The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

Example 1

The embodiment of the utility model provides the connecting row, optimizes the elastic deformation capacity of the connecting row, can enable the pole to be more conveniently connected with the connecting row in an inserting way, effectively reduces the probability that the pole cannot be inserted into the connecting row, and also effectively reduces the probability that the pole is damaged in the inserting process.

In the prior art, the deformation capability of the groove walls at the two sides of the plug-in groove on the connecting row is poor. The material of the pole is copper or copper alloy, and the strength of the pole is not high. Therefore, the situation that the two opposite side groove walls of the inserting groove are difficult to squeeze out easily occurs to the pole, namely the pole is generally difficult to be inserted into the inserting groove, even the pole is easy to deform and damage in the inserting process, and the production yield of the battery module is further affected.

Referring to fig. 1 to 8, in order to solve the above-mentioned problems, the present utility model discloses a connection bar, which has a first plugging slot 1, wherein the first plugging slot 1 has a first side slot wall, and the first side slot wall is composed of a plurality of spring plate portions 11 arranged at intervals.

In order to further reduce the difficulty of inserting the pole 71 into the first insertion groove 1, the spring piece portion 11 has an elastic connection portion 111 for connecting the bottom wall of the first insertion groove 1 and an insertion conduction portion 112 for connecting the elastic connection portion 111; the width of the elastic connection portion 111 is smaller than the width of the plug conductive portion 112 in the extending direction along the plug groove.

It should be noted that, the thickness of the elastic sheet portion 11 is substantially uniform, and the elastic connection portion 111 is easier to deform under the premise that the elastic connection portion 111 has a narrower width, so that the pole 71 can be more easily inserted into the first inserting groove 1, or the pole 71 can be more easily pulled out from the first inserting groove 1 without excessive wear, thereby being beneficial to improving the assembly efficiency of the battery module and reducing the maintenance difficulty of the battery module.

It should be noted that, the plugging conducting portion 112 is used for abutting against the pole 71 to conduct the pole 71, the width of the plugging conducting portion 112 is larger, and the abutting area between the pole 71 and the plugging conducting portion 112 is larger, so that the conducting effect is better.

Alternatively, as shown in fig. 2 and 3, the closer the elastic connection portion 111 is to the bottom wall of the first mating groove 1 in the extending direction of the mating groove, the smaller the width of the elastic connection portion 111 is, thereby further improving the elastic deformability of the elastic connection portion 111.

Optionally, the connection row further includes a second side groove wall opposite to the first side groove wall, and the first side groove wall, the second side groove wall and the bottom wall form a first insertion groove 1; a separation gap 101 is formed between two adjacent spring plate parts 11, and strip-shaped penetrating grooves 102 corresponding to the separation gaps 101 one by one are formed on the second side groove wall. The elastic sheet parts 11 are mutually separated and matched with the good elastic deformation capability of the elastic connecting part 111, so that each elastic sheet part 11 can abut against the pole 71; the plurality of bar-shaped penetrating grooves 102 divide the second side groove wall into a plurality of interference portions, so that the pole 71 can more easily interfere with the second side groove wall.

Alternatively, the spring piece portion 11 has a first protruding portion protruding toward the second side groove wall; the second side groove wall has a second protruding portion protruding toward the first side groove wall. When the pole 71 is inserted into the first inserting groove 1, the first protruding portion abuts against one side of the pole 71, and the second protruding portion abuts against the other side of the pole 71. It should be noted that, each abutting portion is provided with a second protruding portion, and the first protruding portion and the second protruding portion clamp the pole 71 in opposite directions, so that the pole 71 is fixed in the first inserting groove 1, and the pole 71 can achieve a good conducting effect with the connection row.

