[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0039] This application provides an electric operating mechanism with a protective cover housing, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of this application. And in the following embodiments, each embodiment is described with its own emphasis. For parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0040] To solve the technical problem in the prior art that the gears inside the electric operating mechanism are exposed outside, resulting in an increased risk, an embodiment of this application provides an electric operating mechanism with a protective cover housing. The following will be elaborated in detail.

[0041] Such as Figures 2 to 7As shown, an electric operating mechanism with a protective housing includes

[0042] a frame, which includes an upper mounting plate 11, a lower mounting plate, and a plurality of connecting columns 12. Each connecting column 12 is disposed between the upper mounting plate 11 and the lower mounting plate 10;

[0043] a protective housing 2, which is installed on one side of the frame and is located between the upper mounting plate 11 and the lower mounting plate 10. The protective housing 2 laterally protects and shields the parts inside the frame on this side.

[0044] Both ends of the connecting column 12 are riveted or connected with nuts after passing through the mounting plate.

[0045] Specifically, as an optional implementation manner in this embodiment, as Figures 3 to 6 shown, at least two cylindrical columns 3 are provided on the inner side of the protective housing 2. A column hole 31 is opened in the cylindrical column 3, and the connecting column 12 passes through the cylindrical column 3 to mount the protective housing 2 on the frame.

[0046] In this embodiment, the cylindrical column 3 and the protective housing 2 are of an integral structure, and the protective housing 2 is integrally formed by injection molding.

[0047] Specifically, as an optional implementation manner in this embodiment, as Figures 3 to 6 shown, the protective housing 2 includes a front plate 21, a top plate 22, and a pair of side plates 23;

[0048] The front plate 21, the top plate 22, and the side plates 23 are of an integral structure;

[0049] The cylindrical column 3 is disposed on the inner surface of the front plate 21.

[0050] The integrally formed protective housing 2 is mounted on the frame through each connecting column 12.

[0051] After the electric operating mechanism is installed, one side thereof will face the operator, and the protective housing 2 is installed on this side of the frame to ensure the safety of the operator.

[0052] The length of the protective housing 2 is sufficient to cover the frame on this side.

[0053] Specifically, as an optional implementation manner in this embodiment, as Figure 3 shown, an arc groove is formed on the inner side of the protective housing 2, and this arc groove is used to be adapted to the driving motor 15.

[0054] Specifically, as an optional implementation manner in this embodiment, as Figures 2 to 6 shown, a pair of connection holes 42 are opened on the top plate 22. The micro switch 16 is located below the connection holes 42. After the connection bolts pass through the connection holes 42, they are connected to the micro switch 16 to fix the micro switch 16 below the top plate 22.

[0055] The microswitch 16 belongs to the parts in the electric operating mechanism. In the past, the microswitch 16 could only be installed on the frame, resulting in relatively limited installation of the microswitch 16. Now, with the addition of the protective cover 2, the microswitch 16 can be directly installed on the protective cover 2, providing a new structure for the installation of the microswitch 16 on the frame.

[0056] To improve the installation strength of the microswitch 16 on the protective cover 2, a pair of bosses 41 are provided on the top plate 22, and the connection holes 42 are opened in the bosses 41. The connection strength between the connecting bolt and the protective cover 2 is improved through the bosses 41 to ensure the stable installation of the microswitch 16.

[0057] Specifically, as an alternative implementation in this embodiment, as Figures 3 to 6 shown, an assembly opening is provided on the top plate 22, an assembly plate 4 is placed on the assembly opening, and the connection holes 42 are opened on the assembly plate 4;

[0058] The lower half of the cylinder column 3 is located on the top plate 22, the upper half of the cylinder column 3 is located on the assembly plate 4, and the connecting column 12 passes through the column holes 31 on the top plate 22 and the assembly plate 4.

[0059] In this embodiment, the assembly plate 4 is mainly to facilitate the installation of the microswitch 16 on the protective cover 2. In the above embodiment, since the protective cover 2 is a whole piece, if the protective cover 2 is installed on the frame in advance, there will not be enough space to install the microswitch 16. Therefore, now an assembly opening and an assembly plate 4 are separately designed on the protective cover 2. After the protective cover 2 is installed on the frame, the microswitch 16 can be assembled through the assembly plate 4. After the microswitch 16 is installed on the assembly plate 4, the assembly plate 4 is then set in the assembly opening of the protective cover 2 to facilitate the assembly of the microswitch 16.

[0060] Specifically, as an alternative implementation in this embodiment, as Figure 6 and Figure 7 shown, the number of the cylinder columns 3 is three, namely the first cylinder column 301, the second cylinder column 302 and the third cylinder column 303;

[0061] The connecting column 12 passes through the first cylinder column 301 and the second cylinder column 302 respectively;

[0062] A bottom bolt 13 is provided on the lower mounting plate 10, and the lower end of the third cylinder column 303 is sleeved on the bottom bolt 13.

[0063] As Figures 4 to 6As shown, the first cylindrical column 301 and the second cylindrical column 302 are divided into upper and lower parts. The lower part is located on the front plate 21, and the upper part is located on the mounting plate 4. When the mounting plate 4 is assembled with the protective cover 2, the upper and lower cylindrical columns are exactly matched with each other.

[0064] The protective cover 2 can be installed on the frame through the first cylindrical column 301 and the second cylindrical column 302. However, when the size of the protective cover 2 is relatively long, in order to improve the stability of the edge position of the protective cover 2, a third cylindrical column 303 is added. The third cylindrical column 303 is sleeved with a bottom bolt 13 on the lower mounting plate 10, and the protective cover 2 is limited through the bottom bolt 13, thereby improving the stability of the protective cover 2 on the frame.

[0065] In the electric operating mechanism of the present utility model, the internal gear mechanism 14 can be shielded by the protective cover 22 installed on the side of the frame, preventing the internal gears from causing danger to the outside and improving the operating safety of the electric operating mechanism.

[0066] In order to facilitate the storage and arrangement of the wires in the electric operating mechanism, in this embodiment, a plurality of wire harness clamping openings 5 are provided on the inner side of the front plate 21. The wires in the electric operation are clamped in the wire harness clamping openings 5 to avoid the wires being in a mess.

[0067] All the devices (components without specific structures described) selected in this application are common standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or obtained through conventional experimental methods.
