Description

Technical Field

[0001] The present invention relates to the technical field of express delivery vehicles, and in particular to an express delivery logistics vehicle. Background Art

[0002] The modern logistics industry is the "meridian" of the economy, connected to production on one end and consumption on the other. It is an important support for extending the industrial chain, enhancing the value chain, and building the supply chain. It plays a leading, basic, and strategic role in building a modern circulation system, promoting the formation of a strong domestic market, promoting high-quality development, and building a modern economic system.

[0003] At present, there are three main types of express delivery services in densely populated areas. The first is the manual delivery method, where the courier delivers the express to the designated location and waits for the recipient to pick it up. The second is the smart express cabinet delivery method, where smart express cabinets are centrally set up in the designated area. Users can go to the smart express cabinet to enter the corresponding pickup code and complete self-service pickup. The third is the express station delivery method, where express stations are established in the designated area. Each express company temporarily stores the express parcels at the express station, and users can go directly to the express station to complete the pickup. However, there are certain defects in the above three express delivery service methods. The manual delivery method has a short pickup time, the recipients gather in the same time period, and the waiting time is long, which leads to user dissatisfaction. A courier has to deal with many recipients at the same time, the workload is large and it is easy to deliver the wrong express. For both the smart express cabinet delivery method and the express station delivery method, users need to pick up the parcels themselves, which cannot provide good services to users. Therefore, a new distribution method has emerged in the prior art, that is, express delivery through unmanned logistics vehicles. This delivery method is highly efficient and has a good user experience. However, most of the existing logistics vehicles can only travel on flat inter-city roads and have poor shock absorption capabilities. Their driving method is mostly to drive the wheels forward through the motor on the chassis, and the drives of each wheel are linked, with poor climbing ability and high requirements for roads. In addition, the vehicle body is large and not compact enough. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an express delivery logistics vehicle, which solves the problem that the existing logistics vehicles are not suitable for driving on bumpy roads.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A logistics vehicle for express transportation comprises a cargo box assembly, a shock-absorbing suspension assembly, a built-in wheel assembly, a steering assembly and a solar range-extending system; the cargo box assembly is mounted on the shock-absorbing suspension assembly, and the bottom of the shock-absorbing suspension assembly is connected to the built-in wheel assembly; a steering assembly is arranged in the shock-absorbing suspension assembly, and the steering assembly and the built-in wheel assembly are movably connected; a solar range-extending system is arranged on the top of the cargo box assembly.

[0007] In this solution, the shock-absorbing suspension assembly reduces the shock of the cargo box assembly, making the logistics vehicle suitable for driving on bumpy roads; the built-in wheel assembly drives the logistics vehicle forward, and the body structure is small; the solar range extender system uses solar energy to provide endurance support for the logistics vehicle, improving its stability and reliability, enabling it to transport at high loads for a long time, greatly improving the coverage of terminal express logistics services in remote areas.

[0008] Furthermore, the shock-absorbing suspension assembly includes a chassis, and the cargo box assembly is installed on the chassis; a shock-absorbing plate is connected to the bottom of the chassis; four shock-absorbing springs are respectively connected to the four corners of the shock-absorbing plate, and the bottoms of the four shock-absorbing springs are fixed on the suspension beam;

[0009] The built-in wheel assembly comprises four motor-built-in wheels, which are respectively arranged on four corners of the suspension beam.

[0010] In this solution, when the logistics vehicle travels on a bumpy road, the shock-absorbing springs at various positions act as elastic elements to buffer the impact of the bumps, keep the shock-absorbing plate and the chassis stable, and avoid bumps on the goods inside the cargo box assembly.

[0011] Furthermore, the wheel with built-in motor includes a wheel hub frame, one side of the wheel hub frame is connected to the suspension beam through a steering shaft, a mounting plate group is fixed to the other side of the wheel hub frame, a hub motor is fixed to the mounting plate group, and the hub motor is connected to the drive shaft through a driving gear group; one end of the drive shaft is movably connected to the mounting plate group, and the other end of the drive shaft is fixedly connected to the wheel ring; an anti-skid tire is sleeved on the outer side of the wheel ring.

[0012] In this solution, the hub motor drives the drive shaft to rotate through the drive gear set, and the drive shaft drives the wheel ring and anti-skid tire to rotate, thereby pushing the logistics vehicle forward; the hub motor of this design is installed inside the wheel, which saves space for installing the motor or drive system on the chassis, making the logistics vehicle lower and smaller in size. In addition, the four motor-built-in wheels are independently driven by their own internal hub motors, with stable power output and strong climbing ability.

[0013] Furthermore, the suspension beam includes two symmetrically structured single-sided suspension beams, which are movably connected via a connecting piece; two ends of each single-sided suspension beam are respectively connected to two motor-built-in wheels on the same side;

[0014] The steering assembly comprises two groups of single-sided steering drive assemblies, and the two groups of single-sided steering drive assemblies are respectively arranged in two single-sided hanging beams.

[0015] In this solution, the two single-sided hanging beams can rotate through the connecting parts. When encountering uneven roads, the two single-sided hanging beams can rotate relative to each other so that the motor-built-in wheels at their respective ends can contact the ground, avoiding one end of the logistics vehicle from tilting up. At the same time, it also ensures that each motor-built-in wheel can generate grip to push the vehicle body forward.

