[0001] The utility model relates to the technical field of wheelbarrows, in particular to a wheelbarrow. Background Art

[0002] The shock absorber, also known as the shock absorber, is a crucial accessory on a unicycle, playing a crucial role in ensuring the safety and comfort of the unicycle. During the unicycle's operation, the shock absorber constantly adjusts the height of the active frame and reduces vibration. Over extended periods of operation, the internal structure of the shock absorber is prone to malfunction, or even failure, affecting its proper function and the unicycle's proper use.

[0003] In the prior art, in a unicycle with rear-end shock absorption, the shock absorber is arranged at the rear of the frame through a connecting rod structure, and all or most of the body of the shock absorber is blocked by various brackets and the frame. When repairing or maintaining the shock absorber, it is generally necessary to disassemble the frame to expose the connecting rod structure and the shock absorber, which is cumbersome. In addition, due to the structural characteristics of the unicycle, a large number of components such as electronic control boxes or battery boxes are generally fixed on the frame, which has a complex structure and many lines. Frequent disassembly can easily cause malfunction of the electronic control box or battery box, affecting the normal operation of the unicycle. Utility Model Content

Therefore, they cannot be understood as limiting the present invention.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0048] See Figure 1 and Figure 2 The utility model discloses a wheelbarrow, comprising a wheel 1, a frame 2, and a shock-absorbing component; the shock-absorbing component reduces vibration of the frame to improve comfort.

[0049] In this unicycle, the frame 2 includes a fixed frame 21 and a movable frame 22. Figure 1 As shown, the movable frame 22 is movably mounted on the fixed frame 21, and when the wheelbarrow is upright, the movable frame 22 is located above the fixed frame 21. At the same time, in this solution, a connecting seat 8 is detachably connected to the movable frame.

[0050] The shock absorber assembly includes a first connecting bracket 6, a second connecting bracket 7, and a shock absorber 5. The first connecting bracket 6 and the second connecting bracket 7 are rotatably connected. The first connecting bracket is rotatably connected to the fixed frame, and the second connecting bracket is rotatably connected to the connecting base 9. One end of the shock absorber is connected to the first connecting bracket, and the other end of the shock absorber is rotatably connected to the second connecting bracket or the connecting base.

[0051] After the connecting seat is separated from the movable frame, the connecting seat can be turned over and exposed with the shock absorber.

[0052] Based on the above solution, when the shock absorber needs to be inspected and repaired, the connecting seat is first removed from the movable frame, so that the connection end of the shock absorber assembly and the movable frame is unlocked. At this time, the shock absorber assembly can be turned over as a whole toward the rear end of the unicycle or partially pulled out toward the top of the movable frame, so that part or all of the shock absorber can be exposed outside the movable frame, so that the maintenance personnel's actions of repairing and maintaining the shock absorber will not be blocked by the movable frame, which facilitates the repair and maintenance of the shock absorber, reduces the difficulty of the shock absorber repair and maintenance operations, and avoids the shock absorber repair and maintenance being hindered by the movable frame.

[0053] Depend on Figure 7 As shown, the shock absorber 5 includes a first end 51 and a second end 52. The first end 51 is connected to the fixed frame 21, and the second end 52 is directly or indirectly detachably and rotatably connected to the movable frame 22, thereby achieving shock absorption for the movable frame and further shock absorption for the seat mounted on the movable frame. Here, the second end 52 of the shock absorber is rotatably connected to the connecting seat, achieving an indirect detachable and rotatable connection with the movable frame.

[0054] After the connecting seat 8 is separated from the movable frame, that is, after the second end 52 of the shock absorber is separated from the movable frame 22, the shock absorber 5 can be flipped toward the rear end of the wheelbarrow or pulled out above the movable frame, and part of the structure of the shock absorber is exposed above the movable frame. The shock absorber 5 is at least partially exposed from the movable frame 22, which is convenient for maintenance.

[0055] In this technical solution, if Figure 2 As shown, the fixed frame 21 is connected to the axle of the wheel 1, and when the unicycle is upright, the fixed frame 21 is fixed above the wheel 1. The movable frame 22 is slidably connected to the fixed frame 21, which facilitates the installation of the movable frame. At the same time, the movable frame is connected to the shock absorber, so that the shock absorber can reduce the vibration of the movable frame. When the unicycle is bumpy, the movable frame will slide up or down relative to the fixed frame to achieve shock absorption and buffering effects.

