Hydrogen fuel cell light bicycle hydrogen exchange safety locking mechanism

Abstract

This application discloses a hydrogen fuel cell lightweight bicycle hydrogen replacement safety locking mechanism, belonging to the technical field of hydrogen fuel cell lightweight bicycles. The locking mechanism includes relatively distributed rods and a triangular seat installed between the two rods. The triangular seat is located at the front end of the two rods. A secondary rod is fixedly connected to the end of each rod away from the triangular seat, and a handlebar is fixedly connected to the end of the secondary rod away from the rod. Side plates are fixedly installed on each rod. When a worker pushes the bicycle requiring battery replacement onto the device, the bicycle's front wheel bypasses the front side of the triangular seat, making contact with the rear side of the triangular seat. This prevents the bicycle from reversing due to slope, and the top of the front wheel contacts a pressing seat. The pressing seat, compressed by a spring, maintains the front wheel in a pressed position, thus ensuring stability during battery replacement and preventing tipping.

Description

Technical Field

[0001] This application relates to the field of hydrogen fuel cell light bicycle technology, specifically a hydrogen exchange safety locking mechanism for hydrogen fuel cell light bicycles. Background Technology

[0002] With the rapid development of the new energy transportation industry, hydrogen fuel cells have been widely used in the field of light bicycles due to their advantages such as zero pollution, long range, and fast refueling. Especially in the shared mobility scenario, hydrogen fuel cell light bicycles have become an important supplement to urban short-distance transportation due to their low maintenance costs and high efficiency. After the battery is depleted, these bicycles need to be replaced with hydrogen fuel cells on-site by staff to resume operation. The safety and efficiency of the hydrogen replacement operation directly affect the operating costs and service quality of shared bicycles.

[0003] To balance lightweight design and riding flexibility, existing hydrogen fuel cell light bicycles only have a rear wheel support leg for static parking at the rear, with no locking or positioning devices at the front. During hydrogen refueling, workers must open the battery compartment door on the bottom or side of the bicycle to remove the depleted hydrogen battery and install a new one. This process inevitably generates lateral thrust on the bicycle. Due to the light weight of the bicycle and the lack of fixed restraint at the front, this lateral thrust can easily cause the bicycle to tilt sideways around the rear wheel support leg, or even tip over completely. A tip over not only interrupts the hydrogen refueling process but may also damage the hydrogen battery casing, increasing the risk of battery leakage.

[0004] Therefore, this application provides a hydrogen swapping safety locking mechanism for hydrogen fuel cell light bicycles to solve the above problems. Utility Model Content

[0005] This application provides a hydrogen exchange safety locking mechanism for hydrogen fuel cell light bicycles, aiming to solve the problem mentioned in the background art that, due to the light weight of the light bicycle and the lack of fixed constraints at the front, lateral thrust can easily cause the bicycle to tilt sideways around the rear wheel support leg.

[0006] To achieve the above objectives, this application provides the following technical solution: a hydrogen exchange safety locking mechanism for a hydrogen fuel cell lightweight bicycle, comprising relatively distributed rods and a triangular seat installed between two rods. The triangular seat is located at the front end of the two rods. A secondary rod is fixedly connected to the end of each rod away from the triangular seat, and a handlebar is fixedly connected to the end of the secondary rod away from the rod. Side plates are fixedly installed on each rod, forming the basic frame of the locking mechanism and providing a structural carrier for subsequently locking the front wheel of the bicycle. At the same time, the handlebar enables convenient movement of the device.

[0007] Preferably, a bearing seat is fixedly installed on the side of the rod, and a wheel is installed on the bearing seat to improve the convenience and efficiency of hydrogen exchange operations.

[0008] Preferably, the triangular seat is triangular in shape, and the apex of the triangular seat is rounded to achieve initial positioning guidance for the front wheel of the bicycle, thereby improving the accuracy and safety of the locking operation.

[0009] Preferably, each of the auxiliary rods is provided with a positioning mechanism. The positioning mechanism includes a fixed ring fixedly sleeved on the auxiliary rod, a spring for sleeved with the auxiliary rod installed on the fixed ring, a movable ring connected to the end of the spring away from the fixed ring, the movable ring being movably sleeved with the auxiliary rod, and a pressing seat provided between the two movable rings to provide elastic adjustment capability for the pressing seat, adapting to different sizes of bicycle front wheels, and maintaining locking pressure.

[0010] Preferably, a fixing plate is fixedly installed on the side of the movable ring near the pressing seat, and a shaft groove is opened on the side of the fixing plate near the pressing seat. Shafts are fixedly installed on both sides of the pressing seat, and the shafts are movably connected to the corresponding shaft grooves. A threaded pin for positioning the shaft is threaded into the fixing plate.

[0011] Preferably, the pressing seat is U-shaped, and the inner edges of the pressing seat are all chamfered.

