Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0019] Example 1 like Figures 1 to 4As shown, a multi-purpose trailer of this embodiment includes a folding vehicle body 1 and a sunshade bracket 2.
[0020] The folding vehicle body 1 includes a bottom support 11, side supports 12, and wheels 13. The wheels 13 are provided at the bottom of the bottom support 11, and the side supports 12 are provided on at least three sides above the bottom support 11. The bottom support 11 and at least one side support 12 are foldable structures and can all be folded in the same direction to reduce the overall volume of the folding vehicle body 1, making it convenient for transportation and storage.
[0021] The sunshade bracket 2 includes two folding support rods 21, which are respectively disposed above the two uprights 120 on both sides of the foldable side bracket 12. In this embodiment, the folding support rods 21 are disposed at the top of the uprights 120. The folding support rods 21 can be unfolded above the bottom bracket 11 or folded to the outside of the two uprights 120. A sunshade cloth (not shown) is connected between the two folding support rods 21.
[0022] Therefore, by setting two folding support rods 21, the folding support rods 21 can be folded up and down simultaneously after the folding vehicle body 1 is folded up. When the folding support rods 21 are opened, the sunshade can be opened at the same time to facilitate sun protection or rain protection.
[0023] Specifically, such as Figure 1 and Figure 2 The folding support 21 in this embodiment includes a vertical rod 211, a horizontal rod 212, and a diagonal rod 213.
[0024] When the folding support rod 21 is unfolded, the horizontal bar 212 can extend horizontally above the bottom support 11, the vertical bar 211 extends vertically, the upper end of the vertical bar 211 is hinged to the rear of the horizontal bar 212 near the upright 120, the lower end of the vertical bar 211 can be bent backward and fitted with a connecting seat 214, the connecting seat 214 is hinged to the top of the upright 120 and the rear side of the connecting seat 214 has a "C"-shaped fastening groove 2141, the diagonal bar 213 is located behind the vertical bar 211, the top of the diagonal bar 213 extends diagonally backward, the upper end of the diagonal bar 213 is hinged to the rear end of the horizontal bar 212 and is spaced behind the vertical bar 211, the lower part of the diagonal bar 213 is detachably fastened to the fastening groove 2141, and the lower end of the diagonal bar 213 is hinged to the top of the upright 120 and is spaced below the connecting seat 214.
[0025] Therefore, a triangular support structure can be formed by the rear of the vertical rod 211, the diagonal rod 213 and the horizontal rod 212, which can stably support the horizontal rod 212. A sunshade structure such as canvas or tarpaulin can be laid between the horizontal rods 212 of the two folding support rods 21, thus forming the top sunshade of the folding vehicle body 1, which can provide sun protection for people and objects inside the vehicle, and also has a rainproof function.
[0026] Furthermore, see Figure 3 and Figure 4 The two folding support rods 21 can be folded and folded together with the folding vehicle body 1. When the folding vehicle body 1 is folded, the bottom bracket 11 and the uprights 120 on both sides of the foldable side bracket 12 come closer to fold, which can bring the two folding support rods 21 closer to fold. The rear end of the horizontal bar 212 of the folding support rod 21 can be rotated downward under force, and the lower part of the diagonal bar 213 will automatically separate from the buckle 2141 of the lower end connecting seat 214 of the vertical bar 211. Finally, the horizontal bar 212, the diagonal bar 213 and the vertical bar 211 can all rotate and fold to the outside of the upright 120. The unfolding and folding of the folding support rod 21 is relatively convenient, and the folding support rod 21 can be folded together with the sunshade cloth.
[0027] In this embodiment, when unfolded, the lower part of the diagonal rod 213 is fastened and fixed to the slot 2141 of the connecting seat 214, which enables the connection and cooperation between the lower part of the diagonal rod 213 and the lower end of the vertical rod 211, thereby supporting the horizontal rod 212. When folded, the lower part of the diagonal rod 213 can automatically separate from the slot 2141, making it convenient to use. Of course, the lower part of the diagonal rod 213 can also be connected to the lower end of the vertical rod 211 through other structures, such as positioning pins, hooks, or other detachable locking connection structures, all of which can achieve the effect of the diagonal plate 213 and the vertical rod 211 simultaneously supporting the horizontal rod 212.
[0028] In this embodiment, when the folding support rod 21 is unfolded, the horizontal bar 212 is roughly horizontal, but it can also be set slightly inclined; and the lower end of the vertical bar 211 is connected to the connecting seat 214 after being bent, or it can be directly connected to the connecting seat 214 without being bent.
[0029] In this embodiment, the sunshade bracket 2 may further include a folding central rod 22; the folding central rod 22 includes two sub-rods 221 and a hinge seat 222. The two sub-rods 221 are hinged together by the hinge seat 222. The ends of the two sub-rods 221 that are far apart from each other are respectively hinged to the front of the crossbar 212 of the two folding support rods 21. The folding central rod 22 can improve the structural stability between the two folding support rods 21, enhance the support effect on the sunshade cloth, and prevent the sunshade cloth from collapsing in the middle. At the same time, the folding central rod 22 can be rotated and folded when the two folding support rods 21 come closer to each other. The unfolding and folding do not require additional disassembly and assembly operations, making it convenient and quick to use.
