Abstract

This utility model relates to the field of cargobike technology, specifically to a cargobike housing with support sensing and wire-controlled unlocking. This design utilizes a lever and cable mechanism on the steering handle to remotely control the retraction of the support structure, eliminating the need for the driver to frequently get on and off the vehicle, thus improving loading and unloading efficiency. This is especially beneficial in confined spaces or emergencies, avoiding the safety risks associated with getting off the vehicle to operate the support. Furthermore, a rotary limit switch detects the support rod's status. When the support rod is lowered, the vehicle's electronic control system automatically enters the P (Park) position, the motor stops working, and the driver is alerted via the display instrument. This effectively prevents the support components from scraping the ground, jamming, or even breaking, as well as safety accidents caused by vehicle imbalance.

Description

Technical Field

[0001] This utility model relates to the field of reverse-riding cargobike technology, and in particular to a cargobike housing with support sensing and wired unlocking. Background Technology

[0002] Currently, cargobikes, which are tricycles that ride backwards, are widely used in urban short-distance freight and community delivery scenarios due to their high flexibility and strong load-bearing capacity. Their core load-bearing component is the cargo box, which is usually installed at the rear or middle of the tricycle. The box relies on the frame for main support and can meet the needs of transporting goods over a certain distance and with a certain load capacity. This provides a convenient solution for urban logistics and distribution, and improves the efficiency and flexibility of goods transportation.

[0003] When loading and unloading goods, existing reverse-riding cargo bikes are prone to tilting if the center of gravity of the goods shifts, one side is overloaded, or the ground is slightly uneven. This can damage the goods and cause the vehicle to tip over. Some models are equipped with manual support structures to avoid this. In addition, the cargo boxes of existing reverse-riding cargo bikes on the market generally do not have supports, or the supports are mostly unlocked manually using mechanical unlocking methods.

[0004] However, firstly, the driver needs to get off the vehicle and manually pull the lever to put the support structure in the retracted state. This method is cumbersome and requires frequent getting on and off the vehicle, which reduces the efficiency of loading and unloading goods. Moreover, getting off the vehicle to operate in narrow spaces or in emergency situations poses safety hazards. Secondly, the driver is prone to riding with the support structure not retracted, which may cause the support components to scrape the ground, get stuck, or even break. It may also cause the vehicle to become unbalanced and cause a safety accident. Utility Model Content

[0005] The purpose of this invention is to provide a cargobike housing with support sensing and wire-controlled unlocking for a reversible tricycle. This addresses the technical problem in existing technology where the driver can manually retract the support by pulling a lever on the handlebars while seated, preventing the support from scraping the ground, getting stuck, or even breaking when it is not retracted, which could lead to vehicle imbalance and safety accidents. If the support is not retracted while the driver is riding, the support sensing device will send a signal to the instrument panel, which will then display the P (Park) gear status.

[0006] To achieve the above objectives, this utility model employs a cargobike box body with support sensing and wire-controlled unlocking, comprising a box body, a support rod, and a vehicle body. Front wheels are mounted on both sides of the box body. A fixing rod is located below the box body, and the fixing rod has two tension springs and two fixing blocks. One of the fixing blocks has a connecting rod, and both fixing blocks are located between the two tension springs. An L-shaped frame is located below the fixing rod, and a locking element is mounted on the L-shaped frame. The locking element is connected by a pull cable. Two locking plates are mounted on the support rod. One of the locking plates is equipped with a rotary limit switch. A rear wheel is located at one end of the vehicle body, a seat cushion is located in the middle of the vehicle body, and a steering handle is located at the other end of the vehicle body. The steering handle is equipped with a display instrument and two levers, and a pull cable is connected to one of the levers. The vehicle body is located on the steering handle. The support rod is rotatably mounted on two fixed blocks via two locking plates, and the pin end of the rotary limit switch is inserted into the connecting rod. The locking element is inserted into the other locking plate, and two tension springs are respectively connected to the two ends of the support rod.

[0007] The support rod has a first kick support at one end and a second kick support at the other end.

[0008] The support rod has a first support foot and a second support foot at its lower part, and the first support foot and the second support foot are symmetrically arranged.

[0009] The locking component includes a locking pin and a fixing cylinder. The fixing cylinder has a telescopic cavity, and a compression spring is provided in the telescopic cavity. The locking pin is slidably connected to the fixing cylinder and is located in the telescopic cavity, and also abuts against the compression spring. The pull wire is connected to the locking pin. The fixing cylinder is fixedly connected to the L-shaped frame and is located on the L-shaped frame. The locking pin is inserted into another locking piece.

[0010] The cargobike tricycle with support sensing and wired unlocking also includes a controller, which is mounted on the vehicle body, and the rotary limit switch is connected to the controller via a wire.

