DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0020] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0021] like Figure 1-Figure 2 As shown, the present invention provides a multi-series-parallel public mold bracket with an NTC bracket, including: an NTC bracket 1, connected between a first bracket 2 and a second bracket 3, the first bracket 2 and the second bracket 3 are used to install a plurality of battery cells 4, and an installation space 7 for accommodating the NTC bracket 1 is formed between adjacent battery cells 4.

[0022] When assembling the battery module, first assemble the second bracket 3, the NTC bracket 1 and the multiple battery cells 4, and apply thermal conductive silicone on the NTC bracket 1. The NTC bracket 1 is placed in the installation space 7. The thermal conductive silicone is used to fix the NTC temperature sensor 10. Then assemble the first bracket 2 and the nickel sheet 24, and then assemble the NTC temperature sensor 10 on the NTC bracket 1. Use tape to fix the part of the NTC temperature sensor 10 that is not installed with the NTC bracket 1. Finally, fix the BMS circuit board 22 with the double-sided tape 23, and electrically connect the NTC temperature sensor 10 to the BMS circuit board 22.

[0023] Through the above scheme, the NTC bracket 1 can be limited between multiple battery cells 4, so that the NTC temperature sensor 10 installed thereon can be close to the surface of the battery cell 4, thereby improving the detection accuracy of the NTC temperature sensor 10 for the battery module temperature; and, the NTC bracket 1 utilizes the space and structure of the original battery module, so that the NTC bracket 1 can be connected to the first bracket 2 and the second bracket 3, thereby ensuring the stability of the installation of the NTC temperature sensor 10.

[0024] like Figure 3 and Figure 4 As shown, in one embodiment, the NTC bracket 1 includes: a bracket body 5, used to limit the NTC temperature sensor 10 in the installation space 7; and clamping parts 6 arranged at both ends of the bracket body 5, and the two clamping parts 6 are respectively clamped with the first bracket 2 and the second bracket 3.

[0025] The bracket body 5 is used to install the NTC temperature sensor 10 , and the two clamping parts 6 can be clamped with the first bracket 2 and the second bracket 3 respectively to achieve a limited connection to the NTC bracket 1 , which can ensure the installation stability of the NTC temperature sensor 10 .

[0026] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, in one embodiment, the clamping portion 6 includes: a column, on which a clamping ring 62 is provided, and a surface of the clamping ring 62 away from the bracket body 5 is a conical surface, and a groove 63 is provided on the column, and the groove 63 extends along the axis of the column to divide the column into two clamping columns 61; The first bracket 2 and the second bracket 3 are both provided with a stepped hole 21 corresponding to the clamping portion 6 , and the diameter of one end of the stepped hole 21 close to the bracket body 5 is smaller than the diameter of the other end thereof.

[0027] Furthermore, the inner top or inner bottom of the hole with a small diameter of the stepped hole 21 is a plane, and the top and bottom of the column are also set to corresponding planes. After the column is inserted into the stepped hole 21, the column can be limited to prevent the column from rotating, thereby realizing the positioning and clamping of the NTC bracket.

[0028] The clamping portion 6 is clamped with the stepped hole 21, and the clamping portion 6 is inserted from the end of the stepped hole 21 with a smaller diameter, squeezing the clamping ring 62 so that the two clamping columns 61 are close to each other. When the clamping ring 62 is inserted to the end of the stepped hole 21 with a larger diameter, the two clamping columns 61 are restored, and the clamping ring 62 and the stepped hole 21 are clamped, and the two ends of the bracket body 5 are respectively abutted against the first bracket 2 and the second bracket 3.

[0029] The design of the stepped hole 21 is an improvement on the local structure based on the original structure of the first bracket 2 and the second bracket 3, that is, the local structure where the stepped hole 21 is located, and the rest of the structure does not need to be changed and can still be used.

[0030] like Figure 3 and Figure 5 As shown, in one embodiment, four protrusions 51 corresponding to the installation space 7 are formed on the surface of the bracket body 5, and a concave arc surface 52 is formed between two adjacent protrusions 51; a first cutout 53 is provided on one of the protrusions 51 along its length direction, and a guide groove 54 is provided at the first cutout 53; a guide hole 55 connected to the guide groove 54 is provided at one end of the bracket body 5 away from the first cutout 53, and the guide hole 55 passes through a clamping portion 6; the NTC temperature sensor 10 is inserted into the guide hole 55 and guided by the guide groove 54, and extends to the outside of the guide groove 54.

