlled by various control methods such as manual control, electric control, and voice control. In addition to being set in the wardrobe, the lighting equipment can also be set on the rotating rod 1, thereby saving space and allowing the lighting range to move with the clothes on the lifting transmission structure, thereby allowing the lighting equipment to illuminate clothes without a large lumen, avoiding disturbing other people's sleep at night. The lighting equipment can use a non-breakpoint LED light strip, which can ensure uniform light emission while ensuring low voltage and increasing safety.

[0052] In one embodiment, a second gear 7, a second rack 8, and a second elastic member 9 are further provided in the housing 2. The second gear 7 is meshed with the first gear 3, the second rack 8 is meshed with the second gear 7, and the second rack 8 is connected to the housing 2 via the second elastic member 9. A third gear 10, a gas pressure support 11, and a rebounder 12 are also provided in the housing 2. The third gear 10 is meshed with the first gear 3, one end of the gas pressure support 11 is connected to the third gear 10, and the other end is connected to the housing 2. The rebounder 12 is provided on the housing 2, and the pop-up end of the rebounder 12 abuts against a stopper 13 on the third gear 10. The first rack 4 is provided with a toothed locator 14, which meshes with the first gear 3 through the teeth. A fixed slide 15 is provided in the housing 2, and the fixed slide 15 is provided with a positioning slide and a rack slide. The first rack 4 is slidably connected to the fixed slide 15 through the rack slide. The locator 14 is slidably connected to the fixed slide 15 through the positioning slide. A positioning slide 16 is provided on one side of the positioning slide of the locator 14, and a positioning pin 17 is provided in the positioning slide. The positioning pin 17 is located in the positioning slide 16. The fixing member 6 is provided on the housing 2, and the fixing member 6 is provided with a limiting column that passes through the first elastic member 5. A connecting rod 18 is provided in the housing 2, and one end of the connecting rod 18 is connected to one end of the first elastic member 5, and the other end is axially connected to a built-in pull rod 19 provided on the side wall of the housing 2. The other end of the first elastic member 5 is connected to a fixing rod provided on the first rack 4. A transmission shaft 20 is provided on the first gear 3. The transmission shaft 20 passes through the housing 2 and is connected to the rotating rod 1. A support plate 21 is provided between the rotating rod 1 and the housing 2. The support plate 21 is sleeved on the transmission shaft 20. The top of the rotating rod 1 is movably connected to an external pull rod 23 via a cross bar 22.

[0053] The working principle and beneficial effects of the above technical solution: This embodiment provides the following seven implementation methods:

[0054] The first embodiment is to further increase the torque when the rotating rod 1 is reset and increase the amount of hanging clothes. In this embodiment, a second gear 7, a second rack 8 and a second elastic member 9 are added. When the rotating rod 1 rotates, the first gear 3 not only drives the first elastic member 5 to stretch, but also drives the second gear 7 to rotate, thereby causing the second rack 8 to translate. The second rack 8 can be connected to a sliding mechanism (or any structure that can guide its translation) provided in the shell 2 to ensure that it can translate. The second rack 8 drives the second elastic member 9 to stretch. When the rotating rod 1 is reset, the first elastic member 5 and the second elastic member 9 act at the same time, thereby providing a greater torque for the rotation of the first gear 3, so that the cross bar 22 can support more clothes.

[0055] The second embodiment is to further slow down the speed of the rotating rod 1 when it is reset, thereby reducing the inertia caused by the rapid recovery. In this embodiment, a third gear 10, a gas pressure support 11 and a rebounder 12 are added. When the rotating rod 1 rotates and the clothes hanger moves down, as the first gear 3 rotates, the rotation of the third gear 10 will compress the gas pressure support 11, thereby playing a deceleration effect on the clothes hanger, and preventing the lifting transmission structure from being damaged due to excessive weight of clothes and excessive downward movement speed. While the user is hanging clothes, the air pressure in the gas pressure support 11 reaches equilibrium, so that it can continue to provide a deceleration effect when resetting. At the same time, the pop-up end of the rebounder 12 continues to abut against the stopper 13 of the third gear 10. When the clothes hanger is reset, as the third gear 10 resets, the stopper 13 will squeeze the pop-up end of the rebounder 12 to achieve a deceleration effect. At the same time, the gas pressure support 11 is stretched to further enhance the deceleration effect.

