[0054] The mounting structure 100 of the cargo box 200 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0055] Reference Figures 1-26 As shown, the mounting structure 100 according to an embodiment of the present invention is used to mount the cargo box 200 onto the frame 300 of the vehicle 1000. The cargo box 200 serves a loading function, for example, loading goods. The cargo box 200 may or may not have an openable and closable door. The weight, length, height, or width of the cargo box 200 are not limited, as long as the cargo box 200 can be mounted on the frame 300 to serve its loading function.

[0056] Specifically, the mounting structure 100 may include at least three mounting components 10. Each mounting component 10 includes a detachably connected mounting member 14 and a mounting mating member 15. One of the mounting member 14 and the mounting mating member 15 is mounted on the vehicle frame 300 and the other is mounted on the cargo box 200. The mounting member 14 is provided with a mounting hole 141, and the mounting mating member 15 is provided with a mounting mating hole 151 that mates with the mounting hole 141. Fasteners 30 pass through the mounting hole 141 and the mounting mating hole 151 to connect the mounting member 14 and the mounting mating member 15.

[0057] The detachable connection method can be a threaded connection or a snap-fit, etc., and correspondingly, the fastener 30 can be a bolt or a snap-fit, etc. For example, in some embodiments, such as Figures 1-8 As shown, the left longitudinal beam 310 and the right longitudinal beam 320 of the frame 300 are both equipped with mounting parts 14, and the left longitudinal beam 210 and the right longitudinal beam 220 of the cargo box 200 are both equipped with mounting mating parts 15. The fasteners 30 are bolts, which pass through the mounting holes 141 and the mounting mating holes 151 to securely install the cargo box 200 onto the frame 300.

[0058] At least two mounting components 10 are along the length of the frame 300 (e.g.) Figures 1-2 Arranged in the front-to-back direction as shown, at least two mounting components 10 are along the width direction of the frame 300 (e.g., in the front-to-back direction). Figures 1-2The arrangement (as shown in the left-right direction) ensures that the number of mounting positions of the cargo box 200 and the frame 300 on the horizontal plane perpendicular to the length and width directions is greater than or equal to 3, and all mounting components 10 are not arranged along the same straight line, so that the cargo box 200 and the frame 300 are arranged along the height direction of the frame 300 (e.g., in the left-right direction). Figure 2 The vertical direction (as shown) is not prone to relative movement.

[0059] For example, in some embodiments, such as Figure 1 As shown, the installation structure 100 includes four installation components 10. Two of the four installation components 10 are arranged in the front-to-back direction and two in the left-to-right direction, so as to install the cargo box 200 and the frame 300 at four points in the up-down direction. With a large number of installation positions, the cargo box 200 and the frame 300 are installed more firmly.

[0060] Multiple mounting components 10 include a first mounting component 11 and a second mounting component 12. The mounting member 14 of the first mounting component 11 is provided with a first locating pin 142, and the mounting mating member 15 of the first mounting component 11 is provided with a first locating hole 152 that mates with the first locating pin 142. The mounting member 14 of the second mounting component 12 is provided with a second locating pin 143, and the mounting mating member 15 of the second mounting component 12 is provided with a second locating hole 153 that mates with the second locating pin 143. The first mounting component 11 and the second mounting component 12 are arranged horizontally. In a direction perpendicular to the arrangement direction of the first mounting component 11 and the second mounting component 12, the size h1 of the first locating hole 152 is equal to the size h2 of the first locating pin 142, and the size h3 of the second locating hole 153 is equal to the size h4 of the second locating pin 143. In the arrangement direction of the first mounting component 11 and the second mounting component 12, the size h5 of the first locating hole 152 is equal to the size h6 of the first locating pin 142, and the size h7 of the second locating hole 153 is greater than the size h8 of the second locating pin 143.

