Description

Technical Field

[0001] This utility model relates generally to the technical field of container structures, and more specifically to a frame system and a container. Background Technology

[0002] In today's fiercely competitive global supply chain efficiency landscape, promoting swap body containers has become a strategic choice for overcoming logistics bottlenecks. Traditional containers frequently encounter pain points in multimodal transport involving road, rail, and water, such as time-consuming loading and unloading and rigid equipment scheduling. Statistics show that the average time spent by goods in transit is as high as 30%. However, by adopting standardized swap body containers, through rapid separation technology between the chassis and the container, full container transshipment can be completed in 15 minutes at railway stations, increasing port handling efficiency by more than 40% and significantly reducing cargo transit time. Its modular design is more compatible with the European "mobile warehouse" model, allowing the same container to seamlessly switch between road trucks, railway flatcars, and inland waterway barges, reducing the empty-running rate of traditional trucks by approximately 25%. Driven by carbon neutrality goals, the lightweight alloy frame of swap body containers is 18% lighter than traditional steel containers, saving an average of 1200 liters of fuel per container per year, aligning with the trend of green logistics development. Faced with the explosive growth of cross-border e-commerce and the time-sensitive demands of emergency logistics, promoting this type of efficient vehicle has irreplaceable value in building resilient supply chains.

[0003] In actual use of exchange container, the limited height of the vehicle chassis and space make it extremely inconvenient for operators to operate the opening and closing of the support legs of the exchange container's base frame. For this reason, the exchange container is difficult to promote and apply in some areas.

[0004] Therefore, there is a need to provide a chassis system and container to at least partially solve the above problems. Utility Model Content

[0129] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0130] This utility model provides a chassis system.

[0131] Please see Figures 1 to 6 The base frame system 120 includes a base frame 130 and a support member 141 (see...). Figure 5 ), locking component 150 (see Figure 4 and Figure 6 ) and drive component 160 (see Figure 5 Specifically, support member 141 is movably connected to base frame 130 between a supported position and a retracted position. Locking member 150 is movably connected to support member 141 between a locked position and an unlocked position. Drive assembly 160 is disposed on base frame 130 (see...). Figure 2 and Figure 5The drive assembly 160 and the locking member 150 are configured in a one-to-one correspondence. The drive assembly 160 is used to drive the locking member 150 to move between a locked position and an unlocked position. The drive assembly 160 includes a link 161 and an operating member 162. Specifically, the link 161 is movably connected to the base frame 130, and one end of the link 161 is connected to the locking member 150. The operating member 162 is connected to the base frame 130, and one end of the operating member 162 is connected to the other end of the link 161 away from the locking member 150. It should be noted that when the locking member 150 is in the locked position, it is used to limit the support member 141 to a supported position or a retracted position; when the locking member 150 is in the unlocked position, the support member 141 can move between the supported position and the retracted position.

[0132] According to the chassis system 120 of this solution, by setting the drive component 160 to drive the locking component 150 to move between the locked position and the unlocked position, it is convenient to control the movement of the support component 141 between the supporting position and the storage position; that is, by cooperating with the operating component 162 and the connecting rod 161, it is convenient for the user to operate, thereby making it easy to control the position adjustment of the support component 141, eliminating the problem of application difficulties of the chassis system 120 caused by the constraints of the vehicle chassis.

[0133] Furthermore, in the illustrated embodiment, the support member 141 is pivotally connected to the base frame 130 between a supported position and a retracted position about a first axis extending along a first horizontal direction D1. The locking member 150 is movably connected to the support member 141 between a locked position and an unlocked position along a second horizontal direction D2 perpendicular to the first horizontal direction D1.