[0056] In the third embodiment, a positioner 14 is provided on the first rack 4, and a positioning slide 16 is provided on the positioner, and one end of the positioning pin 17 is connected to the inner bottom surface axis of the positioning slide through a crank, such as Figure 6 、 7 As shown, the other end is located in the positioning slide 16.

[0057] The positioning slide 16 can be divided into an entry and exit section, an entrance section, an entrance top section, a clamping section, an exit top section and an exit section; when the positioner 14 moves along with the first rack 4, the positioning pin 17 will sequentially pass through the entry and exit section (entry), the entrance section, the entrance top section, the clamping section, the exit top section, the exit section and the entry and exit section (exit). Figure 6 shown.

[0058] By setting the positioner 14, when pulling down the clothes hanger, when the rotating rod 1 rotates to the specified position (when the positioning pin 17 is located at the top section of the entrance), you can let go. Under the action of the first elastic member 5, the positioner 14 will reset and the positioning pin 17 will be engaged in the engaging section, thereby avoiding the automatic reset of the lifting transmission structure. When reset is required, you only need to rotate the rotating rod 1 again to make the positioning pin 17 enter the top section of the exit. After that, under the action of the first elastic member 5, the positioning pin 17 will enter the entrance and exit section through the exit section, thereby achieving reset.

[0059] In the fourth embodiment, in order to make the rotational torque of the hanger adjustable, a connecting rod 18 and a built-in pull rod 19 are added to the shell 2. When the torque needs to be adjusted, the end of the first elastic member 5 can be connected to or separated from the connecting rod 18 through the built-in pull rod 19 to adjust the torque.

[0060] In the fifth embodiment, in order to increase the height of the wardrobe and thus expand the capacity, an external pull rod 23 can be additionally provided on the horizontal bar 22 to facilitate the user to pull the hanger. When pulling down and resetting, it is convenient to operate only through the external pull rod 23. Figure 1 shown.

[0061] The sixth embodiment, based on the fifth embodiment, maintains the connection between the connecting rod 18 and the first elastic member 5. In this way, when resetting, it can be achieved by pushing the external pull rod 23 upward or by pushing the internal pull rod 19, thereby increasing the usage methods for users.

[0062] In a seventh embodiment, the above six embodiments are combined with each other to functionally integrate the lifting transmission structure according to needs.

[0063] In one embodiment, a pressure-bearing member 24 is further provided on the side wall of the shell 2, and the pressure-bearing member 24 consists of a horizontal plate 241 arranged horizontally, a vertical plate 242 arranged vertically on the shell 2 and a pressure-bearing plate 243 connecting the horizontal plate 241 and the vertical plate 242. The horizontal plate 241 is located above the vertical plate 242, and a gap is reserved between the end of the horizontal plate 241 and the shell 2. A rotating opening is provided on the horizontal plate 241, the vertical plate 242 abuts on the outer wall of the shell 2, and the vertical plate 242 is connected to the shell 2 through a rotating axis. An opening is provided on the pressure-bearing plate 243, and an inward-bent support rib is provided on the edge of the pressure-bearing plate 243. A tension rib 244 is provided between the vertical plate 242 and the pressure-bearing plate 243. The support sheet 21 abuts on the horizontal plate 241, and the rotating opening is adapted to the length of the support sheet 21.

[0064] The working principle and beneficial effects of the above technical solution: Because all the weight borne by the lifting transmission structure acts on the transmission shaft 20, when used for a long time, or when the user's wardrobe is too wide, the cross bar 22 is too long, and the clothes are too heavy, the transmission shaft 20 is at risk of bending or breaking. Therefore, in order to avoid the above risks and increase the service life of the lifting transmission structure, a pressure-bearing member 24 for auxiliary support is provided at the bottom of the support plate 21. When the rotating rod 1 is vertical, the bottom of the support plate 21 will rest on the horizontal plate 241. When the rotating rod 1 rotates to the left, the right side of the support plate 21 will first drive the pressure-bearing member 24 to rotate along the rotation axis, such as Figure 10 As shown, when the right side of the support piece 21 is separated from the rotating opening, the left side of the support piece 21 will press on the horizontal plate 241, so that the support piece 21 is reset. At this time, the rotating rod 1 rotates to the horizontal position, and the support piece 21 is still pressed on the horizontal plate 241, as shown in FIG. Figure 10 As shown, the principle is opposite during reset.

