It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present utility model.

[0023] As Figures 1 to 5 shown, the present utility model provides a hanging electric winch, which includes an electric motor, a bracket, a winch drum and a planetary gear reducer. The electric motor and the planetary gear reducer are respectively installed on both sides of the bracket. The winch drum is rotatably connected between the brackets. The electric motor and the planetary gear reducer are connected via a transmission shaft. The transmission shaft passes through the winch drum to reach the input sun gear of the planetary gear reducer for transmission connection. It further includes a connection seat connected to the upper side of the bracket. The connection seat includes a bottom plate, a triangular left side plate and a triangular right side plate. The left side plate is vertically arranged at the left end of the bottom plate, and the bottom edge of the left side plate is connected to or integrally formed with the left end of the bottom plate. The right side plate is vertically arranged at the right end of the bottom plate, and the bottom edge of the right side plate is connected to or integrally formed with the right end of the bottom plate. A cross bar is connected between the top ends of the left side plate and the right side plate. The cross bar is rotatably connected to a hook for hanging.

[0024] In some embodiments, as Figure 1As shown in the figure, the hook includes a left vertical rod on one side of the left side plate and a right vertical rod on one side of the right side plate. The lower end of the left vertical rod is wound around the cross bar to form a left rotation fitting hole, and the lower end of the right vertical rod is wound around the cross bar to form a right rotation fitting hole. The left vertical rod extends upward and is arc-shaped to form a left bent part for hanging, and the right vertical rod extends upward and is arc-shaped to form a right bent part for hanging. A reinforcing rod is also connected between the end of the left bent part and the end of the right bent part. In this way, the hanging force is better, and at the same time, the hanging opening is large, so it is convenient for hanging.

[0025] In this example, as Figure 1 shown, the hook is made by bending a metal rod.

[0026] In some embodiments, as Figure 1 、 2 shown, both the left side plate and the right side plate are isosceles triangles.

[0027] In some embodiments, as Figure 1 、 3 shown, the bracket includes a left L-shaped support plate and a right L-shaped support plate. The horizontal part of the left L-shaped support plate is bolted up and down to the left side of the bottom plate, and the horizontal part of the right L-shaped support plate is bolted up and down to the right side of the bottom plate. In this way, the bearing capacity is strong, and at the same time, it is convenient for production and manufacturing. In addition, the bottom plate can also act as a connecting rod to strengthen the bracket.

[0028] In some embodiments, as Figure 1 、 3 shown, reinforcing strips are provided on both the front and back sides of the bottom plate. The two ends of the front reinforcing strip are respectively connected to the front end of the bottom edge of the left side plate and the front end of the bottom edge of the right side plate, and the two ends of the rear reinforcing strip are respectively connected to the rear end of the bottom edge of the left side plate and the rear end of the bottom edge of the right side plate. In this way, the bottom plate has higher strength and does not interfere with the hanging at the same time.

[0029] Furthermore, the reinforcing strip can be obtained by bending the front and back sides of the bottom plate, that is, integrally provided.

[0030] In some embodiments, as Figure 1 、 3 、Figure 4 shown, the bracket includes a left support plate and a right support plate. The outside of the right support plate is connected to the electric motor. Two connection holes are provided on the right support plate along the up and down direction. The distance between the two connection holes is less than the diameter of the right side part of the winch drum. The connection bolt passes through from the inner side of the right support plate and enters the electric motor. This connection bolt is used to connect the electric motor, and the head of the connection bolt sinks into the right support plate and is blocked by the right support plate. In this way, the connection bolt is hidden, and there is no need to open an exposed through hole at the right end of the electric motor.

[0031] In this example, as Figure 1 、 3As shown, the left support plate and the right support plate are respectively arranged as the left L-shaped support plate and the right L-shaped support plate.

[0032] In this example, as Figure 1 shown, the hoisting drum further includes a left side portion, and the portion between the left side portion and the right side portion is the drum.

[0033] Furthermore, as Figure 3 、 5 shown, the connecting bolts are inserted between the stator of the electric motor and the housing, and axial avoidance grooves are provided between adjacent stators, and the connecting bolts are matched with the axial avoidance grooves. In this way, the radial dimension of the electric motor is smaller.

[0034] Furthermore, as Figure 5 shown, the axial avoidance grooves are also used for circumferentially limiting the stator.

[0035] When understanding the present utility model, if necessary, the above structures can refer to other embodiments / attachments Figure 1 and be understood, and will not be elaborated here.

[0036] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, thinking of changes or substitutions, should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
