Description

Technical Field

[0001] This application relates to the field of automotive structural technology, and more particularly to an extension component and an automobile. Background Technology

[0002] Currently, vehicles have become the third space for users. Travel scenarios are becoming increasingly diverse, and demands are also increasing. Different tools are available on the market to meet the needs of different usage scenarios, but they are generally independent of the vehicle's structure. On the one hand, storing them in the car will occupy the car's storage space, and on the other hand, they have no functional interaction with the vehicle, resulting in poor ease of use. Furthermore, they may not be able to meet emergency needs if forgotten. Utility Model Content

[0003] In view of this, embodiments of this application provide an expansion component and a vehicle, which are intended to integrate the expansion structure into the vehicle to meet the functional needs of users in certain scenarios.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows: In a first aspect, embodiments of this application provide an expansion component applied to an automobile, wherein the expansion component includes: A support structure, including a support platform and a lifting assembly, wherein the support platform is mounted to the trunk of the vehicle via the lifting assembly; and, An extension platform is installed on the support platform and is movable in the horizontal direction. In its movable stroke, it has at least a storage position placed on the support platform and an extension position that partially extends out of the support platform. The bottom of the extension platform is provided with adjustable support legs. In the storage position, the support legs extend horizontally to be stored in the extension platform. In the extension position, the support legs extend vertically to support the suspended end of the extension platform.

[0005] The extension component provided in this application is applied to automobiles, mainly used to integrate an extension platform into the vehicle, improving the problems of the extension platform occupying storage space and poor interaction with the vehicle structure. Specifically, the extension platform is installed on the support platform and has a storage position and an extension position. Combined with the automobile trunk structure, when the extension platform is in the storage position and the support platform is in a lower position, the extension component can serve as part of the trunk floor without occupying additional trunk storage space. When needed, the lifting component raises the support platform, moving the extension platform to above the trunk sill. Subsequently, the extension platform can be moved from the storage position to the extension position, allowing it to partially extend outside the vehicle. At the same time, the support legs are deployed to support the ground. The support legs and the support platform located on the vehicle jointly support the extension platform, enabling a stable operating platform to be formed with fewer support legs. It has a good interactive and cooperative relationship with the vehicle body, is easy to operate, and the extension platform is more stable.

[0006] In one possible implementation of this application, the support platform is provided with a receiving groove, and the receiving groove is open on one side in the horizontal direction, and the expansion platform is disposed in the receiving groove.

[0007] In this embodiment, the expansion platform is housed within the receiving groove on the support platform, and is confined by the receiving groove to prevent the expansion platform from shaking or shifting during vehicle operation. This improves the stability of the expansion platform integrated into the vehicle and prevents the integration of the expansion platform from deteriorating the vehicle's NVH performance. Simultaneously, the design of an opening on one side of the receiving groove meets the functional requirement of the expansion platform sliding horizontally, and also limits the sliding direction of the expansion platform, ensuring the stability and guiding accuracy of the expansion platform during sliding.

[0008] In one possible implementation of this application, the top of the support platform is recessed to form the receiving groove, and the top end face of the expansion platform does not extend beyond the top end face of the support platform.

[0009] In this embodiment, while satisfying the function of accommodating the expansion platform, the top of the support platform is recessed to form an accommodating groove. On the one hand, the top of the expansion platform can form the floor of the car trunk, reducing the size of the expansion component in the height direction, thereby reducing the installation space required for the expansion component. On the other hand, the exposed top of the expansion platform facilitates the horizontal movement of the expansion platform. Furthermore, the top end face of the expansion platform is limited to not exceeding the top end face of the support platform, preferably with both flush. This optimizes the appearance and prevents items stored in the trunk from scratching the expansion component, thus avoiding wear and tear on the items or the expansion component, and improving safety and durability.

[0010] In one possible implementation of this application, the bottom of the support platform is provided with an installation groove, the installation groove is located on the side of the receiving groove, and the lifting component is disposed in the installation groove.

