Description

Technical Field

[0001] This utility model relates to the field of battery compartment locking, specifically to a rear-insertion battery compartment guide sliding locking structure. Background Technology

[0002] With the increasing popularity of electric bicycles, electric motorcycles, and other new energy vehicles, the installation and replacement methods of onboard batteries have become a crucial factor affecting user experience and vehicle maintenance efficiency. Existing battery compartments mostly employ top-plug or side-plug methods, typically requiring users to insert and remove the battery from above or the side of the vehicle. While these structures can meet the battery's needs for fixation and power supply to some extent, they still have many shortcomings.

[0003] First, traditional top-loading or side-loading battery compartments place high demands on vehicle space layout, especially in compact models where the top or side space is often occupied by other components, thus limiting the battery insertion direction. This not only increases design complexity but also makes it inconvenient for users to replace batteries routinely. For some models, users even need to remove the outer casing or foot pedal components before they can replace the battery.

[0004] Secondly, existing battery compartments lack effective guiding and clamping structures, making it easy for batteries to become misaligned or stuck during insertion and removal. This not only affects the smoothness of insertion and removal but may also cause wear and tear on the battery casing or battery compartment structure. During vehicle operation, if the battery is not sufficiently clamped and secured, it may vibrate and loosen, affecting the stability of electrical contacts and even leading to safety hazards.

[0005] Secondly, traditional battery compartments often use simple clips or screws for fixing, which lacks sufficient locking reliability. As vehicles travel on complex road conditions, the battery is prone to displacement due to vibration or impact. Although some products have added locking mechanisms, their structures are complex and bulky, and they are not optimized for rear insertion and removal operations, resulting in cumbersome operation and insufficient stability during use.

[0006] In summary, existing battery compartments generally suffer from the following defects: First, they lack rear insertion and removal capabilities, which limits the convenience of vehicle layout and user operation; second, the guiding and clamping structures are imperfect, resulting in instability during the insertion and removal process; and third, the locking methods are limited, failing to balance reliability and ease of operation. Summary of the Invention

[0007] To address the aforementioned problems, this invention provides a rear-mounted battery compartment guide sliding locking structure, which effectively overcomes the shortcomings of existing technologies.

[0008] This utility model is achieved through the following technical solution: a rear-mounted battery compartment guide sliding locking structure, comprising:

[0009] A battery bracket is fixedly mounted on the vehicle frame. The battery bracket has a battery cavity, and the power supply battery is inserted into the battery cavity in a rear-plug-in manner.

[0010] The rear lock body is located at the bottom of the battery cavity. After the power supply battery is fully inserted into the battery cavity, the rear lock body locks the power supply battery.

[0011] Guide clamping plates are disposed on both sides of the battery cavity to guide and clamp the power supply battery inserted into the battery cavity;

[0012] Guide rails are respectively disposed on both sides of the power supply battery, and a track cavity is formed between the guide rails. When the power supply battery is inserted into the battery cavity, the guide clamping piece is guided into the track cavity.

[0013] As a preferred technical solution, a knob block is provided on the outer end of the guide clamping plate, a locking screw is provided on the knob block, a nut is embedded in the battery bracket, and the knob block passes through the nut and is pressed against the guide clamping plate by the locking screw.

[0014] As a preferred technical solution, a guide pin is provided on each side of the guide clamping plate, and the guide clamping plate is axially mounted on the battery bracket through the guide pin.

[0015] As a preferred technical solution, a pressure cover is locked onto the end face of the guide rail away from the rear lock body, and the pressure cover is fixedly installed on the power supply battery by screws.

[0016] As a preferred technical solution, a baffle is also provided at the tail end of the battery bracket, and the power supply battery is limited after being inserted into the position of the baffle.

[0017] As a preferred technical solution, a lock hole is provided at the bottom of the tail end of the power supply battery, and the rear lock body rotates out the lock rod and inserts it into the lock hole.

[0018] As a preferred technical solution, the two sides of the guide clamping plate are tapered guide surfaces.

[0019] The beneficial effects of this utility model are: by setting guide clamping plates on both sides of the battery cavity, this utility model realizes a dual function in the battery insertion and removal process.

[0020] On the one hand, the guide clamping plate can guide the battery when it is inserted, so that the battery can smoothly enter the track cavity. This effectively avoids problems such as insertion and removal deviation and jamming caused by the lack of a guide structure in traditional battery compartments, and greatly improves the convenience and stability of battery insertion and removal.

[0021] On the other hand, after the battery is inserted into place, the guide clamping plate cooperates with the battery bracket through the knob block and locking screw to clamp and fix the battery, keeping the battery stable in the battery cavity and preventing loosening or displacement due to vibration during vehicle operation, thus ensuring the reliability of electrical contact and the safety of use.

