Description

Technical Field

[0001] The present invention relates to the field of cordless tools, and particularly to handheld tools.

Background Art

[0002] With the development of the battery industry, lithium battery packs are widely used in other fields such as power tools, gardening tools, cleaning electrical appliances, E-Bike / balance cars / kick scooters, UPS / portable energy storage power supplies, etc. Conventional battery packs, especially the in-line lithium battery packs used in cordless handheld tools, mostly use a sealed cap with a locking structure. The sealed cap is provided with a deadbolt that cooperates with the tool housing. At the same time, the sealed cap is further provided with a surface that can be pressed by fingers to control the detachment and connection of the battery pack and the power tool by the pressure of the operator's fingers of the power tool. For example, Chinese Patent Publication No. CN203746928U discloses "a battery pack including a battery core, connection terminals, an inner case, a sleeve for the case, and a lock clip. The battery core is installed in the inner case. One end of the sleeve for the case is open and the other end is sealed. It is fixed to one end of the inner case. A part of the inner case is installed in the sleeve for the case. At the other end of the inner case, a terminal interface for connecting the connection terminals to the outside is installed. An insertion structure is provided at the part of the inner case exposed from the sleeve for the case. The sleeve for the case is provided with an operation wall for unlocking the lock clip and locking the lock clip in a free state when operating." However, many such battery packs can only be compatible with specific model numbers of tools.

The power system 4 is provided in the housing cavity, and the power system 4 includes a drive unit and a transmission mechanism.

[0048] After the battery pack is inserted into the cavity of the battery storage chamber 30 of the tool, the lower end surface of the battery pack does not extend beyond the exit end surface of the battery storage chamber 30. Preferably, after the battery pack is inserted into the cavity of the battery storage chamber 30, the lower end surface of the battery pack is on the same plane as the exit end surface of the battery storage chamber 30, and the lower end surface of the battery end forms part of the lower bottom surface of the tool gripping portion 20.

[0049] A circuit board is further provided in the housing cavity of the tool housing 2, and the circuit board is electrically connected to the battery pack and the power system 4, and is used to control the discharge of the battery pack and the operation of the power system 4.

[0050] The tool housing 2 includes a gripping portion 20, and a battery storage chamber 30 within the gripping portion 20 communicates with a housing cavity. In this embodiment, the battery storage chamber 30 is part of the housing cavity, and the tool housing 2 is formed by joining two housing elements.

[0051] The locking mechanism is installed at a location close to the exit of the battery storage chamber 30 at the lower end of the tool gripping portion 20, and the locking mechanism is movably connected to a positioning hole 118 on the battery pack to lock or unlock the battery pack. In this embodiment, there are various embodiments of the locking mechanism, and specifically, as shown in Figures 6 to 12, the locking structure 31 includes a deadbolt 311, a button 310 and a spring 312, the deadbolt 311 has an operating state in which it extends to prevent the battery pack from detaching from the exit of the battery storage chamber 30, and the spring 312 is connected to the deadbolt 311 and drives the deadbolt 311 to extend and retract. When the button 310 is pressed, the deadbolt 311 retracts and unlocks the battery pack. At this time, the battery pack pops out of the battery compartment 30 under the action of the pop-out mechanism 32. After inserting the batteries, the deadbolt 311 is automatically reset under the action of the spring 312, and the deadbolt 311 is inserted into the positioning hole 118 on the battery pack, locking the battery pack inside the battery compartment 30.

When the battery pack is inserted into the battery storage chamber 30, the sliding member 321 moves upward, compressing the spring 312. When the locking mechanism is unlocked, the spring 312 resets the sliding member 321, causing the battery pack to eject from the battery storage chamber 30.

[0054] The open end of the battery storage chamber 30 allows insertion of only one end of the battery pack that does not have a foolproof structure. After the battery pack is inserted, the first output interface of the battery pack is connected to the electrical interface of the tool to supply power to the tool.

[0055] Example 3: As shown in Figures 10 to 13, an embodiment of the present invention provides a handheld tool for ejecting a battery pack by pressing, which allows the battery pack to be removed from the battery storage chamber 30 by pressing one end of the battery.

