Multifunctional portable electric bicycle for fishing

Abstract

This invention relates to the field of electric bicycle technology and discloses a multifunctional lightweight electric bicycle for fishing, including a front steering wheel, a frame, a power battery, a rear drive wheel, a saddle, a control handle, a front cargo basket, a mounting base, and a rear rack. This multifunctional lightweight electric bicycle for fishing allows for quick installation of the rear rack by inserting a rod at the bottom of the rear rack into a mounting box. The inclined surface of the rod's bottom matches the inclined surface of a locking block. During insertion, the inclined surface of the rod pushes the locking block outward against spring force. Once the rod is fully in place, the locking block automatically engages with a hole in the rod under the spring's return force, achieving quick installation of the rear rack. For disassembly, the user pulls the handle outward, causing the slider and locking block to move outward until the locking block disengages from the rod's hole, allowing the rear rack to be easily removed. This allows for quick assembly and disassembly of the rear rack, enabling rapid switching between cargo and passenger modes for outdoor fishing.

Description

Technical Field

[0001] This invention relates to the field of electric bicycle technology, specifically to a multifunctional lightweight electric bicycle for fishing. Background Technology

[0002] Electric bicycles are two-wheeled bicycles that use on-board batteries as auxiliary power and have the ability to be pedaled. They can achieve electric assistance or electric drive functions. They are essentially non-motorized vehicles. Their maximum design speed shall not exceed 25 kilometers per hour. Key parameters such as the overall vehicle weight, motor power, and nominal battery voltage are all subject to clear limits. They are strictly distinguished from motorized vehicles such as electric motorcycles in terms of legal attributes and technical indicators.

[0003] Existing electric bicycles, when used for carrying cargo in outdoor fishing or other scenarios, generally have short wheelbases and insufficient distance between the saddle and the rear wheel center, resulting in extremely limited rear physical space. Commonly used standard fishing gear cannot be loaded, or the loaded cargo exceeds the length and height limits of the vehicle, violating road traffic safety regulations. At the same time, existing models lack quick-assembly and disassembly mechanisms. When users switch between different scenarios such as passenger commuting, cargo transportation, and fishing transportation, changing the rear rack and rear seat requires tools and is time-consuming, failing to achieve flexible functional conversion. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional, lightweight electric bicycle for fishing, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multi-functional lightweight electric bicycle for fishing, including a front steering wheel, a frame, a power battery, a rear drive wheel, a saddle, a control handle, a front cargo basket, a mounting base, and a rear clothes rack, wherein the mounting base is provided with a quick-release assembly, and the frame is provided with a folding assembly; The quick-release assembly includes a rear shelf, with cable ties fixedly connected to the bottom of the rear shelf, an installation box fixedly connected to the bottom of the mounting base, a slider slidably connected inside the installation box, a handle fixedly connected to the outside of the slider, a spring fixedly connected between the slider and the inner wall of the installation box, a locking block fixedly connected to the side of the slider away from the handle, and an insertion rod fixedly connected to the bottom of the rear shelf.

[0006] Preferably, the front steering wheel is rotatably connected to the front side of the vehicle body, the rear drive wheel is rotatably connected to the rear side of the vehicle body, and the power battery supplies power to the rear drive wheel.

[0007] Preferably, the saddle is fixedly connected to the top of the vehicle body, the control handle is fixedly connected to the top of the vehicle body, and the front cargo basket is inserted into the outside of the control handle.

[0008] Preferably, the mounting base is fixedly connected to the outside of the vehicle body and located above the rear drive wheel, and the rear clothes rack includes a rear seat cushion and a backrest, with the rear seat cushion inserted into the mounting base via a positioning rod.

[0009] Preferably, the mounting box is fixedly connected to the bottom of the mounting base, and the number of the insertion rods is four and they are centrally symmetrically distributed at the bottom of the rear shelf, with the mounting box and the insertion rods corresponding one-to-one.

[0010] Preferably, the insertion rod passes through the mounting base and engages with the inner bottom wall of the mounting box. The bottom surface of the insertion rod is designed with an angle, and the side of the locking block away from the handle is also designed with an angle and is adapted to the insertion rod. The insertion rod has a through hole adapted to the locking block.

[0011] Preferably, the upper and lower sides of the slider are fixedly connected to limit blocks, the upper and lower sides of the inner wall of the mounting box are provided with limit grooves that are adapted to the movement trajectory of the limit blocks, the handle extends to the outside of the mounting box, and the spring is sleeved on the outside of the handle.

[0012] Preferably, the folding assembly includes a connecting seat, a connecting block is rotatably connected to the inner side of the connecting seat, and a vertical rod is inserted into the top of the connecting seat.

