Description

Technical Field

[0001] This utility model belongs to the field of jig technology, and in particular relates to an integrated battery jig. Background Technology

[0002] After the battery body is installed inside the battery casing and electrolyte is injected into the casing, it still needs to undergo processes such as settling and formation. When the battery is in the settling state, it needs to be placed inside a fixture, and the positive and negative pressures inside the battery and inside the fixture need to be equal. When the battery is in the formation state, the inside of the battery needs to be adjusted to a negative pressure state, and the outside of the battery needs to be adjusted to a positive pressure state.

[0003] In existing technologies, to meet the requirements of battery settling and formation processes, two valve seats are required on the battery fixture. One valve seat connects to the inside of the battery, and the other valve seat connects to the chamber where the battery is located. An external air pump controls the pressure inside and outside the battery through the two valve seats. However, the design of two valve seats increases the manufacturing cost and space occupied by the battery fixture. Summary of the Invention

[0004] The present invention addresses the technical problems of high manufacturing cost and large space occupation of existing battery fixtures by providing an integrated battery fixture.

[0005] To address the above problems, the first embodiment of this utility model provides an integrated battery fixture, including a housing, a switching valve, and a connector mounted on the housing; the housing is provided with a first channel, a second channel, and a receiving space for accommodating a battery, the first channel being connected to the inner cavity of the battery located in the receiving space through the connector, and the second channel being connected to the receiving space;

[0006] The switching valve includes a valve core and a valve seat mounted on the housing. The valve seat is also provided with a control hole, a second valve hole, and a first valve hole that communicates with the first channel. The valve core is installed in the control hole and is used to control the second channel to communicate with either the first valve hole or the second valve hole.

[0007] Optionally, the valve core includes a valve stem that is slidably inserted into the control hole, and the valve stem is provided with a sealing part that abuts against the inner wall of the control hole;

[0008] The valve seat is also provided with a first air passage, a second air passage and a third air passage, all of which are connected to the control hole. The first air passage is connected to the first valve hole and the first channel, the second air passage is connected to the second channel, and the third air passage is connected to the second valve hole.

[0009] When the valve stem drives the sealing part to slide between the first air passage and the second air passage, the first valve hole is connected to the first channel through the first air passage, and the second valve hole is connected to the second channel through the third air passage, the control hole, and the second air passage.

[0010] When the valve stem drives the sealing part to slide between the second air passage and the third air passage, the first valve hole connects to the first channel through the first air passage, and the first valve hole also connects to the second channel in sequence through the first channel, the control hole, and the second air passage.

[0011] Optionally, the first air passage, the second air passage, and the third air passage are connected to the control hole through the first opening, the second opening, and the third opening, respectively, and the first opening, the second opening, and the third opening are sequentially spaced along the axial direction of the control hole.

[0012] When the sealing part is located between the first opening and the second opening, the first valve hole is connected to the first channel through the first air passage, and the second valve hole is connected to the second channel through the third air passage, the control hole, and the second air passage.

[0013] When the sealing part is located between the second opening and the third opening, when the valve stem drives the sealing part to slide between the second air passage and the third air passage, the first valve hole connects to the first channel through the first air passage, and the first valve hole also connects to the second channel in sequence through the first channel, the control hole, and the second air passage.

[0014] Optionally, the valve core further includes a magnetic attractor installed in the control hole for attracting the valve stem; the magnetic attraction of the magnetic attractor to the valve stem causes the sealing portion to be located in the control hole between the second opening and the third opening.

[0015] Optionally, the sealing part is provided with an annular groove, and the valve core further includes a sealing ring fitted in the annular groove.

[0016] Optionally, the first air passage and the second air passage are located on the same side of the control hole, and the first air passage and the third air passage are located on opposite sides of the control hole.

[0017] Optionally, the valve stem is provided with a control part located outside the control hole.

[0018] Optionally, the switching valve further includes a first connector inserted into the first valve hole and a second connector inserted into the second valve hole; the first connector is used to control the opening and closing of the first valve hole, and the second connector is used to control the opening and closing of the second valve hole.

