[0050] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0051] In the description of the present application, it should be understood that the terms "length", "width", "upper", "lower", "upward", "vertical", "horizontal", "bottom", "inside", "outside", "inner side", "outer side" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0052] Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0053] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0054] Mobile energy storage devices often have a pull rod assembly installed on the chassis to facilitate force application and pulling of the device.

[0055] In the prior art, a pull rod assembly is typically mounted on the side of the chassis. When the device is moved, the chassis is tilted, and the operator pulls the pull rod assembly to move the chassis with it. However, when transporting heavy equipment with the chassis tilted, this can put significant pressure on the operator's hands, hindering transportation. Furthermore, the pull rod assembly's limited flexibility prevents the operator from adjusting or changing the device's posture, causing significant inconvenience during transportation.

[0056] For example, a vertical pull rod assembly is often provided on the chassis or suitcase. When in use, the chassis can only be pushed or pulled by tilting the chassis. When the chassis is heavy, the human hand will be under greater pressure, which reduces the operator's comfort and convenience.

[0057] Therefore, the pull rod assembly of the present application further adds a second pull rod unit on the basis of the first pull rod unit, and designs a first pull rod structure, a sliding structure, a first switch mechanism and a transfer mechanism in the second pull rod unit. The switch structure controls the sliding structure to switch between a locked state and an unlocked state relative to the first pull rod structure, so that the transfer mechanism can be in a free state. The transfer mechanism enables the first pull rod unit to deflect relative to the second pull rod unit in a direction deviating from the first preset direction. The structure of this pull rod assembly is more flexible and changeable; when the weight of the box is heavy and is not suitable for tilted transportation, the box can be flipped over to achieve a more stable state, and at the same time, the first pull rod unit in the pull rod assembly is rotated to adapt to the posture of the box after flipping, so that the operator can pull the box in a more comfortable way, thereby improving the convenience of transportation.

[0058] In order to make the purpose, technical solutions and advantages of this application more clear, this application is further described in detail below with reference to the accompanying drawings and embodiments.

[0059] Please refer to Figures 1-5. An embodiment of the present application provides a pull rod assembly, which includes a first pull rod unit 1 and a second pull rod unit 2; the second pull rod unit 2 includes a first pull rod structure 22, a sliding structure 23, a first switch mechanism 21 and a transfer mechanism 24; the sliding structure 23 is slidably connected to the first pull rod structure 22 along a first preset direction X; the first switch mechanism 21 is connected between the first pull rod structure 22 and the sliding structure 23, so that the sliding structure 23 can switch between a locked state and an unlocked state relative to the first pull rod structure 22; the transfer mechanism 24 is connected between the sliding structure 23 and the first pull rod unit 1, so that the first pull rod unit 1 can deflect by a preset angle a relative to the sliding structure 23 in a direction deviating from the first preset direction X; wherein, when the sliding structure 23 is in a locked state relative to the first pull rod structure 22, the transfer mechanism 24 is in a restricted state; when the sliding structure 23 is in an unlocked state relative to the first pull rod structure 22, the transfer mechanism 24 can be in a free state.

[0060] Specifically, as shown in Figure 6, the first pull rod unit 1 may include at least one pull rod component 11. The first pull rod unit 1 may be telescopic, that is, the first pull rod unit 1 can be telescopically deformed in its length direction. The first pull rod unit 1 extends outward to increase the length. After extending outward, the first pull rod unit 1 has a preset extension length, which is convenient for the operator to grasp in a comfortable position or height. The first pull rod unit 1 contracts to shorten the length and is hidden for easy storage, so that the exterior of the chassis connected to it (that is, the mobile body 3 described below) is more beautiful.

[0061] The first pull rod unit 1 may also adopt a fixed structure, and the first pull rod unit 1 always has a preset length so that the operator can grasp it at any time.

[0062] The second tie rod unit 2 is connected to the first tie rod unit 1 . By designing the structure of the second tie rod unit 2 , the first tie rod unit 1 can be deflected in a direction away from the length direction of the first tie rod unit 1 .

