Abstract
Description
Technical Field
[0001] This utility model relates to the field of semi-trailer technology, and in particular to a 10-foot container-specific transport semi-trailer and a mobile energy storage system. Background Technology
[0002] Currently, container semi-trailers can be used to transport 20-foot, 30-foot, 40-foot, or 45-foot containers, but there are no semi-trailers specifically designed for transporting 10-foot containers.
[0003] In addition, energy storage containers have a lot of electrical equipment installed inside, which requires high shock absorption performance during transportation. Conventional container semi-trailers cannot meet the shock absorption requirements for long-term mobile transportation of energy storage containers. Utility Model Content
[0004] One objective of this utility model is to overcome the shortcomings of existing technologies and provide a dedicated 10-foot container transport semi-trailer. To solve the aforementioned technical problems, this utility model adopts the following technical solution:
[0005] A 10-foot container-specific semi-trailer includes:
[0006] The main frame is designed to carry 10-foot containers;
[0007] Four locking devices are installed at the four corner pieces of the main frame corresponding to the bottom of a 10-foot container;
[0008] The connecting body is connected to the rear end of the frame body, and the front end of the connecting body is provided with a towing pin for connecting to the tractor. The top surface of the frame body is lower than the top surface of the connecting body.
[0009] The wheel assembly is located at the bottom of the frame body and near the rear end of the frame body. The distance from the rotation axis of the wheel assembly to the traction pin is greater than or equal to 4200mm, and the distance from the rear end face of the frame body to the front end face of the connecting body is less than or equal to 5600mm.
[0010] In one embodiment, the frame body includes two longitudinal beams and two transverse beams. The two longitudinal beams are arranged parallel to each other and are spaced apart and both extend in the front-rear direction. The two transverse beams are arranged parallel to each other and are spaced apart and both are perpendicularly connected to the two longitudinal beams.
[0011] The four locking devices are set in pairs on the two crossbeams. The two locking devices on the same crossbeam are separated by a distance equal to the distance between two corner pieces in the width direction of the bottom of the 10-foot container. The two locking devices on the same side of the two crossbeams are separated by a distance equal to the distance between two corner pieces in the length direction of the bottom of the 10-foot container.
[0012] In one embodiment, the two longitudinal beams are spaced less than 10 feet apart from each other, which is less than the standard width of a container.
[0013] In one embodiment, the two crossbeams are spaced apart from each other by a distance equal to the standard length of a 10-foot container; and / or
[0014] The length of each beam is equal to the standard width of a 10-foot container.
[0015] In one embodiment, the distance from the front end face of the connecting body to the traction pin is less than or equal to 500 mm; and / or
[0016] The distance from the traction pin to the front end face of the frame body is less than or equal to 1900mm.
[0017] In one embodiment, the diameter of the wheels in the wheel set is less than or equal to 1000 mm, and the distance from the top surface of the frame body to the lowest point of the wheel set is less than or equal to 1100 mm.
[0018] In one embodiment, an air suspension is provided between the frame body and the wheel assembly, and the wheel assembly is connected to the frame body via the air suspension.
[0019] In one embodiment, the locking device is a threaded lock that passes through the top surface of the frame body and is detachably connected to the corner fittings so that the bottom surface of the 10-foot container is in close contact with and fixed to the top surface of the frame body.
[0020] In one embodiment, the semi-trailer further includes:
[0021] Telescopic outriggers are installed at the connection between the frame body and the connecting body, and extend downwards.
[0022] The anti-collision structure is located at the rear end of the main frame and protrudes from the rear end face of the main frame.
[0023] In one embodiment, the semi-trailer further includes:
[0024] The toolbox is located on one side of the bottom of the frame body and near the front end of the frame body;
[0025] Firefighting components are located at the bottom of the chassis body and on the opposite side of the toolbox;
[0026] The spare tire assembly is located at the bottom of the chassis body, between the toolbox and the fire-fighting assembly.
