Description

Technical Field

[0001] This utility model relates to the field of campervan folding technology, specifically to a foldable campervan. Background Technology

[0002] To enhance portability, existing foldable campervans often sacrifice structural strength. Their load-bearing frames generally use exposed, simple tubing or articulated designs. These structures have limited load-bearing capacity, and after repeated folding and use, gaps can easily form at the articulation points, causing the vehicle to wobble and become less stable, making it unsuitable for carrying a large amount of camping equipment.

[0003] More importantly, common folding solutions typically design the load-bearing components and folding mechanisms separately. The load-bearing components are often fixed or simply detachable and cannot be folded. This not only compromises the overall integrity of the product during storage but also exposes the main load-bearing components to the outside during handling or transportation, making them highly susceptible to damage from bumps and knocks, thus directly affecting the product's safety and lifespan. Utility Model Content

[0004] In view of this, the present invention provides a foldable camping vehicle to solve the problems of poor stability, easy damage and inconvenient storage caused by insufficient structural strength, easy loosening of hinge points and separation of load-bearing components from the folding mechanism in existing foldable camping vehicles.

[0005] This utility model provides a foldable camping vehicle, comprising:

[0006] Frame;

[0007] A load-bearing storage component, the length of which is parallel to the height direction of the frame, is disposed on the main body of the frame.

[0008] A load-bearing component, wherein the load-bearing component is slidably housed within a load-bearing storage component, and the load-bearing component has a working state in which it slides out of the load-bearing storage component and a protective state in which it is housed within the load-bearing storage component.

[0009] When the load-bearing component is in working condition, its first end is detachably connected to the vehicle frame, and its second end is detachably connected to the load-bearing storage component, so that the load-bearing component, the vehicle frame, and the load-bearing storage component together form a load-bearing structure.

[0010] Optionally, the second end of the load-bearing component is connected to the load-bearing storage component via a sliding rotation mechanism, so that the second end of the load-bearing component can rotate to a limited extent relative to the load-bearing storage component during sliding and when in working state, so as to achieve the connection between the first end and the frame.

[0011] Optionally, the sliding rotation mechanism includes a slider disposed at the second end and a slide rail disposed on the inner wall of the load-bearing storage component. The slider is slidably disposed in the slide rail, and a hinge shaft is also provided on the slider. When the load-bearing component slides out of the load-bearing storage component, the load-bearing component is rotatably connected to the load-bearing storage component through the hinge shaft.

[0012] Optionally, it also includes a locking structure, the locking structure including complementary locking members disposed at corresponding positions on the first end of the load-bearing member and the frame, the locking structure being adapted to lock the first end of the load-bearing member onto the frame when the load-bearing member is in the working state.

[0013] Optionally, there are two load-bearing components, and two load-bearing storage components are correspondingly provided, with the load-bearing storage components located in the middle region of the vehicle frame along its length.

[0014] Optionally, the frame includes:

[0015] A first support member and a second support member are arranged opposite to each other, and the load-bearing storage member is disposed between the first support member and the second support member. When the load-bearing member is in working condition, the first end of one load-bearing member is connected to the first support member, and the first end of the other load-bearing member is connected to the second support member.

[0016] Optionally, it also includes:

[0017] A vehicle body folding bracket is disposed inside the vehicle frame, and its two ends are respectively hinged to the first support member and the second support member. The vehicle body folding bracket is adapted to retract and fold along the length direction of the vehicle frame when the first support member and the second support member converge towards each other.

[0018] Optionally, it also includes:

[0019] A folding bracket for the vehicle bottom is provided at the bottom of the vehicle frame along the length of the vehicle frame. When the folding bracket is driven upward by an external force, it drives the first support member and the second support member to converge towards each other through a linkage mechanism, thereby realizing the folding of the vehicle frame.

[0020] Optionally, the frame is provided with a push-pull member, which is located on the side or top of the frame and is adapted to be externally driven to push and pull the frame.

[0021] Optionally, the push-pull member is rotatably connected to the frame. The push-pull member includes a first rod and a second rod that are rotatably connected.

