Description

Technical Field

[0001] This utility model relates to the technical field of workshop equipment, and more specifically, to a logistics trolley for exterior parts. Background Technology

[0002] With the continuous development of the automotive industry, car models are constantly changing, and the shapes of their exterior parts are becoming more diverse and complex, leading to a diversification of storage methods for these parts. Within automotive production workshops, exterior parts require the use of specialized logistics trolleys for transport between multiple production lines to complete assembly, quality inspection, and other processes. The positioning and placement of these exterior parts on the logistics trolleys must be carefully controlled to prevent them from exceeding their designated dimensions or falling off, thus avoiding safety hazards.

[0003] Currently, although some general-purpose logistics trolleys can be used to deliver more than one type of exterior parts, for exterior parts that differ significantly in appearance, such as the middle section of the tailgate outer panel and the rear license plate part of a car, they are still mostly delivered using corresponding types of logistics trolleys. The storage capacity of the logistics trolleys is limited, and the positioning positions on both sides of the logistics trolleys are also relatively simple and fixed. As a result, when loading exterior parts, it is necessary to align the positioning positions on both sides, resulting in low loading efficiency. Utility Model Content

A first placement mechanism and a second placement mechanism are stacked on both sides of the frame, and the first placement mechanism and the second placement mechanism are correspondingly arranged. The first placement mechanism is provided with a coarse positioning structure, and the second placement mechanism is provided with a fine positioning structure. When the logistics trolley is in working state, the distance between the placement ends of the first placement mechanism and the second placement mechanism is less than the distance between the positioning ends of the coarse positioning structure and the fine positioning structure.

[0021] Example 1 like Figures 1 to 6 The first embodiment of the present invention is a logistics trolley for appearance parts, including a frame 100. A first placement mechanism 200 and a second placement mechanism 300 are respectively stacked on both sides of the frame 100, and the first placement mechanism 200 and the second placement mechanism 300 are correspondingly arranged. A coarse positioning structure 400 is provided at the first placement mechanism 200, and a fine positioning structure 500 is provided at the second placement mechanism 300. When the logistics trolley is in working state, the distance between the placement ends of the first placement mechanism 200 and the second placement mechanism 300 is less than the distance between the positioning ends of the coarse positioning structure 400 and the fine positioning structure 500.

[0022] The stacked first placement mechanism 200 and second placement mechanism 300 enable the logistics trolley to deliver exterior parts 900 in batches. The coarse positioning structure 400 is used for coarse positioning of the exterior parts 900 on one side of the logistics trolley. Combined with the fine positioning structure 500 on the other side of the logistics trolley, this ensures the exterior parts 900 are stably placed on the trolley and improves loading efficiency. The spacing between the first placement mechanism 200 and the second placement mechanism 300, and the spacing between the coarse positioning structure 400 and the fine positioning structure 500, allows for the adaptation of common locations for the exterior parts 900, enabling the logistics trolley to hold more than one type of exterior part 900 and improving its versatility. It should be noted that the fine positioning function of the fine positioning structure 500 is relative to the coarse positioning function of the coarse positioning structure 400. This invention can be used for the logistics delivery of mid-section parts of the tailgate outer panel of SUV models and rear license plate parts of sedans.

[0023] like Figure 1 and Figure 5 As shown, the frame 100 includes a base frame 110, a first side frame 120 and a second side frame 130 respectively connected to the left and right sides of the base frame 110. A first placement mechanism 200 and a coarse positioning structure 400 are both installed on the first side frame 120, and a second placement mechanism 300 and a fine positioning structure 500 are both installed on the second side frame 130. The base frame 110 is provided with a grid structure 140. The first side frame 120 and the second side frame 130 are connected by a connecting component 150, which is provided with an information display board 800. The grid structure 140 facilitates the stepping of workers. In this embodiment, the first placement mechanism 200 is provided with at least two layers on the first side frame 120. The specific number of layers can be selected according to the actual use scenario. Preferably, it is provided with three layers. Each first placement mechanism 200 is provided with a coarse positioning structure 400 above it. The second placement mechanism 300 is also provided with the same number of layers as the first placement mechanism 200, and each second placement mechanism 300 is provided with a fine positioning structure 500 above it.