[0056] In order to realize the sliding connection between the movable frame and the fixed frame, Figure 2 As shown, a guide member 4, arranged radially along the wheel 1, is fixedly connected to the fixed frame 21. One end of the guide member 4 is fixedly connected to the axle of the wheel 1 and is also connected to the pedal of the unicycle. The movable frame 22 is slidably connected to the other end of the guide member 4. The movable frame is slidably connected to the guide member 4. When the unicycle is bumpy, the movable frame slides up and down along the guide member 4 to achieve the purpose of shock absorption and cushioning.

[0057] In the above scheme, the guide parts are generally preferably made of guide rods, guide columns, steel pipes and other structures, and are made of metal materials to ensure their strength and realize the installation of the movable frame and the fixed frame. At the same time, the structure is simple, easy to install and connect, and low cost.

[0058] Based on the above scheme, when the wheelbarrow is in an upright position, the fixed frame is located above the wheels, and the fixed frame is located above the movable frame. When the shock absorber is installed, in order to ensure that the movable frame is installed stably and balanced above the fixed frame and reduce the overall weight of the wheelbarrow, it is also necessary to ensure that the fixed frame and the movable frame are within the wheel range of the wheelbarrow, so that the wheelbarrow can control its forward or backward distance during travel and avoid collisions. Therefore, the installation of the shock absorber is not vertically installed like the guide member 4. The shock absorber is combined with the fixed frame and the movable frame to form a triangular structure, thereby improving the stability of the shock absorber, the fixed frame and the movable frame after installation. Because the guide member 4 is in a vertical state, the shock absorber is installed in an inclined state. Installing the shock absorber in an inclined state not only utilizes the shock absorber's own structure to provide certain support to the movable frame, ensuring the stability of the movable frame, but also improves the buffering capacity of the shock absorber by installing the shock absorber in an inclined state.

[0059] Based on the above installation requirements and purposes of the shock absorber, the shock absorber is in an inclined state. To achieve the installation of the shock absorber in an inclined state, such as Figure 2As shown, in addition to the shock absorber 5, the shock absorption assembly also includes a first connecting bracket 6 and a second connecting bracket 7. The first connecting bracket and the second connecting bracket are rotatably connected. The first connecting bracket is rotatably connected to the fixed frame, and the second connecting bracket is rotatably connected to the connecting seat 8. One end of the shock absorber 5 is connected to the first connecting bracket, and the other end of the shock absorber 5 is rotatably connected to the second connecting bracket or the connecting seat 8. Multiple triangular structures can be formed between the fixed frame 21, the movable frame, the shock absorber, the first connecting bracket 6, and the second connecting bracket. This not only facilitates the installation of the shock absorber, but also enables the shock absorber to achieve the purpose of shock absorption and buffering on the movable frame.

[0060] After the second end 52 is separated from the movable frame 22, the shock absorber 5 can be flipped toward the rear end of the wheelbarrow around the first connecting bracket 6 and the fixed bracket, or moved up and down to be partially pulled out of the movable frame. The shock absorber 5 is at least partially flipped out of the movable frame 22, and the shock absorber 5 is at least partially exposed.

[0061] like Figure 2 As shown, when the shock absorber needs to be inspected or repaired, the connecting seat is removed from the movable frame to separate the shock absorber assembly from the movable frame. While the movable frame is kept slidingly connected to the guide member 4, the shock absorber assembly is flipped backward or pulled upward to expose at least part of the shock absorber, thereby facilitating the maintenance of the shock absorber.

[0062] In one embodiment, in order to facilitate the installation of the first connecting bracket on the fixed frame and the installation of the shock absorber on the first connecting bracket and the movable frame, the first end of the shock absorber should generally be located behind the second end. Therefore, when the shock absorber is flipped over, the first connecting bracket and the shock absorber are flipped toward the rear end of the wheelbarrow, which is relatively simple and convenient to operate and can ensure that the shock absorber is less interfered with by the movable frame after being flipped out.

