Description

Technical Field

[0001] This utility model relates to the field of four-way shuttle vehicles, and in particular to a shell structure for a four-way shuttle vehicle and a four-way shuttle vehicle. Background Technology

[0002] In the field of logistics and warehousing automation, four-way shuttles, as a highly efficient material handling equipment, have been widely used and developed in recent years.

[0003] In the existing technology, the conventional approach for the shell structure of a four-way shuttle is to use an integral shell to completely enclose the vehicle body. This method can provide good protection for the vehicle body and prevent dust, debris and other objects from entering the vehicle body and affecting its normal operation.

[0004] However, these existing technologies have certain drawbacks. While a one-piece casing offers good protection, it is not conducive to heat dissipation. Prolonged use may lead to excessively high internal temperatures within the vehicle, affecting the lifespan and performance of the equipment.

[0005] In conclusion, how to design a four-way shuttle car shell structure that can effectively dissipate heat is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a shell structure for a four-way shuttle and a four-way shuttle, which effectively improves the heat dissipation effect of the shell structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A shell structure for a four-way shuttle vehicle, comprising: The frame is assembled onto the vehicle body; Top plate, fixedly covering the top plane of the frame; There are four corner side panels, and the four corner side panels are respectively located at the four corners of the frame. There is a gap between each corner side panel so that the side of the frame is exposed. The frame has a slide rail groove on its side, which is exposed on the vehicle body and communicates with the interior space of the vehicle body.

[0008] Preferably, the slide rail groove passes through both ends of the side of the frame and extends to the outside of the vehicle body.

[0009] Preferably, the back of the top plate is provided with a reinforcing member, and a connecting structure is provided between adjacent corner side plates.

[0010] Preferably, the top plate includes a central recess and two side supports.

[0011] Preferably, the edge portion of the top plate contacts the top structure of the corner side plate, and the top plate and the corner side plate together form a flush corner structure.

[0012] Preferably, each side of the corner side plate is formed with a mounting groove for accommodating a wheel.

[0013] Preferably, at least one of the mounting slots in each corner side plate is a waist-shaped hole to accommodate at least two of the wheels.

[0014] A four-way shuttle includes the aforementioned four-way shuttle housing structure and wheels disposed on the vehicle body.

[0015] Preferably, the axial end face of the wheel protrudes beyond the outer surface of the corner side plate, and the axial end face of the wheel is provided with a buffer assembly for the wheel to prevent collisions.

[0016] Preferably, the buffer assembly includes a buffer pad covering the axial end face of the wheel, the buffer pad being made of an elastic buffer material.

[0017] Preferably, the wheel surface of the axial end face of the wheel is provided with a continuously recessed annular damping groove, and the buffer pad is an annular buffer pad and is embedded in the annular damping groove; The elastic pad has a trapezoidal cross-section, with the lower base of the trapezoid embedded in the bottom of the annular shock-absorbing groove, and the upper base of the trapezoid protruding from the axial end face of the wheel.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: In the above technical solution, the corner side plates are set at the four corners of the frame and spaced apart from each other, so that the sides of the frame are exposed.

[0019] In the above technical solution, the wheel end face protrudes from the corner side plate and has a buffer component. In the event of a collision, the wheel will prevent impact, reduce damage to the shell, and lower maintenance costs.

[0020] In the above technical solution, the combination of reinforcing and connecting structures effectively improves the torsional deformation resistance of the top plate and effectively ensures the stability of the overall dimensions. Attached Figure Description

[0030] The core of this utility model is to provide a shell structure for a four-way shuttle vehicle.

[0031] Another core aspect of this utility model is to provide a four-way shuttle vehicle, including the aforementioned four-way shuttle vehicle shell structure.

[0032] like Figure 1 A specific embodiment of the shell structure for the four-way shuttle vehicle shown includes a frame 4, a top plate 2, and corner side plates 3. The frame 4 is assembled on the vehicle body 1. The top plate 2 is fixedly covered on the top plane of the frame 4. There are four corner side plates 3, and the four corner side plates 3 are respectively located at the four corners of the frame 4. There is a gap between each corner side plate 3 so that the side of the frame 4 is exposed. The side of the frame 4 is provided with a slide rail groove, which is exposed on the vehicle body 1 and communicates with the internal space of the vehicle body 1.

[0033] Specifically, frame 4 is assembled onto vehicle body 1, top plate 2 is fixedly covered on the top plane of frame 4, and four corner side plates 3 are respectively located at the four corners of frame 4. There are gaps between the corner side plates 3, allowing the sides of frame 4 to be exposed. The sides of frame 4 are provided with slide rail grooves, which are exposed on vehicle body 1 and communicate with the interior space of vehicle body 1, achieving the effect of both protecting the internal components of vehicle body and facilitating heat dissipation. Since the corner side plates 3 do not enclose the sides of frame 4, the air circulation space is increased, and the communication between the slide rail grooves and the interior of vehicle body 1 also promotes heat dissipation.

