Detailed Implementation

[0049] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] like Figures 1-24 As shown, the vehicle of this utility model has an unfolded state and a folded state. The vehicle includes a vehicle body, a canopy assembly 7 disposed on the vehicle body, and a wheel assembly disposed at the bottom of the vehicle body.

[0051] The carrier body has an unfolded state and a folded state, as Figures 1-24 As shown, the carrier body comprises a pair of support frames arranged in the front-rear direction and a carrying frame arranged between the pair of support frames, the carrying frame comprising a bottom frame, a front side frame 112 arranged on the bottom frame, a rear side frame 122, and a side wall assembly connected between the front side frame 112 and the rear side frame 122. The side wall assembly is arranged on the left and right sides, and the front side frame 112, the rear side frame 122, the side wall assembly on the left and right sides, and the bottom frame enclose a carrying space arranged with an upward opening.

[0052] In this embodiment, the pair of support frames are both in a closed frame structure and are arranged vertically, and the support frame located at the front is defined as a front wall frame 111, and the support frame located at the rear is defined as a rear wall frame 121.

[0053] The front side frame 112 is fixedly arranged on the left and right sides of the front wall frame 111 and is located on the inner side of the front wall frame 111, where the inner side refers to the closed frame structure of the front wall frame 111 in the front projection direction, as shown in Figure 10 Figures 12-14 .

[0054] The rear side frame 122 is fixedly arranged on the left and right sides of the rear wall frame 121 and is located on the inner side of the rear wall frame 121, where the inner side refers to the closed frame structure of the rear wall frame 121 in the front projection direction, as shown in Figure 10 Figures 12-14 .

[0055] In this application, the front side frame 112 and the front wall frame 111, and the rear side frame 122 and the rear wall frame 112 are arranged in an inner-outer stacked structure, so that the structural strength and stability of the formed carrier body are both good.

[0056] Specifically, the front wall frame 111 comprises a pair of vertical side frames arranged opposite in the left-right direction, and the front side frame 112 comprises a front vertical support rod extending in the up-down direction, the front vertical support rod is fixedly connected with the vertical side frame and a gap is left between the two. In this embodiment, the front vertical support rod and the lower part of the vertical side frame are fixedly connected through a fixed connecting piece 113. A reinforcing connecting piece 114 is also arranged between the upper part of the front vertical support rod and the vertical side frame to fixedly connect the two, thereby improving the reliability of the connection between the front vertical support rod and the vertical side frame, and improving the structural strength of the carrier, as shown in Figure 25 .

[0057] ​​Similarly, the rear frame 121 includes a pair of vertical frames arranged opposite to each other in the left-right direction, and the rear side frame 122 includes a rear vertical support rod extending in the up-down direction, which is fixedly connected with the vertical frames and has a gap therebetween. In this embodiment, the rear vertical support rod and the lower part of the vertical frame are fixedly connected by the fixing connector 113. The upper part of the rear vertical support rod and the vertical frame are also provided with a reinforcing connector 114 to fixedly connect them, thereby improving the reliability of the connection between the rear vertical support rod 122 and the vertical frame, and improving the structural strength of the carrier, as shown in Figure 26

[0058] The chassis includes a bottom support arm supported between a pair of support frames, which includes a first bottom support rod 21 and a second bottom support rod 22 rotatably connected at one end, the other end of the first bottom support rod 21 is rotatably connected with the lower part of the front side frame 112, and the other end of the second bottom support rod 22 is rotatably connected with the lower part of the rear side frame 122.

[0059] The rotation center lines of the first bottom support rod 21 and the front side frame 112, the second bottom support rod 22 and the rear side frame 122, and the second bottom support rod 22 and the first bottom support rod 21 are all in the left-right direction. In this way, when the carrier is folded, the first bottom support rod 21 and the second bottom support rod 22 are both turned upward to make the front frame 111 and the rear frame 121 close to each other.

[0060] The at least one side frame assembly has a door frame structure, which includes a first door frame 31 rotatably connected to the front side frame 112 and a second door frame 32 rotatably connected to the rear side frame 122.

