As long as the first body 1 and the second body 2 remain in abutment and stable in position, the cylindrical battery can remain stable in the cylindrical cavity for testing.

[0049] The two ends of the cylindrical cavity are connected to the outside world, so that the current lead can enter the cylindrical cavity through the two ends of the cylindrical cavity. The two ends of the cylindrical cavity can be selected to form an opening structure at the joint of the first main body 1 and the second main body 2 along the thickness direction of the second main body 2, and the current lead is passed through the opening structure. The current lead in the opening structure can be selected to abut against the inner wall of the opening structure, so that the opening structure can play a role in fixing the current lead.

[0051] The above-mentioned connection hole 24 can be selectively set on the first main body 1, and of course, the connection hole 24 can also be selected to be set on the second main body 2, as long as the connection hole 24 can extend toward the rectangular cavity, so that the connection hole 24 is connected to the rectangular cavity, and the current lead can pass through the connection hole 24 into the rectangular cavity and connect with the rectangular battery.

[0052] The size of the rectangular cavity can be selected to match the size of commonly used rectangular batteries, so that the rectangular battery is in contact with at least two inner walls of the rectangular cavity along the length direction of the second body 2 in the rectangular cavity.

[0053] When the battery testing fixture provided by the embodiment of the present disclosure is used, when it is necessary to detect a cylindrical battery, the second body 2 is placed on the ground, the first body 1 is rotated in a direction away from the second body 2, the cylindrical battery is placed on the side of the second body 2 away from the ground along the thickness direction of the second body 2, the two ends of the cylindrical battery are respectively connected to the current lead, the first body 1 is rotated, the first body 1 and the second body 2 are arranged opposite to each other in the thickness direction of the second body 2 and fit each other, so that the cylindrical battery is located in the cylindrical cavity formed by the first body 1 and the second body 2, and the current leads at both ends of the cylindrical battery are respectively passed through the two ends of the cylindrical cavity, so that the cylindrical battery is stably arranged in the cylindrical cavity formed by the first body 1 and the second body 2, and the cylindrical battery in the cylindrical cavity is detected through the current lead.

[0054] When it is necessary to detect the rectangular battery, the first body 1 is rotated toward the first position, the rectangular battery is placed on the side of the second body 2 along the length direction of the second body 2 for abutting against the first body 1, the current lead is passed through the connecting hole 24 to connect with the rectangular battery, and the first body 1 is rotated to the second position so that the rectangular battery can be set in the rectangular cavity formed by the first body 1 and the second body 2. In this process, the current lead remains in the state of being passed through the connecting hole 24 and connected to the rectangular battery, and the rectangular battery maintains the temperature of the position in the rectangular cavity. The first body 1 and the second body 2 are placed on a plane, and the rectangular battery is detected through the current lead.

[0056] Reference Figure 1 , Figure 4 and Figures 7 to 10 As shown, in some embodiments, the first body 1 includes a first surface 11, the second body 2 includes a second surface 21, the first surface 11 is recessed to form a first semicircular groove 12, and the second surface 21 is recessed to form a second semicircular groove 22, and connecting channels are provided on the side walls at both ends of at least one of the first semicircular groove 12 and the second semicircular groove 22; when the first body 1 is located in the first position, along the thickness direction of the second body 2, the first surface 11 and the second surface 21 are arranged opposite to each other and fit each other, and the first semicircular groove 12 and the second semicircular groove 22 are arranged opposite to each other, so that the first semicircular groove 12 and the second semicircular groove 22 together form a cylindrical cavity. In this way, the cylindrical battery is placed in any one of the first semicircular groove 12 and the second semicircular groove 22, and then the first main body 1 is rotated to the first position to confine the cylindrical battery in the cylindrical cavity, which facilitates the operation of setting the cylindrical battery in the cylindrical cavity. The wiring channel can ensure that the current lead enters the cylindrical cavity surrounded by the first semicircular groove 12 and the second semicircular groove 22.