[0063] Specifically, the first tie rod structure 22 is used to connect with the mobile body 3 described below, and the first tie rod structure 22 plays a connecting role between the first tie rod unit 1 and the second tie rod unit 2 .

[0064] The first pull rod structure 22 can be a rod-shaped structural member or a cylindrical structural member. A accommodating space can be opened inside the first pull rod structure 22. The accommodating space can be a hole-shaped structure (i.e., the first sliding hole 223 described below). The sliding structure 23 and the transfer mechanism 24 can both be installed in the accommodating space. In addition, the first pull rod unit 1 can also be accommodated in the accommodating space.

[0065] The sliding structure 23 is slidably connected to the first rod structure 22 , and the sliding structure 23 can slide relative to the first rod structure 22 along a first preset direction X, wherein the first preset direction X may be the length direction of the first rod structure 22 .

[0066] The sliding structure 23 may be a columnar structure. The central axis of the sliding structure 23 may be coaxial with the central axis of the first pull rod structure 22 or the central axis of the hole-shaped accommodation space thereon. One end of the sliding structure 23 is connected to the adapter mechanism 24 .

[0067] 3, 4 and 9, the adapter mechanism 24 is connected between the sliding structure 23 and the first pull rod unit 1. Through the adapter mechanism 24, the first pull rod unit 1 can be deflected relative to the sliding structure 23 within a preset angle a that deviates from the first preset direction X. It can be understood that the first pull rod unit 1 can rotate relative to the sliding structure 23 at the position connected to the adapter mechanism 24, and after rotating the preset angle a, it follows the second preset direction Y. That is, the second preset direction Y is set at a preset angle a with the first preset direction X. The range of the preset angle a can be 0°-120°. In actual applications, the preset angle a can be selected from 45°, 60°, 90° and 120°, etc.

[0068] It can be understood that the deflection of the first rod unit 1 relative to the sliding structure 23 means that the first rod unit 1 deflects relative to the first rod structure 22 connected to the sliding structure 23 .

[0069] The transfer mechanism 24 has a restricted state and a free state. As shown in Figures 2 and 7, when the transfer mechanism 24 is in the restricted state, the first pull rod unit 1 and the sliding structure 23 and the first pull rod structure 22 connected thereto cannot rotate; as shown in Figures 6, 9 and 10, when the transfer mechanism 24 is in the free state, the transfer mechanism 24 can make the first pull rod unit 1 deviate from the first preset direction X relative to the sliding structure 23 and the first pull rod structure 22 by a preset angle a; the restricted state and free state of the transfer mechanism 24 are controlled by the first switch mechanism 21.

[0070] As shown in Figure 5, the first switch mechanism 21 is connected between the first pull rod structure 22 and the sliding structure 23. The first switch mechanism 21 can control the sliding structure 23 to be in a locked state relative to the first pull rod structure 22. In the locked state, the transfer mechanism 24 is in a restricted state where it cannot rotate. In this state, the pull rod assembly can only use the first pull rod unit 1 for transportation operations, and the operator holds the first pull rod unit 1 to pull or push operations.

[0071] As shown in Figure 6, the first switch mechanism 21 can control the sliding structure 23 to be in an unlocked state relative to the first pull rod structure 22. In the unlocked state, the switching mechanism 24 is in a free state. In this state, the first pull rod unit 1 can cooperate with the second pull rod unit 2. The switching mechanism 24 can make the first pull rod unit 1 deflect relative to the sliding structure 23 and the second pull rod unit 2, so that the first pull rod unit 1 can be deflected. The first pull rod unit 1 realizes deflection or rotation through the second pull rod unit 2, so that after being connected with the mobile body 3, it can be deflected or rotated between the mobile body 3, so that it can have multiple pulling or pushing modes with the mobile body 3 to adapt to the different transportation state requirements of the mobile body 3.

