The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0032] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0033] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0034] Mobile energy storage devices often have a pull rod assembly installed on the chassis, which facilitates the application of force and pulling of the device.
[0035] In the related art, the rod assembly is generally installed on the side of the chassis. When the equipment is moved, the chassis will be tilted, and the operator pulls the rod assembly to make the chassis move with it. However, when the weight of the equipment is heavy, the tilted box transportation will put a lot of pressure on the hands, causing obstacles to the operator's transportation. However, due to the poor flexibility of the rod assembly, the posture of the equipment cannot be adjusted or changed, causing many inconveniences during transportation.
[0036] For example, a pull rod assembly is often provided on the body of a chassis or a suitcase. When in use, the body can only be pushed or pulled by tilting the chassis. When the body is heavy, the human hand will be under greater pressure, which reduces the operator's comfort and makes it less convenient to use.
[0037] Therefore, the tie rod assembly of the present application further adds a second tie rod unit on the basis of the first tie rod unit, and designs a first tie rod structure, a sliding structure, a first switch mechanism and a transfer mechanism in the second tie rod unit. The switch structure controls the sliding structure to switch between a locked state and an unlocked state relative to the first tie rod structure, so that the transfer mechanism can be in a free state. The transfer mechanism enables the first tie rod unit to deflect relative to the second tie rod unit in a direction deviating from the first preset direction. The structure of the tie 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. At the same time, the first tie rod unit in the tie rod assembly can be 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.
[0038] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0039] See also Figure 1-5As shown, 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 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.
[0040] Specifically, combined Figure 6 As shown, the first rod unit 1 may include at least one rod component 11. The first rod unit 1 may be telescopic, that is, the first rod unit 1 can be telescopically deformed in the length direction thereof. The first rod unit 1 extends outward to increase the length. After being extended, the first rod unit 1 has a preset extension length, which is convenient for the operator to grasp in a comfortable position or height. The first rod unit 1 contracts to shorten the length and is hidden for easy storage, thereby making the exterior of the chassis connected thereto (i.e., the mobile body 3 described below) more beautiful.
[0041] 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.
[0042] The second tie rod unit 2 is connected to the first tie rod unit 1 , and the structure of the second tie rod unit 2 is designed so that the first tie rod unit 1 can be deflected in a direction away from the length direction of the first tie rod unit 1 .
[0043] Specifically, the first tie rod structure 22 is used to be connected to the mobile body 3 described below, and the first tie rod structure 22 serves as a connection between the first tie rod unit 1 and the second tie rod unit 2 .
[0044] 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.
[0045] 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 .
[0046] The sliding structure 23 may be a columnar structure, the central axis of the sliding structure 23 may be coaxially arranged with the central axis of the first pull rod structure 22 or the central axis of the hole-shaped accommodation space thereon, and one end of the sliding structure 23 is connected to the switching mechanism 24 .
[0047] Reference Figure 3 As shown, the adapter mechanism 24 is connected between the sliding structure 23 and the first rod unit 1. Through the adapter mechanism 24, the first 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 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 moves along the second preset direction Y. That is to say, 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.
[0048] 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 .
[0049] The switching mechanism 24 has a restricted state and a free state, referring to Figure 2 and Figure 7 As shown, when the switching mechanism 24 is in the restricted state, the first tie rod unit 1 and the sliding structure 23 and the first tie rod structure 22 connected thereto cannot rotate; Figure 6 and Fig. 9 and Fig.10 As shown, when the adapter mechanism 24 is in a free state, the adapter mechanism 24 can cause the first rod unit 1 to deviate from the first preset direction X by a preset angle a relative to the sliding structure 23 and the first rod structure 22; the restricted state and free state of the adapter mechanism 24 are controlled by the first switch mechanism 21.
[0050] Combination Figure 5 As shown, 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 for pulling or pushing operations.
[0051] Combination Figure 6 As shown, 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 a variety of pulling or pushing modes with the mobile body 3, so as to adapt to different transportation state requirements of the mobile body 3.
[0052] 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 .
[0053] 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.
[0054] Combination Fig.11 and Fig.12 As shown, when the mobile body 3 needs to be tilted and moved, since the operator's hands will be under pressure when tilting, 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 switching 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 switching mechanism 24. For example, the first pull rod unit 1 rotates toward the rear of the forward direction with the switching 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.
[0055] In this embodiment, the rod assembly includes a first rod unit 1 and a second rod unit 2. The first rod unit 1 is mainly used for the operator to hold, and the second rod unit 2 is mainly used to deflect the first rod unit 1 away from the first preset direction X, so that the first rod unit 1 can be adaptively rotated to accommodate the convenient use of the mobile body 3 after changing its posture.
[0056] In addition, by setting the first switch mechanism 21, the control of the movement of the first rod unit 1 relative to the first rod unit 1 is realized, so that the 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 rod unit according to the weight of the chassis or box, or choose to further start the second rod unit. The structure of the 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.
