Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, specifically to a three-chamber frame tube that can accommodate batteries. Background Technology

[0002] With the rapid development of the electric bicycle and electric motorcycle industry, the design and manufacturing level of aluminum alloy frames, as a crucial structural component of the vehicle, directly impacts the overall performance and appearance. Currently, most aluminum alloy frame tubes on the market employ single-cavity or double-cavity structures, and traditional methods are generally used in battery box layout, lock seat assembly, decorative cover treatment, and battery box latch design. While these structures meet basic usage requirements to a certain extent, they have revealed numerous problems in practical applications, limiting product performance improvements and production efficiency optimization.

[0003] First, the single-chamber design, with the battery box sharing a single compartment, exposes the wiring harness, affecting the vehicle's aesthetics and safety. While the dual-chamber design provides wiring protection, it makes threading difficult and reduces production efficiency. Second, the existing top-removal and bottom-removal solutions are not interchangeable, leading to repeated mold making and increased R&D costs. Third, the split lock seat design is limited by frame space, making assembly difficult. Furthermore, the integrated structure of the battery box and decorative cover is complex and costly to manufacture, and different surface treatments result in inconsistent colors. Finally, if the battery box latch does not use metal gaskets and directly uses plastic materials with a metal latch, it is prone to wear over time, posing a safety hazard. These issues urgently need to be addressed through innovative structural design to improve overall vehicle performance and manufacturing efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a three-chamber frame tube that can accommodate batteries, in order to solve the problems of exposed wiring harnesses, incompatible removal methods, and easy wear of existing single-chamber tubes.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A three-cavity frame tube for battery installation is provided, comprising a frame tube with a hollow structure containing two independent cavities. The frame tube is open at both ends and has a slot at the bottom. A battery box is housed inside the frame tube, and a cover plate is provided between the frame tube and the battery box. A lock seat is located on the right side of the battery box inside the frame tube, and a vehicle lock is housed within the lock seat. The lock seat and the vehicle lock are integrally formed. A latch protection plate is provided at the connection between the battery box and the vehicle lock. Rotating the vehicle lock controls the locking or unlocking of the battery box. A push-down lock is located at the bottom of the battery box, and a push-down latch is located on the right side of the battery box. The push-down lock and the push-down latch are connected to further lock the battery box and the lock seat.

[0007] As a preferred embodiment of a three-chamber frame tube capable of housing batteries, a charging port is provided on the front side of the frame tube, and a sealing cap is provided on the outside of the charging port.

[0008] As a preferred embodiment of a three-chamber frame tube that can accommodate batteries, a charging port is provided on the front side of the battery box corresponding to the charging hole, a discharge seat is provided on the left side of the battery box, and a power display and a battery switch are respectively provided on the left side of the battery box.

[0009] As a preferred embodiment of a three-chamber frame tube that can accommodate batteries, the bottom of the battery box is provided with a battery box decorative cover, which is fitted into the strip groove.

[0010] In a preferred embodiment of a battery-equipped three-chamber frame tube, the battery switch is located above the power display.

[0011] The beneficial effects of this utility model are:

[0012] 1. The three-chamber frame tube structure not only improves the frame strength and processing stability, effectively reducing the risk of deformation and increasing the yield rate, but also enables the embedded arrangement of the wiring harness, enhancing protection performance and optimizing the overall wiring of the vehicle, improving assembly efficiency and product aesthetics. At the same time, the innovative design of the lock and fixing seat is integrated. Through the bottom-release push lock in conjunction with the vehicle lock, the battery box can be used for both "top-down" and "bottom-down" functions. This eliminates the need for repeated mold opening, significantly reducing R&D and production costs and improving adaptability and production efficiency.

[0013] 2. The separate battery box structure reduces the processing difficulty and cost. The battery box decorative cover can be processed separately on three axes and uniformly sprayed to ensure the consistency of the vehicle's appearance.

