Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery technology, specifically to an electric vehicle battery mounting structure. Background Technology

[0002] As the power source for the normal use of electric vehicles, the reliability and stability of the battery installation on electric vehicles are of paramount importance.

[0003] According to a public notice regarding an electric vehicle battery installation structure (Announcement No.: CN218569085U), the two sets of brackets in the aforementioned application have circular through holes and elongated holes respectively, which are connected and locked to the lower frame. The circular through holes serve as the main positioning, and the elongated holes serve as the auxiliary positioning. In addition, it can also adapt to the battery length when installing the first battery in the event of inaccurate mounting holes due to manufacturing errors. Of course, the distance between the two brackets can also be adjusted appropriately according to actual needs.

[0004] However, in actual use, the above-mentioned equipment requires a gap between the side wall of the battery and the rack when the battery is placed inside the rack to facilitate battery installation. Especially when there are many batteries, the pressure strip is too long and is prone to bending and leaving gaps during use, affecting the installation of surrounding parts and its own stability. In view of this, we propose an electric vehicle battery installation structure. Summary of the Invention

[0005] The purpose of this invention is to provide an electric vehicle battery mounting structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric vehicle battery mounting structure, including a mounting frame, a battery disposed on the upper surface of the mounting frame, a fixing mechanism disposed above the mounting frame, and an auxiliary mechanism disposed above the mounting frame. The fixing mechanism includes: A fixed base is detachably connected to the upper surface of the placement frame by bolts. A connecting rod is fixedly installed on the upper surface of the fixed base. A pressure strip is provided on the arc surface of the connecting rod. A limit plate is fixedly installed on the side wall of the pressure strip. A nut is threaded onto the arc surface of the connecting rod, a threaded rod is threaded onto the inner wall of the limiting plate, and a rubber protrusion is fixedly installed on the side wall of the limiting plate.

[0007] Preferably, there are two fixing seats, which are arranged in a mirror image on the upper surface of the placement rack.

[0008] Preferably, the limiting plate is L-shaped, and the end sidewall of the limiting plate can fit against the sidewall of the battery, with the two limiting plates limiting the two sidewalls of the battery.

[0009] Preferably, the lower surface of the pressure strip is attached to the upper surface of the battery, and the pressure strip, together with the limiting plate, can fit the battery inside, thereby stably limiting the outer surface of the battery.

[0010] Preferably, the connecting rod passes through the pressure bar, and the upper arc surface of the connecting rod is provided with an external thread, thereby adjusting the nut so that the pressure bar is limited by the connecting rod, thus limiting the upper end of the battery.

[0011] Preferably, the auxiliary mechanism includes a positioning groove, which is formed on the lower surface of the pressure strip, and a rubber strip is fixedly installed on the inner wall of the positioning groove.

[0012] Preferably, the positioning groove is an inclined circular groove, and the positioning groove is fitted onto the arc surface of the battery connecting wire, so that the battery connecting wire is limited by the positioning groove on the pressure strip, reducing the impact of the pressure strip on battery fixation.

[0013] Compared with the prior art, the present invention provides an electric vehicle battery mounting structure, which has the following advantages: 1. This electric vehicle battery mounting structure features a fixing mechanism where multiple batteries are sequentially mounted on a mounting bracket. Tightening the adjusting nut causes the pressure strip to move downwards under the guidance and limitation of the connecting rod, thus limiting the top of the battery. Simultaneously, rubber protrusions on the side limit plates provide elastic constraints on the battery sidewalls. Combined with the precise positioning of the adjustable threaded rod, this achieves stable multi-angle fixing of the battery. This structure, through the limiting action of the connecting rod and the limit plates, significantly improves the stability of the pressure strip itself.

[0014] 2. The battery installation structure of this electric vehicle is equipped with an auxiliary mechanism. The pressure strip has a positioning groove and a rubber strip to orderly limit the battery connection wires, effectively avoiding the problem of loosening caused by wire harness interference. This ensures that the pressure strip can always apply force evenly to the battery surface, significantly improving the overall stability and reliability of the fixation. Attached Figure Description

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: an electric vehicle battery installation structure, including a placement rack 1, a battery 2 disposed on the upper surface of the placement rack 1, a fixing mechanism 3 disposed above the placement rack 1, and an auxiliary mechanism 4 disposed above the placement rack 1. The fixing mechanism 3 includes a fixing seat 301, a connecting rod 302, a pressure strip 303, a nut 304, a limiting plate 305, a threaded rod 306, and a rubber protrusion 307.

[0018] In one embodiment of this utility model, the fixing base 301 is detachably connected to the upper surface of the placement frame 1 by bolts. A connecting rod 302 is fixedly installed on the upper surface of the fixing base 301. A pressure strip 303 is provided on the arc surface of the connecting rod 302. A limiting plate 305 is fixedly installed on the side wall of the pressure strip 303. A nut 304 is threadedly installed on the arc surface of the connecting rod 302. A threaded rod 306 is threadedly connected to the inner wall of the limiting plate 305. A rubber protrusion 307 is fixedly installed on the side wall of the limiting plate 305.

[0019] In addition, there are two fixing seats 301, which are arranged in a mirror image on the upper surface of the placement rack 1. The limiting plate 305 is L-shaped, and the end side wall of the limiting plate 305 can fit against the side wall of the battery 2. The two limiting plates 305 limit the two side walls of the battery 2.

[0020] In this embodiment of the invention, the lower surface of the pressure strip 303 is attached to the upper surface of the battery 2. The pressure strip 303, together with the limiting plate 305, can fit the battery 2 inside, thereby stably limiting the outer surface of the battery 2. The connecting rod 302 passes through the pressure strip 303, and the upper arc surface of the connecting rod 302 is provided with an external thread. The adjusting nut 304 allows the pressure strip 303 to be limited by the connecting rod 302, thereby limiting the upper end of the battery 2. The auxiliary mechanism 4 includes a positioning groove 401, which is formed on the lower surface of the pressure strip 303. A rubber strip 402 is fixedly installed on the inner wall of the positioning groove 401. The positioning groove 401 is in the shape of an inclined circular groove, and the positioning groove 401 is fitted on the arc surface of the battery 2 connecting line, so that the connecting line of the battery 2 is limited by the positioning groove 401 on the pressure strip 303, reducing the influence of the pressure strip 303 on the fixing of the battery 2. The male and female structures are respectively set at both ends of the battery 2. When the batteries 2 are arranged, the batteries 2 are forced to be staggered, so that the ends of adjacent batteries 2 have different polarities, and the connecting lines can be configured to connect them.

[0021] In this invention, multiple batteries 2 are sequentially mounted on the mounting bracket 1. By tightening the adjusting nut 304, the pressure strip 303 moves downward under the guidance and limitation of the connecting rod 302, thus limiting the top of the battery 2. Simultaneously, the rubber protrusions 307 on the side limiting plates 305 provide elastic constraints on the sidewalls of the battery 2. Combined with the precise positioning of the adjustable threaded rod 306, this achieves stable fixation of the battery 2 at multiple angles. This structure, through the limiting effect of the connecting rod 302 and the limiting plates 305, significantly improves the stability of the pressure strip 303 itself.

[0022] Furthermore, the pressure strip 303 is provided with a positioning groove 401 and a rubber strip 402 to orderly limit the connection wire of the battery 2, effectively avoiding the problem of loosening caused by wire harness interference, so that the pressure strip 303 can always apply force evenly to the surface of the battery 2, significantly improving the overall stability and reliability of the fixation.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
