Description

Technical Field

[0001] The invention relates to the technical field of slide rail devices, and in particular to a synchronous electric slide rail. Background Art

[0002] The slide rail can carry a large load while requiring only a small amount of force to reciprocate along a linear track.

[0003] Existing synchronous slide rails lack power and their transmission systems. During the whole process, manpower needs to continuously provide pulling or pushing force so that the guide rail can move until it is fully opened or fully closed. Because manpower needs to continuously provide pulling or pushing force, the guide rail can move until it is fully opened or fully closed. This leads to many inconveniences for users in some scenarios. For example, when a user needs to open a drawer with both hands full of items, or when an older user bends over to take items out of the drawer, it is difficult for the user to continue pulling and pulling, and the slide rail cannot be fully opened or closed, resulting in a poor user experience. The disadvantage is that for large drawers or when the built-in items in the drawer are heavy, the force required to push and pull the drawer is large, the operation is more laborious, and the slide rail is easily damaged, reducing the service life of the product.

[0004] In the prior art, drawers equipped with slide rails are mostly operated manually, that is, the drawers are opened or closed by hand pulling or hand pushing. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a synchronous electric slide rail.

[0006] In order to solve the above technical problems, the present invention provides a synchronous electric slide rail, comprising:

[0007] A track mechanism, the track mechanism comprising a pair of parallel and spaced slide rail assemblies, the slide rail assembly comprising a fixed slide rail and a movable slide rail installed therein and movable relative thereto, the movable slide rail comprising an inner rail;

[0009] A driving mechanism, wherein the driving mechanism is drivingly connected to the synchronous transmission mechanism, and the output gear of the driving mechanism drives the driven gear on the connecting rod shaft to rotate together;

[0010] The control mechanism comprises a touch switch and a controller, and the controller is electrically connected to the touch switch and the driving mechanism respectively.

[0011] Furthermore, the control mechanism also includes a limit switch, the touch switch is arranged on the door wall of the drawer, the controller is arranged at the rear of the drawer, the limit switch is arranged on the fixed slide rail, and the limit switch is electrically connected to the controller.

[0012] Furthermore, the controller controls the driving mechanism to drive the linkage gear along the rack to drive the movable slide rail to move according to the signal sent by the touch switch, and controls the driving mechanism to stop according to the signal sent by the limit switch, thereby electrically opening or closing the drawer.

[0013] Furthermore, the rack and the movable slide rail are adjacent to each other side by side on the fixed slide rail.

[0014] Furthermore, the inner rail is installed on the side wall adjacent to the drawer and the cabinet, and the fixed slide rail is installed on the side wall adjacent to the cabinet and the drawer.

[0015] Furthermore, the driven gear is fixedly connected to the connecting rod shaft.

[0016] Furthermore, the movable slide rail also includes a middle rail, and the middle rail is arranged between the fixed slide rail and the inner rail to connect the fixed slide rail and the inner rail.

[0017] Furthermore, the driving mechanism is a motor.

[0018] The implementation of the present invention has the following beneficial effects:

[0019] The motor of the present invention is installed backwards, so the drawer is not easy to tilt forward when it is opened, which is beneficial to enhance the sliding stability of the drawer;

[0020] The quick-release structure of the synchronous transmission mechanism not only strengthens the synchronous operation of the slide rail components, but also realizes rapid assembly, convenient operation, and easy maintenance and replacement. Under a load of 35KG, after 50,000 pull-and-pull slides back and forth, the electric slide rail slides normally without deformation, stagnation, or abnormal noise, ensuring the quality of the slide rail.

[0021] The driving mechanism cooperates with the synchronous transmission mechanism to make the transmission more stable, reduce the noise, and improve the product experience;

[0022] The touch switch arranged on the wall of the drawer door transmits the signal to the controller, and the controller controls the motor to drive the linkage gear along the rack to drive the slide rail assemblies on both sides to move synchronously, thereby realizing the electronically controlled opening or closing of the drawer, which is convenient to operate and the opening or closing of the drawer is stable and reliable;

[0023] The two ends of the connecting rod shaft are supported and positioned with racks, which can make the motor drive the connecting rod shaft to rotate more smoothly and reliably, thereby avoiding the imbalance of transmission force caused by the motor being offset at one end of the connecting rod shaft, which is beneficial to improving the stability of the drawer when it is electrically pushed and pulled, and reducing noise.

