[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0045] See also Figures 1 to 8 The embodiment of the present disclosure provides a garbage truck, including: a vehicle body 100, which includes a chassis structure 110, the chassis structure 110 includes a front chassis part and two mutually parallel longitudinal beams 111 extending integrally from the rear of the front chassis part, and a space area 112 is formed between the two longitudinal beams 111.

[0046] The trash bin 200 is allowed to be located in the space area 112 and is detachably connected to the longitudinal beam 111; wherein, the trash bin 200 is used to store trash, and the vehicle body 100 is used to transport the trash bin 200. It should be noted that the trash bin 200 and the vehicle body 100 are arranged in a split type; preferably, the transverse cross-section of the trash bin 200 is a funnel-shaped structure that is wide at the top and narrow at the bottom, and the inclined surface at the upper end of the funnel is a trash entry and collection channel. This structure can facilitate the trash bin 200 to enter the space area 112 formed between the two longitudinal beams 111 and can form a stable support.

[0047] Specifically, the vehicle body 100 includes a chassis structure 110, and the trash bin 200 is connected to the chassis structure 110. In this embodiment, the chassis structure 110 includes at least two longitudinal beams 111 parallel to each other, and a space area 112 is provided between the two longitudinal beams 111. The trash bin 200 is allowed to be located in the space area 112 and is detachably connected to the longitudinal beams 111. In actual use, when the trash bin 200 needs to be transported, the vehicle body 100 is inverted so that the trash bin 200 enters the space area 112.

[0048] Optionally, the garbage truck of the present invention drives the front wheels with an internal combustion engine and / or drives the rear wheels with an electric motor; when the rear wheels are electrically driven, the motor can be a hub motor to reduce the distance from the rear tire tread to the longitudinal beam.

[0049] When the trash bin 200 enters the space area 112 , the lifting assembly 300 relatively fixes the trash bin 200 and the longitudinal beam 111 , thereby locking the trash bin 200 and the longitudinal beam 111 .

[0050] There are at least two lifting assemblies 300 , which are respectively disposed on the longitudinal beam 111 , and are used to lock or unlock the trash bin 200 , and the trash bin 200 can be lifted in the locked state.

[0051] In some embodiments, the lifting assembly 300 includes a tongue 310 and a driving mechanism 320, and the tongue 310 is connected to the driving mechanism 320. There are multiple lifting assemblies 300, and the multiple lifting assemblies 300 can be divided into two groups. One group of lifting assemblies 300 is located on the longitudinal beam 111 on one side, and the other group of lifting assemblies 300 is located on the longitudinal beam 111 on the other side. The lifting assemblies 300 on the two longitudinal beams 111 can be symmetrically arranged, thereby improving the stability of the trash can 200 during the connection process.

[0052] Furthermore, the tongue 310 can be engaged with the bottom of the trash bin 200, and the driving mechanism 320 is used to drive the tongue 310 to engage with the bottom of the trash bin 200 and lift the trash bin 200. The lifting assembly 300 also includes a controller, which is electrically connected to the driving mechanism 320 and is used to adjust the state of the driving mechanism 320. Therefore, when the trash bin 200 reaches the designated position in the space area 112, the tongue 310 is engaged with the bottom of the trash bin 200. The trash bin 200 is lifted by the driving mechanism 320 to ensure that the vehicle body 100 can travel normally.

[0053] It is understandable that a plurality of sensing units may be connected to the vehicle body 100, and the sensing units are used to sense the specific position of the trash bin 200 in the space area 112. The controller is also electrically connected to the driving mechanism 320, and is used to adjust the state of the driving mechanism 320 according to the sensing signal of the sensing unit. Therefore, the sensing signal of the sensing unit is used to determine the lifting time of the trash bin 200.