[0013] Preferably, the vehicle body is divided into left and right sides, the connecting seat is fixedly connected to the left side of the vehicle body, the connecting block is fixedly connected to the right side of the vehicle body, the vertical rod passes through the connecting block and is engaged with the connecting seat, and the vertical rod is fixed to the connecting seat by bolts.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention inserts a rod at the bottom of the rear shelf into the mounting box through the mounting base. The inclined surface at the bottom of the rod matches the inclined surface of the locking block on the side away from the handle. During the insertion process, the inclined surface of the rod pushes the locking block to slide outward against the spring force. After the rod is fully in place, the locking block automatically locks into the through hole on the rod under the action of the spring rebound force, achieving quick installation with one-click locking. When disassembly is required, the user only needs to pull the handle outward. The handle drives the slider and locking block to move outward against the spring force until the locking block disengages from the through hole of the rod, and the rear shelf can be easily removed upward. The user can quickly complete the disassembly and assembly of the rear shelf without the need for any tools, realizing a quick switch between outdoor fishing cargo mode and passenger mode, and greatly improving the conversion efficiency of the vehicle in different usage scenarios.

[0015] Secondly, this invention fixes the connecting seat to the left side of the vehicle body and the connecting block to the right side of the vehicle body, with the connecting block rotatably connected to the inside of the connecting seat. The vertical rod passes through the connecting block and is inserted into the top of the connecting seat, and is locked and fixed to the connecting seat with bolts. This rigidly locks the left and right sides of the vehicle body into a straight state. When the user needs to fold and store the vehicle, they only need to loosen the bolts and pull the vertical rod upwards to release the axial lock between the connecting block and the connecting seat. At this time, the left and right sides of the vehicle body can be folded in half through the rotational cooperation of the connecting block and the connecting seat, achieving the effect of quick folding and storage of the vehicle.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides the following technical solutions: Example 1

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 10 A multi-functional lightweight electric bicycle for fishing includes a front steering wheel 1, a frame 2, a power battery 3, a rear drive wheel 4, a saddle 5, a control handle 6, a front cargo basket 7, a mounting base 8, and a rear clothes rack 9. The mounting base 8 is equipped with a quick-release assembly, and the frame 2 is equipped with a folding assembly. The quick-release assembly includes a rear shelf 10, with cable ties 11 fixedly connected to the bottom of the rear shelf 10. A mounting box 12 is fixedly connected to the bottom of the mounting base 8. A slider 13 is slidably connected inside the mounting box 12. A handle 14 is fixedly connected to the outside of the slider 13. A spring 15 is fixedly connected between the slider 13 and the inner wall of the mounting box 12. A locking block 16 is fixedly connected to the side of the slider 13 away from the handle 14. A plug bar 17 is fixedly connected to the bottom of the rear shelf 10.

[0021] The front steering wheel 1 is rotatably connected to the front side of the vehicle body 2, and the rear drive wheel 4 is rotatably connected to the rear side of the vehicle body 2. The power battery 3 supplies power to the rear drive wheel 4.

[0022] By rotating the front steering wheel 1 to the front of the vehicle body 2 and rotating the rear drive wheel 4 to the rear of the vehicle body 2, and allowing the power battery 3 to supply power to the rear drive wheel 4, stable power output for rear-wheel drive is achieved, ensuring smooth driving.

[0023] The saddle 5 is fixedly connected to the top of the vehicle body 2, the control handle 6 is fixedly connected to the top of the vehicle body 2, and the front cargo basket 7 is inserted into the outside of the control handle 6.

[0024] By fixing the saddle 5 and the control handle 6 to the top of the vehicle body 2, and installing the front cargo basket 7 on the outside of the control handle 6 by plugging it in, the ergonomics of the driving position is optimized. At the same time, the plug-in quick-install structure of the front cargo basket 7 allows the driver to quickly install and remove the cargo basket without tools, which is convenient for daily shopping or carrying personal items and improves the convenience of daily commuting.

[0025] Mounting bracket 8 is fixedly connected to the outside of vehicle body 2 and located above the rear drive wheel 4. The rear rack 9 includes a rear seat cushion and a backrest. The rear seat cushion is inserted into mounting bracket 8 via a positioning rod.

[0026] By fixing the mounting base 8 to the outside of the vehicle body 2 and above the rear drive wheel 4, and inserting the rear seat cushion of the rear rack 9 into the mounting base 8 through the positioning rod, the function of carrying passengers and carrying cargo for outdoor fishing can be quickly switched. When the rear rack 9 is inserted, it becomes the passenger mode, and when it is replaced with the rear rack 10, it becomes the cargo mode. The function can be switched without any tools. Moreover, the layout of the rear seat cushion above the rear drive wheel 4 effectively utilizes the longitudinal space above the rear drive wheel 4, ensuring the stability and comfort of the rear seat when carrying passengers.

[0027] The mounting box 12 is fixedly connected to the bottom of the mounting base 8. There are four insertion rods 17, which are centrally symmetrically distributed at the bottom of the rear shelf 10. The mounting box 12 and the insertion rods 17 are set one-to-one.

