Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, in particular to a test interface connection mechanism. Background Art

[0002] BMS (BATTERY MANAGEMENT SYSTEM) is a battery management system, which is the link between the battery and the user. It can detect and manage the energy of the battery during charging, discharging and use. At present, in the power battery pack of new energy vehicles, BMS is generally set in the form of an integrated board. Before the power battery pack is produced, the BMS software engineer needs to develop and test the software for the BMS of the power battery pack. During the software development and debugging stage, the BMS software engineer needs to frequently switch between the Debug mode and the Normal mode.

[0003] At present, when debugging in Debug mode, it is necessary to solder the JTAG interface and Debug resistor on the BMS board. At present, BMS software engineers generally use debugging software to debug the BMS board. During debugging, the device equipped with the test software is connected to the JTAG interface through a flexible cable. In the version delivered to the customer after debugging, the Debug resistor on the BMS board needs to be removed to prevent the software written on the BMS board delivered to the client from being tampered with. However, after a problem occurs with the software, it is necessary to observe the operation of the software when the battery pack is running on the vehicle. At this time, it is necessary to re-solder the Debug resistor and reconnect the device equipped with the test software to the JTAG interface on the BMS board through a flexible cable. This is time-consuming and labor-intensive, and frequent plugging and unplugging of the flexible cable is prone to poor contact. Utility Model Content

[0063] Embodiment 1

[0064] The utility model relates to a test interface connection mechanism, which is intended to realize the hot plug operation of a test interface 2 through the connection interface, thereby facilitating the development and debugging of a core board to be tested.

[0065] In terms of overall structure, as shown in FIG. 1 to FIG. 2 , the test interface connection mechanism of this embodiment is used to implement hot-swap operation between the test interface 2 and the core board 7 to be tested, and the connection mechanism includes:

[0066] A connecting seat 1 is electrically connected to the test position of the core board to be tested; a recessed accommodating cavity s for accommodating a test interface 2 with pins 201 is formed in the middle area of ​​the connecting seat 1; a pair of adapter plates 3 are arranged on two opposite sides of the test interface 2; each adapter plate 3 can be snapped onto two opposite side walls of the accommodating cavity s to form an electrical connection with the connecting seat 1; an elastic member 4 is elastically supported between the adapter plate 3 and the test interface 2 to form an electrical connection between the adapter plate 3 and the test interface 2.

[0067] Among them, when the test interface 2 is accommodated in the accommodating chamber s, a pair of adapter plates 3 are elastically driven by the elastic member 4 and are clamped on the two oppositely arranged side walls of the accommodating chamber s; when the pair of adapter plates 3 are operated to move toward each other and disengage from the clamping with the side walls, the test interface 2 can be operated to move away from the accommodating chamber s.

[0068] As set up above, by arranging a pair of adapter plates 3 on both sides of the connecting seat 1, and the adapter plates 3 and the test interface 2 bracket are elastically supported by an elastic member 4, the test interface 2 is pulled out by operating the adapter plate 3 to squeeze the elastic member 4, and by loosening the adapter plate 3, under the elastic action of the elastic member 4 itself, the adapter plate 3 can be clamped on the connecting seat 1 to form an electrical connection with the connecting seat 1, thereby forming an electrical connection between the test interface 2 and the connecting seat 1, realizing the hot plug operation of the test interface 2, and the structure is simple, the operation is convenient, and it is conducive to design implementation.

[0069] Based on the above overall introduction, an exemplary structure of the test interface connection mechanism in this embodiment is as follows: Figures 1 to 6shown.

[0070] Among them, the connecting seat 1 can be electrically connected to the core board to be tested, and a accommodating cavity s for accommodating the test interface 2 is formed on the connecting seat 1, which becomes the installation base of the test interface 2. Through the setting of the connecting seat 1, the test interface 2 does not need to be welded to the core board to be tested. In this embodiment, the connecting seat 1 can be welded to the core board 7 to be tested to fix the plug-in and unplug position of the test interface 2.

[0071] In order to better realize the receiving function of the connecting seat 1, combined with Fig.10 As shown, the connection socket 1 can also be directly constructed on the core board 7 to be tested after the position and shape are pre-planned when the core board 7 to be tested is manufactured.

[0072] Specifically, combined with Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, the connecting socket 1 is constructed to include a base plate, a accommodating cavity s recessed in the middle area of ​​the connecting socket 1, and a plurality of electrical connecting plates 5 spaced apart on the base plate. The number and spacing of the electrical connecting plates 5 can be set according to the layout requirements of the interface 2 to be tested.

[0073] The electrical connection sheet 5 may be, for example, a copper sheet embedded in the connection base 1 . The copper sheet has good electrical conductivity and is easy to shape, process and manufacture, thus facilitating design implementation.

[0074] In addition, a recessed snap-in groove 101 is formed on the side wall of the accommodating cavity s, and the snap-in groove 101 has a length extending along the length direction of the adapter plate 3; a snap-in block 301 protruding outward toward the side wall is provided on each adapter plate 3, and the snap-in block 301 can be adaptably snapped into the snap-in groove 101. The setting of the snap-in groove 101 and the snap-in block 301 makes the connection between the adapter plate 3 and the connecting seat 1 more secure, the structure is simple, and it is convenient for design implementation.

