[0034] like Figures 1 to 3 As shown, the present disclosure provides a battery conversion device 100 for an electric device, the electric device has an installation cavity, the installation cavity is suitable for installing a type A battery, the battery conversion device 100 includes a main body 1 and a conductive member 2, the main body 1 has an insertion portion 11, the shape of the insertion portion 11 is adapted to the shape of the installation cavity, and the insertion portion 11 is suitable for detachably cooperating with the installation cavity.

[0035] An installation slot 12 is provided on one end of the main body 1 away from the insertion portion 11, and the installation slot 12 is suitable for installing a B-type battery;

[0036] The conductive member 2 is installed on the main body 1, and one end of the conductive member 2 is used for conductive connection with the electric device body, and the other end of the conductive member 2 extends into the installation groove 12 and is used for conductive connection with the B-type battery.

[0037] The battery conversion device 100 can be inserted into the installation cavity of the electric device through the insertion part 11 on the main body 1, and the type B battery can be installed in the installation groove 12 at the other end of the main body 1. The insertion part 11 and the installation groove 12 are both provided with conductive parts 2. The conductive parts 2 can conductively connect the electric device body and the type B battery so that the type B battery can power the electric device.

[0038] Through the above technical solution, the shape of the insertion portion 11 is adapted to the shape of the installation cavity, so that the battery conversion device 100 can be installed in the installation cavity that can only install type A batteries. The installation groove 12 for installing type B batteries is set at the other end away from the insertion portion 11, and the type B battery can be installed on the battery conversion device 100. The electric device body and the type B battery are conductively connected through the conductive member 2, so that the type B battery can power the electric device that can only install type A batteries. This arrangement allows the electric device to use not only type A batteries, but also type B batteries, which increases the types of batteries that can be used by the electric device and improves the utilization rate of type B batteries.

[0039] In the present disclosure, the electric device may be any electric device suitable for using the battery conversion device 100 provided by the present disclosure, for example, it may include but is not limited to an electric tool for tightening screws and nuts. The A-type battery and the B-type battery may also be any type (such as a nickel-hydrogen battery) or have any appropriate shape, which may be determined according to the specific electric device, and the present disclosure does not limit this.

[0040] In order to connect the battery conversion device 100 to an electric device, optionally, as Figure 1 and Figure 2 As shown, the battery conversion device 100 also includes a connector 3, the first end of the connector 3 is connected to the main body 1, and the second end of the connector 3 is provided with a clamping portion 31, and the clamping portion 31 is used to be detachably connected to the body of the electric device. The insertion portion 11 of the battery conversion device 100 cooperates with the installation cavity of the electric device, and the connector 3 is clamped with the electric device through the clamping portion 31 located at the second end, so that the insertion portion 11 can be kept in the installation cavity when the electric device is in use, so as to ensure that the battery supplies power to the electric device. The clamping portion 31 is detachably connected to the body of the electric device, so that the electric device can choose to directly use type A batteries or use type B batteries through the battery conversion device 100.

[0041] Alternatively, if Figure 1 and Figure 2As shown, the clamping portion 31 protrudes toward the first direction on the connecting member 3, and a guide slope 311 is provided on one side of the clamping portion 31 for cooperating with the electric device body, and the guide slope 311 gradually extends in a direction away from the first direction from the first end of the connecting member 3 to the second end. The first direction is perpendicular to the insertion direction of the battery conversion device 100 into the installation cavity. The clamping portion 31 can move along the first direction and has a tendency to move in a direction close to the electric device body. The clamping portion 31 protruding along the first direction can cooperate with the card slot of the electric device body to restrict the insertion portion 11 of the battery conversion device 100 in the installation cavity.

[0042] During the process of inserting the battery conversion device 100 into the installation cavity, the clamping portion 31 has a tendency to move toward the electric device body. The surface of the clamping portion 31 used to cooperate with the electric device body is set as a guide slope 311, so that during the process of the clamping portion 31 extending into the installation cavity, the thrust along the insertion direction received by the clamping portion 31 can be converted into a thrust for squeezing the clamping portion 31 away from the electric device, reducing the operation of squeezing the clamping portion 31 by the operator while installing the battery conversion device 100, thereby improving the installation convenience of the battery conversion device 100.

[0043] The present disclosure does not limit the specific structure that provides the locking force for the clamping portion 31 to remain in the clamping slot of the electric device. In one embodiment provided in the present disclosure, the connector 3 may further include an elastic arm, a first end of the elastic arm is connected to the main body 1, and a second end of the elastic arm is provided with the clamping portion 31.