[0061] The rotation center lines of the first door frame 31 and the front side frame 112, and the second door frame 32 and the rear side frame 122 are all in the up-down direction. When the carrier is folded, the first door frame 31 is rotated relative to the front side frame 112 to the inside of the carrier body, and the second door frame 32 is rotated relative to the rear side frame 122 to the inside of the carrier body.

[0062] ​The rotating connection position of the first bottom support rod 21 with the front vertical support rod is further away from the vertical frame than the mounting position of the front vertical support rod on the vertical frame, and the carrier can leave a placement space for the first door frame 31 between the first bottom support rod 21 and the front vertical support rod after folding. Similarly, the rotating connection position of the second bottom support rod 22 with the rear vertical support rod is further away from the vertical frame than the mounting position of the rear vertical support rod on the vertical frame, so that the carrier can leave a placement space for the second door frame 32 between the second bottom support rod 22 and the rear vertical support rod after folding. Thus, when the carrier is folded, the first door frame 31 is located between the first bottom support rod 21 and the front side frame 112, and the second door frame 32 is located between the second bottom support rod 22 and the rear side frame 122, so that the carrier is compact in structure and small in size when folded.

[0063] The carrier frame also has a rotating connection structure, and the first door frame 31 is rotatably connected with the front side frame 112 through the rotating connection structure. The rotating connection structure includes a sleeve 33 arranged on the first door frame 31, which is sleeved on the front vertical support rod and can rotate around the front vertical support rod. The rotating connection structure also has a limiting structure for limiting the movement of the sleeve 33 in the axial direction of the front vertical support rod, and the limiting structure includes positioning grooves 112a arranged on the front vertical support rod respectively, which are arranged around the front vertical support rod, and the sleeve 33 on the first door frame 31 is rotatably installed in the positioning grooves 112a.

[0064] Similarly, the second door frame 32 is rotatably connected with the rear side frame 122 through the rotating connection structure, and the sleeve 33 is sleeved on the rear vertical support rod and can rotate around the rear vertical support rod. The rear vertical support rod is provided with a positioning groove 122a arranged around the rear vertical support rod, and the sleeve 33 on the second door frame 32 is rotatably installed in the positioning groove 122a.

[0065] The door frame structure has a closed state and an open state. When the door frame structure is in the open state, the first door frame 31 and the second door frame 32 are rotated to positions away from each other and extend in the left-right direction, so as to form an opening on the side of the carrier frame for entering and exiting the carrying space, thereby facilitating the children to enter and exit the carrier, as shown in Figure 4 and Figure 5 When the door frame structure is in the closed state, the first door frame 31 and the second door frame 32 are rotated to a closed position to close the opening, and at this time, the first door frame 31 and the second door frame 32 extend in the front-rear direction, as shown in Figures 1-3 , Figures 6-9

[0066] ​The first door frame 31 is located above the first bottom support rod 21, and the front side frame 112 is arranged behind the front surrounding frame 111. The second door frame 32 is located above the second bottom support rod 22, and the rear side frame 122 is arranged in front of the rear surrounding frame 121. The first door frame 31 is capable of rotating relative to the front side frame 112 to the outside of the vehicle body, and the second door frame 32 is capable of rotating relative to the rear side frame 122 to the outside of the vehicle body, so that the door frame structure is switched from the closed state to the open state. When the door frame structure is in the open state, the first door frame 31 abuts against the front surrounding frame 111, thereby limiting the first door frame 31. The second door frame 32 abuts against the rear surrounding frame 121, thereby limiting the second door frame 32.

[0067] The first door frame 31 movably has a locking member 34, which is capable of moving between a locked position and an unlocked position. When the door frame structure is in the closed state, the locking member is in the locked position, and the locking member 34 extends to the bottom of the first door frame 31. The first bottom support rod 21 is provided with a locking groove matched with the locking member 34, and the locking member 34 is positioned in the locking groove, thereby locking the position of the first door frame 31. When the locking member 34 is out of the locking groove, the first door frame 31 is unlocked and can rotate relative to the front side frame 112, so that the door frame structure is opened.

