Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a battery vibration testing device. Background Art

[0002] After the battery is produced, it is usually necessary to use battery vibration test equipment to perform performance tests such as shock resistance and heat dissipation. Battery vibration test equipment generally includes a vibration table for supporting the battery, a driving device for driving the vibration table to vibrate, a flow supply pipeline and a return pipeline, etc. The flow supply pipeline is used to connect to the flow inlet of the heat exchange flow channel of the cold plate in the battery to be tested to provide cooling medium to the battery to be tested. The return pipeline is used to connect to the flow outlet of the heat exchange flow channel of the cold plate in the battery to be tested to receive the cooling medium flowing out of the battery to be tested, so that the cooling medium can continuously flow in and out of the battery to be tested to dissipate heat from the battery to be tested.

[0003] In the battery vibration test equipment in the related art, the vibration table is likely to cause relative displacement of the supply pipeline and the return pipeline relative to the battery to be tested during the vibration process, thereby causing failure of the seal at the connection between the supply pipeline and the return pipeline and the battery to be tested, resulting in leakage of the cooling medium. Utility Model Content

[0004] In view of the above problems, the present application provides a battery vibration testing device, which can prevent the rigid supply tube and the rigid return tube from producing relative displacement with the battery to be tested during the vibration of the vibration table, and can ensure the sealing of the connection between the rigid supply tube and the rigid return tube and the battery to be tested as much as possible.

[0005] The present application embodiment provides a battery vibration test device, the battery vibration test device comprising:

[0006] A vibration table having a support surface for supporting a battery to be tested;

[0007] The substrate is arranged on one side of the supporting surface of the vibration table, and a surface of the substrate facing the supporting surface is in contact with the supporting surface;

[0008] A plurality of support members, the support members being arranged on a side of the substrate facing away from the vibration table; and

[0009] A rigid supply pipe and a rigid return pipe, wherein the flow outlet of the rigid supply pipe is used to be connected to the flow inlet of the heat exchange flow channel of the cold plate in the battery to be tested, and the flow inlet of the rigid return pipe is used to be connected to the flow outlet of the heat exchange flow channel of the cold plate in the battery to be tested;

[0010] Wherein, the rigid supply pipe is fixedly connected to at least one supporting member, and the rigid return pipe is fixedly connected to at least one supporting member.

[0011] When the above-mentioned battery vibration test equipment is actually used, the battery to be tested is fixedly connected to the vibration table. The substrate is arranged on one side of the supporting surface of the vibration table. The support member is arranged on the side of the substrate facing away from the vibration table, and the rigid supply pipe and the rigid return pipe are respectively fixedly connected to their corresponding support members. Therefore, the rigid supply pipe and the rigid return pipe can be effectively supported by the support member, and the rigid supply pipe and the rigid return pipe are relatively fixed to the substrate. Since both the supply pipe and the return pipe adopt rigid pipes, they can stably move synchronously with the support member and the substrate. Since the surface of the substrate facing the supporting surface is in contact with the supporting surface, the contact area between the substrate and the vibration table is large, so that the substrate is close to the vibration table, forming a structure similar to the foundation, and the rigid supply pipe and the rigid return pipe are firmly fixed to the vibration table. Thereby, the rigid supply tube and the rigid return tube can be vibrated at the same frequency as the substrate and the vibration table as much as possible, so that during the vibration of the vibration table, the rigid supply tube and the rigid return tube and the battery to be tested are not easily displaced relative to each other, and the sealing of the connection between the rigid supply tube and the rigid return tube and the battery to be tested can be guaranteed as much as possible.

[0012] In one embodiment, the rigid supply pipe and the rigid return pipe are respectively fixedly connected to one end of the corresponding support member away from the base plate, so that the height of the support member can be basically matched with the height position of the rigid supply pipe and the rigid return pipe.

[0013] In one embodiment, the rigid fluid supply tube corresponds to a plurality of support members, and the plurality of support members corresponding to the rigid fluid supply tube are sequentially spaced apart along the extension direction of the rigid fluid supply tube.

[0014] Multiple support members are used to support the rigid current supply tube at various positions in its extension direction, so that the rigid current supply tube can be more stably connected to the substrate through the multiple support members, and can then vibrate more reliably at the same frequency as the vibration table, further reducing the risk of relative displacement of the rigid current supply tube relative to the battery to be tested.

[0015] In one embodiment, the rigid return pipe corresponds to a plurality of support members, and the plurality of support members corresponding to the rigid return pipe are sequentially arranged at intervals along the extension direction of the rigid return pipe.

[0016] The rigid return tube is supported at various positions in its extension direction by multiple supporting members, so that the rigid return tube can be more stably connected to the substrate through the multiple supporting members, and can vibrate more reliably at the same frequency as the vibration table, further reducing the risk of relative displacement of the rigid return tube relative to the battery to be tested.

[0017] In one embodiment, the central axis of the rigid supply pipe and the central axis of the rigid return pipe are respectively parallel to a surface of the substrate facing away from the vibration table.

[0018] Since the central axis of the rigid fluid supply tube is parallel to the surface of the side of the substrate facing away from the vibration table, the height of each position of the rigid fluid supply tube along the extension direction is roughly the same as the height of the surface of the substrate. Therefore, it is convenient to fix the rigid fluid supply tube relative to the substrate through the support, and the rigid fluid supply tube can remain stable on the support, which is conducive to the rigid fluid supply tube, the substrate and the vibration table vibrating at the same frequency. When the number of support members corresponding to the rigid fluid supply tube is multiple, it is also convenient to fix the rigid fluid supply tube at each position along the extension direction with the corresponding support. Similarly, it is convenient to fix the rigid return pipe relative to the substrate through the support, and the rigid return pipe can remain stable on the support, which is conducive to the rigid return pipe, the substrate and the vibration table vibrating at the same frequency.

[0019] In one embodiment, the base plate is provided with a first fixing hole, and the vibration table is provided with a second fixing hole arranged corresponding to the first fixing hole;

[0020] The battery vibration testing device also includes a fixing piece, which is inserted into the first fixing hole and the second fixing hole to fix the base plate to the vibration table.

