[0036] The present application provides a turnover vehicle which can effectively prevent tilting during use, and can be conveniently stored when not in use, thereby reducing space occupation. The embodiments of the present application will be described below in conjunction with the drawings:
[0037] Referring to Figure 1 and Figure 2As shown, the utility model embodiment's turnover vehicle has the length, width and height of setting, can reference the front -back direction of the schematic in the drawing is length direction, left -right direction is width direction, up -down direction is height direction. Turnover vehicle is applicable to the transfer of goods, including base 100, rear frame 200, folding frame and first locking piece 500.
[0038] Base 100 has opposite front end 101 and rear end 102 along length direction, and the width of front end 101 is less than the width of rear end 102, and the lower portion of base 100 has overhead space;The width corresponding to rear end 102 of overhead space is greater than the width of front end 101, therefore, in some cases, the front end 101 of base 100 of turnover vehicle can be inserted into the overhead space of rear end 102 of base 100 of another turnover vehicle, and the telescoping of base 100 is realized.
[0039] Rear frame 200 is located above base 100 and is connected to rear end 102. Folding frame is located above base 100 and includes base frame 300 and front frame 400, base frame 300 is rotatably connected to base 100 and front frame 400, and folding frame can switch between use state and storage state.
[0040] Referring to Figure 1 In use state, base frame 300 is laid on the upper portion of base 100, and front frame 400 is erected on the upper portion of front end 101, so that the space between front frame 400 and rear frame 200 forms stacking space, which can be used for stacking goods to be transported. Therefore, when the turnover vehicle is used, the folding frame can be unfolded to the use state, the goods are carried on the base frame 300, and are stacked between the front frame 400 and the rear frame 200. The bottom overhead space can be used for the forklift to extend and lift, so as to realize the lifting of the goods. The front frame 400 and the rear frame 200 can abut against the side of the stacked goods, which is beneficial to prevent the stacked goods from falling. In use, the rear frame 200 can also be conveniently used as a handrail to facilitate personnel operation.
[0041] It can be understood that when the turnover vehicle of the utility model embodiment is used to transport packaged goods, the abutting action of the front frame 400 and the rear frame 200 can effectively avoid the damage caused by the collapse of the goods, and when needed, the front frame 400, the rear frame 200 and the base frame 300 and other structures can also be conveniently used for connecting and fixing the fixing members such as binding belts and ropes of the stacked goods, which can not only reduce the consumption of adhesive tape, but also effectively reduce the damage of the outer package, protect the integrity of the package appearance, and improve the user experience.
[0042] Referring to Figure 2In the storage state, the bottom frame 300 is at least partially erected between the front end 101 and the rear end 102, the front frame 400 is folded with the bottom frame 300, and the first locking member 500 is adapted to connect the bottom frame 300 and the front frame 400 to lock the relative position of the front frame 400 and the bottom frame 300 in the use state. Therefore, when the trolley is not in use, the folding frame can be folded to the storage state, the bottom frame 300 is rotated relative to the base 100, so that the bottom frame 300 is folded from the state of being laid on the base 100 to being at least partially erected above the base 100 between the front frame 400 and the rear frame 200, and the front frame 400 and the bottom frame 300 are folded. Thus, the space occupied by the folding frame is reduced, and at least the space above the front end 101 of the base 100 is left after the folding frame is folded, thereby reducing the overall volume of the trolley and facilitating storage.
[0043] In addition, in the use scenario with multiple trolleys, since the overhead space below the base 100 corresponds to a width at the rear end 102 that is greater than the width at the front end 101, the front end 101 of the trolley can extend into the overhead space from the rear end 102 of another trolley after the folding frame of the trolley is folded to the storage state, thereby achieving the nesting of the trolleys and effectively reducing the space occupied by the trolleys.
[0044] In some embodiments, the overhead space of the base 100 corresponds to a height at the rear end 102 that is greater than the height at the front end 101, thereby facilitating the front end 101 of the base 100 of the trolley to access the overhead space of another trolley from below the rear end 102, and achieving the nesting of the trolleys.
[0045] As an example, referring to Figure 3 As an example, referring to
[0046] Similarly, in the case of more trolleys, the trolleys can be nested one after another behind the rear trolley, thereby facilitating the storage of the trolleys and effectively reducing the space required by the trolleys when they are idle.