[0068] Similarly, the second door frame 31 also movably has a locking member 34, which is capable of moving between a locked position and an unlocked position. When the door frame structure is in the closed state, the locking member is in the locked position, and the locking member 34 extends to the bottom of the second door frame 32. The second bottom support rod 22 is provided with a locking groove matched with the locking member 34, and the locking member 34 is positioned in the locking groove, thereby locking the position of the second door frame 32. When the locking member 34 is out of the locking groove, the second door frame 32 is unlocked and can rotate relative to the rear side frame 122, so that the door frame structure is opened.

[0069] In this embodiment, the first door frame 31 and the second door frame 32 are each rotated about 90 degrees from the closed state to the open state.

[0070] As shown in Figures 1-9 The side surrounding assembly can further include side guardrails, which are respectively located on the left and right sides of the door frame structure. The side guardrail includes a front side rod 41 and a rear side rod 42. In this embodiment, the front part of the front side rod 41 is rotationally connected to the upper part of the front side frame 112, and the rear part of the rear side rod 42 is rotationally connected to the upper part of the rear side frame 122. A connecting member 43 is arranged between the front side rod 41 and the rear side rod 42, and the rear part of the front side rod 41 and the front part of the rear side rod 42 are respectively rotationally connected to the connecting member 43.

[0071] The rotation center lines of the front side rod 41 and the front side frame 112, the rear side rod 42 and the rear side frame 122, the front side rod 41 and the connecting piece 43, and the rear side rod 42 and the connecting piece 43 all extend along the up-down direction. When the carrier is in the unfolded state, the front side rod 41 and the rear side rod 42 both extend along the front-rear direction. When the carrier is folded, the front side rod 41 and the rear side rod 42 relatively rotate in the horizontal plane to the inside of the carrier. When the carrier is in the folded state, the front side rod 41 and the rear side rod 42 both extend along the left-right direction.

[0072] The height of the uppermost end of the door frame structure is not higher than the height of the side guardrail, so that when the carrier is folded, the front side rod 41 is above the first door frame 31, and the rear side rod 42 is above the second door frame 32, so that the structural size of the carrier in the front-rear direction is small after being folded.

[0073] As shown in Figures 1-9 , the carrier body can further include a push handle 5 which is rotatably arranged on the support frame. In this embodiment, the push handle 5 is rotatably arranged on the upper part of the rear surrounding frame 121. The push handle 5 has a first use position, a second use position and a folded position.

[0074] When the push handle 5 is in the first use position, the carrier is in the folded state, the push handle 5 is rotated upward to be close to the rear surrounding frame 121, and the push handle 5 extends out of the top of the support frame to serve as a handle for pulling the carrier after being folded, and a first included angle A is formed between the push handle 5 and the rear surrounding frame 121, as shown in Figure 23 and Figure 24 At this time, the operator can stand behind the carrier and hold the push handle 5 to pull the carrier backward.

[0075] When the push handle 5 is in the folded position, the push handle 5 is rotated downward to be close to the rear surrounding frame 121, as shown in Figure 8 , Figure 9 , Figure 21 and Figure 22 .

[0076] When the push handle 5 is in the second use position, the carrier is in the unfolded state, the push handle 5 is away from the rear surrounding frame 121, a second included angle B is formed between the push handle 5 and the rear surrounding frame 121, and the first included angle A is greater than the second included angle B, as shown in Figure 6 and Figure 7 At this time, the operator can stand behind the carrier and hold the push handle 5 to push the carrier forward.

[0077] The carrier body can further include a mop 6 which is rotatably connected with the bottom of the front surrounding frame 111. The mop 6 has a use state and a folded state. When the mop 6 is in the use state, the carrier is in the unfolded state, and the mop 6 is rotated forward to a position away from the front surrounding frame 111, as shown in Figure 8 and Figure 9As shown, at this time, the operator can stand in front of the carrier and hold the mop 6 to drag the carrier forward. When the mop 6 is in the folded state, the mop 6 is turned rearward to be close to the front frame 111, as shown in Figure 6 , Figure 7 , Figure 21 and Figure 22 .

