Description

Technical Field

[0001] This invention belongs to the field of hydrogen-oxygen fuel cell testing and monitoring technology, and in particular to a detachable CVM module for hydrogen-oxygen fuel cells. Background Technology

[0002] The CVM module, also known as the voltage detection module, is mainly used to monitor changes in the module voltage of a hydrogen-oxygen fuel cell, preventing damage to the fuel cell caused by a consistently low module voltage.

[0003] Currently known CVM modules used for testing and monitoring hydrogen-oxygen fuel cells all have space reserved for metal inserts at the front end, with space at the rear end for signal line insertion. However, with the research and development and testing of hydrogen-oxygen fuel cells, more and more CVM modules are appearing before testers.

[0004] Currently, most CVM modules for hydrogen-oxygen fuel cells have relatively fixed structures, and they generally have several slots pre-cut for inserting metal plates. This structure can only accommodate metal plates of the corresponding size and number, which has certain limitations. For metal plates of other sizes and numbers, additional mold processing is required, which increases costs. Utility Model Content

[0005] Purpose of the utility model: To provide a detachable CVM module for hydrogen-oxygen fuel cells, so as to solve the problem that most existing CVM module structures for hydrogen-oxygen fuel cells are not easy to adapt to metal inserts of different sizes and numbers. Technical solution

[0006] A detachable CVM module for hydrogen-oxygen fuel cells includes a fixed body and at least one inspection component detachably disposed on the fixed body. The inspection component includes an inspection test socket for inserting and installing metal inserts, a signal connector inserted and connected to the inspection test socket, and a sliding connector disposed on the inspection test socket. A sliding track is provided on the fixed body, and an opening is provided at the end of the sliding track. The sliding connector enters the sliding track through the opening and slides in connection with the sliding track, so that the inspection test seat can move horizontally on the fixed body along the extension direction of the sliding track.

[0007] In some possible embodiments, the inspection test base is provided with a test slot for inserting a metal insert, and the inspection test base is also provided with a signal access slot for inserting a signal connector, the signal access slot being connected to the test slot.

[0008] In a further embodiment, the sliding connector includes a sliding block that enters the sliding track from the opening; the sliding block and the sliding track can be used to assemble, disassemble, and slide the inspection test seat.

[0009] In a further embodiment, two sliding blocks are symmetrically arranged at the bottom of the inspection test seat, and the two sliding blocks are slidably connected to the two sliding rails respectively. The two sliding rails are opened parallel to each other on the fixed body.

[0010] In a further embodiment, the two sliding tracks are a first track and a second track, and each of the first track and the second track has an opening at one end on the same side for the two sliding blocks to enter. The other end of the first track also has a through opening communicating with the opening. The other end of the second track is closed, and the bottom of the second track is open by opening a through groove. The through groove is designed to cooperate with the limiting component to limit the inspection test seat.

[0011] In a further embodiment, the inspection test stand is also provided with a limiting member, which is disposed at the bottom end of the sliding block that is slidably connected to the second track, and the top end of the sliding block is connected to the inspection test stand.

[0012] In a further embodiment, the limiting member includes a spring and a limiting block, one end of the spring is fixed to the other end of the sliding block, and the other end of the spring is rotatably connected to the limiting block; When the limiting member enters the second track in its original state, both the limiting block and the spring are inside the second track and the length of the spring is a first preset length. The limiting block is parallel to the centerline in the length direction of the through groove. When the limiting member is in the limiting state in the second track, the spring is pulled so that the limiting block extends out of the through groove. The limiting block is rotated so that the limiting block intersects the center line in the length direction of the through groove, and the spring is at the second preset length. The inspection test seat can be quickly limited by simply and quickly operating the limiting block.

[0013] In a further embodiment, the inspection test stand is also provided with a docking component, and the docking components on two adjacent inspection test stands are staggered.

[0014] In a further embodiment, the docking assembly includes two external protrusions and two internal grooves. The two external protrusions are symmetrically fixed on the outer wall of the inspection test base, and the two internal grooves are symmetrically formed on the outer wall of the inspection test base; thus, the two inspection test bases can be made to fit together.

[0015] In a further embodiment, the test slot includes a first slot and a second slot arranged in sequence, and a limiting slot is provided between the first slot and the second slot. The limiting slot is for a limiting insert to be inserted therein to limit the metal insert installed in the first slot and the second slot.

