Description

Technical Field

[0001] This utility model relates to the field of battery brackets, and in particular to an electric vehicle battery bracket. Background Technology

[0002] Electric bicycles, as a convenient, lightweight, and environmentally friendly personal transportation tool, are based on ordinary bicycles with the addition of components such as motors, controllers, and batteries, giving them a certain level of power performance. Due to their convenience, they are favored by a wide range of consumers. The batteries used in electric bicycles are mostly lead-acid batteries, with some being lithium batteries. The batteries are generally located under the seat or footrests, usually mounted on an independent battery rack, forming a separate battery compartment structure. However, when riding an electric bicycle, the battery can overheat, especially in hot weather, such as summer. The heat cannot dissipate quickly enough, causing it to accumulate inside the battery compartment, resulting in a relatively high battery temperature. This increases the battery's internal resistance and may even cause the battery to swell, affecting its performance. Utility Model Content

[0003] The main purpose of this utility model is to provide an electric vehicle battery bracket that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An electric vehicle battery bracket, comprising:

[0006] main body;

[0007] A cover plate that fits over the top of the main body;

[0008] Two inner panels are slidably installed in the inner cavity of the main body and are set perpendicular to the bottom of the main body. A battery compartment is formed between the two inner panels for placing batteries, and an air duct is formed between the inner panels and the side wall of the main body.

[0009] Ventilation vents are located on the side walls of the main body to allow for ventilation inside the main body.

[0010] A waist-shaped groove is cut through the cover plate to fix the position of the inner plate.

[0011] Furthermore, a groove is provided on the inner side wall of the main body perpendicular to the inner plate, and sliders matching the groove are provided at both ends of the inner plate.

[0012] Furthermore, a raised strip protruding outward is fixedly installed on the rear side wall of the air vent located at the front of the main body.

[0013] Furthermore, a partition is fixedly installed on the inner bottom of the main body, which separates the two inner panels into independent battery compartments. The two ends of the partition penetrate the inner panels and are located in the air duct.

[0014] Furthermore, the partition is a double-layered structure, with ventilation slots formed between the two layers.

[0015] Furthermore, a through hole is provided at the bottom of the air duct.

[0016] Furthermore, the inner panel can slide on the partition.

[0017] Furthermore, the convex strip is set to tilt forward.

[0018] Furthermore, the top of the inner panel has threaded holes, and bolts are installed in the waist-shaped groove for fixing the inner panel.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model features a main body with ventilation holes and two inner plates that slide inside the main body. These inner plates form a ventilation channel between the main body and the side wall of the main body. The ventilation holes allow air to flow into the ventilation channel. When riding, the flowing air enters the ventilation channel of the main body, which helps to dissipate heat from the battery.

[0021] Because the inner panel can slide inside the main body, the distance between the two inner panels can be adjusted to accommodate batteries of different sizes. When replacing the battery, the distance between the two inner panels can be increased to make it easier to remove and replace the battery. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0038] Please see 1- Figure 14 As shown, this embodiment provides an electric vehicle battery bracket, including a main body 1. The main body 1 is a box structure with an opening at the top. A cover plate 2 is installed at the opening of the main body 1 by bolts, and the cover plate 2 covers the opening of the main body 1.

[0039] Two inner panels 7 are placed perpendicular to the bottom of the main body 1. The inner panels 7 slide inside the main body 1 and can slide horizontally within the main body 1. A battery compartment is formed between the two inner panels 7 for housing the electric vehicle's battery. Figure 2 , Figure 4 , Figure 5 As shown, the inner panel 7 is parallel to two of the side walls of the main body 1 and perpendicular to the other two side walls. An air duct 8 is formed between the inner panel 7 and the two side walls of the main body 1 that are parallel to it.

[0040] like Figure 2 and Figure 3As shown, a groove 72 is provided on the side wall of the main body 1 perpendicular to the inner plate 7. Slider 71 that cooperates with the groove 72 is provided at both ends of the inner plate 7. The slider 71 is located in the groove 72 and can slide horizontally in the groove 72.

[0041] The cover plate 2 has a slotted groove 3, in which a bolt is installed. The top of the inner plate 7 has a threaded hole; the bolt is screwed into the threaded hole to fix the inner plate 7, thus securing the inner plate 7 to the cover plate 2. Figure 10 As shown. For batteries of different lengths, the inner plate 7 can be adjusted in position inside the main body 1 to accommodate batteries of different sizes.

[0042] When placing the battery, the inner plate 7 can be slid outwards to increase the distance between the two inner plates 7, thus increasing the space for placing the battery and making it easier to place the battery in the battery compartment. Keep the battery aligned as much as possible. After the battery is placed, slide the two inner plates to ensure they are in contact with the side wall of the battery. Then, cover the inner plate 2 to secure it. Note that before securing the inner plate 7, the cover 2 needs to be bolted to the main body 1. Then, insert your fingers, screwdriver, wrench, or other long-handled tools into the waist-shaped groove 3 and press them against the side wall of the inner plate 7. This allows you to move the inner plate 7 against the outer wall of the battery. Once the inner plate 7 is in contact with the outer wall of the battery, it can be fixed in the waist-shaped groove, thus securing the battery.

