[0030] The following is the specific embodiment of the utility model and is combined with the drawing, and the technical scheme of the utility model is further described, but the utility model is not limited to these embodiments.

[0031] Example 1

[0032] like Figures 1-5 As shown, a battery temperature sensor installation and positioning structure includes a mounting plate 1 and a positioning bracket 2. The temperature sensor 4 is movably arranged on the mounting plate 1 through the positioning bracket 2, so as to avoid the battery cell 5 during installation and fit with the pole ear 51 of the battery cell 5.

[0033] Specifically, the battery cell 5 can be inserted and installed on one side of the mounting plate 1 to form a complete battery. A avoidance portion is provided on the mounting plate 1, and the positioning bracket 2 is movably installed in the avoidance portion. The temperature sensor 4 is fixed on the positioning bracket 2, and the temperature sensor 4 can move with the positioning bracket 2, and its position can change. Therefore, the temperature sensor 4 can rotate with the positioning bracket 2 until it is retracted in the avoidance portion. At this time, the battery cell 5 can be inserted and installed. Since the temperature sensor 4 is located in the avoidance portion, the battery cell 5 can be avoided to prevent the battery cell 5 from scratching the temperature sensor 4. After the battery cell 5 is installed, the temperature sensor 4 can extend from the avoidance portion and fit with the tab of the battery cell 5 to detect the tab temperature of the battery cell 5. Since the moving path of the positioning bracket 2 is fixed, the path of the temperature sensor 4's rotation is also fixed, which can improve the fitting accuracy between the temperature sensor 4 and the tab 51 of the battery cell 5, thereby improving the detection accuracy of the temperature sensor 4.

[0034] Specifically, the avoidance portion is set as a groove 11, and the first adapter portion is provided on the two opposite inner walls of the groove 11. The second adapter portion is provided on the two legs 21 of the positioning bracket 2. The second adapter portion is rotatably connected to the first adapter portion. The rotational connection between the positioning bracket 2 and the mounting plate 1 can be realized through the cooperation between the second adapter portion and the first adapter portion, that is, the positioning bracket 2 is rotatably connected to the mounting plate 1, and it drives the temperature sensor 4 to adjust its position through rotation.

[0035] In this embodiment, the position adjustment of the temperature sensor 4 is achieved by rotating the positioning bracket 2, thereby achieving the avoidance of the temperature sensor 4 to the battery cell 5 and the fit between the temperature sensor 4 and the tab 51 of the battery cell 5. Of course, the position adjustment of the temperature sensor 4 can also be driven by other methods, such as translation and sliding, which should not exceed the scope of the record of this application.

[0036] In this embodiment, in order to facilitate the rotation of the positioning bracket 2 and avoid the bottom of the groove 11 interfering with the positioning bracket 2, the groove 11 is entirely configured as a through groove, that is, the groove 11 can pass through both sides of the mounting plate 1.

[0037] Specifically, the first adapter is a positioning rod 12, two positioning rods 12 are symmetrically arranged on the two inner walls opposite to the groove 11, the second adapter is a positioning hole 211, one end of the positioning rod 12 is rotatably inserted into the positioning hole 211, then the positioning support 2 can rotate around the positioning rod 12 through the supporting leg 21, and further drive the temperature sensor 4 to rotate, after rotating a preset angle, the positioning of the positioning support 2 and the temperature sensor 4 can be realized through the cooperation of the positioning hole 211 and the positioning rod 12, so as to avoid automatic rotation, and further to ensure that the temperature sensor 4 is always in contact with the tab of the battery cell 5.

[0038] Among them, in order to realize the connection of the two supporting legs 21 and the two positioning rods 12, the two supporting legs 21 can be compressed inwardly first, so that the two positioning rods 12 are inserted into the two positioning holes 211, and then the two supporting legs 21 are loosened to automatically reset.

[0039] In order to realize the rotational positioning of the positioning support 2, the positioning rod 12 is provided as a polygonal rod, and the positioning hole 211 is provided as a polygonal hole matched with the positioning rod 12, so that when the positioning rod 12 is inserted into the positioning hole 211, the inner wall of the positioning hole 211 can be in contact with the outer wall of the positioning rod 12 to form a clamping of the positioning rod 12, which can prevent it from rotating automatically under the action of external force, thereby limiting the automatic rotation of the positioning support 2, and under the action of the force applied by the operator, the positioning support 2 can be driven to rotate, and when the positioning hole 211 is rotated to a preset angle and the edge of the positioning hole 211 is in contact with the edge of the positioning rod 12, the position of the positioning support 2 is fixed at this position once the action force is stopped, realizing the automatic positioning, and ensuring that the temperature sensor 4 can be in contact with the tab 51 of the battery cell 5.

