[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Figure 1 , Figure 2 , Figure 3 and Figure 4A four-way carrier with a variable storage chamber is shown, comprising a main frame 1, two first electrically-controlled drive lifting wheels 2 are arranged on the left and right sides of the main frame 1, two second electrically-controlled drive lifting wheels 3 are arranged on the front and rear sides of the main frame 1, an electrically-controlled liftable internal loading compartment 4 is arranged inside the main frame 1, and an electrically-controlled rotating bottom control bracket 5 is movably installed at the bottom of the electrically-controlled liftable internal loading compartment 4.

[0031] The left and right sides and the front and rear sides of the main frame 1 of the four-way carrier are respectively provided with a first electrically controlled driving lifting wheel 2 and a second electrically controlled driving lifting wheel 3, which can help the frame move in different directions. The electrically controlled lifting internal loading compartment 4 arranged inside the main frame 1 can be raised and lowered according to the size of the cargo, thereby solving the problem of loading cargo of different sizes. The electrically controlled rotating bottom control bracket 5 at the bottom of the loading compartment can flexibly adjust and control the position of the cargo, further improving the flexibility and accuracy of loading.

[0032] The left and right sides and the front and rear sides of the main frame 1 of the four-way carrier are respectively provided with a first electrically controlled driving lifting wheel 2 and a second electrically controlled driving lifting wheel 3, which can help the frame move in different directions. The electrically controlled lifting internal loading compartment 4 arranged inside the main frame 1 can be raised and lowered according to the size of the cargo, thereby solving the problem of loading cargo of different sizes. The electrically controlled rotating bottom control bracket 5 at the bottom of the loading compartment can flexibly adjust and control the position of the cargo, further improving the flexibility and accuracy of loading.

[0033] Specifically, the main frame 1 of the four-way carrier is provided with four electrically controlled driving lifting wheels on the left and right sides and the front and rear sides respectively, and these driving lifting wheels are controlled by an electric control system to achieve multi-directional movement and adjustment. The electrically controlled liftable internal loading compartment 4 inside the main frame 1 is height-adjusted by an electrically controlled lifting system to meet the loading requirements of goods of different sizes. The electrically controlled rotating bottom control bracket at the bottom of the loading compartment is used to achieve precise adjustment of the position of the goods through an electrically controlled rotating system.

[0034] Compared with the prior art, the four-way carrier of the present application realizes the function of rapid adjustment according to the size of the cargo by setting the electrically controlled liftable internal loading cabin 4 and the electrically controlled rotating bottom control bracket 5, thus solving the problem of the existing four-way carrier having a single loading method and poor adaptability. At the same time, by setting the electrically controlled drive lifting wheels, the four-way carrier can be flexibly moved in different directions, thus improving the handling efficiency and safety.

[0035] Therefore, the present application realizes the function of rapid adjustment according to the size of the cargo by setting an electrically controlled liftable internal loading compartment 4 and an electrically controlled rotating bottom control bracket 5 on the main frame 1 of the four-way carrier, thereby solving the problem that the existing four-way carrier cannot be quickly adjusted when loading cargo. At the same time, by setting the electrically controlled drive lifting wheels, the four-way carrier can be flexibly moved in different directions, thereby improving the handling efficiency and safety.

[0036] In order to cooperate with the flip adjustment control, the first electrically-controlled driven lifting wheel 2 and the second electrically-controlled driven lifting wheel 3 are both composed of a flip adjustment arm 231 movably installed on the lateral outer wall of the main frame 1, a supporting driving wheel 232 movably installed at the bottom end of the flip adjustment arm 231 and a lateral electrically-controlled support rod 233 for controlling the flipping of the flip adjustment arm 231.

[0037] The first electrically controlled driving lifting wheel 2 and the second electrically controlled driving lifting wheel 3 are movably mounted through the flip adjustment arm 231, the supporting driving wheel 232 and the lateral electrically controlled support rod 233. The flip adjustment arm 231 can be flipped by the control of the lateral electrically controlled support rod 233, thereby adjusting the position of the supporting driving wheel 232. This design can adapt to different sizes of goods by adjusting the position of the flip arm 231, increase the height of the four-way vehicle, improve applicability, and solve the problem that the four-way vehicle cannot be quickly adjusted according to the size of the goods when loading goods.