[0027] Another objective of this utility model is to provide a mobile energy storage system, including an energy storage container and a semi-trailer as described in any of the above, wherein the energy storage container is adapted to be installed on the frame body.
[0028] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:
[0029] This utility model discloses a 10-foot container-specific semi-trailer comprising a frame body, four locking devices, a connecting body, and wheel sets. The frame body carries the 10-foot container, and the four locking devices are located at the four corner pieces corresponding to the bottom of the 10-foot container on the frame body for connecting and securing the container. The rear end of the connecting body is connected to the frame body, and its front end is equipped with a towing pin for connecting to a tractor unit. Thus, the semi-trailer's frame body can stably support and secure a single 10-foot container, and the towing pin connecting the connecting body to the tractor unit enables the movement of the semi-trailer, thereby facilitating the transport of a single 10-foot container.
[0030] Furthermore, the top surface of the main frame is lower than the top surface of the connecting body, which effectively reduces the height of the load-bearing surface of the main frame, lowers the center of gravity and overall height of the semi-trailer, improves the stability and passability of the semi-trailer during driving, reduces the amplitude of road bumps on the 10-foot container, and improves the transportation safety of the 10-foot container.
[0031] Furthermore, the wheel assembly is located at the bottom of the main frame body and near the rear end of the frame body. The distance from the wheel assembly's rotation axis to the towing pin is greater than or equal to 4200mm, and the distance from the rear end face of the main frame body to the front end face of the connecting body is less than or equal to 5600mm. By rationally setting the wheelbase and overall length of the semi-trailer, the total length of the semi-trailer can be kept relatively short to stably carry a 10-foot container while ensuring the semi-trailer's turning flexibility and driving stability.

[0045] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.
[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0048] Please see Figure 1 and Figure 2 As shown, the 10-foot container-specific semi-trailer 100 (hereinafter referred to as the semi-trailer) according to an embodiment of the present utility model includes a frame body 110 and four locking devices 120, as well as a connecting body 130 and a wheel set 140.
[0049] For ease of description and understanding, it is hereby stipulated that the direction of travel of the semi-trailer 100 is the front-to-back direction, the horizontal direction perpendicular to the front-to-back direction is the left-to-right direction, and the vertical direction perpendicular to the front-to-back direction is the up-to-down direction.
[0050] The chassis body 110 is configured to carry a 10-foot container 200, and the top surface of the chassis body 110 forms a bearing surface for contacting the bottom of the 10-foot container 200. The 10-foot container 200 may be an energy storage container.
[0051] For example, such as Figure 2 As shown, the frame body 110 includes two longitudinal beams 111, which are arranged parallel to each other and extend in the longitudinal direction. Optionally, the two longitudinal beams 111 are arranged such that the distance between them is less than the standard width of a 10-foot container 200.
[0052] It should be noted that the external dimensions of the existing 10-foot container 200 are approximately: 10 feet long (about 3.05 meters), 8 feet wide (about 2.05 meters), and 8 feet 6 inches high (about 2.59 meters). In this invention, all definitions corresponding to the standard length of the 10-foot container 200 should be understood as the length dimension of the aforementioned external dimensions of the 10-foot container 200; all definitions corresponding to the standard width of the 10-foot container 200 should be understood as the width dimension of the aforementioned external dimensions of the 10-foot container 200.
[0053] In this embodiment, the small distance between the two longitudinal beams 111 facilitates the arrangement of the wheel assembly 140 and avoids interference between the longitudinal beams 111 and the wheels. Furthermore, the small distance between the two longitudinal beams 111 helps lower the vehicle's center of gravity and improves the driving stability of the semi-trailer 100.
[0054] Optionally, the length of each longitudinal beam 111 is greater than the standard length of a 10-foot container 200. This ensures that the two end frames at the front and rear of the 10-foot container 200 can be supported at both ends of the longitudinal beam 111, respectively.