[0063] In the above solution, after the second end 52 is separated from the movable frame 22, the shock absorber 5 can be turned around the first connecting bracket 6 and the fixed bracket to the rear end of the wheelbarrow, and the shock absorber 5 is at least partially turned out of the movable frame 22, and the shock absorber 5 is at least partially exposed. Figure 2 As shown, when the shock absorber is flipped, it is limited by the position of the first connecting bracket and the wheel. Therefore, when the shock absorber rotates around the first connecting bracket 6 and the fixed bracket to flip toward the rear end of the wheelbarrow, generally part or most of the structure of the shock absorber is exposed, and it is difficult to ensure that the entire structure of the shock absorber is exposed outside the movable frame. Of course, after part of the structure of the shock absorber is exposed, maintenance personnel can inspect and repair the shock absorber from the rear of the wheel, and the shielding range of the movable frame or the first connecting bracket to the shock absorber is reduced, which is convenient for the inspection and maintenance of the shock absorber. Figure 7 and Figure 11 As shown, Figure 7 The shock absorber is in normal installation state. Figure 11 This is the position state of the shock absorber during maintenance. It can be clearly seen that after the shock absorber rotates backward, the obstruction and hindrance of the movable frame to the shock absorber are reduced. At the same time, the first connecting bracket fixedly connected to the shock absorber has its angle changed, and the obstruction of the shock absorber by the first connecting bracket is also reduced, which further facilitates the inspection and maintenance of the shock absorber.

[0064] like Figure 2 、 Figure 7 、 Figure 8 and Figure 11 As shown in , along the front-to-back direction of the seat 3, the seat 3 includes a front seat 32 and a rear seat 31 detachably fixed to the movable frame 22, and the front seat 32 and the rear seat 31 are respectively arranged close to the front and rear of the wheelbarrow.

[0065] When the unicycle is in an upright position, the shock absorber 5 is located below the rear seat 31 , and the position where the second end 52 is detachably and rotatably connected to the movable frame 22 is located below the rear seat 31 .

[0066] The movable frame is provided with an escape notch for providing a movable space for the shock absorber assembly, and the escape notch is located below the rear seat portion; after the connecting seat is separated from the movable frame, the shock absorber can be flipped toward the rear end of the wheelbarrow through the escape notch, or the shock absorber can be at least partially pulled out toward the top of the movable frame through the escape notch.

[0067] The movable frame 22 is provided with an escape notch 23 , and the escape notch 23 is located below the rear seat portion 31 .

[0068] After the second end 52 is separated from the movable frame 22 , the shock absorber 5 can be flipped toward the rear end of the unicycle through the avoidance gap 23 , and the shock absorber 5 is at least partially flipped out of the avoidance gap 23 , and is at least partially exposed outside the movable frame 22 .

[0069] Based on the above solution, the shock absorber is tilted and its second end is detachably and rotatably connected to the movable frame. The second end is located forward of the first end. To achieve support and shock absorption for the movable frame, the second end is connected to the movable frame near the middle of the movable frame, near the guide member 4. As a result, the rear half of the movable frame significantly obstructs the shock absorber, and the rear seat mounted on the movable frame and the movable frame supporting the rear seat significantly obstruct the shock absorber. To ensure smooth backward flipping of the shock absorber, a clearance gap 23 is provided on the movable frame. The clearance gap 23 facilitates backward flipping of the shock absorber and prevents interference between the shock absorber and the movable frame during backward flipping. On the other hand, due to the position of the first connecting bracket and the wheel, when the first connecting bracket and the shock absorber flip backward, the shock absorber reaches its limit of flipping when the first connecting bracket contacts the wheel. At this time, a portion of the structure on the shock absorber can be moved to expose the clearance gap, further exposing the shock absorber and facilitating maintenance operations on the shock absorber.

[0070] like Figure 2 and Figure 11 As shown, in order to extend the length of the seat and improve the sitting comfort, an extension frame 33 is further connected to the rear end of the movable frame. The rear seat 31 partially falls on the rear extension frame 33. At this time, when the first connecting bracket and the shock absorber are flipped backward, the extension frame 33 can remain connected to the rear end of the movable frame. After the flip, the shock absorber is located below the extension frame 33. The extension frame 33 does not hinder the maintenance operation of the shock absorber, or does not cause significant obstruction.