[0011] In this embodiment, the lifting component is placed in the mounting groove at the bottom of the support platform, which effectively utilizes the space layout and facilitates the integrated design of the lifting component and the support platform. The size of the extension component is reduced in the height direction, improving the overall structural compactness and avoiding additional occupation of the luggage compartment interior space.

[0012] In one possible implementation of this application, the expansion platform is detachably mounted on the support platform.

[0013] In this embodiment, the extension platform placed on the support platform can not only form a stable operating platform in conjunction with the support platform, but it can also be detached from the support platform and supported only by the legs to form an operating platform structure independent of the car. This further enriches the function of the extension component, making it suitable for more usage scenarios and more applicable.

[0014] In one possible implementation of this application, the support leg is detachably mounted on the expansion platform; The expansion platform is provided with a first fixing structure, and the support legs are fixed to the first fixing structure to extend horizontally and be housed within the expansion platform; and / or, The expansion platform is provided with a second fixing structure, and the support legs are fixed to the second fixing structure to extend along the height direction to support the expansion platform.

[0015] In this embodiment, the support legs are detachable, allowing for more flexible storage and usage. Only the first fixed structure for storage and the second fixed structure for support need to be set independently. Compared to setting an adjustable structure, this structure is simpler, easier to design, reduces design costs, and is more reliable with a longer service life. At the same time, the support legs are easy to replace, facilitating repair or replacement in case of damage or loss.

[0016] In one possible implementation of this application, the first fixing structure includes a snap-fit ​​structure; and / or, The second fixing structure includes a hoop and a locking member, the locking member being used to lock the hoop.

[0017] In this embodiment, the specific structural configurations of the first and second fixing structures are defined. When the expansion platform is in its stowed position, a tight connection between the legs and the expansion platform is not required, and the legs need to be easily installed and removed. Therefore, the first fixing structure is configured as a snap-fit ​​structure for ease of operation. When the second fixing structure secures the legs, the legs support the expansion platform, thus requiring strong connection stability. Therefore, the second fixing structure is configured as a combination of a hoop and a locking element, satisfying the connection strength requirements between the legs and the expansion platform, while also facilitating the installation and removal of the legs.

[0018] In one possible implementation of this application, the legs are retractable.

[0019] In this embodiment, on the one hand, to reduce the space occupied by the support legs when they are stored in the extension platform, so as to facilitate the storage operation of the support legs, and on the other hand, to make the support legs suitable for different support heights, including but not limited to being suitable for cars of different heights or for different ground clearances of the extension platform, the support legs are set as a telescopic structure, which makes them more practical.

[0020] In one possible implementation of this application, the support leg includes a sleeve and a telescopic rod. The telescopic rod passes through the sleeve, and the sleeve has a plurality of limiting holes. The plurality of limiting holes are spaced apart along the extension direction of the sleeve. An elastic limiting member is provided outside the telescopic rod, and the elastic limiting member extends into the limiting hole to limit the telescopic rod.

[0021] In this embodiment, the telescopic structure of the support leg is defined as follows: the telescopic rod is telescopically disposed within the sleeve, and multiple limiting holes spaced apart along its extension direction are provided on the sleeve. The telescopic rod is provided with elastic limiting members corresponding to the limiting holes, so that the elastic limiting members can extend into the limiting holes to stably position the telescopic rod within the sleeve, thereby fixing the length of the support leg and providing strong stability. At the same time, the elastic limiting members can be easily driven out of the limiting holes to realize the telescopic operation of the support leg. This makes the support leg structure simple, easy to operate, and highly stable.

[0022] In one possible implementation of this application, the lifting assembly includes two cross-arranged support rods, which are rotatably connected at their intersection. One end of each support rod in the height direction is hinged to the platform and the vehicle, respectively, while the other ends are movably disposed on the platform and the vehicle in the horizontal direction.