[0072] The first switch mechanism 21 may adopt a button-type structure, a sliding unlocking structure, a rotating unlocking structure, etc., and may be adaptively designed according to the specific movement form between the sliding structure 23 and the first pull rod structure 22 .

[0073] For example, the mobile body 3 is placed on a horizontal plane, the length direction of the first pull rod structure 22 is along the vertical direction, the first preset direction X is the vertical direction (or perpendicular direction), and before starting the first switch mechanism 21, the sliding structure 23 is in a locked state, and the transfer mechanism 24 is in a restricted state. The first pull rod unit 1 cannot be deflected relative to the mobile body 3 in a direction deviating from the first preset direction X through the second pull rod unit 2.

[0074] As shown in Figures 11 and 12, when the mobile body 3 needs to be tilted and moved, the operator's hands will be under pressure when tilting, so the mobile body 3 is flipped 90° before moving. Before the mobile body 3 moves, the first switch mechanism 21 is started, and the sliding structure 23 is in an unlocked state. Therefore, the sliding structure 23 can slide relative to the first pull rod structure 22. When the sliding structure 23 slides to the preset position, the adapter mechanism 24 will be in a free state. At this time, the first pull rod unit 1 can be deflected relative to the mobile body 3 in a direction deviating from the first preset direction X through the adapter mechanism 24. For example, the first pull rod unit 1 rotates toward the rear of the forward direction with the adapter mechanism 24 as the rotation center. When it rotates 45° (the preset angle a is 45°), the first pull rod unit 1 will form a preset angle a of 45° with the horizontal plane. When the first pull rod unit 1 is 45° with the horizontal plane, it pulls the flipped mobile body 3. At this time, the operator's hand is no longer under pressure from the mobile body 3, making it more convenient and labor-saving for the operator to pull the mobile body 3. It should be noted that after the mobile body 3 is flipped 90°, the mobile body 3 can still move smoothly.

[0075] In this embodiment, the pull rod assembly has a first pull rod unit 1 and a second pull rod unit 2. The first pull rod unit 1 is mainly used for the operator to hold it, and the second pull rod unit 2 is mainly used to deflect the first pull rod unit 1 away from the first preset direction X, so that the first pull rod unit 1 can be adaptively rotated to adapt to the convenient use of the mobile body 3 after changing its posture.

[0076] In addition, by setting up the first switching mechanism 21, the control of the movement of the first pull rod unit 1 relative to the second pull rod unit 2 is achieved, so that the pull rod assembly has at least two application states to adapt to the posture change of the chassis or box (mobile body). The operator can choose to use only the first pull rod unit according to the weight of the chassis or box, or choose to further start the second pull rod unit. The structure of the pull rod assembly is more flexible, the transportation process is more convenient, the operator's comfort and experience are enhanced, and the human-computer interaction is improved.

[0077] In one embodiment, referring to Figures 4, 5 and 9, the first pull rod structure 22 is provided with a first sliding hole 223 along the first preset direction X, and the sliding structure 23 is slidingly connected in the first sliding hole 223; when the sliding structure 23 is in a locked state relative to the first pull rod structure 22, the sliding structure 23 is hidden in the first sliding hole 223, and the adapter mechanism 24 is accommodated in the first sliding hole 223 to be in a restricted state; when the sliding structure 23 is in an unlocked state relative to the first pull rod structure 22, the sliding structure 23 can at least partially extend out of the first sliding hole 223 to allow the adapter mechanism 24 to be in a free state.

[0078] Specifically, the first pull rod structure 22 is cylindrical, and the first sliding hole 223 is opened along the central axis of the first pull rod structure 22. The sliding structure 23 can move back and forth along its central axis in the first sliding hole 223. Since the first pull rod unit 1 is connected to the sliding structure 23 through the adapter mechanism 24, it can be understood that the first pull rod unit 1 can be at least partially accommodated in the first sliding hole 223, so that the first pull rod unit 1 can be hidden inside the first pull rod structure 22.

