Description

Technical Field

[0001] This utility model relates to the field of sliding rail technology, specifically an electric sliding rail that can be switched between manual and automatic operation. Background Technology

[0002] Sliding rails are used for drawers or similar pull-out sliding rails and are suitable for furniture, filing cabinets, kitchen cabinets, bathroom cabinets, electrical cabinets, heavy-duty refrigerators, etc.

[0003] The existing sliding rail includes a fixed rail and a sliding rail that are slidably connected in sequence. The fixed rail is installed on the cabinet body, and the sliding rail is installed on the drawer assembly.

[0004] The sliding rail is opened and closed by a power mechanism for ease of use. This power mechanism includes a drive motor, a drive shaft that can be driven by the drive motor and thus rotate, a coupling, and a screw that can be driven by the drive shaft via the coupling and thus rotate. The coupling has: a driven element, an actuating element that can be driven by the drive shaft via rotation of the drive shaft and thus rotate about an actuating rotation axis and has at least one first actuating area, and a coupling element having at least one second actuating area corresponding to the first actuating area and capable of translating relative to the driven element along the actuating rotation axis between at least one disengaged position and at least one engaged position. In the disengaged position, the coupling element is disengaged from the driven element; in the engaged position, the coupling element is engaged with the driven element.

[0005] However, the electric slide rails with the above-mentioned structure have the following shortcomings in practical applications:

[0006] 1) The complex structure reduces the drawer's capacity and requires high precision in assembly; otherwise, the product's performance will be affected.

[0007] 2) Since the rotation of the motor's drive shaft is between the operating element and the coupling element, when the motor is powered off, manually pushing and pulling the drawer still requires overcoming the motor's torque, which is laborious and will affect the service life of the electric slide rail. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electric slide rail that can be switched between manual and automatic operation. It has a simple structure, is easy to assemble, reduces the volume occupied by the drawer, and can freely switch between electric and manual push-pull drawer modes using a mechanical method. It is easy to operate, has high synchronization performance, and ensures the quality of product use.

[0009] The objective of this invention is achieved as follows: an electric slide rail that can be switched between manual and automatic operation includes two symmetrically distributed sets of slide rail assemblies and a synchronous power source for driving the slide rail assemblies to operate synchronously. The synchronous power source includes a motor, a synchronous rod, a synchronous main gear set, and synchronous gears. The synchronous gears are respectively installed on the fixed rails of the slide rail assemblies. One end of the synchronous main gear set is rotatably connected to the sliding rail of the slide rail assembly, and the other end of the synchronous main gear set is installed on one end of the synchronous rod. A synchronous driven gear is installed on the other end of the synchronous rod. The synchronous main gear set and the synchronous driven gear are respectively meshed with the synchronous gears. A clutch is installed between the motor and the synchronous main gear set. The input end of the clutch is linked to the output end of the motor when the motor rotates forward, or the input end of the clutch is separated from the output end of the motor when the motor rotates in reverse. The output end of the clutch is connected to the synchronous main gear set.

[0010] Based on the above optimization, the synchronous main gear set includes a synchronous gear housing and a first synchronous gear and a second synchronous gear rotatably connected within the synchronous gear housing. The clutch is installed inside the synchronous gear housing, and the motor is installed outside the synchronous gear housing. The synchronous gear housing is installed on the sliding rail of the slide rail assembly. The output end of the clutch is connected to the first synchronous gear. The second synchronous gear is clamped at one end of the synchronous rod. The input end of the second synchronous gear is meshed with the first synchronous gear, and the output end of the second synchronous gear is conditionally meshed with the corresponding synchronous gear.

[0011] Based on the above optimization, the second synchronous gear includes a synchronous connecting part, a synchronous large tooth part, and a synchronous small tooth part. The synchronous connecting part is clamped on one end of the synchronous rod. The synchronous small tooth part and the synchronous large tooth part are distributed on the synchronous connecting part. The synchronous small tooth part is meshed with the first synchronous gear, and the synchronous large tooth part is meshed with the corresponding synchronous tooth.

[0012] Based on the above optimization, the synchronous gear housing is provided with a mounting plate, and the sliding rail is provided with mounting ears for mounting to mate with the mounting plate.