[0023] In this embodiment, the lifting and lowering of the support platform is achieved by two cross-arranged support rods, that is, the lifting and lowering of the support platform is achieved by a cross-lifting structure. In addition to the structural stability, smooth lifting and lowering and stable lifting guidance of the cross-lifting structure, it has a smaller size in the height direction, which is suitable for minimizing the size of the extension component in the height direction and facilitates the installation of the extension component on the vehicle.

[0024] In one possible implementation of this application, a handle is provided on the support platform.

[0025] In this embodiment, in order to facilitate the lifting of the support platform, which is part of the luggage compartment floor, a handle is provided on the support platform, which has a simple structure and is easy to use.

[0026] Secondly, this application provides an automobile, which includes a vehicle body and an extension component. The vehicle body is provided with a luggage compartment. The extension component includes a support structure and an extension platform. The support structure includes a support platform and a lifting component. The support platform is installed in the luggage compartment of the automobile via the lifting component. The extension platform is installed on the support platform and is movable in the horizontal direction. In its movable stroke, it has at least a storage position placed on the support platform and an extension position partially extending out of the support platform. The bottom of the extension platform is provided with adjustable support legs. In the storage position, the support legs extend horizontally to be stored in the extension platform. In the extension position, the support legs extend vertically to support the suspended end of the extension platform. The extension component is installed in the luggage compartment.

[0027] The vehicle provided in this application embodiment integrates the aforementioned extension component. While addressing the issues of the extension platform occupying storage space and poor interaction with the vehicle structure, it expands the vehicle's functional scenarios. Specifically, the extension platform is installed on the support platform and has both a storage position and an extension position. Combined with the vehicle's trunk structure, when the extension platform is in the storage position and the support platform is in a lower position, the extension component can serve as the trunk floor without occupying additional trunk storage space. When needed, the lifting component raises the support platform, moving the extension platform above the trunk sill. The extension platform can then be moved from the storage position to the extension position, partially extending outside the vehicle. Simultaneously, the support legs are deployed to support the platform on the ground. The support legs, together with the support platform on the vehicle, support the extension platform, allowing for a stable operating platform with fewer support legs. This provides excellent interaction and coordination with the vehicle body, making operation convenient and the extension platform more stable.

[0028] In one possible implementation of this application, a groove is provided on the floor of the luggage compartment, the extension component is installed in the groove, and the top end face of the extension component does not extend beyond the floor of the luggage compartment.

[0029] In this embodiment, by creating a groove in the floor of the car's trunk, the expansion component is installed in the groove, so that the expansion component does not occupy the original storage space of the trunk, thus meeting the requirement of reducing the space occupied by the expansion component in the car's storage space.

[0038] Currently, vehicles have become the third space for users. Travel scenarios are becoming increasingly diverse, and demands are also increasing. Different tools are available on the market to meet the needs of different usage scenarios, but they are generally independent of the vehicle's structure. On the one hand, storing them in the car will occupy the car's storage space, and on the other hand, they have no functional interaction with the vehicle, resulting in poor ease of use. Furthermore, they may not be able to meet emergency needs if forgotten.

[0039] Therefore, this application provides an extension component, please refer to the embodiments thereof. Figures 1 to 9 The following describes the expansion components, including embodiments of the expansion components proposed in this application, in detail with reference to the specific accompanying drawings.

[0040] Please see Figure 3 and Figure 4 The extension component 100 provided in this application embodiment includes a support structure 1 and an extension platform 2. The support structure 1 includes a support platform 11 and a lifting component 12. The support platform 11 is installed in the trunk 201 of the car AOCA1000 via the lifting component 12. The extension platform 2 is installed on the support platform 11 and can be moved horizontally. In its movement stroke, it has at least a storage position on the support platform 11 and an extension position that partially extends out of the support platform 11. The bottom of the extension platform 2 is provided with an adjustable support leg 3. In the storage position, the support leg 3 extends horizontally to be stored in the extension platform 2. In the extension position, the support leg 3 extends vertically to support the suspended end of the extension platform 2.