[0021] The fixing piece is inserted through the first fixing hole and the second fixing hole, so that the base plate and the vibration table can be reliably fixedly connected.

[0022] In one embodiment, the battery vibration testing device further includes a locking member; the rigid supply pipe and the rigid return pipe are respectively fixedly connected to their corresponding supporting members through at least one locking member.

[0023] The rigid supply pipe and the rigid return pipe are conveniently fixedly connected to their respective corresponding support members through the locking member.

[0024] In one embodiment, the locking member includes a hoop portion and connecting portions connected to both ends of the hoop portion, and the connecting portions are used to be fixedly connected to the support member;

[0025] The clamping part of the locking piece corresponding to the rigid flow supply pipe is used to clamp the rigid flow supply pipe; the clamping part of the locking piece corresponding to the rigid return pipe is used to clamp the rigid return pipe.

[0026] The structure of the locking member of this embodiment facilitates clamping of the rigid return pipe and the rigid supply pipe through the clamping hoop portion, and facilitates fixed connection of the locking member to the support member through the connecting portion, thereby facilitating secure connection of the rigid return pipe and the rigid supply pipe to the corresponding support member.

[0027] In one embodiment, the rigid fluid supply pipe includes a plurality of fluid supply pipe sections connected in sequence, and any two adjacent fluid supply pipe sections are arranged at an angle.

[0028] By making the rigid current supply tube include multiple current supply tube sections connected in sequence, and setting two adjacent current supply tube sections at an angle, the distribution of the rigid current supply tube can be made to extend in a zigzag manner, rather than being able to extend in a straight line along a specific direction. In this way, the length of the rigid current supply tube in a single straight direction can be reduced, so that the length of the rigid current supply tube with a longer total length can be met under conditions of limited space, thereby meeting the testing requirements of some larger batteries to be tested.

[0029] In one embodiment, the rigid return pipe includes a plurality of return pipe sections connected in sequence, and any two adjacent return pipe sections are arranged at an angle.

[0030] By making the rigid return pipe include multiple return pipe sections connected in sequence, and setting two adjacent return pipe sections at an angle, the distribution of the rigid return pipe can be made to extend in a zigzag manner instead of being able to extend in a straight line along a specific direction. In this way, the length of the rigid return pipe in a single direction can be reduced, so that the length of the rigid return pipe with a longer total length can be met under conditions of limited space, thereby meeting the testing requirements of some larger batteries to be tested.

[0031] In one embodiment, the rigid supply pipe and the rigid return pipe are spaced apart from each other, and the distance between the rigid supply pipe and the rigid return pipe remains constant along the extending direction of the rigid supply pipe and the extending direction of the rigid return pipe, so that the rigid return pipe and the rigid supply pipe are arranged compactly.

[0032] In one embodiment, the battery vibration testing equipment further comprises a flexible supply tube and a flexible return tube; the outlet of the flexible supply tube is used to connect with the inlet of the rigid supply tube; the inlet of the flexible return tube is used to connect with the outlet of the rigid return tube.

[0033] The battery vibration test equipment also includes a flexible supply pipe and a flexible return pipe. The flow outlet of the flexible supply pipe is used to connect with the flow inlet of the rigid supply pipe to deliver cooling medium to the rigid supply pipe, and the flow inlet of the flexible return pipe is used to connect with the flow outlet of the rigid return pipe to receive cooling medium from the rigid return pipe. The flow inlet of the flexible supply pipe is used to allow cooling medium to enter, and the flow outlet of the flexible return pipe is used to discharge cooling medium, so that the cooling medium circulates in the battery to be tested and the supply and return pipes.

[0034] In one embodiment, the battery vibration testing device further comprises a refrigeration mechanism, the outflow port of the refrigeration mechanism is connected to the inflow port of the flexible flow supply pipe, and the return port of the refrigeration mechanism is connected to the outflow port of the flexible return pipe.

[0035] Since the inlet of the flexible supply pipe and the outlet of the flexible return pipe are connected to the refrigeration mechanism, the flexible supply pipe can be flexibly deformed, so that the refrigeration mechanism can be fixed on the ground without vibration. In this way, the influence of the refrigeration mechanism on the vibration test of the battery to be tested can be minimized while satisfying the circulation of the cooling medium.

[0036] In one embodiment, the battery vibration test device further includes a joint structure; the outlet of the rigid supply pipe and the inlet of the rigid return pipe are respectively provided with a joint structure;

[0037] The joint structure includes a joint body, a flange and a fastener. The flange is sleeved and fixed on the joint body. The fastener is used to fix the flange to the battery to be tested.

[0038] In this embodiment, the flange is fixedly connected to the battery to be tested by fasteners, so that the joint structure can be reliably fixed to the battery to be tested, and the joint body and the battery to be tested are reliably sealed, which is beneficial to enhance the sealing of the connection between the rigid supply pipe, the rigid return pipe and the battery to be tested.

[0039] In one embodiment, the connector body is a male connector, and the outer peripheral surface of the connector body is provided with at least one annular groove;

[0040] The joint structure also includes a sealing ring, which is arranged in the corresponding annular groove.

[0041] In this embodiment, the connector body is set as a male connector, an annular groove is set on the outer peripheral surface of the connector body, and a sealing ring is set in the annular groove. When the connector body is plugged into the corresponding female connector on the battery to be tested, the sealing ring in the annular groove can improve the sealing of the connection between the connector body and the battery to be tested.

[0059] At present, from the perspective of market development, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0060] After the battery is produced, it is usually necessary to use battery vibration test equipment to perform performance tests such as shock resistance and heat dissipation. Battery vibration test equipment generally includes a vibration table for supporting the battery, a driving device for driving the vibration table to vibrate, a flow supply pipeline and a return pipeline, etc. The flow supply pipeline is used to connect to the flow inlet of the heat exchange flow channel of the cold plate in the battery to be tested to provide cooling medium to the battery to be tested. The return pipeline is used to connect to the flow outlet of the heat exchange flow channel of the cold plate in the battery to be tested to receive the cooling medium flowing out of the battery to be tested, so that the cooling medium can continuously flow in and out of the battery to be tested to dissipate heat from the battery to be tested.