[0034] It should be noted that frame 4 is the fundamental supporting component of the entire shell structure. Frame 4 can be made of metal, such as aluminum alloy, which is lightweight and high-strength. The shape of frame 4 can be rectangular, with a robust and stable structure, providing a reliable mounting base for the top plate 2 and corner side plates 3. Frame 4 can also be made of steel, which has greater strength and is suitable for scenarios with higher structural strength requirements. When frame 4 is assembled onto the vehicle body 1, it can be connected by bolts, which is convenient for installation and disassembly, and also facilitates later maintenance and repair; alternatively, it can be welded, which makes the connection between frame 4 and vehicle body 1 more secure, ensuring the stability of the overall structure.

[0035] The aforementioned four-way shuttle car shell structure, through the rational combination of frame 4, top plate 2, and corner side plates 3, not only ensures the protection of the internal components of the car body 1, but also significantly improves heat dissipation performance through the spacing between the corner side plates 3 and the design of the sliding rail grooves. Compared with the traditional one-piece enclosed shell, it reduces the impact of heat accumulation on the performance and lifespan of the internal components of the car body. At the same time, this structural design is simple and reasonable, and is relatively convenient for installation and maintenance, reducing operating and maintenance costs, and making a significant improvement and contribution to existing technology.

[0036] Based on any of the above embodiments, the slide rail groove penetrates both ends of the side of the frame 4 and extends to the outside of the vehicle body 1. The slide rail groove can be integrally formed on the frame using a casting process, which can ensure the structural strength and precision of the slide rail groove. The slide rail groove not only serves to guide sliding but also communicates with the internal space of the vehicle body 1, acting as a heat dissipation channel. When heat accumulates inside the vehicle body 1, hot air can be exhausted through the slide rail groove, and cold air from the outside can also enter the vehicle body 1 through the slide rail groove, forming air convection, thereby effectively reducing the temperature inside the vehicle body. Therefore, the slide rail groove penetrating both ends of the side of the frame and extending to the outside of the vehicle body not only exposes the side of the frame but also allows the slide rail groove to better communicate with the internal space of the vehicle body, enhancing the heat dissipation effect.

[0037] Based on any of the above embodiments, please refer to Figure 5 The top plate 2 has a reinforcing member 7 on its back side, and a connecting structure is provided between adjacent corner side plates 3. The reinforcing member 7 is a rectangular structure with an opening on one side, and it is fixed to the top plate 2 by spot welding.

[0038] Optionally, the connecting structure includes a first connecting member 81 and a second connecting member 82, such as... Figure 3 As shown, a first connector 81 is provided between the two corner side plates 3 on the upper and lower sides of the top plate 2. The first connector 81 is integrally bent into shape with the side of the top plate 2. A second connector 82 is provided between the two corner side plates 3 on the left and right sides of the top plate 2. The second connector 82 is bolted to the two corner side plates 3. Through the provided reinforcement 7, the first connector 81 and the second connector 82, the overall torsional deformation resistance of the shell structure is effectively enhanced, ensuring the dimensional stability of the overall shape.

[0039] Based on any of the above embodiments, please refer to Figure 2 and Figure 5The top plate 2 includes a central recessed portion and two side support portions. When a pallet is placed on the top plate 2, the pallet carries an object to be transported. Since the object to be transported has a certain weight, and the pallet only has support feet on both sides, the pallet will have a central recess. Therefore, the central part of the top plate 2 is designed as a recessed structure to better fit the pallet and avoid excessive load on the pallet by the top plate 2.

[0040] Based on any of the above embodiments, please refer to Figure 2 and Figure 3 The edge of the top plate 2 is in contact with the top structure of the corner side plate 3, and the top plate 2 and the corner side plate 3 together form a flush top corner structure.

[0041] Specifically, the edge of the top plate 2 contacts the top structure of the corner side plate 3, forming a flush corner structure, making the entire shell structure more regular and aesthetically pleasing, while also enhancing structural stability. The top plate 2 can be made of plastic, which is lightweight, low-cost, and has some corrosion resistance; alternatively, it can be made of composite materials, which have better strength and rigidity, providing better protection for the internal components of the vehicle body 1. The top plate 2 is bolted to the frame 4, ensuring a secure installation and facilitating replacement and adjustment.

[0042] In other embodiments, the corner side panel 3 can also be installed using a snap-fit ​​connection. Snap-fit ​​connections offer the advantages of quick and convenient installation, allowing for rapid disassembly and reassembly when the corner side panel 3 needs to be replaced. The corner side panel 3 can also be made of fiberglass, which is lightweight, high-strength, and corrosion-resistant, further improving the performance of the shell structure. By changing the installation method and material of the corner side panel 3, installation efficiency and shell performance are improved while ensuring the basic functions of the shell structure. Snap-fit ​​connections save installation time and improve production efficiency; fiberglass corner side panels better adapt to different working environments, extending the service life of the shell structure, thus representing an improvement and contribution to existing technology.

