Description

Technical Field

[0001] This utility model relates to the field of battery compartment limiting structure technology, and in particular to a battery limiting mechanism and an electric vehicle. Background Technology

[0002] Due to inadequate charging infrastructure and unstable power supply, riders generally rely on battery swapping for energy replenishment, which involves quickly replacing battery packs to extend their range. Under this model, users frequently need to switch between battery packs manufactured by different companies and carriers, and these batteries vary in size and shape.

[0003] To ensure stable battery positioning during driving, existing electric vehicles typically incorporate a limiting structure in the battery compartment for lateral or longitudinal positioning. Current mainstream technologies often employ rigid metal components for this limiting structure, which are welded to the inside of the battery compartment. This design is simple and low-cost, making it widely used in early electric vehicles. However, because welded limiting blocks have fixed dimensions, they can only accommodate specific battery pack models or specifications, resulting in poor compatibility.

[0004] In real-world usage scenarios, when riders replace batteries with non-original or different-sized ones, the battery and the limiting structure cannot form an effective fit, causing the battery to wobble significantly during vehicle operation. This mechanical vibration not only accelerates wear between the battery's electrical connector and the vehicle's interface, affecting contact reliability, but can also cause momentary power outages, signal interruptions, and other malfunctions, seriously threatening driving safety. Furthermore, to accommodate different batteries, users must manually remove the original limiting block or replace the entire battery bracket, a process requiring specialized tools and considerable time, significantly reducing the efficiency of battery swapping operations and failing to meet the practical demands for high-frequency, rapid battery swapping services. Utility Model Content

[0005] The purpose of this invention is to provide a battery limiting mechanism and an electric vehicle to alleviate the technical problem that the limiting structure of the battery compartment in the prior art cannot be applied to batteries of different sizes.

[0006] In the first aspect, the battery limiting mechanism provided by this utility model includes: a battery base, a battery pressure plate, and a pressing elastic element; The battery base and the battery pressure plate are spaced apart from each other. The surfaces of the battery base and the battery pressure plate opposite each other are provided with a first limiting member and a second limiting member. The first limiting member, the second limiting member and the battery pressure plate form a limiting space. The first limiting member is slidably connected to the battery base along a first direction, and the second limiting member is slidably connected to the battery base along a second direction. The battery pressure plate is configured to be movable relative to the vehicle frame body along a third direction to adjust the size of the limiting space. The first direction, the second direction, and the third direction are set perpendicularly to each other; The bottom of the battery pressure plate is provided with a plurality of the aforementioned clamping elastic elements. The battery pressure plate is configured to rotate relative to the main body of the vehicle frame, so that during the process of the battery body being installed and pushed into the battery base, the rotation of the battery pressure plate causes the clamping elastic elements to clamp the battery body.

[0007] In an optional implementation, When the battery body is installed, the battery body is pushed into the battery base along the first direction; The compression elastic element includes a front elastic element and a rear elastic element, which are spaced apart along the first direction.

[0008] In an optional implementation, The rotation fulcrum of the battery pressure plate relative to the main body of the vehicle frame is located between the front elastic member and the rear elastic member, and the rotation fulcrum is set closer to the front elastic member than the rear elastic member, so that in the natural state, the horizontal height of the rear elastic member is lower than that of the front elastic member. During the installation and pushing of the battery body into the battery base, it contacts the rear elastic member. The battery pressure plate rotates around the rotation fulcrum in a first rotation direction, so that the front elastic member rotates in the direction of pressing the battery body. During the removal of the battery body from the battery base, it disengages from the rear elastic member. The battery pressure plate rotates around the rotation fulcrum in a second rotation direction, so that the front elastic member rotates in the direction away from the battery body.

[0009] In an optional implementation, The battery limiting mechanism also includes a connecting component; The top of the battery pressure plate is provided with a hinge seat, and a mounting plate is rotatably connected to the hinge seat. One end of the connecting member is connected to the vehicle frame body, and the other end of the connecting member is rotatably connected to the mounting plate. The connecting member is provided with a vertical sliding path arranged along the third direction. The vertical sliding path is used to allow the mounting plate to slide relative to the connecting member, so that the battery pressure plate moves upward along the third direction.