[0071] Based on the above solution, the detachable and rotatable connection position of the shock absorber and the movable frame is located below the rear seat portion. When the shock absorber needs to be flipped over, the rear seat portion needs to be removed from the movable frame, but the front seat portion installed on the movable frame can remain in the state of being installed on the movable frame. The movable frame below the front seat portion is generally fixed with a battery box or an electronic control box. When repairing the shock absorber, the movable frame does not need to be disassembled, that is, the battery box and the electronic control box on the movable frame will not be interfered with or damaged, which simplifies the operation during shock absorber repair, reduces the failure rate of the unicycle caused by human action, extends the service life of the unicycle, and reduces the cost of using the unicycle.

[0072] Based on the above solution, a pull rod 9 is detachably connected to the movable frame. The pull rod is used to pull the unicycle when not being ridden. One end of the pull rod 9 is rotatably connected to the connecting seat, and the other end extends backward and overlaps the extension frame 33, thereby pulling the unicycle and supporting the rear seat. When the shock absorber needs to be flipped backward, the connecting seat can be pulled by the pull rod, and the connecting seat then drives the shock absorber and the first connecting bracket to flip, without affecting the normal flipping of the shock absorber.

[0073] In the above solution, the pull rod is rotatably connected to the connecting seat, and the pull rod can be rotated to open or close relative to the movable frame to pull the wheelbarrow.

[0074] The pull rod is provided with a rear seat portion, which, when the pull rod rotates and retracts relative to the movable frame, is shielded from view above the connecting seat. The rear seat portion not only shields the pull rod but also allows for sitting or standing. In one embodiment, the rear seat portion is fixedly connected to the pull rod. When the unicycle is pulled, the rear seat portion is fixed to the pull rod, which does not affect the pulling of the unicycle and avoids the need for additional components to be held or stored.

[0075] In one embodiment, the pull rod is detachably connected to the connecting base. After the rear seat is separated from the connecting base by the pull rod, the connecting base is exposed, allowing it to be removed from the movable frame. This facilitates disassembly of the connecting base and avoids the need to disassemble the rear seat before disassembling the connecting base. In this case, due to the presence of the rear seat and the pull rod, the shock absorber assembly may be restricted and unable to flip backward. In this case, the connecting base can be pulled to extend the shock absorber assembly above the movable frame, exposing the shock absorber portion above the movable frame, facilitating maintenance of the shock absorber.

[0076] Of course, in the above solution, due to the presence of the extension frame and the pull rod, the shock absorber assembly may also be restricted and cannot be flipped backward. In this case, the connecting seat can be pulled to extend the shock absorber assembly above the movable frame, so that the shock absorber is partially exposed above the movable frame, which is convenient for maintenance of the shock absorber.

[0077] The connecting seat is located at the upper end of the movable frame and further includes a fastening screw, which passes through the connecting seat from top to bottom and is screwed and fixed to the movable frame. The connecting operation is convenient and fast, and the disassembly is also fast.

[0078] The fixed frame is connected to a first connecting shaft, and the first connecting bracket is rotatably connected to the fixed frame via the first connecting shaft. After the connecting base is separated from the movable frame, the shock absorber can be flipped about the first connecting shaft toward the rear end of the unicycle, or the shock absorber can be rotated about the first connecting shaft and at least partially pulled upward from the movable frame, exposing the shock absorber. The first connecting shaft enables the rotatable installation of the first connecting bracket and also facilitates the rotation, flipping, or upward movement of the first connecting bracket.

[0079] In this technical solution, a first connecting shaft 61 is connected to the fixed frame 21. The first connecting bracket 6 is rotatably connected to the fixed frame 21 via the first connecting shaft 61. After the second end 52 is separated from the movable frame 22, the shock absorber 5 can be tilted toward the rear end of the unicycle about the first connecting shaft 61. The first connecting shaft is fixedly or rotationally connected to the fixed frame and serves as the central axis of rotation for the shock absorber and the first connecting bracket to tilt, achieving a rotational connection between the first connecting bracket 6 and the fixed frame and simplifying the connection structure. The first connecting shaft is perpendicular to the shock absorber.