[0061] In the battery vibration test equipment in the related art, the vibration table can easily cause the supply and return lines to be relatively displaced relative to the battery to be tested during the vibration process, thereby causing the seal failure at the connection between the supply and return lines and the battery to be tested, resulting in leakage of the cooling medium. The reason is that the battery vibration test equipment in the related art does not effectively support and fix the supply and return lines, and mainly relies on the battery to be tested to support the ends of the supply and return lines. In this way, during the vibration process of the vibration table, the battery to be tested and the vibration table can basically vibrate at the same frequency, while the vibration synchronization between the supply and return lines and the vibration table is poor, which can easily cause the supply and return lines to be relatively displaced relative to the battery to be tested, causing the seal failure at the connection between the supply and return lines and the battery to be tested.

[0062] Based on the above considerations, an embodiment of the present application provides a battery vibration test device, in which a support member is arranged on the side of the substrate facing away from the vibration table, and the rigid supply pipe and the rigid return pipe are effectively supported by the support member and the substrate, and the rigid supply pipe and the rigid return pipe are relatively fixed to the substrate. Since the surface of the substrate facing the supporting surface is in contact with the supporting surface, the contact area between the substrate and the vibration table is large, so that the substrate is close to the vibration table to form a structure similar to a foundation, and the rigid supply pipe and the rigid return pipe are firmly fixed to the vibration table. In this way, the rigid supply pipe and the rigid return pipe can be vibrated at the same frequency as the substrate and the vibration table as much as possible, and then during the vibration of the vibration table, the rigid supply pipe and the rigid return pipe are not easy to produce relative displacement with the battery to be tested, and the sealing of the connection between the rigid supply pipe and the rigid return pipe and the battery to be tested is guaranteed as much as possible.

[0063] Please refer to Figure 1 , Figure 1 The battery vibration test device provided in one embodiment of the present application includes a vibration table 100 , a base plate 200 , a plurality of support members 300 , a rigid supply pipe 400 and a rigid return pipe 500 .

[0064] The vibration table 100 has a support surface 101 for supporting the battery to be tested. It can be understood that the battery vibration test equipment also includes a driving device (not shown), which is used to drive the vibration table 100 to vibrate. The specific structure of the driving device can adopt the existing technology, which will not be described in detail.

[0065] The outlet of the rigid supply pipe 400 is used to connect with the inlet of the heat exchange channel of the cold plate in the battery to be tested, so as to deliver cooling medium to the battery to be tested, and the inlet of the rigid return pipe 500 is used to connect with the outlet of the heat exchange channel of the cold plate in the battery to be tested, so as to receive cooling medium from the battery to be tested. Thus, the cooling medium can continuously flow into and out of the heat exchange channel of the battery to be tested, so as to dissipate heat from the battery to be tested.

[0066] The substrate 200 is disposed on one side of the supporting surface 101 of the vibration table 100 , and a surface of the substrate 200 facing the supporting surface 101 is in contact with the supporting surface 101 .

[0067] Specifically, the substrate 200 is fixedly connected to the vibration table 100. The side surface of the substrate 200 facing the support surface 101 is the side surface of the substrate 200 facing the thickness direction. One end of the support member 300 is fixedly connected to the side of the substrate 200 facing away from the vibration table 100.

[0068] The rigid supply pipe 400 is fixedly connected to at least one supporting member 300 , and the rigid return pipe 500 is fixedly connected to at least one supporting member 300 .

[0069] Specifically, the rigid supply pipe 400 is disposed corresponding to at least one support member 300 and is fixedly connected to the corresponding support member 300. The rigid return pipe 500 is fixedly connected corresponding to at least one support member 300 and is fixedly connected to the corresponding support member 300.

[0070] When the battery to be tested is fixedly connected to the vibration table 100, the inlet and outlet of the heat exchange flow channel of the cold plate in the battery to be tested are at a certain height position higher than the vibration table 100. Therefore, when the rigid supply pipe 400 and the rigid return pipe 500 are respectively connected to the inlet and outlet of the heat exchange flow channel of the cold plate in the battery to be tested, the rigid supply pipe 400 and the rigid return pipe 500 are at a certain height position above the vibration table 100. In the embodiment of the present application, the support member 300 is arranged on the side of the substrate 200 facing away from the vibration table 100, and the rigid supply pipe 400 and the rigid return pipe 500 are respectively fixedly connected to their corresponding support members 300, so that the rigid supply pipe 400 and the rigid return pipe 500 can be reliably supported by the support member 300.

[0071] When the above-mentioned battery vibration test equipment is actually used, the battery to be tested is fixedly connected to the vibration table 100. The substrate 200 is arranged on one side of the support surface 101 of the vibration table 100. The support member 300 is arranged on the side of the substrate 200 facing away from the vibration table 100, and the rigid supply pipe 400 and the rigid return pipe 500 are respectively fixedly connected to their corresponding support members 300. Therefore, the rigid supply pipe 400 and the rigid return pipe 500 can be effectively supported by the support member 300, and the rigid supply pipe 400 and the rigid return pipe 500 are relatively fixed to the substrate 200. Since both the supply pipe and the return pipe are rigid pipes, they can stably move synchronously with the support member 300 and the substrate 200. Since the surface of the substrate 200 facing the supporting surface 101 is in contact with the supporting surface 101, the contact area between the substrate 200 and the vibration table 100 is relatively large, so that the substrate 200 is in close contact with the vibration table 100, forming a structure similar to a foundation, and the rigid supply pipe 400 and the rigid return pipe 500 are firmly fixed to the vibration table 100. In this way, the rigid supply pipe 400 and the rigid return pipe 500 can be vibrated at the same frequency as the substrate 200 and the vibration table 100 as much as possible, and further, during the vibration of the vibration table 100, the rigid supply pipe 400 and the rigid return pipe 500 are not likely to have relative displacement with the battery to be tested, and the sealing of the connection between the rigid supply pipe 400 and the rigid return pipe 500 and the battery to be tested can be guaranteed as much as possible.

