[0038] See Figure 1 and Figure 2 This application provides a carrier for carrying an axle housing. The carrier may include a base 100, a support rod 200, and positioning blocks 300. The positioning blocks 300 are used to support and limit the axle housing, and various types of positioning blocks 300 are provided to correspond to axle housings of various sizes or models. The positioning blocks 300 are detachably mounted on the support rod 200 so that different positioning blocks 300 can be mounted on the support rod 200, thereby limiting different axle housings on the carrier.

[0039] In some embodiments, the outer contour of the base 100 is rectangular. Specifically, the base 100 includes two horizontal beams 110 and two vertical beams 120, which are connected end to end in an alternating manner to form a rectangular frame structure.

[0040] In some other embodiments, a connecting beam 130 is provided between the two longitudinal beams 120. The extending direction of the connecting beam 130 is parallel to the extending direction of the transverse beam 110, and both ends of the connecting beam 130 are fixed to the longitudinal beams 120 respectively.

[0041] In one embodiment, the extension direction of the connecting beam 130 is parallel to the extension direction of the longitudinal beam 120, and both ends of the connecting beam 130 are fixed to the transverse beam 110.

[0042] In one specific embodiment, there are multiple connecting rods, which are interlaced with each other. The two ends of some connecting rods are connected to two crossbeams 110, and the two ends of some connecting rods are connected to two longitudinal beams 120.

[0043] In some embodiments, a support plate 140 is also provided on the base 100, and the peripheral edge of the support plate 140 is connected to the longitudinal beam 120, the transverse beam 110 or the connecting beam 130.

[0044] In some embodiments, the support rod 200 is fixed to the upper surface of the base 100 and is higher than the upper surface of the base 100. A protruding support column 150 is formed on the upper surface of the base 100, and the support column 150 supports the bottom end of the support rod 200, so that the support rod 200 is higher than the upper surface of the base 100. The support columns 150 are spaced apart on the bottom surface of the support rod 200, so that there is a gap between the bottom of the support rod 200 and the upper surface of the base 100.

[0045] Multiple support rods 200 are provided, spaced apart along a first direction, and extending along a second direction; both the first and second directions are located in a horizontal plane, with the first direction perpendicular to the second direction. The support rods 200 are fixed to the crossbeam 110, the longitudinal beam 120, or the connecting beam 130.

[0046] The support rods 200 are provided in different quantities, such as two, three, or four. In some embodiments, the support rods 200 are provided in three quantities.

[0047] Figure 3 This is a schematic diagram of the connection of the positioning block of this utility model on the support rod. Figure 4 This is a schematic diagram of the structure of one embodiment of the positioning block of this utility model.

[0048] See Figures 1 to 4 The positioning block 300 is fixed to the upper surface of the support rod 200; the positioning block 300 is provided with a locking position 310 for supporting and limiting the axle housing. Multiple support rods 200 are provided, spaced apart along a first direction, with the locking positions 310 on adjacent support rods 200 facing each other, so that the axle housing can be supported and limited between the locking positions 310 of the positioning blocks 300 on adjacent support rods 200, limiting the movement of the axle housing in the first and second directions, thereby limiting the axle housing on the vehicle.

[0049] The support rod 200 extends along a second direction, and multiple engagement positions 310 are spaced apart along the length of the support rod 200, thereby enabling multiple axle housings to be placed in the second direction. The support rods 200 are spaced apart along a first direction, and the axle housing is located between two adjacent support rods 200 in the first direction.

[0050] In one embodiment, the support rods 200 are configured as two in a first direction, and the axle housing can be configured as a row on the vehicle.

[0051] In another embodiment, three support rods 200 are provided along the first direction, and axle housings can be provided between two adjacent support rods 200, with two rows of axle housings provided.

[0052] In other embodiments, four support rods 200 are provided, and axle housings can be provided between two adjacent support rods 200, with three rows of axle housings provided.

[0053] The positioning block 300 includes a base plate 301, a vertical plate 302, and two side plates 303. The base plate 301 and the two side plates 303 are vertically connected to the base plate 301, and the two side plates 303 are spaced apart along a second direction. A locking position 310 is formed between the upper surface of the base plate 301, the two side plates 303, and the vertical plate 302. The vertical plate 302 extends along the second direction, and the two side plates 303 extend along a first direction.

