As shown in fig. 1, the present embodiment provides a vehicle battery cooling assembly 10 including at least a temperature sensor 1, a battery cooling plate 2, and a sensor mounting bracket 3 as shown. In this embodiment, the temperature sensor 1 is mounted on the battery cooling plate 2 by designing a novel sensor mounting bracket 3.

In the present embodiment, the temperature sensing end 11 of the temperature sensor 1 is fixed at a preset position on the surface of the battery cooling plate 2 by the sensor mounting bracket 3 so that the temperature sensing end 11 can detect the temperature data of the battery cooling plate 2 at the position and transmit the temperature data to the electronic device in communication with the output end 13 of the temperature sensor 1 through the wire harness 12 of the temperature sensor 1.

In a practical application scenario, the battery cooling plate 2 generally needs to be detected at a position of real-time temperature, for example: and the temperature data of the cooling plate positions are acquired at the cooling liquid inlet position, the cooling liquid outlet position and the like, so that the external electronic equipment is beneficial to accurately controlling the temperature of the battery cooling plate 2, and further is beneficial to accurately controlling the temperature of the battery module which is in contact with the battery cooling plate 2 and performs heat exchange.

The foregoing electronic devices include, but are not limited to: data input/output and data processing equipment such as car computers, desktop computers, portable computers, tablet computers, smart phones and the like.

As shown in fig. 2, the sensor mounting bracket 3 of the present embodiment includes: a connection portion 31 and a housing portion 32.

Specifically, the connecting portion 31 in the present embodiment includes left and right flat plate structures, and may be fixed to the base surface of the battery cooling plate 2 by caulking, welding, or the like. The accommodating portion 32 is located between the left and right connecting portions 31 and is connected to the left and right connecting portions 31, respectively. In a state where the left and right connection portions 31 are connected to the battery cooling plate 2, the accommodation portion 32 and the surface of the battery cooling plate 2 together constitute an accommodation space accommodating and restricting the temperature sensor 1.

The structure of the temperature sensor mounting bracket 3 of the present application will be described in detail below with reference to the accompanying drawings.

For convenience of description, hereinafter, a longitudinal direction perpendicular to the temperature sensor 1 is defined as a first direction X, a longitudinal direction of the temperature sensor 1 is defined as a third direction Y, the battery cooling plate 2 is located on a plane in which XY is located, and a direction perpendicular to the battery cooling plate 2 is defined as a second direction Z.

In the present embodiment, the accommodating space formed by the temperature sensor mounting bracket 3 and the battery cooling plate 2 accommodates and limits the temperature sensing end 11 of the temperature sensor 1. However, the present application is not limited thereto, and the temperature sensor mounting bracket 3 may be designed to accommodate a portion of the temperature sensing end or to accommodate all of the temperature sensing end and a portion of the wire harness connected to the temperature sensing end in practical applications.

As shown in fig. 2, the accommodating portion 32 of the present embodiment includes two groove portions: the

groove portions

34a and 34b, but in other embodiments there may be only one, three, or more than three groove portions, which is not limited in this application.

The groove 34a has left and right first side walls 341, and top walls 342 connected to the left and right first side walls 341, respectively, and the left and right first side walls 341 are connected to the left and right connecting portions 31, respectively. Preferably, the left and right first side walls 341 are perpendicular to the plane of the battery cooling plate 2, and the top wall 342 is parallel to the plane of the battery cooling plate 2.

In the present embodiment, the left and right first side walls 341 are connected to the left and right connecting portions 31 through left and right chamfer surfaces 340, respectively. The chamfer 340 has a certain angle with the battery cooling plate 2, and the space of the angle can be used for stacking the brazing layer composite material melted by the temperature sensor mounting bracket 3 during brazing, so as to prevent the part of the composite material from flowing into the accommodating space, and further avoid adverse effects on the subsequent insertion of the temperature sensing end 11.

As shown in fig. 2, the groove 34a is located at the rear of the temperature sensor mounting bracket 3, the groove 34b is located at the head of the temperature sensor mounting bracket 3, and the temperature sensing end 11 passes through the groove 34b before entering the groove 34a when being inserted into the accommodating portion 32.