[0079] The transfer mechanism 24 may adopt a hinge structure, which includes a hinge shaft, and the end of the pull rod component 11 in the first pull rod unit 1 is rotationally connected to the sliding structure 23 via the hinge shaft.

[0080] 2 , 5 , 6 , and 7 , when the sliding structure 23 is in a locked state relative to the first rod structure 22, the sliding structure 23 and the adapter mechanism 24 are both located in the first sliding hole 223. Therefore, the hole wall of the first sliding hole 223 limits the rotation of the adapter mechanism 24, so that the first rod unit 1 cannot rotate through the adapter mechanism 24. With reference to FIG9 and FIG10 , when the sliding structure 23 is in an unlocked state relative to the first rod structure 22, the sliding structure 23 and the first rod unit 1 can slide back and forth in the first sliding hole 223. When sliding to a preset position, that is, when the length of the first rod unit 1 extending out of the first sliding hole 223 is sufficient, the adapter mechanism 24 is exposed outside the first sliding hole 223. At this time, there is no restriction on the adapter mechanism 24 by the hole wall of the first sliding hole 223. The adapter mechanism 24 is in a free state, and the first rod unit 1 can rotate relative to the sliding structure 23 through the adapter mechanism 24.

[0081] In this embodiment, by controlling the adapter mechanism 24 inside or outside the first sliding hole 223, the switching of the adapter mechanism 24 between the restricted state and the free state is achieved. The structural design is compact, simple, easy to implement, and easy to operate.

[0082] In one embodiment, referring to Figures 3, 4 and 5, the first switch mechanism 21 includes a first locking structure 212 and a second locking structure 221. The first locking structure 212 is movably connected to the sliding structure 23, and the second locking structure 221 is connected to the first pull rod structure 22. The first locking structure 212 can be connected to the second locking structure 221 so that the sliding structure 23 is in a locked state relative to the first pull rod structure 22; the first locking structure 212 can be disengaged from the second locking structure 221 so that the sliding structure 23 is in an unlocked state relative to the first pull rod structure 22.

[0083] Specifically, the first locking structure 212 is movably connected to the sliding structure 23 in a manner including sliding or rotating, etc. The first locking structure 212 can be a protruding structure, and the second locking structure 221 can also be a protruding structure. The two protruding structures limit the relative movement of the sliding structure 23 and the first pull rod structure 22 by blocking. At this time, the first locking structure 212 can be connected to or disengaged from the second locking structure 221 by sliding or rotating; the second locking structure 221 can also adopt a groove structure or a hole structure, and the relative movement of the sliding structure 23 and the first pull rod structure 22 is limited by plugging the protruding structure and the hole structure. At this time, the first locking structure 212 can be connected to or disengaged from the second locking structure 221 by sliding.

[0084] In this embodiment, the movement of the first locking structure 212 relative to the sliding structure 23 can be manual or automatic, and can be specifically designed according to the specific usage scenario and cost budget; this first switch mechanism realizes the locking and unlocking between the sliding structure 23 and the first pull rod structure 22 by connecting and disconnecting the first locking structure 212 and the second locking structure 221. It has a simple structure and flexible and convenient control.

[0085] In one embodiment, referring to FIG. 4 and FIG. 5 , the first switch mechanism 21 further includes a first elastic structure 214 , which is connected between the first locking structure 212 and the sliding structure 23 , so that the first locking structure 212 moves relative to the sliding structure 23 to connect with the second locking structure 221 .

[0086] Specifically, the first elastic structure 214 can be a spring member. When the first locking structure 212 is slidingly connected to the sliding structure 23, the spring member can be a coil spring; when the first locking structure 212 is rotationally connected to the sliding structure 23, the spring member can be a torsion spring.

[0087] During use, an external force presses or rotates the first locking structure 212, causing the first locking structure 212 to disengage from the second locking structure 221 to achieve the purpose of unlocking. At the same time, the first elastic structure 214 is compressed to accumulate elastic force. During locking, when the first locking structure 212 and the second locking structure 221 are close to each other, the first elastic structure 214 releases the elastic force to connect the first locking structure 212 and the second locking structure 221 to achieve the purpose of locking.