[0054] In some embodiments, the driving mechanism 320 further includes a support seat 321, a connecting arm 322, and a driving assembly. The support seat 321 is fixedly connected to the outer side of the longitudinal beam 111, and a round hole slideway 3210 is provided on the support seat 321. The connecting arm 322 includes a shaft body 3220 and a connecting portion 3221, and the shaft body 3220 is located in the round hole slideway 3210. The connecting portion 3221 is fixedly connected to the end of the shaft body 3220, and the tongue 310 is connected to the connecting portion 3221. The tongue 310 and the connecting portion 3221 can be fixedly connected or slidably connected.

[0055] It can be understood that the driving assembly includes a first driving unit and a second driving unit, the first driving unit is used to drive the shaft body 3220 to slide in the circular hole slide 3210, and the second driving unit is used to drive the tongue 310 to engage with the bottom of the trash can 200.

[0056] For example, in one embodiment, the first driving unit is fixedly connected to the longitudinal beam 111, and the first driving unit is used to drive the shaft body 3220 to slide along the circular hole slide 3210. The second driving unit is fixedly connected to the longitudinal beam 111, and is used to drive the shaft body 3220 to rotate along the circular hole slide 3210. At this time, the tongue 310 and the connecting portion 3221 are fixedly connected. The rotation of the shaft body 3220 in the circular hole slide 3210 allows the tongue 310 to avoid the space area 112. Therefore, after the trash bin 200 enters the space area 112, the second driving unit drives the shaft body 3220 to rotate, so that the tongue 310 enters the space area 112 and engages with the bottom of the trash bin 200.

[0057] Alternatively, in another embodiment, the first driving unit is fixedly connected to the longitudinal beam 111, and the first driving unit is used to drive the shaft body 3220 to slide along the circular hole slideway 3210. The second driving unit is fixedly connected to the connecting portion 3221, and is used to drive the tongue 310 to slide relative to the connecting portion 3221. At this time, the tongue 310 and the connecting portion 3221 are in sliding connection. By sliding the tongue 310 on the connecting portion 3221 toward the outside of the space area 112, the tongue 310 can avoid the space area 112. Therefore, after the trash bin 200 enters the space area 112, the second driving unit drives the tongue 310 to move toward the inside of the space area 112, so that the tongue 310 enters the space area 112 and engages with the bottom of the trash bin 200.

[0058] It should be noted that the first drive unit and the second drive unit are one or a combination of mechanical, hydraulic, pneumatic or electric. However, it is not limited thereto and can be determined according to actual needs.

[0059] In some embodiments, the sensor unit is a contact sensor or a non-contact sensor, and the sensor unit is fixedly connected to the vehicle body 100. Therefore, when the trash bin 200 reaches the designated position in the space area 112, an arrival instruction is issued through the sensor unit.

[0060] A locking mechanism is provided at the bottom of the trash bin 200. When the tongue 310 is engaged with the bottom of the trash bin 200, the locking mechanism can be triggered. For example, when the tongue 310 is located at a preset limited position, the locking mechanism is triggered, and the locking mechanism generates and sends a locking signal to the controller. Since the controller is connected to the locking mechanism by telecommunication, the control allows the vehicle body 100 to be started and transported only after the locking signal is obtained.

[0061] Furthermore, the locking mechanism may be a limit sensor, and the limit sensor is communicatively connected with the controller.

[0062] Specifically, in actual use of the device, the vehicle body 100 moves backward until it touches the front structure of the trash bin 200 and the contact sensor or the non-contact sensor, and then stops, and the tongue 310 extends outward to a limited position, or the hook arm drives the tongue 310 to rotate to a limited position. The locking mechanism generates a locking signal and transmits it to the controller, which drives the shaft body 3220 to move upward, and stops when it reaches or exceeds a limited position that does not affect the vehicle's passability (the minimum gap between the rigid part and the ground).

[0063] When the locking and upward movement are completely in place, the operating function of the chassis structure 110 is unlocked through the controller, and the vehicle can move.

[0064] In some embodiments, the longitudinal beam 111 is further connected to an outer cover 120, and a guide structure 121 is provided at the openings at the rear ends of the longitudinal beam 111 and the outer cover 120. The guide structure 121 is provided in the passage to facilitate the trash can 200 to enter the space area 112 smoothly.