[0013] Based on the above optimization, the synchronous main gear set also includes a detection mounting group for real-time detection of the meshing at the synchronous gear condition position. The detection mounting group includes a Hall circuit board and a magnetic ring. The Hall circuit board is installed on the outside of the synchronous gear housing, and the magnetic ring is snapped onto the synchronous connection part of the second synchronous gear.

[0014] Based on the above optimization, the two ends of the synchronizing rod are respectively provided with a synchronizing connection part for synchronizing with the second synchronizing gear and the synchronizing connection part of the synchronizing driven gear for mounting.

[0015] Based on the above optimization, the clutch includes a clutch input shaft connected to the output shaft of the motor and a clutch output shaft connected to the first synchronous gear. A linkage retaining member is installed between the clutch input shaft and the clutch output shaft to be squeezed when the motor rotates forward to make the clutch input shaft and the clutch output shaft linked together, or to separate the clutch input shaft and the clutch output shaft when the motor rotates backward.

[0016] The advantages of this utility model are:

[0017] 1) The structure of this synchronous power source, including the motor, synchronizing rod, synchronizing main gear set, and synchronizing gear condition, allows the motor to rotate forward, driving the clutch to rotate. This clutch, in turn, drives the synchronizing main gear set. Under the action of the synchronizing rod, the synchronizing main gear set and the synchronizing driven gear mesh on their corresponding synchronizing gear conditions. This electrically pushes the sliding rail along the fixed rail, opening or closing the drawer in electric mode. When the drawer is closed, the motor reverses to the designated position, disengaging the clutch and motor to open or close the drawer manually. The structure is simple, easy to assemble, allows for free mode switching, is convenient to operate, flexible in use, and has high synchronous operation, ensuring product quality.

[0018] 2) The clutch with this structure can separate from the motor after the motor reverses to a specified position, realizing automatic conversion from electric mode to manual mode push-pull. It simplifies the structure, provides mechanical control, is easy to operate, is suitable for use in different products, and has high practicality. Attached Figure Description

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] According to the appendix Figures 1 to 6 As shown, the electric slide rail for manual / automatic switching of this utility model includes two symmetrically distributed slide rail assemblies 1 and a synchronous power source for driving the slide rail assemblies 1 to operate synchronously. The synchronous power source includes a motor 2, a synchronous rod 3, a synchronous main gear set 4, and synchronous gear condition 5. The synchronous gear condition 5 is respectively installed on the fixed rail of the slide rail assembly 1. One end of the synchronous main gear set 4 is rotatably connected to the sliding rail of the slide rail assembly 1, and the other end of the synchronous main gear set 4 is installed on one end of the synchronous rod 3. The other end of the synchronous rod 3 is equipped with a synchronous driven gear component 7. The synchronous main gear set 4 and the synchronous driven gear component 7 are respectively meshed with the synchronous gear condition 5. A clutch 6 is installed between the motor 2 and the synchronous main gear set 4. The input end of the clutch 6 is linked to the output end of the motor 2 when the motor 2 rotates forward, or the input end of the clutch 6 is disengaged from the output end of the motor 2 when the motor 2 rotates in reverse. The output end of the clutch 6 is connected to the synchronous main gear set 4.

[0027] The structure of this synchronous power source, consisting of motor 2, synchronous rod 3, synchronous main gear set 4, and synchronous gear condition 5, allows motor 2 to rotate forward, driving clutch 6 to rotate. Clutch 6 then rotates synchronous main gear set 4 in conjunction with the synchronous rod 3. Under the action of synchronous rod 3, synchronous main gear set 4 and synchronous driven gear 7 mesh with their corresponding synchronous gear condition 5, thus electrically pushing the sliding rail along the fixed rail to open or close the drawer. When the drawer is closed, motor 2 reverses to the designated position, disengaging clutch 6 and allowing manual opening or closing of the drawer. The structure is simple, easy to assemble, allows for free mode switching, is convenient to operate, flexible in use, and has high synchronous operation, ensuring product quality.

