DETAILED DESCRIPTION

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1-4 , a battery box with integrated power display on the handle, including a charging and discharging port 3 provided at the upper end of the battery box body 1, which can charge and discharge the battery. The handle includes a handle lower shell 7 and a handle upper shell 8. The handle lower shell 7 is detachably provided at the upper end of the battery box body 1. The upper end of the battery box body 1 below the handle lower shell 7 is set as a concave arc surface 2. The overall shape of the handle lower shell 7 is in the shape of "冖", forming a space for carrying the handle between it and the arc surface 2. The handle upper shell 8 is detachably provided on the handle lower shell 7. Threading ports 6 are provided at both the upper end of the battery box body 1 and the lower end of the handle lower shell 7. When the handle lower shell 7 is fixed to the upper end of the battery box body 1, the two threading ports 6 communicate with each other, facilitating the routing of the wires inside the battery box body 1. A second installation groove 11 for installing the circuit board 13 is provided in the middle of the handle lower shell 7. A plurality of third internal threaded cylinders 12 for positioning the circuit board 13 are fixedly connected to the lower end of the second installation groove 11. A battery switch 14 and a power display lamp 15 are provided on the circuit board 13. This setting method does not involve the improvement of the circuit. A mating hole for the battery switch 14 and the power display lamp 15 to pass through is provided on the handle upper shell 8. Among them, the battery switch 14 passes through the upper end face of the handle upper shell 8, and the power display lamp 15 is located in the mating hole and does not pass through the upper end face of the handle upper shell 8. A pressing cylinder 18 for pressing down the circuit board 13 is fixedly connected to the lower end of the handle upper shell 8, realizing the fixation of the circuit board 13 at the bottom of the first installation groove 4 and preventing the circuit board 13 from moving back and forth. The third internal threaded cylinder 12 is located in the pressing cylinder 18, and the middle of the pressing cylinder 18 penetrates the upper end face of the handle upper shell 8, facilitating the installation of the screw.

[0021] In this embodiment, by displaying the power on the handle, the traditional setting of displaying the power on the battery box body 1 is changed. At the same time, through the cooperative setting between the handle lower shell 7 and the handle upper shell 8, it is possible to separately remove the handle upper shell 8 to repair and replace the circuit board 13, making the overall use more convenient.

[0022] Specifically, in combination with Figure 2-4As shown, a first mounting groove 4 for installing the handle lower shell 7 is opened at the upper end of the battery box body 1, a threading port 6 is opened on the battery box body 1 at the bottom of the first mounting groove 4, and a first internally threaded tube 5 is fixedly connected to the bottom of the first mounting groove 4, and a first through hole 9 for the first internally threaded tube 5 to pass through is provided at the bottom of the handle lower shell 7. When the handle lower shell 7 is installed, the first internally threaded tube 5 will be inserted into the first through hole 9, but will not pass through the upper end of the first through hole 9.

[0023] Specific, combined Figure 2-4 As shown, in order to further facilitate the insertion of the circuit in the handle lower shell 7, a wire threading channel 19 connected to the wire threading port 6 is opened on the inner side of the handle lower shell 7 to prevent the circuit from being squeezed when the handle upper shell 8 is installed.

[0024] Specific, combined Figure 2-4 As shown, a recessed groove 20 is provided at the upper end of the edge of the handle lower shell 7, and a convex strip 21 which is inserted into the recessed groove 20 is fixedly connected to the lower end of the edge of the handle upper shell 8. Through the cooperation between the convex strip 21 and the recessed groove 20, a tight connection between the handle lower shell 7 and the handle upper shell 8 is achieved.

[0025] Installation method: First, insert the handle lower shell 7 into the first installation groove 4. At this time, the threading port 6 will be connected. Pass the line through the threading port 6, stretch it along the threading channel 19 to the second installation groove 11, and connect it with the circuit board. After the connection is completed, pre-install the circuit board 13 on the third internal threaded tube 12, and then thread the screw through the upper end of the first through hole 9 to the inner side of the first internal threaded tube 5. After tightening the screw, the handle lower shell 7 will be fixed in the first installation groove 4. After the installation is completed, install the handle upper shell 8 so that the convex strip 21 is inserted into the recessed groove 20. After the insertion is completed, After completion, the lower end of the pressing cylinder 18 is in contact with the upper end surface of the circuit board 13, and the lower end surface of the circuit board 13 is in contact with the lower end of the second mounting groove 11. At the same time, the third internally threaded cylinder 12 will be inserted into the pressing cylinder 18. After the insertion is completed, the screw is passed through the upper end of the pressing cylinder 18 and threadedly connected to the third internally threaded cylinder 12. After tightening, the handle upper shell 8 will be fixed on the handle lower shell 7. When the circuit board 13 or the electronic components on the circuit board 13 are damaged, you only need to remove the handle upper shell 8 to repair or replace the circuit board 13. There is no need to disassemble the battery box body 1 for repair, which is more convenient.