DETAILED DESCRIPTION

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-6 A synchronous electric slide rail is shown, comprising: a track mechanism 1, a synchronous transmission mechanism 2, a driving mechanism 3 and a control mechanism 4.

[0033] like Figure 1-4As shown, the track mechanism 1 includes a pair of parallel and spaced rail assemblies 11, the rail assembly 11 includes a fixed rail 111 and a movable rail 112 installed therein and movable relative thereto, the movable rail 112 includes a middle rail 1121 and an inner rail 1122, the middle rail 1121 is arranged between the fixed rail 111 and the inner rail 1122, and connects the fixed rail 111 and the inner rail 1122. The inner rail 1122 is installed on the side wall of the drawer 5 adjacent to the cabinet, the fixed rail 111 is installed on the side wall of the cabinet adjacent to the drawer 5, and the middle rail 1121 connects the inner rail 1122 and the fixed rail 111.

[0034] like Figure 2 , 3 As shown in Figure 5, the synchronous transmission mechanism 2 includes a connecting rod assembly 21 connected between the slide rail assemblies 11, and the connecting rod assembly 21 includes a connecting rod shaft 211 and a linkage gear 212 arranged at both ends of the connecting rod shaft 211. A rack 1111 is arranged on the fixed slide rail 111, and the linkage gear 212 is rotatably arranged on the inner rail 1122 and meshes with the rack 1111; preferably, the rack 1111 and the movable slide rail 112 are adjacent to each other side by side on the fixed slide rail 111. The quick-release structure of the synchronous transmission mechanism 2 not only strengthens the synchronous operation of the slide rail assembly 11, but also realizes rapid assembly, convenient operation, and easy maintenance and replacement. Under a load of 35KG, after 50,000 pull-and-pull slides back and forth, the electric slide rail still slides normally without deformation, jamming, or abnormal noise, ensuring the quality of the slide rail. The two ends of the connecting rod shaft 211 are supported and positioned by racks 1111, which can make the motor drive the connecting rod shaft 211 to rotate more smoothly and reliably, thereby avoiding the imbalance of transmission force caused by the motor being biased at one end of the connecting rod shaft 211, which is beneficial to improving the stability of the drawer 5 when it is pushed and pulled electrically and reducing noise.

[0035] like Figure 2 , 3 As shown in Figures 5 and 6, the drive mechanism 3 is in transmission connection with the synchronous transmission mechanism 2, and the output gear 31 of the drive mechanism 3 drives the driven gear 22 on the connecting rod shaft 211 to rotate together, and the driven gear 22 is fixedly connected to the connecting rod shaft 211. Preferably, the drive mechanism 3 is a motor. The motor is installed backward, and the drawer 5 is not easy to tilt forward when it is opened, which is conducive to enhancing the sliding stability of the drawer 5. The drive mechanism 3 cooperates with the synchronous transmission mechanism 2 to make the transmission more stable, reduce the generation of noise, and improve the user experience of the product.

[0036] like Figure 2-6As shown, the control mechanism 4 includes a touch switch 41, a controller 42 and a limit switch 43, and the controller 42 is electrically connected to the touch switch 41, the limit switch 43 and the driving mechanism 3 respectively. The touch switch 41 is arranged on the door wall of the drawer 5, the controller 42 is arranged at the rear of the drawer 5, and the limit switch 43 is arranged on the fixed slide rail 111. The controller 42 controls the driving mechanism 3 to drive the linkage gear 212 along the rack 1111 to drive the movable slide rail 112 to move according to the signal received from the touch switch 41, so that the drawer 5 is electrically controlled to open or close. When the touch switch 41 sends a trigger signal, the controller 42 controls the motor to rotate forward, and when the trigger signal is sent again, the controller 42 controls the motor to reverse; after the drawer 5 is fully opened or closed, the limit switch 43 contacts the movable slide rail 112 and generates a signal, and the controller 42 controls the motor to stop according to the limit signal of the limit switch 43. The touch switch 41 arranged on the door wall of the drawer 5 transmits a signal to the controller 42, and the controller 42 controls the motor to drive the linkage gear 212 along the rack 1111 to drive the slide rail assemblies 11 on both sides to move synchronously, thereby realizing the electronically controlled opening or closing of the drawer 5, which is convenient to operate and the opening or closing of the drawer 5 is stable and reliable.