[0061] It should be noted that the dimension of the positioning hole (first positioning hole 152 or second positioning hole 153) in any direction is the minimum dimension of the positioning hole in that direction, and the dimension of the positioning pin (first positioning pin 142 or second positioning pin 143) in any direction is the maximum dimension of the positioning pin in that direction. The above comparison of the dimensions of the positioning hole and the positioning pin is valid within the allowable error range, such as within the error range of assembly errors.

[0062] The first mounting component 11 and the second mounting component 12 can be arranged opposite each other and spaced apart along the length of the frame 300, for example Figures 1-3As shown, the first mounting assembly 11 and the second mounting assembly 12 are located at the front left and rear left portions of the frame 300, respectively. The first mounting assembly 11 and the second mounting assembly 12 may also be spaced apart along the length of the frame 300 and spaced apart along the width, for example, the first mounting assembly 11 and the second mounting assembly 12 may be located at the front left and rear right portions of the frame 300, respectively. The first mounting assembly 11 and the second mounting assembly 12 may also be spaced apart along the width of the frame 300, for example, the first mounting assembly 11 and the second mounting assembly 12 may be located at the front left and front right portions of the frame 300, respectively.

[0063] like Figure 5 and Figures 9-10 As shown, for the first mounting assembly 11, in the arrangement direction of the first mounting assembly 11 and the second mounting assembly 12 and in the direction perpendicular to the arrangement direction (i.e., the arrangement direction of the first mounting assembly 11 and the second mounting assembly 12), the size of the first positioning hole 152 is equal to the size of the first positioning pin 142, so that the cargo box 200 and the frame 300 are positioned at the first mounting assembly 11 in the direction perpendicular to the arrangement direction through the cooperation of the first positioning hole 152 and the first positioning pin 142, so that the cargo box 200 and the frame 300 are not easily moved relative to each other at the first mounting assembly 11 in the direction perpendicular to the arrangement direction.

[0064] like Figure 6 and Figures 11-12 As shown, for the second mounting assembly 12, in a direction perpendicular to the aforementioned arrangement direction, the size h3 of the second positioning hole 153 is equal to the size h4 of the second positioning pin 143. This allows the cargo box 200 and the frame 300 to be positioned along this direction at the second mounting assembly 12 through the cooperation of the second positioning hole 153 and the second positioning pin 143, preventing relative movement between the cargo box 200 and the frame 300 at the second mounting assembly 12. In the aforementioned arrangement direction, the size h7 of the second positioning hole 153 is larger than the size h8 of the second positioning pin 143, allowing the cargo box 200 and the frame 300 at the second mounting assembly 12 to absorb dimensional deviations in this direction. The cargo box 200 and the frame 300 have a certain amount of room to move along this direction, reducing the likelihood of over-positioning. This prevents interference-induced jamming during assembly and avoids gaps that could cause inaccurate positioning. The manufacturing precision and installation operation requirements are low, making it easy to implement.

[0065] For example, in some specific embodiments, such as Figure 10 and Figure 12As shown, the first mounting assembly 11 and the second mounting assembly 12 are located on the front left and rear left portions of the frame 300, respectively. The first positioning hole 152 is a circular hole, and the first positioning pin 142 is a circular pin. In the front-rear and left-right directions, the diameter of the first positioning hole 152 is equal to the diameter of the second positioning hole 153. The second positioning hole 153 is an oblong hole, and the second positioning pin 143 is a circular pin. In the left-right direction, the size of the second positioning hole 153 is equal to the diameter of the second positioning pin 143, and in the front-rear direction, the size of the second positioning hole 153 is larger than the diameter of the second positioning pin 143.

[0066] The positioning of the cargo box 200 and the frame 300 is achieved by using pin holes. The positioning structure of the positioning pin is a complete outer surface, and the positioning structure of the positioning hole is a complete inner surface. The positioning structures of the positioning pin and the positioning hole are located on the same positioning surface. Compared with the profile positioning structure that includes multiple positioning surfaces, the pin hole positioning structure in this application has high controllability of manufacturing precision, small positioning error, low difficulty in assembling and positioning the cargo box 200 and the frame 300, and high assembly efficiency and precision.

