Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle equipment technology, and in particular to an extension platform and vehicle. Background Technology
[0002] To increase the available space for passengers or cargo, pickup trucks, as well as some RVs (such as trailer RVs) and vans, are equipped with a rear platform. However, existing rear platforms are generally fixed structures, and their size is limited by the vehicle's external dimensions, so they are often small in area. For example, the rear platform area of a pickup truck cannot exceed the size of the pickup truck's cargo box, while the rear platform of an RV can only be confined to the interior of the RV, resulting in limited usable space and a poor user experience. Therefore, there is a need to develop a rear platform with more usable space. Utility Model Content
[0003] The purpose of this invention is to overcome the technical problem that the mobile platform mounted on a vehicle in the prior art adopts a fixed structure, which results in its usable space being limited by the external dimensions of the vehicle, and to provide an expansion platform and vehicle.
[0004] In a first aspect, this utility model provides an extension platform, comprising:
[0005] A first platform is connected to a first hinge on one side along a first direction. The axis of the first hinge is set along a second direction. The first direction, the second direction, and the normal of the first platform are perpendicular to each other.
[0006] The second platform is connected to the first platform via the first hinge, and the normal of the second platform is perpendicular to the second direction.
[0007] Side railings are provided on both sides of the second platform along the second direction; the side railings are connected to the second platform through a second hinge, and the axis of the second hinge is perpendicular to the second direction and the normal of the second platform.
[0008] Extended guardrails are provided on both sides of the side guardrail along the first direction; the extended guardrails are connected to the side guardrails by a third hinge, the axis of the third hinge being perpendicular to the axis of the second hinge.
[0009] The extended platform of this solution has an unfolded state and a folded state. To enter the unfolded state, the second platform can be swung to the side of the first platform along the first direction via the first hinge, and the second platform is coplanar with the first platform. This allows the second platform and the first platform to be combined into a larger movable platform, and the movable area of the movable platform matches the sum of the areas of the first platform and the second platform. The usable space is also increased accordingly, which can facilitate the free movement of passengers or the placement of goods, such as as a fishing platform or a balcony.
[0010] To enter the folded state, the second platform can be swung relative to the first platform via the first hinge, so that the second platform is swung to one side of the first platform along its normal direction. This allows the projections of the second platform and the first platform on the plane perpendicular to the normal direction of the first platform to overlap, thereby significantly reducing the footprint of this solution, avoiding obstruction of vehicle passage, and also reducing the difficulty of storage and transportation.
[0011] The expansion platform of this solution is also connected to a side guardrail and an extension guardrail on the second platform. When it is to be deployed, the side guardrail can be swung relative to the second platform to be perpendicular to the second platform via the second hinge, and then the extension guardrails on both sides of the side guardrail can be swung separately via the corresponding third hinge. The extension guardrail closer to the first platform swings to be flush with the side of the first platform along the second direction, and the extension guardrail farther from the first platform swings to be flush with the side of the second platform away from the first platform. Thus, the side guardrail and the extension guardrail respectively form a complete protection on both sides of the second platform along the second direction, both sides of the first platform along the second direction, and the side of the second platform away from the first platform, preventing people or goods from falling off the movable platform (the side of the first platform away from the second platform is used to connect with the vehicle body, so no protection is required).
[0012] When entering the folding state, the operation can be reversed. For example, first, the third hinge allows the extended guardrails on both sides of the side guardrail to swing to the sides of the side guardrail along its normal direction, so that the extended guardrails overlap with the side guardrails. Then, the second hinge allows the side guardrails, along with the extended guardrails, to swing to one side of the second platform along its normal direction, so that the extended guardrails, side guardrails, and second platform overlap. Subsequently, the first hinge allows the second platform, along with the extended guardrails and side guardrails, to swing to one side of the first platform along its normal direction, so that the projections of the extended guardrails, side guardrails, second platform, and first platform on the plane perpendicular to the normal direction of the first platform all overlap. This avoids the side guardrails and extended guardrails obstructing the folding of the scheme, or extending from the first / second platform, which would increase the footprint of the scheme in the folding state.
[0013] Preferably, the first platform has a storage slot on one side along its normal direction, and the second platform can swing relative to the first platform to disengage from or fit into the storage slot; and / or, the second platform has a storage slot on the side facing away from the side railing.