[0016] Furthermore, the single-sided steering drive assembly includes a motor box, which is installed on the single-sided hanging beam; a steering motor is installed in the motor box, which is connected to the steering power shaft through a steering gear set, and a driving wheel is connected to the bottom of the steering power shaft; the bottom of the driving wheel passes through a strip hole opened on the single-sided hanging beam and is connected to the transmission rope inside the single-sided hanging beam, one end of the transmission rope passes through the changing wheel set and is connected to the driven wheel on the steering shaft at one end of the single-sided hanging beam; the other end of the transmission rope passes through the changing wheel set and is movably connected to the pulley on the steering shaft at the other end of the single-sided hanging beam.

[0017] In this solution, the steering motor drives the driving wheel to rotate through the steering gear set, and the driving wheel drives the transmission rope to rotate. When the transmission rope rotates, it drives the steering shaft to rotate through the driven wheel on the steering shaft, thereby driving the motor-built-in wheel corresponding to the steering shaft to turn, thereby realizing the steering of the logistics vehicle. The two motor-built-in wheels at the front end of the logistics vehicle of this design are independently driven by two single-sided steering drive components, which realizes the steering without interfering with the relative rotation of the two single-sided hanging beams; the transmission rope is set inside the single-sided hanging beam, which saves space and reduces the volume of the entire shock-absorbing suspension component.

[0018] Furthermore, the cargo box assembly includes a cargo box body, which is mounted on the top of the chassis; the interior of the cargo box body is divided into a plurality of package chambers by horizontally and vertically staggered partitions; two integrated cargo box doors are respectively provided on both sides of the cargo box body; the tops of the two integrated cargo box doors are respectively slidably arranged on the slide rails on the top of the cargo box body; two hydraulic support rods are movably arranged between the integrated cargo box door on each side and the cargo box body; the two hydraulic support rods drive the integrated cargo box door on that side to move along the slide rails to close the package chamber on that side;

[0019] A paper shredding mechanism is also provided inside the cargo box body.

[0020] In this solution, multiple parcel cavities are provided inside the cargo box body. The express parcel of each recipient can be placed in a parcel cavity respectively. The capacity is large and it can also prevent the wrong express from being picked up. A shredding mechanism is provided. After picking up the express, the express note with the recipient's address and contact information can be thrown into the shredding mechanism for shredding to ensure the recipient's information security.

[0021] Furthermore, the shredding mechanism includes a shredding box, which is embedded in the cargo box body; a paper inlet is opened on one side of the shredding box; two shredding rollers are arranged inside the shredding box, and shredding blades are distributed on the two shredding rollers, and the shredding blades on the two shredding rollers are arranged in a staggered manner; the ends of the shredding rollers are connected to shredding motors, and the shredding motor is installed in a motor box fixed to the shredding box; a collection drawer is provided at the bottom of the shredding box, and rollers are provided at the bottom of the collection drawer.

[0022] In this solution, after the express delivery slip is thrown into the shredding box from the paper inlet, the shredding blades on the two shredding rollers shred it and then drop it into the collection drawer below; the collection drawer adopts a pull-out design, which is convenient for pulling it out and dumping the shredded paper inside, and is easy to use.

[0023] Furthermore, the solar range extender system includes a fixed solar panel, which is fixed to the top of the cargo box body; two flip solar panels are hinged at both ends of the fixed solar panel.

[0024] In this solution, the two flip solar panels absorb solar energy together with the fixed solar panel after being opened. The sunlight irradiation area is large and the light energy conversion efficiency is high, which makes it convenient to charge the logistics vehicle when it is not in use.

[0025] The beneficial effects of the present invention are:

[0026] In the express delivery logistics vehicle provided by the present invention, the shock-absorbing suspension assembly and the built-in wheel assembly are optimized and designed, which improves the shock-absorbing performance and power performance of the entire logistics vehicle; the suspension beam in the shock-absorbing suspension assembly is designed as two relatively rotatable single-sided hanging beams, which prevents the vehicle body from tilting when driving on uneven roads; at the same time, two sets of single-sided steering drive assemblies are respectively designed inside the two single-sided hanging beams, integrating the chassis structure. In the built-in wheel assembly, the hub motor is installed inside the wheel ring, which saves space, so that the cargo box body can have a larger design space, and adopts an independent integrated cargo box door design, which reduces manual operation time, improves loading and unloading efficiency and transportation safety, and the integrated cargo box door design occupies less internal space, which can meet the transportation needs of different scales and realize the characteristics of high storage capacity and high convenience of logistics vehicles.

[0027] A shredder is installed at the bottom of the cargo box to shred the express delivery slips to ensure the safety of the recipient's information; the collection drawer collects the broken paper scraps, which is environmentally friendly and hygienic. A solar range extension system is designed on the top of the cargo box to use solar energy for energy supply. It can be folded up to prevent damage during the journey of the logistics vehicle, and can be unfolded to increase the sunlight absorption area when it stops working.

[0028] The express transport logistics vehicle of the present invention can greatly improve the coverage rate of terminal express logistics services in remote areas; realize an unmanned delivery and user-pickup operation mode, and reduce the land demand of fixed express stations and the manpower demand for express delivery.
