Description

Technical Field

[0001] This invention relates to the field of pistol drill technology, specifically a lithium-ion fast-charging pistol drill. Background Technology

[0002] Electric drills are the best-selling product in the power tool industry, widely used in construction, decoration, furniture and other industries. They are used to drill holes or pierce objects. Due to their convenient function, electric drills have become a household tool as ubiquitous as screwdrivers. Currently, electric drills on the market are divided into two types according to their power supply method: one is corded, which requires an extension cord and has a limited range of use, making it unsuitable for home use; the other is battery powered, which has no restrictions on its range of use and is more common.

[0003] Patent application CN201821724576.2 discloses a charging structure for a lithium battery in a handgun drill, including a drill body, a drill bit, a handle, and a switch. The drill bit is mounted on the side of the drill body, the handle is fixedly connected to the bottom of the drill body, the switch is fixedly connected to the side of the handle, and a storage cylinder is fixedly connected to the bottom of the handle. By setting a limiting rod, removing the limiting rod and pulling the charging plug causes the charging cable to extend out of the storage cylinder, changing the charging cable from a bent and folded state to a straight state. The folding rod is pushed along the sliding through hole by the charging cable. When the charging cable needs to be stored after charging, the folding rod is pressed into the storage cylinder from top to bottom along the surface of the storage cylinder. The folding rod bends and folds the charging cable through the folding through hole, storing the charging cable in the storage cylinder. Finally, the limiting rod is inserted into the limiting through hole to restrict the position of the folding rod, achieving the effect of convenient charging.

[0004] While existing equipment can power a pistol drill via battery, in some cases the backup battery may also run out, forcing a temporary interruption of operations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a lithium-ion battery fast-charging pistol drill to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lithium battery fast-charging pistol drill, comprising a drill body, a handle fixedly connected to the bottom of the drill body, a battery fixedly connected to the bottom of the handle, a cavity opened in the inner wall of the handle, a wrench movably connected to the inner side of the top of the handle, and a switching mechanism fixedly connected to the inner wall of the cavity.

[0007] The switching mechanism includes:

[0008] A central power board has a second connecting plate fixedly connected to its front end, the inner side of which is fixedly connected to a cavity. A third connecting plate is fixedly connected to the top of the central power board, the inner side of which is fixedly connected to the cavity. A first limiting plate is fixedly connected to the bottom of the central power board, a power supply component is movably connected to the inner wall of the first limiting plate, and a first interface is fixedly connected to the inner side of the first limiting plate. A second limiting plate is fixedly connected to the rear side of the central power board, and a charging component is movably connected to the inner wall of the second limiting plate. A second interface is fixedly connected to the inner side of the board, where the power supply component and charging component can be moved to change the state of the device. With the switching mechanism and exposed charging port, when the user faces a situation where the backup battery is also out of power, an external power cord can be connected. At this time, the device can be directly powered by an external power source, thus continuing to work and avoiding work interruption due to battery depletion. At the same time, this design allows the device to automatically switch to charging the built-in battery when it is connected to a power source and in a standby state, improving the efficiency of the tool and enhancing its battery life.

[0009] According to the above technical solution, the power supply component includes a first power-conducting plate, the outer wall of the first power-conducting plate is movably connected to a first limiting plate, a connecting ring is fixedly connected to the outer wall of the first power-conducting plate, a first elastic component is fixedly connected to the inner wall of the connecting ring, and the top of the first elastic component is fixedly connected to the central power-conducting plate. The first elastic component can assist the power supply component in resetting.

[0010] According to the above technical solution, limit rods are fixedly connected to both the left and right sides of the connecting ring, and first movable plates are rotatably connected to both the left and right sides of the connecting ring via bearings. Limit grooves are formed on the outer walls of the two first movable plates, and the inner walls of the limit grooves are movably connected to the limit rods. Sliding plates are fixedly connected to the outer walls of the two first movable plates. The limit rods are used to limit the maximum deflection angle of the first movable plates.

[0011] According to the above technical solution, a hollow column is fixedly connected to the top of the second limiting plate, a slot is opened on the outer side of the second limiting plate, a round hole is opened on the outer side of the bottom of the second limiting plate, and a locking component is movably connected to the inner wall of the hollow column, wherein the locking component can lock the position of the charging component.

[0012] According to the above technical solution, a second sliding groove is provided on the outer side of the central power board, a second elastic component is fixedly connected to the inner wall of the second sliding groove, and a pressure component is fixedly connected to the top of the second elastic component. The second elastic component is used to assist the pressure component in resetting.