[0038] The flip adjustment arm 231 can achieve precise flipping movement through the control of the lateral electric control support rod 233, so that the position of the support drive wheel 232 can be quickly adjusted according to the size of the goods. Specifically, the length and angle of the lateral electric control support rod 233 can be adjusted as needed, thereby changing the angle and position of the flip adjustment arm 231. The support drive wheel 232 can support the goods at different heights and positions through the adjustment of the flip adjustment arm 231 to ensure the stability and safety of the goods. As a preferred embodiment, the control system of the flip adjustment arm 231 and the lateral electric control support rod 233 can be integrated into the electric control system of the four-way vehicle, which is convenient for the operator to perform unified control.

[0039] Therefore, the present application realizes the function of the four-way vehicle being able to quickly adjust according to the size of the cargo when loading cargo by introducing the design of the flip adjustment arm 231, the supporting driving wheel 232 and the lateral electric control support rod 233. Compared with the prior art, the technical solution of the present application not only improves the applicability and flexibility of the four-way vehicle, but also effectively solves the problems existing in the prior art such as the single loading method, limited lateral limiting capacity and inability to adjust the height. Through this design, the four-way vehicle can better adapt to cargo of different sizes and shapes, and improve the efficiency of storage and handling.

[0040] In order to facilitate lateral adjustment, an outer lifting adjustment slot 6 is provided on the inner side of the main frame 1 at the connection end of the electrically controlled liftable internal loading compartment 4 .

[0041] The technical features include an outer lifting adjustment groove 6 on the inner side of the main frame 1 and the connecting end of the electrically controlled liftable internal loading compartment 4. The outer lifting adjustment groove 6 plays a key role in solving the lifting and adjusting problem of the internal loading compartment of the four-way carrier. By arranging the outer lifting adjustment groove 6 on the inner side of the main frame 1, the electrically controlled liftable internal loading compartment 4 can be lifted and adjusted on the inner side of the main frame 1, thereby realizing the height adjustment of the internal loading compartment to meet the loading requirements of different goods.

[0042] The outer lifting adjustment groove 6 can adopt a variety of structural forms, for example, it can be designed as a linear guide groove, or even a multi-stage lifting groove to adapt to different lifting requirements. Specifically, the outer lifting adjustment groove 6 can be formed by machining or casting to ensure its strength and precision. Furthermore, a lubrication device can be set in the groove to reduce friction and improve the stability and efficiency of lifting. In addition, the size and shape of the outer lifting adjustment groove can be customized according to actual needs to adapt to different specifications of the electrically controlled liftable internal loading compartment 4.

[0043] By setting the outer lifting adjustment groove 6 on the inner side of the main frame 1, the electrically controlled liftable internal loading compartment 4 can be lifted and lowered on the inner side of the main frame, thereby realizing the height adjustment of the internal loading compartment to meet the loading requirements of different goods. Compared with the prior art, the technical solution proposed in this application can effectively solve the problem that the height of the internal loading compartment of the four-way transport vehicle cannot be adjusted, improves the adaptability and functionality of the transport vehicle, and can better meet the loading requirements of different goods.

[0044] In order to facilitate adjustment, the electrically-controlled liftable internal loading compartment 4 includes an inner lift support cover 41 , a middle lift cover 42 , an outer lift cover 43 , a first electrically-controlled lift component 44 , a second electrically-controlled lift component 45 and a third electrically-controlled lift component 46 .

[0045] The electrically controlled liftable internal loading compartment realizes the lifting and adjusting function of the internal loading compartment through the cooperation of the inner lifting support cover 41, the middle lifting cover 42, the outer lifting cover 43, and the three electrically controlled lifting components. The inner lifting support cover 41, the middle lifting cover 42, and the outer lifting cover 43 are respectively connected to the first, second, and third electrically controlled lifting components, so that the internal loading compartment can be lifted and adjusted as needed, thereby improving the adaptability and functionality of the four-way carrier.

[0046] Therefore, the present application solves the problem that the internal loading compartment of the four-way carrier in the prior art cannot be raised or lowered by adopting the electrically controlled liftable internal loading compartment 4. Through the cooperation of the inner lifting support cover 41, the middle lifting cover 42, the outer lifting cover 43 and the electrically controlled lifting assembly, the flexible lifting of the internal loading compartment is achieved, and it can be quickly adjusted according to the size and shape of the goods, thereby improving the adaptability and functionality of the four-way carrier. Compared with the prior art, the technical solution of the present application significantly improves the diversity and convenience of cargo loading, and enhances the operational performance of the four-way carrier in a small space.

