Description

Technical Field

[0001] The invention belongs to the field of proton exchange membrane fuel cells, and in particular relates to a position-adjustable battery voltage inspection probe, a socket and a use method. Background Art

[0002] Proton exchange membrane fuel cell (PEMFC) is an efficient and clean energy conversion device with the characteristics of cleanliness, high efficiency and low noise. The fuel cell stack is composed of multiple single cells connected in series to increase the voltage to meet the use requirements. The consistency of the voltage of multiple single cells is an important factor to monitor during the operation of the stack, which affects the long-term operation life of the stack. Therefore, real-time monitoring of the voltage of multiple single cells is of great significance.

[0003] There are currently two ways to collect single battery voltage:

[0004] The first method is to reserve a voltage collection probe socket on the single battery plate, and insert the voltage collection probes into the reserved interface one by one during the test. This method has the following disadvantages: First, there are many probes (mostly 250-300), which is very inefficient when plugging and unplugging, and it is easy to miss or plug in the wrong place; second, this connection is not reliable enough, and it is very easy to fall off or contact adjacent probes to cause a short circuit, which can seriously burn the battery stack.

[0005] The second method is to fix the voltage collection probe inside the single battery during product design, and directly insert the probe into the external voltage collection connector during testing. Each connector can be inserted with multiple probes at the same time, which improves efficiency. However, there are still problems: First, during the battery stack manufacturing process, the probe is exposed to the outside of the battery and is easily scratched and damaged during transportation; second, the reliability of the connector is still not high, and there is a risk of falling and losing the voltage signal; third, there are assembly errors in the stacking of multiple single batteries, and the probe position is deviated, resulting in the inability to fully insert the connector. Summary of the invention

[0006] The purpose of the present invention is to provide a battery voltage inspection probe, a socket and a method of use with adjustable position, so as to solve the problems of easy scratches and damage during transportation and assembly errors during the stacking of multiple single batteries.

[0007] The objective of the present invention is achieved through the following technical means: a position-adjustable fuel cell voltage inspection probe, comprising a probe body, the probe body comprising a cylindrical rotating part, a rotating hole penetrating the rotating part from the lower bottom to the upper bottom is opened in the center of the rotating part, a plurality of locking protrusions are arranged on the front and back sides of the rotating part, i.e., the upper and lower bottom surfaces, and a plug part and a dial key are also connected to the side of the rotating part, and the dial key protrudes outward.

[0008] The plurality of locking protrusions on the same surface are distributed on the circumference of the same circle with the rotating hole as the center.

[0009] The plug part is a triangular prism structure, the cross section of the triangular prism is a triangle, and the base of the triangle is an arc shape matching the rotating part.

[0010] One side of the triangle is an arc-shaped side that is concave toward the inside of the triangle, and the other side is an arc-shaped side that is convex toward the outside of the triangle. The top of the triangle forms a hook that is inclined toward the concave arc-shaped side.

[0011] The dial key is located at the connection between the protruding arc edge of the plug part and the rotating part.

[0012] A position-adjustable fuel cell voltage inspection socket comprises an anode plate and a cathode plate. The anode plate is provided with a probe slot matching a probe body. The probe slot comprises a rotation slot and a plug slot. A rotation pin matching a rotation hole is arranged at the center of the rotation slot. Rotation guide rings matching locking convex points are provided on the surfaces of the probe slot and the cathode plate.

[0013] The bottom of the rotating guide rail ring is also provided with a locking concave point which is sunken downwards, and the locking concave point matches the locking convex point.

[0014] The depth of the rotating guide rail ring is less than the height of the locking protrusion.

[0015] The rotating groove is also connected with a positioning pin, and the positioning pin is located outside the rotating guide ring.

[0016] A method for using a position-adjustable fuel cell voltage inspection socket.

[0017] Insert the rotating part of the probe body into the rotating pin, align the locking protrusions on both sides with the rotating guide rings of the cathode plate and the anode plate, extend the dial key out of the probe slot, and install the cathode plate and the anode plate;

[0018] When in use, the probe body is rotated around the rotating pin through the exposed dial key, so that the plug part is exposed and connected with the slots of other parts;

[0019] When not in use, the probe body is rotated around the rotating pin through the exposed dial key, so that the plug part is rotated into the plug slot. Only the dial key of the entire probe is exposed to the outside, thus preventing the plug part from being scratched and damaged.

[0020] The beneficial effects of the present invention are:

[0021] 1. The probe and socket structure are located inside the single cell, that is, the cathode plate and the anode plate. The rotatable probe can be adjusted to the inside during assembly to avoid scratches and damage during transportation and assembly.