[0024] like Figure 1 and Figure 2As shown, this utility model provides a technical solution: a three-cavity frame tube for battery installation, including a frame tube 1. The frame tube 1 has a hollow structure, and two independent cavities are symmetrically arranged at the top of the hollow structure to enhance the overall strength of the frame tube 1, prevent deformation after processing, and improve the product yield. The right side of the frame tube 1 is the head tube end, and the left side is the bottom port end. Both ends of the frame tube 1 are open, and a strip groove is formed at its bottom. A battery box 2 is installed above the strip groove inside the frame tube 1. A cable cover plate 3 is installed between the frame tube 1 and the battery box 2. The cable cover plate 3 is located between the two independent cavities and is installed on the frame tube 1 with screws. The wiring harness can be directly laid inside the frame tube 1, and then the cable cover plate 3 covers the wiring groove, which can solve the problem of wiring harness protection, optimize the overall vehicle wiring, and improve production efficiency. A lock seat 4 is installed on the right side of the battery box 2 inside the frame tube 1. An internal lock 5 is installed to secure the battery box 2 inside the frame tube 1. The lock seat 4 is integrally formed with the lock 5. By directly fixing the lock seat 4 to the frame tube 1, a significant amount of labor installation costs are saved, improving production efficiency. A lock tongue protection plate 6 is installed on the right side of the battery box 2 cover where it connects to the lock 5. The lock tongue protection plate 6 is made of zinc alloy and is fixed to the cover of the battery box 2 with screws. This protects the cover of the battery box 2 from wear by the lock 5 during locking, increasing the service life of the battery box 2 and improving the stability of the lock 5. When needed, the wiring harness is arranged in sequence and placed on the top of the frame tube 1. Then, the cable cover plate 3 is installed inside the frame tube 1 to cover the wiring channel. The lock 5 is connected to the lock seat 4. The lock tongue protection plate 6 is then installed on the cover of the battery box 2. The battery box 2 is then installed on the lock seat 4 inside the frame tube 1. Rotating the lock 5 controls the locking or unlocking of the battery box 2.

[0025] like Figure 2 and Figure 3 As shown, a charging port 7 is provided on the front side of the frame tube 1. A sealing cover is movably installed on the outside of the charging port 7 to seal the charging port 7. A charging port 10 is installed on the front side of the battery box 2, corresponding to the charging port 7. A discharge seat 11 is installed on the left side of the battery box 2. A power display 12 and a battery switch 13 are installed on the left side of the battery box 2. The battery switch 13 is located above the power display 12. After the battery switch 13 is turned on, the power level of the battery box 2 can be displayed in real time through the power display 12. When charging is required, the sealing cover on the outside of the charging port 7 is opened, and an external power source is connected to the charging port 10 to charge the battery box 2. During driving, the battery box 2 is connected to the vehicle body through the discharge seat 11 to provide a power source.

[0026] like Figure 3As shown, a downward-release push-lock 8 is installed on the bottom right side of the battery box 2, and a downward-release lock tongue 9 is installed on the lower right side of the battery box 2 cover. The downward-release push-lock 8 and the downward-release lock tongue 9 are connected to further lock the battery box 2 and the lock seat 4. The downward-release push-lock 8, together with the vehicle lock 5, locks the battery box 2 vertically, so that the battery box 2 can be stably installed in the frame tube 1 whether it is installed upright or inverted. This realizes the universal function of "upward / downward release" of the battery box 2, eliminating the need for repeated mold opening, greatly reducing R&D and production costs, and improving adaptability and production efficiency. A battery box decorative cover 14 is installed at the bottom of the battery box 2. The battery box decorative cover 14 fits into the slot of the frame tube 1, and the battery box 2 can be directly cut, which reduces the processing difficulty, processing cost and processing time. At the same time, the battery box decorative cover 14 can be processed by a three-axis machine. Both the battery box decorative cover 14 and the whole vehicle can be painted to ensure the body color is consistent and improve the overall aesthetics. When it is necessary to remove it, turn the vehicle lock 5 to disengage the lock tongue protection plate 6 of the vehicle lock 5 from the battery box 2, thereby disengaging the lock seat 4 from the battery box 2. Then press the lower release lock 8 to disengage the lower release lock tongue 9 from the lock seat 4, and the battery box 2 can be removed from the frame tube 1.

[0027] Working principle: When needed, arrange the wiring harness in sequence and place it on top of the frame tube 1. Then, install the cover plate 3 inside the frame tube 1 to cover the wiring channel. Connect the lock 5 to the lock seat 4. Then, install the lock tongue protection plate 6 on the cover of the battery box 2. Then, snap the battery box decorative cover 14 onto the battery box 2. Finally, install the battery box 2 on the lock seat 4 inside the frame tube 1. After turning on the battery switch 13, the power level of the battery box 2 can be displayed in real time through the power display 12. When charging is required, open the sealing cover outside the charging port 7 and connect the external power source to the charging port 10 to charge the battery box 2. During driving, the battery box 2 is connected to the vehicle body through the discharge seat 11 to provide a power source. When the battery box 2 needs to be removed, turn the lock 5 to disengage the lock 5 from the lock tongue protection plate 6 of the battery box 2, thereby disengaging the lock seat 4 from the battery box 2. Then, press the lower release lock 8 to disengage the lower release lock tongue 9 from the lock seat 4, and the battery box 2 can be removed from the frame tube 1.