[0044] In another embodiment provided by the present disclosure, Figure 1 As shown, the battery conversion device 100 further includes an elastic member, a guide groove 13 is formed on the main body 1, the opening of the guide groove 13 faces the first direction, the connecting member 3 is slidably arranged in the guide groove 13, and a stopper 14 is arranged at the opening of the guide groove 13, and the stopper 14 is suitable for abutting against the connecting member 3 to limit the position of the connecting member 3 in the first direction;

[0045] One end of the elastic member abuts against the side wall of the guide slot 13 , and the other end of the elastic member abuts against the side of the connector 3 away from the clamping portion 31 . The elastic member is used to provide a locking force for the connector 3 to remain in the clamping slot of the electric device.

[0046] The connecting member 3 is slidably disposed in the guide groove 13, and has a tendency to move in the first direction under the action of the elastic member, so that the connecting member 3 can be kept in the slot when it is matched with the slot of the electric device. At the same time, during the installation of the battery conversion device 100 and the electric device, the elastic member can be compressed, so that the connecting member 3 can move in the guide groove 13 in a direction away from the electric device to avoid the electric device body, so that the clamping portion 31 enters the installation cavity.

[0047] Furthermore, when the battery conversion device 100 is not mounted and adapted to the electric device, the stopper 14 can restrict the connector 3 within the guide groove 13 to prevent the connector 3 from falling out under the action of the elastic member.

[0048] To fix the elastic member, optionally, Figure 1 As shown, the connecting member 3 is provided with a cylindrical protrusion 32, the elastic member is sleeved on the cylindrical protrusion 32, and a receiving groove 131 is provided on the side wall of the guide groove 13. The end of the cylindrical protrusion 32 is in the receiving groove 131, and the end of the elastic member away from the connecting member 3 is pressed against the side wall of the receiving groove 131.

[0049] The cylindrical protrusion 32 is arranged on the side of the connecting member 3 away from the clamping portion 31, and the elastic member is sleeved on the cylindrical protrusion 32, so that one end of the elastic member can be fixed on the side of the connecting member 3 to prevent the elastic member from falling during the movement. The cylindrical protrusion 32 extends in a direction away from the first direction, and a receiving groove 131 is arranged on the side wall of the guide groove 13, so that when the connecting member 3 moves in a direction away from the first direction, the cylindrical protrusion 32 can be located in the receiving groove 131 to avoid the cylindrical protrusion 32.

[0050] To install a B-type battery, optionally, Figure 3 As shown, a first side plate 16 and two second side plates 17 are arranged on the first end surface 15 of the main body 1, the two second side plates 17 are arranged opposite to each other, the first side plate 16 is arranged between the two second side plates 17, the first side plate 16, the two second side plates 17 and the first end surface 15 jointly enclose a mounting groove 12, the mounting groove 12 has an insertion port 121 opposite to the first side plate 16, and the insertion port 121 is used for inserting a B-type battery into the mounting groove 12. The other end of the conductive member 2 is penetrated through the first end surface 15, and a connecting portion is arranged in the mounting groove 12, and the connecting portion is used to be detachably connected to the B-type battery.

[0051] The mounting groove 12 formed by the first side plate 16, the two second side plates 17 and the first end surface 15 can limit the position of the B-type battery in different directions, thereby ensuring that the B-type battery will not move easily during use. While the first side plate 16, the two second side plates 17 and the first end surface 15 are used to limit the position of the B-type battery, a connecting portion is also provided in the mounting groove 12, and the connecting portion can be detachably connected to the B-type battery, thereby ensuring that the B-type battery will not fall off during use.

[0052] One end of the conductive member 2 for connecting with the B-type battery is disposed in the mounting groove 12 , and can be conductively connected with the B-type battery when the B-type battery is installed in the mounting groove 12 .

[0053] Alternatively, if Figure 1 and Figure 3As shown, the main body 1 is further provided with a connecting protrusion 6, which is provided at the insertion port 121 of the main mounting groove 12, and a connecting hole is formed on the connecting protrusion 6, and the connecting hole is used to pass a connecting rope connected to the electric device body. The battery conversion device 100 can be connected to the electric device body through the connecting protrusion 6 and the connecting rope, thereby preventing the battery conversion device 100 from falling off during use. Even if it falls off, it will not be separated from the electric device body, and the battery conversion device 100 can also be prevented from being lost.