[0022] 2. The rotatable probe body allows each single cell to actively adjust the probe position. In case of probe misalignment caused by misalignment of single cell assembly, all probe bodies are adjusted to the same position before the connector is inserted.

[0023] 3. The plug is narrow at the top and wide at the bottom, and the side is an arc-shaped variable cross-section design, so that the connector can insert the probe by its own gravity, which can resist vibration conditions and has high reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] [Example 1]

[0035] like Figure 1As shown, a position-adjustable fuel cell voltage inspection probe includes a probe body, which includes a cylindrical rotating part 1, a rotating hole 2 is opened in the center of the rotating part 1 and passes through the rotating part 1 from the lower bottom to the upper bottom, and a plurality of locking protrusions 3 are arranged on the front and back sides of the rotating part 1, that is, the upper bottom and the lower bottom surfaces, and a plug part 4 and a dial key 5 are also connected to the side of the rotating part 1, and the dial key 5 protrudes outward.

[0036] The probe consists of two parts. The cylindrical rotating part 1 is used to make the probe as a whole rotatable. Since it is installed in the battery, it is very thin and can be regarded as a disc with a rotating hole 2 in the middle. Several raised locking bumps 3 are provided on the front and back sides of the rotating part 1 to lock the rotation angle of the rotating part 1. On the side of the cylinder, a plug part 4 is connected for connecting with other connectors; the raised dial key 5 is for facilitating the rotation of the rotating part 1 of the probe.

[0037] The plurality of locking protrusions 3 on the same surface are distributed on the circumference of the same circle with the rotating hole 2 as the center.

[0038] like Figure 3 and Figure 4 As shown, a plurality of locking protrusions 3 on the same surface are distributed on the circumference of a circle;

[0039] Specifically, the circle on the front side can be of a different size from the circle on the back side, as long as they match the rotating guide ring 12 on the corresponding electrode plate.

[0040] For example, if the rotating guide ring 12 on the cathode plate 7 is a circle with a diameter of 1 cm, then the locking protrusions 3 on one side of the corresponding rotating part 1 are also distributed on a circle with a diameter of 1 cm;

[0041] The rotating guide ring 12 of the anode plate 6 is a circle with a diameter of 2 cm, and the locking protrusions 3 on one side of the corresponding rotating part 1 are also distributed on a circle with a diameter of 2 cm. The locking protrusions 3 on both sides can be distributed on circles of different diameters.

[0042] like Figure 1 As shown, the plug portion 4 is a triangular prism structure, the cross section of the triangular prism is a triangle, and the base of the triangle is an arc that matches the rotating portion 1.

[0043] The plug portion 4 also has thickness, and its cross section is a triangle with a narrow top and a wide bottom. In three dimensions, it is a triangular prism structure. Since it is connected to the rotating portion 1 of the cylinder, the part corresponding to the bottom side of the triangle is changed into an arc shape matching the rotating portion 1, thereby connecting the plug portion 4 and the rotating portion 1 together. In actual production, the plug portion 1 and the rotating portion 4 can be formed as one piece.

[0044] One side of the triangle is an arc-shaped side that is concave toward the inside of the triangle, and the other side is an arc-shaped side that is convex toward the outside of the triangle. The top of the triangle forms a hook that is inclined toward the concave arc-shaped side.

[0045] Furthermore, one of the two sides of the triangle is changed into an arc-shaped edge recessed into the interior of the triangle, and the other side is an arc-shaped edge protruding outwardly of the triangle. In this way, the entire plug portion 4 becomes a curved hook with the tip facing the recessed side of the triangle. The plug portion 4 as a whole presents a variable cross-section design with a narrow tip and a wide bottom. When the probe body is rotated to any position, the needle, that is, the tip of the curved hook can remain facing upward. When the product is under vibration and other working conditions, the plug relies on its own gravity to lock the needle downward, thereby achieving high reliability.

[0046] The dial key 5 is located at the connection between the protruding arc edge of the plug part 4 and the rotating part 1 .

[0047] The dial key 5 is located on the rotating part 1 , close to the half side of the protruding arc side of the head 4 .

[0048] A position-adjustable fuel cell voltage inspection socket comprises an anode plate 6 and a cathode plate 7. The anode plate 6 is provided with a probe slot matching a probe body. The probe slot comprises a rotation slot 8 and a plug slot 9. A rotation pin 10 matching a rotation hole 2 is arranged at the center of the rotation slot 8. A rotating guide ring 12 matching a locking protrusion 3 is provided on the surface of the probe slot and the cathode plate 7.