[0054] The relative structure of the axle housing is supported on the base plate 301, and the vertical plate 302 and the two side plates 303 respectively abut against the relative positions of the axle housing.

[0055] In one embodiment, a locking position 310 is formed on a positioning block 300. In some embodiments, a positioning block 300 has a plurality of spaced locking positions 310 formed in a second direction.

[0056] In some embodiments, the positioning block 300 is provided with engagement positions 310 on both sides in the first direction.

[0057] In one specific embodiment, a locking position 310 is provided on one side of the positioning block 300 on the support rod 200 located at both ends of the first direction. Locking positions 310 are provided on both sides of the positioning block 300 on the support rod 200 located in the middle of the first direction.

[0058] In some embodiments, the positioning block 300 is detachably mounted on the support rod 200 so that different positioning blocks 300 can be mounted on the support rod 200; the size of the engaging position 310 on the different positioning blocks 300 is different, so that axle boxes of different sizes can be limited on the vehicle, reducing the vehicle's idle rate and the number of vehicles used, thereby saving space and cost.

[0059] When different sizes of axle housings need to be placed on the vehicle, only the corresponding positioning block 300 needs to be replaced. This eliminates the need to redesign and manufacture the entire vehicle, saving costs.

[0060] In the existing technology, the containers used for packaging axle boxes are generally made of paper or wood. Paper or wood packaging cannot be reused multiple times, resulting in serious waste and environmental pollution.

[0061] In this application, both the base 100 and the support rod 200 are constructed of metal materials, such as steel. The steel structure effectively ensures the reusability of the vehicle, thus reducing waste.

[0062] In some embodiments, a through-hole 304 is provided on the base plate 301, and a fastener (not shown in the figure) is provided between the base plate 301 and the support rod 200; the fastener is detachably inserted between the fixing hole 304 and the support rod 200, so that the positioning block 300 is detachably fixed to the upper surface of the support plate 140. The fastener is a bolt, which is detachably connected between the support plate 140 and the positioning block 300.

[0063] In one embodiment, the fixing hole 304 is a countersunk hole, and the upper end of the fastener does not extend beyond the upper surface of the base plate 301. The fastener setting does not affect the placement of the axle housing on the base plate 301.

[0064] In other embodiments, the positioning block 300 is detachably engaged with the support plate 140 by means of a hook or other structure.

[0065] In some embodiments, a reinforcing plate 210 is provided on the support rod 200 on the outside of the positioning block 300 to enhance the structural strength and stability of the positioning block.

[0066] In one embodiment, the positioning block 300 is a structure made of silicone, foam, or polyurethane.

[0067] See Figure 1 and Figure 2 The upper surface of the base 100 is also provided with a support rod 400, which extends in a second direction; the support rod 400 is located between two support rods 200 in a first direction to support the bottom of the axle housing. Both the support rod 400 and the positioning block 300 can support the axle housing, distribute the stress of the axle housing, and thus protect the positioning block 300.

[0068] The upper end of the support rod 400 is higher than the upper surface of the base 100 so as to effectively prevent the bottom surface of the axle housing from interfering with the upper surface of the base 100 when supporting the axle housing, thereby protecting the axle housing and the base 100.

[0069] In some embodiments, two support rods 400 are symmetrically arranged between two adjacent support rods 200, so that when the axle box is horizontally flipped, the support rods 400 can still support the corresponding position on the axle box.

[0070] Figure 5 This is a schematic diagram of the carrier when the column of this utility model is in the storage state. Figure 6 This is a structural diagram of the column of this utility model when it is in a vertical position. Figure 7 This is a structural diagram of the column of this utility model when it is in the storage state. Figure 8 This is a schematic diagram of the corner post structure of this utility model. Figure 9 This is a structural schematic diagram of the column of this utility model.

[0071] See Figures 5 to 9 The carrier also includes a column 500, which is vertically positioned. The column 500 can switch between a vertical state and a retracted state. When the column 500 is in the vertical state, it is vertically positioned. When the column 500 is in the retracted state, it is folded onto the base 100.