[0011] This utility model discloses a cargo box for a reverse-riding three-wheeled vehicle with support sensing and wire-controlled unlocking. The design utilizes a lever and cable mechanism on the steering handle to remotely control the retraction of the support structure, eliminating the need for the driver to frequently get on and off the vehicle, thus improving loading and unloading efficiency. Especially in confined spaces or emergencies, it avoids the safety risks of dismounting. The support can be automatically retracted while the driver is seated, effectively preventing the support components from scraping the ground, jamming, or even breaking, as well as safety accidents caused by vehicle imbalance. When parking, the driver needs to get off and kick the first and second support points to lower them. A rotary limit switch detects the support rod's status; when the support rod is lowered, the vehicle's electronic control system automatically enters the P (Park) position, the motor stops working, and the driver is alerted via the display instrument. This effectively prevents the support components from scraping the ground, jamming, or even breaking, as well as safety accidents caused by vehicle imbalance. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] Please see Figures 1 to 8 This utility model provides a cargobike box with support sensing and wired unlocking for a reversible tricycle, including a box body 1, a support rod 2, and a vehicle body 3. Front wheels 4 are provided on both sides of the box body 1. A fixing rod 5 is provided below the box body 1. Two tension springs 6 and two fixing blocks 7 are provided on the fixing rod 5. One of the fixing blocks 7 is provided with a connecting rod 8, and both fixing blocks 7 are located between the two tension springs 6. An L-shaped frame 9 is provided below the fixing rod 5, and a locking element is provided on the L-shaped frame 9. The locking element is connected by a pull cable 10. Two locking plates 11 are provided on the support rod 2, one of which... A rotary limit switch 12 is provided on the vehicle body 3. A rear wheel 13 is provided at one end of the vehicle body 3. A seat cushion 14 is provided in the middle of the vehicle body 3. A steering handle 15 is provided at the other end of the vehicle body 3. A display instrument 16 and two levers 17 are provided on the steering handle 15. The pull cable 10 is connected to one of the levers 17. The vehicle body 1 is provided on the steering handle 15. The support rod 2 is rotatably mounted on two fixed blocks 7 through two locking pieces 11. The pin end of the rotary limit switch 12 is inserted into the connecting rod 8. The locking piece is inserted into the other locking piece 11. Two tension springs 6 are respectively connected to the two ends of the support rod 2.

[0024] In this embodiment, the efficient and safe freight function is achieved through the design of the vehicle body 1, the support rod 2, the vehicle body 3, the support sensing structure, and the wire-controlled unlocking structure. This not only solves the problem of drivers having to frequently get off the vehicle to manually operate the support structure when loading and unloading goods in traditional reverse-riding cargo bikes, thus improving the efficiency of loading and unloading goods, but also prevents safety accidents caused by the driver riding with the support not retracted by automatically detecting the support status through the support sensing structure, significantly improving the safety and convenience of vehicle use.

[0025] Furthermore, a first kick support 18 is provided at one end of the support rod 2, and a second kick support 19 is provided at the other end of the support rod 2.

[0026] In this embodiment, when the support rod 2 needs to be lowered, the driver only needs to lightly kick the support at the corresponding position with his foot, and the support rod 2 will automatically fall and lock under the action of the tension spring 6, without the need to bend over or perform complicated operations.

[0027] Furthermore, a first support leg 20 and a second support leg 21 are provided below the support rod 2, and the first support leg 20 and the second support leg 21 are symmetrically arranged.

[0028] In this embodiment, when the support rod 2 is lowered, the two support legs evenly distribute the weight of the vehicle and cargo, reducing the risk of the container tilting due to the shift of the cargo's center of gravity or excessive weight on one side, thereby protecting the cargo from damage and reducing the possibility of the vehicle overturning.

[0029] Furthermore, the locking component includes a locking pin 22 and a fixing cylinder 23. The fixing cylinder 23 has a telescopic cavity 24, and a compression spring 25 is provided in the telescopic cavity 24. The locking pin 22 is slidably connected to the fixing cylinder 23 and is located in the telescopic cavity 24, and also abuts against the compression spring 25. The pull wire 10 is connected to the locking pin 22. The fixing cylinder 23 is fixedly connected to the L-shaped frame 9 and is located on the L-shaped frame 9. The locking pin 22 is inserted into another locking piece 11.

[0030] In this embodiment, when the driver moves the lever 17, the pull cable 10 pulls the locking pin 22 and the compression spring 25 and disengages from the locking piece 11 of the support rod 2, causing the support rod 2 to automatically retract under the action of the tension spring 6.

[0031] Furthermore, the cargobike box with support sensing and wire-controlled unlocking also includes a controller 26, which is mounted on the box body 1, and the rotary limit switch 12 is connected to the controller 26 via a wire.

[0032] In this embodiment, when the support rod 2 is lowered, the rotary limit switch 12 is triggered, sending a closing signal to the controller 26. The controller 26 then controls the motor to enter the P gear state and displays a parking reminder, effectively preventing safety accidents that may be caused by the driver riding with the support rod not retracted.

[0033] In this invention, when loading and unloading goods, if vehicle support is required, the driver can lightly kick the first kick support 18 or the second kick support 19 at one end of the support rod 2, causing the support rod 2 to fall and be relocked by the locking member. At this time, the first support foot 20 and the second support foot 21 symmetrically arranged below the support rod 2 stably contact the ground, enhancing vehicle stability. Simultaneously, the rotary limit switch 12 senses the fallen state of the support rod 2 and sends a signal to the controller 26. The controller 26 controls the motor to enter P gear and displays the position. The parking assist feature prevents the driver from accidentally riding while the support rod is in the extended position, ensuring safety and efficiency during use. When ready to ride, the support rod 2 is in the extended position, and the rider can ride on the bike without getting off. Simply rotate the specific lever 17 on the steering handlebar 15 and pull the cable 10 connected to the lever 17. This causes the locking pin 22 in the locking component to disengage from the locking piece 11 on the support rod 2, allowing the support rod 2 to automatically retract under the action of the built-in tension spring 6, and then riding can begin.

[0034] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