[0134] Please see now Figure 5 and Figure 6The base frame 130 is provided with a sleeve 136, and a support member 141 is pivotally connected to the sleeve 136 about the aforementioned first axis. The sleeve 136 and the support member 141 are provided with corresponding insertion holes 137. A locking member 150 in the locked position is connected to the insertion holes 137 of both the sleeve 136 and the support member 141, while the locking member 150 in the unlocked position is separated from the insertion holes 137 of both (i.e., the sleeve 136 and the support member 141). That is, the locking member 150 in the locked position partially extends into the interior of the support member 141. Furthermore, the base frame system 120 also includes a guide sleeve 151 and an end seat 153. The guide sleeve 151 has an internal receiving cavity 152 and one end is connected to the sleeve 136 (e.g., by welding), and the receiving cavity 152 communicates with the insertion holes 137 of both. It is understood that the so-called "connection" here should refer to the situation where the insertion hole 137 of the sleeve 136 corresponds to the insertion hole 137 of the support member 141; in other words, it should refer to the situation where the support member 141 is in the support position. The end seat 153 is connected to the other end of the guide sleeve 151 away from the sleeve 136, and the end seat 153 has a through hole 154 that connects to the outside and the receiving cavity 152. It should be noted that the locking member 150 is disposed in the receiving cavity 152 and movably connected to the guide sleeve 151. One end of the locking member 150 is used to connect to the insertion hole 137 (of the sleeve 136 and the support member 141), and the other end of the locking member 150 away from the insertion hole 137 extends to the outside through the through hole 154 and is connected to the drive assembly 160.

[0135] Please continue reading. Figure 5 and Figure 6 The locking member 150 is constructed as a pin. Specifically, the locking member 150 includes a plug portion 155, a stop portion 156, and a driven portion 157. The plug portion 155 is used to connect to the socket 137. The stop portion 156 is disposed in the receiving cavity 152 and connected to the end of the plug portion 155 away from the socket 137. One end of the driven portion 157 is connected to the other end of the stop portion 156 away from the plug portion 155, and the other end of the driven portion 157 away from the stop portion 156 extends to the outside via a through hole 154 and is connected to the drive assembly 160. The radial dimension of the stop portion 156 is at least larger than the radial dimension of the driven portion 157. In other words, the stop portion 156 protrudes at least from the driven portion 157 radially away from the axis of the locking member 150 (pin). Figure 6In this configuration, the radial dimension of the stop portion 156 is larger than that of the insertion portion 155 and the driven portion 157. That is, the locking member 150 is constructed as a stepped shaft structure. Preferably, the outer diameter of the stop portion 156 is the same as or substantially the same as the inner diameter of the receiving cavity 152. The base system 120 also includes an elastic member 158, which is disposed in the receiving cavity 152 and sleeved onto the outer periphery of the driven portion 157. The elastic member 158 is located between the stop portion 156 and the end seat 153 to prevent slippage. The elastic member 158 is used to drive the locking member 150 from the unlocked position to the locked position. It is understood that the elastic member 158 can be constructed as a spring.

[0136] In the illustrated embodiment, the drive assembly 160 includes a link 161 and an operating member 162. Specifically, the link 161 is movably connected to the base frame 130 along a second horizontal direction D2, and one end of the link 161 is connected to the locking member 150. As described above, the link 161 is connected to the driven part 157. The operating member 162 is pivotally connected to the base frame 130 about a second axis extending in the vertical direction DH. It should be noted that one end of the operating member 162 is pivotally connected to the other end of the link 161 away from the locking member 150 about a third axis extending in the vertical direction DH. The other end of the operating member 162 away from the link 161 may protrude outward from the base frame 130. It is understood that the operating member 162 (e.g., configured as a handle) is easily accessible and operable by the operator, thereby facilitating the operator's control of the position of the locking member 150. Of course, the operating component 162 can also be configured to be flush with or close to the edge of the chassis 130, as long as it is easy for the operator to access and operate. In other words, the user can extend the operation by controlling the position of the locking component 150 through the mechanism formed by the operating component 162 and the linkage 161, thereby eliminating the problem of application difficulties of the chassis system 120 caused by the constraints of the vehicle chassis.

[0137] To facilitate the operator's access to and operation of the aforementioned operating component 162, the following further explanation of the configuration of the operating component 162 is provided. Please refer to [link / reference needed]. Figure 5 Specifically, the operating member 162 has an operating end 168 for user operation. The connection position between the operating member 162 and the base frame 130 is configured as a first connection position 169, and the connection position between the operating member 162 and the connecting rod 161 is configured as a second connection position 176. It can be understood that the first connection position 169 is located between the operating end 168 and the second connection position 176. It should be noted that, along the extending direction of the operating member 162, the distance between the first connection position 169 and the second connection position 176 does not exceed 1 / 3 of the distance between the first connection position 169 and the operating end 168.