[0047] It can be understood that in the use scene of logistics transfer, a large number of turnover vehicles are usually needed to prepare for the transfer of a large number of goods, and after use, the commonly used turnover vehicles usually need to be collected and stacked one by one manually, which not only consumes a large amount of manpower, but also needs to provide a large space for the placement of the turnover vehicles. The turnover vehicle of the embodiment of the present application can effectively save the manpower and space required for the turnover vehicle arrangement. By using the turnover vehicle of the embodiment of the present application, the folding frame can be folded to the storage state after use, reducing the size of the single turnover vehicle. When a plurality of turnover vehicles need to be collected or transferred, the turnover vehicles can be stacked together through the stacking of the turnover vehicles, so that the turnover vehicles stacked together have a certain limit between them, thereby facilitating the overall transfer of a certain number of stacked turnover vehicles, saving the tedious operation of transferring each turnover vehicle one by one. The stacking of the turnover vehicles can significantly reduce the occupied area and the overall volume of the two turnover vehicles, thereby reducing the required space.
[0048] Referring to Figure 4 In some embodiments of the turnover vehicle, the bottom frame 300 can include a first bottom frame 310 and a second bottom frame 320. The first bottom frame 310 is fixedly connected to the base 100, and the rear frame 200 can be fixedly connected to the first bottom frame 310 or the rear frame 200 can be fixedly connected to the base 100. The second bottom frame 320 is rotatably connected to the first bottom frame 310 and the front frame 400. In the use state, the first bottom frame 310 and the second bottom frame 320 are laid on the upper side of the base 100, the first bottom frame 310 is located between the rear frame 200 and the second bottom frame 320, and the front frame 400 is erected on the upper side of the second bottom frame 320. Therefore, the first bottom frame 310 and the second bottom frame 320 can be used to carry the bottom of the goods, and the front frame 400, the rear frame 200, the first bottom frame 310 and the second bottom frame 320 form a stacking space for stacking goods. In the storage state, the second bottom frame 320 is folded relative to the first bottom frame 310 to lean against the rear frame 200, so that the second bottom frame 320 is erected on the upper side of the base 100, and the front frame 400 is folded with the second bottom frame 320. It can be convenient to fold and store the second bottom frame 320. The second bottom frame 320 can be erected on the upper side of the base 100 in the vertical direction, or can be inclined to the direction of the rear frame 200 relative to the vertical direction. In some embodiments, a part of the second bottom frame 320 leans against the front side of the rear frame 200, which is conducive to the second bottom frame 320 maintaining the folded state of being erected relative to the first bottom frame 310.
[0049] When switching from the use state to the storage state, the front frame 400 can be folded towards one side of the second bottom frame 320 first, and then the second bottom frame 320 is turned upwards relative to the first bottom frame 310 and leans towards the rear frame 200, so that the front frame 400 and the second bottom frame 320 are away from the space above the front end 101 of the base 100, so that the front end 101 of the base 100 can be nested with another trolley. The front side of the rear frame 200 can be connected with a buffer pad, which is used to abut between the second bottom frame 320 and the rear frame 200 when the second bottom frame 320 leans against the rear frame 200, and realizes buffering.
[0050] In some embodiments, the width of the first bottom frame 310 and the second bottom frame 320 can be greater than the maximum width of the base 100. Compared with the scheme of directly carrying articles through the base 100, the first bottom frame 310 and the second bottom frame 320 with greater width can carry larger size articles, thereby being suitable for transporting more size articles.