[0075] It is worth mentioning that in order to reduce processing costs, the copper sheet may not be provided on the bottom surface where the snap-in slot 101 contacts the snap-in block 301. The copper sheet may be provided on the side or top surface where the snap-in block 301 contacts the snap-in slot 101. It is only necessary to ensure that the snap-in slot 101 and the snap-in block 301 can be electrically connected.

[0076] In order to ensure the connection effect between the test interface 2 and the connection socket 1 , the test interface 2 is provided with a side pin 202 , and the adapter board 3 is provided with a plug hole 302 to cooperate with it.

[0077] Specifically, the side pins 202 are distributed on two opposite sides of the test interface 2 and are electrically connected to the pins 201 of the test interface 2. The plug hole 302 is provided on the side of the adapter board 3 facing the test interface 2 to receive the side pins 202. At the same time, the elastic member 4 is received in the plug hole 302 and elastically contacts the pins 201. Through the arrangement of the side pins 202 and the plug hole 302, the test interface 2 and the adapter board 3 are configured to be detachably connected, which is convenient for replacing different types of test interfaces 2. The structure is simple, the versatility is good, and the design implementation is convenient.

[0078] In order to better realize the electrical connection between the test interface 2 and the adapter board 3, Figures 1 to 4 As shown, an electrical connection piece 5 is embedded on the adapter plate 3 constituting the plug hole 302, and the electrical connection piece 5 constitutes an electrical connection between the connecting seat 1 and the elastic member 4. Through the setting of the electrical connection piece 5, the test interface 2 and the elastic member 4 can be electrically connected by abutment, and then electrically connected to the connecting seat 1, and the elastic member 4 is accommodated in the plug hole 302, which is beneficial to protecting the elastic member 4 and preventing the elastic member 4 from falling off due to external factors. The structure is simple and convenient for design implementation.

[0079] It is worth mentioning that, combined with Figure 5 and Figure 6 As shown, in order to better accommodate the elastic member 4, one end of the elastic member 4 in this embodiment is fixedly connected to the electrical connection sheet 5 in the plug hole 302, and the other end is a free end, which only needs to abut against the side pin 202 inserted into the plug hole 302. In this way, the elastic member 4 can be better accommodated to avoid the loss of the elastic member 4 due to plugging and unplugging the test interface 2. The elastic member 4 in this embodiment can be, for example, a spring, which is easy to process and manufacture the test interface 2, and the elastic state switching operation of the spring itself is simple, which is conducive to design implementation.

[0080] In addition, in order to be applicable to the situation where the setting position of the test interface 2 is not convenient for connecting external devices, Figures 7 to 9 As shown, the connection mechanism in this embodiment further includes a transfer device 6, and the transfer device 6 includes a transfer port 601 and a fixing platform 602 matched therewith.

[0081] Specifically, the adapter 601 in this embodiment can be operably inserted into the pin 201 of the test interface 2 , and the adapter 601 is provided with a jack 6011 adapted to the test interface 2 .

[0082] The fixing platform 602 in this embodiment can be detachably maintained at the transfer position near the test interface 2, and is electrically connected to the transfer interface 601. The fixing platform 602 is provided with a lead pin 603 extending outward from the fixing platform 602, and the extension direction of the lead pin 603 and the insertion direction of the transfer interface 601 and the pin 201 are set at an angle. Through the setting of the transfer device 6, the test interface connection mechanism can realize the connection angle change. When the setting angle of the test interface 2 is not conducive to connection, it is changed to an angle that is easy to connect, which is conducive to the test interface 2 connecting to external equipment. The structure is simple and convenient for design implementation.

[0083] In order to better adjust the insertion angle between the adapter 601 and the pin 201, the adapter 601 can be twisted and accommodated in the fixing platform 602. By twisting the adapter 601 in the fixing platform 602, the pluggable angles of the adapter 601 are more diverse, which is conducive to design implementation.

[0084] In order to facilitate the twisting of the transfer port 601 , in this embodiment, an operating handle 6012 is further provided at the top of the transfer port 601 , and the operating handle 6012 at the top of the transfer port 601 is an insulating member.

[0085] In order to better cooperate with the twisting of the adapter 601, the fixed platform 602 in this embodiment is constructed into a cylindrical shape, and the adapter 601 can be plugged and unplugged and accommodated in the fixed platform 602, and can be operated to twist around its own axis. The outer surface of the adapter 601 contacts and cooperates with the inner surface of the fixed platform 602 to form an electrical connection between the adapter 601 and the fixed platform 602. The cylindrical fixed platform 602 structure is conducive to processing and manufacturing. The plugging and unplugging of the adapter 601 is easier to operate through the cylindrical fixed platform 602 structure, and the outer surface of the adapter 601 contacts and cooperates with the inner surface of the fixed platform 602 to form an electrical connection, making the use and operation of the adapter 601 convenient and conducive to design and implementation.