[0057] Specifically, the first surface 11 and the second surface 21 are both planes, the middle position of the first surface 11 is recessed to form a first semicircular groove 12, and the middle position of the second surface 21 is recessed to form a second semicircular groove 22. When the first body 1 is in the first position, the extension directions of the first semicircular groove 12 and the second semicircular groove 22 can be selected to be consistent, so that the first semicircular groove 12 and the second semicircular groove 22 can jointly define a cylindrical cavity.

[0058] A plane perpendicular to the extension direction of the first semicircular groove 12 can be selected as the cross-section, and the cross-sectional shape of each part of the first semicircular groove 12 is semicircular. A plane perpendicular to the extension direction of the second semicircular groove 22 can be selected as the cross-section, and the cross-sectional shape of each part of the second semicircular groove 22 is semicircular, so that the first semicircular groove 12 and the second semicircular groove 22 can be arranged relative to each other to form a cylindrical cavity.

[0059] The above-mentioned first semicircular groove 12 has side walls on both sides of the first main body 1 along the direction in which the first semicircular groove 12 extends. Through holes can be selected to be respectively set on the two side walls of the first semicircular groove 12 as connection channels, so that the current lead can pass through the through holes into the first semicircular groove 12. The second semicircular groove 22 can also be selected to have side walls on both sides of the second main body 2 along the direction in which the second semicircular groove 22 extends, and through holes are respectively set on the two end side walls of the two second semicircular grooves 22 as connection channels, so that the current lead can pass through the through holes into the second semicircular groove 22; of course, through holes can also be selected to be set on both end side walls of the first semicircular groove 12 and the second semicircular groove 22 as connection channels. When the first surface 11 and the second surface 21 are in contact, the current lead can enter the cylindrical cavity through the connection channels.

[0060] Reference Figures 4 to 10 As shown, in some embodiments, a rectangular groove 23 is provided on the side of the second body 2 facing away from the second surface 21, and the rectangular groove 23 extends along the length direction of the second body 2. When the first body 1 is in the second position, the notch of the rectangular groove 23 is located on the side where the second body 2 and the first body 1 are in contact, so that the first body 1 and the rectangular groove 23 form a rectangular cavity. With such a configuration, the rectangular groove 23 can accommodate a rectangular battery, and the first body 1 can block the notch of the rectangular groove 23 when in the second position, so that the rectangular battery is stably arranged in the rectangular groove 23. When placing a rectangular battery, the rectangular battery is first inserted into the rectangular groove 23, and then the first body 1 is rotated to the second position so that the rectangular battery can be stably confined in the rectangular cavity surrounded by the rectangular groove 23 and the first body 1, which facilitates the operation of placing the rectangular battery in the rectangular cavity.

[0061] Specifically, the rectangular groove 23 extends along the length direction of the second main body 2, and the notch of the rectangular groove 23 is arranged opposite to the bottom of the groove. When the first main body 1 is in the second position, the first main body 1 and the second main body 2 are fitted on the side along the length direction of the second main body 2, so that the first main body 1 covers the notch of the rectangular groove 23, and the first main body 1 and the rectangular groove 23 together form a rectangular cavity; the connecting hole 24 can be selected to be arranged on the second main body 2 along the length direction of the second main body 2. The side of the notch of the rectangular groove 23 is facing away from the notch of the rectangular groove 23, that is, the connecting hole 24 is located at the bottom of the rectangular groove 23, so that the rectangular battery is inserted into the rectangular groove 23 through the notch of the rectangular groove 23, and the current lead is connected to the rectangular battery in the rectangular groove 23 through the connecting hole 24; of course, the connecting hole 24 can also be selected to be arranged on the second surface 21. Since there is no obstruction on the second surface 21 when the first main body 1 is in the second position, the user can pass the current lead through the connecting hole 24 and plug it into the rectangular battery in the rectangular groove 23.