[0012] The locking mechanism allows staff to manually push the entire device to the vicinity of the bicycle parking area by holding the handlebar. The staff then pushes the bicycle that needs a battery swap onto the device, with the bicycle's front wheel bypassing the front of the triangular seat and contacting the rear of the triangular seat. This prevents the bicycle from rolling backward due to the slope, and the top of the front wheel contacts the pressing seat. The pressing seat, under the pressure of a spring, keeps the front wheel pressed and positioned, thus ensuring stability during battery replacement and preventing tipping.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] This embodiment provides a hydrogen swapping safety locking mechanism for lightweight hydrogen fuel cell vehicles, such as... Figure 1-3 As shown, the locking mechanism includes two rods 1 that are relatively distributed and a triangular seat 2 installed between the two rods 1. The triangular seat 2 is located at the front end of the two rods 1. A secondary rod 5 is fixedly connected to the end of the rod 1 away from the triangular seat 2. A handle rod 6 is fixedly connected to the end of the secondary rod 5 away from the rod 1. Side plates 3 are fixedly installed on each rod 1.

[0019] Specifically, the pole 1 serves as the main supporting frame, and the two poles 1 are connected at the front end through the triangular seat 2 to form a frame structure that can restrict the front wheel of the bicycle. The auxiliary pole 5 extends from the rear end of the pole 1, and the handle bar 6 is provided for the operator to hold to push and pull the equipment. The side plate 3 is fixed to the pole 1 to enhance the structural stability and provide auxiliary support.

[0020] A bearing seat is fixedly installed on the side of the rod 1, and a wheel 4 is installed on the bearing seat. The triangular seat 2 is triangular in shape, and a rounded chamfer is provided at the top corner of the triangular seat 2.

[0021] More specifically, the triangular seat 2 is triangular in shape. When the wheel 4 moves to the other side of the triangular seat 2, it can be prevented from reversing due to the slope. The wheel 4 is installed on the bearing seat on the side of the rod 1, so that the locking mechanism can roll on the ground through the wheel 4. The staff can easily push the equipment to the hydrogen exchange bicycle, improving the convenience and efficiency of the hydrogen exchange operation. When the triangular structure of the triangular seat 2 is close to the front wheel of the bicycle, it uses geometric guidance to accurately align the front wheel position. The rounded chamfer at the apex makes the edge smooth, avoiding scratching the bicycle or staff when in contact.

[0022] Each of the auxiliary rods 5 is provided with a positioning mechanism 7. The positioning mechanism 7 includes a fixed ring 71 fixedly sleeved on the auxiliary rod 5. A spring 72 for sleeved with the auxiliary rod 5 is installed on the fixed ring 71. A movable ring 73 is connected to the end of the spring 72 away from the fixed ring 71. The movable ring 73 is movably sleeved with the auxiliary rod 5. A pressing seat 74 is provided between the two movable rings 73.

[0023] Furthermore, the fixed ring 71 on the auxiliary rod 5 fixes one end of the spring 72, and the other end of the spring 72 is connected to the movable ring 73. The movable ring 73 can slide along the auxiliary rod 5. The pressing seat 74 between the two movable rings 73 is used to lock the bicycle front wheel. The elastic force of the spring 72 provides preload to the pressing seat 74, so that it can adapt to different front wheel sizes.

[0024] A fixing plate 731 is fixedly installed on the side of the movable ring 73 near the pressing seat 74. A shaft groove 732 is opened on the side of the fixing plate 731 near the pressing seat 74. A shaft 741 is fixedly installed on both sides of the pressing seat 74. The shaft 741 is movably connected to the corresponding shaft groove 732. A threaded pin 733 for positioning the shaft 741 is threaded into the fixing plate 731.

[0025] It should be noted that the fixing plate 731 on the movable ring 73 is movably connected to the shaft 741 of the pressing seat 74 through the shaft groove 732, so that the pressing seat 74 can rotate around the shaft 741. When the pressing seat 74 is inserted into the outer surface of the bicycle front wheel, the threaded pin 733 is tightened to fix the shaft 741 in the shaft groove 732, thereby realizing the positioning and locking of the pressing seat 74.

[0026] The pressing base 74 is U-shaped, and the inner edges of the pressing base 74 are all chamfered.

[0027] It is worth mentioning that the U-shaped structure of the pressing seat 74 can wrap around part of the bicycle's front wheel, improving locking stability; the chamfer on the inner edge makes the contact method "surface contact", reducing the pressure on the front wheel and avoiding damage.

[0028] In use, the staff manually supports the handlebar 6 to push the entire device to the vicinity of the bicycle parking area. The staff pushes the electric bicycle that needs a battery swap onto the device, and the front wheel of the bicycle goes around the front side of the triangular seat 2, so that the front wheel contacts the rear side of the triangular seat 2. It can be prevented from moving backward due to the influence of the slope, and the top of the front wheel will contact the pressing seat 74. The pressing seat 74 is pressed by the spring 72, which can keep the front wheel pressed and positioned. At this time, the staff can remove the battery from the bicycle and replace it. After the battery is replaced, the staff can drag the bicycle backward to detach it.

[0029] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