[0078] When the carrier is in the unfolded state, the operator can choose to use one of the two push handles 5 and the mop 6, and when the carrier is in the folded state, only the push handle 5 can be used.

[0079] As shown in Figures 1-9 , the canopy assembly 7 is arranged on the carrier body and forms a shelter above the carrying space of the carrier body. The canopy assembly 7 includes a main canopy frame, a sub-canopy frame, and a canopy cloth.

[0080] The sub-canopy frame is arranged on the main canopy frame, and the canopy cloth includes a main canopy cloth 72 and a sub-canopy cloth 74. The main canopy cloth 72 is arranged on the main canopy frame, and the sub-canopy cloth 74 is arranged on the sub-canopy frame. The main canopy cloth 72 and the sub-canopy cloth 74 can be integrally arranged, or they can be separately arranged and connected by a connecting member such as a zipper.

[0081] The sub-canopy frame has a supporting state and a non-supporting state. When the sub-canopy frame is in the supporting state, the sub-canopy frame is located on the top of the main canopy frame and is arranged outward from the main canopy frame. In the horizontal direction, a plurality of sub-canopy frames are arranged around the outer contour of the main canopy frame. The main canopy cloth 72 covers the top of the main canopy frame, and the sub-canopy cloth 74 covers the top of the sub-canopy frame. At the same time, the sub-canopy cloth 74 extends outside the main canopy cloth 72, thereby increasing the sheltering range of the canopy assembly 7, as shown in Figure 1 , Figure 2 , Figures 4-9 . At this time, the sub-canopy cloth 74 and the main canopy cloth 72 jointly provide sunshade or rain protection, so that the canopy assembly 7 forms a relatively large canopy assembly 7. At this time, the carrier is mainly used in a relatively strong sunlight environment.

[0082] When the sub-canopy frame is in the non-supporting state, the sub-canopy frame is folded to the main canopy frame, as shown in Figure 3 , or the sub-canopy frame can be detached from the main canopy frame. At this time, only the main canopy cloth 72 provides sunshade or rain protection, so that the canopy assembly 7 forms a relatively small canopy assembly 7.

[0083] Specifically, the main canopy frame includes a plurality of vertical support rods 71 arranged in the vertical direction, and the sub-canopy frame includes a sub-canopy rod 73 arranged on each vertical support rod 71. When the sub-canopy frame is in the supporting state, each sub-canopy rod 73 is located on the top of the vertical support rod 71.

[0084] In this embodiment, four vertical support rods 71 are provided, and the four vertical support rods 71 are respectively and correspondingly arranged on the front side frame 112 and the rear side frame 122. The four vertical support rods 71 are arranged in a rectangular shape in the horizontal plane, and correspondingly, the four auxiliary canopy rods 73 are also provided. When the auxiliary canopy frame is in the supporting state, the four auxiliary canopy rods 73 are respectively arranged at the four corners of the rectangle, and each auxiliary canopy rod 73 extends along the diagonal direction of the rectangle. At this time, the auxiliary canopy cloth 74 is arranged on the opposite sides of the auxiliary canopy rod 73, that is, the auxiliary canopy cloth 74 is arranged on the entire outer circumferential portion of the main canopy 72, so that the shielding area of the canopy assembly 7 is increased on all four sides of the main canopy cloth 72, so that the shielding area of the canopy assembly 7 is larger, as shown in Figures 1-9

[0085] Of course, when the auxiliary canopy frame is in the supporting state, each auxiliary canopy rod 73 can also extend along the side length direction of the rectangle, and at this time, the auxiliary canopy cloth 74 is arranged on one side of the auxiliary canopy rod 73, that is, the auxiliary canopy cloth 74 is arranged on part of the outer circumferential portion of the main canopy cloth 73. Specifically, when the auxiliary canopy rod 73 extends in the left-right direction, the auxiliary canopy cloth 74 is arranged on the left and right sides of the outer circumferential portion of the main canopy cloth 71. When the auxiliary canopy rod 73 extends in the front-rear direction, the auxiliary canopy cloth 74 is arranged on the front and rear sides of the outer circumferential portion of the main canopy cloth 71, that is, the shielding area of the canopy assembly 7 is increased on the opposite sides of the main canopy cloth 72.

