[0034] Example

[0035] like Figures 1 to 5 As shown, a positionable installation fixture is suitable for positioning and installing a carrier plate 5 and an adapter plate 6 of a battery, including a cover plate 1 and a pressure block 2 that cooperate with each other, the cover plate 1 is provided with a mounting groove 11, and the pressure block 2 is provided with a mounting hole 21, and the mounting groove 11 and the mounting hole 21 are both installed with attractive magnetic blocks 3, and the cover plate 1 is provided with positioning holes at four corners and at least one side, and each positioning hole is fixedly installed with a positioning pin 4, and the positioning pin 4 passes through the pressure block 2 so that the pressure block 2 can move along the positioning pin 4.

[0036] Specifically, including but not limited to, the cover plate 1 is set as a rectangular structure, the mounting groove 11 is set at the bottom of the corresponding part of the cover plate 1 and the pressing block 2, and there are two mounting grooves 11, each mounting groove 11 is embedded with a magnet, the pressing block 2 is set as a rectangular block, and the mounting hole 21 is set at the corresponding part of the pressing block 2 and the mounting groove 11, so that when the cover plate 1 is connected to the pressing block 2, the mounting groove 11 is connected with the mounting hole 21, and there are also two mounting holes 21, and at this time, a magnet is also embedded in the mounting hole 21 , and the mounting groove 11 is attracted to the magnet in the mounting hole 21, so as to realize the fixed connection between the cover plate 1 and the pressure block 2. In addition, the cover plate 1 is provided with a fixing structure that is engaged with the positioning pin 4. Then, one end of the positioning pin 4 is fixed to the cover plate 1, and the positioning pin 4 passes through the pressure block 2. At the same time, under the mutual adsorption of the magnets, the pressure block 2 can move up and down along the positioning pin 4. The positioning pin 4 also plays a guiding role in the movement of the pressure block 2. The four corners of the cover plate 1 and the sides corresponding to the pressure block 2 are fixedly installed with positioning pins 4.

[0037] It is worth noting that: Figure 2 As shown, when the jig of the present application is used in practice, the carrier plate 5 and the adapter plate 6 are provided with through holes corresponding to the positioning holes 15 at the four corners and one side of the cover plate 1, and the through holes and the positioning holes 15 are arranged in the same straight line in the vertical direction, which is convenient for the positioning of the positioning pin 4. In this embodiment, the four corners of the cover plate 1 and the side in contact with the pressing block 2 are provided with positioning holes 15, so the carrier plate 5 and the adapter plate 6 are also provided with multiple through holes, and the adapter plate 6 is provided with multiple positioning posts, and the through holes are opened in the positioning posts. Based on this, multiple positioning pins 4 can pass through and fix the carrier plate 5, and then the other end of the positioning pin 4 is inserted into the through hole of the adapter plate 6, so that the carrier plate 5 and the adapter plate 6 can be positioned and connected by the jig of the present application. At the same time, the carrier plate 5 is loaded with a battery management system, and the adapter plate 6 is loaded with a battery module.

[0038] Through the above scheme, the cover plate 1, the pressing block 2 and the positioning pin 4 cooperate with each other, so that the pressing block 2 can move along the positioning pin 4, and the positioning pins 4 at the four corners and sides of the cover plate 1 can pass through the through holes of the carrier plate 5 and the adapter plate 6 in turn, so as to realize the precise positioning of the multi-hole positions, and then the pressing block 2 is pressed down until it fits with the carrier plate 5, and the connectors such as the double-row pins passing through the carrier plate 5 can be accurately inserted into the adapter plate 6, thereby ensuring the quality of the battery management system and improving the installation efficiency and service life.

[0039] As an improved specific implementation, the cover plate 1 includes a cross bar 12 and a vertical bar 13 fixedly connected to the cross bar 12 , at least two cross bars 12 and two vertical bars 13 are provided, and one end of the vertical bar 13 extends through the cross bar 12 to form a protrusion 14 .

