Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing technology, and in particular to a wheel hub storage device for electric bicycles. Background Technology

[0002] The wheel hub of an electric bicycle is a core component of the vehicle's power system. It is usually made of high-strength metal materials and integrates a motor and transmission structure. Its compact design ensures efficient energy conversion, while the external spokes support the tire to form a whole, combining load-bearing and driving functions. With the increasing demand for short-distance urban travel, the frequency of wheel hub use has increased significantly. To address the maintenance needs after frequent use, a dedicated storage device has emerged. This device adopts a modular frame structure, which effectively reduces the wear and tear on precision components caused by environmental factors and extends the service life of the equipment.

[0003] Traditional electric bicycle wheel hub storage devices mainly achieve vertical placement of the wheel hub by combining a fixed support rod with a base. The principle is to use the clamping component at the top of the support rod to fix the wheel hub axle, and the base distributes the overall weight of the wheel hub by gravity, thereby achieving static storage. This type of device has a simple structure and low cost, but because the height of the support rod is fixed, it can only be used for wheel hubs of specific sizes, which limits its application scenarios.

[0004] Existing electric bicycle wheel hub storage devices improve the flexibility of clamping components by employing rotatable buckles and multi-directional adjustable bases. They also enhance wheel hub placement stability through added damping structures and optimize the anti-rust coating process parameters to extend device lifespan. However, in practical use, these devices cannot adjust the support rod height according to wheel hub specifications. The lack of a height adjustment mechanism results in insufficient adaptability to wheel hubs of different diameters, requiring users to frequently replace parts or adjust the installation angle. This not only reduces operational efficiency but also causes wear on the wheel hub surface or deformation of the support rod due to matching errors, further increasing maintenance costs. Therefore, an electric bicycle wheel hub storage device is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electric bicycle wheel hub storage device, which aims to improve the problem that the existing device is not adaptable to wheel hubs of different diameters. Users need to frequently replace parts or adjust the installation angle, which not only reduces the operating efficiency, but also causes wear on the wheel hub surface or deformation of the support rod due to matching errors, further increasing the maintenance cost.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electric bicycle wheel hub storage device, comprising a support platform and a base, an outer column fixedly connected to the top of the outer wall of the base, a spring-loaded mechanism provided on the inner wall of the outer column, a limiting mechanism fixedly connected to the bottom of the outer wall of the support platform, an inner column fixedly connected to the inner wall of the outer column, a fixing mechanism provided on the outer wall of the inner column, the fixing mechanism including threads, a threaded connection fixedly connected to the outer wall of the outer column, a threaded cavity opened on the inner wall of the inner column, a rotating mechanism provided on the outer wall of the inner column, and a durable mechanism provided on the inner wall of the outer column;

[0008] Preferably, the limiting mechanism includes a push plate, the front side of the outer wall of the push plate is fixedly connected to the rear side of the outer wall of the support platform, a plurality of partitions are fixedly connected to the front side of the outer wall of the push plate, a slide plate is fixedly connected to the front side of the outer wall of the push plate, a plurality of pulleys are fixedly connected to the bottom of the outer wall of the slide plate, and a handle is fixedly connected to the rear side of the outer wall of the push plate.

[0009] Preferably, the fixing mechanism includes threads, the outer wall of the outer column is fixedly connected with threads, and the inner wall of the inner column has a threaded cavity.

[0010] Preferably, the rotating mechanism includes a rotating block, the outer wall of which is rotatably connected to the inner wall of the inner column, and the outer wall of the inner column has a rotating cavity.

[0011] Preferably, the durable mechanism includes a wear-resistant layer, the outer wall of which is fixedly connected to the inner wall of the outer column, and a sound-absorbing layer is fixedly connected to the inner wall of the wear-resistant layer.

[0012] Preferably, the outer wall of the support platform is fixedly connected with a connecting bar, and the top of the outer wall of the connecting bar is fixedly connected to the bottom of the outer wall of the base.

