[0034] like Figures 1 to 3As shown, the embodiment of the present invention provides a locking device for preventing a battery pack from popping out, which is applied to a battery pack 3 in an electric tool 1. The electric tool 1 is provided with a battery compartment 12, and the battery pack 3 is inserted into the battery compartment 12. The locking device 2 for preventing the battery pack from popping out includes: a base bracket 21, which is fixedly arranged in the battery compartment 12 of the electric tool 1 and is located above the battery pack 3; a first rotating member 22, which has a first end 223 and a second end 224 opposite to each other, the first end 223 being rotatably arranged on the base bracket 21 and having an opening 221, and the second end 224 being provided with a A clamping portion 222 that can clamp the battery pack 3; a first elastic member 23, which is arranged on the base bracket 21 and connected to the first end 223 of the first rotating member 22; a second rotating member 24, having a third end 241 and a fourth end 242 opposite to each other, the second rotating member 24 is located in the opening 221 and is rotatably arranged on the base bracket 21; the third end 241 of the second rotating member 24 is embedded in the bottom of the first rotating member 22; a trigger button 25, which is arranged on the power tool 1 and extends into the battery compartment 12, and the bottom of the trigger button 25 is abutted against the fourth end 242 of the second rotating member 24.

[0035] A limiting plate 14 is provided in the battery compartment 12 and is located above the first rotating member 22 to limit the rotation angle of the first rotating member 22 .

[0036] In this embodiment, the locking device 2 for preventing the battery pack from popping out is fixedly connected to the power tool 1 by a pin 27; a holding groove 31 is provided on the battery pack 3 for engaging with the holding portion 222. When the battery pack 3 is located in the battery compartment 12 of the power tool 1, the locking device 2 for preventing the battery pack from popping out can be snap-connected with the holding groove 31 of the battery pack 3, thereby locking the battery pack 3 and preventing the battery pack 3 from falling off due to vibration.

[0037] See also Figure 5 As shown, in this embodiment, the second rotating member 24 further includes a rotating portion 243, and the third end 241 and the fourth end 242 of the second rotating member 24 are connected to each other through the rotating portion 243. The second rotating member 24 is rotatably connected to the base bracket 21 through the rotating portion 243. This arrangement allows the third end 241 and the fourth end 242 of the second rotating member 24 to perform a lever motion with the rotating portion 243 as the central axis when the second rotating member 24 rotates. That is, when the third end 241 rotates upward, the fourth end 242 rotates downward, and when the third end 241 rotates downward, the fourth end 242 rotates upward.

[0038] In this embodiment, when the battery pack 3 needs to be unlocked and separated from the power tool 1, by pressing the trigger button 25, the trigger button 25 moves toward the direction of the battery pack 3 and links the fourth end 242 of the second rotating member 24 to rotate downward, and causes the third end 241 of the second rotating member 24 to rotate upward and tilt up; because the bottom of the first rotating member 22 is located on the top of the third end 241 of the second rotating member 24, the third end 241 of the second rotating member 24 rotates upward and drives the second end 224 of the first rotating member 22 to rotate upward and tilt up, This forms a tilted state, thereby separating the holding portion 222 of the first rotating member 22 from the holding groove 31 of the battery pack 3, thereby realizing the unlocking function of the battery pack 3 by the locking device 2 for preventing the battery pack from popping out. A pop-up device 13 for popping out the battery pack 3 is provided in the battery compartment 12. Since the battery pack 3 is connected to the pop-up device 13 when it is in the battery compartment 12, when the locking device 2 for preventing the battery pack from popping out unlocks the battery pack 3, the user triggers the pop-up device 13, causing the battery pack 3 to be ejected from the outside of the battery compartment 12 by the pop-up device 13.

[0039] Furthermore, since the first rotating member 22 stretches the first elastic member 23 while rotating upward, when the user releases the trigger button 25, the locking device 2 for preventing the battery pack from popping out is no longer pressed by external force, and the first elastic member 23 is reset by elastic force. While the first elastic member 23 is reset, it also drives the first end 224 of the first rotating member 22 to rotate downward and become a horizontal state, and the first rotating member 22 drives the third end 241 of the second rotating member 24 to rotate downward and flip into a horizontal state. At the same time, the fourth end 242 of the second rotating member 24 is rotated and tilted upward using the lever principle, and the fourth end 242 of the second rotating member 24 drives the trigger button 25 to move upward, so that the trigger button 25 is reset to facilitate the next press.

[0040] In this embodiment, since an opening 221 is provided on the first rotating member 22, the second rotating member 24 can be rotatably installed in the opening 221, thereby reducing the overall size of the locking device 2 for preventing the battery pack from popping out, making the overall locking device 2 for preventing the battery pack from popping out more compact, and saving more installation space for the power tool 1.