[0067] By using the first mounting component 11 and the second mounting component 12, the cargo box 200 and the frame 300 are positioned at two points in the direction perpendicular to the aforementioned arrangement direction and at one point in the aforementioned arrangement direction. Combined with the arrangement of multiple mounting components 10 on the horizontal plane, the cargo box 200 and the frame 300 are positioned at least three points in the height direction. The "N-2-1" positioning principle can be used to achieve precise positioning of the cargo box 200 on the frame 300, thereby restricting the six degrees of freedom of the cargo box 200 and firmly connecting the cargo box 200 and the frame 300 together.

[0068] In some related technologies, during the assembly of the cargo box and chassis, the cargo box is lowered onto the chassis from top to bottom. Because there is no guiding positioning structure between the cargo box and the chassis, misalignment is easy, making it difficult to align the cargo box and chassis at their installation positions. Operators need to repeatedly adjust the cargo box position to align it with the chassis, affecting assembly efficiency. Furthermore, there are multiple installation positions for the cargo box and chassis. After aligning one position, bolts need to be installed for temporary positioning before aligning other positions. This process requires repeatedly lifting the cargo box to adjust its relative position to the chassis, resulting in low assembly efficiency and increasing the risk of damage to the installed bolts, reducing the stability of the temporary positioning positions.

[0069] This application utilizes multiple mounting components 10, in which the first positioning hole 152 and the first positioning pin 142 cooperate, and the second positioning hole 153 and the second positioning pin 143 cooperate, to achieve precise positioning of the cargo box 200 and the frame 300. This allows for the alignment of the cargo box 200 during assembly, making it easy to align the installation positions of the truck and the frame 300. This eliminates the need for operators to repeatedly adjust the position of the cargo box 200, facilitating the installation of the cargo box 200 onto the frame 300. The assembly efficiency of the cargo box 200 and the frame 300 is relatively high.

[0070] Furthermore, this application can align multiple installation positions of the cargo box 200 and the frame 300 at one time through the first installation component 11 and the second installation component 12, without having to repeatedly lift the cargo box 200 to adjust the relative position of the cargo box 200 and the frame 300. This not only improves assembly efficiency but also reduces the risk of damage to the fasteners 30, thus improving the installation firmness of the installation position.

[0071] According to the mounting structure 100 of the cargo box 200 in this embodiment of the present utility model, the cargo box 200 can be mounted on the frame 300. Through the cooperation of the first positioning hole 152 and the first positioning pin 142, and the cooperation of the second positioning hole 153 and the second positioning pin 143, the cargo box 200 can be accurately positioned on the frame 300, thereby improving the assembly accuracy and assembly efficiency. The fasteners 30 are used to improve the assembly firmness.

[0072] In some embodiments of this utility model, such as Figures 1-3 As shown, the first mounting component 11 and the second mounting component 12 are arranged opposite to each other and spaced apart along the length direction. The length dimension of the cargo box 200 is larger than the width dimension of the cargo box 200, so as to position the longer part of the cargo box 200 and make the distance between the two positioning points longer, so that the cargo box 200 and the frame 300 are less likely to move relative to each other. This results in high positioning accuracy and better positioning effect between the cargo box 200 and the frame 300.

[0073] For example, in some specific embodiments, such as Figures 1-3 As shown, the length direction of the cargo box 200 and the frame 300 is parallel to the front-rear direction in the figure, and the width direction of the cargo box 200 and the frame 300 is parallel to the left-right direction in the figure. The dimension of the cargo box 200 in the front-rear direction is larger than the dimension of the cargo box 200 in the left-right direction. The first mounting component 11 is located at the front part of the left longitudinal beam 210 of the cargo box, and the second mounting component 12 is located at the rear part of the left longitudinal beam 210 of the cargo box, so that the first mounting component 11 and the second mounting component 12 are arranged opposite each other and spaced apart in the front-rear direction.