[0010] In an optional implementation, The connecting components include a frame connecting plate and a pressure plate connecting plate; The frame connecting plate is connected to the top of the pressure plate connecting plate, and the frame connecting plate is used to connect to the frame body; The pressure plate connecting plate is provided with a vertical elongated hole, which forms the vertical sliding path. The end of the mounting plate is provided with a connector, which is configured to move within the vertical elongated hole.

[0011] In an optional implementation, The battery base is provided with a first lateral sliding path arranged along a first direction, and the first lateral sliding path is used to move the first limiting member relative to the battery base along the first direction. The battery base is provided with a second lateral sliding path arranged along a second direction, the second lateral sliding path being used to move the second limiting member relative to the battery base along the second direction.

[0012] In an optional implementation, The battery base is provided with a first transverse elongated hole arranged along a first direction, the first transverse elongated hole forming the first transverse sliding path, and the first limiting member is slidably connected to the first transverse elongated hole.

[0013] In an optional implementation, The battery base is provided with a second transverse elongated hole arranged along the second direction, the second transverse elongated hole forming the second transverse sliding path, and the second limiting member is slidably connected to the second transverse elongated hole.

[0014] In an optional implementation, The battery limiting mechanism also includes a battery compartment door; The battery compartment door is rotatably connected to the side of the battery base away from the first limiting member.

[0015] Secondly, the electric vehicle provided by this utility model includes the battery limiting mechanism.

[0016] The battery limiting mechanism provided by this utility model limits the battery body through a first limiting component, a second limiting component, and a battery pressure plate. Since the first limiting component can move in a first direction, the second limiting component can move in a second direction, and the battery pressure plate moves in a third direction, it can be applied to various battery bodies of different specifications. During the process of pushing the battery body into the battery base, the battery pressure plate can rotate, and the clamping elastic element rotates with the battery pressure plate, so that the clamping elastic element can clamp the battery body. When the battery body is fully in place, the clamping elastic element maintains the clamping state and automatically locks the battery body, effectively reducing battery vibration. It achieves three-dimensional limiting combined with elastic buffering, avoids the risk of dislodgement, and alleviates the technical problem that the limiting structure of the battery compartment in the prior art cannot be applied to batteries of different sizes.

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] like Figures 1-6As shown, the battery limiting mechanism provided in this embodiment includes a battery base 100 for supporting the battery body 10, a battery pressure plate 200 for limiting the battery body 10 in a third direction, and a plurality of pressing elastic members 300 disposed at the bottom of the battery pressure plate 200. The battery base 100 is provided with a first limiting member 400 and a second limiting member 500, wherein the first limiting member 400 is used to limit the battery body 10 in a first direction and can move relative to the battery base 100 in the first direction; the second limiting member 500 is used to limit the battery body 10 in a second direction and can move relative to the battery base 100 in the second direction.

[0025] The first direction is the installation and removal direction. The first direction, the second direction, and the third direction are perpendicular to each other, forming an orthogonal limiting structure in three-dimensional space, thereby achieving flexible adaptation and stable limiting of the battery body 10 in three dimensions.

[0026] The bottom of the battery pressure plate 200 is provided with multiple clamping elastic elements 300. The battery pressure plate 200 is configured to rotate relative to the main body of the vehicle frame, generating a lever rotational motion. This allows the battery pressure plate 200 to rotate and clamp the battery body 10 along with the clamping elastic elements 300 during the installation and pushing of the battery body 10 into the battery base 100, thereby achieving locking when the battery is installed in place.

[0027] When the battery body 10 is installed, the battery body 10 is pushed into the battery base 100 along the first direction; the clamping elastic member 300 includes a front elastic member 310 and a rear elastic member 320 arranged at intervals along the first direction. The front elastic member 310 and the rear elastic member 320 are respectively set at the front and rear positions of the bottom of the battery pressure plate 200, and can work together during the battery installation process to ensure a smooth transition of the clamping process.

[0028] Furthermore, the pivot point of the battery plate 200 relative to the frame body is located between the front elastic member 310 and the rear elastic member 320, and the pivot point is set closer to the front elastic member 310 than the rear elastic member 320, so that in the natural state, the horizontal height of the rear elastic member 320 is lower than that of the front elastic member 310.