[0031] The four protrusions 51 and the four arc-shaped surfaces 52 are designed according to the installation space 7 so that the bracket body 5 can be inserted into the installation space 7. The first cutout 53 is provided to leave a protruding space for the front end of the NTC temperature sensor 10 to prevent the NTC temperature sensor 10 from being stuck in the guide groove 54, thereby ensuring smooth installation. When installing the NTC temperature sensor 10, the front end of the NTC temperature sensor 10 is inserted from the clamping portion 6 into the guide hole 55 and then into the guide groove 54. The guide groove 54 guides the front end of the NTC temperature sensor 10 so that it extends out of the guide groove 54. The front end of the NTC temperature sensor 10, that is, its sensing end, is as follows: Figure 4 and Figure 5 At the position shown, it can be closer to the battery cell 4, better detect the temperature of the battery module when it is working, and improve the temperature detection accuracy.

[0032] like Figure 8 As shown, in one embodiment, the bottom surface of the guide groove 54 is a guide surface; The guide surface includes: a planar guide segment 56, a first arc surface guide segment 57 and a second arc surface guide segment 58 which are arranged tangentially in sequence, and the second arc surface guide segment 58 is arranged close to the guide hole 55; the first arc surface guide segment 57 is a convex setting, and the second arc surface guide segment 58 is a concave setting.

[0033] After the front end of the NTC temperature sensor 10 is inserted into the guide hole 55, it continues to move forward and moves upward under the guidance of the second arc surface guide section 58, the first arc surface guide section 57 and the plane guide section 56 in sequence, so that the front end of the NTC temperature sensor 10 extends out of the guide groove 54; The second arc surface guide section 58 is set to be concave, so that the front end of the NTC temperature sensor 10 passing through the guide hole 55 can move upward smoothly, preventing the front end from forming a movement obstacle after contacting the second arc surface guide section 58. The first arc surface guide section 57 is set to be convex, so that the front end of the NTC temperature sensor 10 will not be lifted too high after passing through the guide groove 54, preventing the front end of the NTC temperature sensor 10 from continuing to move and being inserted into a smaller gap in the installation space 7 to form a movement obstacle, thereby ensuring that the NTC temperature sensor 10 is smoothly inserted and installed.

[0034] like Figure 8 As shown, further, the arc radius of the first arc surface guide segment 57 is equal to the arc radius of the second arc surface guide segment 58, and the distance from the arc midpoint of the second arc surface guide segment 58 to the axis of the guide hole 55 is equal to the radius of the guide hole 55.

[0035] The first arc surface guide section 57 and the second arc surface guide section 58, which have equal arc radius and are smoothly connected, can form a good guiding effect on the front end of the NTC temperature sensor 10, thereby preventing the insertion of the NTC temperature sensor 10 from being hindered; The position of the arc midpoint of the second arc surface guide section 58 is set so that the contact point between the front end of the NTC temperature sensor 10 and the second arc surface guide section 58 is higher than the arc midpoint of the second arc surface guide section 58, further reducing the insertion obstacle of the NTC temperature sensor 10 and ensuring smooth installation.

[0036] like Figure 3 and Figure 5 As shown, in one embodiment, a second cutout 59 is provided on a side of the first cutout 53 away from the guide hole 55 , and a surface of the second cutout 59 is arranged lower than a surface of the first cutout 53 .

[0037] After the front end of the NTC temperature sensor 10 extending out of the guide groove 54 continues to move, it will be located at the second incision 59. The thermal conductive silicone will be pre-applied and filled in the second incision 59. When the front end of the NTC temperature sensor 10 moves to the second incision 59, it will contact the thermal conductive silicone. The thermal conductive silicone can fix the front end of the NTC temperature sensor 10 at the second incision 59, thereby fixing the NTC temperature sensor 10.

[0038] like Figure 4 and Fig. 9 As shown, in one embodiment, a thermoplastic tube 11 is sleeved on the outer side of the front end of the NTC temperature sensor 10 , and the length of the thermoplastic tube 11 is equal to the length of the NTC temperature sensor 10 installed on the NTC bracket 1 .