[0088] In this embodiment, by providing the first elastic structure 214, the automatic locking process of the first locking structure 212 and the second locking structure 221 can be achieved, which reduces manual operation, makes the operation more labor-saving and convenient, and is conducive to improving work efficiency.

[0089] In one embodiment, as shown in Figures 4 and 5, the first locking structure 212 includes a first locking body slidably connected to the sliding structure 23, and the second locking structure 221 includes a locking hole opened on the first pull rod structure 22, and the first locking body is plugged into the locking hole.

[0090] Specifically, the first locking body is columnar, and a mounting hole is provided on the sliding structure 23 perpendicular to the first preset direction X. The first locking body is slidably connected to the mounting hole. A locking hole is provided on the first pull rod structure 22 at a position opposite to the first locking body. The first locking body extends or retracts in and out of the mounting hole to be plugged into or disengaged from the locking hole, so that the first pull rod structure 22 and the sliding structure 23 are locked or unlocked.

[0091] In one embodiment, as shown in Figures 4 and 5, two first locking bodies can be provided, and the two first locking bodies can be symmetrically arranged on both sides of the central axis of the sliding structure 23. Correspondingly, two locking holes are provided, and one first locking body is plugged into and matched with one locking hole; correspondingly, two first elastic structures 214 are provided, and one first elastic structure 214 is connected between one first locking body and the sliding structure 23.

[0092] In this embodiment, by setting two first locking structures 212, two locking holes and two first elastic structures 214, and making the corresponding combinations between the above-mentioned structural parts symmetrically arranged on both sides of the central axis of the sliding structure 23, the stability of the locking between the sliding structure 23 and the first pull rod structure 22 is improved, and the locking is more firm and reliable.

[0093] In one embodiment, as shown in Figures 1-5, the first switch mechanism 21 also includes a second elastic structure 211, which is connected between the sliding structure 23 and the first pull rod structure 22, so as to push the sliding structure 23 to move relative to the first pull rod structure 22 when the sliding structure 23 is in an unlocked state.

[0094] Specifically, the second elastic structure 211 can adopt a coil spring, the central axis direction of the coil spring is along the first preset direction X, and the second elastic structure 211 can be connected between the end of the sliding structure 23 in the first sliding hole 223 and the bottom of the first sliding hole 223 of the first pull rod structure 22.

[0095] When the sliding structure 23 is in a locked state relative to the first pull rod structure 22, the second elastic structure 211 is in a compressed state to accumulate elastic force; when the first locking structure 212 is disengaged from the second locking structure 221, the sliding structure 23 is in an unlocked state relative to the first pull rod structure 22. At this time, the second elastic structure 211 releases the elastic force, so that the sliding structure 23 and the first pull rod unit 1 connected thereto move along the first preset direction X toward the outside of the first sliding hole 223.

[0096] In this embodiment, the second elastic structure 211 promotes the movement of the sliding structure 23 and the first pull rod unit 1. The elastic force of the second elastic structure 211 can make the sliding structure 23 and the first pull rod unit 1 eject a certain distance. By setting the second elastic structure 211, on the one hand, the first pull rod unit 1 can automatically move independently relative to the first pull rod structure 22 first. On the other hand, it can serve as a prompt to unlock the operator, making the operation more convenient and humane.

[0097] In one embodiment, as shown in Figures 1-5, the first switch mechanism 21 also includes a button structure 213, which is slidably connected to the first pull rod structure 22 and can be connected to the first locking structure 212 to disengage the first locking structure 212 from the second locking structure 221.

[0098] Specifically, the button structure 213 forms a pressing portion on the outside of the first pull rod structure 22. When there is only one first locking body, there can be only one pressing portion. By moving the pressing portion, the first locking structure 212 (first locking body) is pushed to move so as to disengage from the second locking structure 221 (locking hole); when there are two first locking bodies, there are correspondingly two pressing portions, and the two pressing portions move toward or away from each other to push the two first locking bodies to move respectively so that the locking bodies are disengaged from the locking holes.