[0041] The expansion component 100 provided in this application embodiment is applied to a car 1000, mainly used to integrate the expansion platform 2 into the car 1000, improving the problems of the expansion platform 2 occupying storage space and poor interaction with the vehicle structure. Specifically, the expansion platform 2 is installed on the support platform 11 and has both a storage position and an expansion position. Combined with the structure of the car 1000 trunk 201, when the expansion platform 2 is in the storage position and the support platform 11 is in a lower position, the expansion component 100 can serve as part of the floor 203 of the car 1000 trunk 201 without additionally occupying the trunk 201. 1. Storage space. When needed, the lifting assembly 12 raises the support platform 11, moving the extension platform 2 to above the door sill of the trunk 201. Then, the extension platform 2 can be moved from the storage position to the extension position, so that part of it extends out of the vehicle. At the same time, the support legs 3 are deployed to support the ground. The support legs 3 and the support platform 11 on the vehicle 1000 jointly support the extension platform 2, so that a stable operating platform can be formed with fewer support legs 3. It has a good interactive and cooperative relationship with the main body of the vehicle 1000, is easy to operate, and the extension platform 2 is more stable.

[0042] It should be noted that the specific number of the support legs 3 is not limited; there can be one, two, or even more, as long as sufficient stability is provided for the suspended end of the extension platform 2 after being supported by the support legs 3. Furthermore, the extension legs 3 do not need to be perpendicular to the ground or the extension platform 2 in the height direction; they only need to have a certain tilt angle to support the extension platform 2 between it and the ground, ensuring the stability of the extension platform 2.

[0043] In some embodiments of this application, the support platform 11 is provided with a receiving groove 111, and the receiving groove 111 is open on one side in the horizontal direction, and the expansion platform 2 is disposed in the receiving groove 111.

[0044] It should be noted that the way the expansion platform 2 is installed on the support platform 11 is not limited. For example, it can be placed on one end face of the support platform 11, or the receiving groove 111 can be opened on the support platform 11, as long as the expansion platform 2 is stably supported by the support platform 11 and the expansion platform 2 can move horizontally on the support platform 11.

[0045] In this embodiment, the expansion platform 2 is housed within the receiving groove 111 on the support platform 11, and is confined by the receiving groove 111 to prevent the expansion platform 2 from shaking or shifting during the operation of the vehicle 1000. This improves the stability of the expansion platform 2 integrated into the vehicle 1000 and prevents the integration of the expansion platform 2 from deteriorating the NVH performance of the vehicle 1000. Simultaneously, the design of the opening on one side of the receiving groove 111 meets the functional requirement of the expansion platform 2 sliding out in the horizontal direction, and can limit the sliding direction of the expansion platform 2, ensuring the stability and guiding accuracy of the expansion platform 2 during the sliding process.

[0046] In some embodiments of this application, the top of the support platform 11 is recessed to form the receiving groove 111, and the top end face of the extension platform 2 does not extend beyond the top end face of the support platform 11.

[0047] It should be noted that a horizontally extending receiving groove 111 is provided on the side of the support platform 11, and the expansion platform 2 placed in the receiving groove 111 can also satisfy the functions described above.

[0048] In this embodiment, while satisfying the function of the receiving groove 111 in accommodating the expansion platform 2, the top of the support platform 11 is recessed to form the receiving groove 111. On the one hand, the top of the expansion platform 2 can form the floor 203 of the trunk 201 of the car 1000, reducing the size of the expansion component 100 in the height direction, thereby reducing the installation space required for the expansion component 100. On the other hand, the top of the expansion platform 2 is exposed, which also facilitates the operation of the expansion platform 2 in the horizontal direction. Furthermore, the top end face of the expansion platform 2 is limited to not exceeding the top end face of the support platform 11, preferably the two are flush, which optimizes the appearance and avoids the objects stored in the trunk 201 from scratching the expansion component 100, causing wear and tear on the objects or the expansion component 100, thereby improving safety and durability.

[0049] In some embodiments of this application, the bottom of the support platform 11 is provided with an installation groove 112, the installation groove 112 is located on the side of the receiving groove 111, and the lifting component 12 is disposed in the installation groove 112.