[0013] According to the above technical solution, the charging component includes a second power-conducting plate, the outer wall of which is movably connected to a second limiting plate, a second connecting rod fixedly connected to the outer side of the second power-conducting plate, a second slider fixedly connected to the end of the second connecting rod away from the second power-conducting plate, the outer wall of the second slider being movably connected to a sliding groove plate, and a third elastic component fixedly connected to the bottom of the second power-conducting plate, the end of the third elastic component away from the second power-conducting plate being fixedly connected to a circular hole. The movement of the charging component can change the deflection angle of the first movable plate via the second slider. By setting the charging component, the switching of the entire power supply mode is triggered entirely by the insertion of an external power supply cable. When the power cable is inserted into the charging port, the mechanical movement of the charging component automatically drives the switching mechanism to switch the circuit from a pure battery power supply mode to an external power supply mode. Users do not need to perform any additional switch or button operations, improving the convenience of operation.

[0014] According to the above technical solution, a second movable plate is fixedly connected to the rear side of the second power board. A charging port is opened at the end of the second movable plate away from the second power board. The second movable plate passes through the first elastic component and extends to the outside of the grip. An embedded plate is fixedly connected to the end of the second movable plate away from the charging port. The outer wall of the embedded plate is movably connected to the slot. When the embedded plate is fully embedded in the slot, the position of the charging component can be locked by the locking component.

[0015] According to the above technical solution, the locking assembly includes a first connecting rod, a side plate fixedly connected to the inner wall of the handle, a first sliding groove formed on the outer wall of the side plate, first sliders fixedly connected to both sides of the first connecting rod, the outer wall of the first sliders movably connected to the first sliding groove, a connecting block fixedly connected to the outer wall of the first connecting rod, a circular plate fixedly connected to the bottom of the connecting block, the outer wall of the circular plate movably connected to a hollow column, a force-bearing rod fixedly connected to the side of the circular plate away from the connecting block, the force-bearing rod penetrating the hollow column and extending to the inner wall of the groove, a spring sleeved on the outer wall of the force-bearing rod, one end of the spring fixedly connected to the circular plate, and the end of the spring away from the circular plate fixedly connected to the hollow column. The bottom of the force-bearing rod has a certain inclination angle to facilitate the insertion of the embedded plate. By setting the locking assembly, when the power cord is inserted and in place, the locking assembly can automatically lock the position of the charging assembly under the action of the spring, preventing loosening or power failure due to vibration or accidental pulling during operation, thus ensuring the reliability of long-term, high-intensity operation.

[0016] According to the above technical solution, the pressure assembly includes a first connecting plate, the inner wall of the second slide groove is movably connected to the first connecting plate, the bottom of the first connecting plate is fixedly connected to the second elastic component, pressure plates are fixedly connected to both sides of the first connecting plate, and a sliding rod is fixedly connected to the top of the pressure plate. The sliding rod slides through the cavity and extends to the rear side of the wrench. The top of the sliding rod is rotatably connected to a handle through a bearing. The movement of the wrench can apply pressure to the top of the force roller, thereby driving the pressure assembly to move downward. By setting the pressure assembly, when the user pulls the wrench to perform drilling operations, the pressure assembly will drive the power supply component to change position. This process physically cuts off the charging circuit, so that when the power output is high, all the energy of the external power supply is used to drive the motor, instead of charging the battery at the same time, effectively ensuring that the motor can obtain a full and stable power supply.

[0017] Compared with the prior art, the present invention provides a lithium battery fast-charging pistol drill, which has the following beneficial effects:

[0018] 1. By setting up a switching mechanism and an exposed charging port, this invention allows users to connect an external power cord when the backup battery is also out of power. In this case, the device can be directly powered by an external power source to continue working, avoiding work interruption due to battery depletion. At the same time, this design enables the device to automatically switch to charging the built-in battery when connected to a power source and in a standby state, improving the efficiency of the tool and enhancing battery life.

[0019] 2. By setting up a pressure component, when the user pulls the wrench to perform drilling operations, the pressure component will drive the power supply component to change position. This process physically cuts off the charging circuit, so that when the power output is high, all the energy of the external power supply is used to drive the motor, instead of charging the battery at the same time, effectively ensuring that the motor can obtain a full and stable power supply.

[0020] 3. By setting up a charging component, the entire power supply mode switching is triggered by the action of inserting an external power supply cable. When the power cable is inserted into the charging port, the mechanical movement of the charging component will automatically drive the switching mechanism to switch the circuit from pure battery power supply mode to external power supply mode. Users do not need to perform any additional switch or button operations, which improves the convenience of operation.