[0016] The beneficial effects of this utility model are as follows: This application sets up a fixed main body, on which a detachable inspection test seat is fitted. After selecting an appropriate number and size of inspection test seats and installing them on the fixed main body via sliding connectors, the usage position can be flexibly adjusted to adapt to metal inserts. Unlike most existing CVM modules that can only adapt to one type of metal insert, the movable inspection test seat of this application is more flexible. The sliding connectors allow for both movement and disassembly of the inspection test seats. Generally, only the dimensions of the sliding connector need to be determined. The sliding connector can connect to inspection test seats of different sizes and always remain connected to the fixed main body. An appropriate number and size of inspection test seats can be installed on the fixed main body according to the actual situation to meet different testing needs. One fixed main body can accommodate multiple numbers and sizes of inspection test seats, and disassembly and assembly can be achieved simply through the sliding connectors. This is simple and convenient, reducing mold opening costs and effectively lowering the development costs of new products, thus possessing good practicality. Attached Figure Description

Detailed Implementation

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. Example 1

[0028] Reference Figures 1-5 This embodiment discloses a detachable CVM module for hydrogen-oxygen fuel cells, comprising a fixed body 1 and at least one detachable inspection component 2 mounted on the fixed body 1. The inspection component 2 includes an inspection test base 4 for inserting and installing metal inserts, a signal connector inserted and connected to the inspection test base 4, and a sliding connector 3 mounted on the inspection test base 4. The signal connector includes a signal line and a terminal block at one end of the signal line. The terminal block is inserted into the inspection test base 4 to make contact with the metal inserts mounted in the inspection test base 4 for signal transmission. A sliding rail 11 is provided on the fixed body 1, with an opening at one end. The sliding connector 3 enters the sliding rail 11 through the opening and slides through the sliding rail 11, allowing the inspection test base 4 to move horizontally on the fixed body 1 along the extension direction of the sliding rail 11. This enables the position adjustment of a single inspection component 2, and allows the position of two adjacent inspection components 2 on the fixed body 1 to be adjusted according to the size of different metal inserts or actual usage requirements.

[0029] The inspection test base 4 has a test slot 41 for inserting a metal insert, and a signal access slot 42 for inserting a signal connector. The signal access slot 42 is connected to the test slot 41. Figure 1The test slot 41 shown is located in the vertical direction of the inspection test base 4, so that the metal insert can be inserted into the test slot 41 from top to bottom. The signal access slot 42 is located in the horizontal direction of the inspection test base 4 and is located on one side of the inspection test base 4. This arrangement will not affect the distribution and use of other components.

[0030] The sliding connector 3 includes a sliding block 31, which is horizontally pushed into the sliding track 11 from the opening; the sliding engagement of the sliding block 31 and the sliding track 11 completes the position adjustment of the single inspection test seat 4 on the fixed body 1, and further, as... Figure 2 The sliding block 31 shown has an arrow-shaped structure and moves in a sliding track that matches its shape. The arrow-shaped sliding block and the sliding track can have a certain limiting effect in the vertical direction to prevent the sliding block from leaving the sliding track.

[0031] To further ensure the stability of the inspection test seat 4, two sliding blocks 31 are symmetrically arranged at the bottom of the inspection test seat 4. The two sliding blocks 31 are slidably connected to the two sliding rails 11 respectively. The two sliding rails 11 are parallel to each other on the fixed body 1. The sliding blocks 31 and sliding rails 11 arranged in pairs can improve the balance of the inspection test seat 4 in the sliding or stationary state, making the connection between the inspection test seat 4 and the fixed body 1 tighter.

[0032] The two sliding tracks 11 are a first track 111 and a second track 112. Both the first track 111 and the second track 112 have openings at one end on the same side for the two sliding blocks 31 to enter. The other end of the first track 111 also has a through-hole that communicates with the opening. The two ends of the first track 111, which are the communicating opening and the through-hole respectively, can save costs to a certain extent. The other end of the second track 112 is closed. The closed state can limit the maximum movement position of the inspection test seat 4 on the fixed body 1. The bottom of the second track 112 is open by opening a through-slot. The through-slot is used to cooperate with the subsequent use of the limiting member 32. The length of the through-slot is consistent with that of the second track 112. When the sliding block 31 on the inspection test seat 4 corresponding to the second track 112 enters the second track 112 from the opening position and reaches the appropriate position, part of the limiting member 32 can pass through the through-slot and be stuck at the bottom of the fixed body 1, so that the position of the inspection test seat 4 is limited.