[0055] like Figure 2 As shown, the frame body 110 also includes two crossbeams 112, which are arranged parallel to each other and perpendicularly connected to two longitudinal beams 111. That is, both crossbeams 112 extend in the left-right direction. The top surfaces of the two crossbeams 112 and the top surfaces of the two longitudinal beams 111 constitute the top surface of the frame body 110.
[0056] For example, such as Figure 3As shown, the two crossbeams 112 can be arranged to be a distance between each other equal to the standard length of a 10-foot container 200. It is worth noting that "equal to" here does not mean absolutely equal, but should be understood as approximately equal to, for example, equal to or slightly greater than.
[0057] Specifically, the distance between the two crossbeams 112 is based on the sides of the two crossbeams 112 that are facing away from each other. (Reference) Figure 3 As shown, of the two crossbeams 112, one crossbeam 112 is located at the front end of the longitudinal beam 111, and the other crossbeam 112 is located at the rear end of the longitudinal beam 111. The distance between them can be L1, which is the distance from the front side of the front crossbeam 112 to the rear side of the rear crossbeam 112. Since the distance L1 between the two crossbeams 112 is approximately equal to the standard length of a 10-foot container 200, when the 10-foot container 200 is fixedly mounted on the frame body 110, the front face of the 10-foot container 200 does not extend beyond the front side of the front crossbeam 112; for example, the front face of the 10-foot container 200 can be substantially flush with the front side of the front crossbeam 112. The rear face of the 10-foot container 200 does not extend beyond the rear side of the rear crossbeam 112; for example, the two can be substantially flush. This allows the frame body 110 to support the 10-foot container 200 more stably.
[0058] It is understandable that the length of the longitudinal beam 111 is designed to be greater than the standard length of a 10-foot container 200, which is also greater than the distance L1 between the two crossbeams 112. Therefore, when the crossbeams 112 are connected to the longitudinal beam 111, the rear side of the crossbeam 112 located at the rear end of the longitudinal beam 111 can be flush with the rear end face of the longitudinal beam 111. The front end of the longitudinal beam 111 can protrude forward beyond the front side of the front crossbeam 112.
[0059] Optionally, such as Figure 2 As shown, the frame body 110 also includes multiple diagonal braces 113, with each diagonal brace 113 connected at both ends to the longitudinal beam 111 and the cross beam 112, respectively. The multiple diagonal braces 113 can enhance the connection strength between the longitudinal beam 111 and the cross beam 112, thereby strengthening the overall structural strength of the frame body 110 and improving the support strength of the frame body 110.
[0060] See Figure 3 In one embodiment, the length L2 of each beam 112 is equal to the standard width of a 10-foot container 200. It is worth noting that "equal to" here does not mean absolutely equal, but should be understood as approximately equal to, for example, equal to or slightly greater than.
[0061] When the 10-foot container 200 is fixedly mounted on the chassis body 110, the left end face of the 10-foot container 200 does not extend beyond the left end face of each crossbeam 112; for example, the left end face of the 10-foot container 200 is substantially flush with the left end face of each crossbeam 112. The right end face of the 10-foot container 200 does not extend beyond the right end face of each crossbeam 112; for example, the two are substantially flush.
[0062] In this embodiment of the present invention, by setting the length and spacing of the two crossbeams 112 of the frame body 110, it can be ensured that the two crossbeams 112 can be correspondingly set with the bottom of the two end frames of the 10-foot container 200, so as to better support and fix the 10-foot container 200, and ensure that the 10-foot container 200 does not exceed the frame body 110 in the front-back and left-right directions, so that the frame body 110 can protect the 10-foot container 200 to a certain extent.
[0063] See Figure 2 As shown, in an embodiment of this utility model, four locking devices 120 are disposed at the positions of the four corner pieces of the frame body 110 corresponding to the bottom of the 10-foot container 200.
