[0027] The present disclosure will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present disclosure, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present disclosure.

[0028] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the embodiments of the present disclosure do not represent any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0029] Traditional power tools, such as pruners, chain saws, etc., have a battery pack installed inside to power them. The battery pack is locked in the power tool through an unlocking piece. However, during use, the branches pruned by the pruners are messy and fall off during the pruning process, which can easily cause the unlocking piece of the battery pack to fall off by mistake; or the chain saw may be knocked or scratched by foreign objects during use, and the unlocking piece may be accidentally touched, causing the battery pack to fall off. This application does not limit the type of power tools.

[0030] Taking the chain saw 10 as an example, the chain saw 10 includes: a battery pack, a transmission structure, a housing 100, a saw chain 120, a guide plate, a handle 130, a chain cover and a motor 110. The housing 100 accommodates the motor 110 and the transmission structure, and the battery pack is connected to the housing 100 to power the chain saw 10. Specifically, the motor 110 drives the transmission structure to drive the saw chain 120 to perform the cutting function. The handle 130 is arranged at the end of the housing 100 opposite to the saw chain 120, which is convenient for the operator to hold. Among them, the battery pack is used to provide electrical energy, which can make the working area of ​​the chain saw 10 not restricted by the power cord and more flexible to move. When the chain saw 10 does not need to work, the battery pack can be removed to reduce the weight of the chain saw 10. The chain saw also includes a battery pack unlocking member 160, which controls the removal of the battery pack. The operator applies force to the contact portion 161 in the battery pack unlocking member 160 to change the state of the battery pack unlocking member 160, so that the battery pack unlocking member 160 is converted from a state of locking the battery pack to a state of releasing the battery pack.

[0031] During the use of the chainsaw 10, since the contact portion 161 of the battery pack unlocking member 160 is exposed to the outside of the housing 100, and there are foreign objects such as tree branches in the surrounding environment during the operation of the chainsaw 10, the chain saw 10 may come into contact with foreign objects such as tree branches in the outside world during operation. Foreign objects such as tree branches may sometimes touch the battery pack unlocking member 160, causing the battery pack to be unlocked and the battery pack and the electrode holder 170 to be separated. The chain saw 10 is powered off and cannot operate, and a safety accident may occur.

[0032] In view of this, the present disclosure provides an electric tool, in combination with Figure 1-2 In this embodiment, the electric tool is a chain saw 10, which includes: a housing 100; a battery pack, which is detachably connected to the housing 100; an electrode holder 170, which is arranged on the housing 100 and electrically connected to the battery pack; a battery pack unlocking member 160, which can drive the battery pack to connect or disconnect with the housing 100, and the battery pack unlocking member 160 includes a contact portion 161 for the operator to apply force; an unlocking protection member 150 is arranged opposite to the contact portion 161, and an insertion space is formed between the unlocking protection member 150 and the contact portion 161, and the insertion space includes an insertion port for the force member to enter, and the unlocking protection member 150 is configured to unlock the battery pack only when the force member enters the insertion space through the insertion port and acts on the contact portion 161. The probability of the battery pack unlocking member 160 being accidentally touched is reduced, and the stability and safety of the battery pack when in use are ensured.

[0033] Specifically, the battery pack is electrically connected to the circuit system and the motor 110 in the chain saw 10 through the electrode holder 170. The battery pack unlocking member 160 controls the removal of the battery pack. The operator applies force to the contact portion 161 in the battery pack unlocking member 160 to change the state of the battery pack unlocking member 160, so that the battery pack unlocking member 160 is converted from a locked battery pack state to a released battery pack state. The unlocking protection member 150 is arranged opposite to the free side of the contact portion 161, and surrounds the battery pack unlocking member 160 in multiple directions to form an insertion space, so that the force-applying member cannot apply force to the contact portion 161 in multiple directions, and can only be inserted and force-applied through the insertion port reserved in the insertion space. Foreign objects that scratch the chain saw 10 from the outside cannot apply force to the contact portion 161, and can only actively apply force from the insertion port to move the contact portion 161, thereby unlocking the battery pack, avoiding unlocking the battery pack due to accidental contact, and ensuring the stability and safety of the battery pack installation.