[0047] In order to cooperate with longitudinal adjustment and drive, longitudinal lifting ports 7 are opened on the outer sides of the middle lifting cover 42 and the outer lifting cover 43, and the outer sides of the inner lifting support cover 41, the middle lifting cover 42 and the outer lifting cover 43 have outwardly protruding internal threaded lifting blocks 8. The first electrically-controlled lifting component 44, the second electrically-controlled lifting component 45 and the third electrically-controlled lifting component 46 are all composed of an adjusting screw 9 and a control motor 10 for controlling the adjusting screw 9.

[0048] The longitudinal lifting opening 7 on the outside of the middle lifting cover 42 and the outer lifting cover 43, and the internal threaded lifting blocks 8 on the outside of the inner lifting support cover 41, the middle lifting cover 42 and the outer lifting cover 43, through the mutual cooperation of the adjusting screw rod 9 and the control motor 10 in the first, second and third electric control lifting components, enable the four-way carrier to be quickly adjusted according to the size of the cargo. The cooperation of the adjusting screw rod 9 and the control motor 10 can achieve precise control of the lifting cover, thereby adjusting the height and volume of the internal loading compartment. This design solves the problem that the four-way carrier cannot be quickly adjusted according to the size of the cargo when loading cargo, and improves the adaptability and functionality of the four-way carrier.

[0049] Specifically, the inner lifting support cover 41 is movably assembled with the middle lifting cover 42 by the inner thread lifting block 8 on the first electric control lifting assembly 44, the middle lifting cover 42 is movably assembled with the outer lifting cover 43 by the inner thread lifting block 8 on the second electric control lifting assembly 45, and the outer lifting cover 43 is movably assembled with the main frame 1 by the inner thread lifting block 8 on the third electric control lifting assembly 45. The cooperation of the adjusting screw 9 and the control motor 10 can transmit power between different lifting assemblies, thereby realizing synchronous or separate adjustment of the lifting cover. In this way, the height and volume of the internal loading compartment can be flexibly adjusted according to the size and shape of the goods, thereby improving loading efficiency and safety.

[0050] Therefore, the present application realizes the function of the four-way carrier being able to be quickly adjusted according to the size of the cargo by designing the longitudinal lifting openings and the internal thread lifting blocks on the outer side of the inner lifting cover and the outer lifting cover, and combining the adjusting screws and the control motors in the first, second and third electric control lifting components. This technical solution not only solves the problem that the four-way carrier cannot be quickly adjusted in the prior art, but also improves its adaptability and functionality, and has significant technical progress and innovation.

[0051] In order to cooperate with the lifting and lowering adjustment, the inner lifting support cover shell 41 is movably assembled with the middle lifting cover shell 42 by means of the internal thread lifting block 8 mounted on the first electric control lifting component 44, the middle lifting cover shell 42 is movably assembled with the outer lifting cover shell 43 by means of the internal thread lifting block 8 mounted on the second electric control lifting component 45, and the outer lifting cover shell 43 is movably assembled with the main frame 1 by means of the internal thread lifting block 8 mounted on the third electric control lifting component 46.

[0052] Through the cooperation of the internal thread lifting block 8 and the electric control lifting assembly, the movable connection between the inner lifting support cover 41, the middle lifting cover 42 and the outer lifting cover 43 is realized. The inner lifting support cover 41 is sleeved on the first electric control lifting assembly 44, so that it can be movably connected with the middle lifting cover 42; the middle lifting cover 42 is sleeved on the second electric control lifting assembly 45, so that it can be movably connected with the outer lifting cover 43; the outer lifting cover 43 is sleeved on the third electric control lifting assembly 46, so that it can be movably connected with the main frame 1. This design realizes the multi-layer liftable structure of the internal loading compartment through the coordinated work of multiple electric control lifting assemblies, and solves the problem of how to realize the movable assembly between the multi-layer structures of the electric control liftable internal loading compartment.