[0040] Specifically, including but not limited to, the cross bar 12 and the vertical bar 13 are both configured as rectangular bars, two cross bars 12 are provided and are parallel to each other, three vertical bars 13 are provided and are parallel to each other, the cross bar 12 and the vertical bars 13 are perpendicular to each other, and one end of the three vertical bars 13 is fixedly connected to one of the cross bars 12, and the other end of the three vertical bars 13 passes through another cross bar 12 and partially extends to form three protrusions 14, and the three protrusions 14 are respectively provided at the center and both ends of the cross bar 12, that is, the three vertical bars 13 are respectively provided at the two ends and the center of the cross bar 12, and the three protrusions 14 all protrude from the same side of the cross bar 12. Of course, in this embodiment, the vertical bars 13, the cross bar 12 and the protrusions 14 are configured as an integrated structure, which is convenient for the production of the cover plate 1 in the early stage. In some embodiments, the pressing block 2, the vertical rod 13 and the cross rod 12 can be set as a split structure. In this case, only two cross rods 12 and two vertical rods 13 are required to be detachably assembled and assembled into a rectangular frame with a hollow middle. Then, multiple protrusions 14 are installed on the side of one of the cross rods 12 with multiple holes, and the protrusions 14 are provided with corresponding holes, so that the cross rod 12 and the protrusions 14 can be fixed. In this way, it can be adjusted according to the through holes of different sizes of the supporting plate 5 and the adapter plate 6, and the number of protrusions 14 can be increased or decreased according to needs. Whether the above-mentioned cross rod 12, vertical rod 13 and protrusion 14 are of integrated or split structure, the mounting groove 11 is arranged at the bottom of the corresponding part of the pressing block 2.

[0041] Through the above solution, the cross bar 12, the vertical bar 13 and the plurality of protrusions 14 cooperate, and the plurality of positioning pins 4 are fixedly mounted on the cover plate 1, and the multi-hole positions are positioned simultaneously, thereby ensuring the stability and accuracy of the fixture positioning.

[0042] As an improved specific implementation, part of the positioning hole 15 is provided on the protrusion 14 , and the positioning pin 4 is inserted into the positioning hole 15 and fixed, so that the positioning pin 4 is engaged with the cover plate 1 .

[0043] Specifically, including but not limited to, some positioning holes on the cover plate 1 corresponding to the pressure block 2 are set on the protrusion 14, a hollow cylindrical rod is set in the positioning hole 15, and a hole is opened on the top of the positioning pin 4. At this time, the diameter of the hole is larger than the cylindrical rod. During installation, the positioning pin 4 can be directly inserted into the protrusion 14 so that the cylindrical rod and the hole are socketed, thereby fixing the positioning pin 4. When the positioning pin 4 needs to be replaced, it only needs to be pulled out from the cylindrical rod. At the same time, positioning holes 15 are also set at both ends of the cross bar 12 of the cover plate 1 away from the pressure block 2.

[0044] Through the above solution, the detachable connection between the positioning pin 4 and the cover plate 1 can replace the positioning pin 4 of different sizes according to needs, and the positioning pin 4 is fixedly installed in the positioning hole 15, thereby improving the adaptability of the fixture.

[0045] As an improved specific implementation, a groove 131 is provided at a portion of the vertical rod 13 close to the pressing block 2 , and the groove 131 is provided along the length direction of the vertical rod 13 ; the height of the groove 131 corresponds to the thickness of the pressing block 2 .

[0046] Specifically, including but not limited to, the vertical rods 13 respectively connected to the two ends of the cross rod 12 are provided with grooves 131, and the grooves 131 are oriented vertically downward, and the grooves 131 are opened along the entire top surface of the vertical rod 13 in the length direction. The specific opening length of the grooves 131 can be set according to actual needs. On the one hand, it can improve the distance between the vertical rod 13 and the supporting plate 5 to avoid scratches when the fixture is used. On the other hand, the height of the grooves 131 corresponds to the thickness of the pressing block 2, so that when the pressing block 2 is in contact with the bottom surface of the cover plate 1, the lower surface of the pressing block 2 and the lower surface of the cover plate 1 are on the same straight line.

[0047] Through the above solution, the arrangement of the groove 131 can keep the bottom surface of the cover plate 1 at a uniform level after the pressing block 2 is installed, avoiding one end being higher than the other end when the fixture is positioned and fixed, thereby ensuring the accurate positioning of the fixture.

[0048] As an improved specific implementation, the pressing block 2 is further provided with a connecting hole 22, which corresponds to the positioning hole 15 of the protrusion 14, so that the positioning needle 4 passes through the positioning hole 15 and the connecting hole 22 in sequence, and the diameter of the positioning needle 4 is smaller than the diameter of the connecting hole 22.