[0022] Beneficial effects

[0023] The foldable camping vehicle provided by this utility model includes a frame; a load-bearing storage component, the length of which is parallel to the height direction of the frame and disposed on the frame body; and a load-bearing member, which is slidably stored within the load-bearing storage component, having a working state of sliding out of the load-bearing storage component and a protective state of being stored within the load-bearing storage component; when the load-bearing member is in the working state, a first end of the load-bearing member is detachably connected to the frame, and a second end is detachably connected to the load-bearing storage component, so that the load-bearing member, the frame, and the load-bearing storage component together form a load-bearing structure.

[0024] The foldable camping vehicle provided by this utility model features a first end detachably connected to the frame and a second end detachably connected to the load-bearing storage component when the load-bearing component is in operation. These three components together form a complete load-bearing structure, significantly improving the overall load-bearing capacity compared to existing exposed simple tubing or hinged frames. Furthermore, the multi-component connection reduces the reliance on a single hinge point for stress, preventing gaps from forming at the hinge points after repeated folding. This solves the problems of vehicle swaying and decreased stability, meeting the need to carry a large amount of camping equipment. The load-bearing component is designed to be sliding. The structure allows the load-bearing components to be stored within the load-bearing storage unit when the campervan is not in use or needs to be moved or transported. This effectively encloses the main load-bearing components, preventing them from being directly exposed to the outside and damaged by bumps, thus ensuring product safety and extending its service life. The sliding storage design of the load-bearing components and the load-bearing storage unit allows the load-bearing components to form an integrated storage structure with the frame, making the campervan easier to organize, reducing scattered parts, improving storage convenience, and better meeting the needs of portable use.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] The following is combined Figures 1 to 2 The following describes embodiments of the present invention.

[0032] According to an embodiment of the present invention, a foldable camping vehicle is provided, comprising:

[0033] Frame 1;

[0034] The load-bearing storage component 2 is installed on the main body of the frame 1 with its length direction parallel to the height direction of the frame 1.

[0035] The load-bearing component 3 is slidably stored in the load-bearing storage component 2. The load-bearing component 3 has a working state of sliding out of the load-bearing storage component 2 and a protective state of being stored in the load-bearing storage component 2.

[0036] When the load-bearing component 3 is in working condition, the first end of the load-bearing component 3 is detachably connected to the frame 1, and the second end is detachably connected to the load-bearing storage component 2, so that the load-bearing component 3, the frame 1 and the load-bearing storage component 2 together form a load-bearing structure.

[0037] The foldable camping vehicle provided by this utility model, when the load-bearing component 3 is in working condition, has its first end detachably connected to the frame 1 and its second end detachably connected to the load-bearing storage component 2, so that the three together form a complete load-bearing structure. Compared with existing exposed simple pipes or hinged frames, this improves the overall load-bearing capacity. At the same time, by connecting multiple components, it reduces the force dependence on a single hinge point and avoids gaps at the hinge points after repeated folding, thereby solving the problems of vehicle shaking and decreased stability, and meeting the needs of carrying a large amount of camping equipment. The load-bearing component 3 is designed to be slidable and foldable. The structure housed within the load-bearing storage component 2 allows the load-bearing component 3 to be stored within it when the campervan is not in use or needs to be moved or transported. This effectively encloses the main load-bearing component 3, preventing it from being directly exposed to the outside and damaged by bumps, thus ensuring product safety and extending its service life. The sliding storage design of the load-bearing component 3 and the load-bearing storage component 2 allows the load-bearing components to form an integrated storage structure with the frame 1, making the campervan easier to organize during storage, reducing scattered parts, improving storage convenience, and better meeting the needs of portable use.

[0038] Furthermore, the second end of the load-bearing component 3 is connected to the load-bearing storage component 2 through a sliding rotation mechanism, so that the second end of the load-bearing component 3 can rotate to a limited extent relative to the load-bearing storage component 2 during the sliding process and when it is in the working state, so as to achieve the connection between the first end and the frame 1.

[0039] In a straightforward manner, the second end of the load-bearing component 3 is connected to the load-bearing storage component 2 via a sliding rotation mechanism, further enhancing the practicality and ease of operation of the device. When the load-bearing component 3 needs to be switched from the protective state to the working state, the sliding rotation mechanism allows the second end of the load-bearing component 3 to rotate synchronously and to a limited extent while sliding along the load-bearing storage component 2. This eliminates the need for additional disassembly or adjustment of the connection structure, allowing for flexible adaptation to the connection position between the first end of the load-bearing component 3 and the frame 1. This effectively avoids the connection alignment difficulties caused by the fixed position of the load-bearing component 3. At the same time, when the load-bearing component 3 is in the working state, the mechanism can still finely adjust the force angle of the load-bearing component 3 through limited rotation, making the connection between the load-bearing component 3, the frame 1, and the load-bearing storage component 2 more closely match the actual force requirements. This ensures the stability of the load-bearing structure and reduces the risk of excessive local force due to connection position deviations, making the entire operation process smoother and the structure more adaptable.