[0049] The socket is set at one of the four corners of the anode plate 6 and the cathode plate 7. Figure 2-6 For example, set it in the lower right corner.

[0050] The lower surface of the cathode plate 7 and the upper surface of the anode plate 6 are opposite to each other, and a probe groove is opened at the lower left corner of the upper surface of the anode plate 6 for placing the probe body;

[0051] Specific as Figure 7 As shown, the probe groove is divided into a rotating groove 8 for placing the rotating part 1, the shapes of the two are matched, and the size ensures that the edge of the rotating part 1 does not expose the bottom edge and left side of the anode plate.

[0052] Similarly, the plug slot 9 has a size and shape that ensures that the lower plug part 4 can be completely accommodated during rotation to prevent the plug part 4 from being exposed.

[0053] A rotating pin 10 is connected to the rotating groove 8 , and the rotating hole 2 is inserted into the rotating pin 10 , so that the probe body rotates around the rotating pin 10 .

[0054] The dial key 5 is always exposed outside the anode plate 6 and the cathode plate 7.

[0055] The upper surface of the rotating groove 8 of the anode plate 6 and the lower surface of the cathode plate 7 are provided with an annular rotating guide ring 12, and the rotating guide ring 12 matches the circumference corresponding to the locking protrusion 3. The locking protrusions 3 on both sides of the rotating part 1 fall into the rotating guide rings 12 of the two pole plates respectively, so that when rotating, the locking protrusions 3 rotate along the rotating guide ring 12.

[0056] The bottom of the rotating guide ring 12 is also provided with a locking concave point 13 which is recessed downwards, and the locking concave point 13 matches the locking convex point 3 .

[0057] Furthermore, a plurality of locking recesses 13 are provided at the bottom of the rotating guide ring 12, and the locking protrusions 3 can be stuck in the locking recesses 13, so that if the user does not actively rotate the probe body by dialing the key 5, the probe body can be locked in one position and does not rotate.

[0058] The depth of the rotating guide ring 12 is smaller than the height of the locking protrusion 3 .

[0059] Furthermore, the depth of the rotating guide ring 12 is smaller than the height of the locking protrusion 3, and the depth of the rotating guide ring 12 plus the locking protrusion 3 is greater than or equal to the height of the locking protrusion 3, so that the locking protrusion 3 will be stuck in the locking recess 13 without the user's active rotation.

[0060] A plurality of locking recesses 13 form different rotation gears to meet various rotation angle requirements.

[0061] The rotating groove 8 is also connected with a positioning pin 11 , which is located outside the rotating guide ring 12 .

[0062] like Figure 4 As shown, the positioning pin 11 is located on the outward rotation path of the plug part 4, blocking the dial key 5 to prevent over-rotation. In the figure, the plug part 4 rotates clockwise from top to left, and the positioning pin 11 is located on the bottom edge of the rotation groove 8, blocking the dial key 5 to prevent over-rotation.

[0063] A method for using a position-adjustable fuel cell voltage inspection socket.

[0064] Insert the rotating part 1 of the probe body into the rotating pin 10, align the locking protrusions 3 on both sides with the rotating guide rings 12 of the cathode plate 7 and the anode plate 6, extend the dial key 5 out of the probe slot, and install the cathode plate 7 and the anode plate 6;

[0065] When in use, the probe body is rotated around the rotating pin 10 through the exposed dial key 5, so that the plug part 5 is exposed and connected with the slots of other components;

[0066] When not in use, the probe body is rotated around the rotating pin 10 through the exposed dial key 5, so that the plug part 5 is rotated into the plug slot 9. Only the dial key 5 of the entire probe is exposed to the outside, thereby preventing the plug part 5 from being scratched and damaged.

[0067] When in use, first install the probe body in the probe slot, align the rotating hole 2 with the pin slot, put the plug part 4 into the plug slot 9, align the locking protrusion 3 with the rotating guide ring 12, and then install the cathode plate 7 and the anode plate 6 together. At this time, except for the dial key 5, the other structures of the probe body are all inside the battery cell (i.e., the cathode plate 7 and the anode plate 6).

[0068] like Figure 8 As shown, when in use, the probe body is rotated by the dial key 5 so that the plug part 4 is rotated out clockwise and aligned with the connector for connection;

[0069] like Figure 7 As shown, when not in use, the probe body is rotated by the dial key 5 so that the plug portion 4 rotates counterclockwise back into the probe slot to avoid scratches and damage during transportation and assembly.