[0072] Please refer to Figure 1 In one embodiment, the rigid supply pipe 400 and the rigid return pipe 500 are respectively fixedly connected to the ends of the corresponding support members 300 away from the substrate 200. Thus, the height of the support member 300 can be basically matched with the height positions of the rigid supply pipe 400 and the rigid return pipe 500.

[0073] In other embodiments, the rigid supply pipe 400 and the rigid return pipe 500 may also be connected to the middle of their corresponding support members 300 , respectively.

[0074] Please refer to Figure 1 and Figure 2 In some embodiments, the rigid fluid supply tube 400 corresponds to a plurality of support members 300 , and the plurality of support members 300 corresponding to the rigid fluid supply tube 400 are sequentially arranged at intervals along the extension direction of the rigid fluid supply tube 400 .

[0075] Exemplarily, the number of the plurality of support members 300 corresponding to the rigid supply pipe 400 is, for example, two, three, or more. The plurality of support members 300 are sequentially arranged at intervals along the extension direction of the rigid supply pipe 400, so that each position along the extension direction of the rigid supply pipe 400 is conveniently fixedly connected to the plurality of support members 300.

[0076] The rigid current supply tube 400 is supported at various positions in the extension direction by multiple support members 300, so that the rigid current supply tube 400 can be more stably connected to the substrate 200 through the multiple support members 300, and can then vibrate more reliably at the same frequency as the vibration table 100, further reducing the risk of relative displacement of the rigid current supply tube 400 relative to the battery to be tested.

[0077] In some other embodiments, the number of supporting members 300 corresponding to the rigid fluid supply tube 400 may also be one, that is, the rigid fluid supply tube 400 is fixedly connected to the substrate 200 via one supporting member 300 .

[0078] Please refer to Figure 1 and Figure 2 In some embodiments, the rigid return pipe 500 corresponds to a plurality of support members 300 , and the plurality of support members 300 corresponding to the rigid return pipe 500 are sequentially spaced apart along the extension direction of the rigid return pipe 500 .

[0079] Exemplarily, the number of the plurality of support members 300 corresponding to the rigid return pipe 500 is, for example, two, three, or more. The plurality of support members 300 are sequentially arranged at intervals along the extension direction of the rigid return pipe 500, so that each position along the extension direction of the rigid return pipe 500 is conveniently fixedly connected to the plurality of support members 300.

[0080] The rigid return tube 500 is supported at various positions in its extension direction by multiple support members 300, so that the rigid return tube 500 can be more stably connected to the substrate 200 through the multiple support members 300, and can thus vibrate more reliably at the same frequency as the vibration table 100, further reducing the risk of relative displacement of the rigid return tube 500 relative to the battery to be tested.

[0081] In some other embodiments, the number of supporting members 300 corresponding to the rigid return pipe 500 may also be one, that is, the rigid return pipe 500 is fixedly connected to the substrate 200 via one supporting member 300 .

[0082] The support member 300 corresponding to the rigid supply pipe 400 is defined as the first support member, and the support member 300 corresponding to the rigid return pipe 500 is defined as the second support member. Figure 1 and Figure 2 As shown, the plurality of first supporting members and the plurality of second supporting members are supporting members independent of each other.

[0083] Please refer to Figure 1 and Figure 2 In some embodiments, the central axis of the rigid supply pipe 400 and the central axis of the rigid return pipe 500 are respectively parallel to the surface of the substrate 200 facing away from the vibration table 100 .

[0084] Specifically, the extending direction of the rigid supply pipe 400 is parallel to the surface of the substrate 200 facing away from the vibration table 100 . The extending direction of the rigid return pipe 500 is parallel to the surface of the substrate 200 facing away from the vibration table 100 .

[0085] Since the central axis of the rigid fluid supply pipe 400 is parallel to the side surface of the substrate 200 facing away from the vibration table 100, the height of each position of the rigid fluid supply pipe 400 along the extension direction is roughly the same as the height of the surface of the substrate 200. Therefore, it is convenient to fix the rigid fluid supply pipe 400 relatively to the substrate 200 through the support 300, and the rigid fluid supply pipe 400 can remain stable on the support 300, which is conducive to the rigid fluid supply pipe 400, the substrate 200 and the vibration table 100 vibrating at the same frequency. When the number of support members 300 corresponding to the rigid fluid supply pipe 400 is multiple, it is also convenient to fix the rigid fluid supply pipe 400 at each position along the extension direction with the corresponding support member 300. Similarly, it is convenient to fix the rigid return pipe 500 relatively to the substrate 200 through the support 300, and the rigid return pipe 500 can remain stable on the support 300, which is conducive to the rigid return pipe 500, the substrate 200 and the vibration table 100 vibrating at the same frequency.

[0086] In other embodiments, the central axis of the rigid supply pipe 400 and the central axis of the rigid return pipe 500 may also be inclined to the side surface of the base plate 200 facing away from the vibration table 100 .

[0087] Please refer to Figure 1 and Figure 2 In some embodiments, the extension direction of the support member 300 is perpendicular to a side of the substrate 200 facing the first direction.

[0088] Since the first direction is the thickness direction of the substrate 200 , that is, the extension direction of the support member 300 is along the thickness direction of the substrate 200 , the support member 300 can support the rigid supply pipe 400 and the rigid return pipe 500 along the thickness direction of the substrate 200 .

[0089] When the battery vibration test equipment is actually performing a vibration test, the vibration direction of the vibration table 100 is mainly along the thickness direction of the substrate 200 and perpendicular to the thickness direction of the substrate 200. Therefore, in this embodiment, the rigid supply pipe 400 and the rigid return pipe 500 are supported along the thickness direction of the substrate 200 by the support member 300, so that during the vibration test, it can be more reliably ensured that the rigid supply pipe 400 and the rigid return pipe 500 vibrate at the same frequency as the vibration table 100.

[0090] In other embodiments, the extension direction of the support member 300 may also be inclined to the side of the substrate 200 facing the first direction.