[0040] Furthermore, the sliding rotation mechanism includes a slider disposed at the second end and a slide rail disposed on the inner wall of the load-bearing storage component 2. The slider is slidably disposed in the slide rail, and a hinge shaft is also disposed on the slider. When the load-bearing component 3 slides out of the load-bearing storage component 2, the load-bearing component 3 is rotatably connected to the load-bearing storage component 2 through the hinge shaft.

[0041] In simple terms, the sliding rotation mechanism, consisting of a slider, a slide rail, and a hinge shaft, ensures both functional implementation and structural reliability and ease of operation. The cooperation between the slide rail and the slider provides stable guidance for the sliding of the load-bearing component 3, preventing deviation or jamming during the sliding process and ensuring smooth sliding and retraction of the load-bearing component 3. The hinge shaft on the slider precisely fulfills the limited rotation requirements of the second end of the load-bearing component 3. Moreover, this structure is simple in components and has a solid connection, making it less prone to wear or gaps due to repeated folding and use. Compared to complex transmission structures, it is easier to maintain. At the same time, the cooperation between the slide rail and the slider can also help distribute the force when the load-bearing component 3 is working, further improving the overall stability of the load-bearing structure and reducing the stress on individual components.

[0042] In an alternative embodiment, the slider and slide rail can be replaced with a pulley and a slide groove. A pulley is provided at the second end of the load-bearing member 3, and a matching slide groove is opened on the inner wall of the load-bearing storage member 2. The pulley slides along the slide groove to realize the movement of the load-bearing member 3. At the same time, a rotatable connection structure is provided between the pulley shaft and the load-bearing member 3 to replace the hinge shaft, which can also meet the dual requirements of sliding and rotation.

[0043] Furthermore, it also includes a locking structure, which includes complementary locking members disposed at the corresponding positions of the first end of the load-bearing member 3 and the frame 1. The locking structure is adapted to lock the first end of the load-bearing member 3 onto the frame 1 when the load-bearing member 3 is in the working state.

[0044] As easily understood, the complementary locking element, located at the first end of the load-bearing component 3 corresponding to the position of the frame 1, provides reliable fixation for the load-bearing component 3 in operation. Through the locking action of the complementary locking element, the load-bearing component 3 can be prevented from shifting or loosening due to vibration, external impact, etc. when carrying camping equipment, ensuring that the load-bearing structure composed of the load-bearing component 3, the frame 1, and the load-bearing storage component 2 always remains stable, further improving the overall load-bearing safety of the vehicle. On the other hand, the design of the complementary locking element makes the locking and unlocking operation of the load-bearing component 3 simpler. Without the need for complicated tools, users can quickly complete the fixing and storage switching of the load-bearing component 3, taking into account both structural reliability and ease of use, and effectively solving the problem of easy loosening of existing campervan load-bearing component connections.

[0045] Specifically, in this embodiment, the complementary locking component can adopt a structure of elastic buckle and slot. An elastic buckle with a return spring is provided at the first end of the load-bearing component 3, and a slot adapted to the shape of the buckle is opened at the corresponding position of the frame 1. When the load-bearing component 3 slides out to the working position, the elastic buckle automatically engages with the slot under the action of the spring to achieve locking. To unlock, simply press the buckle to disengage it from the slot.

[0046] In an optional embodiment, a threaded knob and a threaded hole are used as complementary locking components. A threaded knob with a handle is provided at the first end of the load-bearing component 3, and an internal threaded hole is opened at the corresponding position of the frame 1. When the load-bearing component 3 is aligned, the threaded knob is rotated to screw into the threaded hole, and locking is achieved through thread engagement. This method has higher locking strength and is suitable for scenarios that carry heavier equipment.

