Technical Field

[0001] This utility model relates to the field of mechanical transmission, and more specifically, it relates to a drawer-type electrical device. Background Technology

[0002] In the existing technology, the drawer unit of drawer-type electrical equipment is usually pulled out and pushed in manually, which is cumbersome and inefficient. To address this, an electric drive can be used to simplify the operation. However, if the electric equipment malfunctions during operation, the malfunction will adversely affect the equipment maintenance process, thereby reducing the overall reliability and ease of use. Utility Model Content

[0003] To address the shortcomings of existing technologies, a drawer-type electrical device is provided, which has the function of manually and electrically controlling the drawer cabinet to be pulled out or pushed out.

[0004] To achieve the above objectives, the following technical solution is provided: a drawer-type electrical device, comprising a cabinet, a drawer unit, and a drive structure; The drawer unit is slidably connected to the cabinet body; The drive structure includes a driver, a drive component, a transmission assembly, and a terminal component; The terminal is connected to the cabinet; The driver drives the terminal piece through a transmission component to pull the drawer unit out or push it into the cabinet. The drive component is provided with a drive groove for the tool to extend into; The tool extends into the drive slot to control the drive component to drive the terminal component, thereby causing the drawer unit to be pulled out or pushed into the cabinet.

[0005] In a further optimization of this utility model, the transmission assembly includes a first output gear, a second output gear, a transmission gear set, and a clutch; The driver drives the first output gear to rotate; The first output gear drives the transmission gear set to rotate; The transmission gear set is connected to the second output gear via a clutch, and drives the second output gear to rotate; The second output gear is connected to the terminal component and drives the terminal component to rotate; When the driving component drives the terminal component to rotate, the power transmission between the terminal component and the transmission gear set is cut off by the clutch.

[0006] In a further optimization of this utility model, the drawer unit is provided with a through hole for a tool to extend into the drive groove and a baffle that is slidably connected to the drawer unit; The baffle moves on the drawer unit to open and close the through hole.

[0007] A further optimization of this utility model is that a limit switch is provided on the travel path of the drawer unit corresponding to the opening and closing through hole of the baffle; The baffle is provided with a trigger protrusion adapted to the limit switch; When the baffle moves, it triggers a protrusion-triggered limit switch to control the driver switch.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0013] Reference Figure 1-2 As shown, a drawer-type electrical device includes a cabinet, a drawer unit 1, and a drive structure 2; Drawer unit 1 is slidably connected to the cabinet body; The drive structure 2 includes a driver 21, a drive component 22, a transmission assembly 23, and a terminal component 24; Terminal 24 is connected to the cabinet; The drive 21 drives the terminal piece 24 through the transmission assembly 23 to pull the drawer unit 1 out or push it into the cabinet. The drive unit 22 is provided with a drive groove 221 for the tool to extend into; The tool extends into the drive slot 221 and controls the drive component 22 to drive the terminal component 24, thereby causing the drawer unit 1 to be pulled out or pushed into the cabinet.

[0014] like Figure 2 As shown, when the driver 21 (which can be a DC motor or an AC motor) is started, it transmits power to the terminal 24 through the transmission component 23. The terminal 24 is connected to the cabinet, thereby driving the drawer unit 1 to slide relative to the cabinet, realizing electric pull-out or push-in operation, and improving operating efficiency. Alternatively, a tool can be inserted into the drive groove 221 of the drive component 22, and the tool can drive the drive component 22 to rotate, thereby driving the rotation of the terminal component 24, so as to realize the manual control of the drawer unit 1 to be pulled out or pushed in. The terminal component 24 can be connected to a lead screw or a push-pull rod. If the terminal component 24 is connected to a lead screw, the driver 21 or the driver component 22 drives the terminal component 24 to rotate. The rotation of the terminal component 24 drives the lead screw to rotate. The drawer unit 1 is fixedly connected to the nut seat. As the lead screw rotates, the nut seat is restricted from rotating by the drawer unit 1. Thus, the nut seat drives the drawer unit 1 to move on the lead screw, realizing the function of pulling out or pushing in the drawer unit 1. Compared with the prior art, the drive slot 221 provided in the drive component 22 allows tools (such as Allen wrenches) to be inserted. When the drive 21 fails, the tool directly drives the drive component 22, controls the terminal component 24 to rotate, and manually drives the drawer unit 1 to move. This electric and manual dual-mode design ensures that the equipment can still be operated in the event of failure, improving reliability and ease of use.

