Description

Technical Field

[0001] This invention relates to a battery positioning device, and more particularly to a battery positioning device for rapid battery swapping of electric mining trucks. Background Technology

[0002] Compared with traditional diesel mining trucks, pure electric mining trucks have advantages such as zero emissions, no pollution, energy saving and environmental protection, and low operating costs. At the same time, pure electric mining trucks use an electronic control system, which makes it easier to realize the intelligent transformation of equipment and lays the foundation for mine information management and unmanned operation.

[0003] The pure electric mining truck has two range modes: charging and battery swapping. In charging mode, the vehicle needs to be driven to a charging location to charge, and it cannot work while charging. It can only wait for the battery to be fully charged or for multiple electric mining trucks to work and charge in turn, which will reduce work efficiency or increase costs. In battery swapping mode, the vehicle can quickly reach full charge by directly replacing the battery.

[0004] In view of the above, the present invention designs a battery positioning device with a simple structure that meets the requirements of rapid battery swapping.

[0005] While this battery swapping model can effectively solve the problem of excessively long charging times for electric vehicles, it still has the following drawbacks:

[0006] 1. The lack of dedicated battery swapping stations in mining environments makes it difficult to achieve precise horizontal and stable positioning of mining trucks. During battery swapping, repeated attempts and multiple fine adjustments are often required, leading to difficulties in battery positioning.

[0007] 2. Because the working surface of a mine is usually uneven, with lots of gravel, and is easily loose or slippery, the electric mining truck will experience severe bumps when running, which can easily lead to poor battery contact.

[0008] The information disclosed in this background section is intended only to enhance understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of existing technologies, such as difficulty in battery positioning and the tendency for poor battery contact, and to provide a battery positioning device for rapid battery swapping in electric mining trucks that can quickly position the battery while avoiding poor battery contact.

[0010] To achieve the above objectives, the technical solution of the present invention is:

[0011] A battery positioning device for rapid battery swapping of electric mining trucks, the battery positioning device comprising: a positioning bracket, a guide block and a power supply base;

[0012] The positioning bracket is a semi-enclosed bracket used to accommodate the battery of the electric mining truck. The top and one side of the positioning bracket have openings to facilitate the entry and exit of the battery.

[0013] Guide blocks are provided at both ends of the positioning bracket, and the guide blocks at both ends of the positioning bracket are arranged opposite to each other. The positioning bracket guides and positions the battery through the guide blocks provided thereon.

[0014] The lower power supply seat is located on top of the positioning bracket and is elastically connected to the positioning bracket. The lower power supply seat is used to cooperate with the upper power supply seat on the battery.

[0015] The positioning bracket includes a bottom bracket, a connecting bracket, and two limiting brackets. The bottom of the connecting bracket and the two limiting brackets are fixedly connected to the top of the positioning bracket. The two limiting brackets are respectively disposed at both ends of the positioning bracket, and one of the opposite ends of the two limiting brackets is connected to the connecting bracket to form an integral structure.

[0016] The height of the connecting frame is greater than the height of the limiting frame.

[0017] The battery positioning device includes at least four guide blocks, which are symmetrically arranged on two limiting frames. The guide blocks have an inclined surface structure on the side near the center of the positioning bracket, and the inclination angle of the inclined surface of the guide block is 65 to 75 degrees.

[0018] The power supply base includes a power supply connector, a power supply bracket, and multiple springs. The power supply bracket is fixedly mounted on the top of one of the limiting frames. The top of the power supply bracket is fixedly connected to one end of each spring, and the other end of each spring is fixedly connected to the bottom of the power supply connector.

[0019] The battery positioning device further includes at least four positioning posts, which are respectively disposed on the top of the two limiting frames;

[0020] The battery has multiple positioning holes that mate with positioning posts, and the positioning posts are inserted into their corresponding positioning holes.

[0021] When the battery is located in the center of the bottom bracket, the positioning post is aligned with its corresponding positioning hole.

[0022] The bottom bracket includes two crossbeams and multiple longitudinal beams. The two crossbeams are perpendicular to the limiting frame, and the multiple longitudinal beams are parallel to the limiting frame. The multiple longitudinal beams are evenly fixed on the top of the two crossbeams. The distance between adjacent longitudinal beams is greater than the width of the forklift forks, and the height of the longitudinal beams is greater than the thickness of the forklift forks.

[0023] Rubber pads are provided on the top of each of the longitudinal beams.

[0024] The top of the positioning post has a conical structure.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. In this invention, a battery positioning device for rapid battery swapping of electric mining trucks utilizes a semi-enclosed positioning bracket to accommodate the battery. The guide block, located near the center of the positioning bracket, has an inclined structure. During battery swapping, a connecting frame limits the battery's forward and backward movement, while the limiting frame roughly positions the battery in the left and right directions. As the battery falls, the guide block automatically guides it, ensuring accurate placement within the positioning device. Therefore, this design enables rapid battery positioning through automatic battery guidance by the guide block.

[0027] 2. In the battery positioning device for rapid battery swapping of electric mining trucks of the present invention, the lower power supply seat includes a power supply connector, a power supply bracket, and multiple springs. After battery swapping, the upper power supply seat on the battery mates with the lower power supply seat, compressing the springs. When the electric mining truck experiences bumps, the elastic force provided by the springs and the weight of the battery itself ensure a tight connection between the upper and lower power supply seats, preventing poor battery contact. Therefore, this design effectively avoids poor battery contact by using the elastic force provided by the springs and the weight of the battery to ensure a tight connection between the upper and lower power supply seats.