[0047] Furthermore, there are two load-bearing components 3, and two load-bearing storage components 2 are provided accordingly, with the load-bearing storage components 2 located in the middle area of ​​the frame 1 along its length.

[0048] In a straightforward manner, setting both the load-bearing component 3 and the load-bearing storage component 2 as two units, with the load-bearing storage component 2 located in the middle of the frame 1 along its length, optimizes the overall performance of the campervan. The two load-bearing components 3 can symmetrically distribute the load-bearing pressure on the frame 1, avoiding localized structural damage caused by concentrated stress on a single load-bearing component 3, thus increasing the overall load-bearing capacity and durability of the vehicle, making it more suitable for camping scenarios with multiple pieces of equipment. At the same time, the central location allows the load-bearing structure formed by the two load-bearing components 3 to evenly cover the stress points along the length of the frame 1, reducing deformation of the frame 1 caused by uneven stress, further enhancing the stability of the vehicle. Moreover, the storage layout in the middle does not occupy the usable space at both ends of the frame 1, balancing the load-bearing function with the space utilization of the campervan, and preventing improper placement of the storage component from affecting equipment placement or personnel activities.

[0049] Specifically, in this embodiment, the load-bearing component 3 and the load-bearing storage component 2 are configured as two sets, each set including two load-bearing components 3 and two load-bearing storage components 2, and the two sets are respectively set on both sides of the width direction of the frame 1, which further optimizes the load-bearing performance and structural stability of the whole vehicle. From the perspective of force distribution, the two sets of symmetrical load-bearing structures on both sides can evenly distribute the weight of the camping equipment to both ends of the width direction of the frame 1, avoiding the risk of the frame 1 tilting or tipping over due to the concentration of force on one side. Especially when carrying irregularly shaped equipment (such as large tents, folding tables and chairs), the load-bearing components 3 on both sides can support the two sides of the equipment respectively, improving the placement stability. It should be noted that in this embodiment, the two sets of load-bearing components 3 and load-bearing storage components 2 are set on the two sides of the width direction of the frame 1. In other embodiments, the frame 1 can also be divided to set more sets of load-bearing components 3 and load-bearing storage components 2, or only a single set of load-bearing components 3 and load-bearing storage components 2 can be set and located at the midpoint of the width direction of the frame 1.

[0050] In one optional embodiment, the load-bearing component 3 and the load-bearing storage component 2 can be configured as a single set. To ensure the folding effect of the entire vehicle, the load-bearing component 3 can be configured as a telescopic tube, and the load-bearing storage component 2 can be set on one side of the frame 1. After pulling out the main body of the load-bearing component 3, it can be telescopically extended and then overlapped on the other side of the frame to achieve support. Of course, in other embodiments, the length of the frame can be divided (e.g., into three equal parts) according to the actual load-bearing requirements of the campervan, and multiple sets of load-bearing components 3 and load-bearing storage components 2 can be set to achieve better load-bearing capacity.

[0051] Furthermore, the frame 1 includes:

[0052] The first support member 11 and the second support member 12 are arranged opposite to each other, and the load-bearing storage member 2 is arranged between the first support member 11 and the second support member 12. When the load-bearing member 3 is in working state, the first end of one load-bearing member 3 is connected to the first support member 11, and the first end of the other load-bearing member 3 is connected to the second support member 12.

[0053] Specifically, in this embodiment, both the first support member 11 and the second support member 12 are U-shaped tubes, arranged parallel to each other with the same opening orientation. The two straight sections of the U-shaped tube are perpendicular to the ground, forming a stable frame foundation. At the same time, the two load-bearing storage members 2 are respectively vertically fixed between the opposite straight sections of the first support member 11 and the second support member 12, and the height of the load-bearing storage member 2 is adapted to the height of the straight section of the U-shaped tube, ensuring that the load-bearing member 3 can be connected to the straight section of the second support member 12 after sliding out. In an alternative embodiment, the U-shaped tube can be replaced with a U-shaped structure formed by bending a square tube. The larger contact area of ​​the square tube when connecting with other components can be used to improve the stability of the fixation. Alternatively, a U-shaped tube with reinforcing ribs can be used, with longitudinal reinforcing ribs welded to the inside of the tube to enhance the resistance to deformation. The diameter of the U-shaped tube can also be adjusted according to the load-bearing requirements of the campervan. For scenarios with higher load-bearing requirements, a larger diameter U-shaped tube can be selected, while for scenarios with higher lightweight requirements, a thin-walled U-shaped tube can be selected, while maintaining the overall U-shaped structure's compatibility with the frame 1.