[0021] 4. By setting a locking component, the present invention can automatically lock the position of the charging component under the action of the spring after the power cord is inserted and in place, preventing loosening or power failure due to vibration or accidental pulling during operation, thus ensuring the reliability of long-term, high-intensity operation.

[0033] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Example 1: See Figures 1-5 The present invention provides a technical solution: a lithium battery fast-charging pistol drill, including a drill body 1, a handle 102 fixedly connected to the bottom of the drill body 1, a battery 103 fixedly connected to the bottom of the handle 102, a cavity 106 opened in the inner wall of the handle 102, a wrench 101 movably connected to the inner side of the top of the handle 102, and a switching mechanism 2 fixedly connected to the inner wall of the cavity 106.

[0036] The switching mechanism 2 includes: a central power supply plate 201, a second connecting plate 202 fixedly connected to the front end of the central power supply plate 201, the inner side of the second connecting plate 202 fixedly connected to the cavity 106, a third connecting plate 203 fixedly connected to the top of the central power supply plate 201, the inner side of the third connecting plate 203 fixedly connected to the cavity 106, a first limiting plate 204 fixedly connected to the bottom of the central power supply plate 201, a power supply component 21 movably connected to the inner wall of the first limiting plate 204, a first interface 205 fixedly connected to the inner side of the first limiting plate 204, a second limiting plate 207 fixedly connected to the rear side of the central power supply plate 201, a charging component 23 movably connected to the inner wall of the second limiting plate 207, and a charging component 23 fixedly connected to the inner side of the second limiting plate 207. A second interface 209 is provided, in which the positions of the power supply component 21 and the charging component 23 can be moved to change the state of the device. A hollow column 2010 is fixedly connected to the top of the second limiting plate 207. A slot 2011 is opened on the outer side of the second limiting plate 207, and a round hole 208 is opened on the outer side of the bottom of the second limiting plate 207. A locking component 22 is movably connected to the inner wall of the hollow column 2010, wherein the locking component 22 can lock the position of the charging component 23. A second sliding groove 2012 is opened on the outer side of the central power plate 201. A second elastic component 2013 is fixedly connected to the inner wall of the second sliding groove 2012. A pressure component 11 is fixedly connected to the top of the second elastic component 2013, wherein the second elastic component 2013 is used for... The auxiliary pressure component 11 is reset; when no external power cord is inserted, the switching mechanism 2 is in the initial position; in the power supply component 21, the elastic force of the first elastic component 206 keeps the first energized plate 211 in contact with the first interface 205 on the central energized plate 201, thereby connecting the circuit of the battery 103 and providing power to the motor of the drill body 1; when the operator inserts the external power cord into the charging port 237, the charging component 23 is pushed inward, causing the second energized plate 231 to contact the second interface 209, thereby connecting the external power to the circuit of the central energized plate 201; at the same time, this movement will change the deflection state of the first movable plate 214, so that the power supply component 21 enters a position that can be driven by the pressure component 11; if the operator does not... When the wrench 101 is pulled, the pressure component 11 is not triggered; the current from the external power supply mainly flows to the already connected charging circuit to charge the battery 103; while the path to the motor drive circuit is in a high-resistance state and the current is extremely small because the wrench is not pressed down; when the wrench 101 is pulled to start the electric drill, the rear part of the wrench presses down the force roller 112, which drives the sliding rod 111 and the pressure plate 113 to move downward, thereby driving the power supply component 21 to move downward, so that the power supply component 21 is separated from the first interface 205, thereby physically cutting off the charging circuit. At this time, all the electrical energy from the external power supply is supplied to the motor of the drill body 1 to ensure that it receives full power; when the wrench 101 is released, the pressure component 11 rises under the reset action of the second elastic component 2013, relieving the pressure on the power supply component 21;The charging circuit resets under the elastic action of the third elastic component 232, and the external power supply automatically charges the battery 103 again.

[0037] The pressure assembly 11 includes a first connecting plate 114, the inner wall of the second slide groove 2012 is movably connected to the first connecting plate 114, the bottom of the first connecting plate 114 is fixedly connected to the second elastic assembly 2013, pressure plates 113 are fixedly connected to both sides of the first connecting plate 114, and a sliding rod 111 is fixedly connected to the top of the pressure plate 113. The sliding rod 111 slides through the cavity 106 and extends to the rear side of the wrench 101. The top of the sliding rod 111 is rotatably connected to the handle 102 through a bearing. The movement of the wrench 101 can apply pressure to the top of the force roller 112, thereby driving the pressure assembly 11 to move downward.