[0024] In this embodiment, the distance between the placement ends of the first placement mechanism 200 and the second placement mechanism 300 is the distance in the first direction; the distance between the positioning ends of the coarse positioning structure 400 and the fine positioning structure 500 is also the distance in the first direction. It should be noted that the first direction is the direction in which the appearance parts logistics trolley extends left and right. Furthermore, one or more of the first placement mechanism 200 can be provided along the second direction, and the specific number can be selected according to the actual usage scenario. Preferably, two are provided. It should be noted that the second direction is the direction in which the appearance parts logistics trolley extends forward and backward, and the second direction is perpendicular to the first direction.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the coarse positioning structure 400 includes a first mounting base 410 and a first bracket 430. The positioning end of the coarse positioning structure 400 includes an array of soft columnar structures 420 connected to the first mounting base 410. The soft columnar structures 420 are located obliquely above the placement end of the first placement mechanism 200. The first mounting base 410 is a strip-shaped mounting base extending along a second direction, and the soft columnar structure 420 is a polyurethane columnar structure, which can be used for coarse positioning of the appearance part 900. Figure 1 and Figure 2As shown, to improve the support strength of the first bracket 430, one or more reinforcing rods can be provided on the first bracket 430 along the second direction. In this embodiment, the upper end of the first bracket 430 is rotatably connected to the first mounting base 410 via a rotating piece 411. The rotation axis of the rotating piece 411 extends along the second direction, allowing the soft columnar structure 420 to rotate closer to or away from the placement end of the first placement mechanism 200; the lower end of the first bracket 430 is connected to the first placement mechanism 200. Figure 2 and Figure 4 As shown, to prevent the first mounting base 410 from rotating excessively, the first bracket 430 is connected to a first limiting member 440 for rotational limitation. When the first mounting base 410 rotates to contact the first limiting member 440, the columnar extension direction of the soft columnar structure 420 faces the fine positioning structure 500. Specifically, its columnar extension direction is parallel or approximately parallel to the first direction. At this time, the soft columnar structure 420 can contact one end of the appearance part 900, reducing the possibility of slippage of the appearance part 900 and achieving coarse positioning. In this embodiment, the first limiting member 440 is a first limiting block.

[0026] like Figure 2 and Figure 4 As shown, to prevent the first mounting base 410 from jumping during the forklift transport process, a locking structure 450 is provided between the first mounting base 410 and the first bracket 430. The locking structure 450 includes a fixed base 451 and a locking member 452. The locking member 452 is slidably connected to the fixed base 451, and the fixed base 451 is connected to the top of the first bracket 430. When the locking member 452 slides to protrude from the fixed base 451, the protruding end of the locking member 452 can be used to limit the first mounting base 410.

[0027] In this embodiment, the locking member 452 includes a locking post, and the fixing seat 451 includes a sleeve extending along a second direction. The locking post is slidably connected inside the sleeve. When the locking post slides until its first end protrudes from the sleeve, the first mounting seat 410 is restricted between the locking post and the first limiting member 440, thus achieving a locking function. To improve the convenience of locking and unlocking operations of the locking structure 450, an elastic element is provided between the locking post and the sleeve. The elastic element is a spring provided between the locking post and the sleeve, and a handle 453 is connected to the second end of the locking post. The handle 453 is angled relative to the locking post. Specifically, the locking post can also rotate relative to the sleeve; a notch structure is provided at the end of the sleeve near the handle 453 for the handle 453 to enter or exit. Figure 2The diagram shows the locked state of the locking structure 450. In the locked state, the handle 453 is located within the notch structure, and the locking pin extends out of the sleeve. At this time, the spring is in its original length. When unlocking is required, the handle 453 is disengaged from the notch structure, causing the locking pin to retract into the sleeve. At this time, the spring is compressed. Then, the handle 453 is rotated to engage with the outer end of the sleeve, and the locking structure 450 maintains its current unlocked state. When relocking is required, the handle 453 is rotated back to the position of the notch structure. Due to the spring force, the locking pin can quickly extend, improving the convenience of the locking operation.