[0034] In one embodiment, the battery pack unlocking member 160 is disposed on the housing 100, and an unlocking protection member 150 is disposed opposite to the outer side of the battery pack unlocking member 160, so that the user can only contact the battery pack unlocking member 160 from the insertion port. In another embodiment, the battery pack unlocking member 160 can also be disposed on the battery pack, and the user contacts the battery pack unlocking member 160 from the insertion port and applies force to the battery pack unlocking member 160.

[0035] In a specific embodiment, the housing 100 of the chain saw 10 includes a left half shell and a right half shell, and the left half shell and the right half shell are connected to form the housing 100 of the chain saw 10; the front side of the housing 100 is provided with a motor chamber for installing the motor 110, and the rear side of the housing 100 is provided with a handle 130 for the convenience of the operator to hold. A battery pack slot is also provided between the handle 130 and the motor chamber, and the battery pack is detachably provided in the battery pack slot. The electrode holder 170 is provided on the bottom side of the battery pack slot, and can be provided on the left side, the right side, etc.; the electrode holder 170 is electrically connected to the battery pack to provide power to the motor 110.

[0036] In one embodiment of the present disclosure, in combination with reference to Figure 3 When the chain saw 10 is placed on a horizontal plane in a non-operating state, an insertion port is formed directly above the insertion space, and the horizontal plane is a plane perpendicular to the plumb line. Force can be applied to the contact portion 161 from directly above, which is convenient for the user to operate.

[0037] Specifically, the upper part of the insertion space is the upper part of the insertion space when the chain saw 10 is placed on a horizontal plane. When the unlocking protection member 150 is disposed opposite to the outer side of the battery pack unlocking member 160, a space is formed between the battery pack unlocking member 160 and the unlocking protection member 150, which is the insertion space. The insertion port is formed above the insertion space, and the user can reach into the insertion space from the insertion port and apply force to the contact portion 161 of the battery pack unlocking member 160.

[0038] In other embodiments, when the chain saw 10 is placed on a horizontal surface in a non-working state, an insertion opening is formed on the side of the insertion space, and the user applies force to the contact portion from the side to achieve unlocking.

[0039] In one embodiment of the present disclosure, in combination with reference to Figure 3-4 The spacing of the insertion space in the first direction is 8mm-18mm, and the first direction is perpendicular to the force direction of the force applying member. This facilitates the user to reach into the insertion space and prevents foreign objects from reaching into the insertion space.

[0040] Specifically, the spacing of the insertion space in the first direction is H in the figure. Specifically, it can be 8mm, 10mm, 15mm and 18mm, etc. The specific size of the spacing H of the insertion space can be selected according to the use requirements and is not specifically limited. If the spacing H of the insertion space is less than 8mm, it may cause the user's fingers to be unable to extend from the insertion port into the insertion space, reducing the user's experience. If the spacing H of the insertion space in the first direction is greater than 18mm, when the chain saw 10 is used to work, the battery pack unlocking part 160 may still be affected by external foreign matter, causing the external foreign matter to touch the battery pack unlocking part 160, causing the battery pack to be unlocked.

[0041] In one embodiment of the present disclosure, when the chain saw 10 is placed on a horizontal plane in a non-working state, the length of the orthographic projection of the unlocking protection member 150 on the horizontal plane is greater than the length of the orthographic projection of the battery pack unlocking member 160 on the horizontal plane, and the horizontal plane is a plane perpendicular to the plumb line. In this way, the battery pack unlocking member 160 is surrounded on the side to prevent foreign objects from touching the battery pack unlocking member 160 from the side and applying force to it.