[0014] When folded, the side of the second platform facing away from the side railing will abut against the side of the first platform along its normal direction; therefore, this design provides storage slots on the corresponding surfaces of the first and / or second platforms, wherein:
[0015] When the storage slot is set on the first platform, the second platform can be fitted into the storage slot of the first platform when folded. On the one hand, the side wall of the storage slot can limit the second platform and prevent structural damage caused by the second platform shaking relative to the first platform. On the other hand, it can also reduce the total thickness of this solution along the normal direction of the first platform in the folded state, thereby further reducing the obstruction of this solution to vehicle passage and the difficulty of storage and transportation of this solution.
[0016] When a storage slot is set on the second platform, when the second platform is in the folded state, the side of the second platform away from the side railing will abut against the first platform, thereby closing the storage slot. Therefore, the storage slot can be used to hold objects without worrying about objects falling out.
[0017] Preferably, the second hinges corresponding to the two side rails are staggered along the normal direction of the second platform.
[0018] Since side railings are provided on both sides of the second plane, if the second hinges of the side railings on both sides coincide along the normal direction of the second platform, the sum of the lengths of the side railings on both sides must be less than or equal to the length of the second platform along the second direction; otherwise, the side railings on both sides will interfere with each other when swinging. Therefore, this solution chooses to offset the positions of the second hinges on both sides along the normal direction of the second platform. When this solution is in the folded state, the positions of the side railings on both sides along the normal direction of the second platform will also be offset from each other, which can greatly reduce the interference between the side railings on both sides and help increase the length of the side railings to ensure their protective effect.
[0019] Preferably, the edge of the second platform is also connected to a stop structure; the height of the end of the stop structure away from the second platform along the normal direction of the second platform is higher than the height of the end of the side guardrail near the second platform, and / or, the height of the end of the stop structure away from the second platform along the normal direction of the second platform is higher than the height of the end of the extension guardrail near the second platform.
[0020] Because the height of the stop structure exceeds the height of the bottom of the side guardrail and / or extension guardrail, when the side guardrail and / or extension guardrail swing to the stop structure, the stop structure can prevent further swinging of the side guardrail and / or extension guardrail, thereby limiting the positional relationship between the side guardrail and / or extension guardrail and the second platform. On the one hand, this allows the side guardrail and / or extension guardrail to be more securely confined to the second platform, thereby improving the protective performance of the side guardrail and / or extension guardrail. On the other hand, it can also alert the operator during the deployment of this solution that the side guardrail and / or extension guardrail has swung to the predetermined position, passively preventing the side guardrail and / or extension guardrail from swinging beyond the limit, thereby improving the efficiency and accuracy of the deployment operation.
[0021] Preferably, the stop structure can be detachably connected to the side guardrail, and / or the stop structure can be detachably connected to the extension guardrail.
[0022] This solution can further improve the limiting effect between the side railings and / or extension railings and the second platform, thereby improving the protective performance of the side railings and / or extension railings.
[0023] Preferably, at least one side rail is connected to a guardrail gate, and / or at least one extension rail is connected to a guardrail gate; the guardrail gate is openable and closable.
[0024] This solution facilitates the entry and exit of personnel or goods from the activity platform.
[0025] Preferably, the side of the first platform away from the side railing is also connected to a support leg, and / or the side of the second platform away from the side railing is also connected to a support leg.
[0026] This solution provides additional support between the first and / or second platform and the ground, thereby improving the stability of the mobile platform.
[0027] Preferably, the length of the support leg is adjustable.
[0028] This solution can adapt to different vehicle models or uneven ground by adjusting the length of the support legs.
[0029] In a second aspect, the present invention provides a vehicle, including a vehicle body, and also includes an extension platform of the present invention, wherein the end of the first platform opposite to the second platform is connected to the vehicle body.
[0030] The vehicle in this solution can increase its living space by deploying an extension platform, allowing passengers to move freely or to place cargo.
[0031] Preferably, a fifth hinge is provided between the first platform and the vehicle body, and the axis of the fifth hinge is parallel to the first hinge.
[0032] This design allows the expansion platform to swing relative to the vehicle body, thus fitting the vehicle body more closely and further reducing the space occupied by the design in the folded state.