[0038] Example 2: Please refer to Figures 5-8 Based on Embodiment 1, the present invention provides a technical solution: the power supply component 21 includes a first energized plate 211, the outer wall of the first energized plate 211 is movably connected to a first limiting plate 204, a connecting ring 212 is fixedly connected to the outer wall of the first energized plate 211, a first elastic component 206 is fixedly connected to the inner wall of the connecting ring 212, and the top of the first elastic component 206 is fixedly connected to the central energized plate 201. The first elastic component 206 can assist the power supply component 21 in resetting. Limiting rods 213 are fixedly connected to both sides of the connecting ring 212, and first movable plates 214 are rotatably connected to both sides of the connecting ring 212 via bearings. Limiting grooves 215 are formed on the outer walls of both first movable plates 214, and the inner walls of the limiting grooves 215 are movably connected to the limiting rods 213. Both first movable plates 214 have a sliding groove plate 216 fixedly connected to their outer walls. The limiting rod 213 is used to limit the maximum deflection angle of the first movable plate 214. When the charging component 23 is pushed inward by the power plug, the second slider 235 moves accordingly. Since the slider is embedded in the sliding groove plate 216 of the first movable plate 214, the linear movement of the second slider 235 is converted into a thrust on the sliding groove plate 216, causing the two first movable plates 214 to deflect upward around the bearing connected to the connecting ring 212. When the user pulls the wrench 101, the first connecting plate 114 of the pressure component 11 is pressed down, and the pressure plates 113 on both sides of it press directly down on the first movable plate 214. This downward pressure causes the first energized plate 211 to separate from the first interface 205, cutting off the battery discharge or charging circuit.

[0039] The charging assembly 23 includes a second energized plate 231. The outer wall of the second energized plate 231 is movably connected to the second limiting plate 207. A second connecting rod 234 is fixedly connected to the outer side of the second energized plate 231. A second slider 235 is fixedly connected to the end of the second connecting rod 234 away from the second energized plate 231. The outer wall of the second slider 235 is movably connected to the slide plate 216. A third elastic component 232 is fixedly connected to the bottom of the second energized plate 231. The end of the third elastic component 232 away from the second energized plate 231 is fixedly connected to the circular hole 208. The movement of the charging assembly 23 can be achieved through the second slider. 235 Change the deflection angle of the first movable plate 214. The second movable plate 236 is fixedly connected to the rear side of the second power plate 231. A charging port 237 is opened at the end of the second movable plate 236 away from the second power plate 231. The second movable plate 236 passes through the first elastic component 206 and extends to the outside of the grip 102. An embedded plate 233 is fixedly connected to the end of the second movable plate 236 away from the charging port 237. The outer wall of the embedded plate 233 is movably connected to the slot 2011. When the embedded plate 233 is fully embedded in the slot 2011, the position of the charging component 23 can be locked by the locking component 22.

[0040] The locking assembly 22 includes a first connecting rod 222. A side plate 104 is fixedly connected to the inner wall of the handle 102. A first groove 105 is formed on the outer wall of the side plate 104. First sliders 221 are fixedly connected to both sides of the first connecting rod 222. The outer wall of the first sliders 221 is movably connected to the first groove 105. A connecting block 223 is fixedly connected to the outer wall of the first connecting rod 222. A circular plate 224 is fixedly connected to the bottom of the connecting block 223. The outer wall of the circular plate 224 is movably connected to the hollow column 2010. A force-bearing rod 225 is fixedly connected to the side of the circular plate 224 away from the connecting block 223. The force-bearing rod 225 passes through the hollow column 2010 and extends to the inner wall of the groove 2011. A spring 226 is sleeved on the outer wall of the force-bearing rod 225. One end of the spring 226 is fixedly connected to the circular plate 224. The end of spring 226 away from circular plate 224 is fixedly connected to hollow column 2010. The bottom of force rod 225 has a certain inclination angle to facilitate the insertion of embedded plate 233. When charging component 23 moves to the innermost end due to the insertion of power cord, embedded plate 233 will slide in along slot 2011. During the sliding process, the inclined surface at the front end of embedded plate 233 contacts and compresses the inclined surface at the bottom of force rod 225 in locking component 22. This compression makes way for embedded plate 233. When embedded plate 233 has completely slid past the front end of force rod 225, the compressed spring 226 immediately releases its elastic force, pushing circular plate 224 and force rod 225 to rebound, so that the end of force rod 225 enters the slot of embedded plate 233, thereby locking charging component 23 in this position and preventing it from retracting due to vibration.
