Technical Field

[0001] This utility model relates to the field of electric screwdriver technology, specifically a wireless charging electric screwdriver. Background Technology

[0002] An electric screwdriver, also known as an electric screwdriver or electric screwdriver, is an assembly tool powered by electricity, mainly used for tightening and loosening screws, nuts, and other fasteners. It consists of an electric motor, a transmission mechanism, a cutting tool, and a control switch. The electric motor converts electrical energy into mechanical energy, driving the cutting tool to rotate and thus tightening or loosening screws. For ease of use, wireless charging electric screwdrivers are now commonly used. In the prior art, patent publication number CN220783742U discloses a wireless charging electric screwdriver and its base, including a base and a screwdriver. The base has a first circuit board and a transmitting coil disposed inside. The screwdriver has a rear end shell at its tail end. A rechargeable battery is fixedly connected inside the screwdriver. The rear end shell has a second circuit board, a magnetic shielding sheet, and a receiving coil disposed inside. These wireless charging electric screwdrivers have the following disadvantages: when wirelessly charging, the bottom of the electric screwdriver is often placed on the upper surface of the charging base, leaving the screwdriver without support. This makes it prone to tilting and collapsing during charging, causing damage from impacts. To address this, we propose a wireless charging electric screwdriver. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-2This embodiment provides a technical solution: a wireless charging electric screwdriver, including a limiting seat 3, a charging base 1 fixedly connected to the lower surface of the limiting seat 3, a power interface 2 on the outer surface of the charging base 1, a cooling fan 9 fixedly connected to the inner lower surface of the charging base 1, a ventilation opening 7 on the lower surface of the charging base 1, a temperature sensor 8 fixedly connected to the inside of the charging base 1, a processor 10 fixedly connected to the inside of the charging base 1, the input end of the processor 10 electrically connected to the output end of the power interface 2, the input end of the cooling fan 9 electrically connected to the output end of the processor 10, a bidirectional electrical connection between the temperature sensor 8 and the processor 10, an induction coil 11 fixedly connected to the inside of the charging base 1, the input end of the induction coil 11 electrically connected to the output end of the processor 10, a housing 14 inside the limiting seat 3, an induction coil 12 fixedly connected to the inside of the housing 14, and a battery 15 fixedly connected to the inside of the housing 14, the induction coil 12 and the induction coil 11 being configured in cooperation. The input terminal of battery 15 is electrically connected to the output terminal of induction coil 12. Control switch 4 and control switch 5 are fixedly connected to the outer surface of housing 14. The input terminal of control switch 4 is electrically connected to the output terminal of battery 15, and the input terminal of control switch 5 is electrically connected to the output terminal of control switch 4. Motor 16 is fixedly connected inside housing 14. Bit mounting slot 6 is rotatably connected to the upper surface of housing 14. The output shaft of motor 16 is fixedly connected to the lower surface of bit mounting slot 6. The input terminal of motor 16 is electrically connected to the output terminal of control switch 5. When using the wireless charging electric screwdriver, the bit is installed in bit mounting slot 6, control switch 4 is turned on, and the upper end of control switch 5 is pressed. The output shaft of motor 16 rotates, driving bit mounting slot 6 to rotate, and the bit rotates to install the screw. The lower end of control switch 5 is pressed, and the output shaft of motor 16 reverses, driving bit mounting slot 6 to reverse, and the bit reverses to disassemble the screw. It also includes a charging fixing mechanism 13. The charging fixing mechanism 13 includes a slot 131, a limiting block 132, a locking block 133, and a spring 134. The slots 131 are all located on the outer surface of the housing 14. The limiting seat 3 has symmetrically distributed locking blocks 133 slidably connected inside. The outer surfaces of the locking blocks 133 are all fixedly connected to symmetrically distributed limiting blocks 132. A spring 134 is fixedly connected between the end of the locking block 133 away from the housing 14 and the inner wall of the limiting seat 3. Each locking block 133 engages with an adjacent slot 131 on the same side. When charging a wirelessly charging electric screwdriver, the housing 14 is placed downwards inside the limiting seat 3. The spring 134 applies a spring force to the locking blocks 133, causing the locking blocks 133 to move towards the housing 14. The screwdriver is moved and snapped into the adjacent slot 131 on the same side, clamping the outer shell 14. The power interface 2 is connected to the external power source, causing alternating current to be generated inside the first induction coil 11. A magnetic field with constantly changing direction is generated around the first induction coil 11, causing the magnetic flux inside the second induction coil 12 to change continuously, thereby generating an induced electromotive force inside the second induction coil 12. This induces a current inside the second induction coil 12, which enters the battery 15, thus realizing wireless charging. When charging is complete, the outer shell 14 is pulled upward, and the locking block 133 is squeezed by the outer shell 14. The locking block 133 slides away from the outer shell 14, thus completing the removal of the wirelessly charged electric screwdriver.

[0016] The working principle of the wireless charging electric screwdriver provided by this utility model is as follows: When using the wireless charging electric screwdriver, the bit is installed in the bit mounting slot 6. The control switch 1 4 is turned on, and the upper end of the control switch 2 5 is pressed. The output shaft of the motor 16 rotates, driving the bit mounting slot 6 to rotate, thus rotating the bit to install the screw. The lower end of the control switch 2 5 is pressed, causing the output shaft of the motor 16 to reverse, driving the bit mounting slot 6 to reverse, thus rotating the bit to remove the screw. When charging the wireless charging electric screwdriver, the outer shell 14 is placed downwards inside the limiting seat 3. The spring 134 applies elastic force to the locking block 133, causing the locking block 133 to move towards the outer shell 14. The screwdriver moves in the direction and engages with the adjacent slot 131 on the same side, clamping the outer shell 14. The power interface 2 is connected to the external power source, causing alternating current to be generated inside the first induction coil 11. A magnetic field that changes direction continuously is generated around the first induction coil 11, causing the magnetic flux inside the second induction coil 12 to change continuously, thereby generating an induced electromotive force inside the second induction coil 12. This induces a current inside the second induction coil 12, which enters the battery 15, thus realizing wireless charging. When charging is complete, the outer shell 14 is pulled upward, and the locking block 133 is squeezed by the outer shell 14. The locking block 133 slides away from the outer shell 14, thus completing the removal of the wirelessly charged electric screwdriver.

[0017] It is worth noting that in the above embodiments, the temperature sensor 8 is a TK51 temperature sensor, the cooling fan 9 is an FK6621.230, the battery 15 is an MA18-18B, the motor 16 is a C041A motor, and the processor 10 controls the operation of the temperature sensor 8 and the cooling fan 9 using methods commonly used in the prior art. The control switch 2 is provided with a control button corresponding to the motor 16 and used to control its switching.