[0028] like Figure 5 and Figure 6 As shown, the precision positioning structure 500 includes a second bracket 510, and the positioning end of the precision positioning structure 500 includes a third spacer 520. The upper end of the second bracket 510 is connected to a third mounting groove 530, and the third spacer 520 is installed in the third mounting groove 530, and the third spacer 520 is located diagonally above the placement end of the second placement mechanism 300. Figure 6 As shown, to improve the support strength of the second bracket 510, one or more reinforcing rods can be provided on the second bracket 510 along the second direction. In this embodiment, the third spacer 520 extends along the second direction. The third spacer 520 is a third polyurethane spacer. The third polyurethane spacer has multiple recesses along the second direction. The openings of the recesses face the inside of the logistics trolley. These recesses can be used to snap onto the other end of an exterior part 900 to achieve precise positioning.

[0029] It should be noted that, in extracting the storage and positioning points of the exterior parts 900 that need to be distributed through logistics, in this embodiment, the storage and positioning points of the middle section of the tailgate outer panel of the SUV model and the rear license plate parts of the sedan are extracted to obtain universal points that can be used to adapt to the exterior parts 900. As a result, the third partition 520 is located diagonally above the placement end of the second placement mechanism 300, and the soft columnar structure 420 is located diagonally above the placement end of the first placement mechanism 200. This allows the logistics trolley to be applicable to more than one type of exterior part 900, improving the versatility of the logistics trolley.

[0030] It should be noted that, as Figure 6 As shown, in the precision positioning structure 500 located at the top layer, there is a spare space at one end of the third mounting slot 530 near the rear of the logistics trolley, that is, the third partition 520 will not fill the entire third mounting slot 530. This setting can prevent operators from touching other appearance parts 900 placed on the logistics trolley when picking up appearance parts 900 near the rear. It conforms to ergonomic design and can also protect the quality of the parts.

[0031] The working principle of a logistics trolley for exterior parts in this embodiment is as follows: With the coarse positioning structure 400 in the open state, that is, the soft columnar structure 420 is rotated to face outward; then, the outer part 900 is placed on the placement end of the first placement mechanism 200 and the second placement mechanism 300, so that the bottom of the outer part 900 is limited; then, one end of the outer part 900 is clamped to the third spacer 520, and so on, until all the recesses on the third spacer 520 of the fine positioning structure 500 are filled, the coarse positioning structure 400 is rotated again so that the soft columnar structure 420 contacts the other end of each outer part 900, and is locked by the locking structure 450 to complete the placement; since the other end of the outer part 900 does not need to be clamped by the recesses one by one, the assembly efficiency can be improved.

[0032] Example 2 This embodiment is a second embodiment of a logistics trolley for exterior parts. This embodiment is similar to the first embodiment, except that, as shown in the following... Figures 3 to 7 As shown, the first placement mechanism 200 includes a first movable frame 210, and the placement end of the first placement mechanism 200 includes a first spacer 220. One end of the first movable frame 210 is rotatably connected to the first side frame 120 via a first rotating shaft 211, and the other end is connected to a first mounting groove 240. The first spacer 220 is installed in the first mounting groove 240. The second placement mechanism 300 includes a second movable frame 310, and the placement end of the second placement mechanism 300 includes a second spacer 320. One end of the second movable frame 310 is rotatably connected to the second side frame 130 via a second rotating shaft 311, and the other end is connected to a second mounting groove 340. The second spacer 320 is installed in the second mounting groove 340.

[0033] In this embodiment, the rotation axis directions of the first rotating shaft 211 and the second rotating shaft 311 both extend along the second direction, so that the first movable frame 210 and its first partition 220 and coarse positioning structure 400 can rotate toward the outside or inside of the logistics trolley, and also so that the second movable frame 310 and its second partition 320 and fine positioning structure 500 can rotate toward the outside or inside of the logistics trolley, which facilitates the stacking of the appearance parts 900 on the logistics trolley.