[0138] As described above, when the locking member 150 is in the unlocked position, the elastic member 158 is in a compressed state; in other words, the elastic member 158 has a spring force that drives the locking member 150 from the unlocked position to the locked position. This spring force will drive the operating member 162 to move through the linkage 161. In order to keep the locking member 150 in the unlocked position, the base system 120 also includes a first limiting member 164, which is disposed in the base 130. Specifically, when the locking member 150 is in the unlocked position, the first limiting member 164 is used to connect to the operating member 162 so that the locking member 150 is kept in the unlocked position. It is conceivable that if the aforementioned elastic member 158 fails, the locking member 150 may also lose its ability to remain in the locked position. Therefore, the base system 120 also includes a second limiting member 165, which is disposed in the base 130. When the locking member 150 is in the locked position, the second limiting member 165 is connected to the operating member 162 so that the locking member 150 is held in the locked position. Figure 5 In the middle, the first limiting member 164 and the second limiting member 165 are arranged at intervals along the second horizontal direction D2.

[0139] Please see now Figures 7 to 9 Preferably, both the first limiting member 164 and the second limiting member 165 are pivotally connected to the base frame 130 about an axis extending along the first horizontal direction D1. Specifically, the base frame 130 is provided with a first base 166 and a second base 167, which have the same structure. Both the first limiting member 164 and the second limiting member 165 are configured as hooks suitable for operating member 162. The first limiting member 164 is pivotally connected to the first base 166 about an axis extending along the first horizontal direction D1, and the second limiting member 165 is pivotally connected to the second base 167 about an axis extending along the first horizontal direction D1. The cross-sections of both the first base 166 and the second base 167 are configured as U-shaped with the opening facing upwards (see...). Figure 8 Both the first limiting member 164 and the second limiting member 165 can tilt downward relative to the base frame 130 under their own weight, facilitating connection with the operating member 162. Correspondingly, by moving the first limiting member 164 and / or the second limiting member 165 upward, the connection with the operating member 162 can be released, facilitating operation of the operating member 162. In other words, the first base 166 and the second base 167 facilitate control over the pivoting adjustment of the corresponding limiting members (the first base 166 corresponds to the first limiting member 164, and the second base 167 corresponds to the second limiting member 165), and can control the degree of downward pivoting of the corresponding limiting members under their own weight, ensuring that the operating member 162 can engage with the limiting members.

[0140] Please return to the reference section. Figure 2 and Figure 5 The base frame system 120 also includes diagonal braces 144, which are connected to and movable with support members 141. Each diagonal brace 144 corresponds to one support member 141, and the combination of diagonal braces 144 and support members 141 can be referred to as a support assembly 140. Specifically, one end of the diagonal brace 144 is pivotally connected to the support member 141 about a fourth axis extending along a first horizontal direction D1. When the support member 141 is in the supported position, the other end of the diagonal brace 144, away from the support member 141, can be connected to the base frame 130. When the diagonal brace 144 is connected to the base frame 130, it is inclined relative to the first horizontal direction D1 and the vertical direction DH.

[0141] Please continue reading. Figure 2 and Figure 5 The support member 141 includes a first arm 142 and a second arm 143. The first arm 142 is disposed along a first horizontal direction D1 and is pivotally connected to the base frame 130 about a first axis. The second arm 143 is connected to one end of the first arm 142 and is perpendicular to the first arm 142. It should be noted that when the support member 141 is in the supported position, the other end of the second arm 143 away from the first arm 142 extends downward along the vertical direction DH; when the support member 141 is in the retracted position, the other end of the second arm 143 away from the first arm 142 extends along a second horizontal direction D2 toward a position close to the center of the base frame 130. Specifically, one end of the diagonal brace 144 is pivotally connected to the second arm 143 about a fourth axis; when the diagonal brace 144 is pivoted to be parallel to the second arm 143, the diagonal brace 144 can be fixedly connected to the second arm 143. This will be explained in detail below.