Referring to fig. 3, in the present embodiment, the slot 34a is further provided with a limiting surface 344, which is located at an end of the slot 34a away from the slot 34b and extends from the top wall 342 in a direction away from the top wall 342, compared to the slot 34 b. Preferably, the limiting surface 344 is perpendicular to the top wall 342 and the first side wall 341, respectively. When the temperature sensing end 11 is inserted into the accommodating portion 32, the end surface 112 thereof is blocked by the limiting surface 344, so that the temperature sensing end 11 does not pass through the accommodating portion 32.

In other embodiments, the limiting surface 344 may be disposed at other positions of the groove 34a, such as the inner side of the first side wall, the lower surface of the top wall, etc., and the specific position may be determined according to the actually required depth of the temperature sensing end to be inserted into the accommodating space, which is not limited in this application.

As shown in fig. 2, in the present embodiment, left and right tooth pieces 352 that can be bent are further provided between the

groove portions

34a and 34 b. The temperature sensing end 11 has a recess 111 extending in the first direction X.

Specifically, the receiving portion 32 further includes left and right second side walls 351. The bottom edges of the left and right second side walls 351 are respectively connected to the left and right connection portions 31, more specifically, to the left and right connection portions 31 through the left and right chamfer surfaces 340. The left and right sides of the left second side wall 351 are connected to the left first side walls 341 of the

groove

34a and 34b, respectively, and the left and right sides of the right second side wall 351 are connected to the right first side walls 341 of the

groove

34a and 34b, respectively.

The top edges of the left and right second side walls 351 are provided with teeth 352 which can be bent. As shown in fig. 3, after the temperature sensing end 11 is inserted into the accommodating space along the third direction Y and limited by the limiting surface 344, the left and right tooth plates 352 correspond to the positions of the grooves 111. Referring to fig. 2, a width a of each tooth 352 in the third direction Y matches a width B of the groove 111 of the temperature sensing end 11 in the third direction Y. Referring to fig. 3, in the present embodiment, the left and right tooth plates 352 are respectively bent 90 ° toward the groove 111 to be embedded in the groove 111, so that the temperature sensor mounting bracket 3 and the temperature sensing end 11 are limited in the first direction X, the second direction Z and the third direction Y.

The height of the left and right teeth 352 in the second direction Z should be smaller than the length of the groove 111 in the first direction X, so as to ensure that the free ends of the left and right teeth 352 have a certain distance therebetween without blocking each other after being bent.

It should be noted that, in other embodiments, the effect that the temperature sensor mounting bracket 3 and the temperature sensing end 11 are limited to each other in three directions can be achieved without bending the left and right tooth plates 352 by 90 ° toward the groove 111. In detail, when the left and right teeth 352 are respectively bent toward the inside of the groove 111, the left and right sides of each tooth 352 may be partially embedded in the groove 111.

In the present embodiment, the sensor mounting bracket 3 is an integrally formed structure. As shown in fig. 3, the top wall 342 may be provided with a positioning hole 343, and the shape thereof may be arbitrarily set. The positioning holes 343 can facilitate the positioning of the temperature sensor mounting bracket 3 at the exact position on the battery cooling plate 2 when the temperature sensing end 11 needs to be inserted into the receiving space.

The procedure for assembling the temperature sensor 1 and the battery cooling plate 2 is as follows:

first, the connection portion 31 of the sensor mounting bracket 3 is fixed to a preset position of the battery cooling plate 2; for example, the connecting portion 31 is riveted and then welded to the coolant inlet, the coolant outlet, or the like of the battery cooling plate 2;

then, the temperature sensing end 11 of the temperature sensor 1 is inserted into the accommodation space formed by the accommodation portion 32 of the sensor mounting bracket 3 and the surface of the battery cooling plate 2 together:

finally, the tooth 352 of the sensor mounting bracket 3 is bent into the groove 111 of the temperature sensing end 11 by a certain angle, including but not limited to 90 °, so that the bent tooth 352 is at least partially embedded in the groove 111, thereby realizing the limit of the tooth 352 and the groove 111 to each other in the first direction X, the second direction Z and the third direction Y.

In addition, the present application provides a vehicle, in particular a new energy vehicle, comprising a vehicle battery cooling assembly 1O as described above, which is not repeatedly developed here.