[0054] Furthermore, it also includes:

[0055] The vehicle body folding bracket 13 is disposed inside the vehicle frame 1, and its two ends are respectively hinged to the first support member 11 and the second support member 12. The vehicle body folding bracket 13 is adapted to retract and fold along the length direction of the vehicle frame 1 when the first support member 11 and the second support member 12 converge towards each other.

[0056] In a straightforward manner, the design of the folding bracket 13, with its two ends hinged to the first support member 11 and the second support member 12 respectively, provides lateral support to the frame 1 when the campervan is unfolded, enhancing the connection strength between the first support member 11 and the second support member 12 and preventing them from shifting outward or deforming due to the weight, thus improving the overall rigidity of the frame 1. Furthermore, when the campervan needs to be stored, it retracts and folds synchronously along the length of the frame 1 as the first support member 11 and the second support member 12 converge, eliminating the need for additional disassembly of the bracket structure and simplifying the folding process. This retraction and folding method also significantly reduces the length of the frame 1, minimizing storage space and making the campervan easier to move and store. In addition, the folding bracket guides the movement of the first and second support members 12 during folding, preventing misalignment or jamming when the two support members converge, ensuring smooth folding and further enhancing the user experience.

[0057] Specifically, in this embodiment, there are two vehicle body folding brackets 13, arranged parallel to each other along the width direction of the frame 1. The two parallel folding brackets can form evenly distributed lateral support points in the width direction of the frame 1. Compared with a single bracket, this can more evenly distribute the lateral stress borne by the first support member 11 and the second support member 12, avoiding bending deformation in the middle of the frame 1 due to insufficient local support. Especially when carrying heavy equipment, it can significantly improve the overall deformation resistance of the frame 1. Of course, in other embodiments, one, three or more vehicle body folding brackets 13 can be provided according to the weight of the load.

[0058] Specifically, in this embodiment, the vehicle body folding bracket 13 is an X-shaped folding bracket. Compared with the ordinary straight rod folding bracket, the X-shaped structure forms a triangular stable support through cross hinges, which can disperse stress in both the lateral and longitudinal directions, further improving the deformation resistance of the frame 1. Especially when the load is uneven, it can effectively prevent the frame 1 from tilting on one side. Moreover, the X-shaped structure has a larger shrinkage range when folded, which can further reduce the length dimension of the frame 1 and reduce the storage space occupied.

[0059] In practice, two X-shaped folding brackets are arranged parallel to each other along the width of the frame 1. The four ends of each X-shaped bracket are connected to the inner tube walls of the first support member 11 and the second support member 12 through hinges. The hinge point is located at the middle of the height direction of the frame 1, ensuring that the bracket can evenly bear the force of the two support members when unfolded. When folded, it can converge and cross-contract synchronously with the two support members. Wear-resistant pads are set at the hinge to reduce wear caused by repeated folding.

[0060] Furthermore, it also includes:

[0061] The vehicle bottom folding bracket 14 is set at the bottom of the vehicle frame 1 along the length direction of the vehicle frame 1. When the vehicle bottom folding bracket 14 is driven upward by an external force, it drives the first support member 11 and the second support member 12 to converge towards each other through the linkage mechanism, thereby realizing the folding of the vehicle frame 1.

[0062] In a straightforward manner, the layout of the underbody folding bracket 14, installed along the length of the vehicle frame 1 at the bottom, avoids occupying the internal or external space of the vehicle frame 1, thus preventing interference with the placement of camping equipment and personnel activities. It also allows users to fold the vehicle more easily by applying force from the bottom; simply applying an upward force to the underbody folding bracket 14 will cause the two support members to converge towards each other via a linkage mechanism, achieving the overall folding of the vehicle frame 1. This simplifies the operation and is particularly suitable for single-person operation. Simultaneously, the bracket's folding mechanism ensures that the convergence speed and displacement of the two support members are consistent, preventing misalignment or jamming of components due to uneven force application during manual operation and protecting the connecting structure of the vehicle frame 1 from damage. Furthermore, when the vehicle frame 1 is unfolded, the underbody folding bracket 14 also serves as a bottom reinforcement structure, enhancing the overall torsional resistance of the vehicle frame 1 and reducing bottom deformation caused by ground bumps during campervan movement, thus balancing folding functionality and structural support.

