Description

Technical Field

[0001] This disclosure pertains to the field of new energy equipment, and in particular to a battery pack flip-top mechanism for a new energy heavy truck. Background Technology

[0002] Existing new energy heavy truck battery packs require the integration of multiple key components at the top. The differences in the installation position and height of these components directly result in an uneven surface, which easily leads to snow and dust accumulation and is difficult to clean. This results in low maintenance efficiency, high costs, and may even affect the performance of the battery pack. Summary of the Invention

[0003] In view of the above, it is necessary to provide a battery pack flip-top mechanism for new energy heavy trucks that can automatically cover the battery pack to protect its internal components.

[0004] A battery pack flip-top mechanism used in new energy heavy-duty trucks includes: The left and right flip covers are rotatably connected to the two sides of the top of the battery pack, respectively, to cover the top of the battery pack; The linkage mechanism includes a first link and a second link, one end of the first link is rotatably connected to the left flip cover, and one end of the second link is rotatably connected to the right flip cover; The telescopic rod, with its output end rotatably connected to the other end of the first and second connecting rods, is used to move in the vertical direction and drive the left and right flip covers to rotate via the first and second connecting rods.

[0005] According to the battery pack flip-top mechanism of the new energy heavy truck, the linkage mechanism further includes a third link and a fourth link. One end of the third link is rotatably connected to the first link at the first transition point, and the other end is connected to the fourth link. The other end of the fourth link is rotatably connected to the second link at the second transition point.

[0006] According to the battery pack flip-top mechanism of the new energy heavy truck, the first connecting rod includes a first sub-rod and a second sub-rod rotatably connected to the first sub-rod at the first transition point. The first sub-rod is rotatably connected to the left flip-top, and the second sub-rod is rotatably connected to the output end of the telescopic rod. The second connecting rod includes a third sub-rod and a fourth sub-rod rotatably connected to the third sub-rod at the second transition point. The third sub-rod is rotatably connected to the right flip cover, and the fourth sub-rod is rotatably connected to the output end of the telescopic rod.

[0007] According to the battery pack flip-top mechanism of the new energy heavy truck, the telescopic rod is connected to the battery pack, and the output end moves vertically.

[0008] According to the battery pack flip-top mechanism of the new energy heavy truck, the telescopic rod is an electric push rod.

[0009] According to the battery pack flip-top mechanism of the new energy heavy truck, the first sub-rod is rotatably connected to the outer end of the left flip-top, and the third sub-rod is rotatably connected to the outer end of the right flip-top.

[0010] According to the battery pack flip-top mechanism of the new energy heavy truck, the left flip-top and the right flip-top are rotatably connected to the front and rear sides of the battery pack, and the left and right sides of the battery pack are respectively provided with the linkage mechanism and the telescopic rod.

[0011] Compared to existing technologies, the battery pack flip-top mechanism of the aforementioned new energy heavy truck, when extended or retracted by the telescopic rod, drives the first and second links of the linkage mechanism to move and swing, causing the left and right flip-tops to rotate. This allows the top opening of the battery pack to be closed or opened without affecting its use. Furthermore, it can shield the battery pack from wind, snow, and dust, thus protecting its internal structure and facilitating maintenance. Attached Figure Description

[0019] The following detailed embodiments will further illustrate this disclosure in conjunction with the above-described drawings. Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this disclosure; the described embodiments are merely a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0022] In various embodiments, for ease of description and not limitation of this disclosure, the term "connection" used in the patent application specification and claims is not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0023] like Figure 1-5 As shown, the battery pack flip-top mechanism used in new energy heavy trucks includes a left flip-top 20 and a right flip-top 30, a linkage mechanism 40, and a telescopic rod 50. When the left flip-top 20 and the right flip-top 30 are rotated to the closed state, they close the opening at the top of the battery pack 10, thus protecting it from wind, snow, and dust and safeguarding the internal structure of the battery pack 10. The telescopic rod 50 is used to drive the left flip-top 20 and the right flip-top 30 to rotate through the linkage mechanism 40, thereby achieving the closing and opening actions.

[0024] The left flip cover 20 and the right flip cover 30 are rotatably connected to the two sides of the top of the battery pack 10, respectively, to cover the opening at the top of the battery pack 10. Specifically, the left flip cover 20 and the right flip cover 30 are rotatably connected to the front and rear sides of the battery pack 10, respectively. The left and right sides of the battery pack 10 are respectively provided with the linkage mechanism 40 and the telescopic rod 50. The linkage mechanism 40 and the telescopic rod 50 on the front and rear sides are synchronously arranged to jointly rotate the left flip cover 20 and the right flip cover 30.

