Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of carrying equipment, in particular to a carrying vehicle. BACKGROUND

[0002] The carrying vehicle is commonly used for transporting fruits, vegetables, minerals and building materials. The existing carrying vehicle usually comprises a vehicle body and a wheel structure installed on the vehicle body. The vehicle body can be used to carry goods, and the wheel structure is installed on both sides of the vehicle body. When the carrying vehicle is manually pushed or driven by an electric motor, the transportation of products can be realized.

[0003] For example, the Chinese patent with publication number CN215622375U discloses an airport heavy equipment carrying vehicle. The rear part of the chassis 1 is provided with a rear shock-absorbing suspension, and the lower part of the rear shock-absorbing suspension is provided with a walking wheel 11. The front part of the chassis 1 is provided with a steering machine 12, and the lower part of the steering machine 12 is provided with a front shock-absorbing suspension. The lower part of the front shock-absorbing suspension is provided with a steering wheel 13. A traction frame 14 is installed on the axle of the steering wheel 13. The traction frame 14 can be connected with a trailer, so that the airport heavy equipment carrying vehicle can be manually pushed or pulled, or towed by a towing vehicle.

[0004] Although the above-mentioned carrying vehicle can reduce the vibration caused by the uneven ground through the shock-absorbing suspension, it is difficult to adapt to the more steep terrain in mountainous areas. When the ground slope is large, the front end of the traction frame is easy to cause the front wheel to separate from the ground during traction, affecting the operation of the carrying vehicle, and even causing the carrying vehicle to tip over.

[0048] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0049] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] See Figures 1 to 5 This utility model provides a transport vehicle, including a vehicle body 1, fixed wheel assemblies 2, rocker arm wheel assemblies 3, a cargo loading assembly 4, an electronic control assembly 5, and a traction assembly 6. At least two fixed wheel assemblies 2 are provided, and the two fixed wheel assemblies 2 are symmetrically distributed on both sides of the vehicle body 1. At least two rocker arm wheel assemblies 3 are provided, and the two rocker arm wheel assemblies 3 are symmetrically distributed on both sides of the vehicle body 1. The cargo loading assembly 4 is detachably installed under the vehicle body 1. The electronic control assembly 5 and the traction assembly 6 are both installed on the top of the vehicle body 1, and at least the electronic control assembly 5 is located directly above the cargo loading assembly 4.

[0052] It is easy to understand that in the above scheme, by placing the loading assembly 4 at the lower end of the vehicle body 1 and the traction assembly 6 at the upper end of the vehicle body 1, on the one hand, the vehicle body 1 can limit the items loaded in the loading assembly 4; on the other hand, the traction force applied by the traction assembly 6 to the vehicle body 1 acts on the middle position of the entire transport vehicle, effectively preventing the transport vehicle from tipping over during traction. Furthermore, the cooperation between the fixed wheel assembly 2 and the rocker arm wheel assembly 3 ensures the stability of the transport vehicle to a certain extent and allows it to adapt to rough terrain. In addition, it should be understood that the vertical distribution of the electronic control assembly 5 and the loading assembly 4 helps maintain the balance of the entire transport vehicle and prevents the loaded goods from affecting or interfering with the electronic control assembly 5 during loading.

[0053] Specifically, the fixed wheel assembly 2 includes a first wheel section 21; the rocker arm wheel assembly 3 includes a rocker arm frame 31, and a second wheel section 32 and a third wheel section 33 respectively installed at both ends of the rocker arm frame 31; the first wheel section 21, the second wheel section 32, and the third wheel section 33 are arranged sequentially along the side of the vehicle body 1; the first wheel section 21 and the third wheel section 33 are configured as driven wheel sections, the second wheel section 32 is configured as a driving wheel section, and the second wheel section 32 is communicatively connected to the electronic control assembly 5.

[0054] It is easy to understand that by using the symmetrically arranged active wheel section (i.e., the second wheel section 32 in this embodiment), the left and right differential steering of the entire transport vehicle can be realized. At the same time, the active wheel section is located in the middle position on the side of the vehicle body 1, which can ensure the flexibility of the transport vehicle in turning in narrow spaces.

[0055] See Figure 1 and Figure 2 In order to further ensure the smooth operation and steering of the transport vehicle, in this embodiment, the first wheel part 21 and the third wheel part 33 are located on the same vertical plane; the second wheel part 32 is located on the side of the vertical plane where the third wheel part 33 is located away from the load assembly 4.

