[0029] Please refer to Figures 1 to 8 As shown, this utility model discloses a controller for controlling a drive mechanism.

[0030] See Figure 1 and Figure 2 The controller includes a control box 1, a circuit board 2, a battery pack 3, and a battery compartment 4. The battery compartment 4 is used to house the battery pack 3. The circuit board 2, the battery compartment 4, and the battery pack 3 are all located in the control box 1. The circuit board 2 is a PCB board.

[0031] See Figure 1The control box 1 includes a box body 11 and a cover 12. The cover 12 is connected to the box body 11, and the cover 12 and the box body 11 can be opened and closed. The circuit board 2 is located inside the box body 11. The controller includes a first support frame 5, which is located inside the box body 11. The battery compartment 4 is rotatably connected to the first support frame 5, allowing the battery pack 3 to be opened or closed relative to the circuit board 2. When the controller needs maintenance, the cover 12 of the control box 1 is opened, and the battery compartment 4 is freely flipped open relative to the circuit board 2. The circuit board 2 and corresponding connecting wires inside the control box 1 are exposed, providing sufficient operating space for maintenance and avoiding the problem of needing to remove the battery pack 3 before operation, thus simplifying the process. In addition, the flipping and opening of the battery compartment 4 relative to the circuit board 2 also facilitates the replacement of the battery pack 3, improving maintenance efficiency.

[0032] See Figure 2 and Figure 3 The box body 11 includes a bottom wall portion 111 and a peripheral wall portion. The peripheral wall portion includes a first side wall portion 112 and a second side wall portion 113 opposite to the first side wall portion 112.

Specifically, the cover 12 is rotatably connected to the first side wall portion 112 of the box body 11 via a hinge, and the cover 12 is connected to the second side wall portion 113 of the box body 11 via a snap-fit, eliminating the cumbersome operation of screw tightening.

[0033] For details, see Figure 3 The hinge includes a third sleeve 131, a fourth sleeve 132, and a shaft. The third sleeve 131 is connected to the first side wall portion 112 of the housing 11, and the fourth sleeve 132 is connected to the cover 12. The shaft passes through the third sleeve 131 and the fourth sleeve 132. The first support frame 5 is close to the first side wall portion 112 relative to the second side wall portion 113, so that the battery compartment 4 and the cover 12 open in the same direction.

[0034] See Figure 1 The battery compartment 4 is connected to the first support frame 5 by a hinge 6. When the battery pack 3 is closed relative to the circuit board 2, the battery compartment 4 is opposite to the circuit board 2, and there is a gap between the battery compartment 4 and the circuit board 2. This is beneficial for the heat dissipation of the battery pack 3.

[0035] For details, see Figure 4 and Figure 5 The hinge 6 includes a fixed member 61, a movable member 62, and a rotating shaft. The fixed member 61 includes a first sleeve 611 and a first plate 612 connected to the first sleeve 611. The movable member 62 includes a second sleeve 621 and a second plate 622 connected to the second sleeve 621. The rotating shaft passes through the first sleeve 611 and the second sleeve 621. The first plate 612 is bolted to the first support frame 5, and the second plate 622 is bolted to the battery compartment 4. The second sleeve 621 rotates relative to the first sleeve 611 around the rotating shaft.

[0036] See Figure 2 and Figure 3 The battery compartment 4 includes a first bracket 41 and a second bracket 42 connected to the first bracket 41. The battery pack 3 is installed in the space enclosed by the first bracket 41 and the second bracket 42. The second bracket 42 faces away from the circuit board 2 relative to the first bracket 41. The first bracket 41 includes a first bracket body and two first connecting ears 413 connected to both sides of the first bracket body. The first bracket body is used to cover one side of the battery pack 3. Two first support frames 5 are provided, and each first connecting ear 413 is connected to the corresponding first support frame 5 by a hinge 6. The second bracket 42 includes a second bracket body and two second connecting ears 423 connected to both sides of the second bracket body. The second bracket body is used to cover the other side of the battery pack 3. The two second connecting ears 423 are respectively fixedly connected to the two first connecting ears 413 by bolts.

[0037] For details, see Figure 2 and Figure 3 The first bracket body includes a first plate portion 411 and first bent portions 412 that bend vertically from the periphery of the first plate portion 411. The battery pack 3 includes a first surface 31, a second surface 32, and an outer peripheral surface 33. The first plate portion 411 contacts the first surface 31, and the first bent portions 412 contact a portion of the outer peripheral surface 33. The second bracket body includes a second plate portion 421 and second bent portions 422 that bend vertically from the periphery of the second plate portion 421. The second plate portion 421 contacts the second surface 32, and the second bent portions 422 contact another portion of the outer peripheral surface 33. Both the first plate portion 411 and the second plate portion 421 have a cross-shaped structure. The first bracket 41 has four first bent portions 412, and the second bracket 42 has four second bent portions 422. The four first bent portions 412 and the four second bent portions 422 together encircle the outer peripheral surface 33 of the battery pack 3. Two first connecting ears 413 are perpendicularly connected to two of the first bends 412 respectively, and two second connecting ears 423 are perpendicularly connected to two of the second bends 422 respectively.

[0038] See Figure 6 The controller includes a buffer layer 7. In some embodiments, the buffer layer 7 is located on the side of the second bracket body facing away from the first bracket 41. When the cover 12 of the control box 1 is fastened, the entire battery compartment 4 is tightly attached to the inside of the cover 12 through the buffer layer 7. When the controller rotates with the main beam 10, the battery compartment 4 and the battery pack 3 will not shake or sway. Of course, in other embodiments, the buffer layer 7 can also be located on the side of the second bracket body facing the first bracket 41, that is, the buffer layer 7 is located between the second bracket body and the battery pack 3, thus protecting the battery pack 3.

[0039] See Figure 8The controller includes a base plate 81, an upper support column 82, and a lower support column 83. The lower support column 83 is connected to the bottom wall 111 of the housing 11, the base plate 81 is connected to the lower support column 83, the upper support column 82 is connected to the side of the base plate 81 facing away from the bottom wall 111, the circuit board 2 is connected to the upper support column 82, and the first support frame 5 is connected to the base plate 81. That is to say, there is a gap between the base plate 81 and the bottom wall 111 of the housing 11, and there is also a gap between the circuit board 2 and the base plate 81, which is conducive to heat dissipation of the circuit board 2.

[0040] See Figure 7 and Figure 8 The controller includes two second support frames 9 connected to the base plate 81. The two second support frames 9 and two first support frames 5 are respectively arranged at the four corners of the base plate 81. The second support frames 9 are opposite to the first support frames 5. The second support frames 9 are used to support the first connecting ear 413 of the first bracket 41. The second support frames 9 support the end of the battery compartment 4 away from the hinge 6, thereby reducing the pressure on the first support frame 5.

[0041] The first support frame 5 extends at least partially out of the box body 11. When the battery pack 3 is closed relative to the circuit board 2, the battery pack 3 extends at least partially out of the box body 11 and is clamped between the cover 12 and the second support frame 9, thereby improving the stability of the battery pack 3.
