Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features.

[0026] Please refer to Figures 1-5The utility model provides a battery pack assembly structure, including installation box 100 and pressure frame 104, the four corners of pressure frame 104 bottom are all conical structure, the side surface of installation box 100 is provided with T -shaped slot 101, and the other side surface of installation box 100 is provided with the T -shaped plate 102 matched with T -shaped slot 101.

[0027] In use, first two T -shaped plates 102 on installation box 100 are slid into T -shaped slot 101 and are preliminarily assembled, at this time, the insertion hole B 106 is aligned with the mounting hole 107, then two lithium batteries are inserted into two installation boxes 100 respectively, then four corners of pressure frame 104 are inserted into four insertion grooves 103 respectively, and are fixed using fixing mechanism 200, so that pressure frame 104 can be tightly pressed on the surface of lithium battery and fixed, and through the extrusion cooperation of top rod 108 and pressure frame 104, when pressure frame 104 is inserted into insertion groove 103, top rod 108 is pushed out from mounting hole 107 and inserted into insertion hole B 106, since T -shaped plate 102 and T -shaped slot 101 can provide horizontal direction limiting, and top rod 108 and insertion hole B 106 can provide vertical direction limiting, so the purpose of fixing and assembling two lithium batteries is realized simultaneously.

[0028] When pressure frame 104 is extracted from insertion groove 103, elastic mechanism 300 can drive top rod 108 to be automatically extracted from insertion hole B 106, and the purpose of separation is realized.

[0029] It is worth mentioning that the application is exemplified by two installation boxes 100, and in actual use, a proper number of installation boxes 100 can be selected for assembly according to requirements.

[0030] Preferably, fixing mechanism 200 includes fixing pipe 201 installed on the upper surface of installation box 100, plug rod 202 is slidingly installed on both sides in the inside of fixing pipe 201, spring A 203 is arranged in the inside of fixing pipe 201, and both ends of spring A 203 are respectively abutted with two plug rods 202.

[0031] When the four corners of the pressing frame 104 are inserted into the insertion slot 103, the tapered structure at the bottom of the pressing frame 104 will squeeze the end of the insertion rod 202, and the insertion rod 202 will be squeezed to move to the middle position of the fixing tube 201 and compress the spring A 203. As the pressing frame 104 continues to penetrate, when the insertion hole A 105 is aligned with the insertion rod 202, the compressed spring A 203 releases the elastic force, thereby pushing the insertion rod 202 to automatically insert into the insertion hole A 105 to complete the fixation.

[0032] Preferably, the elastic mechanism 300 includes a shaft shoulder 301 arranged on the outer surface of the top rod 108, the shaft shoulder 301 is arranged in the inner part of the mounting hole 107, the outer surface of the top rod 108 is sleeved with a spring B 302, and the two ends of the spring B 302 are respectively in abutment with the shaft shoulder 301 and the inner wall of the mounting hole 107.

[0033] Normally, the top rod 108 is inserted into the pressing frame 104 at one end and is in the inner part of the mounting hole 107 at the other end. When the top rod 108 is squeezed by the tapered structure at the bottom of the pressing frame 104, it can be retracted into the inner part of the mounting hole 107, and the shaft shoulder 301 can compress the spring B 302, so that the other end of the spring B 302 is inserted into the insertion hole B 106. Since the pressing frame 104 is fixed by the fixing mechanism 200, the top rod 108 can be continuously inserted into the insertion hole B 106 to achieve the purpose of assembly. When the pressing frame 104 is pulled out of the insertion slot 103, the compressed spring B 302 releases the elastic force to push the top rod 108 out of the insertion hole B 106.

[0034] Preferably, the inner part of the insertion slot 103 is provided with a spring C 400.

[0035] When the pressing frame 104 is inserted into the insertion slot 103, the spring C 400 is compressed. When the fixing mechanism 200 is removed from the pressing frame 104, the compressed spring C 400 releases the elastic force to push the pressing frame 104 upwards, so that the pressing frame 104 leaves a gap with the upper surface of the lithium battery, and the insertion hole A 105 is misaligned with the insertion rod 202, which facilitates manual pulling of the pressing frame 104 out of the insertion slot 103.

[0036] Preferably, the inner part of the insertion slot 103 is provided with a spring C 400.

[0037] Through the arrangement of the telescopic rod 500 and the top plate 501, the spring C 400 can stably apply a pushing force under the demand of the elastic force.

[0038] Preferably, the outer surface of the fixing tube 201 is provided with two sliding grooves 600, the inner part of the sliding groove 600 is provided with a push rod 601, and the end of the push rod 601 is connected with the insertion rod 202.

[0039] By turning the dial lever 601, the insertion rod 202 can be slid to facilitate the extraction of the insertion rod 202 from the insertion hole A105, thereby releasing the fixation of the pressing frame 104.

[0040] Preferably, the lower surface of the pressing frame 104 is provided with a rubber pad.

[0041] The rubber pad has good shock absorption performance. When the lithium battery is subjected to external impact or vibration, the rubber pad can absorb and disperse the impact force, thereby protecting the lithium battery from damage, helping to prolong the service life of the lithium battery, and ensuring its stability and reliability.

[0042] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