[0034] In this embodiment, both the first spacer 220 and the second spacer 320 extend along the second direction. The first spacer 220 is a first polyurethane spacer, and the second spacer 320 is a second polyurethane spacer. Both the first and second polyurethane spacers have multiple recesses along the second direction, and the recesses on the first and second polyurethane spacers are arranged in a one-to-one correspondence. The recesses on both can be used to engage the bottom of the appearance part 900, achieving stable placement. In this embodiment, the recesses on the second and third polyurethane spacers are also arranged in a one-to-one correspondence. However, it should be noted that this one-to-one correspondence can be a correspondence located in the same vertical plane, or it can be staggered to a certain extent according to the curvature of the appearance part 900. However, the correspondence between the recesses facilitates the stable placement of the appearance part 900.

[0035] like Figures 4 to 6 As shown, the first side frame 120 is connected to a second limiting member 230 for rotational limitation, and the second side frame 130 is connected to a third limiting member 330 for rotational limitation. When the first movable frame 210 and the second movable frame 310 are in contact with the second limiting member 230 and the third limiting member 330 respectively, the distance between the first spacer 220 and the second spacer 320 is less than the distance between the positioning ends of the coarse positioning structure 400 and the fine positioning structure 500. Specifically, when the first movable frame 210 rotates to its bottom contact with the second limiting member 230, the openings of the recesses of the first spacer 220 are all facing upwards; when the second movable frame 310 rotates to its bottom contact with the third limiting member 330, the openings of the recesses of the second spacer 320 are all facing upwards, which can be used for placing the appearance parts 900. In this embodiment, the second limiting member 230 is a second limiting block connected to the inner side of the first side frame 120, and the third limiting member 330 is a third limiting block connected to the inner side of the second side frame 130.

[0036] like Figures 1 to 6 As shown, the lower end of the first bracket 430 is connected to the first movable frame 210, and the first spacer 220 is located diagonally below the flexible columnar structure 420; the lower end of the second bracket 510 is connected to the second movable frame 310, and the second spacer 320 is located diagonally below the third spacer 520; in the first direction, the distance between the first spacer 220 and the second spacer 320 is smaller than the distance between the flexible columnar structure 420 and the third spacer 520, which can accommodate the common positions of the appearance parts 900.

[0037] like Figure 3 and Figure 6 As shown, in order to improve the support strength of the first movable frame 210 and the second movable frame 310, one or more reinforcing rods can be installed on the first movable frame 210 along the second direction, and one or more reinforcing rods can also be installed on the second movable frame 310 along the second direction.

[0038] It should be noted that, as Figure 3 and Figure 6 As shown, in the first placement mechanism 200 and the second placement mechanism 300 located at the top layer, there is a spare space at one end of the first mounting slot 240 and the second mounting slot 340 near the rear side of the logistics trolley. That is, the first partition 220 will not fill the entire first mounting slot 240, and the second partition 320 will not fill the entire second mounting slot 340. This arrangement can prevent the operator from touching other appearance parts 900 placed on the logistics trolley when picking up the appearance parts 900 near the rear side. It conforms to ergonomic design and can also protect the quality of the parts.

[0039] The working principle of a logistics trolley for exterior parts in this embodiment is as follows: The first placement mechanism 200 and the second placement mechanism 300 are rotated toward the inside of the logistics trolley, so that the first movable frame contacts the second limiting member 230 and the second movable frame 310 contacts the third limiting member 330. At the same time, the coarse positioning structure 400 is opened. Next, the outer part 900 is placed on the first partition 220 and the second partition 320, so that the bottom of the outer part 900 has two limiting points. Then, one end of the outer part 900 is locked to the third partition 520, and so on. When the recesses on the first partition 220 and the second partition 320 are filled, the coarse positioning structure 400 is rotated so that the soft columnar structure 420 contacts the other end of each outer part 900 and is locked by the locking structure 450. At this time, each outer part 900 has four limiting points, and the outer part 900 can be stably placed on the logistics trolley. Figure 7 As shown.