[0065] For example, the guide structure 121 may be a conical surface or an arc surface, but is not limited thereto and may be determined according to actual needs. The guiding effect of the conical surface or the arc surface greatly facilitates the trash can 200 to enter the space area 112.

[0066] Furthermore, in order to improve the safety of the device in actual use and prevent the trash can 200 from falling from the rear of the vehicle body 100, a rear door 130 is connected to the rear end of the outer shell 120. The rear door 130 and the outer shell 120 can be hydraulically driven, and the rear door 130 and the outer shell 120 are opened upwards to facilitate the trash can 200 to enter the space area 112 smoothly.

[0067] Furthermore, in order to improve the structural strength of the trash bin 200 during actual use, a plurality of longitudinal reinforcing ribs 210 and a plurality of transverse reinforcing ribs 220 are provided at the bottom of the trash bin 200, and the longitudinal reinforcing ribs 210 are interlaced with the transverse reinforcing ribs 220. For example, in some embodiments, the longitudinal reinforcing ribs 210 include at least two, and the two longitudinal reinforcing ribs 210 are provided in parallel. At the same time, the transverse reinforcing ribs 220 include three, and the three transverse reinforcing ribs 220 are connected to the longitudinal reinforcing ribs 210.

[0068] In some embodiments, in order to improve the control effect of the garbage truck, a remote control unit is also allowed to be included. The remote control unit includes a receiving module and a sending module, and the receiving module is communicatively connected with the sending module, and the receiving module is electrically connected to the controller.

[0069] Therefore, the receiving module can be used to obtain the signal instruction sent by the sending module, and the controller performs a corresponding action based on the control instruction.

[0070] Optionally, a locking rod (not shown) is detachably connected between the rear ends of the two longitudinal beams 111 of the garbage truck of the present invention, and at least one end of the locking rod is detachably and movably fixed to one or both longitudinal beams 111, and is used to further lock and limit the garbage bin 200 when the garbage bin 200 enters the space area 112. On the one hand, it can prevent the garbage bin 200 from sliding out from the rear of the space area 112 during transportation, especially when going uphill; on the other hand, it can also prevent the garbage bin 220 from detaching from the longitudinal beam 111 due to the large torque borne by the longitudinal beam when the garbage truck turns, and can further improve the connection stability between the garbage bin 220 and the longitudinal beam 111; in addition, by providing a locking rod, even in the absence of an aggregate box, the two longitudinal beams 111 can be fixedly connected together and always kept parallel and balanced, thereby ensuring stable driving of the vehicle even when turning and other road conditions.

[0071] In addition, optionally, in some embodiments, at least two elastic limit pins and limit slot assemblies that are electrically or manually controlled are further provided between the rear beam 111 and the trash bin, for further realizing that when the trash bin 200 is embedded in the space area 112 between the two longitudinal beams 111, it can form a stable connection with the longitudinal beams 111, thereby sharing or bearing the torque between the rear beams 111.

[0072] In summary, the present disclosure discloses a garbage truck, in which the tongue 310 is engaged with the bottom of the garbage bin 200, and the driving mechanism 320 drives the tongue 310 to engage with the bottom of the garbage bin 200 and lift the garbage bin 200. By setting the chassis structure 110 and connecting the garbage bin 200 to the chassis structure 110, the center of gravity of the garbage bin 200 and the entire vehicle is low, reducing the safety hazard of tipping due to a high center of gravity. Through the locking structure, the locking mechanism can be triggered when the tongue 310 is located at a preset limited position, and a locking signal is generated. The controller allows the vehicle body 100 to be started and transported only after obtaining the locking signal, which can effectively improve the safety of the device during use.

[0073] Therefore, the existing garbage trucks modified based on the second-class automobile chassis have high center of gravity and high safety hazards during driving and loading and unloading, which can be effectively improved. Therefore, the present invention effectively overcomes some practical problems in the prior art and has high utilization value and use significance.
