[0045] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0046] In related technologies, the various components of a DC-DC converter are typically assembled piecemeal on the frame 5 of the probe assembly. However, since each component usually requires wiring harnesses to achieve electrical connections with external devices, this results in a large number of wiring harnesses extending from the probe assembly, which severely affects the ease of maintenance of the probe assembly.

[0047] In the power supply chassis 1 provided in this application embodiment, by integrating the circuit board 102, temperature acquisition terminal 103 and positive and negative terminals 104 on the power supply chassis 1, the wiring harness led out from the probe assembly is effectively reduced, and the convenience of probe assembly maintenance is improved.

[0048] Reference Figure 1 and Figure 2 This application provides a power supply chassis 1, which includes:

[0049] Housing 101, with a mounting cavity 1010 formed inside the housing 101;

[0050] Circuit board 102 is disposed in mounting cavity 1010;

[0051] Temperature acquisition terminal 103 and positive and negative terminals 104 are provided. One end of temperature acquisition terminal 103 is electrically connected to circuit board 102, and the other end of temperature acquisition terminal 103 extends through housing 101 to be exposed outside housing 101. One end of positive and negative terminals 104 is electrically connected to circuit board 102, and the other end of positive and negative terminals 104 extends through housing 101 to be exposed outside housing 101.

[0052] In the above embodiments, the power supply chassis 1, i.e. the chassis-type DC-DC power module, is formed by integrating all the components of the DC-DC, such as the circuit board 102, temperature acquisition terminal 103, and positive and negative terminals 104, into the housing 101 to form a chassis-type modular structure. This realizes the product design of the DC-DC. Compared with the method in related technologies where the components of the DC-DC are scattered and assembled on the frame 5 of the probe assembly, the structure is more regular and the assembly and maintenance are more convenient.

[0053] See Figure 1 and Figure 2 The housing 101 serves as a protective structure for the power supply chassis 1, providing a closed and stable installation space for components such as the circuit board 102, temperature acquisition terminal 103, and positive and negative terminals 104. This prevents internal components from being damaged by impacts and thus improves the overall reliability and ease of maintenance of the power supply chassis 1.

[0054] In the above embodiments, the circuit board 102 may integrate a temperature control component, so that the temperature acquisition terminal 103 can be directly electrically connected to the circuit board 102 and the external circuit to realize real-time temperature acquisition of the power supply chassis 1, ensure the accuracy and response speed of temperature detection of the power supply chassis 1, and facilitate temperature control of the power supply chassis 1, thereby greatly reducing the temperature wiring harness.

[0055] In the above embodiments, the circuit board 102 may also integrate a channel adapter component, which facilitates the rapid connection of the positive and negative terminals 104 to the circuit board 102 and the external probe structure, realizes stable transmission between the power supply channel and the control channel, improves assembly efficiency and connection reliability, and also significantly reduces the channel wiring harness.

[0056] Therefore, by placing the circuit board 102, which integrates temperature control components and channel adapter components, in the mounting cavity 1010, this embodiment of the application eliminates the need for additional independent temperature control boxes and channel adapter boards, simplifying the overall circuit layout of the power supply chassis 1, reducing the number of wiring harnesses and connection nodes, and lowering the failure risk and maintenance difficulty of the power supply chassis 1.

[0057] In some embodiments, see Figures 1 to 3 The other end of the temperature acquisition terminal 103 and the other end of the positive and negative terminals 104 extend through the housing 101 to be exposed outside the housing 101, so that temperature detection and probe 2 can be achieved without disassembling the housing 101, which greatly reduces the maintenance and testing operation cost of the power supply chassis 1.

[0058] In one embodiment, the circuit board 102 includes a power board 1021 and a terminal board 1022, which are electrically connected; wherein, the temperature acquisition terminal 103 is electrically connected to the terminal board 1022, and the positive and negative terminals 104 are electrically connected to the power board 1021.

[0059] In the above embodiments, the circuit board 102 adopts a split design of power board 1021 and terminal board 1022. The two are electrically connected through board connectors (such as pin headers and board-to-board connectors). That is, the circuit board 102 forms a layered electrical structure, which effectively simplifies the circuit wiring in the power supply chassis 1 and reduces the failure risk and maintenance difficulty of the power supply chassis 1.

[0060] See Figure 1 and Figure 2 Temperature acquisition terminal 103 serves as the temperature signal acquisition interface for power supply chassis 1, and is directly electrically connected to terminal board 1022 (terminal board 1022 is an integrated board that integrates temperature control components). This effectively isolates electromagnetic interference from the power circuit and improves the accuracy and reliability of temperature detection in power supply chassis 1. Positive and negative terminals 104 serve as the power input / output interface for power supply chassis 1, and are directly electrically connected to power board 1021 (power board 1021 integrates channel adapter components). This can carry the high-current power circuits of various DCDC components and meet the high-current transmission requirements of power supply chassis 1.

