[0003] The existing soft pack battery pressure test fixture does not have a pressure display function, and there is no rebound space after the clamp is clamped. The fixture does not have a pressure display function, and the user cannot intuitively see the pressure level of the battery pack during the test;

[0004] Moreover, there is no rebound space after the splint is clamped, which will cause the pressure to increase sharply when the battery pack expands during the test, resulting in inaccurate measured data and deformation and damage to the fixture.

[0005] To solve the above problems, this application proposes a soft-pack battery pressurization test fixture with a pressure sensor. Utility Model Content

[0006] To solve the problems raised in the above background technology, the utility model provides a soft pack battery pressure test fixture with a pressure sensor, which allows users to directly observe the pressure during the test and leaves space for the battery pack to expand, so the measured pressure data is more accurate.

A groove A is provided on the surfaces of the second splint and the pressure support plate, a precision guide sleeve is provided in the groove A, the second splint and the pressure support plate are overlapped by the precision guide sleeve, and the end of the precision guide column away from the support platform passes through the second splint, the precision guide sleeve and the pressure support plate, and extends to the top of the pressure support plate, and is connected to the distance screw provided above the pressure support plate;

[0009] A groove B is provided at the center of the second clamping plate, and a pressure sensor is installed in the groove B;

[0010] A spring is wound on the outer side wall of the end face of the precision guide column, and a through hole A is opened on the surface of the pressure support plate. The through hole A is internally threaded with a threaded handle.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figure 1 and Figure 2 As shown;

[0022] A soft pack battery pressure test fixture with a pressure sensor, comprising a support platform, a first clamping plate 1 is fixedly provided on the surface of the support platform, and a precision guide column 9 is symmetrically connected to one side of the support platform surface close to the first clamping plate 1;

[0023] A second plywood 2 is provided above the first plywood 1, and a pressure support plate 4 is provided above the second plywood 2. A groove A is provided on the surface of the second plywood 2 and the pressure support plate 4. A precision guide sleeve 8 is provided in the groove A. The second plywood 2 and the pressure support plate 4 are overlapped by the precision guide sleeve 8, and the end of the precision guide column 9 away from the support platform passes through the second plywood 2, the precision guide sleeve 8 and the pressure support plate 4, and extends to the top of the pressure support plate 4, and is connected to the distance screw 6 provided above the pressure support plate 4;

[0024] A groove B is formed at the center of the second clamping plate 2, and a pressure sensor 3 is installed in the groove B;

[0025] A spring 5 is wound on the outer wall of the end surface of the precision guide pillar 9 , and a through hole A is opened on the surface of the pressure support plate 4 , and a threaded handle 7 is connected to the inner thread of the through hole A.

[0026] In this embodiment: the battery pack is placed between the first plywood 1 and the second plywood 2. Since the end of the precision guide column 9 away from the support platform passes through the second plywood 2, the precision guide sleeve 8 and the pressure support plate 4 (that is, the second plywood 2, the precision guide sleeve 8 and the pressure support plate 4 will slide on the precision guide column 9), the components above the second plywood 2 will squeeze the battery pack. The staff rotates the threaded handle 7, so that the threaded handle 7 and the pressure sensor 3 conflict with each other. The user can directly observe the pressure during the test. A spring 5 is wound on the outer wall of the end face of the precision guide column 9. One end of the spring 5 is fixedly connected to the top of the distance screw 6, and the other end of the spring 5 is fixedly connected to the surface of the pressure support plate 4. The design of this spring 5 can leave space for the battery pack to expand, thereby making the measured pressure data more accurate.

[0027] In an optional embodiment, four feet 10 are fixedly provided on the bottom surface of the support platform, and the four feet 10 are symmetrically distributed on the bottom surface of the support platform.

[0028] In this embodiment, since the four feet 10 are symmetrically distributed on the bottom surface of the support platform, the support platform can be made more stable during operation.

[0029] In an optional embodiment, one end of the spring 5 is fixedly connected to the top end of the distance screw 6 , and the other end of the spring 5 is fixedly connected to the surface of the pressure support plate 4 .

[0030] In this embodiment: because one end of the spring 5 is fixedly connected to the top of the distance screw 6, and the other end of the spring 5 is fixedly connected to the surface of the pressure support plate 4, the design of this spring 5 can leave space for the battery pack to expand, thereby making the measured pressure data more accurate.

[0031] In an optional embodiment, one end of the threaded handle 7 close to the second clamping plate 2 extends to below the pressure support plate 4 and is directly above the pressure sensor 3 .

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