[0099] The button structure 213 is located at the end of the first pull rod structure 22 facing away from the first pull rod unit 1, that is, the button structure 213 is located at the end of the first pull rod structure 22 connected to the movable body 3. Optionally, the button structure 213 can be located on the end face of the first pull rod structure 22, or on the side of the end of the first pull rod structure 22, and is also reasonably arranged according to the installation space.

[0100] In this embodiment, by providing the button structure 213 , control can be easily performed outside the first pull rod structure 22 , making the operation more convenient.

[0101] In one embodiment, as shown in Figures 4 and 5, the first switch mechanism 21 also includes a fourth elastic structure 215, which is connected between the button structure 213 and the first pull rod structure 22 (or the movable body 3) so that the button structure 213 can move back to its initial position through the fourth elastic structure 215 after being pressed.

[0102] In this embodiment, the fourth elastic structure 215 can be a coil spring. By providing the fourth elastic structure 215, the button structure 213 can automatically return to its initial position, making the button structure 213 more convenient to use.

[0103] In one embodiment, referring to Figures 3, 4 and 5, the pull rod assembly further includes a limiting mechanism, which is connected between the sliding structure 23 and the first pull rod structure 22. The limiting mechanism can lock the sliding structure 23 to the first pull rod structure 22 after the transfer mechanism 24 is in a free state.

[0104] In this embodiment, the limiting structure is mainly used to control the sliding distance of the sliding structure 23 and the first pull rod unit 1 relative to the first pull rod structure 22 and the first sliding hole 223, and can fix the position of the sliding structure 23 relative to the first pull rod structure 22 when the adapter mechanism 24 is exposed outside the first sliding hole 223 and is in a free state, thereby limiting the sliding structure 23.

[0105] In one embodiment, referring to Figures 3, 4 and 5, the limiting mechanism includes a first limiting structure 25 and a second limiting structure 222. The first limiting structure 25 is movably connected to the sliding structure 23, and the second limiting structure 222 is connected to the first pull rod structure 22. The first limiting structure 25 can be connected to the second limiting structure 222 to limit the movement of the sliding structure 23 relative to the first pull rod structure 22.

[0106] Specifically, the first limiting structure 25 is movably connected to the sliding structure 23 in a manner including sliding or rotating, etc. The first limiting structure 25 can be a protruding structure, and the second limiting structure 222 can also be a protruding structure. The two protruding structures limit the relative movement of the sliding structure 23 and the first pull rod structure 22 by blocking. At this time, the first limiting structure 25 can be abutted or disengaged from the second limiting structure 222 by sliding or rotating; the second limiting structure 222 can also adopt a groove structure or a hole structure, and the relative movement of the sliding structure 23 and the first pull rod structure 22 is limited by plugging the protruding structure and the hole structure. At this time, the first limiting structure 25 can be plugged into or disengaged from the second limiting structure 222 by sliding.

[0107] In this embodiment, the movement of the first limiting structure 25 relative to the sliding structure 23 can be manual or automatic, and can be specifically designed according to the specific usage scenario and cost budget; by connecting and disconnecting the first limiting structure 25 and the second limiting structure 222, the sliding structure 23 and the first pull rod structure 22 are locked and unlocked to limit the moving distance of the sliding structure 23 and the first pull rod unit 1 relative to the first pull rod structure 22. The structure is simple and the control is flexible and convenient.

[0108] In one embodiment, as shown in Figures 4 and 5, the limiting mechanism also includes a third elastic structure 26, which is connected between the first limiting structure 25 and the sliding structure 23, so that the first limiting structure 25 moves relative to the sliding structure 23 to connect with the second limiting structure 222.

[0109] Specifically, the third elastic structure 26 may be a spring member, and the spring member may be a coil spring.