[0039] The front end of the NTC temperature sensor 10 is hardened by the thermoplastic tube 11, so that it is easy to be inserted and installed on the NTC bracket 1. The setting of the length of the thermoplastic tube 11 can also locate the installation position of the NTC temperature sensor 10, that is, when the NTC temperature sensor 10 is inserted into the NTC bracket 1, when the part of the NTC temperature sensor 10 wrapped by the thermoplastic tube 11 is completely inserted and installed in the NTC bracket 1, that is, Figure 5 The state shown indicates that the NTC temperature sensor 10 has been inserted into place, and further insertion is stopped.

[0040] In order to further improve the firmness of the installation between the front end of the NTC temperature sensor 10 and the NTC bracket 1, another technical solution of the NTC bracket 1 is proposed, such as Figure 10-Figure 14 As shown, a groove 12 is provided at the second cutout 59, and a plate 13 is provided in the groove 12. The plate 13 can move up and down through a lifting portion 8 provided in the groove 12; When the plate body 13 is at the lowest position, a receiving area 14 is formed between the plate body 13 and the groove 12, and the receiving area 14 is used to place the connecting colloid; wherein the connecting colloid is thermally conductive silicone; When the plate body 13 is at the highest position, at least a portion of the plate body 13 protrudes from the groove 12 , pushing the connecting colloid out to the surface of the second cutout 59 , so that the connecting colloid contacts the NTC temperature sensor 10 .

[0041] In this embodiment, a groove 12 is further provided on the basis of the structure of the aforementioned NTC bracket 1, and a plate 13 that can move up and down in the groove 12 through the lifting part 8, so that the thermal conductive silicone can be pre-filled into the accommodating area 14. In this way, when the NTC bracket 1 is inserted into the installation space 7, it can prevent the thermal conductive silicone from accidentally rubbing against the surface of the battery cell 4, resulting in the amount of thermal conductive silicone being unable to effectively fix the front end of the NTC temperature sensor 10; After the thermally conductive silicone is filled into the accommodating area 14, it can prevent the thermally conductive silicone from contacting the battery cell 4 during installation, ensuring that the amount of the thermally conductive silicone remains unchanged. Then, when the NTC temperature sensor 10 is inserted into place, the plate body 13 is lifted up by the lifting portion 8, so that at least the upper part of the plate body 13 is located outside the groove 12, and the lower part is still located in the groove 12. Then, all the thermally conductive silicone will be placed on the plate body 13 and exposed outside the groove 12, so that in the process of the plate body 13 moving upward, the thermally conductive silicone can be in close contact with the NTC temperature sensor 10. Compared with the front end of the NTC temperature sensor 10 being inserted and directly contacting the thermally conductive silicone smeared and filled on the surface of the second incision 59, the connection is more secure, preventing part of the thermally conductive silicone from being pushed forward with the insertion of the front end, resulting in a loose connection.

[0042] In addition, when the thickness of the plate body 13 is thicker, the distance that the upper portion thereof protrudes out of the groove 12 is greater, and at the same time, the front end of the NTC temperature sensor 10 can be pushed to contact the battery cell 4 , so that the NTC temperature sensor 10 is closer to the battery cell 4 .

[0043] Furthermore, it also includes: a driving part 9 for driving the lifting part 8 to move; The driving part 9 includes: a stud 91 and a push rod 92 connected to the stud 91, and the push rod 92 is coaxially arranged with the stud 91; the end of the bracket body 5 arranged near the groove 12 is provided with a through hole 15 corresponding to the push rod 92, and the clamping part 6 arranged near the groove 12 is provided with a threaded hole 16 connected with the through hole 15; by rotating the stud 91, the push rod 92 applies a pushing force to the lifting part 8, so that the lifting part 8 drives the plate body 13 to move.

[0044] A cross groove or a straight groove can be provided at one end of the stud 91 away from the push rod 92 to facilitate the screwing of the stud 91. After the NTC temperature sensor 10 is installed, the stud 91 is screwed into the threaded hole 16, and the push rod 92 is correspondingly inserted into the through hole 15, so that the push rod 92 contacts the lifting part 8. As the stud 91 is screwed in, the push rod 92 applies a driving force to the lifting part 8, so that the lifting part 8 drives the plate body 13 to move upward; in addition, after the stud 91 is screwed into place, it can support the two clamping columns 61 of the clamping part 6 to ensure the clamping stability of the clamping part 6.

