Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery technology, and in particular to an electric sightseeing vehicle with a quick-change battery. Background Technology

[0002] As a core mode of transportation in scenic areas and parks, the range of electric sightseeing vehicles directly impacts operational efficiency. Traditional electric sightseeing vehicles often employ fixed battery layouts, requiring the removal of numerous fasteners and the use of specialized tools for battery replacement, making the process cumbersome and time-consuming. Especially during peak hours, the frequent need for battery replacements exposes the following technical pain points: First, battery pack installation and positioning rely on manual visual inspection and repeated adjustments, easily leading to misalignment or loose connections, resulting in poor circuit contact; second, the sliding battery compartment lacks multi-dimensional limiting design, making it susceptible to battery pack displacement due to vehicle vibrations, posing a safety hazard; third, the rigid connection structure struggles to withstand road bumps and impacts, and the battery interface is prone to metal fatigue due to stress concentration, shortening the lifespan of electrical components.

[0003] In existing technologies, some improvements attempt to enhance installation efficiency by adding guide grooves or snap-fit ​​structures, but single-plane positioning cannot effectively constrain the three-dimensional degrees of freedom of the battery pack. Some designs employ elastic locking devices, but lack a feedback mechanism for proper alignment during assembly, requiring operators to repeatedly confirm the installation status. Furthermore, the traditional method of replacing the entire battery pack results in high maintenance costs; when a partial battery cell fails, the entire module must be replaced, leading to resource waste.

[0004] To address the aforementioned issues, a novel battery quick-change system is urgently needed to achieve efficient assembly and disassembly while ensuring installation accuracy. An ideal solution should possess a self-centering guiding structure, multi-dimensional constraint mechanisms, and dynamic buffering functions. This would simplify the operation process, adapt to stability requirements under complex operating conditions, and provide technical support for the sustainable operation of electric sightseeing vehicles. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an electric sightseeing vehicle with a quickly replaceable battery, thus solving the technical problem of installation efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An electric sightseeing vehicle with a quick-swap battery, including

[0010] The frame serves as the chassis of the sightseeing vehicle. A battery replacement assembly is located in the middle of the frame, and a battery mounting plate is installed on the outside of the battery replacement assembly. The battery mounting plate is fixed with locking screws. The battery mounting plate is a tapered structure cover with protrusions on the upper and lower sides. Corresponding tapered grooves are provided on the outer side of the frame on the upper and lower sides. The initial fixation is achieved by matching the shape with the grooves. Then, the battery mounting plate is fixed to the outer side of the frame with locking screws.

[0011] Preferably, the battery replacement assembly includes a mounting frame, which is a hollow square frame with an opening on one side. Two sets of inner slides are provided below the mounting frame, through which two battery packs are slidably mounted.

[0012] Preferably, the battery pack has two sets of rollers below it, with six rollers arranged in three sets on each side. Multiple support points allow for sliding while ensuring stability. The battery pack also contains multiple battery structures that can be assembled.

[0013] Preferably, since the installation of the battery pack as a whole cannot better determine the internal positioning, a positioning component is provided on the inner side of the mounting frame. The positioning component includes a limiting groove and a limiting block, and the limiting groove is located on the inner side of the mounting frame.

[0014] Preferably, a limiting block is provided on the outer side of the corresponding battery pack. The limiting groove is a semi-circular groove structure, and the corresponding limiting block is a semi-circular protrusion. The battery pack is fixed and limited in the mounting frame by inserting the limiting block into the limiting groove.

[0015] Preferably, a buffer bolt is provided at the end of the limiting groove. The buffer bolt is a horizontal buffer spring structure to limit the insertion mileage of the battery pack.

[0016] Preferably, an inner locking block is provided inside the locking screw. The inner locking block is a raised arc-shaped structure. The inner locking block contacts the outer side of the battery pack. By using the locking screw in conjunction with the inner locking block, the battery pack is pushed inward, thereby limiting the position of the battery pack on both sides. In addition, the position of the limiting block is limited by the limiting groove on the other side, further limiting the position of the battery pack on both sides and improving the convenience of installation.

[0017] (III) Beneficial Effects

[0018] 1. Composite positioning system: The tapered groove on the outer side of the frame matches the upper and lower tapered protrusions of the battery mounting plate to achieve coarse positioning; when the battery pack is pushed into the mounting frame, its outer limiting block (semi-circular protrusion) slides along the limiting groove (semi-circular groove). When the limiting block contacts the buffer bolt (horizontal buffer spring), the spring resistance suddenly increases to provide tactile feedback, indicating that the installation is in place. The locking screw presses the battery mounting plate through the inner snap-fit ​​block (arc-shaped protrusion) to eliminate assembly gaps.

[0019] 2. Multi-directional constraint mechanism: The battery pack slides along the inner slide rail via three rollers (three sets symmetrically on both sides) at the bottom, providing bottom support; when the locking screw is tightened, the inner locking block applies pressure to the side of the battery pack, forming a three-dimensional clamping with the longitudinal constraint of the limiting groove on the limiting block. The six-point layout of the rollers and the slide rail work together to disperse vibration loads, and the arc-shaped inner locking block avoids local stress concentration.

[0020] 3. Modular design: The battery pack consists of multiple modular units. When replacing it, simply push it in along the tapered groove of the frame. The self-aligning characteristics of the limiting block and the limiting groove allow for tolerance. After the limiting block slides into the end of the limiting groove, tightening the locking screw on one side will complete the fixation. No tools are required throughout the process.