[0061] In some embodiments, see Figure 1 and Figure 2 The positive and negative terminals 104 are located in the lower part of the housing 101. The positive and negative terminals 104 include multiple positive and negative terminals to facilitate quick docking between the power supply chassis 1 and the probes 2 of the probe assembly.

[0062] In some embodiments, see Figure 1 and Figure 2 The power supply chassis 1 also includes fasteners 108. Multiple fasteners 108 are provided. The multiple fasteners 108 can respectively connect the power board 1021 and the inner wall of the housing 101 along the length direction, and connect the terminal board 1022 and the inner wall of the housing 101 along the width direction, so as to ensure the stability and reliability of the power board 1021 and the terminal board 1022 during use.

[0063] In one embodiment, the power supply chassis 1 further includes a voltage sampling terminal 105, one end of which is electrically connected to the terminal block 1022, and the other end of which extends through the housing 101 to protrude outside the housing 101.

[0064] In the above embodiments, the voltage sampling terminal 105 can be directly electrically connected to the terminal board 1022 and the external circuit to realize real-time voltage acquisition of the power supply chassis 1, ensuring the accuracy and response speed of voltage detection of the power supply chassis 1, and also facilitating voltage control of the power supply chassis 1, greatly reducing the voltage wiring harness.

[0065] See Figure 1 and Figure 2 The voltage sampling terminal 105 serves as the voltage sampling interface of the power supply chassis 1 and is directly electrically connected to the terminal block 1022. This enables physical isolation between the power circuit and the sampling circuit, avoiding interference from high-current power signals to weak voltage sampling signals and improving the accuracy and stability of voltage sampling.

[0066] In some embodiments, see Figures 1 to 3 The other end of the voltage sampling terminal 105 extends through the housing 101 to protrude outside the housing 101, so that voltage detection can be achieved without disassembling the housing 101, which greatly reduces the maintenance and testing costs of the power supply chassis 1.

[0067] In some embodiments, see Figure 1 and Figure 2 Temperature acquisition terminal 103 and voltage sampling terminal 105 are both electrically connected to terminal board 1022, which facilitates the unified layout of terminals in power supply chassis 1, optimizes the wiring space inside power supply chassis 1, and further reduces the number of wire harnesses.

[0068] In some embodiments, see Figure 3 The housing 101 also includes multiple protective plates 1013, which can correspond to the temperature acquisition terminal 103 and the voltage sampling terminal 105 respectively, so as to protect the temperature acquisition terminal 103 and the voltage sampling terminal 105 when they are not in use, thereby extending the service life of the temperature acquisition terminal 103 and the voltage sampling terminal 105.

[0069] In one embodiment, the power supply chassis 1 further includes a fan 106, which is disposed in the mounting cavity 1010 and is electrically connected to the circuit board 102.

[0070] In the above embodiments, the power supply chassis 1 may also integrate a fan 106. The fan 106 is located in the upper area of ​​the mounting cavity 1010, and the housing 101 has a ventilation port 1012 corresponding to the fan 106, so as to timely exhaust the heat generated by the power supply chassis 1 during operation to the outside of the housing 101, achieve efficient heat dissipation, ensure the temperature stability of the power supply chassis 1 during continuous operation, and avoid performance degradation or damage due to overheating.

[0071] In the above embodiments, the circuit board 102 may integrate a fan 106 control component, which facilitates the realization of self-temperature control of the power supply chassis 1 through the electrical connection between the fan 106 and the circuit board, ensuring efficient heat dissipation of the power supply chassis 1. At the same time, there is no need to configure a separate fan 106 control board, which further simplifies the structure of the power supply chassis 1, reduces the number of wiring harnesses and connection nodes, and improves the convenience of maintenance.

[0072] In some embodiments, see Figure 1 and Figure 2 Fastener 108 can also connect the fan 106 and the housing 101 along the inner wall in the height direction, ensuring the stability and reliability of the fan 106 during use.

[0073] In one embodiment, the power supply chassis 1 further includes a first copper busbar 107, which is disposed in the mounting cavity 1010 and is arranged along the length direction of the housing 101; wherein, the housing 101 is provided with through holes 1011 at both ends of the first copper busbar 107.

[0074] In the above embodiments, the length direction can be... Figure 3 In the lateral direction, the first copper busbar 107 can extend in the length direction of the housing 101 to facilitate electrical connection of various components in the power supply chassis 1, reduce the current transmission path, and reduce the on-resistance and heat loss of the power supply chassis 1.