[0013] Preferably, a weight-reducing strip is fixedly connected to the outer wall of the support platform, and multiple alloy columns are fixedly connected to the bottom of the outer wall of the support platform.

[0014] Preferably, a hub is fixedly connected to the top of the outer wall of the base, and the inner diameter of the hub is larger than the outer diameter of the outer column.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when it is necessary to adjust the height of the support rod, simply rotate the knob on the top of the inner column counterclockwise. This knob has a built-in rotating cavity and rotating block, which can realize the separation operation of the inner column and the outer column while the inner column is stationary. When the knob is turned on, the inner column and the outer column are separated by the internal spring, causing the inner column to spring upward and stop moving under the restriction of the buffer pad and the limiting piece, thus completing the adjustment of the height of the support rod.

[0017] 2. In this utility model, the partition plate is embedded between the fixed wheel hubs on the support column by the handle behind the push plate, ensuring the relative stability between the wheel hubs. When it is necessary to remove the wheel hub for processing, it is only necessary to pull the handle to separate the partition plate from the wheel hub. This structure achieves the function of fixing the wheel hubs and avoids damage caused by collision between the wheel hubs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 4 , Figure 5 and Figure 6 This utility model provides an embodiment of an electric bicycle hub storage device, comprising a support platform 1 and a base 2. An outer column 3 is fixedly connected to the top of the outer wall of the base 2, serving as the outer shell of a support rod, providing structural support and guiding the sliding direction of an inner column 4. The inner column 4 is a telescopic core structure that transmits external force and cooperates with elastic components to achieve elastic movement. A rebound mechanism 5 is provided on the inner wall of the outer column 3. A limit mechanism 6 is fixedly connected to the bottom of the outer wall of the support platform 1. An inner column 4 is fixedly connected to the inner wall of the outer column 3. A fixing mechanism 7 is provided on the outer wall of the inner column 4, including a thread 701. The outer wall of the outer column 3 is fixedly connected with the thread 701, and the inner wall of the inner column 4 has a threaded cavity 702. The outer wall of the inner column 4 is provided with a rotating mechanism 8, which includes a rotating block 802. The rotating block 802 and the rotating cavity 801 cooperate with each other to keep the inner rod stationary while the thread 701 and the thread cavity 702 rotate. The outer wall of the rotating block 802 is rotatably connected to the inner wall of the inner column 4. The outer wall of the inner column 4 has a rotating cavity 801. The inner wall of the outer column 3 is provided with a durable mechanism 9, which includes a wear-resistant layer 901, which reduces the frictional wear between the inner column and the inner wall of the outer column 3 and extends the service life. The outer wall of the wear-resistant layer 901 is fixedly connected to the inner wall of the outer column 3. The inner wall of the wear-resistant layer 901 is fixedly connected to a sound-absorbing layer 902, which reduces the noise generated when the inner column slides and improves the comfort of use.

[0029] The rebound mechanism 5 includes a fixed seat 501, which fixes the bottom position of the spring 502 to ensure that the spring 502 is stably compressed or extended. The bottom of the outer wall of the fixed seat 501 is fixedly connected to the bottom of the inner wall of the outer column 3. The top of the outer wall of the fixed seat 501 is fixedly connected to the spring 502, which stores and releases energy and provides elastic restoring force to buffer impact or vibration. The top of the outer wall of the spring 502 is fixedly connected to a limiting piece 503, which limits the stroke range of the inner column 4 to prevent damage caused by excessive compression or stretching. The inner wall of the outer column 3 is fixedly connected to a buffer pad 504, which absorbs collision energy at the contact point between the outer column 3 and the inner column 4 to reduce hard impact.