[0057] In one embodiment, referring to Figure 4 and Figure 5 and Fig. 9 As shown, 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 slidably 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 make the adapter mechanism 24 in a free state.
[0058] Specifically, the first rod structure 22 is cylindrical, and the first sliding hole 223 is opened along the central axis of the first rod structure 22. The sliding structure 23 can reciprocate along the central axis in the first sliding hole 223. Since the first rod unit 1 is connected to the sliding structure 23 through the adapter mechanism 24, it can be understood that the first rod unit 1 can be at least partially accommodated in the first sliding hole 223, so that the first rod unit 1 can be hidden inside the first rod structure 22.
[0059] The switching 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.
[0060] Combination Figure 2 , Figure 5 , Figure 6 ,and Figure 7As shown, when the sliding structure 23 is in a locked state relative to the first pull rod structure 22, the sliding structure 23 and the switching mechanism 24 are both located in the first sliding hole 223, so the hole wall of the first sliding hole 223 limits the rotation of the switching mechanism 24, so that the first pull rod unit 1 cannot be rotated through the switching mechanism 24; Fig. 9 and Fig.10 When the sliding structure 23 is in an unlocked state relative to the first pull rod structure 22, the sliding structure 23 and the first pull 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 pull rod unit 1 extending outside 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, and the adapter mechanism 24 is in a free state. The first pull rod unit 1 can rotate relative to the sliding structure 23 through the adapter mechanism 24.
[0061] In this embodiment, by controlling the adapter mechanism 24 in the first sliding hole 223 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.
[0062] In one embodiment, referring to Figure 3 and Figure 4 and Figure 5 As shown, 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.
[0063] 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 may be a protruding structure, and the second locking structure 221 may 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 abutted against or disengaged from the second locking structure 221 by sliding or rotating; the second locking structure 221 may 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 the plug-in connection between the protruding structure and the hole structure. At this time, the first locking structure 212 can be plugged into or disengaged from the second locking structure 221 by sliding.
[0064] 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; the first switch mechanism realizes the locking and unlocking between the sliding structure 23 and the first pull rod assembly by connecting and disconnecting the first locking structure 212 with the second locking structure 221, and has a simple structure and flexible and convenient control.
[0065] In one embodiment, referring to Figure 4 and Figure 5 As shown, 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 be connected with the second locking structure 221 .
[0066] Specifically, the first elastic structure 214 can be a spring member. When the first locking structure 212 is slidably 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.
[0067] When in use, an external force presses or rotates the first locking structure 212, so that the first locking structure 212 and the second locking structure 221 are disengaged to achieve the purpose of unlocking. At the same time, the first elastic structure 214 is compressed to accumulate elastic force. When 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 with the second locking structure 221 to achieve the purpose of locking.
[0068] 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.
[0069] In one embodiment, referring to Figure 4 and Figure 5 As shown, 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 and matched with the locking hole.
[0070] Specifically, the first locking body is columnar, and a mounting hole is opened on the sliding structure 23 in a direction perpendicular to the first preset direction X. The first locking body is slidably connected in the mounting hole. A locking hole is opened in the position of the first pull rod structure 22 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.
[0071] In one embodiment, referring to Figure 4 and Figure 5 As shown, 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 a first locking body and the sliding structure 23.
[0072] In this embodiment, two first locking structures 212, two locking holes and two first elastic structures 214 are provided, and the corresponding combinations of the above-mentioned structural parts can be symmetrically arranged on both sides of the central axis of the sliding structure 23 to improve the stability of the locking between the sliding structure 23 and the first pull rod structure 22, and the locking is more firm and reliable.
[0073] In one embodiment, referring to Figure 1-5 As shown, the first switch mechanism 21 further 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.
[0074] Specifically, the second elastic structure 211 can be 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.
[0075] 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 to allow the sliding structure 23 and the first pull rod unit 1 connected thereto to move along the first preset direction X toward the outside of the first sliding hole 223.
[0076] 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 relative to the first pull rod structure 22 first, and on the other hand, it can serve as a prompt to unlock the operator, making the operation more convenient and user-friendly.
[0077] In one embodiment, referring to Figure 1-5 As shown, the first switch mechanism 21 further 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 .
[0078] 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. The pressing portion is moved to push the first locking structure 212 (first locking body) 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.
[0079] The button structure 213 is located at the end of the first rod assembly facing away from the first rod unit 1, that is, the button structure 213 is located at the end of the first rod structure 22 connected to the movable body 3. Optionally, the button structure 213 can be located on the end face of the first rod structure 22, or on the side of the end of the first rod structure 22, and is also reasonably arranged according to the installation space.
[0080] In this embodiment, by providing the button structure 213 , it is possible to conveniently control the outside of the first pull rod structure 22 , making the operation more convenient.
[0081] In one embodiment, referring to Figure 4 and Figure 5 As shown, 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 the initial position through the fourth elastic structure 215 after being pressed.
[0082] 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.
[0083] In one embodiment, referring to Figure 3 and Figure 4 and Figure 5 As shown, 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.