[0075] See Figure 1 and Figure 2 The housing 101 is also provided with through holes 1011 at both ends of the first copper busbar 107, so as to realize the series connection between multiple power supply chassis 1 or the electrical connection between the power supply chassis 1 and external equipment, thereby improving the integration and modularity of the power supply chassis 1.

[0076] In some embodiments, see Figure 1 and Figure 2 The fastener 108 can also connect the first copper busbar 107 and the power board 1021 to fix the first copper busbar 107 to the power board 1021.

[0077] In some embodiments, see Figure 4 The first copper busbar 107 is also provided with a plurality of first mounting holes 1070. The plurality of first mounting holes 1070 facilitate the connection between the first copper busbar 107 and the power board 1021 by screws, as well as the connection between the first copper busbar 107 and the second copper busbar 3.

[0078] In one embodiment, the first copper busbar 107 includes a first positive copper busbar 1071 and a first negative copper busbar 1072, which are spaced apart in the height direction.

[0079] In the above embodiments, the height direction can be... Figure 3 In the vertical direction, the first positive copper busbar 1071 and the first negative copper busbar 1072 can be set at intervals in the first direction to make the current transmission path shorter and more balanced, optimize the circuit wiring in the power supply chassis 1, and reduce the failure risk and maintenance difficulty of the power supply chassis 1. At the same time, by setting the positive and negative copper busbars separately, the external wiring of the power supply chassis 1 can also be made more orderly, avoiding wire harness crossover interference and improving the convenience of maintenance.

[0080] In one embodiment, two sets of through holes 1011 are provided, and the two sets of through holes 1011 are provided on both sides of the housing 101 in the width direction; the circuit board 102 and the first copper busbar 107 are both provided in two sets, and each set of first copper busbar 107 is correspondingly provided with each set of through holes 1011.

[0081] In the above embodiments, the width direction can be... Figure 3 In the direction perpendicular to the paper, the two sets of circuit boards 102 and the two sets of first copper busbars 107 can be spaced apart along the width direction, which makes it easy for the power supply chassis 1 to realize multiple power inputs or outputs, and improves the current carrying capacity and power supply stability.

[0082] See Figure 1 and Figure 2 The housing 101 has through holes 1011 on both sides in the width direction, so that each group of first copper busbars 107 can realize the series connection between multiple power supply chassis 1 or the electrical connection between the power supply chassis 1 and external equipment through the through holes 1011, which further improves the integration and modularity of the power supply chassis 1 and enhances the scalability of the power supply chassis 1.

[0083] Reference Figure 2 This application provides a probe assembly, which includes a power supply chassis 1 and a probe 2, and the probe 2 is electrically connected to the positive and negative terminals 104.

[0084] In the above embodiments, by applying the modular power supply chassis 1 to the probe assembly and making the probe 2 electrically connected to the positive and negative terminals 104, not only is the rapid assembly of the power supply chassis 1 and the probe assembly realized, but also the complex assembly method of assembling the various components of the DC-DC converter on the frame 5 of the probe assembly is eliminated, effectively reducing the number of wire harnesses and connection nodes and improving the convenience of maintenance.

[0085] In one embodiment, the positive and negative terminals 104 are six-channel terminals; the number of power supply chassis 1 is three or four.

[0086] In the above embodiments, the design of the six-channel terminal block can better meet the usage requirements of probe assemblies with 18-channel or 24-channel probes. For example, for a probe assembly with 18-channel probes, this embodiment only requires three power supply chassis 1, while in the traditional structural design using four-channel terminal blocks + two-channel terminal blocks, three DC-DC boards with four-channel terminal blocks and three DC-DC boards with two-channel terminal blocks are required, that is, six DC-DC boards are required. For a probe assembly with 24-channel probes, this embodiment only requires four power supply chassis 1, while in the traditional structural design using four-channel terminal blocks + two-channel terminal blocks, four DC-DC boards with four-channel terminal blocks and four DC-DC boards with two-channel terminal blocks are required, that is, eight DC-DC boards are required.

[0087] Therefore, since too many DC-DC boards require more wiring harnesses, there are too many wiring harnesses leading out from the probe assembly, which seriously affects the convenience of probe assembly maintenance. Therefore, the embodiments of this application effectively reduce the number of power supply chassis 1 and wiring harnesses through the above-mentioned settings, optimize the spatial layout of the probe assembly, and significantly improve the applicability and expandability of the probe assembly.

[0088] In one embodiment, there are multiple power supply chassis 1, which are aligned along their length. Each power supply chassis 1 has a first copper busbar 107 in its mounting cavity 1010 along its length. The housing 101 has through holes 1011 at both ends of the first copper busbar 107. The probe assembly also includes a second copper busbar 3, which has a first end 301 and a second end 302. The first end 301 and the second end 302 can electrically connect the two first copper busbars 107 through the through holes 1011 on two adjacent power supply chassis 1, respectively.