[0064] For example, four locking devices 120 are arranged in pairs on two crossbeams 112. Two locking devices 120 on the same crossbeam 112 can be positioned at the left and right ends of the crossbeam 112, respectively, with a distance between them equal to the distance between two corner pieces along the width of the bottom of a 10-foot container 200. On the front and rear crossbeams 112, two locking devices 120 on the same side can be a distance between them equal to the distance between two corner pieces along the length of the bottom of a 10-foot container 200.
[0065] In this embodiment, by setting each locking device 120 to correspond to each corner piece, and by detachably connecting the locking device 120 to the corner piece, a reliable fixation of the 10-foot container 200 can be achieved.
[0066] In one embodiment, the locking device 120 is a threaded lock that passes through the top surface of the chassis body 110 and is detachably connected to the corner fittings, so that the bottom surface of the 10-foot container 200 is in close contact with and fixed to the top surface of the chassis body 110. In this embodiment, by using a threaded lock, it can tighten the corner fittings and prevent loosening when connected to them, thereby eliminating the gap between the top surface of the chassis body 110 and the corner fittings, effectively preventing relative jumping between the 10-foot container 200 and the semi-trailer 100 during operation, and reducing the vibration amplitude of the 10-foot container 200 during transportation.
[0067] It is understood that in other embodiments, the locking device 120 may also adopt other locking structures, as long as it can reliably connect the corner pieces so that the 10-foot container 200 can be tightly fitted and fixed to the top surface of the frame body 110.
[0068] See Figure 2 and Figure 4 As shown, in an embodiment of this utility model, the rear end of the connecting body 130 is connected to the frame body 110, and the front end of the connecting body 130 is provided with a towing pin 131 for connection with a tractor. For example, the connecting body 130 may include two parallel, spaced-apart connecting beams, both extending in the front-rear direction. The two connecting beams may be arranged in a one-to-one correspondence with two longitudinal beams 111, and the rear end of each connecting beam is respectively connected and fixed to the front end of the corresponding longitudinal beam 111.
[0069] A towing seat can be provided at the front end of the two connecting beams, and a towing pin 131 is provided on the towing seat. The connecting body 130 can be connected to the tractor vehicle through the towing pin 131, so that the tractor vehicle can drive the frame body 110 and the 10-foot container 200 to move through the connecting body 130.
[0070] See Figure 2 and Figure 5 Optionally, the top surface of the frame body 110 is lower than the top surface of the connecting body 130. That is, as... Figure 5 As shown, viewed from the front and rear direction, the frame body 110 is lowered relative to the connecting body 130, thereby effectively reducing the height of the load-bearing surface of the frame body 110, lowering the center of gravity and overall height of the semi-trailer 100, improving the stability and passability of the semi-trailer 100 during driving, reducing the amplitude of road bumps on the 10-foot container 200, and improving the transportation safety of the 10-foot container.
[0071] See Figure 2 In one embodiment, the semi-trailer 100 includes telescopic outriggers 160, which are disposed at the connection between the frame body 110 and the connecting body 130, and extend downward. Specifically, the top end of the telescopic outrigger 160 can be connected to the front end of the frame body 110 and the rear end of the connecting body 130. The bottom end of the telescopic outrigger 160 extends downward to abut against the road surface, thereby supporting the frame body 110 and the connecting body 130, improving the connection strength between the frame body 110 and the connecting body 130, and enhancing the load-bearing capacity of the semi-trailer 100. When the semi-trailer 100 is in motion, the bottom end of the telescopic outrigger 160 can retract upward, allowing the tractor to move the connecting body 130, the frame body 110, and the container, thus realizing the container transportation function.
[0072] The telescopic outrigger 160 may adopt the telescopic outrigger structure in related technologies, and this application does not make specific limitations on it.