[0028] The rear rack 10 achieves balanced force support at four points, improving its load-bearing stability and torsional resistance. Even when loaded with heavy items such as standard fishing boxes or standard live fish buckets, it ensures that the goods do not shake during vehicle operation, thus guaranteeing driving safety.

[0029] The insertion rod 17 passes through the mounting base 8 and engages with the inner bottom wall of the mounting box 12. The bottom surface of the insertion rod 17 is designed with a slope. The side of the locking block 16 away from the handle 14 is also designed with a slope and is adapted to the insertion rod 17. The insertion rod 17 has a through hole adapted to the locking block 16.

[0030] The automatic locking function of the rear rack 10 is realized. When the insertion rod 17 is inserted, the inclined surface cooperates to make the locking block 16 automatically move out of place, and automatically springs back into the hole after it is in place. The whole process does not require manual operation of the locking buckle, realizing a quick installation experience of one-plug-and-lock, which greatly improves the convenience of users to assemble and disassemble the rack.

[0031] Limit blocks are fixedly connected to both the upper and lower sides of the slider 13. Limit grooves that match the movement trajectory of the limit blocks are opened on both the upper and lower sides of the inner wall of the mounting box 12. The handle 14 extends to the outside of the mounting box 12, and the spring 15 is sleeved on the outside of the handle 14.

[0032] By setting limit blocks on the upper and lower sides of the slider 13 and opening limit grooves on the upper and lower sides of the inner wall of the mounting box 12 to match the movement trajectory of the limit blocks, it is ensured that the slider 13 can only slide in a straight line in the horizontal direction in the mounting box 12 without deviating or getting stuck. At the same time, the handle 14 extends to the outside of the mounting box 12 to facilitate the user's grip and operation. The spring 15 is sleeved on the outside of the handle 14, which saves space and protects the spring 15 from interference from external debris.

[0033] Please see Figure 11 A multi-functional lightweight electric bicycle for fishing can load fishing rods and fishing umbrellas via cable ties 11 at the bottom of the rear rack 10. A standard fishing platform can be placed on top of the rear rack 10, and a standard fishing box and a standard live fish bucket can be placed on top of the standard fishing platform, thus enabling the loading of standard fishing gear commonly used for outdoor fishing. Example 2

[0034] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 11 A multi-functional lightweight electric bicycle for fishing, the folding assembly includes a connecting seat 18, a connecting block 19 rotatably connected to the inner side of the connecting seat 18, and a vertical rod 20 inserted into the top of the connecting seat 18.

[0035] When the vertical rod 20 is pulled out, the connecting block 19 can rotate freely to achieve the folding of the vehicle body 2. When the vertical rod 20 is inserted, it is rigidly locked to keep the vehicle body 2 straight. After folding, the length of the vehicle is greatly shortened, and it can be easily put into the trunk of a car.

[0036] The vehicle body 2 is divided into left and right sides. The connecting seat 18 is fixedly connected to the left side of the vehicle body 2, and the connecting block 19 is fixedly connected to the right side of the vehicle body 2. The vertical rod 20 passes through the connecting block 19 and is snapped into the connecting seat 18. The vertical rod 20 is fixed to the connecting seat 18 by bolts.

[0037] The vertical rod 20 provides axial locking to prevent the connecting block 19 from rotating accidentally, and the bolt provides radial locking to prevent the vertical rod 20 from loosening. This double protection ensures the absolute rigidity of the folding mechanism during vehicle operation and prevents the vehicle body 2 from loosening during normal driving. Example 3

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 11 A multi-functional, lightweight electric bicycle for fishing is designed with a wheelbase of 1250mm or less and 1000mm or more, and the distance between the saddle 5 and the center of the rear drive wheel 4 is greater than or equal to 50% of the wheelbase. Therefore, the distance between the saddle 5 and the center of the rear drive wheel 4 is large enough, allowing for the compliant loading of fishing gear and doubling the number of power batteries 3 to double the range.

[0039] When in use, for transportation during outdoor fishing, the user can insert the front basket 7 into the control handle 6, then pass the insertion rod 17 at the bottom of the rear rack 10 through the mounting base 8 and insert it into the mounting box 12. The inclined surface at the bottom of the insertion rod 17 will push the locking block 16 to slide outward against the elastic force of the spring 15. After the insertion rod 17 is in place, the locking block 16 will automatically lock into the through hole of the insertion rod 17 under the action of the spring 15, achieving quick locking. The front basket 7, the rear rack 10, and the cable ties 11 at the bottom of the rear rack 10 can be used to load standard fishing boxes, standard live fish buckets, and standard fishing platforms. When switching to passenger mode, the rear seat cushion of the rear rack 9 can be inserted into the mounting base 8 through the positioning rod. When storing the vehicle, remove the bolts on the vertical rod 20 and pull out the vertical rod 20 to unlock the connecting block 19 from the connecting base 18, allowing the vehicle body 2 to be folded in half on both sides for quick folding.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