[0084] 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.
[0085] In one embodiment, referring to Figure 3 and Figure 4 and Figure 5 As shown, 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.
[0086] 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 may be a protruding structure, and the second limiting structure 222 may 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 against or disengaged from the second limiting structure 222 by sliding or rotating; the second limiting structure 222 may 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.
[0087] 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 with the second limiting structure 222, the sliding structure 23 and the first pull rod assembly 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.
[0088] In one embodiment, referring to Figure 4 and Figure 5 As shown, the limiting mechanism further includes a third elastic structure 26 , which is connected between the first limiting structure 25 and the sliding structure 23 , so that the second limiting structure 222 moves relative to the sliding structure 23 to be connected with the second limiting structure 222 .
[0089] Specifically, the third elastic structure 26 may be a spring member, and the spring member may be a coil spring.
[0090] When in use, the hole 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 to achieve the purpose of the limiting sliding structure.
[0091] 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.
[0092] In one embodiment, referring to Figure 4 As shown, the first limiting structure 25 includes a first limiting body, and the second limiting structure 222 includes a limiting hole opened on the first pull rod structure 22, and the first limiting body is plugged into and matched with the limiting hole.
[0093] In this embodiment, the first limiting body is columnar, and a mounting hole is opened on the sliding structure 23 in a direction perpendicular to the first preset direction X. The first limiting body is slidably connected in the mounting hole. A limiting hole is opened 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.
[0094] In one embodiment, referring to Figure 6-10 As shown, the first rod unit 1 can be telescopically deformed along the first preset direction X.
[0095] 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.
[0096] 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 elongated, and contracted and shortened.
[0097] 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 extended and retracted independently to meet the operator's use requirements. The first rod unit 1 can also be used in conjunction with the second rod unit 2. The first switch mechanism 21 starts the switching mechanism 24, and the first rod unit 1 can be rotated through the switching mechanism 24, so that the mobile body 3 connected thereto can change its orientation, thereby enabling 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.
[0098] In one embodiment, referring to Figure 7-10 As shown, a first accommodating space is formed in the first rod structure 22 , and the first rod unit 1 can be hidden in the first accommodating space, and the first rod unit 1 can also extend out of the first accommodating space.
[0099] 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 .
[0100] In this embodiment, by opening a first accommodating space or a first sliding hole 223 on the first tie rod structure 22, the first tie rod structure 22 can hide the first tie rod unit 1, which is beneficial to reducing the volume of the tie rod assembly, saving space, and improving the external aesthetics of the tie rod assembly.
[0101] In one embodiment, referring to Figure 3 and Figure 4 As shown, 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 .
[0102] 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 rod component 11 and the external rod component 11 in the first rod unit 1. By operating the second switch structure 13, the internal rod component 11 and the external rod structure are unlocked, so that the internal rod component 11 can be extended outward in turn, thereby realizing the extension of the first rod unit 1.
[0103] The first rod unit 1 is also provided with a handle 12 for the operator to hold. The second switch structure 13 can be arranged 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.
[0104] The present application also provides a mobile device, referring to Fig.11 and Fig.12 As shown, the mobile device includes a mobile body 3 and the pull rod assembly in the above embodiment, and the first pull rod structure 22 is connected to the mobile body 3.
[0105] Specifically, the mobile body 3 at least includes 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 hides the first pull rod structure 22, making the exterior of the box body more beautiful.
[0106] Among them, combined Fig.11 As shown, 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 be a wheel body, and the wheel body can be a universal wheel; Fig.11 The schematic diagram shows the mobile body 3 in an upright state. The mobile body 3 can be tilted and pulled to be moved and transported by tilting the first pull rod unit 1 .
[0107] Combination Fig.11 As shown, the mobile body 3 also includes a second mobile structure 32, which is located at the side of the box body and at a side surface facing the ground after the box body is turned over; Fig.12 As shown, the second moving structure 32 is mainly used to support the box body after the box body is turned over, and can drive the box body to move; Fig.12 The figure shows the use 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, the first switch mechanism 21 is started, and the first pull rod unit 1 is rotated through the switching mechanism 24 in the second pull rod unit 2 to achieve Fig.12 The state shown makes it convenient for 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.
[0108] In this embodiment, the mobile device arranges the rod assembly in the above embodiment on the box body, so that the rod assembly has a first rod unit 1 and a second rod unit 2. The first rod unit 1 is mainly used for the operator to hold, and the second rod unit 2 is mainly used to deflect the first rod unit 1 away from the first preset direction X, so that the first rod unit 1 can be adaptively rotated to accommodate the convenient use of the mobile body 3 after the posture is changed; the rod assembly can adjust the box body to a more stable posture, and the operator can pull the chassis in a more comfortable way.
[0109] In addition, by setting the first switch mechanism 21, the control of the movement of the first rod unit 1 relative to the first rod unit 1 is realized, so that the 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 rod unit according to the weight of the chassis or box, or choose to further start the second rod unit. The structure of the 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.