[0050] It is understood that the mounting groove 112 and the receiving groove 111 are formed by bending and recessing the middle of a plate-like structure, so that the recessed area forms the receiving groove 111 to accommodate the expansion platform 2. The bent plate-like structure naturally forms the mounting groove 112 on the side of the receiving groove 111 to install the lifting component 12. This arrangement is convenient for processing and has a simple structure. Of course, in other embodiments of the support platform 11, the support platform 11 can also be set as a structure with a certain thickness, with grooves dug at its top and bottom to form the receiving groove 111 and the mounting groove 112, which can also meet the functional requirements of the receiving groove 111 and the mounting groove 112.

[0051] In this embodiment, the lifting component 12 is set in the mounting groove 112 at the bottom of the support platform 11, which effectively utilizes the space layout and facilitates the integrated design of the lifting component 12 and the support platform 11. The size of the extension component 100 is reduced in the height direction, improving the overall structural compactness and avoiding additional occupation of the internal space of the luggage compartment 201.

[0052] In some embodiments of this application, please refer to Figure 9 The expansion platform 2 is detachably mounted on the support platform 11.

[0053] It is understood that the expansion platform 2, when it can partially extend beyond the support platform 11, can fulfill the functional expansion proposed in this application. However, there are some usage scenarios that require the expansion platform 2 to be removed and used independently. Therefore, in this embodiment, the expansion platform 2 is limited to be detachably mounted on the support platform 11. Thus, there is no need to set an additional limiting structure to limit the extension length of the expansion platform 2. It should also be noted that, based on this, the number of legs 3 needs to be sufficient to stably support the expansion platform 2 on the ground when used independently. The specific number is not limited, but in this embodiment, the legs 3 are specifically set to four. When the expansion platform 2 partially extends beyond the support platform 11, only two legs 3 are used to support the suspended end of the expansion platform 2. When the expansion platform 2 is used independently, the four legs 3 are used to support the expansion platform 2, thereby ensuring the stability of the expansion platform 2.

[0054] In this embodiment, the extension platform 2 placed on the support platform 11 can not only form a stable operating platform in cooperation with the support platform 11, but it can also be detached from the support platform 11 and supported only by the support legs 3 to form an operating platform structure independent of the vehicle 1000, further enriching the function of the extension component 100, making it suitable for more usage scenarios and more applicable.

[0055] In some embodiments of this application, please refer to Figures 5 to 8 The support leg 3 is detachably mounted on the extension platform 2; the extension platform 2 is provided with a first fixing structure, and the support leg 3 is fixed to the first fixing structure to extend horizontally and be stored in the extension platform 2; the extension platform 2 is provided with a second fixing structure, and the support leg 3 is fixed to the second fixing structure to extend vertically to support the extension platform 2.

[0056] It is understood that the support leg 3 can be a structure independent of the extension platform 2 and the support platform 11. For example, the support leg 3 can be stored using an additional storage component and taken out for use when needed. However, this is obviously easy to lose. Therefore, in this embodiment, the first fixing structure is provided on the extension platform 2 to store the support leg 3. Specifically, the location of the first fixing structure is not limited. For example, it can be set at the top or bottom of the extension platform 2. In this embodiment, setting the support leg 3 at the bottom of the extension platform 2 allows the support leg 3 to be accommodated in the receiving groove 111, reducing the space occupied by the support leg 3 in the storage space of the car 1000. As for the setting of the second fixing structure, its location at the bottom of the extension platform 2 facilitates the stable support of the extension platform 2 by the support leg 3.

[0057] It should also be noted that when not in use, the support leg 3 is stored at the bottom of the expansion platform 2. To further ensure the stability of the expansion platform 2 within the receiving groove 111 and to ensure that the end face of the expansion platform 2 is flush with the end face of the support platform 11, some embodiments of this application also provide a support protrusion on the groove wall of the receiving groove 111. The support protrusion supports the edge of the expansion platform 2, ensuring the height of the expansion platform 2 within the receiving groove 111, and creating a gap between the support leg 3 stored at the bottom of the expansion platform 2 and the bottom of the receiving groove 111.