[0051] In some embodiments of the trolley, the bottom frame 300 further comprises an elastic member 330 connected to the first bottom frame 310 and the second bottom frame 320. The elastic member 330 is used to provide an elastic force for turning the second bottom frame 320 towards the rear frame 200. On the one hand, during the turning of the second bottom frame 320 relative to the first bottom frame 310, the elastic member 330 provides an elastic force to turn the second bottom frame 320 towards the rear frame 200, thereby improving the convenience of storage. It can be understood that the elastic member 330 can be a torsion spring, and the first bottom frame 310 and the second bottom frame 320 can be rotationally connected by a bolt. The torsion spring can be wound around the outer periphery of the bolt, one end of the torsion spring is connected to the first bottom frame 310, and the other end of the torsion spring is connected to the second bottom frame 320. When the first bottom frame 310 and the second bottom frame 320 are laid on the upper side of the base 100, the torsion spring is in a certain torsion state and has a pre-tension. When the second bottom frame 320 is turned upwards relative to the first bottom frame 310, the elastic recovery force of the torsion spring provides an elastic force to assist the second bottom frame 320 to turn towards the rear frame 200. Alternatively, the elastic member 330 can also be a tension spring, one end of the tension spring is connected to the second bottom frame 320, and the other end of the tension spring is connected to the first bottom frame 310. When the first bottom frame 310 and the second bottom frame 320 are laid on the upper side of the base 100, the tension spring is in a certain tension state. When the second bottom frame 320 is turned upwards relative to the first bottom frame 310, the elastic recovery force of the tension spring provides an elastic force to assist the second bottom frame 320 to turn towards the rear frame 200. On the other hand, in the state that the second bottom frame 320 leans against the rear frame 200, the elastic force of the elastic member 330 is also beneficial to keep the second bottom frame 320 against the rear frame 200.
[0052] In other embodiments, compared with the above-mentioned scheme that the base frame 300 comprises the first base frame 310 and the second base frame 320, the base frame 300 can also be an integral frame body, which is rotated relative to the base 100 to stand on the front side of the rear frame 200 in the storage state. For example, taking the state that the base frame 300 is laid flat above the base 100 in the use state as a reference, one end of the base frame 300 corresponding to the rear end 102 of the base 100 is rotatably connected to the base 100, one end of the base frame 300 corresponding to the front end 101 of the base 100 is rotatably connected to the front frame 400, and the front frame 400 stands above one end of the base frame 300 at the front end 101 of the base 100. In the storage state, the front frame 400 and the base frame 300 can be folded, and then the base frame 300 is rotated upward relative to the base 100 to stand above the base 100 or lean against the front side of the rear frame 200. At this time, the base frame 300 and the front frame 400 are stored on the front side of the rear frame 200, and the space above the front end 101 of the base 100 is released, so that the front end 101 of the base 100 can be nested from below the rear end 102 of another trolley.
[0053] It can be understood that in the use state, the front frame 400 stands above the base frame 300 and can be used to abut against the side of the stacked articles, and the front frame 400 is locked in the relative position with the base frame 300 by the first locking member 500, so that the front frame 400 remains in the standing position in the use state. The first locking member 500 can adopt various structural forms to achieve the locking of the standing state of the front frame 400. For example, the first locking member 500 can be a support rod structure, which abuts between the front frame 400 and the base frame 300 when the front frame 400 is unfolded relative to the base frame 300 to the standing state, so as to maintain the standing of the front frame 400. In the storage state, the first locking member 500 can be separated from abutting the front frame 400 and / or the base frame 300, so that the front frame 400 can be rotated and folded on one side of the base frame 300 relative to the base frame 300.
[0054] Alternatively, referring to Figure 5 and Figure 6 In some embodiments, the first locking member 500 can also adopt other structures. For example, the first locking member 500 can comprise a limiting column 510, a limiting block 520, and a rotating shaft. The limiting column 510 is fixedly connected to the base frame 300 and is provided with a limiting groove 511 having an opening away from the base frame 300. The limiting block 520 is fixedly connected to the front frame 400, and the front frame 400 is rotatably connected to the limiting column 510 by the rotating shaft, so as to facilitate the folding and unfolding of the front frame 400 and the base frame 300 (for example, the second base frame 320). In the use state, the limiting column 510 stands above the base frame 300, and the front frame 400 stands above the base frame 300, so that the limiting block 520 is accommodated in the limiting groove 511 and abuts against the groove wall of the limiting groove 511, so that the front frame 400 remains standing and facilitates use.
