[0026] In the following description, all concepts related to directionality or orientation such as up, down, left, right, front and back are based on the positions shown in the corresponding drawings. They are only used to facilitate the description of the technical solution provided by the utility model and simplify the description in conjunction with the drawings, and therefore cannot be understood as a special limitation on the technical solution provided by the utility model.

[0027] The utility model provides a mounting structure for an external electric drive device for a drawer seat, comprising a first positioning and connecting component 4 and a locking component 5;

[0028] The electric drive device 3 and the drawer seat 1 are connected in this way, and a first positioning connection component 4 is arranged between the electric drive device 3 and the drawer seat 1. The locking component 5 is arranged on the electric drive device 3 and can move between a first position and a second position. When the locking component 5 moves from the first position to the second position, the locking component 5 and the other end of the first positioning connection component 4 are snap-fitted to achieve rapid locking of the installation position of the electric drive device 3 so that the electric drive device 3 and the first positioning connection component 4 are relatively fixed.

[0029] Specifically, the drawer seat 1 is provided with a first connection hole 11, the electric drive device 3 is provided with a second connection hole 31, and the two ends of the first positioning connection component 4 respectively realize the abutment between the drawer seat 1 and the electric drive device 3 through the first connection hole 11 and the second connection hole 31. Figure 3 The electric drive device 3 and the drawer seat 1 are arranged close to each other.

[0030] The first positioning connection assembly 4 includes a first nut 41 and a first positioning connection bolt 42. One end of the first positioning connection bolt 42 passes through the first connection hole 11 and cooperates with the first nut 41 to achieve a fixed connection on the drawer seat 1. The other end of the first positioning connection bolt 42 passes through the second connection hole 31 and locks the installation position of the electric drive device 3 through the locking assembly 5.

[0031] Specifically, the locking assembly 5 includes a locking member 51 and an elastic member 52. The locking member 51 is arranged on the electric drive device 3, and the elastic member 52 is arranged between the locking member 51 and the electric drive device 3, and is used to provide an elastic force to drive the locking member 51 to quickly reset, that is, to quickly cross the dead point position from the first position to reset to the second position or to quickly cross the dead point position from the second position to reset to the first position.

[0032] Further, a clamping groove 421 is provided at one end of the first positioning connection bolt 42 facing the electric drive device 3. The locking member 51 is engaged with the clamping groove 421 to lock the installation position of the electric drive device 3. Specifically, the locking member 51 and the electric drive device 3 are cooperated as follows: a clamping portion 511 is provided on the locking member 51, and the clamping portion 511 is engaged with the clamping groove 421 to realize the positioning and locking of the first positioning connection bolt 42, that is, the locking member 51 is located at the second position. The clamping portion 511 is set to a shape adapted to the clamping groove 421, and is set to a semi-circular arc shape in this embodiment.

[0033] The locking member 51 is arranged on the electric drive device 3 as follows: an installation hole 512 is provided on the locking member 51, and the locking member 51 is rotatably arranged on the electric drive device 3 through the installation hole 512. Specifically, the locking member 51 is rotatably arranged on the electric drive device 3 by passing a fastener through the installation hole 512 and a corresponding hole provided on the electric drive device 3. Of course, the locking member 51 can also have other installation methods. For example, slidingly arranging on the electric drive device 3 is also feasible, as long as the electric drive device 3 can be relatively fixed to the first positioning connection assembly 4.

[0034] Specifically, one end of the elastic member 52 is fixedly arranged on the hanging end 513 of the locking member 51, and the other end is arranged on the hanging portion 32 of the electric drive device 3. In this way, the locking member 51 has three position states: an unlocking position, a dead point position, and a locking position. An operation portion 514 is provided on the locking member 51 for receiving an external operation to cause the locking member 51 to rotate. In this embodiment, the operation portion 514 is a protrusion provided on the locking member 51, which can be separately arranged or integrally arranged, as long as it is convenient for operation. In this example, the elastic member 52 is a spring.

[0035] As Figure 9 described, further, the installation structure further includes a second positioning connection assembly 6 arranged in the same height direction as the first positioning connection assembly 4. One end of the second positioning connection assembly 6 is fixedly connected to the drawer seat 1, and the other end is passed through the electric drive device 3 to realize auxiliary positioning and installation of the electric drive device 3.