[0074] In some embodiments, such as Figure 2As shown, the distance between the first mounting component 11 and the second mounting component 12 along the length direction is 'a', and the size of the cargo box 200 is 'b', where b / 3 ≤ a ≤ b*5 / 6. It should be noted that the distance between the first mounting component 11 and the second mounting component 12 is the distance between their respective geometric centers, and the size of the cargo box 200 is its maximum size. If 'a' is too small, the two positioning points may be too close, resulting in poor positioning accuracy and poor positioning effect between the cargo box 200 and the frame 300. If 'a' is too large, the two positioning points may be difficult to align, increasing assembly difficulty. Therefore, b / 3 ≤ a ≤ b*5 / 6 is beneficial for balancing positioning accuracy and assembly efficiency requirements. For example, 'a' can be equal to b / 3, b*2 / 3, or b*5 / 6, etc.

[0075] In some embodiments, such as Figure 2 , Figure 4 , Figures 7-8 and Figures 13-23 As shown, the plurality of mounting components 10 includes at least one third mounting component 13. The mounting member 14 of the third mounting component 13 has a mounting hole 141, and the mounting mating member 15 of the third mounting component 13 has a mounting mating hole 151. The first mounting component 11 and the third mounting component 13 are arranged spaced apart along the width direction. That is, at the third mounting component 13, the mounting member 14 has a mounting hole 141 and does not require a locating pin, and the mounting mating member 15 has a mounting mating hole 151 and does not require a locating hole. Of course, the mounting mating member 15 can also have a locating hole, so that the first mounting component 11, the second mounting component 12, and the third mounting component 13 all use the same mounting mating member 15, eliminating the need to produce different types of mounting mating members 15, which helps reduce costs and facilitates maintenance or replacement of the mounting mating members 15 of different mounting components 10.

[0076] The third mounting component 13 facilitates the secure installation of the cargo box 200 onto the frame 300 using fasteners 30. The third mounting component 13 and the first mounting component 11 are arranged at a distance along the width direction. The cargo box 200 can also be installed on the frame 300 at the first mounting component 11 using fasteners 30. This makes the different mounting points far apart, and the cargo box 200 and the frame 300 are less likely to move relative to each other, resulting in a more secure installation.

[0077] For example, in some specific embodiments, such as Figure 2 and Figure 4As shown, the multiple mounting components 10 include two third mounting components 13, which are respectively installed on the front and rear parts of the right longitudinal beam 220 of the cargo box. The first mounting component 11 is installed on the front part of the left longitudinal beam 210 of the cargo box, and the second mounting component 12 is installed on the rear part of the left longitudinal beam 210 of the cargo box. The first mounting component 11 and the third mounting component 13 are arranged alternately in the left-right direction, and the first mounting component 11 and the second mounting component 12 are arranged alternately in the front-back direction. This increases the distance between the two positioning points and the distance between any two mounting points of the four mounting components 10, resulting in higher positioning accuracy of the cargo box 200 and the frame 300, and a more secure installation.

[0078] In some embodiments of this utility model, such as Figure 10 , Figure 12 and Figures 15-17 As shown, both the first positioning pin 142 and the second positioning pin 143 include a first segment 144 and a second segment 145. The first segment 144 connects the mounting member 14 and the second segment 145. In the arrangement direction of the mounting member 14 and the mounting mating member 15, the cross-sectional area of ​​the second segment 145 perpendicular to the arrangement direction gradually decreases in the direction away from the mounting member 14. The first positioning hole 152 mates with the first segment 144 of the first positioning pin 142, and the second positioning holes 153 all mate with the first segment 144 of the second positioning pin 143.

[0079] By changing the cross-sectional area of ​​the second segment 145, the second segment 145 is formed into a conical shape. In order to guide the positioning hole during the engagement of the positioning pin and the positioning hole, the positioning pin and the positioning hole are less likely to be severely scratched. The installation of the cargo box 200 on the frame 300 is smoother. The cargo box 200 falls smoothly onto the frame 300, so that the first segment 144 and the positioning hole are engaged, realizing the positioning and installation of the cargo box 200 on the frame 300.