Optionally, the connection row further comprises a first plate portion 2, the first plate portion 2 being connected to an end of the second side channel wall remote from the bottom wall. In this embodiment, the first plate portion 2 can be used to abut against the step surface of the pole 71, so that the overall contact area between the pole 71 and the connection row is increased, and the conducting effect between the pole 71 and the connection row is better. Alternatively, the first plate 2 may also be used to abut against the top cover to be positioned in a matching manner, and when the connection row is installed on one side of the bottom of the battery cell 7, the first plate 2 may form a structure for supporting the battery cell 7, so as to avoid the pole 71 from being inserted too deeply. In addition, when the connection row is mounted on the top side of the battery cell 7, the first plate part 2 also has the function of abutting against the step surface of the top cover or the pole 71 to match and position the pole 71.

Optionally, the connection row further comprises a second plate portion 3 and a U-shaped connection portion 4; the second plate portion 3 is parallel to the first plate portion 2, and the u-shaped connecting portion 4 is used for connecting the first plate portion 2 and the second plate portion 3. Preferably, the top surface of the first plate portion 2 is parallel to the top surface of the second plate portion 3.

The opposite ends of the U-shaped connecting part 4 are respectively connected with the second plate part 3 and the first plate part 2, M first plugging and abutting parts 21 are arranged on the side edge, close to the second plate part 3, of the first plate part 2 at intervals, and M second plugging and abutting parts 31 which are in one-to-one correspondence with the M first plugging and abutting parts 21 are arranged on the side edge, close to the first plate part 2, of the second plate part 3; the first plugging and abutting portions 21 and the corresponding second plugging and abutting portions 31 are separated from each other, and the M first plugging and abutting portions 21 and the M second plugging and abutting portions 31 form a second plugging slot 5 parallel to the first plugging slot 1.

As shown in fig. 5, the first plugging and contacting portion 21 extends from a side edge of the first plate portion 2, the second plugging and contacting portion 31 extends from a side edge of the second plate portion 3, and the first plugging and contacting portion 21 and the second plugging and contacting portion 31 are separated from each other. Therefore, when the pole 71 is inserted into the second inserting groove 5, the first inserting and abutting portion 21 and the second inserting and abutting portion 31 are elastically deformed and are away from each other, so that the pole 71 is easier to be inserted into the second inserting groove 5, and the smooth inserting of the pole 71 is improved.

In particular, the second insertion groove 5 is located between the first plate part 2 and the second plate part 3, so that it is impossible to form the groove wall of the first side as in the first insertion groove 1, regardless of the groove side wall. Therefore, in order to improve the plugging convenience of the second plugging slot 5, the first plate portion 2 and the second plate portion 3 are connected by the U-shaped connection portion 4, so that the first plugging interference portion 21 and the second plugging interference portion 31 have better elastic deformation capability, and the plug of the pole 71 is easier to be realized.

It should be noted that the U-shaped connection 4 needs to be retracted into the pole 71 inserted into the second insertion slot 5.

Alternatively, the first plugging interference portion 21 has a third protruding portion protruding toward the second plugging interference portion 31, and the second plugging interference portion 31 has a fourth protruding portion protruding toward the first plugging interference portion 21. Similarly, the third protruding portion and the fourth protruding portion are provided, so that the first plugging abutting portion 21 and the second plugging abutting portion 31 can better clamp the pole 71, stability of plug connection is improved, and good conduction effect of plug connection is ensured.

Optionally, a third inserting groove 6 is arranged at the edge of one side of the second plate part 3 away from the first inserting groove 1; the third mating groove 6 and the first mating groove 1 are arranged symmetrically with respect to the second mating groove 5. In this embodiment, the pole 71 is in a shape of a Chinese character 'shan', and has three strip-shaped protrusions arranged in parallel with each other at intervals, and the three strip-shaped protrusions are inserted into the first, second and third insertion grooves 1, 5 and 6, respectively. It should be noted that more bar-shaped protrusions may be provided on the pole 71, and more plugging slots are required to be correspondingly provided on the connection rows, so as to meet the requirement of plug connection.