[0043] Ventilation holes 4 are evenly distributed on the side wall of the main body 1, enabling ventilation of the air duct 8. Especially when the electric vehicle is in motion, air enters the air duct 8 through the ventilation holes, dissipating heat from the battery placed inside the main body 1. In this embodiment, a protruding rib 5 is fixedly installed on the rear side wall of the ventilation holes 4 located on the front side of the main body 1. Figure 1 , Figure 2 , Figures 4-8 and Figures 12-14 As shown, the outer end of the protrusion 5 is inclined forward. When the electric vehicle moves forward, the protrusion 5 can guide the air from the air hole 4 into the air duct 8. When the air flows inside the air duct 8, it flows past the outer side of the inner plate 7, which can cool the inner plate 7. Since the inner plate 7 is in contact with the battery, the battery can also be cooled.

[0044] The outer side of the air vent 4 located at the rear of the main body 1 is designed to be flat. Preferably, the outer side of the last air vent 4 is designed to be flat, so that the air entering the air duct 8 can flow outward through the last air vent 4, increasing the airflow. Figure 6 As indicated by the middle arrow.

[0045] In this embodiment, since the cover plate 2 has a through slot 3, an upper plate is also installed above the cover plate 2. The upper plate is made of metal and is connected to the cover plate 2 with bolts to close the cover plate 2 and prevent water leakage from the slot when it rains. For electric vehicles with metal foot pads, the metal foot pads are generally placed on the upper part of the cover plate 2, and the upper plate can be omitted.

[0046] In a further embodiment, a partition 9 is fixedly installed on the inner bottom of the main body 1. The partition 9 is preferably a plate-like structure made of metal. The partition 9 divides the space between the two inner plates 7 into multiple independent battery compartments. Depending on the actual number of batteries, for example, an electric vehicle with four batteries is divided into four independent battery compartments, and an electric vehicle with five batteries is divided into five independent battery compartments. Figure 4 and Figure 5 As shown, the two ends of the separator 9 penetrate the inner plate 7 and are located in the air duct 8. The two ends of the separator 9 do not contact the inner side wall of the main body 1 to ensure that the air duct 8 is a continuous structure. When the battery is placed inside an independent battery compartment, the separator 9 contacts the side wall of the battery, separating multiple batteries and facilitating heat dissipation between them. The heat from the battery is also directly transferred to the separator 9. When the air flows in the air duct 8, it can cool the two ends of the separator 9, thereby cooling the battery.

[0047] In a further embodiment, the partition 9 is designed as a double-layered metal plate structure, such as... Figure 7 and Figure 8 As shown, ventilation slots are formed between the double-layered metal plates. When the air enters the air duct 8, it can also flow in the ventilation slots, which can better dissipate heat from the partition 9. Since the battery is in contact with the partition 9, the battery can be cooled down quickly.

[0048] In a further embodiment, the bottom of the main body 1 at the air duct 8 has evenly spaced through holes 6. When riding, the electric bicycle often experiences up-and-down bumps or vibrations. During these bumps or vibrations, air can enter through the through holes 6, improving the heat dissipation effect of the air duct 8. Simultaneously, if rainwater enters the air duct 8 through the air holes 4 during riding, the through holes 6 also serve a drainage function, allowing water droplets to fall downwards. Due to the barrier effect of the inner plate 7, rainwater almost never falls onto the battery. Furthermore, the electric bicycle is equipped with a plastic outer shell, which also serves to protect against rain, so rainwater generally does not enter the main body 1.

[0049] This design allows for different sizes to be set for different types of electric bicycles (taking a four-battery electric bicycle as an example). Most common electric bicycles on the market place the battery under the seat or footrest. Figure 11The image shows an electric vehicle with the battery placed under the seat. Due to limited space under the seat, the batteries are often arranged in staggered layers. Therefore, in this embodiment, for this type of electric vehicle, the main body 1 is designed as two units, each capable of holding two batteries. Figure 12 As shown, the two main bodies 1 are staggered vertically, and a vent 10 is provided on the shell of the electric bicycle seat. When riding, air can enter the vent, allowing more airflow to enter the main body 1.

[0050] For electric bicycles with pedals located below the pedals, such as Figure 9 As shown, the main body 1 is designed as an integral structure, with four batteries inside. The main body 1 is fixed to the frame of the pedal by bolts, and a ventilation opening 10 (not shown in the figure) is also provided on the outer shell of the electric vehicle at the pedal.

[0051] When installing the battery, in order to ensure that the battery is placed more securely between the two inner plates 7, one of the inner plates 7 can be slid to the required position first, and then the battery can be placed in, with one side of the battery in contact with the inner plate 7. This will ensure that the battery is placed more neatly. After placement, the other inner plate 7 can be slid and in contact with the battery. Then the cover plate 2 can be covered and fixed, and the bolts can be inserted into the waist-shaped groove 3 to fix the inner plate 7.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