[0058] In this embodiment, the support leg 3 is detachable, which makes its storage and use more flexible. Only the first fixed structure for storage and the second fixed structure for support need to be set independently. Compared with setting an adjustable structure, this structure is simpler, easier to design, reduces design costs, and is more reliable and has a longer service life. At the same time, the support leg 3 is easy to replace, so as to facilitate repair or replacement when damaged or lost.

[0059] Please refer to some embodiments of this application. Figure 5 and Figure 7 The first fixing structure includes a snap-fit ​​structure 21; please refer to the following. Figure 6 and Figure 8 The second fixing structure includes a hoop 22 and a locking member 23, wherein the locking member 23 is used to lock the hoop 22.

[0060] It is understood that the specific configuration of the first fixing structure and the second fixing structure does not need to be limited, as long as it can substantially satisfy the requirement that the support leg 3 be installed on the expansion platform 2.

[0061] In this embodiment, the specific structural configurations of the first and second fixing structures are defined. When the expansion platform 2 is in the storage position, a tight connection between the support leg 3 and the expansion platform 2 is not required, and the support leg 3 needs to be easily installed and removed. Therefore, the first fixing structure is configured as the snap-fit ​​structure 21 for ease of operation. When the second fixing structure fixes the support leg 3, the support leg 3 supports the expansion platform 2, thus requiring strong connection stability. Therefore, the second fixing structure is configured as a combination of the clamp 22 and the locking member 23, satisfying the connection strength requirements between the support leg 3 and the expansion platform 2, while also facilitating the installation and removal of the support leg 3.

[0062] In some embodiments of this application, the support leg 3 is retractable.

[0063] Understandably, in some usage scenarios, where the distance between the extension platform 2 and the ground can be kept constant, the support leg 3 can be set to a fixed length. Alternatively, in other usage scenarios, the height of the support platform 11 can be adjusted by using the lifting component 12 to adjust the height of the extension platform 2, thereby adapting the distance between the extension platform 2 and the ground and the length of the support leg 3. In this case, the support leg 3 can also be set to a fixed length, but this is obviously not very practical.

[0064] In this embodiment, on the one hand, to reduce the space occupied by the support leg 3 when it is stored in the extension platform 2, so as to facilitate the storage operation of the support leg 3, and on the other hand, to make the support leg 3 suitable for different support heights, including but not limited to being suitable for different heights of automobiles 1000 or different ground clearances of the extension platform 2, the support leg 3 is set as a telescopic structure, which is more practical.

[0065] In some embodiments of this application, please refer to Figure 4 The support leg 3 includes a sleeve 31 and a telescopic rod 32. The telescopic rod 32 passes through the sleeve 31, and the sleeve 31 has a plurality of limiting holes 311. The plurality of limiting holes 311 are spaced apart along the extension direction of the sleeve 31. An elastic limiting member 321 is provided outside the telescopic rod 32. The elastic limiting member 321 extends into the limiting hole 311 to limit the telescopic rod 32.

[0066] It is understandable that the telescopic structure of the support leg 3 can be set as a complex telescopic support structure such as a pneumatic rod or a hydraulic rod in some other embodiments, but the cost is obviously high. In other embodiments, it can also be set as multiple connecting rods, and the overall length after the multiple connecting rods are connected can be different by different connection points, but it is obviously not convenient to disassemble and store.

[0067] It should be noted that the elastic limiting member 321 can be an elastic deformation member disposed on the periphery of the telescopic rod 32. However, in this embodiment, the telescopic rod 32 is hollow, and the elastic limiting member 321 includes an elastic member and a limiting member. The telescopic rod 32 has an opening, and the limiting member can partially extend out of the opening. One end of the elastic member abuts against the inner wall of the telescopic rod 32, and the other end abuts against the limiting member, so as to maintain the state in which the limiting member partially extends out of the opening, thereby realizing the function of the elastic limiting member 321.