[0055] Further, referring to Figures 5 to 8 The limiting post 510 can be provided with a first connecting hole 540, and the front frame 400 is provided with a second connecting hole 450 corresponding to the position of the first connecting hole 540. The rotating shaft is inserted into the first connecting hole 540 and the second connecting hole 450 to realize the rotating connection of the front frame 400 and the limiting post 510, so that the front frame 400 can rotate relative to the bottom frame 300. The second connecting hole 450 includes a first hole section 451 and a second hole section 452 connected in communication. In the use state, the first hole section 451 is arranged to extend in the vertical direction, and the second hole section 452 is located below the first hole section 451 and extends obliquely away from the rear frame 200. Therefore, when folding, the front frame 400 can be moved upward to disengage the limiting block 520 from the opening of the limiting groove 511, and then the front frame 400 is rotated towards the upper side of the bottom frame 300 to realize folding. During the upward movement of the front frame 400, the first hole section 451 can provide a relative movement space for the rotating shaft, and during the rotation of the front frame 400 towards the bottom frame 300, the second hole section 452 can provide a relative movement space for the rotating shaft to avoid interference.
[0056] In some embodiments, referring to Figures 5 to 8 One side of the limiting block 520 is provided with a clearance cut edge 521. When the front frame 400 is moved upward to the upper end of the clearance cut edge 521 to extend out of the opening of the limiting groove 511, the front frame 400 can be rotated. During the rotation of the front frame 400 relative to the limiting post 510, the clearance cut edge 521 can draw the limiting groove 511 along the upper end edge of the limiting member, which can reduce interference. Correspondingly, the groove wall shape of the limiting groove 511 can be matched with the outer shape contour of the limiting block 520, so as to effectively limit the displacement of the limiting block 520 relative to the limiting post 510 in the forward and backward directions and downward direction, and improve the stability of limiting the front frame 400.
[0057] In some embodiments, the limiting post 510 can also be provided with a containing groove, and a part of the front frame 400 is contained in the containing groove, or the front frame 400 is provided with a containing groove, and a part of the limiting post 510 is contained in the containing groove to limit the relative position of the front frame 400 and the bottom frame 300 in the width direction.
[0058] Referring to Figure 9In some embodiments, the base 100 comprises first support rods 110, a second support rod 120, and traveling wheels 140. The two first support rods 110 are spaced apart along the width direction, and each first support rod 110 extends along the length direction. The lower side of each end of the first support rod 110 is connected with a traveling wheel 140, so that the traveling wheels 140 can support the first support rods 110 above the ground, and the first support rods 110 and the space below the plane on which the first support rods 110 are located define an overhead space. The second support rod 120 is connected to one end of the two first support rods 110 to form a front end 101 of the base 100, and the other end of the two first support rods 110 forms a rear end 102 of the base 100. The distance between the two first support rods 110 gradually increases from the front end 101 to the rear end 102. Therefore, the width of the overhead space between the two first support rods 110 gradually increases from the front end 101 to the rear end 102. The width of the front end 101 formed by the connection of the second support rod 120 to one end of the two first support rods 110 is smaller than the distance between the two first support rods 110 at the rear end 102. Therefore, the second support rod 120 and the front end 101 formed by the connection of the second support rod 120 to one end of the two first support rods 110 can enter the space below another trolley from the rear end 102 of the two first support rods 110 of the other trolley, so as to realize the telescoping of the two trolleys.
[0059] In some embodiments, the base 100 further comprises a third support rod connected to the rear end of the two first support rods 110, and the bottom of the third support rod is higher than the top of the second support rod 120. Alternatively, a rear frame 200 is connected to the rear end of the two first support rods 110, and the bottom of the rear frame 200 is higher than the top of the second support rod 120. Alternatively, a bottom frame 300 (for example, a first bottom frame 310) is connected to the rear end of the two first support rods 110, and the bottom of the bottom frame 300 is higher than the top of the second support rod 120. Therefore, the height of the overhead space at the rear end 102 is higher than the height of the front end 101 of the base 100, so that when the two trolleys are telescoped, the front end 101 of the base 100 of the trolley on the rear side can smoothly extend into the space below the base 100 from the rear end 102 of the trolley on the front side, without the need to lift the trolley on the front side, thereby facilitating the telescoping operation.
[0060] In some embodiments, a fourth support rod 130 can be connected between the two first support rods 110 to improve the support strength and facilitate the lifting by a forklift.
[0061] It can be understood that the base 100 can also adopt other structural forms, and is not limited to the form that the base 100 includes the first support rod 110, the second support rod 120 and the third support rod. For example, as an example, the base 100 can include a bottom plate, the bottom plate is connected with the traveling wheels 140 below to make the bottom plate be above the ground, the bottom plate below forms an above-ground space, the front end 101 of the bottom plate has a width smaller than that of the rear end 102, and the distance between the two traveling wheels 140 arranged below the rear end 102 of the bottom plate in the width direction is greater than the distance between the front end 101 of the bottom plate, so that the bottom plates of the two trolleys can be nested, and the front end 101 of the bottom plate of the rear trolley is nested below the rear end 102 of the bottom plate of the front trolley.