[0056] See Figures 1 to 4 The rocker arm 31 includes a rocker arm 311 and connecting arms 312 fixedly installed at both ends of the rocker arm 311; the rocker arm 311 is rotatably connected to the vehicle body 1 through a U-shaped hinge seat assembly 7; the lower end of one connecting arm 312 is connected to the second wheel part 32, and the lower end of the other connecting arm 312 is connected to the third wheel part 33.

[0057] Specifically, the U-shaped hinge assembly 7 includes a first U-shaped seat 71, a second U-shaped seat 72, and a hinge shaft 73. The first U-shaped seat 71 is fixedly connected to the rocker arm 311, and the second U-shaped seat 72 is fixedly connected to the vehicle body 1. The side walls of the first U-shaped seat 71 and the second U-shaped seat 72 abut against each other, and the first U-shaped seat 71 and the second U-shaped seat 72 are rotatably connected by the hinge shaft 73.

[0058] See Figures 1 to 4 In this embodiment, the drive wheel section (i.e., the second wheel section 32) includes a drive wheel 321 and a hub motor 322. The drive shaft of the hub motor 322 is connected to the drive wheel 321, and the hub motor 322 is connected to the electronic control component 5 via wires, thereby ensuring the stability of the hub motor 322 control. Furthermore, it is worth noting that the electronic control component 5 can control the two symmetrically arranged hub motors 322, thereby controlling the drive wheels 321 on both sides of the vehicle body 1 to have different rotational speeds, thus achieving wheel steering.

[0059] Furthermore, in order to facilitate wire routing, the transport vehicle also includes a wiring structure 8, which includes a first wire groove 81, a first wire opening 82, a second wire groove 83, and a second wire opening 84; the first wire groove 81 and the first wire opening 82 are disposed on the rocker arm 31, and the second wire groove 83 and the second wire opening 84 are disposed on the vehicle body 1.

[0060] See Figure 1 and Figure 5 The wheel fixing assembly 2 also includes a fixing frame 22 and a triangular support frame 23. One end of the fixing frame 22 is fixedly installed at the lower end of the vehicle body 1 and connected to the lower end surface of the vehicle body 1 through the triangular support frame 23. The other end is connected to the first wheel part 21.

[0061] Furthermore, at least two triangular support frames 23 are provided, and the two triangular support frames 23 are vertically distributed, which can increase the stability of the connection of the triangular support frames 23.

[0062] Furthermore, along the traction direction of traction component 6 (i.e. Figure 1 (as shown in the Q1 direction) or in the opposite direction of traction (i.e.) Figure 1 In the direction of Q2 shown, one of the triangular support frames 23 and the projection of the cargo bin 41 overlap, so that the triangular support frame 23 can support the cargo bin 41 in some cases (such as when the locking element 43 is not installed on the uphill section or when the locking element 43 fails).

[0063] See Figure 1 , Figure 2 and Figure 5 The traction assembly 6 includes a winch 61, a traction rope 62, and a limiting structure 63. One end of the traction rope 62 is connected to the winch 61, and the other end is provided with a loop 621. The limiting structure 63 includes a mounting base 631, and a transverse limiting shaft 632 and a longitudinal limiting shaft 633 mounted on the mounting base 631. The mounting base 631 is fixed to the vehicle body 1. There are two transverse limiting shafts 632, which are located on the transverse sides of the traction rope 62 respectively. There are two longitudinal limiting shafts 633, which are located on the longitudinal sides of the traction rope 62 respectively, thereby guiding and limiting the traction rope 62.

[0064] See Figure 1 and Figure 2 The transport vehicle provided in this embodiment also includes a protective cover 9, which covers at least a portion of the periphery of the electronic control component 5; the protective cover 9 can separate the electronic control component 5 from the traction component 6, and prevent the traction component 6 from affecting the electronic control component 5.

[0065] See Figures 1 to 3The loading assembly 4 includes a loading hopper 41, a support block 42, and a locking member 43; the edge of the loading hopper 41 partially abuts against the support block 42; the locking member 43 can fix the edge of the loading hopper 41 to the support block 42.

[0066] In this embodiment, the locking member 43 is a tiger clamp. Of course, in other embodiments, the locking member 43 can also be a bolt or screw.

[0067] Furthermore, the locking element 43 can be set on the front and rear sides of the cargo bin 41 along the vehicle's running direction (i.e., the traction direction of the traction rope 62), which can further prevent the cargo bin 41 from moving due to gravity during the operation of the traction assembly 6 towing the transport vehicle.

[0068] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
