However, these exemplary embodiments can be implemented in various different forms, and should not be interpreted as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided in order to make the disclosure of the present utility model complete and comprehensive, and to adequately convey the ideas of these exemplary embodiments to those of ordinary skill in the art.

[0095] Referring to Figures 1 to 3 The present utility model provides a kind of car frame box, including chassis 20 and rotating frame 10.Rotating frame 10 is rotatably connected to chassis 20, to realize the inclination of vehicle transfer.Rotatably or fixedly, end frame 30 is further connected to chassis 20 at two ends of chassis 20.Rotating frame 10 is located between two end frames 30.

[0096] Rotating frame 10 includes body part 200 and support rod 100.

[0097] Referring to Figure 4Optionally, the body part 200 is provided with a tire stopper 700. The tire stopper 700 is used to limit the vehicle. Optionally, the body part 200 is configured as a perforated plate. In some embodiments of the present application, the tire stopper 700 is detachable, which has a latch part 710 and a blocking part 720 arranged oppositely along the length direction thereof. The latch part 710 is inserted into the perforated plate, so that the blocking part 720 can protrude from the upper surface of the body part 200, thereby limiting the tire. Optionally, the latch part 710 has a hook part extending from one hole of the perforated plate to the lower side of the body part 200, and the end of the hook part is hooked to another hole of the perforated plate. The latch part 710 is used to limit and fix the tire by cooperating with the holes of the two rows of perforated plates. The tire stopper 700 can be inserted into different holes of the perforated plates according to the length of the vehicle, and the flexible arrangement of the tire stopper 700 is realized by using the perforated plates on the cross plate 800.

[0098] In the present application, the body part 200 is movably connected to the chassis 20 between the raised position and the folded position. Optionally, the body part 200 is connected to the chassis 20 around the third rotation shaft 210. The body part 200 in the raised position is used to park the vehicle at a certain angle with the ground. The body part 200 in the folded position can be folded onto the chassis 20 to reduce the overall height and space occupation, thereby facilitating transportation and storage. Optionally, at least part of the third rotation shaft 210 is configured as a bearing, a pin shaft or other rotation shaft structure.

[0099] In the present application, the body part 200 is limited to the raised position by supporting the support rod 100 between the body part 200 and the chassis 20. When the body part 200 is rotated to the raised position, the support rod 100 is unfolded and inserted between the body part 200 and the chassis 20 to form a stable triangular support structure (or other stable structure), thereby preventing the body part 200 from accidentally sliding down or falling due to gravity or external force.

[0100] In the utility model, support rod 100 is connected to body part 200. Support rod 100 can rotate with the rotation of body part 200 and can rotate independently. Specifically, the first end of support rod 100 is rotatably connected to body part 200 between the support position and the storage position around first rotation shaft 110, and the second end of support rod 100 located in the support position can be connected to chassis 20 to limit the rotation of body part 200 relative to chassis 20. Optionally, first rotation shaft 110 and third rotation shaft 210 are spaced apart along the length direction of body part 200. In the support position, the second end of support rod 100 can be connected to chassis 20 to limit the rotation of body part 200 relative to chassis 20; in the storage position, support rod 100 can be folded or stored in body part 200 to reduce the occupied space. Without changing the structure of body part 200, the posture of body part 200 is adjusted by the rotation of support rod 100. Specifically, the relative angle of body part 200 and the support of chassis 20 is adjusted. Optionally, at least part of first rotation shaft 110 is configured as a bearing, a pin shaft or other rotation shaft structure.

[0101] Wherein the position of the second end of support rod 100 on chassis 20 is adjustable to adjust the relative angle between body part 200 and chassis 20. Optionally, chassis 20 is provided with different fixing holes 301. Support rod 100 changes the relative angle between body part 200 and chassis 20 by being connected to different fixing holes 301.

[0102] Alternatively, the length of support rod 100 is adjustable. Optionally, support rod 100 is configured as a telescopic structure. By adjusting the length of support rod 100, the relative angle between body part 200 and chassis 20 can be changed.

[0103] According to the above, by the arrangement of movable body part 200, the tilting of the vehicle is realized, so that more vehicles can be carried in the limited space of the vehicle frame box, and the space utilization of the vehicle frame box is improved. By adjusting the position or length of support rod 100, the body part 200 can maintain a stable posture at different lifting positions, improving the practicability and flexibility to meet different use requirements.

[0104] The connection structure of support rod 100 and chassis 20 is introduced below through specific embodiments.