[0019] Optionally, the integrated battery fixture further includes a formation probe mounted on the housing, the formation probe being electrically connected to the battery located in the housing space.

[0020] In this invention, when the valve core moves in the control hole to the point where the first valve hole connects to the second channel, and the second valve hole does not connect to the second channel, the first valve hole connects to the inner cavity of the battery through the first channel and the connector. The first valve hole also connects to the accommodating space through the control hole, the first valve hole, and the connector. Thus, the inner cavity of the battery and the accommodating space can be drawn into a high-pressure state through the first valve hole to complete the high-pressure static placement of the battery.

[0021] When the valve core moves in the control hole to the point where the second valve hole connects to the second channel, and the first valve hole does not connect to the second channel, the first valve hole connects to the inner cavity of the battery through the first channel and the docking nozzle. The second valve hole, the control hole, and the second air passage connect to the accommodating space. The inner cavity of the battery can be drawn into a negative pressure state through the first valve hole, and the accommodating space can be adjusted into a positive pressure state through the second valve hole to complete the battery formation process.

[0022] In this invention, the pressure inside the battery cavity and the pressure in the housing space where the battery is located can be adjusted by the switching valve, which improves the integration of the integrated battery fixture. The integrated battery fixture has low manufacturing cost, occupies little space, and is easy to transport. Attached Figure Description

[0029] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0030] It should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0031] like Figures 1 to 3 As shown in the figure, an integrated battery fixture provided by this utility model includes a housing 1, a switching valve 2, and a docking nozzle 3 installed on the housing 1. The housing 1 is provided with a first channel 11, a second channel 12, and a receiving space 13 for accommodating a battery 10. The first channel 11 is connected to the inner cavity 101 of the battery 10 located in the receiving space 13 through the docking nozzle 3, and the second channel 12 is connected to the receiving space 13. It can be understood that the housing 1 may include an upper housing and a lower housing detachably installed on the upper housing. The detachable connection between the upper housing and the lower housing facilitates the installation of the battery 10 in the receiving space 13. The first channel 11 and the docking nozzle 3 are always in communication. When the battery 10 is installed in the receiving space 13, the docking nozzle 3 will connect with the liquid injection hole on the battery 10, so that the first channel 11 is connected to the inner cavity 101 of the battery 10 through the docking nozzle 3.

[0032] The switching valve 2 includes a valve core 21 and a valve seat 22 mounted on the housing 1. The valve seat 22 is further provided with a control hole 221, a second valve hole 223, and a first valve hole 222 communicating with the first channel 11. The valve core 21 is installed in the control hole 221 and is used to control the second channel 12 to communicate with either the first valve hole 222 or the second valve hole 223. Understandably, the switching valve 2 has two states: one state is that the first valve hole 222 communicates with both the first channel 11 and the second channel 12; the other state is that the first channel 11 is always in a connected state; when the first valve hole 222 communicates with the first channel 11, the second valve hole 223 communicates with the second channel 12.

[0033] In this invention, when the valve core 21 moves in the control hole 221 to the point where the first valve hole 222 connects to the second channel 12, and the second valve hole 223 does not connect to the second channel 12, the first valve hole 222 connects to the inner cavity 101 of the battery 10 through the first channel 11 and the docking nozzle 3. The first valve hole 222 also connects to the accommodating space 13 through the control hole 221, the first valve hole 222, and the docking nozzle 3. Thus, the inner cavity 101 of the battery 10 and the accommodating space 13 can be drawn into a high-pressure state through the first valve hole 222 to complete the high-pressure static placement of the battery 10.

[0034] When the valve core 21 moves in the control hole 221 to the second valve hole 223 connecting to the second channel 12, and the first valve hole 222 not connecting to the second channel 12, the first valve hole 222 connects to the inner cavity 101 of the battery 10 through the first channel 11 and the docking nozzle 3. The second valve hole 223, the control hole 221, and the second air passage 225 connect to the accommodating space 13. The inner cavity 101 of the battery 10 can be drawn into a negative pressure state through the first valve hole 222, and the accommodating space 13 can be adjusted into a positive pressure state through the second valve hole 223 to complete the formation of the battery 10.