[0091] Please refer to Figure 1 and Figure 2 In one embodiment, the substrate 200 is provided with a first fixing hole 201, and the vibration table 100 is provided with a second fixing hole (not shown) arranged corresponding to the first fixing hole 201. The battery vibration test device further includes a fixing member (not shown), which is passed through the first fixing hole 201 and the second fixing hole to fix the substrate 200 to the vibration table 100.

[0092] Specifically, the fixing member may be a bolt, a rivet or a fixing member of another structure.

[0093] The fixing piece is inserted into the first fixing hole 201 and the second fixing hole, so that the base plate 200 and the vibration table 100 can be reliably fixedly connected.

[0094] In other embodiments, the substrate 200 and the vibration table 100 may also be connected in other ways, such as welding, or clamping with a clamping tool.

[0095] Please refer to Figure 2 and Figure 3 , Figure 3 Shows Figure 2 In one embodiment, the battery vibration test device further includes a locking member 600, and the rigid supply pipe 400 and the rigid return pipe 500 are respectively fixedly connected to the corresponding support member 300 through at least one locking member 600.

[0096] Specifically, the rigid supply pipe 400 is fixedly connected to each corresponding support member 300 by at least one locking member 600. The rigid supply pipe 400 and each corresponding support member 300 may be fixed by one, two or more locking members 600. The rigid return pipe 500 and each corresponding support member 300 are fixedly connected by at least one locking member 600. The rigid return pipe 500 and each corresponding support member 300 may be fixed by one, two or more locking members 600.

[0097] The locking member 600 facilitates the fixed connection between the rigid supply pipe 400 and the rigid return pipe 500 and their corresponding supporting members 300 .

[0098] Please combine Figure 2 and Figure 3 In one embodiment, the locking member 600 includes a hoop portion 610 and a connecting portion 620 connected to both ends of the hoop portion 610. The connecting portion 620 is fixedly connected to the support member 300. The hoop portion 610 of the locking member 600 corresponding to the rigid supply pipe 400 is used to hold the rigid supply pipe 400 tightly. The hoop portion 610 of the locking member 600 corresponding to the rigid return pipe 500 is used to hold the rigid return pipe 500 tightly.

[0099] Specifically, the hoop portion 610 and the connecting portions 620 at both ends thereof may be an integrally formed structure, or may be a split structure and connected (e.g., welded). By fixedly connecting the connecting portion 620 to the support member 300, the locking member 600 may be fixedly connected to the support member 300 as a whole. The connecting portion 620 and the support member 300 may be fixed by bolt connection, rivet connection, or the like.

[0100] like Figure 3 As shown, exemplarily, the hoop portion 610 is configured with a clamping cavity 611, and the opening of the clamping cavity 611 faces the support member 300. The hoop portion 610 of the locking member 600 on the support member 300 corresponding to the rigid return pipe 500 is arranged around a part of the outer circumference of the rigid return pipe 500, so that the rigid return pipe 500 is located in the clamping cavity 611 and is limited by the support member 300 at the opening of the clamping cavity 611, so that the hoop portion 610 and the support member 300 clamp the rigid return pipe 500 together. Similarly, the hoop portion 610 of the locking member 600 on the support member 300 corresponding to the rigid supply pipe 400 and the support member 300 clamp the rigid supply pipe 400 together.

[0101] The structure of the locking member 600 of this embodiment facilitates clamping of the rigid return pipe 500 and the rigid supply pipe 400 through the clamping hoop portion 610, and facilitates fixed connection of the locking member 600 and the support member 300 through the connecting portion 620, thereby facilitating secure connection of the rigid return pipe 500 and the rigid supply pipe 400 to the corresponding support member 300.

[0102] In other embodiments, the locking member may also be other types of locking member structures, for example, the locking member includes a first clamping hoop portion and a second clamping hoop portion, the first clamping hoop portion and the second clamping hoop portion are opposite to each other and fixedly connected, thereby jointly defining a clamping cavity. The rigid return pipe and the rigid supply pipe can be clamped in the clamping cavities of the respective corresponding locking members. Both ends of the first clamping hoop portion and the second clamping hoop portion are respectively provided with connection portions for fixing to the support member.

[0103] Please refer to Figure 2 and Figure 3 In some embodiments, the rigid supply pipe 400 and the rigid return pipe 500 are respectively located on the side of the corresponding support member 300 away from the substrate 200, and the locking member 600 is opposite to the side of the support member 300.

[0104] exist Figure 2 and Figure 3 In the embodiment shown, the support member 300 is a channel steel structure, and the cross section of the channel steel is a groove structure. By placing the locking member 600 opposite to and connecting the side of the support member 300, it is convenient to fix the locking member 600 to the support member 300.

[0105] In other embodiments, the support member 300 may also be a prism (such as a triangular prism, a quadrangular prism) or other shapes. The rigid supply pipe 400 and the rigid return pipe 500 and the locking member 600 may also be located on one side of the end surface of the corresponding support member 300 away from the substrate 200 .

[0106] Please refer to Figure 2 and Figure 3 In some embodiments, the support member 300 corresponding to the rigid supply pipe 400 is located on the side of the rigid supply pipe 400 facing away from the rigid return pipe 500. The support member 300 corresponding to the rigid return pipe 500 is located on the side of the rigid return pipe 500 facing away from the rigid supply pipe 400.

[0107] In other embodiments, the support member 300 corresponding to the rigid supply pipe 400 may also be located on a side of the rigid supply pipe 400 close to the rigid return pipe 500. The support member 300 corresponding to the rigid return pipe 500 may also be located on a side of the rigid return pipe 500 close to the rigid supply pipe 400.

[0108] In some embodiments, the rigid fluid supply pipe 400 includes a plurality of fluid supply pipe units connected in sequence.

[0109] Specifically, adjacent flow supply pipe units may be detachably connected or non-detachably connected.

[0110] A rigid fluid supply pipe 400 is formed by splicing a plurality of fluid supply pipe units connected in sequence, which allows flexible selection of rigid fluid supply pipes 400 of required specifications for splicing according to usage requirements, and allows flexible splicing lengths, and the rigid fluid supply pipes 400 can also be spliced ​​in different directions, thereby improving usage flexibility.