[0041] See also Figure 8 As shown, in this embodiment, when the first rotating member 22 rotates upward, it contacts the limit plate 14, thereby preventing the first rotating member 22 from rotating. The user cannot continue to press the trigger button 25 downward, which helps prevent the first rotating member 22 from rotating too much. The trigger button 25 passes through the limit plate 14 and contacts the fourth end 242 of the second rotating member 24.

[0042] In one embodiment, the rotation angle of the first rotating member 22 is 0° to 7.348°.

[0043] In this embodiment, when the rotation angle of the first rotating member 22 is 0°, the clamping portion 222 of the first rotating member 22 is fixed to the clamping groove 31 of the battery pack 3; when the rotation angle of the first rotating member 22 is 7.348°, the clamping portion 222 of the first rotating member 22 is separated from the clamping groove 31 of the battery pack 3, and the top of the first rotating member 22 is abutted against the limit plate 14; by specifically limiting the rotation angle of the first rotating member 22, when the first rotating member 22 rotates, it is possible to more accurately avoid the first rotating member 22 from rotating too much and requiring a larger rotation space; through such a setting, the first rotating member 22 rotates in a smaller rotation space, which can not only meet the locking and unlocking requirements of the battery pack 3, but also enable the anti-battery pack pop-up locking device 2 of the present application to have a more compact spatial structure.

[0044] See also Figure 3 and Figure 6 As shown, in one embodiment, the base bracket 21 includes a base 214 and a first mounting portion 211 . The first mounting portion 211 is disposed on the base 214 , and the first end 223 of the first rotating member 22 is rotatably connected to the first mounting portion 211 .

[0045] In this embodiment, the first rotating member 22 is rotatably connected to the first mounting portion 211 via a pin 27. When the second rotating member 24 drives the first rotating member 22 to rotate, the first rotating member 22 can rotate around the first mounting portion 211, so that the clamping portion 222 of the first rotating member 22 can be stably lifted upward to release the lock of the clamping portion 222 on the battery pack 3.

[0046] In one embodiment, the first elastic member 23 is a torsion spring. The first elastic member 23 is sleeved on the first mounting portion 211 and connected to the first end 223 of the first rotating member 22 .

[0047] In this embodiment, when the first rotating member 22 rotates, the first elastic member 23 can provide a resetting elastic force for the first rotating member 22 , and the first rotating member 22 is automatically reset by the elastic force of the first elastic member 23 , thereby facilitating the first rotating member 22 to rotate again.

[0048] In one embodiment, the base bracket 21 further includes a second mounting portion 212 , and the second rotating member 24 is rotatably mounted on the second mounting portion 212 and located in the opening 221 ;

[0049] A groove 213 is defined on the base bracket 21 . When the trigger button 25 presses the fourth end 242 of the second rotating member 24 , the fourth end 242 of the second rotating member 24 is received in the groove 213 .

[0050] In this embodiment, the angle between the third end 241 and the fourth end 242 of the second rotating member 24 is an acute angle, so that the shape of the second rotating member 24 is "V"-shaped, and the rotating portion 243 of the second rotating member 24 is rotatably mounted on the second mounting portion 212. Such an arrangement allows the third end 241 and the fourth end 242 of the second rotating member 24 to perform lever motion around the second mounting portion 212.

[0051] In this embodiment, when the trigger button 25 presses the fourth end 242 of the second rotating member 24, the fourth end 242 of the second rotating member 24 rotates downward and can be accommodated in the groove 213, and the third end 241 of the second rotating member 24 rotates upward to drive the first rotating member 22 to rotate upward; the setting of the groove 213 makes the second rotating member 24 rotate downward a larger distance range, and has a more compact installation structure while increasing the rotation range, thereby reducing the volume of the locking device 2 for preventing the battery pack from popping out.

[0052] See also Figure 3 and Figure 4 As shown, in one embodiment, the locking device 2 for preventing the battery pack from popping out further includes a second elastic member 26, and the trigger key 25 includes a pressing portion 251 and a resisting portion 252. One end of the second elastic member 26 is connected to the pressing portion 251, and one end of the resisting portion 252 is connected to the pressing portion 251, and the other end of the resisting portion 252 is in contact with the fourth end 242 of the second rotating member 24.

[0053] In this embodiment, when a user presses the pressing portion 251 downward, the pressing portion 251 causes the abutting portion 252 to move downward, which in turn causes the fourth end 242 of the second rotating member 24 to rotate downward. One end of the second elastic member 26 is connected to the pressing portion 251. When the pressing portion 251 moves downward, it also causes the second elastic member 26 to move downward, allowing the other end of the second elastic member 26 to abut against the top of the first rotating member 22. This causes the pressing portion 251 to squeeze the second elastic member 26. When the user releases the pressing portion 251, the pressing portion 251 is moved upward by the elastic force of the second elastic member 26, thereby facilitating the resetting of the trigger key 25.

[0054] In a more specific embodiment, the second elastic member 26 is a compression spring, which is sleeved around the outer periphery of the resisting portion 252 and connected to the pressing portion 251 .