[0035] In this invention, the pressure in the inner cavity 101 of the battery 10 and the pressure in the accommodating space 13 where the battery 10 is located can be adjusted by the switching valve 2, which improves the integration of the integrated battery fixture. The integrated battery fixture has low manufacturing cost, occupies little space, and is easy to transport.

[0036] In one embodiment, such as Figure 1 and Figure 3As shown, the valve core 21 includes a valve stem 211 slidably inserted into the control hole 221. The valve stem 211 is provided with a sealing portion 212 that abuts against the inner wall of the control hole 221. It can be understood that the top of the valve stem 211 extends out of the control hole 221, and the sealing portion 212 includes, but is not limited to, a sealing ring 214 sleeved on the valve stem 211. The valve stem 211 is also provided with a sealing portion that abuts against the inner wall of the control hole 221, and the sealing portion is used to seal the control hole 221 from the external environment.

[0037] The valve seat 22 is also provided with a first air passage 224, a second air passage 225, and a third air passage 226, all of which are connected to the control hole 221. The first air passage 224 connects the first valve hole 222 and the first channel 11, the second air passage 225 connects to the second channel 12, and the third air passage 226 connects to the second valve hole 223. It can be understood that the first air passage 224, the second air passage 225, and the third air passage 226 are distributed sequentially along the axial direction of the control hole 221.

[0038] When the valve stem 211 drives the sealing part 212 to slide between the first air passage 224 and the second air passage 225, the first valve hole 222 connects to the first channel 11 through the first air passage 224, and the second valve hole 223 connects to the second channel 12 through the third air passage 226, the control hole 221, and the second air passage 225. It can be understood that when the sealing part 212 is located between the first air passage 224 and the second air passage 225, the first air passage 224 does not connect to the second air passage 225 through the control hole 221, so that the first air passage 224 and the second air passage 225 are in a non-connected state, and the third air passage 226 connects to the second air passage 225 through the control hole 221.

[0039] When the valve stem 211 drives the sealing part 212 to slide between the second air passage 225 and the third air passage 226, the first valve hole 222 connects to the first channel 11 through the first air passage 224. The first valve hole 222 also connects to the second channel 12 sequentially through the first channel 11, the control hole 221, and the second air passage 225. It can be understood that when the sealing part 212 is located between the second air passage 225 and the third air passage 226, the first air passage 224 connects to the second air passage 225 through the control hole 221, and the third air passage 226 is not connected to the second air passage 225.

[0040] In this embodiment, the state of the switching valve 2 can be controlled by moving the valve stem 211 in the control hole 221; the switching valve 2 has a simple structure, low manufacturing cost, and convenient control.

[0041] In one embodiment, such as Figure 1 As shown, the first air passage 224, the second air passage 225, and the third air passage 226 are connected to the control hole 221 through the first opening 227, the second opening 228, and the third opening 229, respectively, and the first opening 227, the second opening 228, and the third opening 229 are sequentially spaced along the axial direction of the control hole 221; it can be understood that the second opening 228 is located between the first opening 227 and the third opening 229.

[0042] When the sealing part 212 is located between the first opening 227 and the second opening 228, the first valve hole 222 is connected to the first channel 11 through the first air passage 224, and the second valve hole 223 is connected to the second channel 12 through the third air passage 226, the control hole 221, and the second air passage 225.

[0043] Specifically, when the sealing part 212 is located in the control hole 221 between the first opening 227 and the second opening 228, the first valve hole 222 sequentially connects to the inner cavity 101 of the battery 10 through the first channel 11 and the docking nozzle 3, and the second valve hole 223 sequentially connects to the accommodating space 13 through the third air passage 226, the control hole 221, and the second channel 12, while the first valve hole 222 does not connect to the second air passage 225 (the control hole 221 between the first air passage 224 and the second air passage 225 is blocked by the sealing part 212).

[0044] When the sealing part 212 is located between the second opening 228 and the third opening 229, when the valve stem 211 drives the sealing part 212 to slide between the second air passage 225 and the third air passage 226, the first valve hole 222 connects to the first channel 11 through the first air passage 224, and the first valve hole 222 also connects to the second channel 12 sequentially through the first channel 11, the control hole 221, and the second air passage 225.