[0022] Compared with traditional single guiding or locking structures, the guide clamping plate of this utility model organically combines guiding and clamping functions, ensuring smooth battery insertion while achieving reliable clamping and fixing. The structure is simple and compact, and easy to install and operate, which not only improves the user experience but also enhances the safety and stability of the vehicle during operation.

[0030] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0031] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0032] like Figures 1-4 As shown in the specific embodiment of this utility model, a rear-mounted battery compartment guide sliding locking structure is provided. This mechanism includes a battery bracket 2, which is fixedly mounted on the vehicle frame and serves as a support component for the power supply battery 1.

[0033] The battery bracket 2 has a battery cavity inside, the size and shape of which are designed according to the specifications of the power supply battery 1, allowing the power supply battery 1 to be inserted into the battery cavity from the rear of the frame. Unlike traditional top-plug or side-plug structures, this rear-plug method can make full use of the space at the rear of the frame, avoiding the problem of the upper or side of the frame being occupied, thereby improving the convenience of battery installation and removal and the compactness of the overall vehicle structure.

[0034] A rear lock body 8 is installed at the bottom of the battery compartment. The rear lock body 8 is used to reliably lock the power supply battery 1 that has been inserted into the compartment.

[0035] Specifically, when the power supply battery 1 is fully inserted into the battery cavity, the locking hole at the bottom of its tail end is aligned with the locking rod in the rear lock body 8. After the locking rod is rotated, it is pushed out and inserted into the locking hole of the power supply battery 1, thereby forming a stable mechanical lock. This structure ensures that the battery will not loosen due to vibration during driving, improving the battery's fixation reliability and safety during operation.

[0036] Guide clamping plates 6 are provided on both sides of the battery cavity. The guide clamping plates 6 not only guide the battery 1 during insertion, allowing the battery to enter the battery cavity smoothly along the correct path, but also apply clamping force to the battery after it is inserted into place, thereby ensuring a stable fit between the battery and the battery cavity. To further improve the operability of the structure, a knob block 7 is provided on the outer end of the guide clamping plate 6. The knob block 7 is provided with a locking screw 12, which can pass through the nut 11 embedded in the battery bracket 2.

[0037] When the knob block 7 is tightened, the locking screw 12 drives the guide clamping plate 6 to move towards the battery, so that the guide clamping plate 6 forms a stable clamping contact with the battery. This not only ensures the fixation of the battery in the track cavity 5, but also allows the user to install and remove the battery through simple knob operation, making the process convenient and quick.

[0038] The guide clamping plate 6 is mounted on the battery bracket 2 via guide pins 10. Each guide clamping plate 6 has guide pins 10 on both sides. The pins serve as fulcrums for rotation or sliding, enabling the guide clamping plate 6 to achieve reliable operation during the locking process.

[0039] Meanwhile, the two sides of the guide clamping plate 6 are designed as tapered guide surfaces. This shape can apply a gradually increasing guiding and clamping effect to the battery when it is inserted, so that the battery can automatically correct its position and enter the battery cavity stably, effectively avoiding the problem of tilting or jamming.

[0040] To further enhance the stability between the battery and the battery cavity, guide rails 4 are provided on both sides of the power supply battery 1, forming a track cavity 5 between the two guide rails 4. When the power supply battery 1 is inserted, the guide clamping piece 6 guides the battery along the track cavity 5, achieving double guidance. To prevent the battery from becoming loose at the insertion end, a pressure cap 3 is provided on the end face of the guide rail 4 away from the rear lock body 8. The pressure cap 3 is fixed to the power supply battery 1 with screws, forming a sealing and limiting effect, keeping the battery in a stable state within the track cavity 5.

[0041] In addition, a limiting stop 9 is provided at the tail end of the battery bracket 2. When the power supply battery 1 is inserted and reaches the position of the stop 9, it is limited and prevented from moving backward. This structure can provide the final positioning reference for the battery during the insertion process, ensuring that the battery forms a tight fit with the rear lock body 8, the guide clamping plate 6 and the guide rail 4, thereby achieving multiple limiting and fixing effects within the battery compartment as a whole.

[0042] Through the above design, the rear-insertion battery compartment guide sliding locking mechanism utilizes the guiding action of the guide clamping plate 6 during battery installation to enable the battery to be smoothly inserted into the track cavity 5. Furthermore, with the adaptive correction effect of the tapered guide surface, it eliminates the battery misalignment and jamming issues found in traditional insertion and removal structures.

[0043] After the battery is installed, the guide clamping plate 6, through the cooperation of the locking screw 12 and the knob block 7, applies a reliable clamping force to the battery, further preventing the battery from loosening during driving. At the same time, the rear lock body 8 inserts into the lock hole at the rear of the battery through the locking rod, forming a mechanical lock, fundamentally improving safety.

[0044] The entire structure is compact and reasonable, with the guiding and locking functions working together to achieve quick installation and stable fixation of the battery in the rear insertion and removal mode. This not only facilitates user operation but also ensures the safety and reliability of the vehicle during operation.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