[0062] Referring to Figure 1 , Figure 2 and Figure 7 In some embodiments of the trolley, the front frame 400 can also be provided as a foldable structure, so as to further reduce the volume in the storage state. For example, the front frame 400 can include an upper frame 410, a lower frame 420 and a second locking member, the two ends of the lower frame 420 are respectively rotationally connected to the bottom frame 300 and the upper frame 410, so that the front frame 400 can be unfolded and folded, and the second locking member is suitable for connecting the upper frame 410 and the lower frame 420, and is used for locking the relative positions of the upper frame 410 and the lower frame 420 when the front frame 400 is unfolded. When folding is required, the second locking member can be separated from the upper frame 410 and the lower frame 420, and then the upper frame 410 is rotated towards the lower frame 420 to achieve folding of the two.
[0063] Specifically, for the convenience of understanding, the structure can be introduced with reference to the folding frame in the use state, one side of the lower frame 420 towards the rear frame 200 has a groove 440, and a part of the upper frame 410 is located in the groove 440, or the groove 440 can also be arranged on the side of the upper frame 410 towards the rear frame 200, and a part of the lower frame 420 is located in the groove 440. The lower frame 420 is rotationally connected to the lower frame 420, and corresponding positions above or below the rotational connection of the upper frame 410 and the lower frame 420 are respectively provided with limiting holes. When the upper frame 410 and the lower frame 420 are in the unfolded state, the positions of the limiting holes of the upper frame 410 and the lower frame 420 correspond, and the second locking member can be a columnar structure such as a bolt. The second locking member is inserted into the limiting hole, and the relative rotation of the upper frame 410 and the lower frame 420 can be limited, so as to maintain the unfolded state of the upper frame 410 and the lower frame 420. When folding is required, the second locking member can be pulled out of the limiting hole, and the upper frame 410 can be rotated relative to the lower frame 420 towards the rear frame 200, so as to be folded on the inner side of the lower frame 420.
[0064] Alternatively, the lower frame 420 has a groove 440 on the side facing away from the rear frame 200, and a portion of the upper frame 410 is located in the groove 440, or alternatively, the groove 440 can be provided on the side of the upper frame 410 facing away from the rear frame 200, and a portion of the lower frame 420 is located in the groove 440. The upper frame 410 and the lower frame 420 are rotationally connected, and the upper frame 410 and the lower frame 420 are respectively provided with limiting holes at positions above or below the rotational connection. When the upper frame 410 and the lower frame 420 are in the unfolded state, the limiting holes of the upper frame 410 and the lower frame 420 are in corresponding positions, and a second locking member is inserted into the limiting holes to limit the relative rotation of the upper frame 410 and the lower frame 420, thereby maintaining the unfolded state of the upper frame 410 and the lower frame 420. When folding is required, the second locking member is simply pulled out of the limiting hole, and the upper frame 410 is rotated relative to the lower frame 420 away from the rear frame 200, thereby being folded on the outside of the lower frame 420.
[0065] Referring to Figure 1 In some embodiments, the turnover vehicle further comprises a module belt 600, which is arranged above the base frame 300 in the use state and is used to carry the articles to be transported. The module belt 600 comprises a body and a plurality of rollers. The body is fixed to the base frame 300, and the rollers are in rolling contact with the articles carried above, thereby facilitating the feeding and discharging of the articles and reducing the damage to the packaging caused by friction.
[0066] The turnover vehicle of the embodiments of the present application can be applied to the transportation of various articles, and is particularly suitable for the transportation of large articles, such as televisions, air conditioners and other household appliances, and can effectively reduce the probability of damage caused by the collapse of the articles. The turnover vehicle of the embodiments of the present application is also particularly suitable for the transportation of packaged articles, and can effectively protect the integrity of the outer packaging of the articles, thereby improving the user experience. When idle, a plurality of turnover vehicles can be nested for storage, thereby reducing the occupation of the site.
[0067] The embodiments of the present application have been described in detail above with reference to the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
