Description

Technical Field

[0001] The invention relates to a transport vehicle, in particular to a light-duty urban distribution vehicle. Background Art

[0002] At present, my country's same-city delivery industry is developing rapidly and is currently ahead of other countries and regions in the world; there are a huge number of same-city delivery riders. For example, the number of Meituan riders registered in China has exceeded 6 million. Electric vehicles, especially two-wheeled electric vehicles, have become an important means of transportation for same-city delivery riders due to their lightness, flexibility, low purchase and maintenance costs, etc. Since the average daily riding time of same-city delivery riders is more than 10 hours, the riding time is long, so the demand for safety and comfort of electric delivery vehicles is relatively high. At the same time, due to the distribution needs, there are also high requirements for the carrying and storage functions of electric delivery vehicles.

[0003] Most existing electric delivery vehicles adopt an open body structure, which is light and flexible. However, the open structure also makes the electric delivery vehicles less comfortable, especially in low temperature, dust, haze, rain and snow weather. The open structure of the electric delivery vehicle cannot provide shelter from wind and rain, dust and heat preservation, and the comfort is greatly reduced. In addition, with the frequent occurrence of large-scale infection incidents of epidemic viruses in recent years, enclosed riding space has become a new demand for electric delivery vehicles. The enclosed private space can not only ensure personal safety, but also enhance psychological security. In addition, the following factors that affect the safety of existing electric delivery vehicles are also present in the use of the following: because the body structure of the electric delivery vehicle is open, it cannot effectively provide timely protection for the driver during a collision; most electric delivery vehicles are two-wheeled, and the body cannot always maintain a balanced state when turning on slippery roads or during a collision and sharp turning; the effective visual range of the rearview mirror of the electric delivery vehicle is limited, and the driver cannot grasp the rear traffic conditions in real time and comprehensively, so as to make predictions and avoidance in time; the seat design of the electric delivery vehicle generally tends to carry two adults, so the existing seat structure cannot provide good protection when carrying children; the driver of the electric delivery vehicle will look at the mobile phone, reply to messages, drink water, etc. during driving, which will cause the driver's line of sight to deviate from the driving route and distract attention, etc. The existence of the above safety factors, coupled with the indifference of safety awareness of some electric delivery vehicle drivers, has led to frequent traffic accidents related to electric delivery vehicles, which not only harms the drivers of electric delivery vehicles, but also endangers the lives of pedestrians and the safety of others and public property.

[0004] At the same time, the existing electric delivery vehicles mostly use delivery boxes installed at the back seat of the vehicle for carrying and storing. The delivery personnel stack multiple delivery items in bags or boxes in the delivery boxes. During the delivery journey, the delivery items in the delivery boxes may overturn due to bumps or unstable driving of the electric delivery vehicle, causing chaos. In particular, the delivery items containing liquids such as soup will overflow, which will not only cause pollution, but also cause disputes such as user complaints. In addition, since the same-city delivery business is generally a one-time selection of delivery merchants by delivery users and the delivery tasks are randomly assigned to delivery personnel by the system, the trust between delivery merchants and delivery personnel, delivery personnel and delivery users, and delivery users and delivery merchants is generally fragile. Any unexpected event during the delivery task may undermine the trust between each other, thereby causing delivery business disputes.

[0005] Therefore, an electric delivery vehicle that can meet the requirements of safety, comfort, carrying and storage, and minimize delivery business disputes is urgently needed by the majority of delivery riders. Summary of the invention

The warning display device 11 can adopt an LED light group display arranged at the top center position of the outer side of the rear wall of the cab 6. The LED light group display can display information such as left turn, right turn and braking, so that the driver's steering intention and start-stop intention are more eye-catching, and the rear vehicles or pedestrians are reminded in time to improve the safety of the traffic environment; and the LED light group display can emit fluorescence at night, so that the rear vehicles or pedestrians can clearly understand the specific location of the delivery vehicle, which plays a role in reminding and warning the rear vehicles.A gyroscope 15 is provided in the vehicle body 1 located at the lower part of the cab 6. The gyroscope 15 can stabilize the vehicle body, improve the stability of the vehicle body of the light urban delivery vehicle during the turning process, the driving process on slippery roads such as rainy and snowy days, and the collision process, effectively improve driving safety, and protect the life safety of the driver. The specific setting of the gyroscope 15 can be achieved by setting a gyroscope compartment 16 under the floor between the center console 7 and the seat 8 in the cab 6, and the gyroscope 15 can be connected to the vehicle body 1 through a bearing; a gyroscope compartment door 17 is hinged at the top compartment of the gyroscope compartment 16 through a hinge, and the gyroscope compartment door 17 can be opened upward around the hinge, which is convenient for repairing or replacing the gyroscope 15, and a common locking structure such as a latch or a buckle is provided between the gyroscope compartment door 17 and the vehicle body 1.

