[0033] It should be noted that in different drawings, the same reference numerals denote the same or substantially the same components.
[0034] like Figure 1 As shown, a battery limiting structure of a preferred embodiment of the utility model is provided, and the battery limiting structure has a first direction X and a second direction Y.
[0035] See also Figure 1 , Figure 3 as well as Figure 7The battery limiting structure includes: a shell 1, a cover 2, a plurality of first support ribs 3, a plurality of first limiting ribs 4, and a bracket 5 for installing a battery 18. The shell 1 has an installation cavity 101 and an opening 102, and the opening 102 is connected to the installation cavity 101. During installation, the staff can install the bracket 5 into the installation cavity 101 from the opening 102. A plurality of first support ribs 3 are arranged on the side wall of the installation cavity 101 at intervals along the first direction X, and a first card slot 31 is provided on the first support rib 3. The first card slot 31 is located in the installation cavity 101, and the first card slot 31 is arranged on the side of the first support rib 3 facing away from the shell. A plurality of first limiting ribs 4 are arranged on the bracket 5 at intervals along the second direction Y, and the first limiting rib 4 is clamped in the first card slot 31 between two adjacent first support ribs 3. The cover 2 is covered on the opening 102.
[0036] It should be noted that according to Figure 1 and 2 As shown, in the embodiment of the utility model, the first direction intersects with the second direction. In this embodiment, the first direction and the second direction are coplanar and perpendicular to each other. It is further explained that the definition of vertical in the specification should be understood as vertical within a 10% fluctuation of 90 degrees, that is, the angle between the defined first direction and the second direction should be understood as vertical when it is between 80 degrees and 90 degrees. For ease of understanding, the following will be explained with the first direction X as the length direction of the battery limiting structure and the second direction Y as the width direction of the battery limiting structure.
[0037] Based on the above structure, the present application sets a first supporting rib 3 on the side wall of the installation cavity 101 to separate the side wall of the installation cavity 101 from the bracket 5, thereby avoiding the bracket 5 from vibrating in the face shell and rubbing against the face shell during transportation, thereby generating abnormal noise. At the same time, a first card slot 31 is opened on the first supporting rib 3, and the bracket 5 is clamped in the first card slot 31 by the first limiting rib 4 on the bracket 5 to achieve the limited fixation between the bracket 5 and the shell 1. Compared with the previous method of setting an attached foam between the bracket 5 and the face shell, the present application uses the first limiting rib 4 instead of the attached foam, thereby achieving the effect of reducing material costs. At the same time, it can also increase the space between the bracket 5 and the face shell, thereby improving the heat dissipation effect of the battery 18 in the bracket 5.
[0038] Further, see Figure 4 , Figure 6 as well as Figure 8 A first ridge 6 is provided on the edge of the cover body 2, and a groove 103 is provided on the edge of the opening 102. The first ridge 6 is inserted into the groove 103 to achieve the limited fixation between the face shell and the cover body 2. When the cover body 2 and the face shell are connected, the present application first applies glue in the groove 103, and then inserts the first ridge 6 on the face shell into the groove 103 to achieve the connection and fixation between the cover body 2 and the face shell.
[0039] Specifically, the first ridge 6 is provided in an annular manner along the edge of the cover body 2 , and the groove 103 is provided in an annular manner along the edge of the opening 102 , so that the cover body 2 and the face shell are limited in both the first direction X and the second direction Y.
[0040] In one possible embodiment, see Figure 4 and Figure 6 , the present application further includes: a second ridge 7, a third ridge 8 and a fourth ridge 9. The second ridge 7 and the third ridge 8 are arranged on the inner wall of the cover body 2, and a second groove 10 extending along the first direction X is provided between the second ridge 7 and the third ridge 8. The fourth ridge 9 is arranged on the bracket 5 along the first direction X, the fourth ridge 9 is clamped in the second groove 10, and the two sides of the fourth ridge 9 in the second direction Y are respectively abutted against the second ridge 7 and the third ridge 8, so that the cover body 2 is not only limited by the first ridge 6 and the groove 103 in the second direction Y, but also limited by the second ridge 7, the third ridge 8 and the fourth ridge 9, so as to further improve the connection stability between the face shell and the cover body 2 in the second direction Y.
[0041] In order to further improve the connection stability between the face shell and the cover body 2 in the second direction Y, the present application can also set multiple groups of second ridges 7 and third ridges 8 on the inner wall of the cover body 2, and set a corresponding number of fourth ridges 9 on the bracket 5, and achieve the connection stability between the cover body 2 and the face shell in the second direction Y by clamping the fourth ridge 9 between the second ridge 7 and the third ridge 8.
[0042] In one possible embodiment, see Figure 2 , the present application also includes: a plurality of limiting portions 11. The plurality of limiting portions 11 are arranged on the bracket 5 at intervals along the first direction X, and a limiting groove 111 is formed between two adjacent limiting portions 11, so that the plurality of limiting grooves 111 are arranged at intervals along the first direction X. The number of the second ridges 7 in the second direction Y is multiple, at least one of the plurality of second ridges 7 is clamped in the limiting groove 111, and the second ridge 7 is in contact with the limiting portion 11, so that the second ridge 7 is limited by the limiting portion 11 in the first direction X, so that the cover body 2 is not only limited by the first ridge 6 and the groove 103 in the first direction X, but also limited by the second ridge 7 and the limiting portion 11, further improving the connection stability between the face shell and the cover body 2 in the first direction X.