[0062] The rectangular groove 23 matches the size of the rectangular battery in the length direction of the second body 2, so that after the rectangular battery is inserted into the rectangular groove 23, when the first body 1 rotates to the second position, one end of the rectangular battery abuts against the bottom of the rectangular groove 23, and the other end of the rectangular battery abuts against the side surface of the first body 1. The internal space of the rectangular groove 23 is a cuboid space, so that the shape of the internal space of the rectangular groove 23 matches the rectangular battery.

[0063] Reference Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the connection hole 24 is arranged on the second body 2 on the side of the notch facing away from the rectangular groove 23 along the length direction of the second body 2, and the connection hole 24 is connected with the rectangular groove 23. In this arrangement, the positive and negative electrodes of the rectangular battery are on one side of the battery and face the bottom of the rectangular groove 23, and the connection hole 24 extends to the bottom of the rectangular groove 23 on the side of the notch of the second body 2 facing away from the rectangular groove 23, so that the connection hole 24 is connected with the rectangular groove 23, which is convenient for the user to pass the current lead through the connection hole 24 and connect it with the positive and negative electrodes of the rectangular battery.

[0064] Specifically, the connecting hole 24 can be selected as a through hole on the second main body 2, so that the connecting hole 24 is connected to the notch of the rectangular groove 23 on the second main body 2, and a guide tube can be set on the side of the notch of the second main body 2 facing away from the rectangular groove 23, and the guide tube is set at the connecting hole 24, and the channel inside the guide tube is connected to the connecting hole 24, so that the current lead can enter the rectangular groove 23 through the guide tube and the connecting hole 24; the number of connecting holes 24 can be selected as two, and the two connecting holes 24 are arranged opposite to the positive and negative electrodes of the rectangular battery, so that the two current leads can enter the rectangular groove 23 through the two connecting holes 24 respectively and connect with the positive and negative electrodes of the rectangular battery; of course, the number of connecting holes 24 can also be selected as one, and the two current leads are first connected to the positive and negative electrodes of the rectangular battery, and then the two current leads are passed through one connecting hole 24 together, and then the rectangular battery is inserted into the rectangular groove 23, and the two current leads are insulated from each other so that the two current leads can detect the rectangular battery.

[0065] Reference Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the rectangular groove 23 is provided with an opening on one side of the second body 2 along the thickness direction thereof facing away from the second surface 21. With such a configuration, the battery being tested can be observed through the opening, and problems such as battery fire or bulging can be discovered in time. When the opening size is large, the rectangular battery can also be placed in and taken out of the rectangular groove 23 through the opening, thereby improving the convenience of placing and taking out the rectangular battery from the rectangular groove 23.

[0066] Specifically, the opening can be selected to be equal to the area of ​​the inner wall of the rectangular groove 23 on one side along the thickness direction of the second main body 2, so that the rectangular battery can be placed in the rectangular groove 23 through the opening. Of course, the size of the opening can also be selected to be smaller than the area of ​​the inner wall of the rectangular groove 23 on one side along the thickness direction of the second main body 2, so that the user can observe the working condition of the rectangular battery through the opening.

[0067] Reference Figure 1 , Figures 7 to 10 As shown, the first semicircular groove 12 and the second semicircular groove 22 extend along the width direction of the second body 2. With such arrangement, after the cylindrical battery is placed in the second semicircular groove 22 and the two ends of the cylindrical battery are connected to the current lead, the rotation of the first body 1 relative to the second body 2 does not contact the current lead, thereby preventing the current lead from being clamped and damaged during the rotation of the first body 1 relative to the second body 2.

[0068] Specifically, the first semicircular groove 12 and the second semicircular groove 22 extend along the width direction of the second body 2 , that is, the extending direction of the first semicircular groove 12 and the second semicircular groove 22 is the same as the direction of the rotation axis of the first body 1 relative to the second body 2 .