[0021] 4. Intelligent Buffer System: The spring structure of the buffer bolt compresses and stores energy when the battery pack is inserted to offset the impact of vehicle bumps; the end of the limiting groove has a reserved expansion gap, and when the battery pack is thermally deformed, the elastic deformation of the buffer bolt compensates for the displacement, keeps the contact pressure of the electrical connector stable, and avoids metal fatigue caused by rigid friction.

[0027] This application provides an electric sightseeing vehicle with a quick-change battery, which solves the problem of installation efficiency in the prior art. The battery pack is composed of multiple modular units. When replacing the battery, it is only necessary to push it in along the tapered groove of the frame. The self-aligning characteristics of the limiting block and the limiting groove allow for tolerance. After the limiting block slides into the end of the limiting groove, the locking screw can be tightened on one side to complete the fixation. No tools are required throughout the process.

[0028] Example 1

[0029] like Figure 1 As shown, the technical solution in this application embodiment is to solve the problem of low installation efficiency mentioned above, and the overall idea is as follows:

[0030] To address the problems existing in the prior art, this utility model provides an electric sightseeing vehicle with a quickly replaceable battery, including...

[0031] The vehicle frame 1 serves as the chassis of the sightseeing vehicle. A battery replacement assembly 2 is located in the middle of the frame 1, and a battery fixing plate 3 is located on the outer side of the battery replacement assembly 2. The battery fixing plate 3 is secured using locking screws 4. The battery fixing plate 3 is a tapered cover plate with protruding upper and lower sides. Correspondingly, tapered grooves are provided on the outer side of the frame 1 on both the upper and lower sides. Initial fixation is achieved by matching the shape with the grooves. Finally, the locking screws 4 secure the battery fixing plate 3 to the outer side of the frame 1.

[0032] like Figure 2-3 As shown, the battery replacement assembly 2 includes a mounting frame 21, which is a hollow square frame with an opening on one side. Two sets of inner slide rails 22 are provided below the mounting frame 21, through which two battery packs 23 are slidably mounted. Two sets of rollers 24 are provided below each battery pack 23, with six rollers arranged in three groups on both sides. Multiple support points ensure stability while allowing for sliding. The battery pack 23 contains multiple battery structures that can be assembled.

[0033] The installation of the battery pack 23 as a whole cannot accurately determine its internal positioning. A positioning component is provided on the inner side of the mounting frame 21. This component includes a limiting groove 26 and a limiting block 27. The limiting groove 26 is located on the inner side of the mounting frame 21, and the corresponding limiting block 27 is located on the outer side of the battery pack 23. The limiting groove 26 is a semi-circular groove structure, and the corresponding limiting block 27 is a semi-circular protrusion. The battery pack 23 is fixedly positioned within the mounting frame 21 by inserting the limiting block 27 into the limiting groove 26. A buffer bolt is provided at the end of the limiting groove 26. 25. The buffer bolt 25 is a horizontal buffer spring structure, which limits the insertion range of the battery pack 23. In addition, an inner locking block 5 is provided inside the locking screw 4. The inner locking block 5 is a raised arc-shaped structure. The inner locking block 5 contacts the outer side of the battery pack 23. The battery pack 23 is pushed inward by the locking screw 4 in conjunction with the inner locking block 5, which limits the position of the battery pack 23 on both sides. In addition, the position of the limiting block 27 is limited by the limiting groove 26 on the other side, which further limits the position of the battery pack 23 on both sides and improves the convenience of installation.

[0034] Technical effects:

[0035] 1. Composite positioning system; The tapered groove on the outer side of the frame 1 matches the upper and lower tapered protrusions of the battery mounting plate 3 to achieve coarse positioning; When the battery pack 23 is pushed into the mounting frame 21, its outer limiting block 27 (semi-circular protrusion) slides along the limiting groove 26 (semi-circular groove). When the limiting block 27 contacts the buffer bolt 25 (horizontal buffer spring), the spring resistance suddenly increases to provide tactile feedback, indicating that the installation is in place. The locking screw 4 presses the battery mounting plate 3 through the inner snap-fit ​​block 5 (arc-shaped protrusion) to eliminate assembly gaps.

[0036] 2. Multi-directional constraint mechanism: The battery pack 23 slides along the inner slide rail 22 via six rollers 24 at the bottom (three sets symmetrically on both sides), providing bottom support; when the locking screw 4 is tightened, the inner locking block 5 applies pressure to the side of the battery pack 23, forming a three-dimensional clamping with the longitudinal constraint of the limiting groove 26 on the limiting block 27. The six-point layout of the rollers 24 cooperates with the slide rail 22 to disperse vibration load, and the arc-shaped inner locking block 5 avoids local stress concentration.

[0037] 3. Modular design:

[0038] The battery pack 23 is composed of multiple modular units. When replacing it, it only needs to be pushed in along the tapered groove of the frame 1. The self-aligning characteristics of the limiting block 27 and the limiting groove 26 allow for a tolerance of ±3mm. After the limiting block 27 slides into the end of the limiting groove 26, the locking screw 4 can be tightened on one side to complete the fixation. No tools are required throughout the process.

[0039] 4. Intelligent buffer system: The spring structure of the buffer bolt 25 compresses and stores energy when the battery pack 23 is inserted to offset the impact of vehicle bumps; the end of the limiting groove 26 is reserved with an expansion gap. When the battery pack 23 is thermally deformed, the elastic deformation of the buffer bolt 25 compensates for the displacement, keeps the contact pressure of the electrical connector stable, and avoids metal fatigue caused by rigid friction.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