[0043] Further, see Figure 7 and Figure 8, the present application also includes: a plurality of second limiting ribs 12. A plurality of third card slots 51 are arranged at intervals along the second direction Y on the side of the bracket 5 facing away from the opening 102, the third card slots 51 penetrate the bracket 5 along the first direction X, a plurality of second limiting ribs 12 are arranged at intervals along the second direction Y on the first support rib 3, the second limiting rib 12 is clamped in the third card slot 51, and the arrangement between the second limiting rib 12 and the third card slot 51 can improve the connection stability between the face shell and the cover body 2 in the second direction Y.
[0044] Furthermore, the side of the first support rib 3 facing away from the side wall of the installation cavity 101 is fitted with the bracket 5, so that the first support rib 3 can fill the gap between the bracket 5 and the side wall of the installation cavity 101. Compared with the previous method of setting an attached foam between the bracket 5 and the surface shell, the present application uses the first limiting rib 4 instead of the attached foam, thereby achieving the effect of reducing material costs. At the same time, it can also increase the space between the bracket 5 and the surface shell, thereby improving the heat dissipation effect of the battery 18 in the bracket 5.
[0045] In one possible embodiment, see Figure 1 , the present application further includes: a fastening bolt 13. A first connecting hole is provided on the cover body 2, and a threaded hole is provided on the shell body 1. The fastening bolt 13 is passed through the first connecting hole and is threadedly connected with the threaded hole, so that the cover body 2 is fixed to the shell body 1. The screw rod of the fastening bolt 13 is passed through the connecting hole and is threadedly connected with the threaded hole. The nut of the fastening bolt 13 abuts against the side of the cover body 2 away from the surface shell, so that the cover body 2 and the shell body 1 are fixedly connected.
[0046] In one possible embodiment, see Figure 8 The present application further includes: a second support rib 14. The second support rib 14 is disposed on both side surfaces of the mounting cavity 101 in the first direction X, and the second support rib 14 abuts against the bracket 5, so that the bracket 5 is limited not only by the second convex strip 7 and the limiting portion 11 in the first direction X, but also by the second support rib 14, further improving the stability of the bracket 5 in the second direction Y in the mounting cavity 101.
[0047] It is understandable that the number of the second support ribs 14 can be one or more. When the number of the second support ribs 14 is multiple, the multiple second support ribs 14 are arranged at intervals along the second direction Y on both side surfaces of the installation cavity 101 in the first direction X.
[0048] The following describes the battery pack of the second embodiment of the present invention. Figure 1 , including a first bus bar 15, a second bus bar 16, a PCM board 17, a plurality of batteries 18 and a battery limiting structure as described in the above embodiment.
[0049] The bracket 5 has multiple installation channels extending along the first direction X, and multiple batteries 18 are installed in the multiple installation channels one by one. The battery 18 has a first connecting portion and a second connecting portion. The first bus 15 connects the first connecting portions of the multiple batteries 18, and the second bus 16 connects the second connecting portions of the multiple batteries 18. The PCM board 17 is electrically connected to the first bus 15 and the second bus 16 respectively.
[0050] Further, see Figure 1 The PCM board 17 is arranged between the bracket 5 and the cover body 2, and the PCM board 17 is clamped on the limiting part 11 arranged at intervals along the second direction Y on the inner wall of the cover body 2, so that the limiting part 11 of the application not only forms a limit for the cover body 2 in the first direction X with the second convex strip 7, but also plays a role in limiting and fixing the PCM board 17.
[0051] When the present application needs to be assembled, firstly, multiple batteries are installed one by one into the bracket, and the first bus and the second bus are respectively arranged at the two ends of the battery, so that the first bus and the second bus are respectively connected to the ends of multiple batteries, and then the bracket 5 is installed from the opening 102 into the first support rib 3 of the installation cavity 101 to separate the side wall of the installation cavity 101 from the bracket 5. At this time, the bracket 5 is clamped in the first card groove 31 through the first limiting rib 4 to achieve the limiting fixation between the bracket 5 and the housing 1. Secondly, in the first direction, the second supporting rib 14 abuts against the bracket 5, so that the bracket 5 is not only limited by the second convex strip 7 and the limiting portion 11 in the first direction X. After the bracket 5 is installed, the cover body 2 is placed on the opening 102, and the first ridge 6 is clamped in the groove 103 to achieve the limit fixation between the face shell and the cover body 2. At the same time, the fourth ridge 9 is clamped in the second clamping groove 10, and the fourth ridge 9 is respectively abutted against the second ridge 7 and the third ridge 8 on both sides in the second direction Y, so that the cover body 2 is not only limited by the first ridge 6 and the groove 103 in the second direction Y, but also limited by the second ridge 7, the third ridge 8 and the fourth ridge 9. Secondly, the second ridge 7 abuts against the limiting portion 11, so that the cover body is also limited by the second ridge 7 and the limiting portion 11, further improving the connection stability between the face shell and the cover body 2 in the first direction X.
[0052] In summary, the embodiment of the utility model provides a battery limiting structure and a battery pack, which arranges a first supporting rib 3 on the side wall of the installation cavity 101 to separate the side wall of the installation cavity 101 from the bracket 5, thereby avoiding the bracket 5 from vibrating in the face shell and rubbing against the face shell during transportation, thereby generating abnormal noise. At the same time, a first card slot 31 is opened on the first supporting rib 3, and the bracket 5 is clamped in the first card slot 31 by the first limiting rib 4 on the bracket 5 to achieve limiting fixation between the bracket 5 and the shell 1. Compared with the previous method of requiring an attached foam to be arranged between the bracket 5 and the face shell, the present application utilizes the first limiting rib 4 instead of the attached foam, thereby achieving the effect of reducing material costs. At the same time, it can also increase the space between the bracket 5 and the face shell, thereby improving the heat dissipation effect of the battery 18 in the bracket 5.
[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