[0111] The rigid current supply tube 400 of the embodiment of the present application can vibrate at the same frequency as the substrate 200 and the vibration table 100. Therefore, not only the relative displacement between the rigid current supply tube 400 and the battery to be tested can be reduced, but also the relative displacement between adjacent current supply tube units can be reduced, thereby enhancing the sealing of the connection between adjacent current supply tube units.

[0112] In some embodiments, the rigid return pipe 500 includes a plurality of return pipe units connected in sequence.

[0113] Specifically, adjacent return pipe units may be detachably connected or non-detachably connected.

[0114] A rigid return pipe 500 is formed by splicing a plurality of return pipe units connected in sequence, so that the rigid return pipe 500 of required specifications can be flexibly selected for splicing according to usage requirements, and the length of the splicing can be flexibly adjusted. The rigid return pipe 500 can also be spliced ​​in different directions, thereby improving the flexibility of use.

[0115] The rigid return pipe 500 of the embodiment of the present application can vibrate at the same frequency as the substrate 200 and the vibration table 100. Therefore, not only the relative displacement between the rigid return pipe 500 and the battery to be tested can be reduced, but also the relative displacement between adjacent return pipe units can be reduced, thereby enhancing the sealing of the connection between adjacent return pipe units.

[0116] Please refer to Figure 2 In some embodiments, the rigid fluid supply pipe 400 includes a plurality of fluid supply pipe sections connected in sequence, and any two adjacent fluid supply pipe sections are arranged at an angle.

[0117] The included angle between two adjacent flow supply pipe sections may be a right angle, an acute angle or an obtuse angle.

[0118] For example, Figure 2 As shown, there are two sections of the current supply pipe, namely the first current supply pipe section 410 and the second current supply pipe section 420. One end of the first current supply pipe section 410 is connected to one end of the second current supply pipe section 420, and the first current supply pipe section 410 and the second current supply pipe section 420 are arranged at an angle. One end of the second current supply pipe section 420 away from the first current supply pipe section 410 is the inlet of the rigid current supply pipe 400, which is used to pass the cooling medium. In this way, the cooling medium can enter the battery to be tested through the second current supply pipe section 420 and the first current supply pipe section 410 in sequence, thereby passing the cooling medium into the battery to be tested.

[0119] By configuring the rigid current supply tube 400 to include a plurality of current supply tube sections connected in sequence, and setting two adjacent current supply tube sections at an angle, the distribution of the rigid current supply tube 400 can be made to extend in a zigzag manner rather than being able to extend in a straight line in a specific direction. In this way, the length of the rigid current supply tube 400 in a single straight direction can be reduced, so that the length of the rigid current supply tube 400 with a longer total length can be met under conditions of limited space, thereby meeting the testing requirements of some larger batteries to be tested.

[0120] Each flow supply pipe section of the rigid flow supply pipe 400 may include one flow supply pipe unit or a plurality of flow supply pipe units connected in sequence.

[0121] In other embodiments, the rigid fluid supply pipe 400 includes three or more fluid supply pipe sections connected in sequence, and any two adjacent fluid supply pipe sections are arranged at an angle.

[0122] For some other smaller batteries to be tested, a rigid current supply tube extending in a single straight direction may also be selected.

[0123] Please refer to Figure 2 In some embodiments, the rigid return pipe 500 includes a plurality of return pipe segments connected in sequence, and any two adjacent return pipe segments are arranged at an angle.

[0124] The included angle between two adjacent return pipe sections may be a right angle, an acute angle or an obtuse angle.

[0125] For example, Figure 2 As shown, there are two return pipe sections, namely, a first return pipe section 510 and a second return pipe section 520. One end of the first return pipe section 510 is connected to one end of the second return pipe section 520, and the first return pipe section 510 and the second return pipe section 520 are arranged at an angle. Specifically, one end of the first return pipe section 510 away from the second return pipe section 520 is the inlet of the rigid return pipe 500. In this way, the cooling medium circulating out of the battery to be tested can be discharged through the first return pipe section 510 and the second return pipe section 520 in sequence.

[0126] By making the rigid return pipe 500 include multiple return pipe sections connected in sequence, and setting two adjacent return pipe sections at an angle, the distribution of the rigid return pipe 500 can be extended in a zigzag manner instead of being able to extend in a straight line along a specific direction. In this way, the length of the rigid return pipe 500 in a single direction can be reduced, so that the length of the rigid return pipe 500 with a longer total length can be met under conditions of limited space, thereby meeting the testing requirements of some larger batteries to be tested.

[0127] Each return pipe section of the rigid return pipe 500 may include one return pipe unit or a plurality of return pipe units connected in sequence.

[0128] In other embodiments, the rigid return pipe 500 includes three or more return pipe sections connected in sequence, and any two adjacent return pipe sections are arranged at an angle.

[0129] For some other smaller batteries to be tested, a rigid return pipe extending in a single straight direction may also be selected.

[0130] In some embodiments, the rigid supply pipe 400 and the rigid return pipe 500 are spaced apart from each other, and the distance between the rigid supply pipe 400 and the rigid return pipe 500 remains unchanged along the extension direction of the rigid supply pipe 400 and the extension direction of the rigid return pipe 500. That is, the rigid return pipe 500 and the rigid supply pipe 400 are parallel and spaced apart, so that the rigid return pipe 500 and the rigid supply pipe 400 are compactly arranged.

[0131] In one embodiment, the battery vibration test equipment further includes a flexible supply pipe and a flexible return pipe, the flow outlet of the flexible supply pipe is used to connect with the flow inlet of the rigid supply pipe 400 to deliver cooling medium to the rigid supply pipe 400, and the flow inlet of the flexible return pipe is used to connect with the flow outlet of the rigid return pipe 500 to receive cooling medium from the rigid return pipe 500. The flow inlet of the flexible supply pipe is used to allow the cooling medium to enter, and the flow outlet of the flexible return pipe is used to discharge the cooling medium, so that the cooling medium circulates in the battery to be tested and the supply and return pipes.