[0110] When in use, the wall of the first sliding hole 223 presses the first limiting structure 25, so that the third elastic structure 26 is compressed to accumulate elastic force; when locked, when the first limiting structure 25 and the second limiting structure 222 are close to each other, the third elastic structure 26 releases the elastic force, so that the first limiting structure 25 and the second limiting structure 222 are connected, thereby achieving the purpose of the limiting sliding structure.

[0111] In this embodiment, by providing the third elastic structure 26, the automatic locking process of the first limiting structure 25 and the second limiting structure 222 can be achieved, which reduces manual operation, makes the operation more labor-saving and convenient, and is conducive to improving work efficiency.

[0112] In one embodiment, as shown in FIG. 4 , the first limiting structure 25 includes a first limiting body, and the second limiting structure 222 includes a limiting hole formed on the first pull rod structure 22 , and the first limiting body is plugged into the limiting hole.

[0113] In this embodiment, the first limiting body is columnar, and a mounting hole is provided on the sliding structure 23 perpendicular to the first preset direction X. The first limiting body is slidably connected to the mounting hole. A limiting hole is provided on the first pull rod structure 22 at a position opposite to the first limiting body. The first limiting body extends or retracts in and out of the mounting hole to be plugged into or disengaged from the limiting hole, so that the first pull rod structure 22 and the sliding structure 23 are locked or unlocked.

[0114] In one embodiment, referring to Figures 6-10 , the first rod unit 1 can be telescopically deformed along a first preset direction X.

[0115] Specifically, the first rod unit 1 includes a plurality of rod components 11 connected end to end, two adjacent rod components 11 are slidably connected, and among any two adjacent rod components 11, the rod component 11 away from the second rod unit 2 can be hidden in the rod component 11 close to the second rod unit 2.

[0116] The rod component 11 may be cylindrical, and the rod components 11 are nested in sequence, so that the first rod unit 1 can be extended and lengthened and contracted and shortened.

[0117] In this embodiment, the first rod unit 1 can be extended and deformed to enable the operator to hold it at a relatively comfortable height to pull the mobile body 3. The first rod unit 1 can be used independently to meet the operator's usage requirements. The first rod unit 1 can also be used in conjunction with the second rod unit 2. The first switch mechanism 21 activates the switching mechanism 24, and the first rod unit 1 can be rotated through the switching mechanism 24 to enable the mobile body 3 connected thereto to change its orientation. This allows the first rod unit 1 to pull or push the mobile body 3 without pressure, making it more labor-saving and convenient for the operator to use the rod assembly.

[0118] In one embodiment, as shown in FIG. 7-10 , a first accommodating space is formed in the first pull rod structure 22 , and the first pull rod unit 1 can be hidden in the first accommodating space, and the first pull rod unit 1 can also extend out of the first accommodating space.

[0119] Specifically, the first accommodating space may adopt the first sliding hole 223 in the above embodiment, so that the sliding structure 23 , the switching mechanism 24 and the first pull rod unit 1 can all be accommodated in the first sliding hole 223 .

[0120] In this embodiment, by opening a first accommodating space or a first sliding hole 223 on the first pull rod structure 22, the first pull rod structure 22 can hide the first pull rod unit 1, which is beneficial to reducing the volume of the pull rod assembly, saving space, and improving the external aesthetics of the pull rod assembly.

[0121] In one embodiment, as shown in FIG. 3 and FIG. 4 , the first rod unit 1 has a second switch structure 13 , and the second switch structure 13 can control the telescopic deformation of the first rod unit 1 .

[0122] Specifically, the second switch structure 13 can adopt a push-button switch or a rotary switch structure; the second switch structure 13 is connected between the internal pull rod component 11 and the external pull rod component 11 in the first pull rod unit 1. By operating the second switch structure 13, the internal pull rod component 11 and the external pull rod component 11 are unlocked, so that the internal pull rod component 11 can be extended outward in turn, thereby realizing the extension of the first pull rod unit 1.