[0028] 3. In the battery positioning device for rapid battery swapping of electric mining trucks of the present invention, the positioning bracket is a semi-enclosed bracket, and multiple longitudinal beams are arranged parallel to the limiting frame. The distance between adjacent longitudinal beams is greater than the width of the forklift forks, and the height of the longitudinal beams is greater than the thickness of the forklift forks. This allows the battery to directly enter the positioning bracket from the opening side. At the same time, when the battery falls, the forklift forks can enter the gaps between the longitudinal beams, which facilitates the quick extraction of the forklift forks, thereby effectively improving the battery swapping efficiency.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1:

[0035] See Figure 1 A battery positioning device for rapid battery swapping of electric mining trucks is disclosed. The battery positioning device includes: a positioning bracket 1, guide blocks 2, and a power supply base 3. The positioning bracket 1 is a semi-enclosed bracket used to accommodate the battery 4 of the electric mining truck. The top and one side of the positioning bracket 1 have openings to facilitate the entry and exit of the battery 4. Guide blocks 2 are provided at both ends of the positioning bracket 1, and the guide blocks 2 at both ends of the positioning bracket 1 are arranged opposite to each other. The positioning bracket 1 guides and positions the battery 4 through the guide blocks 2. The power supply base 3 is located on the top of the positioning bracket 1 and is elastically connected to the positioning bracket 1. The power supply base 3 is used to connect with the power supply on the battery 4. The upper seat 41 is fitted; the positioning bracket 1 includes a bottom bracket 11, a connecting bracket 12 and two limiting brackets 13. The bottom of the connecting bracket 12 and the two limiting brackets 13 are fixedly connected to the top of the positioning bracket 1. The two limiting brackets 13 are respectively set at both ends of the positioning bracket 1. One of the opposite ends of the two limiting brackets 13 is connected to the connecting bracket 12 to form an integral structure. The height of the connecting bracket 12 is greater than the height of the limiting bracket 13. The battery positioning device includes at least four guide blocks 2. The at least four guide blocks 2 are symmetrically arranged on the two limiting brackets 13. The guide blocks 2 near the middle of the positioning bracket 1 have an inclined structure. The inclination angle of the inclined surface of the guide block 2 is 65 to 75 degrees.

[0036] When replacing the battery, the battery 4 is lifted by a forklift and roughly aligned with the central axis of the bottom bracket 11. Once it is confirmed that the width of the battery 4 does not exceed the limit brackets 13 on both sides, the forklift can be slowly moved forward. Since the height of the connecting bracket 12 is greater than the height of the limit bracket 13, the connecting bracket 12 can quickly position the battery 4. When the battery 4 is in contact with the inner side of the connecting bracket 12, the forklift stops moving forward and then slowly lowers the battery 4. During the descent, if there is a deviation in the left or right direction, the guide blocks 2 on both sides of the positioning device will automatically guide the battery 4 to center its position.

[0037] The battery positioning device further includes at least four positioning posts 5, which are respectively disposed on the top of the two limiting frames 13; the battery 4 is provided with a plurality of positioning holes 42 that cooperate with the positioning posts 5, and the positioning posts 5 are inserted into their corresponding positioning holes 42; when the battery 4 is located in the center of the bottom bracket 11, the positioning posts 5 are aligned with their corresponding positioning holes 42; the tops of the multiple longitudinal beams 15 are provided with rubber pads 16; the tops of the positioning posts 5 are tapered.

[0038] During the forklift-driven descent of the battery 4, the conical structure at the top of the positioning post 5 can engage with the positioning hole 42 on the battery 4 to further guide the battery 4. At the same time, when the battery 4 has completely fallen, the positioning post 5 and the positioning hole 42 engage tightly to position the battery 4.

[0039] Example 2:

[0040] Example 2 is basically the same as Example 1, except that:

[0041] The power supply lower seat 3 includes a power supply connector 31, a power supply bracket 32 ​​and multiple springs 33. The power supply bracket 32 ​​is fixedly installed on the top of one of the limiting brackets 13. The top of the power supply bracket 32 ​​is fixedly connected to one end of each spring 33, and the other end of each spring 33 is fixedly connected to the bottom of the power supply connector 31.

[0042] The power supply mount 41 on battery 4 mates with the power supply connector 31 and compresses the spring 33. When the electric mining truck experiences bumps, the elastic force provided by the spring 33 and the weight of the battery 4 itself can ensure a tight connection between the power supply mount 41 and the power supply connector 31, preventing poor contact of the battery 4. Example 3:

[0043] Example 3 is basically the same as Example 2, except that:

[0044] The bottom bracket 11 includes two crossbeams 14 and multiple longitudinal beams 15. The two crossbeams 14 are both perpendicular to the limiting frame 13, and the multiple longitudinal beams 15 are both parallel to the limiting frame 13. The multiple longitudinal beams 15 are evenly fixed on the top of the two crossbeams 14. The distance between adjacent longitudinal beams 15 is greater than the width of the forklift forks, and the height of the longitudinal beams 15 is greater than the thickness of the forklift forks.