[0080] For example, in some specific embodiments, such as Figure 10 , Figure 12 and Figures 24-26 As shown, the height direction of the cargo box 200 and the frame 300 is parallel to the vertical direction in the figure. The mounting part 14 is located below the mounting mating part 15. The positioning pin includes a first section 144 and a second section 145 arranged in the vertical direction. The first section 144 connects the mounting part 14 and the second section 145. The cross-sectional area of ​​the second section 145 along the horizontal plane gradually decreases from bottom to top to form a conical shape. When the cargo box 200 falls onto the frame 300, the positioning hole is guided downward through the second section 145 and then mates with the first section 144.

[0081] In some embodiments of this utility model, such as Figures 18-23As shown, the mounting fitting 15 has a flange 154 on the side facing away from the mounting member 14. The flange 154 defines a first positioning hole 152 or a second positioning hole 153. The size of the flange 154 gradually decreases in the direction away from the mounting member 14. It should be noted that the smallest part of the flange 154 defines the positioning hole, for example... Figures 18-23 The mounting part 14 is located on the lower side of the mounting mating part 15. The size of the flange 154 is the inner diameter of the flange 154. The inner diameter of the flange 154 gradually decreases from bottom to top. The upper end of the flange 154 has the smallest size, so that the upper end of the flange 154 defines the positioning hole.

[0082] The dimensions of the flange 154 gradually decrease in the direction away from the mounting part 14. For example, the inner wall of the flange 154 is rounded so that the positioning pin is guided by the inner wall of the flange 154 during the engagement of the positioning pin and the positioning hole. This makes it less likely for the positioning pin and the inner wall of the flange 154 to cause strong scratches. The installation of the cargo box 200 on the frame 300 is smoother. The cargo box 200 falls smoothly onto the frame 300, so that the positioning pin and the positioning hole engage, thereby achieving the positioning and installation of the cargo box 200 on the frame 300.

[0083] In some embodiments of this utility model, such as Figure 10 and Figures 12-14 As shown, at least one of the mounting component 14 and the mounting mating component 15 is provided with a fastening mating component 155. The fastening mating component 155 is provided with a through hole 156, and at least one of the mounting hole 141 and the mounting mating hole 151 communicates with the through hole 156. The fastening mating component 155 can be provided in at least one of the mounting component 14 and the mounting mating component 15 through welding, riveting, or other methods. The through hole 156 is provided with an internal thread that mates with the fastener 30. The internal thread can be machined into the inner wall of the through hole 156, or a nut or other component with an internal thread can be used directly, which is relatively low cost.

[0084] In some related technologies, mounting components and mounting mating parts are tightened together with bolts and nuts. Operators need to use a tool to hold the nut with one end and tighten the bolt with the other, requiring simultaneous operation with both hands. In addition, when assembling the cargo box, the power system, exhaust system, and other devices on the chassis are already installed, leaving very little space for hand operation, making the tightening of bolts and nuts inconvenient.

[0085] In this application, at least one of the mounting component 14 and the mounting mating component 15 is provided with a fastening mating component 155. This allows the fastener 30 to be connected to the mounting component 14 and the mounting mating component 15 by passing through the mounting hole 141, the mounting mating hole 151 and the through hole 156 of the fastening mating component 155. In other words, only the fastener 30 needs to be operated, unlike the related technologies where separate fasteners and fastening mating components need to be operated simultaneously. This makes the assembly of the cargo box 200 on the frame 300 more convenient and can be operated with one hand, reducing the space required for operation.

[0086] For example, in some embodiments, such as Figure 10 and Figures 12-14 As shown, the fastening fitting 155 is a nut, and the fastener 30 is a bolt. The nut is welded to the upper surface of the mounting fitting 15. During the assembly of the cargo box 200, only the bolt needs to be installed on the lower side of the mounting component 10 to make the bolt and nut threadedly connected, so that the cargo box 200 can be assembled on the frame 300, which reduces the operating space requirement and improves the ease of assembly.