[0105] Referring to Figures 5 to 7 The first embodiment is shown.

[0106] The base frame 20 is provided with fixing seats 310. The fixing seats 310 are formed with fixing holes 311. A plurality of fixing seats 310 correspond to a plurality of fixing holes 311 one by one. That is, the plurality of fixing seats 310 are independent of each other, and each fixing seat 310 is provided with one fixing hole 311. Alternatively, the fixing seat 310 is configured as an ear plate.

[0107] The distance between each fixing hole 311 and the third rotating shaft 210 is different. The fixing hole 311 is located on the moving track of the support rod 100, and the second end of the support rod 100 is selectively fixedly connected with one of the fixing holes 311. Alternatively, the support rod 100 is provided with a connecting hole 101 corresponding to the fixing hole 311. When the support rod 100 is fixed to the base, one of the fixing holes 311 is arranged corresponding to the connecting hole 101, and is fixedly connected through a fixing member. The type of the fixing member includes but is not limited to a bolt and a pin shaft. The connection between the support rod 100 and the base frame 20 is simple and convenient, and the difficulty of use and maintenance is reduced.

[0108] In this embodiment, by changing the connection between the second end of the support rod 100 and different fixing holes 311, the relative angle between the body part 200 and the base frame 20 can be easily adjusted.

[0109] Referring to Figures 8 to 10 the second embodiment shown in the figure.

[0110] The base frame 20 is provided with fixing seats 320. The fixing seats 320 are formed with fixing holes 321. A plurality of fixing holes 321 are formed in one fixing seat 320. Alternatively, the fixing seat 320 is configured as a sliding rail.

[0111] The distance between each fixing hole 321 and the third rotating shaft 210 is different. The fixing hole 321 is located on the moving track of the support rod 100, and the second end of the support rod 100 is selectively fixedly connected with one of the fixing holes 321. Alternatively, the support rod 100 is provided with a connecting hole 101 corresponding to the fixing hole 321. When the support rod 100 is fixed to the base, one of the fixing holes 321 is arranged corresponding to the connecting hole 101, and is fixedly connected through a fixing member. The type of the fixing member includes but is not limited to a bolt and a pin shaft. The connection between the support rod 100 and the base frame 20 is simple and convenient, and the difficulty of use and maintenance is reduced.

[0112] In this embodiment, the support rod 100 can slide on the fixing seat 320 along the length direction of the base frame 20. By changing the connection between the second end of the support rod 100 and different fixing holes 321, the relative angle between the body part 200 and the base frame 20 can be easily adjusted.

[0113] A third embodiment not shown in the figure.

[0114] The chassis 20 is provided with fixing seats 300. The fixing seats 300 are formed with fixing holes 301. The number of the fixing seats 300 is less than the number of the fixing holes 301. The fixing holes 301 are grouped. The fixing holes 301 in the same group are formed in the same fixing seat 300, and the fixing holes 301 in different groups are formed in different fixing seats 300.

[0115] Referring to Figures 5 to 7 In the first embodiment, each fixing seat 300 is independent of each other. Each fixing seat 300 can provide stable support, thereby enhancing the structural stability of the whole trolley frame box. When part of the fixing seats 300 are damaged, only the corresponding fixing seats 300 need to be replaced.

[0116] Referring to Figures 8 to 9 In the second embodiment, the fixing holes 301 are concentrated on the same fixing seat 300, which simplifies the installation process. Meanwhile, the fixing holes 301 can be arranged as sliding rails, so that the support rods 100 can slide on the fixing seats 300 along the length direction of the chassis 20 and be connected to any one of the fixing holes 301.

[0117] In the third embodiment, the features of the first embodiment and the second embodiment can be combined to meet the diversified needs of customers.

[0118] On the basis of the first embodiment, the second embodiment and the third embodiment, the fixing seats 300 can be part of the chassis 20. That is, the fixing holes 301 are directly arranged on the chassis 20.

[0119] Referring to Figure 11 The fourth embodiment is shown.

[0120] On the basis of the first embodiment, the second embodiment and the third embodiment, the chassis 20 is provided with limiting parts 400. The limiting parts 400 correspond to the fixing holes 301 one by one, and the support rods 100 connected to the fixing holes 301 can be clamped to the limiting parts 400. The limiting parts 400 are arranged below and / or beside the fixing holes 301, and maintain a proper distance from the fixing holes 301, so that the support rods 100 can be smoothly clamped after being connected to the fixing holes 301.