[0036] The second positioning and connecting component 6 includes a second nut 61 and a second positioning and connecting bolt 62. One end of the second positioning and connecting bolt 62 passes through the third connecting hole 13 and is fitted with the second nut 61 to achieve fixed connection on the drawer base 1. The other end of the second positioning and connecting bolt 62 passes through the fourth connecting hole 33, and the installation position of the electric driving device 3 is further locked through the locking component 5, that is, it does not rotate in the plane direction. On the drawer base 1, the above-mentioned locking component 5 can also be provided beside the other end of the second positioning and connecting bolt 62. Or it is also feasible to provide a circlip or a locking nut at the other end of the second positioning and connecting bolt 62. The first positioning and connecting component 4 and the second positioning and connecting component 6 have the same structure. Through the first positioning and connecting component 4 and the second positioning and connecting component 6, the relative fixation of the electric driving device 3 on the drawer base 1 can be achieved. For better fixed installation, the installation structure further includes a fastening and connecting component 7. The fastening and connecting component 7 includes a fastening and connecting shaft 71, a fastening and connecting screw 72, and a fixed connecting nut 73. One end of the fastening and connecting shaft 71 passes through the hole on the drawer base 1 and is fitted and connected with the fastening and connecting screw 72, and the other end passes through the hole on the electric driving device 3 and is fitted with the fixed connecting nut 73 to achieve the fastening connection between the electric driving device 3 and the drawer base 1. Among them, the fastening and connecting component 7 is not in the same height direction as the first positioning and connecting component 4 and the second positioning and connecting component 6, thus forming three-point positioning, and the installation is more reliable. In the above embodiment, the fixed connecting nut 73 can also be replaced by the locking component 5. Similarly, the fastening and connecting shaft 71 can be replaced by the first positioning and connecting component 4, and the fastening and connecting screw 72 can be replaced by the first nut 41. That is, multiple sets of the cooperation of the first positioning and connecting component 4 and the locking component 5 can be used to complete the relative fixation of the electric driving device 3 on the drawer base 1, and preferably three sets.

[0037] As Figures 6 - 8 shown, during the actual practical process, that is, when the operator rotates the locking member 51 from the first position direction towards the second position direction and exceeds the dead point position during the operation process, under the action of the elastic member 52, the locking member 51 can automatically reset to the second position direction, that is, the clamping portion 511 is engaged with the clamping groove 421. Similarly, when the locking member 51 rotates from the second position direction to the first position direction and exceeds the dead point position, it can also automatically reset to the first position under the action of the elastic member 52.

[0038] This embodiment provides a drawer-type switch, as Figure 1As shown in the figure, it includes a drawer base 1, a switch body 2 and an electric drive device 3. The electric drive device is connected to the drawer base using the above installation structure. The switch body 2 can move within the drawer base 1, thereby realizing the connection or separation between the switch body 2 and the drawer base 1. An indicating member (not shown in the figure) for indicating the position state of the switch body 2 by rotation is provided within the drawer base 1. The electric drive device 3 is installed on the outside of the drawer base 1. The described outside means that the electric drive device 3 is located outside the housing of the drawer base 1, rather than integrated inside the drawer base 1. Specifically, in combination with the attached drawings, the electric drive device 3 is installed on the outside in front of the drawer base 1, that is, in the direction facing the operator. The electric drive device 3 is used to drive the transmission system within the drawer base 1 to act, and then the transmission system drives the switch body 2 to move relative to the drawer base 1. The electric drive device 3 is a separate device, and it can realize the switching between the fixed state and the disassembled state with the drawer base 1. Usually, the electric drive device 3 is connected to a remote control handle, and the remote control handle can control the operation of the electric drive device 3. The electric drive device 3 also needs to be powered on, for example, by connecting through a plug. When the electric drive device 3 is in the disassembled state with the drawer base 1, it does not affect the normal operation of the drawer switch. It only requires manual operation when driving the switch body 2 to move within the drawer base 1.

[0039] The embodiments of the present utility model have been described in detail above in combination with the attached drawings. However, the present utility model is not limited to this. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the purpose of the present utility model.