[0132] Optionally, the battery vibration test equipment further includes a refrigeration mechanism. In this embodiment, the outlet of the flexible supply pipe is connected to the inlet of the rigid supply pipe 400, the inlet of the flexible return pipe is connected to the outlet of the rigid return pipe 500, the outlet of the refrigeration mechanism is connected to the inlet of the flexible supply pipe, and the return port of the refrigeration mechanism is connected to the outlet of the flexible return pipe, so that the cooling medium can circulate among the battery to be tested, the flexible supply pipe, the rigid supply pipe, the rigid return pipe, the flexible return pipe and the refrigeration mechanism.

[0133] During the vibration test of the battery vibration test equipment, the battery to be tested, the rigid supply pipe 400 and the rigid return pipe 500 vibrate together with the vibration table 100. The inlet of the flexible return pipe and the outlet of the rigid return pipe 500 vibrate together, and the outlet of the flexible supply pipe and the inlet of the rigid supply pipe 400 vibrate together.

[0134] Since the inlet of the flexible supply pipe and the outlet of the flexible return pipe are connected to the refrigeration mechanism, the flexible supply pipe can be flexibly deformed, so that the refrigeration mechanism can be fixed on the ground without vibration. In this way, the influence of the refrigeration mechanism on the vibration test of the battery to be tested can be minimized while satisfying the circulation of the cooling medium.

[0135] In other embodiments, the battery vibration test equipment may not include a refrigeration mechanism. For example, the inlet of the flexible supply pipe and the outlet of the flexible return pipe may be connected to the outlet and return port of the cooling tower, respectively, so that the cooling medium can be output to the flexible supply pipe through the cooling tower, and the cooling medium can be received from the flexible return pipe. In this way, it can be achieved that the cooling medium can circulate in the battery to be tested and the supply and return pipes, and the influence of the cooling tower on the vibration test of the battery to be tested can be minimized.

[0136] Please combine Figure 1 , Figure 2 and Figure 4 , Figure 4 A schematic diagram of the joint structure of some embodiments of the present application is shown. In some embodiments, the battery vibration test equipment also includes a joint structure 700. The outlet of the rigid supply pipe 400 and the inlet of the rigid return pipe 500 are respectively provided with a joint structure 700. The joint structure 700 at the outlet of the rigid supply pipe 400 is used to connect with the inlet of the heat exchange flow channel of the cold plate in the battery to be tested. The joint structure 700 at the inlet of the rigid return pipe 500 is used to connect with the outlet of the heat exchange flow channel of the cold plate in the battery to be tested.

[0137] The outlet of the rigid supply pipe 400 and the inlet of the rigid return pipe 500 are conveniently connected to the inlet and outlet of the heat exchange flow channel of the cold plate in the battery to be tested through the joint structure 700.

[0138] Please refer to Figure 4 In some embodiments, the joint structure 700 includes a joint body 710, a flange 720 and a fastener 730. The flange 720 is mounted on and fixed to the joint body 710. The fastener 730 is used to fix the flange 720 to the battery to be tested.

[0139] The flange 720 and the joint body 710 may be integrally formed or separately formed and connected.

[0140] Exemplarily, the fastener 730 is a connecting member such as a bolt. The flange 720 is provided with a connecting hole 721, and the fastener 730 passes through the connecting hole on the flange 720 and penetrates into the battery to be tested so as to fix the flange 720 with the battery to be tested.

[0141] The joint body 710 of the joint structure 700 at the outlet of the rigid supply pipe 400 is used to connect with the inlet of the heat exchange channel of the cold plate in the battery to be tested, so that the cooling medium from the rigid supply pipe 400 can be input into the battery to be tested through the joint body 710. The joint body 710 of the joint structure 700 at the inlet of the rigid return pipe 500 is used to connect with the outlet of the heat exchange channel of the cold plate in the battery to be tested, so that the cooling medium flowing out of the battery to be tested can be discharged to the rigid return pipe 500 through the joint body 710.

[0142] In this embodiment, the flange 720 is fixedly connected to the battery to be tested by the fastener 730, so that the joint structure 700 can be reliably fixed to the battery to be tested, and then the joint body 710 and the battery to be tested are reliably sealed, which is beneficial to enhance the sealing of the connection between the rigid supply pipe 400, the rigid return pipe 500 and the battery to be tested.

[0143] Please refer to Figure 4 In some embodiments, the connector body 710 is a male connector. Therefore, when the connector body 710 is connected to the battery to be tested, it is inserted into the corresponding female connector on the battery to be tested.

[0144] The outer circumference of the joint body 710 is provided with at least one annular groove 711 . The joint structure 700 further includes a sealing ring, which is arranged in the corresponding annular groove 711 .

[0145] Specifically, the annular groove is a mounting groove of the sealing ring, and is used for positioning the corresponding sealing ring.

[0146] In this embodiment, the connector body 710 is set as a male connector, an annular groove 711 is set on the outer peripheral surface of the connector body 710, and a sealing ring is set in the annular groove. When the connector body 710 is plugged into the corresponding female connector on the battery to be tested, the sealing ring in the annular groove 711 can improve the sealing performance of the connection between the connector body 710 and the battery to be tested.

[0147] It can be understood that the inlet and outlet of the heat exchange flow channel of the cold plate in the battery to be tested are respectively provided with female connectors. The connector body 710 of the connector structure 700 at the outlet of the rigid supply pipe 400 is plugged into the female connector of the inlet of the heat exchange flow channel of the cold plate in the battery to be tested, and the connector body 710 of the connector structure 700 at the inlet of the rigid return pipe 500 is plugged into the female connector of the outlet of the heat exchange flow channel of the cold plate in the battery to be tested.

[0148] In some embodiments, the outer peripheral surface of the joint body 710 is provided with a plurality of annular grooves 711 spaced apart in the axial direction. The sealing rings are provided corresponding to the annular grooves 711. Each sealing ring is provided in the corresponding annular groove 711.