[0054] Alternatively, if Figure 3 As shown, the connection portion is configured as a card slot 171 provided on the inner wall of the second side plate 17, and the card slot 171 is used to engage with the card connection portion on the B-type battery. When the B-type battery is located in the installation slot 12, the card connection portion 31 on the B-type battery is located in the card slot 171 and can be maintained in the card slot 171. Through the cooperation between the card slot 171 and the card connection portion on the B-type battery, the connection state between the B-type battery and the battery conversion device 100 during use can be ensured.

[0055] In order to further enhance the strength of the second side plate 17, optionally, as Figure 1 , Figure 2 and Figure 3 As shown, the two second side plates 17 are both formed with arc-shaped protrusions 172 on the side away from the mounting groove 12. The arc-shaped protrusions 172, on the one hand, create a protrusion higher than the surface on the surface of the second side plate 17 away from the mounting groove 12, which is convenient for the operator to hold, and on the other hand, can also serve as a reinforcement structure of the second side plate 17, increase the thickness and bending resistance of the second side plate 17, and thus improve the structural strength of the second side plate 17.

[0056] Alternatively, if Figure 1 As shown, the conductive member 2 includes two first pole pieces 21, two second pole pieces 22 and two electrical connection lines 23. The two first pole pieces 21 are respectively used to connect to the positive electrode and the negative electrode of the B-type battery, and the two second pole pieces 22 are respectively used to connect to the positive electrode and the negative electrode of the electric device, and the first pole piece 21 and the second pole piece 22 are electrically connected through the corresponding electrical connection line 23.

[0057] The main body 1 is provided with a first support structure 18 and a plurality of second support structures 19. The plurality of second support structures 19 are arranged around the first support structure 18. The upper surface of the first support structure 18 is higher than the upper surface of the second support structure 19. The lower ends of the first support structure 18 and the plurality of second support structures 19 are arranged near the mounting groove 12. The upper end of the first support structure 18 is used to be inserted into the body of the electric device. Two second pole pieces 22 are respectively arranged at the upper ends of the first support structure 18, and the first pole piece 21 is penetrated through the bottom wall of the mounting groove 12. The two second pole pieces 22 can be installed on the first support structure 18, and the two first pole pieces 21 can be installed on the side of the bottom wall of the mounting groove 12 away from the mounting groove 12, and pass through the mounting groove 12, so that one end of the first pole piece 21 is located in the mounting groove 12, and the first pole piece 21 and the second pole piece 22 are electrically connected through the electrical connection line 23. Among them, the first pole piece 21 is located between the first support structure 18 and the second support structure 19.

[0058] In this arrangement, since the second pole piece 22 is mounted on the upper end of the first support structure 18, the upper end of the first support structure 18 is used to be inserted into the body of the electric device (i.e., the installation cavity), that is, the first support structure 18 can ensure that the second pole piece 22 of the conductive member 2 can be connected to the positive and negative electrodes of the electric device, providing support for the conductive member 2. Since the first pole piece 21 is mounted between the first support structure 18 and the second support structure 19, the first support structure 18 and the second support structure 19 can not only be used to install the conductive member 2, but also protect the conductive member 2 so that it will not be damaged during use.

[0059] Alternatively, if Figure 1 , Figure 2 and Figure 3 As shown, the battery conversion device 100 further includes a housing 5, which is detachably connected to the main body 1, and the housing 5 is covered on the upper end of the main body 1.

The housing 5 includes a first part adapted to the shape of the first support structure 18 and a second part adapted to the shape of the second support structure 19, and the first part and the second part are connected, and the connected first part and the second part and the first support structure 18 form an insertion portion 11 that cooperates with the installation cavity of the electric device.

[0060] The second pole piece 22 and the first pole piece 21 are arranged on the main body 1 and are electrically connected through the electrical connection line 23. The outer shell 5 is covered on the upper end of the main body 1. The shape of the outer shell 5 is adapted to the installation cavity of the electric device so that the second pole piece 22 can be connected to the positive and negative poles of the electric device, thereby electrically connecting the B-type battery to the electric device.

[0061] Furthermore, since the second pole piece 22 is electrically connected to the positive and negative poles of the electric device through the via 51 located on the outer shell 5, the other components of the conductive part 2 are all located inside the outer shell 5. The outer shell 5 can also protect the conductive part 2 installed on the main body 1 and extend the service life of the battery conversion device 100.

[0062] Optionally, a through hole is formed on the shell 5 , and a bolt hole is provided on the main body 1 , and the bolt 7 can pass through the through hole and connect with the bolt hole to connect the shell 5 and the main body 1 .