[0028] Reference Figures 1 to 6 As shown, further detailed, the synchronous main gear set 4 includes a synchronous gear housing 41 and a first synchronous gear 42 and a second synchronous gear 43 rotatably connected within the synchronous gear housing 41. The clutch 6 is installed inside the synchronous gear housing 41, and the motor 2 is installed outside the synchronous gear housing 41. The synchronous gear housing 41 is mounted on the sliding rail of the slide rail assembly 1. The output end of the clutch 6 is connected to the first synchronous gear 42. The second synchronous gear 43 is engaged at one end of the synchronous rod 3. The input end of the second synchronous gear 43 meshes with the first synchronous gear 42, and the output end of the second synchronous gear 43 meshes with the corresponding synchronous gear condition 5.

[0029] In practical applications, the second synchronizing gear 43 includes a synchronizing connection part 431, a synchronizing large tooth part 432, and a synchronizing small tooth part 433. The synchronizing connection part 431 is mounted on one end of the synchronizing rod 3. The synchronizing small tooth part 433 and the synchronizing large tooth part 432 are distributed on the synchronizing connection part 431. The synchronizing small tooth part 433 is meshed with the first synchronizing gear 42, and the synchronizing large tooth part 432 is meshed with the corresponding synchronizing tooth 5.

[0030] The synchronous main gear set 4, using this structure, operates with the output shaft of motor 2 rotating forward and connecting to clutch 6 during motor 2 operation. This drives the synchronous main gear set 4, causing the first synchronous gear 42 to drive the second synchronous gear 43. This, in turn, synchronizes the rotation of the synchronous connecting rod, causing the second synchronous gear 43 to mesh synchronously with the driven gear on the corresponding synchronous teeth 5. This achieves synchronous sliding of the sliding rails of the two sets of slide rail assemblies 1, resulting in synchronous opening and closing. This effectively enhances transmission stability and operational synchronization, reduces noise generation, and is reliable and practical.

[0031] Reference Figures 1 to 6 As shown in the figure, further detailed, the clutch 6 includes a clutch input shaft 61 connected to the output shaft of the motor 2 and a clutch output shaft 62 connected to the first synchronous gear 42. A linkage retaining member 63 is installed between the clutch input shaft 61 and the clutch output shaft 62 for being squeezed when the motor 2 rotates forward to make the clutch input shaft 61 and the clutch output shaft 62 linked together, or for being separated when the motor 2 rotates in reverse to make the clutch input shaft 61 and the clutch output shaft 62 separate.

[0032] In this clutch 6 structure, the motor 2 drives the clutch input shaft 61 to rotate forward. At this time, the linkage retainer 63 rotates accordingly, pressing between the clutch input shaft 61 and the clutch output shaft 62, causing them to be linked and connected. This rotation of the clutch output shaft 62 causes the synchronous main gear set 4 and synchronous driven gear 7 at both ends of the synchronous rod 3 to mesh synchronously on the synchronous gear condition 5, thereby moving the sliding rail. When the motor 2 reverses, the linkage retainer 63 rotates accordingly, disengaging the clutch input shaft 61 from the clutch output shaft 62, thus achieving manual / automatic switching. This mechanical switching method is flexible and enhances the product's performance.

[0033] Reference Figures 1 to 6 As shown in the figure, in further detail, the synchronous gear housing 41 is provided with a mounting plate 44, and the sliding rail is provided with mounting ears for mounting to mate with the mounting plate 44.

[0034] The synchronizing rod 3 has a locking end 31 at both ends for synchronizing with the second synchronizing gear 43 and the synchronizing driven gear 7.

[0035] The synchronous power source with this structure is simple, easy to assemble, has high transmission stability, and can improve synchronous operation, thus ensuring the quality of product use.

[0036] In the optimized scheme, the synchronous main gear set 4 also includes a detection mounting group for real-time detection of meshing at the synchronous gear condition 5 position. The detection mounting group includes a Hall circuit board 8 and a magnetic ring 9. The Hall circuit board 8 is installed on the outside of the synchronous gear housing 41, and the magnetic ring 9 is snapped onto the synchronous connection part 431 of the second synchronous gear 43.

[0037] The Hall circuit board 8 and magnetic ring 9 of the detection and mounting assembly in this structure can be used to detect the movement position of the slide rail in real time, ensuring stable operation and reliable practicality.

[0038] The above specific embodiments are only specific implementations of the present utility model with better effects. Any structure that is the same as or equivalent to the electric slide rail for manual / automatic switching of the present utility model is within the protection scope of the present utility model.