[0033] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0034] 1. This utility model provides an extension platform, which connects a first platform and a second platform via a first hinge. The second platform is equipped with swingable side rails and extension rails, enabling switching between an unfolded and folded state. When the platform is in the unfolded state, its usable area matches the sum of the areas of the first and second platforms, expanding the available space and facilitating free movement of passengers or placement of goods. The rails also provide protection. When the platform is in the folded state, the first platform, second platform, side rails, and extension rails overlap, reducing the platform's footprint and preventing obstruction of vehicle passage. This also reduces the difficulty of storage and transportation.
[0035] 2. This utility model provides a vehicle equipped with an extension platform on the vehicle body. When passengers need to move freely or place goods, the extension platform can be unfolded to increase the available space; when the vehicle needs to be driven, the extension platform can be folded to reduce the space it occupies, thereby avoiding the extension platform from obstructing the passage of the vehicle.

[0059] Example 1
[0060] like Figures 1 to 14As shown, an extension platform includes a first platform 1, a second platform 2, side rails 3, and extension rails 4. The first platform 1 is connected to a vehicle body 8 on one side along a first direction, and a first hinge 101 is connected to the other side. The axis of the first hinge 101 is set along a second direction, and the first direction, the second direction, and the normal of the first platform 1 are mutually perpendicular. The second platform 2 is connected to the first platform 1 via the first hinge 101, and the normal of the second platform 2 is perpendicular to the second direction. Side rails 3 are provided on both sides of the second platform 2 along the second direction, and the side rails 3 are connected to the second platform 2 via second hinges 102. The axis of the second hinges 102 is perpendicular to the second direction and the normal of the second platform 2. Extension rails 4 are provided on both sides of the side rails 3 along the first direction. The extension rails 4 are connected to the side rails 3 via third hinges 103, and the axis of the third hinge 103 is perpendicular to the axis of the second hinge 102 and the normal of the side rails 3.
[0061] exist Figures 1 to 13 The diagram also uses a Cartesian coordinate system to label the various directions. Arrow X points to the first direction; arrow Y points to the second direction, which is the normal to the side railing 3 in its unfolded state; and arrow Z points to the normal to the first platform 1, which is also the normal to the second platform 2 in both its unfolded and folded states, and the normal to the side railing 3 in its folded state. It is important to note that... Figure 1 The planar unfolded diagram is merely a schematic diagram ignoring the hinge rotation angle limitations, intended to more clearly illustrate the positions and connections of the first platform 1, the second platform 2, the side railing 3, and the extended railing 4. It is not intended to limit the ability of the first platform 1, the second platform 2, the side railing 3, and the extended railing 4 to swing to a certain angle. Figure 1 The state shown.
[0062] In the above embodiment, the first platform 1 has a storage groove 11 on one side along its normal direction, and the second platform 2 can swing relative to the first platform 1 to disengage from or engage with the storage groove 11. For example Figure 3 As shown in the figure, a partial cross-section of the first platform 1 is shown, revealing that a storage groove 11 for accommodating the second platform 2 is provided on its lower surface; and the storage groove 11 can either completely accommodate the second platform 2 or only accommodate a part of the second platform 2.
[0063] In the above embodiment, the second hinges 102 corresponding to the side rails 3 are staggered along the normal direction of the second platform 2. For example... Figure 11 As shown, the second hinges 102 on both sides of the second platform 2 are at different heights along the direction indicated by arrow Z, so that when the side railings 3 on both sides are in the folded state, they can also be adjusted as shown in the image. Figure 4The side rails are staggered in the direction indicated by arrow Z so that the length of the side rails 3 (its length in the second direction when folded) can be close to or even equal to the length of the second platform 2 in the second direction.
[0064] In an optional embodiment, a stop structure 21 is also connected to the edge of the second platform 2; the height of the end of the stop structure 21 away from the second platform 2 along the normal direction of the second platform 2 is higher than the height of the end of the side railing 3 near the second platform 2, and / or, the height of the end of the stop structure 21 away from the second platform 2 along the normal direction of the second platform 2 is higher than the height of the end of the extended railing 4 near the second platform 2. Taking the case where it is necessary to block the extended railing 4 away from the first platform 1 as an example, such as... Figures 5 to 7 As shown, two baffles are connected to the side of the second platform 2 away from the first platform 1 as stop structures 21, and the upper end of the stop structure 21 extends upward beyond the lower end of the extension guardrail 4, so as to block and limit the extension guardrail 4 when it is about to swing beyond the edge of the second platform 2; if it is to block the extension guardrail 4 close to the first platform 1, or to block the side guardrail 3, the stop structure 21 can be set at the corresponding position, and the upper end of the stop structure 21 can be higher than the lower end of the corresponding extension guardrail 4 or side guardrail 3 (for example, the stop structure 21 is set on the edges of the second platform 2 along the second direction).