[0121] The limiting parts 400 can be designed as grooves or buckles matched with the shape of the second end of the support rods 100, to ensure that the support rods 100 can be stably clamped therein. Alternatively, the limiting parts 400 are configured as a clamping tooth structure.

[0122] In the embodiment, the setting of the limiting part 400 further enhances the stability of the connection between the support rod 100 and the base frame 20. When the support rod 100 is clamped to the limiting part 400, the corresponding fixing hole 301 corresponds to the connecting hole 101 of the support rod 100, so that the fixing part can be connected. Moreover, the fixing part is not subjected to force when being connected between the support rod 100 and the fixing seat 300, facilitating the plugging and unplugging of the fixing part.

[0123] Referring to Figures 12 to 13 the fifth embodiment shown in FIG. 5.

[0124] The second end of the support rod 100 is rotatably connected to the fixing seat 300 through the second rotating shaft 120, and the length of the support rod 100 is adjustable. Optionally, at least part of the second rotating shaft 120 is configured as a bearing, a pin shaft or other rotating shaft structure. Optionally, the support rod 100 is configured as a telescopic rod.

[0125] Optionally, in the state where the body part 200 is located in the storage position, the distance between the first rotating shaft 110 and the second rotating shaft 120 is greater than or equal to the shortest length of the support rod 100. The appropriate distance can ensure the smoothness of the support rod 100 during unfolding and folding. When the body part 200 needs to be folded, a certain distance between the first rotating shaft 110 and the second rotating shaft 120 needs to be ensured to ensure that the support rod 100 can be completely stored without being squeezed or bent.

[0126] The length of the support rod 100 is different when the angle between the body part 200 and the base frame 20 is different. By adjusting the different lengths of the support rod 100 located in the supporting position, the different angles between the body part 200 and the base frame 20 are adjusted. The relative length of the support rod 100 located in the receiving position is the shortest.

[0127] When the support rod 100 is adjusted to the required length or angle, the user can fix the support rod 100 at the current position by the locking part to prevent accidental movement or deformation during use. The support rod 100 comprises a first rod 131 and a second rod 132 which are at least partially nested along the length direction, and the first rod 131 and the second rod 132 can move relatively along the length direction. One of the first rod 131 and the second rod 132 is provided with a plurality of first holes, and the other of the first rod 131 and the second rod 132 is provided with one or more second holes, and at least one first hole corresponds to a second hole to be fixed and connected by the locking part. The user can change the total length of the support rod 100 by changing the relative position between the first rod 131 and the second rod 132, so as to meet different transfer requirements. Specifically, appropriate hole positions can be selected for fixation according to actual needs, and the adjustment and fixation of the support rod 100 can be realized by fixing and connecting the first hole and the second hole by using the locking part. The type of the locking part includes but is not limited to bolts and pin shafts.

[0128] On the basis of the above embodiment, the main body 200 is provided with a support base 500 , and the support rod 100 is rotatably connected to the support base 500 via the first rotating shaft 110 .

[0129] Optionally, refer to Figure 14 The first rotating shaft 110 is located on the side of the main body 200 facing away from the base frame 20. Specifically, the support base 500 is located on the side of the main body 200 facing away from the base frame 20 and extends in a direction away from the base frame 20. The first rotating shaft 110 is connected to the support base 500. When the first rotating shaft 110 is located on the side of the main body 200 facing away from the base frame 20, the support rod 100 in the storage position is located above the main body 200, thereby facilitating the storage of the main body 200. In addition, the main body 200 in the folded position can directly abut against the base frame 20 without being interfered with by the support base 500, thereby facilitating the folding of the main body 200.

[0130] Optionally, refer to Figure 15 The first rotating shaft 110 is located on the side of the main body 200 facing the bottom frame 20. Specifically, the support base 500 is located on the side of the main body 200 facing the bottom frame 20 and extends toward the bottom frame 20. The first rotating shaft 110 is connected to the support base 500. Placing the first rotating shaft 110 on the side of the main body 200 facing the bottom frame 20 can reduce interference with surrounding structures.

[0131] Optionally, refer to Figure 16 The first rotating shaft 110 is located on both sides of the body 200 along the width direction. In this embodiment, the support base 500 can be omitted, and the first rotating shaft 110 can be directly connected to the side beam of the body 200. Alternatively, the support base 500 can be set on the side beam of the body 200, and the first rotating shaft 110 is connected to the support base 500. The first rotating shaft 110 allows the support rod 100 to rotate and adjust within a wider range, providing greater flexibility during support and storage.