[0053] Specifically, the inner lifting support cover 41 is connected to the first electric lifting assembly 44 through the internal thread lifting block 8, and the first electric lifting assembly 44 can drive the inner lifting support cover 41 to move in the vertical direction. The middle lifting cover 42 is connected to the second electric lifting assembly 45 through the internal thread lifting block 8, and the second electric lifting assembly 45 can drive the middle lifting cover 42 to move in the vertical direction. The outer lifting cover 43 is connected to the third electric lifting assembly 46 through the internal thread lifting block, and the third electric lifting assembly 46 can drive the outer lifting cover 43 to move in the vertical direction. Through this design, the inner lifting support cover 41, the middle lifting cover 42 and the outer lifting cover 43 can be lifted and lowered relatively independently, thereby realizing the movable assembly between the multi-layer structure of the internal loading compartment.

[0054] Therefore, the present application realizes a multi-layer liftable structure of the internal loading compartment through the coordinated work of multiple electrically-controlled lifting components, effectively solving the problem in the prior art that the four-way vehicle has a fixed structure and cannot be quickly adjusted according to the size of the loaded cargo, thereby improving the adaptability and functionality of the four-way vehicle.

[0055] In order to cooperate with the bottom assembly and adjustment, a sunken assembly groove for assembling the electrically controlled rotating bottom control bracket 5 is opened at the bottom of the inner lifting support cover 41. The electrically controlled rotating bottom control bracket 5 includes a rotating adjustment ring 51 movably installed inside the sunken assembly groove, a rotating adjustment motor 52, an internal assembly frame 53 fixed on the inner arc surface of the rotating adjustment ring 51, a flip adjustment plate 54 movably installed on the inner arc surface of the rotating adjustment ring 51 and a control support rod 55 movably installed inside the internal assembly frame 53.

[0056] The sunken assembly groove at the bottom of the inner lifting support cover 41 is used to assemble the electric-controlled rotating bottom control bracket 5. The electric-controlled rotating bottom control bracket 5 realizes the rotation and adjustment of the goods through the cooperation of the rotating adjustment ring 51, the rotating adjustment motor 52, the internal assembly frame 53, the flip adjustment plate 54 and the control strut 55. The rotating adjustment ring 51 and the rotating adjustment motor 52 provide rotational power, the internal assembly frame 53 and the flip adjustment plate 54 are used to fix and adjust the position of the goods, and the control strut 55 ensures the stability of the goods during the adjustment process. Through the mutual cooperation of these technical features, the four-way carrier can quickly lift and separate the goods to the designated position when unloading, thereby improving the unloading efficiency.

[0057] Specifically, the rotating adjustment ring 51 can be driven by the rotating adjustment motor 52 to achieve the rotation adjustment of the internal assembly frame 53. A flip adjustment plate 54 is fixed on the inner arc surface of the internal assembly frame 53. By flipping and adjusting the flip adjustment plate 54, the precise adjustment of the position of the goods can be achieved. The control support rod 55 is used to provide necessary support and stability during the adjustment process to prevent the goods from tilting or moving during the adjustment process. As a preferred embodiment, the various components of the electrically controlled rotating bottom control bracket 5 can adopt a modular design to facilitate maintenance and replacement.

[0058] Therefore, the present application realizes the rapid rotation and position adjustment of the cargo by setting a sunken assembly groove at the bottom of the inner lifting support cover and assembling an electrically controlled rotating bottom control bracket therein. Compared with the prior art, the present application can not only make rapid adjustments according to the size of the cargo, thus improving the efficiency of loading and unloading, but also ensure the stability of the cargo during the adjustment process by controlling the setting of the support rod, thus enhancing the adaptability and functionality of the four-way carrier.

[0059] In order to improve external protection, an external protective cover 11 is fixedly mounted on the outer side of the main frame 1 at the periphery of the first electrically-controlled driving lifting wheel 2 and the second electrically-controlled driving lifting wheel 3 .

[0060] An external protective cover 11 is installed on the outside of the main frame 1, and the external protective cover 11 covers the periphery of the first electrically controlled driving lifting wheel 2 and the second electrically controlled driving lifting wheel 3. The function of the external protective cover 11 is to protect the driving lifting wheels from the influence of the external environment and accidental collisions, and to ensure the stability and safety of the driving wheels. By adding the external protective cover 11, the four-way carrier can effectively reduce the risk of damage when operating in a complex environment, and improve the overall protection capability of the equipment, thereby solving the problem of how to improve the safety and protection capability of the four-way carrier.