[0049] Specifically, including but not limited to, the connection holes 22 are set through along the thickness direction of the pressing block 2, and each positioning hole 15 is correspondingly provided with a connection hole 22. In this embodiment, there are 3 connection holes 22 on the pressing block 2. At this time, the positioning pin 4 can be fixedly installed with the cover plate 1, and the cover plate 1 and the pressing block 2 are fitted under the action of the magnetic block 3, and the positioning pin 4 passes through the connection hole 22. At this time, part of the positioning pin 4 protrudes from the lower plane of the pressing block 2, and the diameter of the positioning pin 4 is smaller than the diameter of the connection hole 22; of course, in some embodiments, in order to cooperate with the detachable structure of the above-mentioned protrusion 14 and the cross bar 12, the number of connection holes 22 can also be set on the pressing block 2 according to needs, so that it can be adjusted according to the size of the carrier plate 5 actually loaded with the battery management system. As the installation position of the protrusion 14 is adjusted, the positioning hole 15 and the connection hole 22 can still correspond.

[0050] Through the above scheme, the positioning pin 4 passes through the connecting hole 22, so that the pressing block 2 can move along the positioning pin 4. At the same time, when there is no pressure, the pressing block 2 can move up along the positioning pin 4 under the adsorption force of the magnet until the pressing block 2 fits with the cover plate 1, thereby ensuring the practicality of the fixture.

[0051] As an improved specific embodiment, the positioning needle 4 includes a front section 41, a middle section 42 for fixing the supporting plate 5 and a rear section 43 for fixing the adapter plate 6 which are connected to each other in sequence, and the front section 41 is fixedly connected to the cover plate 1; the diameters of the front section 41, the middle section 42 and the rear section 43 decrease in sequence; the middle section 42 is an arc-shaped structure with a gradually decreasing diameter.

[0052] Specifically, including but not limited to, the positioning pin 4 is set to a conical structure, at this time, the cylindrical end of the front section 41 can be connected with the mounting groove 11 of the cover plate 1 and fixed, the middle section 42 is set to an arc structure with a gradually decreasing diameter, which can be inserted into the through hole and fixed after the bearing plate 5 is fixed, and the conical end of the rear section 43 can be directly inserted into the through hole of the positioning tooth column set in the adapter plate 6 and fixed, and the positioning tooth column corresponds to and is connected to the through hole of the bearing plate 5, so that the cover plate 1, the pressure block 2, the bearing plate 5 and the adapter plate 6 can be positioned and connected from top to bottom. Of course, the specific length of the positioning pin 4 can be set according to actual needs. At the same time, a spacing is set between the bearing plate 5 and the cover plate 1. The length of this spacing is greater than the thickness of the pressure block 2 to ensure that the pressure block 2 can move up and down.

[0053] Through the above scheme, the setting of the positioning pin 4 can position and connect the cover plate 1, the pressure block 2, the supporting plate 5 and the adapter plate 6 in sequence, and can also play a guiding role. When the pressure block 2 is pressed down, the cover plate 1 only needs to be slightly lifted to loosen the supporting plate 5 from the positioning pin 4 without pulling up the supporting plate 5 again, which is more suitable for actual production operations.

[0054] How it works:

[0055] First, the magnets that attract each other are installed in the mounting groove 11 and the mounting hole 21 respectively, and then the front sections 41 of the plurality of positioning pins 4 are fixed to the plurality of positioning holes 15 at the four corners and one side of the cover plate 1 to achieve the fixation and preliminary positioning of the positioning pins 4. Then, the pressing block 2 and the cover plate 1 are fitted together under the action of the magnetic block 3, and the positioning pins 4 pass through the connecting holes 22 of the pressing block 2, so that the cover plate 1 and the pressing block 2 are fixedly connected, thereby completing the assembly of the jig of the present application. Finally, the positioning pins 4 are used to pass through the through holes of the carrier plate 5 to achieve the positioning and fixing of the carrier plate 5. The middle section 42 of the positioning pin 4 is then inserted into the through hole of the positioning tooth column on the adapter plate 6 using the rear section 43 of the positioning pin 4, so that the adapter plate 6, the carrier plate 5 and the jig of the present application can achieve multi-hole positioning. After the positioning is completed, the pressure block 2 is pressed hard, and the pressure block 2 moves downward along the positioning pin 4, so that the double-row pins of the carrier plate 5 are inserted into the adapter plate 6 for connection. Based on this, when the pressure block 2 is pressed close to the upper surface of the carrier plate 5, the double-row pins are connected. At this time, you only need to slightly lift the cover plate 1 to loosen the carrier plate 5 from the positioning pin 4.

[0056] Finally, it should be noted that the above is only the preferred implementation of the utility model, and the protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