[0030] Specifically, the top of the outer wall of the base 2 is fixedly connected to the outer column 3, which serves as the outer shell of the support rod. This structure provides rigid support for the overall frame and guides the inner column 4 to slide along the axis through an internal smooth channel. The inner column 4, as a retractable core structure, transmits force through vertical displacement when subjected to external loads and works in conjunction with the built-in elastic components to perform a buffering function. The inner wall area of ​​the outer column 3 is equipped with a rebound mechanism 5. The bottom of the outer wall of the support platform 1 is connected to a limit mechanism 6 by welding. This mechanism forms a spatial fit with the inner column 4. The inner wall of the outer column 3 is connected by a mechanism... The inner column 4 is fixed by a mechanical buckle. A fixing mechanism 7 is distributed on the outer wall surface of the inner column 4. This mechanism consists of fastening components with threads 701. The outer wall of the outer column 3 is precision-machined to form threads 701 that match the threaded cavity 702. The inner wall of the inner column 4 is provided with a threaded cavity 702 that rotatably engages with the thread 701. The rotating mechanism 8, through the cooperation of a rotating block 802 and the rotating cavity 801, ensures that the inner column 4 remains stationary when the thread 701 and the threaded cavity 702 rotate relative to each other. The rotating block 802 is rotatably connected to the inner wall of the inner column 4 through a bearing assembly. The outer wall of the inner column 4 has a rotating cavity 801 for the rotating block 802 to be embedded. The inner wall surface of the outer column 3 is covered with a durable mechanism 9 made of multi-layer composite material. Its wear-resistant layer 901 is fixed to the inner wall surface of the outer column 3 by a hot-melt process, which effectively reduces the friction coefficient when the inner column 4 slides. The sound-absorbing layer 902 is bonded to the wear-resistant layer 901 by an adhesive, which uses the sound absorption properties of polymer materials to suppress the sound wave vibration generated by mechanical movement. The core component fixing seat 501 of the rebound mechanism 5 is fixed to the bottom of the inner wall of the outer column 3 by bolts. This base 2 provides the spring 502 with A stable support platform is provided. The top of the spring 502 is rigidly connected to the limiting plate 503. The spring absorbs kinetic energy and converts it into potential energy through elastic deformation. The limiting plate 503 and the reserved groove on the inner wall of the outer column 3 form a physical limit, which precisely controls the maximum extension stroke of the inner column 4. An annular buffer pad 504 is provided at the edge of the inner wall of the outer column 3. This component is made of highly elastic polyurethane material. When the support platform 1 and the base 2 undergo violent relative movement, the material deformation absorbs the impact energy at the moment of contact between the inner column 4 and the outer column 3, thereby protecting the mechanical structure from damage caused by rigid collision.

[0031] Reference Figure 1 , Figure 2 and Figure 7 The limiting mechanism 6 includes a push plate 601. The front side of the outer wall of the push plate 601 is fixedly connected to the rear side of the outer wall of the support platform 1. Multiple partitions 602 are fixedly connected to the front side of the outer wall of the push plate 601. The partitions 602 are used to separate the hubs 12 from each other to avoid collision damage. A slide plate 603 is fixedly connected to the front side of the outer wall of the push plate 601. Multiple pulleys 604 are fixedly connected to the bottom of the outer wall of the slide plate 603. A handle 605 is fixedly connected to the rear side of the outer wall of the push plate 601. The slide plate 603, pulleys 604 and handle 605 interact to control the removal and placement of the partitions 602.