[0073] See Figure 2 As shown, in an embodiment of this utility model, the wheel assembly 140 is disposed at the bottom of the frame body 110 and near the rear end of the frame body 110. Figure 4 As shown, this utility model can be provided with a set of wheel groups 140, which can include four wheels, with the four wheels arranged in pairs on the left and right sides of the frame body 110.
[0074] Optionally, the diameter of the wheels in the wheel set 140 can be less than or equal to 1000 mm, so as to reduce the height of the load-bearing surface of the frame body 110, thereby reducing the center of gravity and overall height of the semi-trailer 100.
[0075] Optionally, the wheels in the wheel set 140 can be radial tires, which have advantages such as high load-bearing capacity and good shock absorption performance, thereby helping to improve the driving stability of the semi-trailer 100.
[0076] like Figure 5 As shown, in one embodiment, the distance L3 from the top surface of the frame body 110 to the lowest point of the wheel assembly 140 can be less than or equal to 1100mm. That is, the height of the load-bearing surface of the frame body 110 is less than or equal to 1100mm. By reasonably setting the height of the load-bearing surface, the center of gravity and overall height of the semi-trailer 100 can be effectively reduced, thereby improving the stability and passability of the semi-trailer 100.
[0077] like Figure 5 As shown, in one embodiment, the distance L4 from the rotation axis of the wheel assembly 140 to the towing pin 131 can be greater than or equal to 4200 mm. The distance L5 from the rear end face of the frame body 110 to the front end face of the connecting body 130 can be less than or equal to 5600 mm. By reasonably setting the wheelbase L4 and the overall length L5 of the semi-trailer 100, the total length of the semi-trailer 100 can be shortened to be suitable for stably carrying a 10-foot container 200, while ensuring the turning flexibility and driving stability of the semi-trailer 100.
[0078] like Figure 5 As shown, in one embodiment, the distance L6 from the front end face of the connecting body 130 to the towing pin 131 can be less than or equal to 500 mm. The distance L7 from the towing pin 131 to the front end face of the frame body 110 can be less than or equal to 1900 mm. By reasonably setting the front overhang L6 and the rear turning radius L7 of the semi-trailer 100, the axle load distribution of the semi-trailer 100 can be made more reasonable, which is conducive to reducing the overall length of the semi-trailer 100 and shortening the turning radius of the semi-trailer 100.
[0079] like Figure 2 As shown, in one embodiment, the semi-trailer 100 includes a crash barrier 170, which is disposed at the rear end of the frame body 110 and protrudes from the rear end face of the frame body 110. For example, the crash barrier 170 may include a crash barrier bracket 171, the top of which may be connected to the rear side of the crossbeam 112 at the rear end of the frame body 110. Further, a crash barrier plate 172 may protrude from the rear side of the top of the crash barrier bracket 171 to increase the crash distance.
[0080] It is worth noting that the distance L5 from the rear end face of the main frame 110 to the front end face of the connecting body 130, i.e., the total length of the semi-trailer 100, should be understood to include the anti-collision structure 170. In other words, the total length of the semi-trailer 100 can be the distance L5 from the front end face of the connecting body 130 to the rear end face of the anti-collision structure 170, and this distance L5 can be less than or equal to 5600mm.
[0081] See Figure 4 As shown, in one embodiment, an air suspension 150 is provided between the frame body 110 and the wheel assembly 140, and the wheel assembly 140 is connected to the frame body 110 through the air suspension 150. The air suspension 150 may employ an air suspension structure from the related art, and this application does not specifically limit its application to this type.
[0082] In this embodiment, by setting the air suspension 150 connecting group and the frame body 110, the shock absorption performance of the wheel group 140 and the frame body 110 can be effectively improved, thereby improving the overall shock absorption performance of the semi-trailer 100 during driving, enabling the semi-trailer 100 to adapt to driving under harsh road conditions, and effectively reducing the damage of vehicle body vibration to the semi-trailer 100 and the container under harsh road conditions.