[0025] The linkage mechanism 40 includes a first link and a second link. One end of the first link is rotatably connected to the left flip cover 20, and one end of the second link is rotatably connected to the right flip cover 30. When the telescopic rod 50 extends upward, it opens the left flip cover 20 via the first link and the right flip cover 30 via the second link. When the telescopic rod 50 retracts downward, it flips the left flip cover 20 downward and closes via the first link and the right flip cover 30 downward and closes via the second link. Because there is a certain gap (difficult to overlap) between the first and second links and the left and right flip covers 20 and 30, the first and second links may bend and deform. Therefore, the first and second links need to have a certain degree of flexibility.

[0026] Preferably, the first connecting rod includes a first sub-rod 41 and a second sub-rod 42 rotatably connected to the first sub-rod 41 at the first transition point. The first sub-rod 41 is rotatably connected to the left flip cover 20, and the second sub-rod 42 is rotatably connected to the output end of the telescopic rod 50. The second connecting rod includes a third sub-rod 43 and a fourth sub-rod 44 rotatably connected to the third sub-rod 43 at the second transition point. The third sub-rod 43 is rotatably connected to the right flip cover 30, and the fourth sub-rod 44 is rotatably connected to the output end of the telescopic rod 50. The first sub-rod 41 is rotatably connected to the outer end of the left flip cover 20, and the third sub-rod 43 is rotatably connected to the outer end of the right flip cover 30. The linkage mechanism 40 further includes a third connecting rod 45 and a fourth connecting rod 46. One end of the third connecting rod 45 is rotatably connected to the first connecting rod at the first transition point, and the other end is connected to the fourth connecting rod 46. The other end of the fourth connecting rod 46 is rotatably connected to the second connecting rod at the second transition point.

[0027] In this structure, the first and second connecting rods have a certain degree of flexibility, namely, the first sub-rod 41 and the second sub-rod 42 can rotate, and the third sub-rod 43 and the fourth sub-rod 44 can rotate. During operation, the third connecting rod 45 and the fourth connecting rod 46 connect the second sub-rod 42 and the fourth sub-rod 44, forming a triangular structure, which can continue to drive the left flip cover 20 and the right flip cover 30 to the open state through the first sub-rod 41 and the second sub-rod 42; at the same time, during the closing process, the first sub-rod 41 and the second sub-rod 42, and the third sub-rod 43 and the fourth sub-rod 44 can rotate relative to each other to avoid deformation.

[0028] The output end of the telescopic rod 50 is rotatably connected to the other end of the first and second connecting rods, and is used to move vertically, driving the left flip cover 20 and the right flip cover 30 to rotate via the first and second connecting rods. In this embodiment, the telescopic rod 50 is an electric push rod, connected to the front and rear sides of the battery pack 10, and its output end extends and retracts vertically to drive the first and second connecting rods to move.

[0029] During operation, the telescopic rod 50 extends, simultaneously driving the second sub-rod 42 and the fourth sub-rod 44 to move upwards. At the same time, the second sub-rod 42 and the fourth sub-rod 44 rotate and open, while the third connecting rod 45 and the fourth connecting rod 46 pull the second sub-rod 42 and the fourth sub-rod 44. Then, the second sub-rod 42 and the fourth sub-rod 44 drive the left flip cover 20 and the right flip cover 30 to rotate through the first sub-rod 41 and the second sub-rod 42, respectively, thereby opening the top opening of the battery pack 10. When the telescopic rod 50 retracts, it drives the left flip cover 20 and the right flip cover 30 to rotate and close, covering the top opening of the battery pack 10. The entire action process is automatic and requires no manual intervention.

[0030] When the battery pack flip-top mechanism of the aforementioned new energy heavy truck extends or retracts via the telescopic rod 50, it drives the first and second connecting rods of the linkage mechanism 40 to move and swing, thereby causing the left flip-top 20 and the right flip-top 30 to rotate. This allows the top opening of the battery pack 10 to be closed or opened without affecting the use of the battery pack 10. It also protects the internal structure of the battery pack 10 from wind, snow, and dust, and facilitates maintenance, reducing maintenance costs.