[0065] In an optional embodiment, the side of the second platform 2 facing away from the side railing 3 is also provided with a storage slot 11. When the second platform 2 is in a folded state, the side of the second platform 2 facing away from the side railing 3 will abut against the first platform 1, thereby closing the storage slot 11. Therefore, the storage slot 11 can be used to hold objects, such as... Figure 3 As shown, the removed support leg 6 is accommodated in the storage slot 11 of the second platform 2.
[0066] In the above embodiments, the specific form of the stop structure 21 includes, but is not limited to, sheet-like, block-like, or column-like components, as long as they can be used to block the side guardrail 3 and / or the extension guardrail 4; and the arrangement of the stop structure 21 along the edge of the second platform 2 includes, but is not limited to, continuous arrangement or intermittent arrangement.
[0067] In the above embodiments, the stop structure 21 can be detachably connected to the side guardrail 3, and / or, the stop structure 21 can be detachably connected to the extension guardrail 4; taking the case where the stop structure 21 and the extension guardrail 4 need to be detachably connected as an example, such as Figure 9 As shown, the stop structure 21 is connected to the extension guardrail 4 via a threaded connector; in addition to threaded connectors, other detachable connection methods such as snap-fit connections, tenon and mortise connections, or pin connections can also be used.
[0068] In an optional embodiment, at least one side railing 3 is connected to a guardrail door 5, and / or at least one extended railing 4 is connected to a guardrail door 5; the guardrail door 5 is openable and closable. To connect a guardrail door 5 to a side railing 3, an opening can be made in the side railing 3, and then the guardrail door 5 can be connected to the opening; similarly, to connect a guardrail door 5 to an extended railing 4, an opening can be made in the extended railing 4, and then the guardrail door 5 can be connected to the opening; or an independent guardrail door 5 can be connected to one side of the extended railing 4; the opening and closing methods of the guardrail door 5 include, but are not limited to, sliding doors, revolving doors, or folding doors; for example... Figure 1 As shown, in this embodiment, an independent guardrail gate 5 is connected to one of the extended guardrails 4, which is away from the first platform 1 and opposite to the corresponding side guardrail 3. This guardrail gate 5 is connected to the extended guardrail 4 via a fourth hinge 104. The axis of the fourth hinge 104 is parallel to the axis of the third hinge 103, thus enabling... Figure 8 As shown, the fourth hinge 104 causes the guardrail gate 5 to swing relative to the extended guardrail 4, thereby realizing the opening and closing of the guardrail gate 5; and as... Figure 6 As shown, the guardrail gate 5 can also be folded or unfolded via the fourth hinge 104.
[0069] In optional embodiments, a support leg 6 is also connected to the side of the first platform 1 facing away from the side railing 3, and / or, a support leg 6 is also connected to the side of the second platform 2 facing away from the side railing 3. The connection method between the support leg 6 and the first platform 1 includes, but is not limited to, a detachable connection or a movable connection, to facilitate the removal or retraction of the support leg 6 during folding, avoiding obstruction of the folding action by the support leg 6. Specific forms of detachable connections include, but are not limited to, threaded connections, tenon and mortise connections, or snap-fit connections. Specific forms of movable connections include, but are not limited to, hinged connections or planar linkage mechanisms, as long as the support leg 6 can be moved to a position that does not obstruct the folding action of the side railing 3 and the extended railing 4. The connection method between the support leg 6 and the second platform 2 is similar. For example... Figures 10 to 11 As shown, two support legs 6 are inserted below the second platform 2.
[0070] In an optional embodiment, the length of the support leg 6 is adjustable. The length adjustment of the support leg 6 can be achieved, but is not limited to, using a threaded adjustment mechanism, a telescopic tube mechanism, or a sliding snap-fit mechanism; for example... Figure 11 As shown, a foot pad 61 is provided at the bottom of the support leg 6. The foot pad 61 is threadedly connected to the support leg 6. By rotating the foot pad 61, the foot pad 61 can be moved closer to or away from the support leg 6, thereby adjusting the overall length of the support leg 6.