[0083] like Figure 4 As shown, in one embodiment, the semi-trailer 100 also includes a toolbox 180, which is located on one side of the bottom of the frame body 110 and near the front end of the frame body 110. By providing the toolbox 180, it can be used to store tools, parts, etc., which can help deal with emergencies and ensure the normal use of the semi-trailer 100.
[0084] like Figure 4 As shown, in one embodiment, the semi-trailer 100 further includes a fire-fighting component 181, which is disposed at the bottom of the frame body 110 and located on the opposite side of the toolbox 180. The fire-fighting component 181 can be a fire extinguisher container. By providing the fire-fighting component 181, the safety of the semi-trailer 100 can be increased. Positioning the fire-fighting component 181 at the bottom of the frame body 110 and on the opposite side of the toolbox 180 helps to balance the weight on both sides of the frame body 110, improving the stability of the semi-trailer 100.
[0085] like Figure 4 As shown, in one embodiment, the semi-trailer 100 further includes a spare tire assembly 182, which is disposed at the bottom of the frame body 110 and located between the toolbox 180 and the fire-fighting assembly 181. The spare tire assembly 182 may include a spare tire holder and a spare tire, with the spare tire fixedly mounted on the spare tire holder. The spare tire holder may be welded to the frame body 110. By providing the spare tire assembly 182, it is possible to respond to emergencies and ensure the normal operation of the semi-trailer 100. By arranging the spare tire assembly 182 at the bottom of the frame body 110 and between the toolbox 180 and the fire-fighting assembly 181, the weight of the frame body 110 can be balanced, improving the stability of the semi-trailer 100.
[0086] See Figure 1 This utility model also provides a mobile energy storage system, including an energy storage container and a semi-trailer of any of the above embodiments. The energy storage container can be a 10-foot container, and its interior houses battery modules and a control system. The energy storage container is adapted to be mounted on the vehicle frame body 110. For example, the bottom of the energy storage container has four corner pieces corresponding to four locking devices 120. Through the corresponding connection of each corner piece to each locking device 120, the energy storage container can be reliably fixed to the vehicle frame body 110.
[0087] The 10-foot container-specific semi-trailer implemented in this utility model can not only meet the transportation function of a single 10-foot container, but also meet the shock absorption requirements of energy storage containers for mobile transportation, filling the gap in 10-foot container transport vehicles.
[0088] This utility model discloses a 10-foot container-specific semi-trailer, comprising a frame body, four locking devices, a connecting body, and wheel sets. The frame body carries the 10-foot container, and the four locking devices are located at the four corner pieces corresponding to the bottom of the 10-foot container on the frame body for connecting and securing the container. The rear end of the connecting body is connected to the frame body, and its front end has a towing pin for connecting to a tractor unit. Thus, the semi-trailer's frame body can stably support and secure a single 10-foot container, and the towing pin connecting the connecting body to the tractor unit enables the movement of the semi-trailer, thereby facilitating the transport of a single 10-foot container.
[0089] Furthermore, the top surface of the main frame is lower than the top surface of the connecting body, which effectively reduces the height of the load-bearing surface of the main frame, lowers the center of gravity and overall height of the semi-trailer, improves the stability and passability of the semi-trailer during driving, reduces the amplitude of road bumps on the 10-foot container, and improves the transportation safety of the 10-foot container.
[0090] Furthermore, the wheel assembly is located at the bottom of the main frame body and near the rear end of the frame body. The distance from the wheel assembly's rotation axis to the towing pin is greater than or equal to 4200mm, and the distance from the rear end face of the main frame body to the front end face of the connecting body is less than or equal to 5600mm. By rationally setting the wheelbase and overall length of the semi-trailer, the total length of the semi-trailer can be kept relatively short, making it suitable for stably carrying 10-foot containers while ensuring the semi-trailer's turning flexibility and driving stability, thus improving the transportation safety of 10-foot containers.
[0091] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.
[0092] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