[0032] Specifically, the limiting mechanism 6 is composed of a push plate 601. The front outer wall of the push plate 601 is rigidly connected to the rear outer wall of the support platform 1 by welding. Multiple partitions 602 are vertically fixedly installed on its front surface. The partitions 602 are arranged in parallel to separate adjacent hub bodies 12 into independent spaces to avoid surface damage caused by contact during the movement of the hub bodies 12. The front outer wall of the push plate 601 is also fixedly installed with a sliding plate 603. The bottom outer wall of the sliding plate 603 is connected with multiple pulleys 604 by riveting. The pulleys 604 roll along a preset track to reduce frictional resistance. A handle 605 is installed on the rear outer wall of the push plate 601. The sliding plate 603 achieves horizontal displacement through the rolling of the pulleys 604. The handle 605 provides a human traction fulcrum. The three work together to complete the extraction or resetting operation of the partitions 602, ensuring the convenience and safety of the storage and retrieval process of the hub bodies 12.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A connecting bar 10 is fixedly connected to the outer wall of the support platform 1 for placing the support rod. The top of the outer wall of the connecting bar 10 is fixedly connected to the bottom of the outer wall of the base 2. A weight-reducing bar 11 is fixedly connected to the outer wall of the support platform 1 for dispersing the force borne by the support platform 1. Multiple alloy columns 13 are fixedly connected to the bottom of the outer wall of the support platform 1 for supporting the support platform 1. A hub 12 is fixedly connected to the top of the outer wall of the base 2 for supporting the tire and connecting the axle to transmit driving force to drive the electric vehicle. The inner diameter of the hub 12 is larger than the outer diameter of the outer column 3.

[0034] Specifically, the outer wall of the support platform 1 is rigidly connected to the connecting bar 10, which is used to support the positioning function of the support rod. Its top outer wall is fixed to the bottom outer wall of the base 2 by bolts. Weight-reducing strips 11 are distributed on the surface of the outer wall of the support platform 1. This structure evenly distributes the vertical load borne by the support platform 1 through the horizontal extension design. Several alloy columns 13 are vertically fixed on the bottom outer wall of the support platform 1. The alloy columns 13 provide basic support for the support platform 1 through high-strength metal material. The top outer wall of the base 2 is connected to the hub 12 through a flange. The hub 12 is the core carrier of the drive system. It is linked with the axle through bearings and transmits power to the tires to drive the electric vehicle to travel smoothly. The inner diameter of the hub 12 is precision machined to form an annular channel. Its diameter is designed to be slightly larger than the outer diameter of the outer column 3 to ensure that a reasonable assembly gap is maintained between the outer column 3 and the hub 12.

[0035] Working principle: First, when the height of the support rod needs to be adjusted, rotate the knob 4 on the top of the inner column counterclockwise. The knob 4 integrates a rotating cavity 801 and a rotating block 802. Through the meshing action of the rotating block 802 and the rotating cavity 801, the inner column 4 is kept stationary and the locking relationship between the thread 701 and the threaded cavity 702 of the outer column 3 is released. After the knob 4 is rotated, the spring 502 at the bottom of the inner wall of the outer column 3 generates a rebound force due to the release of elastic potential energy, which pushes the inner column 4 to extend upward along the axis of the outer column 3. When the inner column 4 moves to the preset height, the limiting piece 503 on the top of the fixed seat 501 and the buffer pad 504 on the inner wall of the outer column 3 together form a physical limit, which absorbs kinetic energy to suppress the inner column 4 from continuing to move, and finally realizes the adjustment and locking of the height of the support rod.

[0036] Furthermore, by operating the handle 605 on the rear side of the push plate 601, the partition 602 is precisely embedded into the pre-set gap of the hub 12 on the support platform 1. The vertical separation effect of the partition 602 maintains the relative positional stability of adjacent hubs 12. When the hub 12 needs to be disassembled for work, force is applied to the handle 605 to drive the slide plate 603 to move laterally. The pulley 604 at the bottom of the slide plate 603 slides along the track to generate displacement, simultaneously pulling the partition 602 away from the assembly area of ​​the hub 12. This linkage structure realizes the function of quickly picking up and putting down the hub 12 through mechanical separation action. The physical isolation characteristics of the partition 602 effectively prevent the surface of the hub 12 from being scratched or deformed due to accidental contact. The rolling mechanism of the pulley 604 significantly reduces the operating resistance. The ergonomic design of the handle 605 ensures the convenience of the operator in the process of applying force. The whole device takes into account both protective performance and operating efficiency, and provides reliable protection for the storage and maintenance of the hub 12.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