[0086] In order to more stably connect the adapter 601 to the test interface 2, a detachable retaining member 604 is provided on the fixed platform 602. The retaining member 604 and the adapter 601 are blocked and cooperated with each other to form an axial position maintenance of the adapter 601 in the fixed platform 602. Through the setting of the retaining member 604, the adapter 601 and the fixed platform 602 are limited, so that the connection between the adapter 601 and the test interface 2 is more stable, which is conducive to design implementation.

[0087] As in the present embodiment, the retaining member 604 is a fixing ring fixed on the adapter, and the retaining member 604 is clamped on the fixing platform 602. A plurality of clamping blocks 6041 are provided on the surface of the retaining member 604 facing the fixing platform 602. In cooperation with the clamping blocks 6041, a clamping groove 6021 for clamping the clamping blocks 6041 is provided on the top of the fixing platform 602. The retaining member 604 can be made of rubber, for example. The clamping block 6041 is slightly larger than the size of the clamping groove 6021 on the fixing platform 602 to achieve an interference fit between the clamping block 6041 and the clamping groove 6021, so that the retaining member 604 is clamped on the fixing platform 602.

[0088] In addition, combined Figure 7 As shown, in order to facilitate the transfer interface 601 to be kept on the core board to be tested, a clamping portion 605 is fixedly connected to the fixed platform 602. Since the clamping portion 605 clamps the core board to be tested, the fixed platform 602 is maintained at the transfer position near the test interface 2. Through the setting of the clamping portion 605, the connection between the transfer interface 601 and the core board to be tested is more stable and easy to operate, which is conducive to design implementation.

[0089] Specifically, the clamping portion 605 in this embodiment includes a first clamping arm 6051 , a second clamping arm 6052 swingably disposed on the first clamping arm 6051 , and a return spring 6053 disposed between the first clamping arm 6051 and the second clamping arm 6052 .

[0090] Among them, the overall appearance of the first clamp arm 6051 and the second clamp arm 6052 are both plate-shaped, and the first clamp arm 6051 has a first connecting portion 6054 extending from the middle of the two side surfaces along the width direction toward the second clamp arm 6052. In coordination with this, the second clamp arm 6052 has a second connecting portion 6055 extending from the middle of the two side surfaces along the width direction toward the first clamp arm 6051. When the first clamp arm 6051 and the second clamp arm 6052 are assembled into one, the first connecting portion 6054 can be inserted between the second connecting portion 6055, and the first connecting portion 6054 and the second connecting portion 6055 are both provided with a pin shaft 6056, and the two ends of the reset spring 6053 are respectively connected to the ends of the first clamp arm 6051 and the second clamp arm 6052 away from the core plate to be tested.

[0091] In order to facilitate the installation of the clamping portion 605, Figure 7 As shown, a connection groove 6022 is provided on the outer wall of the fixing platform 602 , and after the end of the first clamping arm 6051 is inserted into the connection groove 6022 , it is fixed to the connection groove 6022 by bolts.

[0092] It is worth mentioning that the reset spring 6053 is in a normal state when not operated. When the clamping part 605 is clamped on the core board to be tested, the clamping part 605 is first squeezed away from the end of the core board to be tested. At this time, the reset spring 6053 is in a compressed state. When the adapter 601 is plugged into the pin 201 of the test interface 2, the elasticity of the reset spring 6053 makes the adapter 601 further fixed on the test interface 2, thereby improving the stability of the connection between the adapter 601 and the test interface 2.

[0093] When using, combine Figures 1 to 10 As shown, first insert the side pin 202 of the test interface 2 into the adapter board 3, then squeeze the adapter board 3 so that the two adapter boards 3 are close to each other, clamp the test interface 2, and put them into the accommodating cavity s of the connecting seat 1 together with the test interface 2. Under the action of the elastic member 4, the two adapter boards 3 are clamped in the connecting seat 1, and then development and debugging can be carried out. After the development and debugging is completed, squeeze the adapter board 3 so that the two adapter boards 3 are close to each other, clamp the test interface 2, and detach from the connecting seat 1 together with the test interface 2.

[0094] When the setting angle of the test interface 2 is not conducive to development and debugging, the angle conversion of the test interface 2 is achieved through the adapter 6. First, the adapter is twisted to the corresponding angle and inserted into the fixed platform 602. Then, the clamping part 605 is squeezed away from one end of the core board to be tested, and the adapter is inserted into the test interface 2. The angle conversion of the test interface 2 can be achieved through the lead-out pin 603 arranged on the side of the fixed platform 602.

[0095] In this embodiment, the adapter plate 3 is clamped and inserted into the connecting seat 1, and the test interface 2 is kept on the connecting seat 1 by the elastic member 4, so that the hot plug operation of the test interface 2 is realized, which is beneficial to development and debugging. Through the setting of the adapter device 6, the angle of the test interface 2 that is inconvenient to connect is changed to the angle of the test interface 2 that is easy to connect, which is beneficial to development and testing.

[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