[0042] Specifically, the length of the unlocking protection member 150 and the battery pack unlocking member 160 is the length of the second direction, wherein the second direction is perpendicular to the first direction in the horizontal plane. Therefore, the side of the unlocking protection member 150 exceeds the side of the battery pack unlocking member 160, and the side of the battery pack unlocking member 160 is blocked inside by the side of the unlocking protection member 150, and the battery pack unlocking member 160 cannot be touched from the side from the outside.

[0043] In a specific embodiment, the contour of the unlocking protection member 150 facing the side surrounds the battery pack unlocking member 160 , and the upper portion of the battery pack unlocking member 160 is exposed to form an insertion space.

[0044] In one embodiment of the present disclosure, the orthographic projection of the battery pack unlocking member 160 on the horizontal plane includes a first enclosing structure, and the orthographic projection of the unlocking protection member 150 on the horizontal plane includes a second enclosing structure, and the first enclosing structure and the second enclosing structure are arranged opposite to each other to define an insertion space, thereby ensuring that foreign objects from the outside cannot touch the battery pack unlocking member 160 from the side, thereby preventing the chain saw 10 from being unable to work due to power failure.

[0045] In a specific embodiment, when the chain saw 10 in a non-working state is placed on a horizontal plane, the first enclosing structure of the battery pack unlocking piece 160 can be U-shaped, and the second enclosing structure of the unlocking protection piece 150 can be flat-plate-shaped. The flat-plate-shaped unlocking protection piece 150 is arranged at or inside the opening of the U-shaped structure of the battery pack unlocking piece 160 to enclose an insertion space.

[0046] In another specific embodiment, when the chain saw 10 in a non-working state is placed on a horizontal plane, the first enclosing structure of the battery pack unlocking piece 160 is flat-plate-shaped, and the second enclosing structure of the unlocking protection piece 150 is U-shaped. The flat-plate-shaped battery pack unlocking piece 160 is arranged at the opening of the U-shaped structure of the unlocking protection piece 150, and together they form an insertion space with the upper part as an insertion port.

[0047] In another specific embodiment, the first enclosing structure and the second enclosing structure are both U-shaped structures, and the U-shaped structure of the first enclosing structure is inside the U-shaped structure of the second enclosing structure, and the openings are opposite to each other.

[0048] In another embodiment, the first enclosing structure and the second enclosing structure are both flat structures, the battery pack unlocking member 160 is provided on both sides of the housing 100, the housing 100 forms a recessed space, the battery pack unlocking member 160 is in the recessed space, and the unlocking protection member 150 blocks the side opening of the recessed space. This prevents foreign objects from touching the battery pack unlocking member 160 when the chain saw 10 is working, causing the chain saw 10 to lose power and fail to work.

[0049] In one embodiment of the present disclosure, when the electric tool is placed on a horizontal plane in a non-working state, the height of the orthographic projection of the unlocking protection member 150 on the vertical plane is greater than or equal to the height of the orthographic projection of the battery pack unlocking member 160 on the vertical plane.

[0050] Optionally, the unlocking protection member 150 is greater than or equal to the contact portion 161 in height. By setting the height of the unlocking protection member 150 to be at least higher than the height of the contact portion 161, the possibility of foreign objects from the outside touching the battery pack unlocking member 160 when the chain saw 10 is working can be further avoided, thereby further improving the safety of the chain saw 10.

[0051] In one embodiment of the present disclosure, the battery pack unlocking member 160 is rotatably connected to the battery pack or the housing 100 via a pivot shaft. When the chain saw 10 is placed on a horizontal plane in a non-working state, the plumb plane of the pivot shaft axis is used as a reference plane, and an active surface of the contact portion 161 has an inclination angle with the reference plane, and the horizontal plane and the plumb plane are perpendicular to each other. By acting on the active surface of the contact portion 161 with a single action, the battery pack unlocking member 160 is rotated relative to the housing 100 or the battery pack to unlock the battery pack, thereby improving operational convenience while ensuring that the contact portion is difficult to be accidentally touched.