[0072] When the vehicle is stowed, the column 500 is in a stowed state, the vehicle has a smaller thickness in the vertical direction, and the vehicle occupies less space, which facilitates the transportation and storage of the vehicle itself.

[0073] In one embodiment, multiple columns 500 are provided, spaced apart, and the positioning block 300 is located within the enclosure of the multiple columns 500 on a horizontal plane. When the columns 500 are in the vertical position, they are used to protect the axle housing on the vehicle.

[0074] In some embodiments, the upper surface of the base 100 is further provided with a plurality of protruding corner posts 600; the plurality of corner posts 600 are arranged at intervals, and the positioning block 300 is located within the enclosed area of ​​the plurality of corner posts 600 on the horizontal plane. A column 500 is rotatably connected to the corner post 600, and the lower end of the column 500 is rotatably connected to the corner post 600, so as to be able to switch between an upright state and a retracted state. The number of corner posts 600 corresponds to the number of columns 500.

[0075] In one embodiment, the outer frame of the base 100 is rectangular; four columns 500 are provided; the four columns 500 are located at the corners of the base 100.

[0076] In some embodiments, the upper end of the corner post 600 is provided with a downwardly extending through hole 630, and the through hole 630 is open on at least one side in a first direction or a second direction; the lower end of the column 500 passes through the through hole 630 and is rotatably connected to the corner post 600.

[0077] In one embodiment, the opposing faces of two corner posts 600 facing each other along a first direction are open, i.e., the perforation 630 is open on one side of the first direction, so that the post 500 can rotate in the first direction.

[0078] In one specific embodiment, the two outermost support rods 200 in the first direction extend to both ends of the base 100 in the first direction, respectively. The column 500 is rotatable in the first direction to prevent the column 500 from interfering with the support rods 200 after being stored.

[0079] In some embodiments, the corner post 600 is provided with a horizontally extending pivot (not shown in the figure), which passes through the lower end of the upright post 500, thereby allowing the upright post 500 to rotate relative to the corner post 600. The pivot extends in a first direction or a second direction; when the pivot extends in the first direction, the upright post 500 can rotate in the second direction. When the pivot extends in the second direction, the upright post 500 can rotate in the first direction.

[0080] In one embodiment, a limiting hole 610 is provided on the upper part of the corner post 600, and the rotating shaft passes through the limiting hole 610.

[0081] In some embodiments, the column 500 has an elongated hole 510 extending vertically; the rotating shaft is rotatably inserted in the elongated hole 510 and can move relative to the column 500 along the length direction of the elongated hole 510, so that the column 500 can rotate relative to the corner post 600.

[0082] In some embodiments, a limiting groove 620 is provided at the upper end of the corner post 600; a limiting protrusion 520 protruding in a first direction is formed on the outer periphery of the column 500; the limiting protrusion 520 can be limited within the limiting groove 620 to restrict the rotation of the column 500.

[0083] When it is necessary to rotate the column 500 from the vertical position to the retracted position, move the column 500 upward. The elongated hole 510 on the column 500 moves upward relative to the rotating axis. At the same time, the limiting protrusion 520 moves upward with the column 500 and disengages from the limiting groove 620. Then rotate the column 500 to rotate it to the retracted position.

[0084] See Figure 1 and Figure 5 In this application, the vehicle is still provided with lifting lugs 700, which are located on the outer periphery of the base 100 or on the outer side of the corner post 600; multiple lifting lugs 700 are provided to facilitate lifting the vehicle.

[0085] Based on the above structure, the positioning block 300 is fixed to the upper surface of the support rod 200, and the positioning block 300 is provided with a locking position 310. The locking positions 310 on adjacent support rods 200 are arranged opposite to each other, so as to support and limit the axle housing between the locking positions 310 of the positioning blocks 300 on adjacent support rods 200, thereby limiting the movement of the axle housing in the first and second directions, so as to enable the axle housing to be carried on the vehicle. Multiple locking positions 310 are arranged at intervals along the length direction of the support rod 200, so that multiple axle housings can be placed on the vehicle at the same time.