[0045] Specifically, when the sealing part 212 is located in the control hole 221 between the second opening 228 and the third opening 229, the first valve hole 222 sequentially connects to the inner cavity 101 of the battery 10 through the first air passage 224 and the docking nozzle 3. The first valve hole 222 also sequentially connects to the accommodating space 13 through the first air passage 224, the control hole 221, and the second channel 12, while the third air passage 226 does not connect to the second air passage 225. In this embodiment, the switching valve 2 has a simple structure, low manufacturing cost, and convenient operation.

[0046] In one embodiment, such as Figure 1 As shown, the valve core 21 further includes a magnetic attractor 213 installed in the control hole 221 and used to attract the valve stem 211; the magnetic attraction of the magnetic attractor 213 to the valve stem 211 ensures that the sealing portion 212 is located in the control hole 221 between the second opening 228 and the third opening 229. It is understood that the magnetic attractor 213 includes, but is not limited to, magnets, etc., and the valve stem 211 is made of, but is not limited to, iron or steel materials; the magnetic attractor 213 is located below the valve stem 211 and always has a downward magnetic attraction on the valve stem 211. In this embodiment, when there is no pulling force, the magnetic attraction of the magnetic member 213 on the valve stem 211 causes the sealing part 212 to be located in the control hole 221 between the second opening 228 and the third opening 229. Thus, the first valve hole 222 not only connects to the inner cavity 101 of the battery 10, but also connects to the accommodating space 13, while the second valve hole 223 does not connect to the accommodating space 13. At this time, the switching valve 2 is in the normal state, which improves the convenience of the battery 10 fixture.

[0047] In one embodiment, such as Figure 3 As shown, the sealing part 212 is provided with an annular groove, and the valve core 21 also includes a sealing ring 214 sleeved in the annular groove. Understandably, the sealing ring 214 abuts against the inner wall of the control hole 221, thereby ensuring the sealing performance of the sealing part 212 in blocking the control hole 221.

[0048] In one embodiment, such as Figure 1 As shown, the first air passage 224 and the second air passage 225 are located on the same side of the control port 221, and the first air passage 224 and the third air passage 226 are located on opposite sides of the control port 221. For example, the first air passage 224 and the second air passage 225 are located on the right side of the control port 221, and the third air passage 226 is located on the left side of the control port 221. In this embodiment, the switching valve has a compact structure and occupies little space.

[0049] In one embodiment, such as Figure 3 As shown, the valve stem 211 is provided with a control part 215 located outside the control hole 221. Understandably, the control part 215 is located at the top of the valve stem 211, and an external robotic arm or similar device can use the control part 215 to move the valve stem 211 within the control hole 221.

[0050] In one embodiment, such as Figure 1 and Figure 2 As shown, the switching valve 2 further includes a first connector 23 inserted into the first valve hole 222 and a second connector 24 inserted into the second valve hole 223; the first connector 23 is used to control the opening and closing of the first valve hole 222, and the second connector 24 is used to control the opening and closing of the second valve hole 223. Understandably, when the external air source is not connected to the first connector 23, the first connector 23 is in a state of blocking the first valve hole 222; when the external air source is connected to the first connector 23, the external air source is connected to the first valve hole 222. Similarly, when the external air source is not connected to the second connector 24, the second connector 24 is in a state of blocking the second valve hole 223; when the external air source is connected to the second connector 24, the external air source is connected to the second valve hole 223.

[0051] In one embodiment, such as Figure 3 As shown, the integrated battery fixture also includes a formation probe 4 mounted on the housing 1, which is electrically connected to the battery 10 located in the receiving space 13. Understandably, two formation probes 4 are provided, connected to the positive and negative terminals of the battery 10 respectively; the formation probes 4 are connected to a power source, allowing the power source to charge and discharge the battery 10 through the formation probes 4, thereby completing the formation process of the battery 10. In this embodiment, the design of the formation probes 4 further improves the integration of the integrated battery fixture.

[0052] The above are merely embodiments of the integrated battery fixture of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
