Description

Technical Field

[0001] This utility model relates to the field of battery installation technology, specifically to a battery fixing structure for electric tricycles. Background Technology

[0002] With its outstanding advantages such as convenience, efficiency, environmental friendliness, and good road adaptability, electric tricycles have become an important means of transportation for short-distance urban transportation and community logistics delivery in recent years, thanks to continuous breakthroughs in battery technology.

[0003] As the most crucial performance indicator for electric tricycles, range directly determines the operational efficiency of logistics and delivery, as well as the user experience for end users.

[0004] In the current battery system design of electric tricycles, the battery compartment is fixed under the driver's seat in the lower part of the frame, and the battery is secured by a cover under the seat and limiting components. When removing the battery, the seat needs to be opened and the corresponding mounting screws loosened before the cover and limiting components can be removed, making the process cumbersome during maintenance or battery replacement. It also cannot flexibly install the corresponding number of batteries according to usage needs (reducing the number of battery packs can reduce the vehicle's weight for shorter delivery distances, and for rental batteries, users pay less for renting a single battery). Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a battery fixing structure for electric tricycles. Users can install the corresponding number of batteries according to their needs, and the cover plate, left bracket and right bracket are clamped together by snap-fit, making it easy to install and remove.

[0006] The technical solution adopted in this utility model is as follows: A battery-swapping fixing structure for an electric tricycle includes a base, a left bracket, and a right bracket mounted on a frame. The base has a mounting groove, and at least one partition is provided in the mounting groove. The partition and the inner wall of the mounting groove limit the side wall of the battery. It also includes a cover plate and a latch, the cover plate pressing the top of the battery firmly, and the latch locking the cover plate to the left and right brackets.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The partition can divide the mounting slot into multiple mounting spaces. One partition corresponds to the installation of two batteries, and two partitions correspond to the installation of three batteries. Users can install the corresponding number of batteries according to their needs.

[0008] 2. By using the latch and battery cover together, the cover, left bracket and right bracket are locked together in a snap-fit ​​manner, making it easy to install and remove.

[0009] In a preferred embodiment of this utility model, there are two latches, which are rotatably mounted on both ends of the cover plate. Hooks are provided on both the left and right supports, and a U-shaped groove is provided on the side of the hook away from the cover plate, so that the latch can be locked in the U-shaped groove.

[0010] Beneficial effects: By rotating the latch and the U-shaped groove, the U-shaped groove can limit the vertical and horizontal movement, making it difficult for the latch to come out when the external force is small. It can only come out when the latch is rotated upwards and passes through the U-shaped groove (the hook is made of plastic and can deform to a certain extent), making the device easy to assemble and disassemble.

[0011] In a preferred embodiment of this utility model, one end of the cover plate is hinged to the left or right bracket, and the other end of the cover plate is secured by a latch.

[0012] Beneficial effects: A single latch can also be used, with one end of the cover plate rotatable and the other end connected by a latch. With this installation method, the cover plate remains on the left or right bracket after disassembly and does not need to be removed.

[0013] In a preferred embodiment of this utility model, the latch includes a rotating handle, a U-shaped rod, and a mechanical shaft. The cover plate is equipped with a mounting base. The mechanical shaft is rotatably mounted on the mounting base. Through holes are provided at both ends of the mechanical shaft. The two ends of the U-shaped rod can pass through the through holes and be limited by nuts. The rotating handle can drive the mechanical shaft to rotate, so that the U-shaped rod can be engaged or disengaged from the U-shaped groove of the hook.

[0014] Beneficial effects: The latch uses a U-shaped rod, which utilizes the characteristics of the U-shaped rod to clamp the inner bend into the U-shaped groove. The overall structure is simple and easy to assemble and disassemble.

[0015] In a preferred embodiment of this utility model, the hook includes a horizontal plate and two vertical plates. The horizontal plate is bolted to a left or right bracket. The two vertical plates are integrally formed with the horizontal plate and are located on both sides of the horizontal plate. The U-shaped groove is provided on the side wall of the two vertical plates.

[0016] Beneficial effect: The first support structure described above creates a gap between the two vertical plates, allowing fingers to pass through and making it easier to grip the U-shaped rod and lift it upwards.

[0017] In a preferred embodiment of this utility model, both the left and right brackets are provided with high-voltage cable harness ports and signal cable harness ports.

[0018] Beneficial effects: In order to accommodate multiple battery packs, the vehicle needs to be equipped with a corresponding number of high-voltage wiring harness ports and signal wiring harness ports. For example, when the maximum capacity is two battery packs, the vehicle has two sets of high-voltage wiring harnesses and signal wiring harnesses. When the vehicle is using only one battery, the high-voltage wiring harnesses and signal wiring harnesses that are not inserted into the battery are inserted into the high-voltage wiring harnesses and signal wiring harnesses on the left or right frame to avoid wear caused by vibration, while also providing dustproof and waterproof functions.

[0019] In a preferred embodiment of this utility model, the bottom wall of the cover plate is provided with a shock-absorbing pad.

[0020] Beneficial effects: By using shock-absorbing pads, it has the functions of shock absorption, cushioning and anti-slip. The top is in close contact with the upper surface of the battery, and under the pressure state, it can effectively suppress the displacement and vibration of the battery during driving.