[0040] In the present embodiment, the positioning rod 12 is provided as a quadrilateral rod, the positioning hole 211 is provided as a quadrilateral hole, and the positioning rod 12 is provided with a guide slope 121 between the two adjacent sides, so that the positioning support 2 is rotated by a preset angle of 90°, 180°, 270° and 360°, and each rotation of 90° can be pre-positioned, and one of the positions can be set as the position where the temperature sensor 4 is in contact with the tab of the battery cell 5, so that the automatic positioning can be realized at this position, wherein the guide slope 121 between the two adjacent sides of the positioning rod 12 plays a role in transition of rotation, avoiding the positioning support 2 and the positioning rod 12 from being stuck.

[0041] In order to realize the rotation of the positioning support 2, the positioning hole 211 is required to have a certain elastic deformation capacity, and therefore a clamping portion 212 in the shape of a barb is arranged at the bottom of the supporting leg 21, the clamping portion 212 and the supporting leg 21 jointly form the positioning hole 211, one end of the clamping portion 212 is connected to the bottom end of the supporting leg 21, and the other end of the clamping portion 212 is located at one side of the supporting leg 21, that is, the positioning hole 211 is arranged as a broken hole, when the positioning rod 12 presses the clamping portion 212, the one end of the clamping portion 212 is driven to move away from the side of the supporting leg 21, the positioning hole 211 is expanded, so that the positioning support 2 can rotate, after rotating to a preset angle, the positioning rod 12 no longer presses the clamping portion 212, at this time, the clamping portion 212 automatically resets, the one end of the clamping portion 212 moves towards the side of the supporting leg 21, the positioning hole 211 is reduced, and the positioning rod 12 is clamped.

[0042] Of course, in addition to the positioning hole 211 being arranged as a broken hole as mentioned in the embodiment, the material of the clamping portion 212 can also be arranged as an elastic material, which can also have the effect of elastically clamping the positioning rod 12, or other elastic clamping modes can be adopted, which should not exceed the scope of the present application.

[0043] In order to facilitate the insertion of the positioning rod 12 into the positioning hole 211, the positioning rod 12 has a first end 122 fixed to the mounting plate 1 and a second end 123 that can be inserted into the positioning hole 211, the size of the second end 123 is smaller than the size of the first end 122, specifically, the length of the side of the second end 123 is smaller than the length of the side of the first end 122, and the width of the side of the second end 123 is smaller than the width of the side of the first end 122, so that the second end 123 is easily inserted into the positioning hole 211 during the insertion process, until the inner wall of the positioning hole 211 completely covers the outer side of the positioning rod 12, which facilitates the insertion of the positioning rod 12 while achieving the positioning of the positioning support 2.

[0044] In the embodiment, a smooth transition mounting slope is arranged between the first end 122 and the second end 123 of the positioning rod 12, during assembly, the mounting slope of the positioning rod 12 gradually contacts the inner wall of the positioning hole 211 when the positioning rod 12 is inserted into the positioning hole 211, until the inner wall of the positioning hole 211 completely covers the positioning rod 12, and the positioning rod 12 cannot be further inserted, which realizes the quick and rapid assembly of the positioning rod 12 and the positioning rod 12.

[0045] Of course, the positioning rod 12 can also be arranged in a stepped manner, for example, the positioning rod 12 is divided into a first portion, a second portion and a third portion arranged along the first end to the second end, wherein the cross-sectional length of the first portion is greater than the cross-sectional length of the second portion, the cross-sectional width of the first portion is greater than the cross-sectional width of the second portion, the cross-sectional length of the second portion is greater than the cross-sectional length of the third portion, and the cross-sectional width of the second portion is greater than the cross-sectional width of the third portion, which also has the effect of reducing the size and facilitating the insertion of the positioning rod 12.

[0046] In order to monitor the temperature of the tab of the battery cell 5 in real time, an FPC acquisition board 3 is further included, which is fixed on the mounting plate 1 and is electrically connected with the temperature sensor 4. When the temperature sensor 4 measures the temperature of the tab 51 of the battery cell 5, the temperature is transmitted to the FPC acquisition board 3 through an electrical signal, and the FPC acquisition board 3 transmits the collected signal to the control system, so that the control system determines whether the temperature of the tab 21 is within a normal range.

[0047] Embodiment two

[0048] In this embodiment, the positioning rod is a pentagonal rod, the positioning hole is a pentagonal hole, and a guide slope is arranged between two adjacent side edges of the positioning rod. Similarly, the guide slope also facilitates the rotation of the positioning support. Since the positioning rod is a pentagonal rod and the positioning hole is a pentagonal hole, 360 degrees can be equally divided into five parts, i.e., 72 degrees, 144 degrees, 216 degrees, 288 degrees and 360 degrees. In addition, the positioning rod can be a hexagonal rod, the positioning hole can be a hexagonal hole, and the rotation angle of the positioning support can also be re-divided. The rotation angle is determined according to the position of the temperature sensor and the tab of the battery cell.