[0069] Reference Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, the side walls at both ends of the first semicircular groove 12 are respectively recessed on one side facing away from the first semicircular groove 12 to form a first connecting groove 121, and the first connecting groove 121 is a through groove along the extension direction of the first semicircular groove 12; the side walls at both ends of the second semicircular groove 22 are respectively recessed on one side facing away from the second semicircular groove 22 to form a second connecting groove 221, and the second connecting groove 221 is a through groove extending along the extension direction of the second semicircular groove 22; when the first main body 1 is located in the first position, along the thickness direction of the second main body 2, the two first connecting grooves 121 and the two second connecting grooves 221 are relatively arranged in a one-to-one correspondence, so that the first connecting groove 121 and the second connecting groove 221 jointly define a connecting channel. With such arrangement, when a cylindrical battery with current leads connected at both ends is placed in the first semicircular groove 12 or the second semicircular groove 22, the current lead can be placed in the first connecting groove 121 or the second connecting groove 221, so that the first connecting groove 121 and the second connecting groove 221 have a limiting effect on the position of the current lead during the process of placing the cylindrical battery in the cylindrical cavity, thereby preventing the first surface 11 and the second surface 21 from being fitted together so that the first body 1 and the second body 2 may pinch the current lead, thereby improving the user experience of the battery testing fixture.

[0070] Specifically, after the first connecting groove 121 and the second connecting groove 221 are opposite to each other, the space inside the first connecting groove 121 and the second connecting groove 221 together constitutes a connecting channel, so that the connecting channel connects the cylindrical cavity with the outside world; the size of the first connecting groove 121 and the second connecting groove 221 can be selected to be smaller than the first semicircular groove 12 and the second semicircular groove 22, so that the cylindrical battery can be located in the cylindrical cavity surrounded by the first semicircular groove 12 and the second semicircular groove 22, and at the same time, the cylindrical battery cannot escape from the cylindrical cavity through the connecting channel surrounded by the first connecting groove 121 and the second connecting groove 221.

[0071] In some embodiments, a first sensor is provided in the cylindrical cavity, and the first sensor is used to detect a specified physical quantity of the cylindrical battery in the cylindrical cavity. In this way, when the cylindrical battery is in the cylindrical cavity, the first sensor can detect the temperature of the cylindrical battery and the stress of the battery on the inner wall of the cylindrical cavity to assist in judging the quality of the battery.

[0072] Specifically, the first sensor can be set in the first semicircular groove 12, and of course, the first sensor can be set in the second semicircular groove 22, or the first sensor can be set in both the first semicircular groove 12 and the second semicircular groove 22; the specified physical quantity can be selected as temperature and stress, and the first sensor can be selected as a temperature sensor and a mechanical sensor, or the first sensor is a comprehensive sensor, so that the first sensor can detect the temperature of the cylindrical battery and the pressure of the cylindrical battery on the first semicircular groove 12 or the second semicircular groove 22.

[0073] In some embodiments, a second sensor is provided in the rectangular cavity, and the second sensor is used to monitor a specified physical quantity of the rectangular battery in the rectangular cavity. In this way, when the rectangular battery is in the rectangular cavity, the second sensor can detect the temperature of the rectangular battery and the stress of the battery on the inner wall of the rectangular cavity to assist in judging the quality of the battery.

[0074] Specifically, a second sensor can be selected to be set on the inner wall of the rectangular groove 23, or a second sensor can be selected to be set on the first body 1. When the first body 1 is located in the second position, at least part of the second sensor is located in the rectangular groove 23. The specified physical quantity can be selected as temperature and stress, and the second sensor can be selected as a temperature sensor and a mechanical sensor, or the first sensor can be a comprehensive sensor, so that the second sensor can detect the temperature of the cylindrical battery and the stress of the cylindrical battery on the rectangular groove 23.

[0075] Reference Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, a first heating element 13 is provided in the first body 1, and a second heating element 25 is provided in the second body 2. With such an arrangement, the first heating element 13 and the second heating element 25 can heat the cylindrical battery in the cylindrical cavity and the rectangular battery in the rectangular cavity, and the first heating element 13 and the second heating element 25 can regulate the temperature of the battery tested in the battery test fixture, so that the user can conveniently test the working conditions of the battery at different temperatures.