[0068] In this embodiment, the telescopic structure of the support leg 3 is defined as follows: the telescopic rod 32 is telescopically disposed within the sleeve 31, and a plurality of limiting holes 311 spaced apart along its extension direction are provided on the sleeve 31. The telescopic rod 32 is provided with elastic limiting members 321 corresponding to the limiting holes 311, so that the elastic limiting members 321 can extend into the limiting holes 311 to stably position the telescopic rod 32 within the sleeve 31, thereby fixing the length of the support leg 3. This provides strong stability, and at the same time, it is easy to drive the elastic limiting members 321 out of the limiting holes 311 to realize the telescopic operation of the support leg 3. This makes the support leg 3 simple in structure, easy to operate, and highly stable.

[0069] In some embodiments of this application, please refer to Figure 3 and Figure 4 The lifting assembly 12 includes two cross-arranged support rods 121, which are rotatably connected at their intersection. The opposite ends of the two support rods 121 in the height direction are respectively hinged to the support platform 11 and the vehicle 1000, and the opposite ends are respectively movably arranged in the horizontal direction on the support platform 11 and the vehicle 1000.

[0070] It should be noted that the lifting assembly 12 needs to maintain its lifting height during the lifting process to ensure the support platform 11 provides support for the extension platform 2. Therefore, the relative movement between the two support rods 121 needs to be damped or limited. For example, a strut can be installed between the two support rods 121 to limit the intersection angle of the two support rods 121, thereby limiting the height of the lifting assembly 12. Of course, other structures can also be used to limit the movement between the two support rods 121, as long as the functional requirements are met, and no limitation is made here. As for the damping structure, it can be set at the hinge between the support rod 121 and the support platform 11 or the vehicle 1000, or at the hinge between the two support rods 121, or in the area where the support rod 121 moves horizontally relative to the support platform 11 or the vehicle 1000. No limitation is made here, and the specific setting of the damping structure is also not limited. It can be a viscous structure or an elastic element, as long as the functional requirements are met.

[0071] In this embodiment, the lifting and lowering of the support platform 11 is achieved by two cross-arranged support rods 121, that is, the lifting and lowering of the support platform 11 is achieved by a cross-lifting structure. In addition to the structural stability, smooth lifting and lowering and stable lifting guidance of the cross-lifting structure, it has a smaller size in the height direction, which is suitable for minimizing the size of the extension component 100 in the height direction and facilitates the installation of the extension component 100 on the vehicle 1000.

[0072] In some embodiments of this application, please refer to Figure 1 and Figure 2 The support platform 11 is provided with a handle 113.

[0073] In this embodiment, in order to facilitate the lifting of the support platform 11, which is part of the floor 203 of the luggage compartment 201, a handle 113 is provided on the support platform 11, which has a simple structure and is easy to use.

[0074] It should be noted that the handle 113 is mainly for facilitating the lifting of the support platform 11, so as to avoid the support platform 11 being embedded in the trunk 201 of the car 1000 and inconvenient to operate. In addition, it is also possible to open an operating groove for manual operation on the top end face of the support platform 11, or to set other operating components to operate the support platform 11. There is no limitation here, as long as the functional requirement of facilitating the lifting of the support platform 11 mentioned above is met.

[0075] This application also provides a car 1000, please refer to... Figures 1 to 4 The vehicle 1000 includes a vehicle body 200 and an extension component 100.

Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.

[0077] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.

[0078] In some embodiments of this application, a groove 202 is provided on the floor 203 of the luggage compartment 201, the extension component 100 is installed in the groove 202, and the top end face of the extension component 100 does not extend beyond the floor 203 of the luggage compartment 201.

[0079] In this embodiment, by creating a groove 202 on the floor 203 of the trunk 201 of the vehicle 1000, the expansion component 100 is installed in the groove 202, so that the expansion component 100 does not occupy the original storage space of the trunk 201, thus meeting the requirement of reducing the storage space occupied by the expansion component 1000.