[0142] Please see now Figures 10 to 12 The support member 141 is movably connected to the base frame 130 along the first horizontal direction D1 between a first position and a second position. Specifically, the support member 141 in the first position does not protrude outward from the base frame 130 along the first horizontal direction D1 (see...). Figure 12 The support member 141, located in the second position, protrudes outward from the base frame 130 along the first horizontal direction D1 (see...). Figure 11Specifically, in actual use, the support member 141 in the first position is typically located in the aforementioned storage position; the support member 141 in the second position is located in the aforementioned support position. Furthermore, to prevent the support member 141 from slipping off the sleeve 136, the support assembly 140 also includes a stop bar 148. The stop bar 148 is disposed on the support member 141 and can move with the support member 141. Specifically, the stop bar 148 is connected to the end of the first arm 142 away from the second arm 143. When the support member 141 is in the second position, the stop bar 148 can abut against the sleeve 136, thereby preventing the support member 141 from slipping off the sleeve 136. Figure 11 In the middle, the diagonal brace 144 pivots to a position parallel to the second arm 143. (See also...) Figure 11 and Figure 13 The diagonal brace 144 is provided with a flange 147, and correspondingly, the second arm 143 can be provided with a hole suitable for the flange 147, thereby realizing a detachable connection between the diagonal brace 144 and the second arm 143.

[0143] Please see now Figure 5 , Figures 13 to 15 As those skilled in the art will know, the base frame 130 generally includes bottom side beams 131, bottom end beams 132, and bottom corner members. The bottom side beams 131, bottom end beams 132, and bottom corner members enclose a generally rectangular frame, and multiple bottom crossbeams 138 are typically provided on the inner side of the frame. The two ends of the bottom crossbeams 138 are respectively connected to two bottom side beams 131. The cross-sectional structure of the bottom side beams 131 is U-shaped with the opening facing outwards from the base frame 130. To improve the overall structural strength of the bottom side beams 131, reinforcing members 133 are also provided on the inner side of the bottom side beams 131. A fixing member 134 is provided at the reinforcing member 133. When the supporting member 141 is in the supporting position, the other end of the diagonal brace 144 away from the supporting member 141 can pivot to abut against the fixing member 134. Specifically, the fixing member 134 has an abutment surface 135 that is inclined relative to both the second horizontal direction D2 and the vertical direction DH. Figure 13 In this configuration, the diagonal brace 144 has a pivot portion 144a for pivotal connection with the support member 141; the diagonal brace 144 also includes an overlapping plate 146 for abutting against the fixing member 134. (See also...) Figure 13 and Figure 14It can be seen that the overlapping plate 146 has a limiting hole 146a, and the fixing member 134 has a limiting post 139 adapted to the limiting hole 146a. In other words, when the other end of the diagonal brace 144 is pivoted to abut against the fixing member 134, the overlapping plate can be fitted onto the outer periphery of the limiting post 139 through the limiting hole 146a. That is, when the supporting member 141 is in the supporting position, the other end of the diagonal brace 144 away from the supporting member 141 can be connected to the base frame 130. Specifically, the base frame 130 includes a bottom side beam 131, the inner side of which is connected to a reinforcing member 133, and the diagonal brace 144 is configured to connect to the reinforcing member 133. It should be noted that... Figure 5 In this system, the base frame system 120 also includes a suspension member 145 disposed on the support member 141. When the support member 141 is in the retracted position, the suspension member 145 can be connected to the base frame 130 to prevent the support member 141 from pivoting toward the supported position. For example, the suspension member 145 is configured as a hook adapted to the bottom side beam 131, so that when the support member 141 is in the retracted position, the suspension member 145 can engage with the bottom side beam 131, thereby keeping the support member 141 in the retracted position.

[0144] As described above, the support member 141 is movable between a first position and a second position. In some applications, it is necessary for the support member 141 to remain in the first position. Therefore, the underframe system 120 also includes a stop 171, which is movably connected to the underframe 130 between a stop position and a release position. It should be noted that when the stop 171 is in the release position, the support member 141 is movable between the first and second positions; when the support member 141 is in the first position, the stop 171 in the stop position prevents the support member 141 from moving towards the second position. Specifically, please refer to... Figure 16 and Figure 17 A mounting member 170 is provided at the bottom side beam 131, and a fastener 175 is installed at the mounting member 170. The axis of the fastener 175 extends along the first horizontal direction D1. The blocking member 171 includes a first blocking plate 172 and a second blocking plate 173 connected to each other. The first blocking plate 172 has a connecting groove 174 and passes through the connecting groove 174 to the outer periphery of the fastener 175. The connecting groove 174 is elongated, meaning that the first blocking plate 172 can pivot relative to the fastener 175, and the first blocking plate 172 can also move relative to the fastener 175 along the extension direction of the connecting groove 174. The second blocking plate 173 can pivot and / or move with the first blocking plate 172. When no external force is applied to the blocking member 171, the blocking member 171 can naturally droop under its own weight, at which time the blocking member 171 is in the blocking position. Figure 17In the first position, the support member 141 is located and cannot move to the second position. It can be understood that after the blocking member 171 is flipped upward (i.e., the blocking member 171 is in the release position), the support member 141 can move from the first position to the second position.