[0087] In some embodiments of this utility model, such as Figures 5-8 , Figure 19 and Figure 22 As shown, the size of the mounting hole 141 or the mounting mating hole 151 is c, and the size of the fastener 30 is d, where 5mm ≤ cd ≤ 7mm. The size of the mounting hole 141 or the mounting mating hole 151 is the minimum inner diameter of the hole, and the size of the fastener 30 is the maximum outer diameter of the fastener 30 passing through the mounting hole 141 and the mounting mating hole 151. For example, in an embodiment where the fastener 30 is a bolt, the size of the fastener 30 is the outer diameter of the bolt's threaded portion.

[0088] If the discrepancy (cd) is too large, the deviation between the mounting part 14 and the mounting mating part 15 will be significant, easily leading to inaccurate positioning of the cargo box 200 and the frame 300, resulting in low assembly precision. If the discrepancy is too small, the fastener 30 may be damaged by collision with the mounting part 14 or the mounting mating part 15 during the process of passing through the mounting hole 141 or the mounting mating hole 151, or even make it difficult to insert the fastener 30 into the mounting hole 141 or the mounting mating hole 151, increasing installation difficulty. A discrepancy of 5mm ≤ cd ≤ 7mm allows the fastener 30 a certain amount of room to move, absorbing deviations such as manufacturing and installation deviations, making it easier to balance assembly precision and installation difficulty requirements. For example, cd can be equal to 5mm, 6mm, or 7mm.

[0089] In some embodiments, such as Figure 19 and Figure 22As shown, the dimensions of both mounting hole 141 and mounting mating hole 151 are c, so that 5mm≤cd≤7mm, which can simultaneously reduce the installation difficulty of fastener 30 and mounting hole 141, and fastener 30 and mounting mating hole 151, making the assembly of cargo box 200 on frame 300 more convenient.

[0090] In some embodiments with fastening fitting 155, during the assembly of cargo box 200 and frame 300, fastener 30 can be passed through mounting hole 141 and mounting fitting hole 151 first, and then fastener 30 and fastening fitting 155 can be threaded together, which facilitates the firm connection of mounting part 14 and mounting fitting 15.

[0091] In some embodiments of this utility model, such as Figures 5-8 As shown, the mounting component 14 has at least two mounting holes 141, and the mounting mating component 15 has at least two mounting mating holes 151. The mounting holes 141 and the mounting mating holes 151 are matched one-to-one, which helps to improve the assembly firmness of the cargo box 200 and the frame 300. In the arrangement direction of the first mounting component 11 and the second mounting component 12, at least two mounting holes 141 are located on both sides of the first positioning pin 142, and at least two mounting holes 141 are located on both sides of the second positioning pin 143. This allows the cargo box 200 to be aligned with the frame 300 using the cooperation of the positioning pins and positioning holes. The mounting holes 141 on both sides of the positioning pins can enhance the positioning accuracy of the cargo box 200 and the frame 300, making it less likely for the positioning pins and positioning holes to fail during the process of installing the cargo box 200 onto the frame 300 using fasteners 30, resulting in a more stable positioning effect.

[0092] Furthermore, the mounting holes 141 on both sides of the positioning pin are arranged along the arrangement direction of the first mounting component 11 and the second mounting component 12. The second positioning hole 153 is larger in this direction, which makes it easier to improve the positioning effect at the second positioning hole 153 through the mounting hole 141, so that the cargo box 200 is more firmly installed on the frame 300 and is not easy to shake.