[0089] In the above embodiments, multiple power supply chassis 1 are aligned along their length, facilitating the integration and modularization of the power supply chassis 1 and optimizing the spatial layout of the probe components. Each power supply chassis 1 has a mounting cavity 1010 equipped with a first copper busbar 107, which is used to electrically connect various components within each power supply chassis 1, thereby reducing the current transmission path within each power supply chassis 1 and lowering the on-resistance and heat loss of each power supply chassis 1.

[0090] See Figure 3 Each power supply chassis 1 has a housing 101 with through holes 1011 at both ends of the first copper busbar 107, which facilitates the probe assembly to use the second copper busbar 3 to electrically connect the first copper busbar 107 in two adjacent power supply chassis 1, thereby realizing the integration and modularization of the power supply chassis 1, further reducing the number of wire harnesses and improving the convenience of maintenance.

[0091] In some embodiments, see Figure 1 The first copper busbar 107 can form a gap with the through hole 1011, so that the first copper busbar 107 can be hidden inside the housing 101, which facilitates the protection of the first copper busbar 107 by the housing 101 and avoids the external environment from affecting the performance of the first copper busbar 107. When the first copper busbar 107 is hidden inside the housing 101, the first end 301 and the second end 302 of the second copper busbar 3 can pass through the through holes 1011 on two adjacent power supply boxes 1 respectively, and electrically connect the two first copper busbars 107.

[0092] In some embodiments, see Figure 2 The first copper busbar 107 can also pass through the through hole 1011 to be exposed outside the housing 101, so that the two first copper busbars 107 can be electrically connected directly by the first end 301 and the second end 302 of the second copper busbar 3, which improves the electrical connection effect of the two adjacent power supply boxes 1 and enhances the assembly efficiency of the probe assembly.

[0093] In some embodiments, see Figure 5 The first end 301 and the second end 302 of the second copper busbar 3 are both provided with a second mounting hole 300. The second mounting hole 300 facilitates the connection between the second copper busbar 3 and the first copper busbar 107 by using screws.

[0094] In one embodiment, the probe assembly further includes a third copper busbar 4, which has a third end 401 and a fourth end 402. The third end 401 can be electrically connected to the first copper busbar 107 through a through hole 1011 on the power supply chassis 1, and the fourth end 402 can be electrically connected to an external device.

[0095] In the above embodiments, the third copper busbar 4 can electrically connect the first copper busbar 107 and external devices, effectively shortening the current transmission path, reducing transmission loss, and improving the stability and reliability of power supply.

[0096] See Figure 4 The third copper busbar 4 can electrically connect the power supply chassis 1 and external equipment located at both ends of the probe assembly along the length direction, effectively reducing the number of wire harnesses and improving the convenience of maintenance.

[0097] In some embodiments, see Figure 6 The third copper busbar 4 has a third mounting hole 400 at both its third end 401 and fourth end 402. The third mounting hole 400 facilitates the connection between the third copper busbar 4 and the first copper busbar 107 using screws, as well as the connection between the third copper busbar 4 and external equipment.

[0098] In some embodiments, see Figure 4 and Figure 5The first copper busbar 107 is a long copper busbar, and the second copper busbar 3 and the third copper busbar 4 are short copper busbars. The long copper busbars and the short copper busbars are fastened together by screws.

[0099] In one embodiment, the probe assembly further includes a frame 5, to which the power supply chassis 1 is fixed.

[0100] In the above embodiments, the frame 5 can serve as the basic support structure for the probe assembly, providing a stable installation reference and bearing platform for the power supply chassis 1, ensuring that the power supply chassis 1 maintains a relatively fixed position during use, and improving the stability and reliability of the probe assembly.

[0101] In one embodiment, the frame 5 includes a heat dissipation channel 501, which is disposed opposite to the vent 1012 of the housing 101.

[0102] In the above embodiment, a heat dissipation channel 501 is also provided on the frame 5. The heat dissipation channel 501 can be opposite to the vent 1012 and form a smooth heat dissipation airflow, which further enhances the heat dissipation effect, ensures that the temperature of the probe assembly is controllable during continuous operation, and improves the stability of long-term operation.

[0103] Reference Figure 6 This application provides a battery charging and discharging device, which includes a power supply chassis 1 according to this application embodiment, or a probe assembly according to this application embodiment.

[0104] In one embodiment, the battery charging and discharging device further includes a press 6, with the frame 5 slidably connected to the press 6.

[0105] In the above embodiments, the cooperation between the frame 5 and the press 6 enables the formation of a pull-out structure in the battery charging and discharging equipment, thereby improving the maintenance convenience of the probe assembly.