[0086] The main canopy frame can also include a horizontal support rod 75, and the horizontal support rod 75 is fixedly arranged on the top of the vertical support rod 71. At this time, the main canopy cloth 72 can be arranged on the horizontal support rod 75, and the auxiliary canopy rod 73 can also be arranged on the horizontal support rod 75.

[0087] In this embodiment, the two ends of the horizontal support rod 75 are respectively connected or integrally arranged with the top of the two adjacent vertical support rods 71, thereby forming a canopy rod assembly. The main canopy frame includes a pair of oppositely arranged canopy rod assemblies, and the main canopy cloth 72 is supported between the pair of canopy rod assemblies.

[0088] Of course, the vertical support rod 71 can also be fixedly connected to the middle portion of the horizontal support rod 75.

[0089] The arrangement of the horizontal support rod 75 can better support the main canopy cloth 72 and prevent the main canopy cloth 72 from collapsing. The horizontal support rod 75 has an upwardly convex arc-shaped structure, so that after the horizontal support rod 75 supports the main canopy cloth 72, the main canopy cloth 72 also has an upwardly convex arc-shaped structure, so that rainwater can flow along the main canopy cloth 72 to the outside of the vehicle and will not deposit on the top of the main canopy cloth 72.

[0090] In this embodiment, each auxiliary canopy rod 73 is rotatably connected to each vertical support rod 71 through a rotating shaft 76.

[0091] ​When the sub-canopy frame is in the supporting state, each sub-canopy rod 73 is rotated to be away from the vertical support rod 71, the sub-canopy rod 73 has a joint end connected with the vertical support rod 71 and a free end arranged opposite to the joint end, at this time, the height of the position where the joint end is located is higher than the height of the position where the free end is located, so that the sub-canopy rod 73 is arranged to extend in a slanting downward direction as a whole. In this way, the sub-canopy cloth 74 is arranged to form a structure inclined from the inside to the outside of the canopy assembly 7 and from the top to the bottom, so that rainwater can flow along the sub-canopy cloth 74 to the outside of the vehicle and cannot be deposited on the top of the sub-canopy cloth 74 or flow back to the top of the main-canopy cloth 72.

[0092] When the sub-canopy frame is in the non-supporting state, the sub-canopy rod 73 is rotated to be close to the vertical support rod 71 and is arranged to extend in a direction approximately parallel to the vertical support rod 71. At this time, the sub-canopy cloth 74 extends from the joint with the main-canopy cloth 72 to the lower part of the main-canopy cloth 72, thereby forming an enclosure, as shown in Figure 3 The enclosure formed by the sub-canopy cloth 74 can prevent wind and rain, and at this time, the vehicle is mainly suitable for use in a place where the wind and rain are relatively large.

[0093] In other embodiments, the sub-canopy frame can also be arranged to slide on the main-canopy frame, for example, the sub-canopy rod 73 is arranged to slide on the horizontal support rod 75. When the sub-canopy frame is in the supporting state, the sub-canopy rod 73 slides outward to extend outside the main-canopy frame, and when the sub-canopy rod 73 slides outward, the sub-canopy cloth 74 is unfolded. When the sub-canopy frame is in the non-supporting state, the sub-canopy rod 73 slides inward to retract into the main-canopy frame, and when the sub-canopy rod 73 slides inward, the sub-canopy cloth 74 is folded.

[0094] Preferably, the canopy assembly 7 is arranged to slide up and down on the vehicle body. In this embodiment, the front side frame 112 and the rear side frame 122 are both provided with a tubular cavity extending along the length direction thereof, and the lower part of each main-canopy rod 71 extends into the tubular cavity of the front side frame 112 and the rear side frame 122 and is arranged to slide up and down along the tubular cavity.