[0076] Specifically, grooves can be set on both the first body 1 and the second body 2, the first heating element 13 is inserted into the groove of the first body 1, and the second heating element 25 is inserted into the groove of the second body 2, so as to set the first heating element 13 inside the first body 1 and the second heating element 25 inside the second body 2.

[0077] Of course, the first body 1 and the second body 2 can also be manufactured using an injection molding process. When the first body 1 is manufactured, the first heating element 13 is set inside the first body 1, and when the second body 2 is heated, the second body 2 is set inside the second body 2.

[0078] Reference Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, one side of the first body 1 is recessed to form a first mounting groove, and the first heating element 13 is inserted into the first mounting groove, and one side of the second body 2 is recessed to form a second mounting groove, and the second heating element 25 is inserted into the second mounting groove. In this way, the first heating element 13 can be conveniently arranged inside the first body 1 through the first mounting groove, and the second heating element 25 can be conveniently arranged inside the second body 2 through the second mounting groove. When replacing the first heating element 13 and the second heating element 25, it is only necessary to pull the first heating element 13 out of the first mounting groove and the second heating element 25 out of the second mounting groove, which is convenient for users to replace the first heating element 13 and the second heating element 25.

[0079] Specifically, the first body 1 can be recessed on one side along the width direction of the second body 2 to form a first mounting groove, and the second body 2 can be recessed on one side along the width direction of the second body 2 to form a second mounting groove, the first mounting groove avoids the first semicircular groove 12, and the second mounting groove avoids the rectangular groove 23 and the second semicircular groove 22; the first mounting groove matches the shape and size of the first heating element 13, so that the first heating element 13 abuts against the inner wall of the first mounting groove, and the second mounting groove matches the shape and size of the second heating element 25, so that the second heating element 25 abuts against the inner wall of the second mounting groove, so that the first heating element 13 is stably set in the first mounting groove, and the second heating element 25 is stably set in the second mounting groove.

[0080] When the battery test fixture provided by the embodiment of the present disclosure is used, when testing a cylindrical battery, the second body 2 is placed on the ground, with the second surface 21 located on the side away from the ground, the first body 1 is rotated in a direction away from the first position, the two ends of the cylindrical battery are connected to the current leads, and then the cylindrical battery is placed in the second semicircular groove 22, and the current leads at both ends of the cylindrical battery are respectively placed in the two second connection grooves 221; the first body 1 is rotated to the first position, the first semicircular groove 12 and the second semicircular groove 22 form a cylindrical cavity, and the inner wall of the first semicircular groove 12 is aligned with the inner wall of the second semicircular groove 221. The inner walls of the two semicircular grooves 22 are in contact with the surface of the cylindrical battery, and the current leads at both ends of the cylindrical battery are located in the connection channel defined by the first connection groove 121 and the second connection groove 221. The cylindrical battery is detected through the current leads. During the cylindrical battery detection operation, the first sensor detects the working temperature of the cylindrical battery and the stress on the inner wall of the cylindrical cavity, and the first heating element 13 and the second heating element 25 work to change the temperature of the first body 1 and the second body 2, so that the cylindrical battery in the cylindrical cavity can be detected under different temperature environments.

[0081] When it is necessary to detect the rectangular battery, the first main body 1 is rotated toward the first position to expose the notch of the rectangular groove 23 on the second main body 2, and the rectangular battery is inserted into the rectangular groove 23 through the notch of the rectangular groove 23. The current lead is connected to the bolt and connected to the rectangular battery in the rectangular groove 23 through the connecting hole 24, or the connecting end of the rectangular battery is exposed in the connecting hole 24, so that the current lead is connected to the rectangular battery in the rectangular groove 23 through the connecting hole 24, and the rectangular battery is subjected to detection operation through the current lead; during the rectangular battery detection operation, the second sensor detects the working temperature of the rectangular battery and the stress on the inner wall of the rectangular cavity, and the first heating element 13 and the second heating element 25 are heated to change the temperature of the first main body 1 and the second main body 2, so that the rectangular battery in the rectangular cavity can be detected under different temperature environments.