[0015] Preferably, the transmission assembly 23 includes a first output gear 231, a second output gear 232, a transmission gear set 233, and a clutch 234; The driver 21 drives the first output gear 231 to rotate; The first output gear 231 drives the transmission gear set 233 to rotate; The transmission gear set 233 is connected to the second output gear 232 via the clutch 234, and drives the second output gear 232 to rotate; The second output gear 232 is connected to the terminal piece 24 and drives the terminal piece 24 to rotate; When the driving component 22 drives the terminal component 24 to rotate, the power transmission between the terminal component 24 and the transmission gear set 233 is cut off by the clutch 234.

[0016] The driver 21 drives the first output gear 231 to rotate, the first output gear 231 drives the transmission gear set 233, the transmission gear set 233 is connected to the second output gear 232 through the clutch 234, driving the second output gear 232 to rotate, and the second output gear 232 finally drives the terminal piece 24 to rotate, thereby realizing the electric operation of the drawer unit 1. This gear transmission structure provides stable power transmission and speed ratio adjustment. The drive unit 21 and the terminal unit 24 typically rotate at different speeds, requiring the transmission gear set 233 to use differential gears to balance the rotational speeds on both sides. like Figure 2 As shown, during manual operation, the tool extends into the drive slot 221 to drive the drive component 22, which directly drives the terminal component 24 to rotate. The terminal component 24 is connected to the second output gear 232. The rotation of the drive component 22 will drive the second output gear 232 to rotate. At this time, the clutch 234 needs to automatically cut off the power transmission between the transmission gear set 233 and the second output gear 232 to prevent the transmission gear set 233 from driving the driver 21 in reverse during manual operation, thus avoiding damage to the driver 21. At the same time, it ensures smooth manual operation and improves the safety of the equipment. Clutch 234 can be an overrunning clutch 234, a friction clutch 234, or an electromagnetic clutch 234, etc., and must at least achieve unidirectional transmission function.

[0017] Preferably, the drawer unit 1 is provided with a through hole 11 for a tool to extend into the drive groove 221 and a baffle 12 that is slidably connected to the drawer unit 1; The baffle 12 moves on the drawer unit 1 to open and close the through hole 11.

[0018] like Figure 1 As shown, when the drive unit 22 is installed inside the drawer unit 1, a through hole 11 needs to be provided to allow the tool to be inserted into the drive slot 221 for operation. like Figure 2 The baffle 12 shown is slidably connected to the drawer unit 1. The through hole 11 can be opened or closed by moving the baffle 12. The sliding connection method can be that the drawer unit 1 is provided with a sliding groove, and the two sides of the baffle 12 are installed in the sliding groove to achieve the sliding connection. When manual operation is required, the movable baffle 12 opens the through hole 11, and the tool is inserted into the drive component 22 to realize manual control of the drawer unit 1. When manual operation is not required, close the through hole 11 to prevent dust and foreign objects from entering the drive structure 2, reduce component wear and failure risk, thereby extending equipment life and improving safety, while also avoiding misoperation.

[0019] Preferably, a limit switch 13 is provided on the travel path of the drawer unit 1 corresponding to the opening and closing through hole 11 of the baffle 12; The baffle 12 is provided with a trigger protrusion that is compatible with the limit switch 13; When the baffle 12 moves, it triggers the protrusion-triggered limit switch 13 to control the switch of the driver 21.

[0020] like Figure 2 As shown, the limit switch 13 is set on the travel path of the baffle 12, and the trigger protrusion is set on the baffle 12; When the baffle 12 moves to the position of opening the through hole 11, it triggers the protrusion trigger limit switch 13. The limit switch 13 controls the driver 21 to close, preventing the electric drive from being accidentally started during manual operation, and avoiding equipment damage or personal injury due to misoperation. When the baffle 12 moves to the position of closing the through hole 11, it triggers the protrusion to leave the limit switch 13, and the driver 21 can start normally, realizing the automatic recovery of electric operation. This design improves the safety and automation level of the equipment. Limit switch 13 can be mechanical, inductive or magnetic, etc. The trigger protrusion can be a protrusion, magnet or metal sheet, which cooperates with limit switch 13 through contact, induction or magnetic attraction. Limit switch 13 and driver 21 can be connected by circuit to realize the transmission of switching signal.

All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