[0029] Specifically, when the battery body 10 is pushed into the battery base 100 along the first direction, because the rear elastic member 320 is lower than the front elastic member 310, the rear end of the battery body 10 first contacts the rear elastic member 320 located behind the battery pressure plate 200. At this time, the battery pressure plate 200 rotates around its rotation fulcrum in the first rotation direction under the action of the contact force. Figure 5The counterclockwise rotation shown causes the front elastic element 310 to move towards the direction of pressing the battery body 10. As the battery body 10 continues to be pushed in, the rear elastic element 320 is deformed under pressure and drives the battery pressure plate 200 to rotate, causing the front elastic element 310 to move downwards and gradually press the top front area of ​​the battery body 10, achieving adaptive pressing. When the battery body 10 is fully in place, the pressing elastic element 300 remains compressed and continues to apply pressure, firmly fixing the battery body 10 in the battery base 100 to prevent loosening or detachment due to vibration or bumps during operation.

[0030] When it is necessary to remove the battery body 10, the reverse operation causes the battery body 10 to exit from the front end. The rear elastic element 320 disengages from the battery body 10, and the battery pressure plate 200 rotates in the second rotation direction under its own gravity or elastic restoring force. Figure 5 As shown, rotating clockwise causes the front elastic element 310 to lift upwards, releasing the clamping force on the battery body 10 and facilitating the easy removal of the battery.

[0031] To enable the battery pressure plate 200 to move and rotate freely in the third direction, the battery limiting mechanism also includes a connecting member 600. The top of the battery pressure plate 200 is provided with a hinge seat 210, and a mounting plate 220 is rotatably connected to the hinge seat 210. The mounting plate 220 is then connected to the vehicle frame body through the connecting member 600.

[0032] The connecting member 600 includes a frame connecting plate 610 and a pressure plate connecting plate 620. The frame connecting plate 610 is located on top and is fixedly connected to the frame body. The pressure plate connecting plate 620 is located on the bottom and has a vertical elongated hole 621. The vertical elongated hole 621 forms a vertical sliding path extending in a third direction.

[0033] The end of the mounting plate 220 is provided with a connector, which specifically includes a bolt and a nut. The bolt extends into the vertical elongated hole 621 and can slide up and down therein. The nut locks the position, so that the battery pressure plate 200 can adjust its position within the vertical range while still retaining the function of rotating around the hinge point, thus taking into account both the assembly tolerance adjustment and dynamic clamping requirements.

[0034] The battery base 100 is also provided with a first lateral sliding path and a second lateral sliding path, which are used to guide the first limiting member 400 and the second limiting member 500 to move along the first direction and the second direction respectively on the battery base. Specifically, the battery base 100 is provided with a first lateral elongated hole 110 extending along the first direction, and the first limiting member 400 achieves position adjustment by slidingly engaging with the first lateral elongated hole 110; similarly, a second lateral elongated hole 120 arranged along the second direction constitutes a second lateral sliding path, and the second limiting member 500 is slidably connected to it, so that the limiting position can be adjusted in the second direction. By adjusting the position of the two limiting members, battery bodies 10 of different lengths and widths can be adapted, improving the versatility of the limiting mechanism.

[0035] Both the first limiting component 400 and the second limiting component 500 are limiting block structures with inclined guide blocks. The limiting components can slide and lock with the transverse elongated hole through the connecting parts. The connecting parts can be threaded connecting parts such as bolts.

[0036] In addition, the battery limiting mechanism can also be equipped with a battery compartment door 700, which is rotatably connected to the side of the battery base 100 away from the first limiting member 400. This door can be closed after battery installation, further enhancing safety and preventing foreign objects from entering or accidentally touching the battery. The entire limiting structure achieves automatic battery clamping and release without the need for additional locking devices through a combination of mechanical linkage and elastic clamping, simplifying the disassembly and assembly process and improving maintenance convenience.

[0037] When applied to electric vehicles, this battery limiting mechanism effectively solves the problem of existing battery compartments being incompatible with multiple battery specifications and quantities. Through the design of a three-way adjustable limiting component and a rotatable battery pressure plate working in conjunction with the elastic element 300, flexible spatial constraint is achieved on the battery body 10. This ensures smooth installation and automatically establishes a reliable elastic clamping force after placement, significantly reducing the risk of battery displacement or loosening due to vibration during driving. The overall structure is compact, responsive, and highly adaptable, making it suitable for electric vehicles requiring frequent battery replacements or using multiple battery models.

[0038] Based on the above, the electric vehicle provided in this embodiment includes a battery limiting mechanism.

[0039] Since the technical effects of the electric vehicle provided in the above embodiments are the same as those of the battery limiting mechanism provided in the above embodiments, they will not be described again here.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