[0039] like Figure 3-6As shown, a crossbeam 18 is provided on the door frame 10, which can further enhance the rigidity of the side of the vehicle body 1 and increase driving safety when the door is closed. Each door frame 10 is equipped with a door handle 13, which plays the role of opening or locking the door. The door is connected to the vehicle body 1 through a hinge. The crossbeam 18 is provided with a storage bin 181, which opens toward the interior of the vehicle. The storage bin 181 is opened on the inner side and a door fixing shaft 182 is provided at the opening. The door fixing shaft 182 is fixed as one body with the crossbeam 18. The door fixing shaft 182 is respectively hinged with an upper hatch door 183 and a lower hatch door 184 for covering the upper and lower parts of the opening of the storage bin 181. Both the upper hatch door 183 and the lower hatch door 184 can be opened and closed around the door fixing shaft 182. The storage bin 181 can be provided with handles on the upper door 183 and the lower door 184, and door locks can be provided between the upper door 183 and the lower door 184 and the crossbeam 18, and the folding door curtain includes an upper folding door curtain 185 which is provided in the upper part of the storage bin 181 and can be unfolded through the upper part of the opening of the storage bin 181 to block the upper part of the door frame 10, and a lower folding door curtain 186 which is provided in the lower part of the storage bin 181 and can be unfolded through the lower part of the opening of the storage bin 181 to block the lower part of the door frame 10. The upper folding door curtain 185 and the lower folding door curtain 186 are folded and placed in the storage bin 181, and an inner fixed shaft 187 can be set in the storage bin 181. One end of the upper folding door curtain 185 and the lower folding door curtain 186 is fixed to the inner fixed shaft 187 and the other end can be pulled out of the storage bin 181 to unfold. A connecting device is set between the upper folding door curtain 185 and the lower folding door curtain 186 and the door frame 10. The connecting device can be used to connect the edges of the upper folding door curtain 185 and the lower folding door curtain 186 and the inner side of the door. A matching zipper 188 is separately provided, and the zipper 188 on the edge of the door curtain is tightened with the matching zipper 188 on the inner side of the vehicle door to form a closed vehicle door, so that a closed space is formed in the cab 6, which improves the comfort inside the vehicle in rainy, snowy or windy weather, protects against wind and rain, and keeps warm, and can also improve the isolation of external smoke and viruses in a complex external environment; the connecting device can also adopt a matching nylon Velcro or snap fastener structure provided on the edges of the upper folding door curtain 185 and the lower folding door curtain 186 and the inner side of the vehicle door.

[0040] like Figure 1-2As shown, the electric travel system includes two front wheels 19 respectively arranged on both sides of the bottom of the front end of the vehicle body 1 and two rear wheels 20 arranged in the middle of the bottom of the rear end of the vehicle body 1. Both the front wheels 19 and the rear wheels 20 are composed of tires and wheel hubs. The steering device is connected to control the two front wheels 19 to steer, and the two rear wheels 20 are connected to the electric drive system. The traditional steering and power layout of the front wheel 19 steering and the rear wheel 20 driving is in line with the driving habits of most drivers. And unlike ordinary electric bicycles and electric motorcycles, this light urban delivery vehicle adopts a four-wheel design, which increases the contact area between the wheels and the ground while increasing the force fulcrum to achieve the effect of increasing adhesion and support points and improving driving stability. The two front wheels 19 are located on both sides of the bottom of the front end of the vehicle body 1 for steering, and the wheelbase between the two front wheels 19 is approximately the width of the vehicle body 1, which increases the support for the vehicle body 1 and the stability of sharp turns and forward sliding. The two rear wheels 20 are located in the middle of the bottom of the rear end of the vehicle body 1. The wheelbase between the two rear wheels 20 is smaller and is used for driving. Under the premise of ensuring that the contact area with the ground is conducive to driving, the light urban delivery vehicle is similar to the arrangement of a reverse three-wheeler, which not only reduces the size of the vehicle, but also facilitates the flexibility and lightness of reversing.