[0065] With the above-mentioned structural design, when the rotating rod 1 is subjected to excessive pressure, the pressure-bearing member 24 is pressed downward via the support plate 21. At this time, the pressure-bearing plate 243 abuts against the housing 2 via the vertical plate 242, thereby dispersing the pressure of the rotating rod 1 on the transmission shaft 20. This allows the crossbar 22 of this lifting transmission structure to withstand a higher weight.

[0066] A gap is left between the horizontal plate 241 and the shell 2 to prevent the pressure-bearing member 24 from becoming a purely rigid structure, thereby increasing the adaptability of the pressure-bearing member 24 and the supporting sheet 21 and reducing production difficulty.

[0067] In one embodiment, a damping device 25 is provided at the bottom of the external pull rod 23, and the damping device 25 includes:

[0068] An outer tube 251 whose top is threadedly connected to the bottom of the external pull rod 23;

[0069] An inner tube 252 disposed within the outer tube 251 and threadedly connected to the bottom of the external pull rod 23;

[0070] A retaining ring 253 provided at the bottom of the inner tube 252 and having a plurality of through holes;

[0071] A counterweight handle 254 is provided below the outer tube 251. An extension rod of the counterweight handle 254 passes through the outer tube 251 and the retaining ring 253 and extends into the interior of the inner tube 252. A slider 255 is provided on the extension rod. A third elastic member 256 is provided between the slider 255 and the retaining ring 253.

[0072] Several pressing blocks 257 are arranged on the side wall of the inner tube 252. The upper pressing block is located above the slider 255, and the lower pressing block is located below the slider 255. The upper and lower pressing blocks are symmetrically arranged in an upper and lower direction. A connecting column is provided on the pressing block 257. A mounting groove is provided on the outer wall of the inner tube 252. The pressing block 257 is connected to the mounting groove through the connecting column. The connecting columns of the upper and lower pressing blocks are arranged opposite to each other. A groove is provided on the side wall of the pressing block 257 located outside the inner tube 252. An annular elastic member 258 is provided on the upper or lower pressing block arranged along the same circumference, and the annular elastic member 258 connects the pressing blocks 257 located on the same circumference through the groove.

[0073] A positioning ring 259 is provided between the outer tube 251 and the inner tube 252 , and an inner wall of the positioning ring 259 is provided with a movable groove adapted to the connecting column.

[0074] The working principle and beneficial effects of the above technical solution are as follows: Because the external pull rod 23 is arranged on the cross bar 22, in order to reduce the force exerted by the external pull rod 23 on the cross bar 22, a damping device 25 is additionally provided at the bottom of the external pull rod 23.

[0075] The side wall of the inner tube 252 is provided with two circles of grooves symmetrically along the circumference, such as Figure 16 As shown, the groove is provided with a semi-cylindrical movable groove adapted to the connecting column, and the inner wall of the positioning ring 259 is also symmetrically provided with a semi-cylindrical movable groove. The connecting column of the pressure block 257 can be placed in the cylinder formed by the two movable grooves, so that the pressure block 257 can rotate with the connecting column as the rotation center axis. The outer wall of the pressure block 257 on the same circumference is also provided with an annular elastic member 258. When the outer wall of the pressure block 257 abuts against the inner wall of the outer tube 251, the inner wall of the pressure block 257 is still located inside the inner tube 252 to limit the slider 255.

[0076] Taking the example of pulling down the external pull rod 23, the counterweight handle 254 is pulled downward, thereby driving the slider 255 downward through the extension rod. When the slider 255 moves downward, it contacts the inner wall of the lower pressing block. Then, under the action of the slider 255, the lower pressing block expands toward the outer tube 251, stretching the annular elastic member 258 and finally engaging with the inner wall of the lower pressing block, driving the external pull rod 23 downward. When the handle is released, the slider 255 returns to its original position under the action of the annular elastic member 258. The same principle applies when pushing up the external pull rod 23.

[0077] Through the above-mentioned structural design, when the external pull rod 23 is pulled down or pushed up, the slider 255 will first drive the external pull rod 23 to move through the pressure block 257. The pressure block 257 can slowly release the stress and transfer it to the external pull rod 23, and then slowly transfer it to the cross bar 22 through the external pull rod 23, so that the force on the cross bar 22 can be slowly transitioned. The damping device 25 can have a deceleration effect similar to the gas pressure support 11. In addition to making it easier for users to pull down the hanger, the counterweight handle 254 can also act as a damper counterweight when hanging heavy clothes, thereby reducing the vibration generated by the cross bar 22 when hanging heavy clothes and increasing the service life of the cross bar 22.