[0093] For example, in some specific embodiments, such as Figures 1-8 As shown, in the left-right direction, the outer diameter of the first positioning pin 142 is equal to the inner diameter of the first positioning hole 152, and the outer diameter of the second positioning pin 143 is equal to the size of the second positioning pin 143. In the front-back direction, the outer diameter of the first positioning pin 142 is equal to the inner diameter of the first positioning hole 152, and the outer diameter of the second positioning pin 143 is larger than the size of the second positioning pin 143. Two mounting holes 141 are provided on the front and back sides of the positioning pins, and two mounting mating holes 151 are provided on the front and back sides of the positioning holes.

[0094] like Figure 1 and Figures 3-4As shown, a vehicle 1000 according to an embodiment of the present invention includes a cargo box 200, a frame 300, and a mounting structure 100 for the cargo box 200 according to an embodiment of the present invention. The mounting structure 100 is used to mount the cargo box 200 to the frame 300. Since the mounting structure 100 for the cargo box 200 according to an embodiment of the present invention has the aforementioned beneficial technical effects, the vehicle 1000 according to an embodiment of the present invention can mount the cargo box 200 to the frame 300. Furthermore, through the cooperation of the first positioning hole 152 and the first positioning pin 142, and the cooperation of the second positioning hole 153 and the second positioning pin 143, precise positioning of the cargo box 200 on the frame 300 can be achieved, improving assembly accuracy and efficiency. The fasteners 30 further enhance assembly stability.

[0095] In some embodiments, such as Figures 5-8 As shown, a rubber pad 400 is provided between the left longitudinal beam 210 of the cargo box and the left longitudinal beam 310 of the frame, and a rubber pad 400 is provided between the right longitudinal beam 220 of the cargo box and the right longitudinal beam 320 of the frame. The mounting component 14 and the mounting mating component 15 are in contact through the rubber pad 400. The rubber pad 400 can prevent the mounting component 14 and the mounting mating component 15, the cargo box 200 and the frame 300 from being bumped and damaged during the assembly process, which helps to protect the mounting component 14, the mounting mating component 15, the cargo box 200 and the frame 300.

[0096] The following describes in detail, with reference to the accompanying drawings, an installation structure 100 and a vehicle 1000 according to a specific embodiment of the present invention. It is to be understood that the following description is merely illustrative and should not be construed as limiting the present invention.

[0097] like Figures 1-26 As shown, a vehicle 1000 according to a specific embodiment of the present invention includes a mounting structure 100, a cargo box 200 and a frame 300. The mounting structure 100 is used to mount the cargo box 200 to the frame 300, and the cargo box 200 is located on the upper side of the frame 300.

[0098] The mounting structure 100 includes four mounting components 10. Each mounting component 10 includes a detachably connected mounting part 14 and a mounting mating part 15. The mounting part 14 is fixedly mounted to the vehicle frame 300 by welding, riveting, threaded connection, or other methods. The mounting mating part 15 is fixedly mounted to the cargo box 200 by welding, riveting, threaded connection, or other methods.

[0099] The four mounting components 10 are a first mounting component 11, a second mounting component 12, and two third mounting components 13. The first mounting component 11 is located in the front left part of the cargo box 200, the second mounting component 12 is located in the rear left part of the cargo box 200, and the two third mounting components 13 are located in the front right part and the rear right part of the cargo box 200, respectively.

[0100] In the front-rear direction, the distance between the geometric centers of the first mounting component 11 and the second mounting component 12 is a, the size of the cargo box 200 is b, a = b * 2 / 3, the distance between the first mounting component 11 and the front edge of the cargo box 200 is b * 1 / 6, and the distance between the second mounting component 12 and the rear edge of the cargo box 200 is b * 1 / 6. This makes the distance between the first mounting component 11 and the second mounting component 12 relatively large and they are generally installed in the part of the cargo box 200 away from the edge, which has a better positioning effect of the cargo box 200 on the frame 300.

[0101] In the first mounting component 11, the mounting part 14 is provided with a first positioning pin 142 and mounting holes 141 located on the front and rear sides of the first positioning pin 142, and the mounting mating part 15 is provided with a first positioning hole 152 and mounting mating holes 151 located on the front and rear sides of the first positioning hole 152.