[0052] Specifically, the action surface of the contact portion 161 faces the unlocking protection member 150, and the battery pack is unlocked by rotating the battery pack unlocking member 160. In order to facilitate the force member to act on the contact portion 161 from above, there is an inclined angle between the action surface of the contact portion 161 and the reference surface. The angle between the action surface and the reference surface can include 90 degrees, 95 degrees, 100 degrees, etc. The specific angle can be set according to the actual use needs of the user and is not specifically limited. An insertion space is formed between the action surface and the unlocking protection member 150, and the angle between the action surface and the reference surface should not be too small; when the angle between the action surface and the reference surface is too small, it may cause the user's finger to be difficult to extend into the insertion space, and it is difficult for the finger to abut against the action surface, making it difficult to unlock the battery pack or the housing 100. The angle between the action surface and the reference surface should not be too large. When the angle between the action surface and the reference surface is too large, it increases the possibility of foreign matter from the outside to resist the battery pack unlocking member 160, so that the unlocking protection member 150 cannot play its due protective role. By setting a suitable angle for force application, the safety of the chain saw 10 operation is improved.

[0053] In one embodiment of the present disclosure, see Figure 1-4 The chain saw 10 further includes a chip removal channel 143, which is lower than the insertion space. One end of the chip removal channel 143 is connected to the insertion space, and the other end is connected to the outside, so as to facilitate the discharge of chips dropped into the insertion space.

[0054] Specifically, the insertion space formed between the battery pack unlocking member 160 and the unlocking protection member 150 is specifically a receiving groove structure with an upper opening. Chip impurities will accumulate in the receiving groove. Therefore, by setting a chip discharge channel 143 lower than the insertion space and connecting the insertion space with the outside, the chips are discharged from the insertion space by gravity to avoid chip accumulation.

[0055] In one embodiment of the present disclosure, in combination with reference to Figure 3-4A first gap is provided between the battery pack unlocking member 160 and the housing 100, a first sealing step 162 is provided on the side of the battery pack unlocking member 160 opposite to the housing 100, and a second sealing step 163 is provided on the side of the housing 100 opposite to the battery pack unlocking member 160. The first sealing step 162 and the second sealing step 163 are overlapped with each other to block the first gap, and the matching gap between the first sealing step 162 and the second sealing step 163 is 0.5mm-1.2mm. By arranging the first sealing step 162 and the second sealing step 163 overlapping with each other, the possibility of chips entering the cavity of the electrode holder 170 from the first gap is reduced.

[0056] Specifically, the first sealing step 162 is provided on the battery pack unlocking member 160 and is located on the side of the contact portion 161 facing the housing 100. The second sealing step 163 is provided on the housing 100. The first sealing step 162 and the second sealing step 163 overlap and block the first gap. Since the electrode holder 170 is located below the battery pack unlocking member 160 and the battery pack unlocking member 160 moves when unlocked, the first gap may be exposed during the movement of the battery pack unlocking member 160. The provision of the first sealing step and the second sealing step can prevent chips from entering the cavity of the electrode holder 170 and affecting the use of the electrode holder 170.

[0057] In another embodiment, the first sealing step 162 and the second sealing step 163 also have mutually matching guiding arc surfaces. When force is applied to the action surface of the battery pack unlocking piece 160, the battery pack unlocking piece 160 can better rotate along the mutually matching guiding arc surfaces to better unlock the battery pack or the housing 100.

[0058] In order to prevent wood chips from entering the cavity of the electrode holder 170, the matching gap between the first sealing step 162 and the second sealing step 163 is further controlled to be 0.5mm-1.2mm to ensure the sealing effect. Specifically, it can be 0.5mm, 0.8mm, 1.2mm, etc. The specific gap size can be selected according to the actual usage.