[0043] Based on any of the above embodiments, refer to Figures 2 to 5 Each side of the corner side plate 3 has a mounting groove 31 for accommodating the wheel 5. Specifically, the mounting groove 31 effectively facilitates the installation of the wheel 5, thereby avoiding affecting the normal operation of the four-way shuttle. Except for the bottom, the mounting groove 31 has an arc-shaped structure, which can better adapt to the structure of the wheel 5.

[0044] Optionally, at least one mounting slot 31 in each corner side plate 3 is a waist-shaped hole to accommodate at least two wheels 5.

[0045] Specifically, the four-way shuttle includes a daughter wheel assembly and a mother wheel assembly. The mother wheel assembly usually has only one mother wheel in the same position, while the daughter wheel assembly usually has two daughter wheels arranged in sequence in the same position. By setting the mounting groove 31 as an oblong hole structure, it can better fit the structure of the two daughter wheels. Of course, if the mother wheel also adopts a structure of two arranged in sequence, the mounting groove at the mother wheel can also be set as an oblong hole structure.

[0046] The implementation principle of this embodiment is as follows: The four-way shuttle car shell structure of this embodiment, through the reasonable combination of frame 4, top plate 2, and corner side plates 3, not only ensures the protection of the internal components of the car body, but also greatly improves heat dissipation performance through the spacing between the corner side plates 3 and the design of the sliding rail grooves. Compared with the traditional integral closed shell, it reduces the impact of heat accumulation on the performance and lifespan of the internal components of the car body. At the same time, this structural design is simple and reasonable, and is relatively convenient for installation and maintenance, reducing the cost of use and maintenance, and making a significant improvement and contribution to the existing technology.

[0047] This application further discloses a four-way shuttle vehicle, including the aforementioned four-way shuttle vehicle shell structure and wheels 5 disposed on the vehicle body 1.

[0048] like Figure 1 As shown, the axial end face of the wheel 5 protrudes from the outer surface of the corner side plate 3, and the axial end face of the wheel 5 is provided with a buffer assembly, which is used to prevent the wheel 5 from being hit.

[0049] Specifically, the axial end face of the wheel 5 protrudes from the outer surface of the corner side plate 3, and the axial end face of the wheel 5 is provided with a buffer assembly for the wheel 5 to prevent collisions. This ensures that in the event of a collision, the wheel 5 comes into contact with the external object first, and the buffer assembly on the wheel 5 absorbs the collision energy, rather than letting the corner side plate 3 or other parts bear the collision force, thereby reducing the degree of damage to the shell structure and reducing maintenance costs.

[0050] A specific implementation of the above-mentioned buffer component is described in reference to... Figure 1 The buffer assembly includes a buffer pad 6 covering the axial end face of the wheel 5, and the buffer pad 6 is made of elastic buffer material.

[0051] Specifically, a buffer pad 6 is provided on the axial end face of the wheel 5 near its outer side. The buffer pad 6 can be detachably connected to the axial end face of the wheel 5 by bolts. The buffer pad 6 is made of an elastic buffer material, such as sponge rubber, which has good elasticity and buffering performance and can effectively absorb collision energy. The buffer pad 6 can also be made of silicone, which has advantages such as high temperature resistance and aging resistance, ensuring that the buffer pad 6 can work normally in different working environments.

[0052] In one modified embodiment of the above-mentioned buffer pad 6, the wheel surface of the axial end face of the wheel 5 is provided with a continuously recessed annular damping groove, the buffer pad 6 is an annular buffer pad and is embedded in the annular damping groove; the cross-section of the elastic pad 6 is trapezoidal, and the lower base of the trapezoid is embedded in the bottom of the annular damping groove, and the upper base of the trapezoid protrudes from the axial end face of the wheel 5.

[0053] Specifically, an annular damping groove (not shown in the figure) is formed along the axis of wheel 5 on the axial end face near the outer side of wheel 5. The buffer pad 6 is annular with a trapezoidal cross-section and is embedded in the annular damping groove. The upper bottom surface of the buffer pad 6 protrudes from the axial end face of wheel 5 to provide lateral buffering for the four-way shuttle. The lower bottom surface of the buffer pad 6 is embedded in the bottom of the annular damping groove and is interference-fitted with the inner wall of the groove bottom, thereby effectively improving the installation strength of the buffer pad 6. This makes the connection between the buffer pad 6 and wheel 5 more secure and allows for better buffering performance.

[0054] The implementation principle of this embodiment is as follows: The four-way shuttle vehicle in this embodiment sets the anti-collision function on the wheels 5 and uses the buffer components on the wheels 5 to absorb collision energy, avoiding the large damage to the shell structure caused by collisions in traditional designs and reducing maintenance costs. At the same time, the reasonable design of the wheels 5 and the buffer components ensures the normal operation and anti-collision performance of the vehicle, which has significant improvements and contributions to the existing technology.

[0055] 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.