[0061] The outer protective cover 11 can be made of metal material or high-strength plastic material to ensure that it has sufficient strength and durability. The installation of the outer protective cover 11 can be carried out by bolting or welding to ensure that it is stable and not easy to fall off. Furthermore, the design of the outer protective cover 11 can take into account air circulation to prevent the driving lifting wheel from affecting performance due to poor heat dissipation during long-term operation. As a preferred embodiment, the surface of the outer protective cover 11 can be coated with an anti-rust coating to improve its corrosion resistance in a humid environment.

[0062] By installing an external protective cover 11 on the outside of the main frame 1, the driving lifting wheel is effectively protected from damage by the external environment, thereby improving the safety and protection capability of the four-way transport vehicle. Compared with the prior art, the present application significantly improves the adaptability and reliability of the device in a complex environment by adding an external protective cover 11, thereby solving the deficiencies of the existing four-way transport vehicles in terms of safety and protection capability.

[0063] In order to facilitate adjustment and assembly, both sides of the flip adjustment plate 54 are movably equipped with electrically controlled lateral clamping arms 12 .

[0064] The electrically controlled lateral clamping arms 12 on both sides of the flip adjustment plate 54 can provide lateral clamping force during cargo handling, thereby improving the stability of the cargo. This design realizes the control of the clamping arms by electronic control, and can make real-time adjustments according to the size and shape of the cargo, so that the cargo will not lose balance due to lateral shaking during handling.

[0065] The electric-controlled side clamping arm 12 may be implemented in the following ways: one possible implementation is to drive the clamping arm by a motor to clamp the cargo; another is to use a hydraulic or pneumatic system to control the action of the clamping arm to provide a stronger clamping force. In addition, the size and position of the cargo can be detected by a sensor to automatically adjust the clamping force and position of the clamping arm to ensure the stability of the cargo during transportation.

[0066] The electrically controlled lateral clamping arm design of the present application has significant advantages over the prior art. Specifically, by electrically controlling the clamping arm, it can be flexibly adjusted according to the characteristics of different goods, thereby improving the adaptability and stability of the four-way carrier when loading and transporting goods. Thus, the problem of the existing four-way carrier having a fixed structure and limited lateral limiting capacity is solved, thereby improving the functionality and practicality of the carrier.

[0067] In order to cooperate with the electrically controlled translational clamping, a strip-shaped adjustment opening 13 is symmetrically opened on the flip adjustment plate 54, and the electrically controlled lateral clamping arm 12 includes a horizontal adjustment screw 121 movably mounted on the inner wall of the flip adjustment plate 54, an internally threaded translation block 122 threadedly sleeved on the horizontal adjustment screw 121, and a lateral clamping arm 123 fixed on the side wall of the internally threaded translation block 122.

[0068] The lateral clamping arm 123 uses an electromagnetically controlled iron spring installed on the internal thread translation block 122 to control the flipping and storage or elastic extrusion and expansion.

[0069] The strip-shaped adjustment opening 13 symmetrically provided on the flip adjustment plate 54 enables the electric-controlled lateral clamping arm 12 to move flexibly. The horizontal adjustment screw 121, the internal thread translation block 122 and the lateral clamping arm 123 of the electric-controlled lateral clamping arm 12 cooperate with each other to realize the lateral clamping function by electric control. The horizontal adjustment screw 121 provides the translational force of the clamping arm, and the internal thread translation block 122 converts this force into a clamping action, and the lateral clamping arm 123 finally realizes the clamping of the goods.

[0070] The horizontal adjustment screw can be driven by a motor, which is connected to a control system. The control system can accurately control the rotation of the horizontal adjustment screw, thereby controlling the movement of the internal thread translation block. The movement of the internal thread translation block drives the lateral clamping arm to clamp or release. The design of the strip adjustment port enables the lateral clamping arm to adjust its position according to the size of the goods during the clamping process, ensuring the stability and reliability of the clamping.

[0071] Through the above technical solution, the present application can effectively solve the lateral clamping problem of the four-way carrier when loading goods, so that the four-way carrier can flexibly adjust the clamping position when loading goods of different sizes, thereby improving the stability and safety of loading. Compared with the prior art, the electric-controlled lateral clamping arm of the present application can realize automatic control, improve the convenience and efficiency of operation, and has stronger adaptability.

[0072] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description.