[0033] In order to ensure that the inspection test seat 4 can be slidably adjusted when it needs to be moved, and can be fixed in position when it reaches the appropriate position, the inspection test seat 4 is also provided with a limiting member 32. The limiting member 32 is set at the bottom end of the sliding block 31 which is slidably connected to the second track 112, and the top end of the sliding block 31 is connected to the inspection test seat 4.

[0034] The limiting component 32 includes a spring 321 and a limiting block 322. One end of the spring 321 is fixed to the other end of the sliding block 31, and the other end of the spring 321 is rotatably connected to the limiting block 322. Furthermore, the size of the limiting block 322 needs to match the size of the second track 112. Specifically, the width of the limiting block 322 is slightly smaller than the width of the second track 112, allowing the limiting block 322 to enter the second track 112 in its original state. The length of the limiting block 322 is greater than the width of the second track 112, so that when the limiting block 322 rotates, it can be locked outside the through groove for limiting its position. Figure 2 As shown, when the limiting member 32 is in its original state and enters the second track 112, both the limiting block 322 and the spring 321 are inside the second track 112, and the length of the spring 321 is a first preset length. The limiting block 322 is parallel to the centerline of the through groove in the length direction. At this time, the spring 321 is in its original state and is not subjected to external tension or compression. The horizontal position of the lower surface of the limiting block 322 is higher than or equal to the horizontal position of the lower surface of the through groove, so that the limiting block 322 and the spring 321 can completely enter the sliding track 11 together with the sliding block 31. Figure 4As shown, when the limiting member 32 is in the limiting state in the second track 112, the spring 321 is pulled, causing the limiting block 322 to extend out of the through groove. Rotating the limiting block 322 causes it to intersect the centerline of the through groove along its length, and the spring 321 is at a second preset length. As the inspection test seat 4 slides to a suitable position, it is manually moved from the bottom through groove of the fixed body 1 into the sliding track 11 to pull the limiting block 322 parallel out until it extends out of the through groove, causing the spring 321 to extend. The limiting block 322 is rotated to a certain angle so that its centerline intersects the centerline of the sliding track 11, and the limiting block 322... The rotation angle does not need to be specified in degrees. Simply rotate the limiting block 322 until its centerline is offset from the centerline of the second track 112 to prevent their parallel centerlines from being parallel. Then release the limiting block 322 so that the spring 321 contracts to the second preset length. The tension generated by the spring 321 on the limiting block 322 causes the limiting block 322 to be stuck outside the through groove, thereby limiting the position of the sliding block 31 and the inspection test seat 4. This limiting structure is simple and quick to operate. Since the bottom of the fixed body 1 is suspended when used with several inspection test seats 4, even if the limiting block 322 protrudes from the bottom of the fixed body 1, it will not affect the stability of the fixed body 1.

[0035] The implementation principle of this embodiment is as follows: Select an appropriate number of inspection test seats 4 according to the test requirements, install the corresponding sliding blocks 31 on the inspection test seats 4 onto the fixed body 1 in sequence through the sliding rail 11, and limit the position of the inspection test seats 4 by the tension spring 321 and the rotation limit block 322. Then, insert the metal insert into the test slot 41, and connect the wiring terminal from the signal access slot 42 to make it contact the metal insert for testing. Example 2

[0036] Based on Example 1, the difference from Example 1 is that the reference is... Figure 1 , Figures 6-8 This embodiment discloses a detachable CVM module for hydrogen-oxygen fuel cells. The inspection test seat 4 is also provided with a docking component 43. The docking components 43 on two adjacent inspection test seats 4 are staggered. When two inspection test seats 4 need to be fitted together, the outer walls of the adjacent inspection test seats can be fitted together by combining the two docking components 43, making the connection between the two inspection test seats 4 tighter.