[0095] The vehicle further comprises a locking mechanism arranged between each main-canopy rod 71 and the front side frame 112 / rear side frame 122, respectively, and the relative positions of the main-canopy rod 71 and the front side frame 112 and the main-canopy rod 71 and the rear side frame 122 are locked by the locking mechanism.

[0096] The locking mechanism comprises a locking pin 81 arranged to slide on the main-canopy rod 71 and a locking hole arranged on the front side frame 112 / rear side frame 122, respectively. When the locking mechanism is in the locked state, the locking pin 81 is inserted into the locking hole, and when the locking mechanism is in the unlocked state, the locking pin 81 is withdrawn from the locking hole.

[0097] The carrier further comprises an unlocking mechanism, the locking mechanism drives the unlocking mechanism when the locking mechanism operates the unlocking mechanism in the locked state. The unlocking mechanism comprises an unlocking knob 82 and a traction cable 83. The unlocking knob 82 is movably arranged on the transverse support rod 75. One end of the traction cable 83 is arranged on the unlocking knob 82, and the other end of the traction cable 83 is arranged on the locking pin 81.

[0098] The wheel assembly comprises front wheels 91 and rear wheels 92. The front wheels 91 are arranged on the left and right sides of the bottom of the front surrounding frame 111 respectively, and the front wheels 91 are universal wheels. The rear wheels 92 are arranged on the left and right sides of the bottom of the rear surrounding frame 121 respectively, and the rear wheels 92 are directional wheels.

[0099] When the carrier is in the unfolded state, the door frame structure can be in the closed state, as shown in Figures 1-3 ; the first door frame 31 and the second door frame 32 can also be respectively rotated to the outside of the carrier to make the door frame structure in the open state, as shown in Figure 4 and Figure 5 . The main canopy rod 71 can slide up and down relative to the front side frame 112 and the rear side frame 122, so that the canopy assembly is in a high gear position or in a low gear position, as shown in Figure 10 , Figures 12-14 . The auxiliary canopy frame can be in a supporting state or a non-supporting state, as shown in Figures 1-3 .

[0100] When the carrier needs to be folded, the canopy assembly 7 is in the non-supporting state, the unlocking mechanism is operated to make the locking mechanism unlocked, and then the canopy assembly 7 is slid downward as a whole to the lowest position, the push handle 5 is rotated downward to the folded position, and the mop 6 is rotated rearward to the folded state, as shown in Figure 15 and Figure 16 . The first door frame 31 is rotated to the inside of the carrier to close to the front surrounding frame 111, and the second door frame 32 is rotated to the inside of the carrier to close to the rear surrounding frame 121, as shown in Figure 17 and Figure 18 . The first bottom support rod 21 is relatively rotated to close to the second bottom support rod 22, so that the front surrounding frame 111 and the rear surrounding frame 121 move towards each other, and the front side rod 41 and the rear side rod 42 are relatively rotated to close to each other in the horizontal plane, and the folding process is as shown in Figure 19 and Figure 20 .

[0101] When the carrier is in the folded state, as shown in Figure 21 and Figure 22As shown, the first bottom support rod 21, the second bottom support rod 22, the first door frame 31, the second door frame 32, the front side rod 41 and the rear side rod 42 are all accommodated between the front surrounding frame 111 and the rear surrounding frame 121, the front side rod 41 is accommodated above the first door frame 31, and the rear side rod 42 is accommodated above the second door frame 32, which makes the folded carrier compact and flat in the front-rear direction, and makes the overall structure of the carrier smaller. The front wheel assembly 91 is accommodated between the two groups of rear wheel assemblies 92, and the front wheel assembly 91 and the rear wheel assembly 92 are commonly supported on the ground. At this time, the push handle 5 can be turned upward to be close to the rear surrounding frame 121, so that the push handle 5 is in the first use position, as shown in Figure 23 and Figure 24 As shown, the carrier can be dragged backward by holding the push handle 5, which is convenient for carrying the carrier.