[0041] like Figure 7-9 and Fig.12As shown, the steering device includes a central steering shaft 21 passing through the center console 7, and a steering wheel is installed on the upper end of the central steering shaft 21. The steering wheel includes a circular steering wheel and a handle-shaped steering wheel, and the two sides of the steering wheel are respectively provided with a front gripping part, a middle gripping part and a rear gripping part from front to back, especially the handle-shaped steering wheel is provided with the above three gripping parts. The arrangement of the three gripping parts enables the steering wheel 211 to provide at least three gripping methods to adapt to the driving habits of different drivers and the driving posture under different driving conditions, providing the driver with a more comfortable driving experience. The steering wheel is provided with a mobile phone card slot 212, which plays the role of fixing the mobile phone, making it convenient for the driver to place different types of mobile phones, perform navigation, order taking and other operations while driving, and facilitate the driver to check information at any time without excessively deviating the driving line of sight, thereby improving driving safety; the mobile phone card slot 212 is provided with a charging interface, which can charge the mobile phone. And it can be connected to the light city delivery vehicle control system through the charging interface, so that the mobile phone can display the speed, power consumption, tire pressure and other status data of the light city delivery vehicle, which is convenient for the driver to grasp the vehicle status information in real time and make timely adjustments when necessary. The lower end of the central steering shaft 21 is connected to the steering double fork shaft 213, and the two front wheels 19 are respectively rotatably mounted on the lower end of the steering double fork shaft 213; the lower side of the central console 7 is located on both sides of the central steering shaft 21 and is respectively provided with storage compartments 24 for placing disinfection containers and water bottles. For example, the storage compartment 24 on the left hand side of the driver is placed with a matching water bottle, which is convenient for the driver to take and drink at any time, and the storage compartment 24 on the right hand side of the driver is placed with a matching disinfectant bottle, which is convenient for the driver to take and disinfect at any time. Other items can also be placed in the storage compartment 24 according to the driver's license. The front turn signal 4 is installed on the outside of the steering double fork shaft 213, and the rear turn signal 5 is installed on both sides of the top rear end of the vehicle body 1, which can play an obvious reminder role when turning. The two front wheels 19 are respectively connected to two separate steering double-fork shafts 213 through bearings. The lower end of the central steering shaft 21 can be directly connected to the steering double-fork shaft 213. The steering wheel drives the central steering shaft 21 and the steering double-fork shaft 213 to rotate synchronously. The steering double-fork shaft 213 can also be rotatably installed on the vehicle body 1, and the central steering shaft 21 and the steering double-fork shaft 213 are connected by a swing transmission mechanism. The swing transmission mechanism is driven to work by rotating the central steering shaft 21. The swing transmission mechanism drives the steering double-fork shaft 213 to rotate and drive the two front wheels 19 to swing to achieve steering. The above two steering structures are both common structures and will not be introduced in detail here. The two steering double-fork shafts 213 steer synchronously without restricting each other, so that the two front wheels 19 can obtain a larger steering angle to reduce the turning radius of the delivery vehicle and increase the flexibility of the vehicle body. At the same time, compared with the steering of a single front wheel 19, the stability is stronger. The two rear wheels 20 can be provided with a supporting bridge 25 at the rear bottom of the vehicle body 1. An electric motor is mounted on the supporting bridge 25, and the supporting bridge 25 plays the role of fixing and shock absorption.The two rear wheels 20 are rotatably mounted on both sides of the supporting bridge 25 and are transmission-connected to the motor, or the two rear wheels 20 are directly rotatably mounted on the output shafts on both sides of the motor.

[0042] like Figure 7-9 As shown, the seat 8 includes a base 81 arranged at the rear of the cab 6 and a seat cushion arranged on the base 81. A seat cushion compartment 82 with an opening at the top is arranged at the rear of the base 81. The seat cushion includes a first seat cushion 83, a second seat cushion 84 and a third seat cushion 85 which are hinged in sequence, and the swing angles between the seat cushions can be increased by connecting the connecting rods; a locking mechanism such as a locking mechanism for adjusting the car seat 8 or a locking mechanism in which a socket and a latch cooperate, which are commonly known locking mechanisms, can be arranged at the hinge; the first seat cushion 83 is hinged to the top of the front end of the base 81, and the third seat cushion 85 can be swung and inserted into the seat cushion compartment 82. Through the adjustment and deformation of the seat cushion of the seat 8, the seat 8 will present three forms and provide three comfortable ways to meet the needs of two or less people in different usage scenarios, namely: one adult riding, two adults riding, and one adult and a child riding. The specific conversion between the three riding methods is:

[0043] 1. If Fig. 9 As shown in a, the first seat cushion 83 is kept horizontal, and the second seat cushion 84 and the third seat cushion 85 are adjusted to stand up and adjusted to a comfortable posture in sequence, and tightened by the locking mechanism, so as to provide a comfortable and safe riding mode for an adult, and the storage compartment 181 of the rear section of the vacant seat 8 base 81 can temporarily store sundries;

[0044] 2. If Fig. 9 As shown in b, the first cushion 83 and the second cushion 84 are kept level, and the third cushion 85 is stored in the storage compartment 181 at the rear section of the seat base 81 by adjusting, so that the seat 8 is unfolded to the maximum seating space, which can provide a comfortable and safe seating for two adults;

[0045] 3. Fig. 9 As shown in c, the first cushion 83 and the second cushion 84 are kept horizontal, and the third cushion 85 is adjusted to stand up and adjusted to a comfortable position, so that a comfortable and safe riding mode can be provided for an adult and a child. The relatively contracted riding space is more enveloping for the child, and is safer and more reliable. Compared with the existing electric delivery vehicle seat 8, which generally tends to carry two adults, the comfort is poor and there is no leaning function. In this way, the seat size suitable for children to sit on can be adjusted by seat deformation, which can better "clamp" the child, so that good protection is provided when carrying the child. This light urban delivery vehicle provides good protection when carrying the child.

[0046] like Figure 8As shown, the electric drive system includes a battery compartment 26 with a top opening arranged in the front side of the seat cushion compartment 82 in the base 81, so that the battery compartment 26 of the light urban delivery vehicle is located under the seat 8 and in the base 81 of the seat 8.