[0123] The first rod unit 1 is also provided with a handle 12 for the operator to hold. The second switch structure 13 can be set on the handle 12 or on the side of the handle 12 to facilitate the operator to hold it and unlock the first rod unit 1 through the second switch structure 13.

[0124] An embodiment of the present application further provides a mobile device, as shown in FIG. 11 and FIG. 12 , the mobile device includes a mobile body 3 and the pull rod assembly in the above embodiment, and a first pull rod structure 22 is connected to the mobile body 3 .

[0125] Specifically, the mobile body 3 includes at least a box body, the first pull rod structure 22 is connected to the box body, a second accommodating space (not shown in the figure) can be opened on the box body, and the first pull rod structure 22 is accommodated in the second accommodating space. The box body serves the purpose of hiding the first pull rod structure 22, making the exterior of the box body more beautiful.

[0126] Among them, in combination with Figure 11, the mobile body 3 also includes a first mobile structure 31, which is located at the bottom of the box body to support the box body and can drive the box body to move. The first mobile structure 31 can adopt a wheel body, and the wheel body can adopt a universal wheel; Figure 11 shows a schematic diagram of the mobile body 3 in an upright state. By tilting the first pull rod unit 1, the mobile body 3 can be tilted and pulled for moving transportation.

[0127] As shown in Figure 11, the mobile body 3 also includes a second mobile structure 32, which is located on the side of the box body and on the side surface facing the ground after the box body is flipped over; as shown in Figure 12, the second mobile structure 32 is mainly used to support the box body after the box body is flipped over, and to drive the box body to move; Figure 12 shows the usage mode after the mobile body 3 is flipped 90 degrees. After flipping 90 degrees, the first mobile structure 31 and the second mobile structure 32 are both supported on the ground, and the first switch mechanism 21 is started. The first pull rod unit 1 is rotated through the adapter mechanism 24 in the second pull rod unit 2 to reach the state shown in Figure 12, so as to facilitate the operator to pull the mobile body 3 for transportation. In this state, the first pull rod unit 1 will not be subjected to the tilting pressure of the mobile body 3, and the moving process is more labor-saving and convenient.

[0128] In this embodiment, the mobile device arranges the pull rod assembly in the above embodiment on the box body, so that the pull rod assembly has a first pull rod unit 1 and a second pull rod unit 2. The first pull rod unit 1 is mainly used for the operator to hold it, and the second pull rod unit 2 is mainly used to deflect the first pull rod unit 1 away from the first preset direction X, so that the first pull rod unit 1 can be adaptively rotated to adapt to the convenient use of the mobile body 3 after changing its posture; this pull rod assembly can adjust the box body to a more stable posture, and the operator can pull the box in a more comfortable way.

[0129] In addition, by setting up the first switching mechanism 21, the control of the movement of the first pull rod unit 1 relative to the second pull rod unit 2 is achieved, so that the pull rod assembly has at least two application states to adapt to the posture change of the chassis or box (mobile body). The operator can choose to use only the first pull rod unit according to the weight of the chassis or box, or choose to further start the second pull rod unit. The structure of the pull rod assembly is more flexible, the transportation process is more convenient, the operator's comfort and experience are enhanced, and the human-computer interaction is improved.

[0130] In one embodiment, as shown in Figures 11 and 12, the first switch mechanism 21 is snap-connected to the box. Since the first pull rod structure 22 is connected to the box, the first switch mechanism 21 can also be connected to the box. The first switch mechanism 21 can be connected to the box by a snap-connection method, which can include a sliding limit plug-in connection, an elastic locking connection, etc.

[0131] In this embodiment, since the first pull rod structure 22 is connected to the box body, the first switch mechanism 21 can be directly connected between the box body and the sliding structure 23. Similarly, by controlling the first switch mechanism 21, the sliding structure 23 can be placed in a locked state relative to the first pull rod structure 22 and the box body, and the sliding structure 23 can also be placed in an unlocked state relative to the first pull rod structure 22 and the box body.

These descriptions are intended only to explain the principles of the present application and should not be construed in any way as limiting the scope of protection of the present application.