[0040] It should be noted that a set of positioning and placement mechanisms is formed by configuring a first placement mechanism 200, a second placement mechanism 300, a coarse positioning structure 400, and a fine positioning structure 500 corresponding to each position. When loading parts onto the vehicle, the set of positioning and placement mechanisms to be used can be rotated to the working state, that is, the positioning and placement mechanism can be flipped inwards on the logistics trolley via the first rotating shaft 211 and the second rotating shaft 311. The remaining sets of positioning and placement mechanisms are kept in the non-working state, that is, the positioning and placement mechanisms can be flipped outwards on the logistics trolley via the first rotating shaft 211 and the second rotating shaft 311, which facilitates operation. The parts can also be placed in order from the inside to the outside and from the bottom to the top.

[0041] Example 3 This embodiment is a third embodiment of a logistics trolley for exterior parts. This embodiment is similar to Embodiment 1 or 2, except that, as Figures 3 to 7As shown, the exterior parts logistics trolley also includes a first position adjustment structure 600, and a coarse positioning structure 400 is connected to a first placement mechanism 200 through the first position adjustment structure 600. In this embodiment, it also includes a second position adjustment structure 700, and a fine positioning structure 500 is connected to a second placement mechanism 300 through the second position adjustment structure 700. The distance between the coarse positioning structure 400 and the fine positioning structure 500 can be adjusted by the first position adjustment structure 600 and the second position adjustment structure 700. The first position adjustment structure 600 and the second position adjustment structure 700 can be used to adjust the distance between the coarse positioning structure 400 and the fine positioning structure 500, which can meet the common requirements of different vehicle models.

[0042] like Figure 3 and Figure 4 As shown, the first position adjustment structure 600 includes a first sliding member 610, a first bracket 430 fixedly connected to the first sliding member 610, the first sliding member 610 slidably connected to the first movable frame 210, and a first positioning structure 620 provided between the first sliding member 610 and the first movable frame 210. Specifically, the first movable frame 210 includes two parallel extension rods, which are connected to the first side frame 120 via a first rotating shaft 211. A support rod is connected between the two extension rods, and a first spacer 220 is installed on the support rod via a first mounting groove 240. The first sliding member 610 includes a sliding groove adapted to the extension rod, which is slidably connected to the extension rod. Specifically, the first positioning structure 620 includes a positioning pin, and multiple first holes 212 are provided on the extension rod along its extension direction. The positioning pin passes through the sliding groove and is inserted into the corresponding first hole 212, thereby enabling the positioning of the first bracket 430 on the first movable frame 210.

[0043] like Figure 6 As shown, the second position adjustment structure 700 is structurally similar to or the same as the first position adjustment structure 600. The second position adjustment structure 700 includes a second sliding member 710 and a second positioning structure 720. The second movable frame 310 is also provided with a plurality of second holes 312, which are similar to or the same as those on the first movable frame 210.

[0044] The working principle of a logistics trolley for exterior parts in this embodiment is as follows: Based on the length of the appearance part 900 to be placed, the position of the coarse positioning structure 400 is adjusted by the first position adjustment structure 600, and / or the position of the fine positioning structure 500 is adjusted by the second position adjustment structure 700, so that the distance between the coarse positioning structure 400 and the fine positioning structure 500 can accommodate the appearance part 900 to be placed; then, the currently prepared set of positioning and placement mechanisms is rotated to the working state, and the coarse positioning structure 400 is in the open state, while the remaining sets of positioning and placement mechanisms... The device remains in a non-working state. Next, the exterior part 900 is placed on the first partition 220 and the second partition 320. Then, one end of the exterior part 900 is locked to the third partition 520. After the recesses on the first partition 220 and the second partition 320 of the positioning and placement mechanism are filled, the coarse positioning structure 400 is rotated so that the soft columnar structure 420 contacts the other end of each exterior part 900 and is locked by the locking structure 450. The exterior part 900 can be stably placed on the logistics trolley.