[0045] Furthermore, for the lifting part 8, two structures are provided: like Fig.11 and Fig.12 As shown, it is a first structure, the lifting part 8 is a V-shaped spring piece 81, the bottom end of which contacts the bottom surface of the groove 12, one end of which is provided with a fixing piece 82, and the other end is provided with an arc-shaped supporting piece 83; the side of the groove 12 away from the driving part 9 is provided with a limiting groove 17 for limiting the fixing piece 82; when the plate body 13 is at the lowest position, the bottom surface of the plate body 13 contacts the arc-shaped supporting piece 83 and the fixing piece 82; the push rod 92 contacts one side of the spring piece 81 to push the spring piece 81 to deform, so that the arc-shaped supporting piece 83 pushes up the plate body 13.

[0046] The spring piece 81 is inserted into the limiting groove 17 through the fixing piece 82 for limiting and fixing, and then the plate body 13 is overlapped on the spring piece 81, and the arc-shaped support piece 83 and the fixing piece 82 form an initial support for it, and then the accommodating area 14 is filled with thermal conductive silicone, and then the driving part 9 is installed, and the stud 91 is screwed to make the push rod 92 contact with one side of the spring piece 81. As the push rod 92 continues to squeeze one side of the spring piece 81, the arc-shaped support piece 83 on the spring piece 81 rotates upward and pushes the plate body 13 upward, so that the plate body 13 moves upward.

[0047] like Fig.13 and Fig.14 As shown, it is a second structure, the lifting part 8 includes: two groups of hinged rods, each group of hinged rods includes a first hinged rod 84 and a second hinged rod 85 hinged in the middle, the top ends of the two first hinged rods 84 are hinged to the bottom surface of the plate body 13 through a first hinge shaft 86, the bottom ends of the two second hinged rods 85 are hinged to the bottom surface of the groove 12 through a second hinge shaft 87, the bottom ends of the two first hinged rods 84 are connected through a third hinge shaft 88, and the top ends of the two second hinged rods 85 are slidably connected to the plate body 13 through a fourth hinge shaft 89; A support block 18 is provided on the bottom surface of the plate body 13 and the bottom surface of the groove 12. A first hole is provided on the support block 18. An opening is provided on one side of the support block 18 for inserting the first hinge shaft 86 or the second hinge shaft 87. The width of the opening is smaller than the diameter of the first hole; so that the first hinge shaft 86 or the second hinge shaft 87 can be inserted and limited in the first hole after being inserted from the opening with force. The bottom surface of the plate body 13 is provided with a slide groove 19, and the end of the fourth hinge shaft 89 is protruding and can slide in the slide groove 19; The diameter of the contact portion between the third hinge shaft 88 and the push rod 92 is greater than the diameter of the connection portion between the third hinge shaft 88 and the first hinge rod 84; the setting of the third hinge shaft 88 enables it to better contact with the push rod 92; A stopper 20 is provided on the bottom surface of the groove 12, and the stopper 20 is arranged on the side of the third hinge shaft 88 close to the push rod 92; the stopper 20 can limit the position of the third hinge shaft 88 when the lifting part 8 is installed, so that the plate body 13 is stably located at the lowest position.

[0048] In the above technical scheme, the lifting part 8 is connected to the plate body 13 and the groove 12 respectively. After the connection is completed, the thermal conductive silicone is filled into the formed accommodating area 14, and then the driving part 9 is installed, and the stud 91 is screwed to make the push rod 92 contact with the third hinge shaft 88. As the stud 91 is screwed in, the push rod 92 forms a driving force on the third hinge shaft 88, so that the top end of the first hinge rod 84 pushes the plate body 13 upward, and the second hinge rod 85 moves accordingly, and the top end of the second hinge rod 85 slides relative to the plate body 13, playing a balancing and supporting role for the plate body 13; the lifting stroke of the lifting part 8 is large, and it can form a lifting effect on the plate body 13 over a large distance, thereby increasing the volume of the accommodating area 14 (the distance between the plate body 13 and the top surface of the groove 12 is increased), increasing the filling amount of thermal conductive silicone, and ensuring the connection stability of the NTC temperature sensor 10.