[0059] In one embodiment of the present disclosure, the chain saw 10 further includes a shield 140, which is disposed outside the electrode holder 170 to protect the electrode holder 170, and a second gap is provided between the shield 140 and the battery pack unlocking member 160, and the battery pack unlocking member 160 is further provided with a third sealing step 141 on the side opposite to the shield 140, and the shield 140 is provided with a fourth sealing step 142 on the side opposite to the battery pack unlocking member 160, and the third sealing step 141 and the fourth sealing step 142 are overlapped up and down to block the second gap, and the matching gap between the third sealing step 141 and the fourth sealing step 142 is 0.5mm-1.2mm. To reduce the possibility of chips entering the cavity of the electrode holder 170 from the second gap.

[0060] In a specific embodiment, the unlocking protection member 150 is disposed on the shield 140 and is integrally disposed with the shield 140. The shield 140 is buckled on the outside of the housing 100, and a cavity for accommodating the battery pack unlocking member 160 and the electrode holder 170 is formed between the shield 140 and the housing 100; the third sealing step 141 is disposed on the side of the unlocking protection member facing outward and is lower than the contact portion 161, and the fourth sealing step 142 is disposed on the shield 140; the third sealing step 141 and the fourth sealing step 142 overlap up and down to block the second gap, so as to reduce the possibility of chips entering the cavity of the electrode holder 170 from the second gap.

[0061] In order to prevent wood chips from entering the cavity of the electrode holder 170, the matching gap between the third sealing step 141 and the fourth sealing step 142 is further controlled to be 0.5mm-1.2mm to ensure the sealing effect. Specifically, it can be 0.5mm, 0.8mm, 1.2mm, etc. The specific gap size can be selected according to the actual usage.

[0062] By providing the overlapping first sealing step 162 and the second sealing step 163, and the overlapping third sealing step 141 and the fourth sealing step 142, the possibility of external chips entering the cavity of the electrode holder 170 can be reduced, so as to better protect the electrode holder 170 and the internal circuits.

[0063] In one embodiment of the present disclosure, the chain saw 10 includes a handle 130, a cutting component, a transmission structure and a motor 110. The motor 110 and the transmission structure are disposed in the housing 100. The handle 130 and the cutting component are respectively disposed at opposite ends of the housing 100. The battery pack is located between the handle 130 and the cutting component. The motor 110 is electrically connected to the battery pack and drives the cutting component through the transmission structure to perform a cutting function.

[0064] Specifically, when the user uses the chain saw 10, the user holds the handle 130 with the cutting component facing outward relative to the user, so that the user can apply force to the object to be cut. The housing 100 accommodates the battery pack and the motor 110 between the handle 130 and the cutting component.

[0065] In a specific embodiment, the electric tool is a chain saw 10 , and the cutting component is a saw chain 120 .

[0066] In a specific embodiment, taking the electric tool as a chain saw 10 as an example, the chain saw includes a battery pack, a transmission structure, a housing 100, a saw chain 120, a guide plate, a handle 130, a chain cover and a motor 110. The housing 100 accommodates the motor 110 and the transmission structure, and the battery pack is detachably connected to the housing 100 to power the chain saw; the chain saw also includes a battery pack unlocking member 160 and an unlocking protection member 150, the battery pack unlocking member 160 is used to lock the battery pack, and the unlocking protection member 150 is arranged opposite to the free side of the battery pack unlocking member 160 facing the outside, the battery pack unlocking member 160 surrounds the battery pack unlocking member 160 to form an insertion space, and an insertion port is formed directly above the insertion space, allowing a force-applying member to act on the contact portion 161 of the battery pack unlocking member 160 from above the battery pack unlocking member 160; the battery pack unlocking member 160 0 is also higher than the contact portion 161, further avoiding accidental touching of the contact portion 161. There is a certain angle between the contact portion 161 and the reference plane, which is convenient for operation. In addition, a chip removal channel 143 is provided at the bottom of the insertion space to discharge the chips dropped into the insertion space.