[0063] Specifically, in this embodiment, the undercarriage folding bracket 14 is an H-shaped folding bracket. Specifically, it uses two parallel transverse rods and one longitudinal connecting rod to form an H-shaped frame. Each transverse rod is divided into two segments, and the connection points of the two transverse segments and the corresponding positions of the longitudinal connecting rod are hinged via hinge shafts, forming a composite hinge structure of transverse segmented hinges and longitudinal connections. When the longitudinal connecting rod is lifted and folded upwards by external force, the two transverse segments will rotate synchronously around the longitudinal connecting rod under the traction of the hinge shaft. The transverse rods, originally in a horizontally extended state, gradually move closer to the longitudinal connecting rod, and the angle between the segments gradually decreases, achieving the folding and retraction of the transverse rods.

[0064] The linkage structure specifically includes: a linkage joint is fixed at the end of each transverse bar away from the longitudinal connecting bar. The linkage joint is hinged to the connecting lugs at the bottom of the first support member 11 and the second support member 12 via a pin. At the same time, a guide slider is provided between the longitudinal connecting bar and the fixed seat at the bottom of the frame 1. The guide slider can slide along the vertical groove on the fixed seat. When the longitudinal connecting bar is lifted upward, on the one hand, the rotation at the hinge point of the transverse bar segment drives the transverse bar to retract. On the other hand, the linkage joint pulls the first support member 11 and the second support member 12 to rotate towards each other around the bottom hinge point and converge. The guide slider slides along the vertical groove to provide stable guidance for the lifting of the longitudinal connecting bar and prevent it from deviating and jamming. Finally, through the synchronous action of the folding of the transverse bar and the convergence of the support members, the frame 1 is smoothly retracted along the length direction. Moreover, the entire linkage process does not require the operation of other parts. It can be completed by simply lifting the longitudinal connecting bar, which further improves the convenience of folding.

[0065] Furthermore, a push-pull component 4 is provided on the frame 1. The push-pull component 4 is located on the side or top of the frame 1 and is adapted to be externally driven to push and pull the frame 1.

[0066] Intuitively, the design of the push-pull component 4 allows users to apply force without bending over or leaning to the bottom of the frame 1. Whether pushing the campervan to move on a flat road or adjusting the parking angle in a campsite, users can apply force in a more comfortable posture, avoiding lower back fatigue caused by improper operating posture. It is especially suitable for scenarios where a large amount of equipment is being carried while pushing the frame 1.

[0067] It should be noted that in this embodiment, the push-pull component 4 is detachably mounted on the frame 1, for example, by means of a snap-fit ​​connection. Of course, in an optional embodiment, the push-pull component 4 may also be fixedly mounted on the frame 1.

[0068] Furthermore, the push-pull member 4 is rotatably connected to the frame 1. The push-pull member 4 includes a first rod and a second rod that are rotatably connected. The push-pull member 4 has an unfolded straight state and a folded state that is bent at the rotatable connection. The frame 1 is also provided with a locking part, which is suitable for locking the push-pull member 4 in the straight state or the folded state.

[0069] In an easy-to-understand way, the push-pull component 4 is designed as a rotatable structure connected to the frame 1 and composed of a first rod and a second rod. It is also equipped with a locking part, which further enhances the practicality and adaptability of the push-pull component 4. When not in use, the push-pull component 4 can rotate around the frame 1 and bend to a folded state at the rod connection, which greatly reduces the space occupied and prevents the protruding push-pull component 4 from being bumped and damaged during storage or transportation. It will also not hinder the loading and unloading of camping equipment. When in use, the push-pull component 4 can be fixed in a straight line by the locking part to ensure structural stability when force is applied.

[0070] Specifically, the locking part adopts a structure of elastic buckle and positioning hole. An elastic buckle with spring is set at the rotational connection between the first rod and the second rod. Positioning holes are opened at the corresponding straight and folded positions of the two rods. When the push-pull part 4 is adjusted to the target state, the elastic buckle is engaged into the corresponding positioning hole under the action of the spring to achieve locking. To unlock, press the buckle to disengage from the positioning hole.

[0071] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
