Description

Technical Field

[0001] This utility model relates to the field of electric-assisted bicycle technology, and in particular to a battery bracket, battery module, and electric-assisted bicycle for electric-assisted bicycles. Background Technology

[0002] In the electric bicycle industry, the battery is one of the core components, and its ease of installation and removal, as well as its spatial adaptability, have a significant impact on user experience. Currently, the existing battery installation structure for electric bicycles has obvious shortcomings: the existing battery box installation and removal process is limited to the plane formed by the bicycle frame, and space must be reserved for the battery box installation and removal. This is largely limited by the height of the frame, which restricts the size of the battery box, thereby limiting the battery capacity, resulting in a short driving range and affecting the user's convenience. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem of limited capacity caused by the battery being restricted by the disassembly method in the prior art, this utility model provides a battery bracket, battery module and electric assist bicycle for electric assist bicycles that can be disassembled from the battery box in a direction perpendicular to the plane of the bicycle frame.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a battery bracket for an electric-assisted bicycle, including a bracket base, wherein one, two or more sets of mounting buckles are arranged at intervals on both sides of the bracket base along its length direction, each set of mounting buckles includes two or more mounting buckles arranged opposite each other, the bracket base is used to connect with the bicycle frame, and the latches of the mounting buckles are substantially perpendicular to the plane formed by the bicycle frame.

[0005] The number of mounting clips should be at least one set; setting two or more sets of mounting clips helps to ensure the stability of the battery box when mounted on the bracket base.

[0006] The mounting clips that are arranged opposite each other are not required to be positioned exactly on both sides of the length of the bracket base. It is permissible for a set of mounting clips to be staggered by a certain position in the length of the bracket base. The number of mounting clips in a set can be two or more. For example, one mounting clip is provided on one side of the bracket base and two mounting clips are provided on the other side.

[0007] Furthermore, the mounting clip and the bracket base are detachably connected; the purpose of the detachable connection is to remove and install the battery; the battery can be easily installed or removed simply by removing the mounting clip on one side from the bracket base.

[0008] Furthermore, the mounting clips are connected to the bracket base by screws. One side of the mounting clips is first installed on the bracket base by screws, and the other side of the mounting clips is connected to the battery box. The battery box enters the plane of the bicycle frame along the vertical direction formed by the bicycle frame. After engaging with the mounting clips on the other side that are already fixed to the bracket base, the mounting clips on the side connected to the battery box are then fixedly connected to the bracket base by screws.

[0009] Furthermore, the bottom of the mounting buckle is positioned above or below the bracket base. When positioned below the bracket base, the sides and bottom of the mounting buckle are connected to the bracket base by screws. When positioned above the bracket base, the bottom of the mounting buckle is connected to the bracket base by screws.

[0010] Furthermore, when the bottom of the mounting buckle is positioned above the bracket base, a protrusion can be provided in the middle of the bracket base to increase the stability of the connection between the battery box and the battery bracket; and by raising the battery box, the height of its side slot can be matched with the height of the mounting buckle tongue.

[0011] Furthermore, the mounting buckle is adapted to the side slot of the battery box, and the end of the buckle tongue is provided with a guide slope to facilitate its connection with the battery box slot.

[0012] Furthermore, the bracket base is provided with connecting holes, two connecting holes are arranged in a group, and are spaced apart on the bracket base. The connecting holes are used for clamps to pass through and connect and fix the bracket base to the bicycle frame.

[0013] Furthermore, the bracket base is provided with a connection hole, which is used to connect and fix the bracket to the water bottle hole on the bicycle frame by screws.

[0014] Furthermore, the bracket base is provided with reinforcing ribs along its length, which increases the contact area between the bracket base and the vehicle frame and plays a role in preventing slippage.

[0015] Furthermore, the support base is made of aluminum alloy.

[0016] This utility model also provides a battery module for an electric-assisted bicycle, including a bracket base and a battery box; the bracket base is provided with a mounting buckle on at least one side, and the battery box is provided with a side slot that matches the mounting buckle at a corresponding position, and is connected to the bracket base through the mounting buckle; the bracket base is used to connect to the bicycle frame, and the latch of the mounting buckle is substantially perpendicular to the plane formed by the bicycle frame.

[0017] The bracket base can have mounting clips on both sides, and the battery box can be connected to it through the mounting clips; the bracket base can also have a mounting clip on one side, and one side of the battery box can be connected to the bracket base through the mounting clip, while the other side can be detachably connected to the bracket base, such as by screws, pins or other common detachable connection methods.

[0018] This utility model also provides an electric-assisted bicycle with a battery bracket, including a frame and the aforementioned electric-assisted bicycle battery module mounted on the frame; the mounting on the frame is not limited to the top of the frame, but can be any suitable mounting position within the frame space.

[0019] The beneficial effects of this utility model are:

[0020] (1) The battery bracket for electric bicycles described in this utility model has strong spatial adaptability; it breaks through the problem that the battery can be removed and placed in the plane formed by the traditional bicycle frame due to the height of the frame, and realizes disassembly and installation in a direction perpendicular to the plane of the frame. Even in scenarios where the frame height is low and the battery box is large, it can still be operated smoothly, thus expanding the flexibility of the battery installation layout of electric bicycles.

[0021] (2) The electric-assisted bicycle with battery bracket described in this utility model can increase the capacity of the battery box after the battery is installed using such bracket, thereby extending the range and time and improving the user experience. Attached Figure Description
