Description

Technical Field

[0001] This utility model belongs to the technical field of new energy electric vehicles, and in particular relates to a modular assembly and positioning structure for new energy electric vehicle batteries. Background Technology

[0002] In recent years, the electric vehicle industry has shown a booming development trend, with the market size continuing to grow. Electric vehicles, with their convenience, economy, and environmental friendliness, are widely favored by urban residents, students, and delivery personnel, becoming an important tool for daily travel. Especially with the increasing environmental awareness and government support for green travel, the market demand for electric vehicles has further expanded. Electric vehicles move through motors, which require high voltage to drive. The voltage of a single battery cannot meet this demand. By connecting batteries in parallel or series-parallel configurations, the total capacity of the battery pack can be increased to achieve the goal of driving the motor with high voltage. In the process of connecting batteries in parallel or series-parallel configurations, modular assembly and positioning of the batteries are required. However, the following problems still exist in the current battery positioning process: Currently, the mainstream battery assembly and positioning methods on the market are basically to set up a battery slot, place the battery neatly into the battery slot, and then use a pressure plate to fix the top of the battery. If the electric vehicle is driven on a bumpy road, the battery is prone to shifting horizontally, which may cause short circuits and affect the rider's experience. When assembling a battery, the positive and negative terminals of the battery must be aligned in the same direction. However, the battery compartment usually does not indicate the battery orientation. Beginners may confuse the battery orientation when assembling the battery, which may lead to a short circuit. Batteries are usually placed side by side. The heat generated during operation cannot be dissipated when adjacent batteries are in contact, leading to heat accumulation, which in turn causes the local temperature of the battery to rise, the battery performance to deteriorate, and the battery life to be reduced. To address these issues, we provide a modular assembly and positioning structure for new energy electric vehicle batteries. Utility Model Content

[0003] The purpose of this utility model is to provide a modular assembly and positioning structure for batteries of new energy electric vehicles. By setting up a loading box, limiting block, positioning component, pressure plate, negative electrode mark, positive electrode mark and heat dissipation component, it solves the problems of battery displacement when driving on bumpy roads, confusion of battery orientation during battery assembly, and difficulty in heat dissipation of adjacent parts of adjacent batteries.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a modular assembly and positioning structure for a new energy electric vehicle battery, including a loading box, a positioning component, a pressure plate, and a heat dissipation component; the bottom of the loading box is fixedly connected with equidistantly distributed limiting blocks, the top of the limiting blocks is fixedly connected with the positioning component, and the top two sides of the loading box are fixedly connected with marking ears, one of the marking ears is fixedly connected with equidistantly distributed negative electrode markings, the other marking ear is fixedly connected with equidistantly distributed positive electrode markings, and the top of the loading box is provided with an inverted U-shaped pressure plate located above the positioning component; When assembling the battery, align the negative terminal (usually marked in blue) with the negative terminal mark and the positive terminal (usually marked in red) with the positive terminal mark, place the battery into the loading box, and then press the pressure plate on top of the battery to complete the battery loading process. The positioning assembly includes two positioning plates, with a reinforcing rib fixedly connected between the two positioning plates. A heat dissipation assembly is provided above the side of the loading box near the positive electrode mark, with equidistantly distributed heat dissipation components. The heat dissipation assembly includes an L-shaped air inlet pipe, with a U-shaped air outlet pipe fixedly connected to the bottom of the vertical part of the air inlet pipe, and an L-shaped air blower pipe fixedly connected to the top of the end of the air outlet pipe away from the air inlet pipe. The horizontal part of the air blower pipe extends between two adjacent positioning plates. The horizontal part of the air intake pipe faces the direction of the electric vehicle's movement and extends through the outer shell of the electric vehicle. During the electric vehicle's movement, the flowing air enters the heat dissipation component through the air intake pipe, and then enters the gap between the battery through the air duct and the air blower to dissipate heat.

[0005] Furthermore, rubber gasket 1 is fixedly connected to both inner end walls of the loading box, and rubber gasket 2 is fixedly connected to the side of the two positioning plates of each positioning component that are far apart. The first rubber pad cushions the impact between the two batteries on the edge and the loading box when they vibrate on bumpy roads, while the second rubber pad cushions the impact between the batteries and the positioning components.

[0006] Furthermore, a support plate is fixedly connected to the top of the side wall of the loading box near the positive electrode mark, and the air duct is fixedly connected to the support plate in a through manner; the support plate provides support for the heat dissipation assembly.