[0080] In this technical solution, if Figure 7 As shown, a guide connector 63 is provided on the first connecting bracket 6, and a connecting portion 64 is connected to the guide connector 63, which can move on the guide connector 63. The moving direction of the connecting portion 64 is perpendicular to the first connecting shaft 61 and the extension and contraction direction of the shock absorber 5. The first end 51 is connected to the connecting portion 64, and the angle between the shock absorber 5 and the first connecting bracket 6 changes as the position of the connecting portion 64 on the guide connector 63 changes. Figure 7 As shown, the second end is directly or indirectly connected to the movable frame for rotation, and the connecting portion 64 is moved along the guide direction of the guide connecting member 63 to realize fixed connection between the first end and the first connecting bracket at different positions, thereby adjusting the inclination angle of the shock absorber and adjusting the shock absorption effect and shock absorption capacity of the shock absorber.

[0081] In the above solution, the guide connector 63 is generally a screw or a lead screw, and the connecting portion 64 is threadedly mounted on the guide connector 63. During adjustment, the guide connector 63 is rotated, and the connecting portion can move on the guide connector 63, thereby achieving installation of the first end and the first connecting bracket in different positions. The guide connector 63 is generally a screw or a lead screw, which can directly adjust the position of the connecting portion and also has a self-locking capability to prevent the connecting portion from moving on the guide connector 63 when the wheelbarrow is moving, thereby ensuring a secure connection between the first end and the first connecting bracket.

[0082] Of course, by adjusting the connection position between the first end and the first connecting bracket, the position of the shock absorber can be further adjusted after the shock absorber is flipped backward, which facilitates maintenance operations of the shock absorber.

[0083] In this technical solution, the second end 52 is connected to a second connecting shaft 81 that is parallel to the first connecting shaft 61. The second end 52 is detachably and rotatably connected to the movable frame 22 via the second connecting shaft 81. The second connecting shaft 81 provides a detachable and rotatable connection to the second end of the shock absorber and also serves as the rotation axis for the shock absorber to achieve shock absorption. This provides a simple structure, easy installation, and high strength.

[0084] In this technical solution, a connecting seat 8 is detachably fixed to the movable frame 22, and a second connecting shaft 81 is detachably and rotatably connected to the movable frame 22 via the connecting seat 8. The connecting seat realizes a direct or indirect detachable connection between the second connecting shaft and the movable frame. When the shock absorber needs to be flipped backward, the connecting seat 8 is removed from the movable frame and the second end is unlocked from the movable frame, allowing the shock absorber to flip backward.

[0085] In this technical solution, the second connecting bracket 7 is rotatably connected to the movable frame 22, and the second connecting bracket 7 is rotatably connected to the first connecting bracket 6. The connecting shaft that rotatably connects the second connecting bracket 7 to the movable frame 22 is coaxially arranged with the connecting shaft that detachably connects the second end 52 to the movable frame 22, ensuring that when the wheelbarrow is bumpy, the second connecting bracket and the first connecting bracket can be linked together, facilitating the expansion and contraction of the shock absorber to achieve shock absorption and buffering.

[0086] In one embodiment, Figure 9 As shown, the second connecting bracket 7 is connected to the movable frame at its end, which is sleeved on the first connecting shaft 81 and is rotatably connected to the movable frame via the second connecting shaft 81, thereby simplifying the connection structure and reducing the number of connecting parts. Of course, the second connecting bracket can also be connected to a separate rotating shaft and rotatably connected to the movable frame via the rotating shaft, and the rotating shaft and the second connecting shaft can be arranged coaxially.

[0087] A second connecting shaft is connected to the connecting base 8, and the end of the shock absorber near the movable frame and the second connecting bracket are both connected to the second connecting shaft. In one embodiment, the second connecting shaft realizes the rotational connection between the connecting base and the shock absorber, which has a simple connection structure and realizes the rotation of the shock absorber.

[0088] In order to facilitate the connection between the movable frame and the second connecting bracket, avoid the problem of position offset after connection, and solve the interference problem when the second connecting bracket is installed on the movable frame, and facilitate the connection between the movable frame and the second connecting shaft, a first limiting groove 25 and a second limiting groove 24 are provided on the movable frame. Figure 10 Therefore, the second limiting groove is located in the first limiting groove, the second connecting bracket is placed in the second limiting groove, and the connecting seat 8 is placed in the first limiting groove.

[0089] The second connecting bracket is rotatably connected to the first connecting shaft via the third connecting shaft 62 , and the third connecting shaft 62 is parallel to the first connecting shaft 61 .

[0090] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