[0055] In this embodiment, because the second elastic member 26 is sleeved around the outer periphery of the abutment portion 252, it can fit tightly against the abutment portion 252. Therefore, when the pressing portion 251 is pressed, the second elastic member 26 is evenly compressed, generating a stable elastic force. Furthermore, the second elastic member 26 is tightly wrapped around the abutment portion 252, thus not occupying additional space and maintaining the compactness of the battery pack anti-ejection locking device 2.

[0056] More specifically, the bottom of the second elastic member 26 corresponds to the top of the limit plate 14. When the trigger key 25 is pressed, the bottom of the second elastic member 26 abuts against the limit plate 14, so that the second elastic member 26 obtains elastic force to reset the trigger key 25.

[0057] See also Figure 4 As shown, in one embodiment, the other end of the resisting portion 252 is provided with an inclined surface 2521 , and the inclined surface 2521 is inclined toward the pressing portion 251 .

[0058] In this embodiment, when the interference portion 252 presses the fourth end of the second rotating member 24 to rotate downward, due to the setting of the inclined surface 2521, the fourth end 242 of the second rotating member 24 can avoid being restricted by the interference portion 252 when rotating downward, thereby increasing the rotation range of the fourth end 242 of the second rotating member 24. Compared with the flat setting of the other end of the interference portion 252, the utility model is set in this way to increase the downward rotation range of the fourth end 242 of the second rotating member 24, thereby ensuring that the second rotating member 24 can lift the first rotating member 22 upward, thereby achieving the purpose of separating the clamping portion 222 of the first rotating member 22 from the clamping groove 31 of the battery pack 3.

[0059] In one embodiment, the pressing portion 251 is provided with anti-skid textures or anti-skid protrusions (not shown in the figure) to increase friction during user operation.

[0060] In this embodiment, the anti-slip texture or anti-slip protrusions are provided on the surface of the pressing portion 251. Specifically, they can be in the form of tiny concave-convex patterns, stripes, dots, or other shapes. This arrangement can increase the friction between the user's finger and the pressing portion 251, thereby preventing slipping or misoperation caused by wet or greasy hands or insufficient strength during operation.

[0061] See also Figure 7 As shown, an embodiment of the present invention provides an electric tool 1, which includes a housing 11, a battery compartment 12, an ejection device 13, and the locking device 2 for preventing the battery pack from ejecting. The battery compartment 12 is opened in the housing 11, and the ejection device 13 is arranged in the battery compartment 12. A battery pack 3 is inserted into the battery compartment 12, and the battery pack 3 abuts against the ejection device 13. The locking device 2 for preventing the battery pack from ejecting is arranged on the housing 11 and can be locked with the battery pack 3.

[0062] In this embodiment, when the battery pack 3 needs to be installed in the battery compartment 12, the locking device 2 for preventing the battery pack from popping out is pressed so that the holding portion 222 of the locking device 2 for preventing the battery pack from popping out moves upward. After the battery pack 3 is installed in the battery compartment 12, it abuts against the pop-up device 13. Then, the locking device 2 for preventing the battery pack from popping out is released so that the locking device 2 for preventing the battery pack from popping out moves downward and is clamped with the holding slot 31 of the battery pack 3, thereby preventing the battery pack 3 from falling off due to vibration. When the battery pack 3 needs to be taken out of the battery compartment 12, the locking device 2 for preventing the battery pack from popping out is pressed so that the locking device 2 for preventing the battery pack from popping out is separated from the battery pack 3, and the battery pack 3 pops out of the battery compartment 12 through the pop-up device 13.

[0063] The utility model provides a locking device and power tool for preventing the battery pack from popping out, which can lock or unlock the battery pack 3 and reduce the overall size of the locking device 2 for preventing the battery pack from popping out; an opening 221 is provided on the first rotating member 22, and the second rotating member 24 is rotatably arranged in the opening 221. Such an arrangement reduces the overall size of the locking device 2 for preventing the battery pack from popping out; secondly, when the user presses the trigger button 25, the trigger button 25 drives the third end 241 of the second rotating member 24 to rotate upward, so that the third end 241 of the second rotating member 24 drives the first rotating member 22 to rotate upward, and the battery pack 3 is installed in the battery compartment 12 of the power tool 1. Then the user releases the trigger button 25, so that the first rotating member 22 is reset, and the clamping portion 222 of the first rotating member 22 is locked with the battery pack 3, thereby realizing the locking of the battery pack 3 by the locking device 2 for preventing the battery pack from popping out, avoiding the problem that the battery pack 3 is easily separated from the power tool 1 due to vibration. When the battery pack 3 needs to be detached from the power tool 1 , the user presses the trigger button 25 to separate the clamping portion 222 of the first rotating member 22 from the battery pack 3 , thereby allowing the battery pack 3 to be ejected from the battery compartment 12 by the ejection device 13 .