[0007] Furthermore, a water outlet pipe is fixedly connected to the lower end of the air intake pipe, and a similar marking ear is connected to the bottom end of the water outlet pipe; when heat dissipation is performed, if water accidentally enters the heat dissipation component from the air intake pipe, the water will be discharged from the water outlet pipe, without affecting the normal operation of heat dissipation.

[0008] Furthermore, both ends of the top of the loading box are fixedly connected to fixed ears that are fixedly connected to the marking ears. The top of the fixed ears is fixedly connected to a stud. The opposite sides of the vertical part of the pressure plate are fixedly connected to plug ears. The plug ears are provided with plug holes. The top of the stud passes through the adjacent plug holes and is screwed with a nut. After placing the battery in the loading box, pass the stud through the insertion hole on the insertion lug, and then tighten the nut to secure the battery.

[0009] Furthermore, the bottom end of the pressure plate is fixedly connected with equidistantly distributed rubber pads three, the height of which is greater than the diameter of the wire; The rubber pad three provides cushioning against collisions between the pressure plate and the battery. At the same time, since the height of the rubber pad three is greater than the diameter of the wire, it will not affect the series and parallel connections between the batteries.

[0010] This utility model has the following beneficial effects: This invention solves the problem of battery displacement by setting up a loading box, limiting blocks, positioning components, and a pressure plate. The battery is placed between the limiting blocks in the loading box, and the loading box, limiting blocks, and positioning components limit the battery in the horizontal direction to prevent it from shifting horizontally. After the battery is placed, the pressure plate is used to press the battery down to prevent it from shifting vertically, thus achieving the goal of preventing the battery from shifting even when driving on bumpy roads.

[0011] This invention solves the problem of novice users confusing the orientation when assembling batteries by setting negative and positive markings. When placing the battery, align the negative terminal (usually marked in blue) with the negative marking and the positive terminal (usually marked in red) with the positive marking to unify the battery orientation and prevent short circuits.

[0012] This invention solves the problem of poor heat dissipation in adjacent battery areas by setting up a positioning component and a heat dissipation component. The two positioning plates of the positioning component separate the adjacent batteries. The heat generated by the batteries during operation enters the positioning component. The horizontal part of the air inlet pipe of the heat dissipation component runs through the outer shell of the electric vehicle and points in the direction of movement of the electric vehicle. During the movement of the electric vehicle, air flows into the heat dissipation component from the air inlet pipe and blows into the interior of the positioning component to dissipate heat, thereby achieving the purpose of heat dissipation for adjacent battery areas.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-4 This utility model is a modular assembly and positioning structure for a new energy electric vehicle battery, including a loading box 1, a positioning component 2, a pressure plate 3, and a heat dissipation component 4; the bottom of the loading box 1 is fixedly connected with equidistantly distributed limiting blocks 106, the top of the limiting blocks 106 is fixedly connected with the positioning component 2, the top of the loading box 1 is fixedly connected with two marking ears 101 on both sides, one marking ear 101 is fixedly connected with equidistantly distributed negative electrode markings 1011, the other marking ear 101 is fixedly connected with equidistantly distributed positive electrode markings 1012, and the top of the loading box 1 is provided with an inverted U-shaped pressure plate 3 located above the positioning component 2; When assembling the battery, align the negative terminal (usually marked in blue) with the negative terminal mark 1011 and the positive terminal (usually marked in red) with the positive terminal mark 1012, and place it into the loading box 1. Then, press the pressure plate 3 on top of the battery to complete the battery loading. The setting of the limiting block 106, the loading box 1, and the positioning component 2 limits the lower part of the battery in the horizontal direction, the vertical part of the pressure plate 3 limits the upper part of the battery in the horizontal direction, and the horizontal part of the pressure plate 3 and the loading box 1 limit the battery in the vertical direction to prevent the battery from shifting when the electric vehicle travels on bumpy roads.

[0026] Among them, such as Figure 5 , Figure 6 As shown, rubber gaskets 105 are fixedly connected to both inner end walls of the loading box 1, and rubber gaskets 203 are fixedly connected to the opposite side of the two positioning plates 201 included in each positioning component 2. The rubber pad 105 is designed to cushion the collision between the two batteries at the edge and the loading box 1. The rubber pad 203 is designed to cushion the collision between the battery and the positioning component 2, preventing battery damage and electrolyte leakage.

[0027] Among them, such as Figure 2 , Figure 8As shown, both ends of the top of the loading box 1 are fixedly connected to the fixing ears 102 that are fixedly connected to the marking ears 101. The top of the fixing ears 102 is fixedly connected to the studs 103. The vertical parts of the pressure plate 3 are fixedly connected to the plug ears 301 on opposite sides. The plug ears 301 are provided with plug holes 303. The top of the studs 103 passes through the adjacent plug holes 303 and is screwed with nuts 107. The fixing lug 102, stud 103 and nut 107 provide a fixing environment for the pressure plate 3. After the battery is placed in the loading box 1, the stud 103 is passed through the insertion hole 303 on the insertion lug 301, and then the nut 107 is tightened to fix the battery in the vertical direction.