[0037] The docking assembly 43 includes two external protrusions 432 and two internal grooves 431. The two external protrusions 432 are symmetrically fixed to the outer wall of the inspection test base 4, and the two internal grooves 431 are symmetrically formed on the outer wall of the inspection test base 4. The internal grooves 431 are not connected to the test grooves 41. The two external protrusions 432 are integrally formed with the inspection test base 4. Therefore, as Figure 5 As shown, the signal access slot 42 is set between the outer protrusions 432. While satisfying the mating fit between the outer protrusions 432 and the recessed grooves 431, the size of the signal access slot 42 can also be enlarged to better facilitate the connection of the wiring terminals. When two inspection test seats 4 need to be fitted together, two inspection test seats 4 are selected so that the outer protrusion 432 on one inspection test seat 4 corresponds to the recessed groove 431 on the other inspection test seat 4. When the two inspection test seats 4 approach each other until they fit together, the corresponding outer protrusions 432 and recessed grooves 431 are mated together.

[0038] The implementation principle of this embodiment is as follows: Select an appropriate number of inspection test seats 4 according to the test requirements, and install the corresponding sliding blocks 31 on the inspection test seats 4 onto the fixed body 1 in sequence through the sliding rail 11. It should be noted that if it is necessary for adjacent inspection test seats 4 to fit together, when selecting inspection test seats 4, the outer protrusions 432 on two adjacent inspection test seats 4 should be staggered with the concave grooves 431. Then, the position of the inspection test seats 4 can be limited by the tension spring 321 and the rotation limit block 322. After that, insert the metal insert into the test groove 41, and then connect the wiring terminal from the signal access groove 42 to make it contact the metal insert for testing. Example 3

[0039] Based on Example 1, the difference from Example 1 is that the reference is... Figures 1-2 and Figures 4-5This embodiment discloses a detachable CVM module for a hydrogen-oxygen fuel cell. The test slot 41 includes a first slot 411 and a second slot 412 connected in sequence. A limiting slot 413 is provided between the first slot 411 and the second slot 412. The limiting slot 413 allows a limiting insert to be vertically inserted to limit the metal insert installed in the first slot 411 and the second slot 412. The first slot 411 is inclined and its position is higher than that of the second slot 412. Preferably, the limiting slot 413 is located at the angle between the first slot 411 and the second slot 412. To achieve a better limiting effect, after inserting the metal insert into the first slot 411 and the second slot 412 from top to bottom, an external limiting insert is inserted into the limiting slot 413 to limit the metal insert in the first slot 411 and the second slot 412. The limiting insert and the limiting slot 413 are interference-fitted. The limiting insert is a simple and common sheet-like structure with a certain thickness, and its thickness matches the limiting slot. Therefore, its shape and structure will not be described in detail here. This presses down the metal insert, preventing it from being pulled out of the first slot 411 and the second slot 412. Furthermore, the specific length of the limiting insert is not limited due to its low cost. Because of its low cost, the thickness of several inspection test seats can be adjusted. For example, a group of three inspection test seats can be equipped with a limiting insert of one length, while a group of five inspection test seats can be equipped with a limiting insert of another length. The design can be customized according to actual usage. Furthermore, if all five inspection test seats have metal inserts installed simultaneously, since the installation and removal of multiple metal inserts are performed concurrently, limiting inserts of other sizes can be used to connect with limiting slots in the middle or other positions. By limiting some of the metal inserts, the limiting of all metal inserts can be achieved. When multiple inspection test seats are in use... After the test base 4 is installed on the fixed body 1, the second track 112 limits the number of installations. Therefore, a limiting insert can be inserted into the limiting slot 413 of multiple parallel-installed inspection test bases 4. The limiting insert not only limits the metal insert, but also limits the position of each inspection test base 4 to a certain extent. The installation and removal of the limiting insert is convenient and quick. The limiting insert is made of insulating material and has a certain degree of hardness. When limiting is required, a little force is applied manually to insert the appropriate limiting insert from top to bottom into the limiting slot, which can fix the metal insert in the inspection test base.

[0040] The implementation principle of this embodiment is as follows: Select an appropriate number of inspection test seats 4 according to the test requirements, and install the corresponding sliding blocks 31 on the inspection test seats 4 onto the fixed body 1 in sequence through the sliding rail 11. The position of the inspection test seats 4 can be limited by the tension spring 321 and the rotation limit block 322. After inserting the metal insert into the test slot 41, use the limit insert to make it simultaneously insert into the limit groove of the inspection test seat 4 on the fixed body 1 to realize the limit of all metal inserts. Then, connect the wiring terminal from the signal access slot 42 to make it contact the metal insert for test operation.