The battery storage chamber 30 is made up of a cylindrical housing with both ends open, one end of the battery storage chamber 30 is fixedly connected to the tool housing 2, and the other end of the battery storage chamber 30 is used for inserting and removing the battery. The ejection mechanism 32 is a push-type ejection mechanism, and is attached to one end facing the exit of the battery storage chamber 30. The locking mechanism restricts the position of the battery provided in the battery storage chamber 30 so as to prevent the battery from detaching from the exit of the battery storage chamber 30, and the battery is installed in the battery storage chamber 30 so as to be insertable and removable.

[0057] After the battery pack is inserted into the battery compartment 30, the lower end surface of the battery is substantially in the same plane as the lower end surface of the battery compartment 30.

[0058] The locking structure 31 is installed at one end facing the exit of the battery storage chamber 30. The locking structure 31 includes a sleeve 313, a sliding base 314, and a deadbolt 311 installed on the sliding base 314. The sleeve 313 has a notch. When the deadbolt 311 on the sliding base 314 slides into the notch, the deadbolt 311 separates from the positioning hole 118 on the battery pack, allowing the battery pack to be removed from the battery storage chamber 30. When the deadbolt 311 separates from the notch, it is pushed out by the sleeve 313 and then fitted into the positioning hole 118 on the battery pack, fixing the battery pack inside the battery storage chamber 30.

[0059] The pop-out mechanism 32 includes a fixed block 323 installed on a sliding base 314, the fixed block 323 being fixedly connected to the upper end of a sleeve 313, the side of which has a chamfered heart-shaped stopper block 3230, and the pop-out mechanism 32 further includes a moving member 324 that penetrates from the sliding base 314 and cooperates with the stopper block 3230 on the fixed block 323, one end of the moving member 324 being in contact with the battery pack, and the other end of the moving member 324 cooperating with the stopper block 3230. The pop-out mechanism 32 further includes an elastic member 322 installed inside the fixed block 323 that pushes the sliding base 314 and slides it up and down, the elastic member 322 driving the sliding base 314 up and down, thereby controlling the engagement between the deadbolt 311 and the positioning hole 118 on the battery pack to lock or unlock the battery. The fixed block 323 and the sliding base 314 are provided with a connecting structure that allows them to cooperate with each other, so that the fixed block 323 can move only within a predetermined stroke relative to the sliding base 314.

[0060] The fixed block 323 is further provided with tool terminals, which are connected to the first output interface of the battery pack to supply power to the tool.

[0061] A slide rail is installed around the stopper block 3230, and when the battery pack is pressed, the moving member 324 slides in one direction within the slide rail.

[0062] In the present invention's press-and-release mechanism, when the battery pack is inserted into the battery storage chamber 30, the moving member 324 is positioned in the recess of the stopper block 3230, at which point the elastic member 322 is compressed, and the deadbolt 311 is fitted into the positioning hole 118 on the battery pack, locking the battery in place. When the battery pack is pressed again, the moving member 324 moves downward along the slide rail, at which point the elastic member 322 is released, driving the battery pack and sliding base 314 downward, and the deadbolt 311 slides down. When the deadbolt 311 moves to the notch on the 313, it separates from the positioning hole 118 of the battery pack, and at this time the battery pack is removed from the battery storage chamber 30. When the battery is reinstalled, the battery pushes the moving member 324 and the sliding base 314 upward, causing the deadbolt 311 to be pushed out by the sleeve 313 and come into contact with the positioning hole 118 of the battery pack, fixing the battery pack in place. At this time, the moving member 324 is similarly positioned in the recess of the stopper block 3230, and the spring 312 is compressed. This allows the battery to be stored inside the battery storage chamber 30 and to be ejected from the battery storage chamber 30 in a cyclical manner with the press.

[0063] After the battery pack is inserted into the battery storage chamber 30, the lower end surface of the battery pack is substantially in the same plane as the lower end surface of the battery storage chamber 30, and the lower bottom surface of the battery pack constitutes a part of the lower bottom surface of the tool gripping end.

[0064] Example 4: This embodiment provides a battery pack comprising a battery case 11 and a battery core provided in the battery case 11, wherein the surface of the battery case 11 includes a first output interface 114 for supplying power to a tool, a second output interface 115 for supplying power to a mobile device, and an input interface 113 for charging the battery pack 1.

[0065] Furthermore, the surface of the battery case 11 is smooth and has no separate edges.