[0102] Specifically, two mounting holes 141 and two mounting mating holes 151 correspond one-to-one in the vertical direction. A fastening fitting 155 is provided on the upper side of each mounting mating hole 151. The fastening fitting 155 is welded to the mounting fitting 15 and has a through hole 156 communicating with the mounting mating hole 151. The through hole 156 has a thread that mates with the fastener 30. The outer diameter of the fastener 30 is larger than the inner diameter of the mounting holes 141 and 151. After passing through the mounting holes 141 and 151, the fastener 30 is threadedly connected to the fastening fitting 155. The fastener 30 is a bolt, and the fastening fitting 155 is a nut.

[0103] The first locating pin 142 includes a first segment 144 and a second segment 145, with the first segment 144 connecting the mounting member 14 and the second segment 145. In the vertical direction, the cross-sectional area of ​​the second segment 145 gradually decreases from bottom to top along the horizontal plane, and the first locating hole 152 mates with the first segment 144. The first locating hole 152 is defined by a flange 154, which is located on the upper side of the mounting member 15. The inner diameter of the flange 154 gradually increases from bottom to top, and the upper end of the flange 154 defines the first locating hole 152, guiding the mating of the first locating hole 152 and the first locating pin 142 through the second segment 145 and the flange 154.

[0104] The first positioning hole 152 is a circular hole. In the front-to-back direction, the size of the first positioning hole 152 is equal to the size of the first positioning pin 142; in the left-to-right direction, the size of the first positioning hole 152 is equal to the size of the first positioning pin 142.

[0105] In the second mounting assembly 12, the mounting member 14 is provided with a second positioning pin 143 and mounting holes 141 located on both sides of the second positioning pin 143. The mounting mating member 15 is provided with a second positioning hole 153 and mounting mating holes 151 located on both sides of the second positioning hole 153. Compared with the first mounting assembly 11, the first positioning pin 142 and the second positioning pin 143 are the same in the second mounting assembly 12. The only difference is that the first positioning hole 152 and the second positioning hole 153 are different. Specifically, the second positioning hole 153 is an oblong hole. In the front-back direction, the size of the second positioning hole 153 is larger than the size of the second positioning pin 143; in the left-right direction, the size of the second positioning hole 153 is equal to the size of the second positioning pin 143.

[0106] In the third mounting component 13, the mounting element 14 is provided with two mounting holes 141. For example... Figure 13 As shown, the mounting fitting 15 of the third mounting assembly 13 located on the front right side of the cargo box 200 is provided with a first positioning hole 152 and mounting fitting holes 151 located on both sides of the first positioning hole 152, as shown. Figure 14 As shown, the mounting fitting 15 of the third mounting assembly 13 located in the right rear part of the cargo box 200 is provided with a second positioning hole 153 and mounting fitting holes 151 located on both sides of the second positioning hole 153.

[0107] The third mounting assembly 13, located on the front right side of the cargo box 200, differs from the first mounting assembly 11 only in that the mounting part 14 does not have a first locating pin 142. The third mounting assembly 13, located on the rear right side of the cargo box 200, differs from the first mounting assembly 11 only in that the mounting part 14 does not have a second locating pin 143.

[0108] During the process of assembling the cargo box 200 onto the frame 300, the cargo box 200 is first adjusted to be above the frame 300 and then slowly lowered. Then, the first positioning hole 152 is aligned with the first positioning pin 142, and the second positioning hole 153 is aligned with the second positioning pin 143 to achieve positioning of the cargo box 200 on the frame 300. Then, under the guidance of the flange 154 and the positioning pin, the cargo box 200 is slowly placed onto the upper surface of the frame 300. Then, the mounting holes 141 and mounting mating holes 151 of the four mounting components 10 are fastened with bolts to achieve the fastening installation of the cargo box 200 on the frame 300.

[0109] The mounting structure 100 of the cargo box 200 and other components and operations of the vehicle 1000 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