[0071] In optional implementations, such as Figure 1 As shown, the side railing 3, the extension railing 4, and the railing gate 5 are all grid-like components, which can ensure the protective effect while reducing weight and material consumption.
[0072] like Figure 2 The diagram shown is a three-dimensional structural illustration of this embodiment in its folded state. To switch to the unfolded state, follow these steps:
[0073] A1, such as Figure 3 As shown, the second platform 2 is oscillating relative to the first platform 1 via the first hinge 101 until the second platform 2 is as shown. Figure 4 As shown, the platform swings to one side of the first platform 1 along the first direction, and the second platform 2 is coplanar with the first platform 1.
[0074] A2, such as Figure 5 As shown, the side railings 3 on both sides swing relative to the second platform 2 through the second hinge 102, and drive the corresponding extension railings 4 to stand upright relative to the second platform 2.
[0075] A3, such as Figure 6 As shown, the third hinge 103 causes each extended guardrail 4 to swing relative to the corresponding side guardrail 3 until... Figure 7 As shown, the extended guardrail 4 close to the first platform 1 is swung to above the first platform 1 and flush with the side of the first platform 1 along the second direction; the extended guardrail 4 away from the first platform 1 is swung to be flush with the side of the second platform 2 away from the first platform 1.
[0076] A4, such as Figure 9 and Figure 10 As shown, support legs 6 are installed below the second platform 2, and the extended guardrail 4 is connected to the corresponding stop structure 21 via threaded connectors to complete the deployment operation; when it is necessary to open or close the door, as... Figure 8 As shown, the guardrail gate 5 can be swung relative to the extended guardrail 4 by means of the fourth hinge 104.
[0077] To switch back from the unfolded state to the folded state, follow these steps:
[0078] B1. Remove the support leg 6 below the second platform 2 and disconnect the connection between the extension guardrail 4 and the corresponding stop structure 21.
[0079] B2. The third hinge 103 causes each extended guardrail 4 to swing relative to its corresponding side guardrail 3 until... Figure 5 As shown, the extended guardrails 4 on both sides of the side guardrail 3 are respectively attached to both sides of the side guardrail 3 along its normal direction.
[0080] B3. The second hinge 102 causes the side railings 3 on both sides to swing relative to the second platform 2, and drives the corresponding extension railings 4 to move together. Figure 4 The surface is laid flat and attached to the normal side of the second platform 2.
[0081] B4. The second platform 2 is oscillated relative to the first platform 1 by means of the first hinge 101 until the second platform 2 is as follows. Figure 2 As shown, the folding operation is completed when the second platform 2 is folded to one side of the first platform 1 along its normal direction and the second platform 2 is coplanar with the first platform 1.
[0082] Example 2
[0083] like Figures 12 to 14 As shown, a vehicle includes a body 8 and an extension platform according to embodiment 1. The end of the first platform 1 facing away from the second platform 2 is connected to the body 8. The specific type of the body 8 includes, but is not limited to, pickup trucks, RVs, or vans; the specific connection position of the first platform 1 depends on actual needs, including but not limited to the rear or side of the vehicle; for example... Figures 12 to 13 As shown, the first platform 1 is connected to the rear of the vehicle body 8.
[0084] In an optional embodiment, a fifth hinge may be further provided between the first platform 1 and the vehicle body 8. The axis of the fifth hinge is arranged along the second direction, so that when the extension platform is in the folded state, the extension platform as a whole can be swung relative to the vehicle body 8 through the fifth hinge until the extension platform as a whole is folded. Figure 12 The extension platform is designed to fit the rear of the vehicle body 8 to reduce the space occupied by the extension platform along the front-rear direction of the vehicle body 8.
[0085] In the above embodiments, when the vehicle body 8 has a tailgate and the tailgate can be opened and closed in a second direction, the tailgate of the vehicle body 8 can be directly used as the first platform 1.
[0086] In an optional embodiment, the extension guardrail 4 near the vehicle body 8 can be detachably connected to the vehicle body 8. This increases the load transfer path between the extension platform and the vehicle body 8, thus improving the load-bearing capacity of the extension platform. Furthermore, the vehicle body 8 can limit the extension guardrail 4, preventing it from swaying randomly without restriction. Specific methods of detachable connection include, but are not limited to, connecting chains 7, ropes, or pull rods, for example...