[0145] The following describes the movement process of the locking member 150.

[0146] Please return to the reference section. Figure 5 and Figure 6 , Figure 5 In this configuration, the operating component 162 is connected to the second limiting component 165, at which point the locking component 150 is in the locked position. First, the second limiting component 165 is flipped upwards, disengaging it from the operating component 162. Then, the operator rotates the operating component 162, connecting it to the first limiting component 164. The operating component 162 is rotatably connected to the base frame 130 via a connecting component 163. The connecting component 163 is U-shaped and provides fixation and support for the operating component 162, preventing it from wobbling. The connecting rod 161 is C-shaped and has a length of not less than 1000 mm. In this embodiment, the length of the connecting rod 161 is 1275.5 mm. The connection point between the operating component 162 and the connecting component 163 (i.e., the first connection position 169) is located between the connection point between the operating component 162 and the connecting rod 161 (i.e., the second connection position) and the operating end 168 of the operating component 162. Preferably, the distance from the connection point between the operating member 162 and the connecting member 163 to the operating end 168 is not less than 300mm. In this embodiment, the length of the operating member 162 is 368mm. During the process of the operating member 162 being connected from the second limiting member 165 to the first limiting member 164, the operating member 162 rotates around the connection point between the operating member 162 and the connecting member 163. Figure 5 In the middle (clockwise rotation), the connecting rod 161 moves along the second horizontal direction D2, following the operating member 162. The connecting rod 161 drives the locking member 150 from the locked position to the unlocked position (see...). Figure 6 ).

[0147] Because the operating member 162 is connected to the first limiting member 164, and with the assistance of the U-shaped connecting member 163, the operating member 162 will remain at the first limiting member 164 and will not be able to pivot further. When the operator flips the first limiting member 164 upwards, the first limiting member 164 will disengage from the operating member 162. The locking member 150 will return from the unlocked position to the locked position under the action of the elastic member 158. During this process, the connecting rod 161 moves along the second horizontal direction D2 following the locking member 150, and the operating member 162 rotates about the connection point between the operating member 162 and the connecting member 163. Figure 5(In the middle, it is the reverse pointer rotation). Connecting the operating member 162 to the second limiting member 165 will keep the locking member 150 in the locked position.

[0148] This utility model also provides a container.

[0149] Please see now Figure 1 The container 100 includes a container body 110 and the aforementioned underframe system 120. The underframe system 120 is located below and connected to the container body 110. Preferably, the aforementioned first horizontal direction D1 is configured in the width direction of the container 100, and correspondingly, the second horizontal direction D2 is configured in the length direction of the container 100. Further details can be found in the following description. Figure 1 and Figure 2 The support members 141 are arranged in pairs, with the two support members 141 in a pair spaced apart along the width direction of the container 100. There are multiple pairs of support members 141, with each pair of support members 141 spaced apart from the other pairs of support members 141 along the length direction of the container 100. At least one pair of locking members 150 and a corresponding drive assembly 160 are provided on the support member 141 near the end of the container 100. One end of the locking member 150 is connected to the support member 141, and the drive assembly 160 is connected to the other end of the locking member 150 away from the support member 141. Preferably, the container 100 is constructed as an exchangeable container.

[0150] According to the container of this utility model, the setting of the drive component allows the operator to operate from a position near the middle of the base frame, thereby controlling the movement of the locking component between the locked and unlocked positions. This eliminates the problem of application difficulties of the exchange container caused by the constraints of the vehicle chassis, greatly improves the application prospects, and solves the technical pain point of difficult opening and closing of the locking component with a small increase in cost, ensuring the competitiveness of the exchange container in the future market.