[0028] Among them, such as Figure 8 As shown, the bottom end of the pressure plate 3 is fixedly connected with rubber pads 302 that are evenly distributed. The height of the rubber pads 302 is greater than the diameter of the wire. Rubber pad 302 provides cushioning against collisions between pressure plate 3 and battery. At the same time, since the height of rubber pad 302 is greater than the diameter of wire, when wiring, the wire passes through the gaps between rubber pads 302 to connect the battery in series and parallel.

[0029] The working principle of this embodiment is as follows: When assembling the battery, align the negative terminal (usually marked in blue) with the negative terminal mark 1011 and the positive terminal (usually marked in red) with the positive terminal mark 1012, and place the battery into the groove between the limiting blocks 106 in the loading box 1. After the battery is stably placed, use wires to connect the battery in series and parallel. Pass the stud 103 through the insertion hole 303 on the insertion ear 301, adjust the position of the wires so that the wires are not pressed by the rubber pad 302 and are neatly arranged. Then tighten the nut 107 so that the rubber pad 302 is close to the upper part of the battery to fix the battery. The battery assembly is then completed. The setting of the limiting block 106, the loading box 1 and the positioning component 2 limits the lower part of the battery in the horizontal direction, the vertical part of the pressure plate 3 limits the upper part of the battery in the horizontal direction, and the horizontal part of the pressure plate 3 and the loading box 1 limit the battery in the vertical direction to prevent the battery from shifting when the electric vehicle is driven on bumpy roads. Specific Implementation Example 2

[0030] Please see Figure 6 , Figure 7Based on the first specific embodiment, the positioning component 2 includes two positioning plates 201, and a reinforcing rib 202 is fixedly connected between the two positioning plates 201. A heat dissipation component 4 is provided above the side of the loading box 1 near the positive electrode mark 1012. The heat dissipation component 4 includes an L-shaped air inlet pipe 401. A U-shaped air outlet pipe 402 is fixedly connected through the bottom of the vertical part of the air inlet pipe 401. An L-shaped air blower pipe 403 is fixedly connected through the top of the end of the air outlet pipe 402 away from the air inlet pipe 401. The horizontal part of the air blower pipe 403 extends into the space between two adjacent positioning plates 201. The two positioning plates 201 separate adjacent batteries, preventing heat generated by adjacent batteries during operation from accumulating between adjacent surfaces. The reinforcing ribs 202 connect the two positioning plates 201, enhancing the stability of the positioning plates 201. The horizontal part of the air inlet pipe 401 faces the forward direction of the electric vehicle and extends through the outer shell of the electric vehicle. During the movement of the electric vehicle, the flowing air enters the heat dissipation component 4 through the air inlet pipe 401, and enters the gap between adjacent batteries through the air duct 402 and the air blower 403, and then continues to move to carry away the heat generated by the battery during operation.

[0031] Among them, such as Figure 3 As shown, a support plate 104 is fixedly connected to the top of the side wall of the loading box 1 near the positive electrode mark 1012, and the air duct 402 is fixedly connected to the support plate 104 in a through manner; the support plate 104 provides support for the heat dissipation assembly 4.

[0032] Among them, such as Figure 3 , Figure 7 As shown, a water outlet pipe 404 is fixedly connected to the lower end of the air duct 402, and the bottom end of the water outlet pipe 404 is connected to a similar marking ear 101.

[0033] The working principle of this embodiment is as follows: the battery only needs to work (to power the motor) when the electric vehicle is moving. During the movement of the electric vehicle, the flowing air enters the heat dissipation component 4 through the air inlet pipe 401, and enters the gap between adjacent batteries through the air duct 402 and the air blower 403. Then, it continues to move and removes the heat generated by the battery during operation. If water accidentally enters the heat dissipation component 4 through the air inlet pipe 401 during the heat dissipation operation, the water will flow into the air duct 402 along the air inlet pipe 401, and flow to the lower end of the air duct 402 under the action of gravity and be discharged from the water outlet pipe 404. Due to the U-shaped arrangement of the air duct 402 and the location of the water outlet pipe 404 at the lower end of the air duct 402, even if the water flow rate is very high, it will not enter the air blower 403. The water discharge will not affect the normal operation of the heat dissipation.

[0034] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