[0149] Specifically, the number of the annular grooves 711 on the joint body 710 is at least two, and may be two, three, etc. A sealing ring is disposed in each annular groove 711 .

[0150] When the connector body 710 is plugged into the corresponding female connector on the battery to be tested, the multiple sealing rings in the multiple annular grooves 711 can better improve the sealing performance of the connection between the connector body 710 and the battery to be tested.

[0151] In other embodiments, an annular groove may be provided on the outer peripheral surface of the joint body, and a sealing ring may be installed in the annular groove. In this case, a corresponding sealing ring is arranged in one annular groove.

[0152] Please refer to Figure 5 , Figure 5 A schematic diagram of the structure of the adapter of some embodiments of the present application is shown. In some embodiments, the battery vibration test equipment also includes an adapter 800, which is used to be fixedly connected to the battery to be tested. A supply channel 801 and a return channel 802 are provided on the adapter 800. The inlet of the supply channel 801 is used to connect with the joint structure 700 at the outlet of the rigid supply pipe 400, and the outlet of the supply channel 801 is used to connect with the inlet of the heat exchange flow channel of the cold plate in the battery to be tested. The inlet of the return channel 802 is used to connect with the outlet of the heat exchange flow channel of the cold plate in the battery to be tested, and the outlet of the return channel 802 is used to connect with the joint structure 700 at the inlet of the rigid return pipe 500.

[0153] Battery vibration test equipment generally needs to test batteries of various specifications. Sometimes, the joint structure 700 of the outlet of the rigid supply pipe 400 does not match the inlet structure of the heat exchange flow channel of the cold plate in the battery under test, or the joint structure 700 of the inlet of the rigid return pipe 500 does not match the outlet structure of the heat exchange flow channel of the cold plate in the battery under test.

[0154] In this embodiment, the battery vibration test equipment is equipped with an adapter 800, and the inlet of the supply channel 801 on the adapter 800 can be adapted to the joint structure 700 at the outlet of the rigid supply pipe 400, and the outlet of the return channel 802 on the adapter 800 can be adapted to the joint structure 700 at the inlet of the rigid return pipe 500. The outlet of the supply channel 801 on the adapter 800 can be adapted to the inlet of the heat exchange channel of the cold plate in the battery to be tested, and the inlet of the return channel 802 can be adapted to the outlet of the heat exchange channel of the cold plate in the battery to be tested, so that the joint structure 700 at the outlet of the rigid supply pipe 400 and the joint structure 700 at the inlet of the rigid return pipe 500 can be connected to the battery to be tested through the adapter 800. In this way, even if the joint structure 700 of the outlet of the rigid supply pipe 400 does not match the inlet structure of the heat exchange channel of the cold plate in the battery to be tested, or the joint structure 700 of the inlet of the rigid return pipe 500 does not match the outlet structure of the heat exchange channel of the cold plate in the battery to be tested, there is no need to replace the entire rigid supply pipe 400 or the rigid return pipe 500.

[0155] Furthermore, the adapter 800 is provided with a first matching hole 803 and a second matching hole 804. When the joint structure 700 is connected to the battery to be tested through the adapter 800, the joint structure 700 and the adapter 800 are fixedly connected.

[0156] Specifically, the fastener 730 of the joint structure 700 at the outlet of the rigid supply pipe 400 can be passed through the connection hole 721 on the flange 720 and inserted into the first matching hole 803, so that the joint structure 700 is fixedly connected to the adapter 800. The fastener 730 of the joint structure 700 at the inlet of the rigid return pipe 500 can be passed through the connection hole 721 on the flange 720 and inserted into the second matching hole 804, so that the joint structure 700 is fixedly connected to the adapter 800.

[0157] When the joint body 710 of the joint structure 700 is a male connector, it is plugged into the corresponding female connector on the adapter 800. Specifically, the joint body 710 of the joint structure 700 at the outlet of the rigid supply pipe 400 is plugged into the female connector structure at the inlet of the supply channel on the adapter 800. The joint body 710 of the joint structure 700 at the inlet of the rigid return pipe is plugged into the female connector structure at the outlet of the return channel on the adapter 800.

[0158] In one embodiment, there are multiple adapters 800, and the structures of the inlet ports of the flow supply channels 801 of the multiple adapters 800 are the same. The structures of the outlet ports of the return channels 802 of the multiple adapters 800 are the same. Thus, the inlet ports of the flow supply channels 801 of the multiple adapters 800 can be adapted to the joint structures of the same specification, and the outlet ports of the return channels 802 of the multiple adapters 800 can be adapted to the joint structures of the same specification.

[0159] The structures of the outflow ports of the flow supply channels 801 of the multiple adapters 800 are different from each other, so that the outflow ports of the flow supply channels 801 of the multiple adapters 800 can respectively adapt to the inflow ports of the heat exchange flow channels of the cold plates of the batteries to be tested with different structures. The structures of the inflow ports of the return channels 802 of the multiple adapters 800 are different from each other, so that the outflow ports of the return channels 802 of the multiple adapters 800 can respectively adapt to the inflow ports of the heat exchange flow channels of the cold plates of the batteries to be tested with different structures.

[0160] In this embodiment, multiple adapters 800 are provided, and the inlet of the flow supply channel 801 of the multiple adapters 800 can be adapted to the joint structure of the same specification, and the outlet of the return channel 802 of the multiple adapters 800 can be adapted to the joint structure of the same specification. The outlets of the flow supply channels 801 of the multiple adapters 800 can be adapted to the inlet of the heat exchange flow channel of the cold plate of the battery to be tested with various different structures, and the outlets of the return channel 802 of the multiple adapters 800 can be adapted to the outlet of the heat exchange flow channel of the cold plate of the battery to be tested with various different structures. In this way, only multiple adapters 800 need to be prepared, and the joint structure 700 of the inlet of the rigid return pipe 500 and the joint structure 700 of the outlet of the rigid flow supply pipe 400 can be conveniently adapted to the batteries to be tested with different specifications, so that there is no need to replace the flow supply pipeline and the return pipeline every time the batteries to be tested with different specifications are tested, thereby simplifying the testing process.