[0030] In this embodiment, the bottom support 11 includes a front frame 111 and a rear frame 112 that are hinged together. Taking three side supports 12 as an example, the three side supports 12 are a front support 121, a rear support 122, and a left support 123 that are disposed above the bottom support 11. The left support 123 is a foldable structure, while the front support 121 and the rear support 123 are non-foldable frame supports. The right side of the bottom support 11 does not have side supports 12. Thus, the folding vehicle body 1 can be folded in front and behind by folding the bottom support 11 and the left support 123.
[0031] Furthermore, since the right side does not have a side bracket 12, the trailer can be used as a sunshade seat, with the bottom bracket 11 as the seat cushion and the left bracket 123 as the backrest. The sunshade bracket 2 on the top of the left bracket 123 is equipped with a sunshade cloth for sun protection. A locking mechanism 131 can be installed on the corresponding wheels 13 to lock the wheels 13, ensuring that the trailer can remain stationary and will not move around randomly. The structure of the locking mechanism 131 can refer to the prior art.
[0032] In this embodiment, a walking wheel 13 can be provided at the bottom left and right ends of the front bracket 121 and the rear bracket 122 respectively, and a handle 14 can be provided on the front side of the front bracket 121 to facilitate dragging the trailer for movement.
[0033] In this embodiment, the left support 123 may include a cross link assembly 125 consisting of two side uprights 120 and one or more "X"-shaped cross bars 124. The cross link assembly 125 in this embodiment has two cross bars.
[0034] The lower ends of both sides of the cross linkage assembly 125 are hinged to the bottom of the upright 120, and the upper ends of both sides are hinged to the middle of the upright 120 via short rods 126. The upper end of the upright 120 extends upward beyond the front support 121 and the rear support 122, and the folding support rod 21 is provided at the upper end of the upright 120. The short rods 126 ensure the folding function of the cross linkage assembly 125 while reducing product manufacturing costs.
[0035] Therefore, the left support 123 can be easily folded and retracted using the cross linkage assembly 125.
[0036] In this embodiment, a sunshade cloth can be laid on the sunshade bracket 2 of the multi-purpose trailer. At the same time, a basket (not shown) can be set between the bottom bracket 11 and each side bracket on the folding vehicle body 1 to facilitate carrying goods. The basket can also be made of cloth to facilitate the folding and closing of the folding vehicle body 1.
[0037] Example 2 like Figure 5As shown, the structure of this embodiment is basically the same as that of the above embodiment. The main difference is that in this embodiment, the upper ends of both sides of the cross link assembly 125 in the left bracket 123 are slidably connected to the middle of the upright 120 through the slide seat 127. The upper ends of both sides of the cross link assembly 125 are hinged to the slide seat 127. The slide seat 127 is slidably placed in the middle of the upright 120. This allows the cross link assembly 125 and the slide seat 127 to be folded and retracted more conveniently, making it more labor-saving to use.
[0038] Example 3 like Figure 6 and Figure 7 As shown, the structure of this embodiment is basically the same as that of the above embodiment 2. The main difference is that the top of the upright 120 in this embodiment is provided with a detachable movable insert 128, and the folding support rod 21 is installed on the top of the movable insert 128 to realize the detachable connection of the sunshade bracket 2, so that the sunshade bracket 2 can be disassembled when not needed.
[0039] Both the movable insert rod 128 and the upright rod 120 can be hollow rods. The bottom of the movable insert rod 128 can be provided with a spring buckle 129, and the top of the upright rod 120 is provided with an opening for the bottom of the movable insert rod 128 to be inserted. At the same time, the top side wall of the upright rod 120 is provided with a positioning through hole 1201 for the spring ball 1291 of the spring buckle 129 to be engaged. Thus, after the top of the movable insert rod 128 is inserted into the top opening of the upright rod 120, the spring ball 1291 of the spring buckle 129 is elastically engaged into the positioning through hole 1201 under the action of the spring piece 1292, so as to realize the insertion and fixed engagement of the top of the movable insert rod 128 and the upright rod 120.
[0040] Furthermore, a pressing sleeve 15 can be fitted onto the top of the upright 120 to facilitate the disassembly of the movable insert rod 128. The pressing sleeve 15 is fitted and secured to the outer periphery of the positioning through hole 1201 at the top of the upright 120. The pressing sleeve 15 is provided with a button 151 that can move radially through the positioning through hole 1201. Thus, by pressing the button 151 on the pressing sleeve 15, the spring pin of the spring buckle 129 can be controlled to exit the positioning through hole 1201. Subsequently, the folding support rod 21 and the movable insert rod 128 can be pulled out together from the top of the upright 120, making disassembly more convenient and effortless.
[0041] Example 4 like Figure 8 As shown, the structure of this embodiment is basically the same as that of the above embodiment. The main difference is that the right side of the bottom bracket 11 in this embodiment can also be provided with a side bracket 12 as a right bracket 130, and the right bracket 130 and the left bracket 123 are both foldable structures so as to completely frame the storage space of the trailer.
[0042] Furthermore, the front support 121 and the rear support 122 can also be configured as foldable structures, and can also be further folded in the left and right directions. The corresponding front frame 111 and rear frame 112 of the bottom support 11 are also foldable structures that can be folded in the front, back, left and right directions.
[0043] Therefore, the folding vehicle body 1 of this embodiment can be folded in all directions, greatly reducing its volume.
[0044] In this embodiment, the folding support rod 21 can be set on the top of the auxiliary rod 23 installed on the outside of the upright 120, or it can be located above the upright 120, which can facilitate the modification of existing trailers.
