Detailed implementation manners
[0024] Next, in combination with the attached Figure 1 - attached Figure 4 , the technical solutions in the embodiments of the present invention will be clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can fully combine the embodiments of the present invention to obtain other embodiments without creative labor, and these embodiments are also within the protection scope of the present invention.
[0025] The inventors of the present application found that although a pickup truck camper, as a small house installed on the cargo box of a pickup truck, can instantly increase the storage space and living function of the pickup truck, when using the existing side expansion device, due to the relatively high installation height of the pickup truck camper itself, there are often problems of excessive height, which brings inconvenience to users and reduces the actual use effect and convenience of the expansion device. Therefore, the present application mainly adopts the following solutions to achieve the effects of reducing the height of the expansion device, improving the use convenience and stability, and being able to flexibly adjust the height according to user needs.
[0026] An embodiment of the present application discloses a pickup truck camper expansion device. Referring to Figure 1 , it includes a window 1 opened on the side wall of the camper and a storage table 2 provided at the position of the window 1. Two connecting plates 3 are fixedly provided on the storage table 2 by bolts. The two connecting plates 3 are respectively arranged on both sides of the storage table 2. Support rods 4 are rotatably provided on both connecting plates 3. The rotation axes of the two support rods 4 are collinear. Two sets of rotating structures 5 are provided on the window 1. The rotating structures 5 correspond to the support rods 4 one by one and are respectively used to drive the corresponding support rods 4 to rotate.
[0027] Reference Figure 1 , the storage table 2 includes a bottom plate and a tabletop laid on the bottom plate. The bottom plate is made of wood or plastic, and the tabletop is made of an aluminum alloy plate, so that the storage table 2 has good strength and lightness performance.
[0028] Reference Figure 1 , a stop strip 11 is arranged along the circumferential direction of the window 1 inside the window 1. The function of the stop strip 11 is to prevent a gap from being generated between the storage table 2 and the window 1 when the storage table 2 is in the closed state. The size of the stop strip 11 can be adjusted according to the actual situation to ensure that the storage table 2 closely fits the inner wall of the window 1 when in the closed state. The material of the stop strip 11 can be selected from plastics, rubber or soft materials to ensure its flexibility and durability.
[0029] Reference Figure 2 , the support rod 4 includes a first rod body 41 and a second rod body 42. Both the first rod body 41 and the second rod body 42 are made of aluminum alloy material. The rotating structure 5 is connected to the first rod body 41, and the connecting plate 3 is hinged to the second rod body 42. A fixing member for fixing the second rod body 42 is arranged on the first rod body 41. The fixing member includes a screw 43. A plurality of through holes 421 for the screw 43 to pass through are formed on the second rod body 42. The through holes 421 are distributed along the length direction of the second rod body 42. A plurality of threaded holes 411 adapted to the screw 43 are formed on the first rod body 41. The threaded holes 411 are distributed along the length direction of the first rod body 41. The distance between two adjacent through holes 421 on the second rod body 42 is equal to the distance between two adjacent threaded holes 411 on the first rod body 41. When the second rod body 42 is fixed to the first rod body 41, the length directions of the first rod body 41 and the second rod body 42 are parallel, so that the length of the support rod 4 can be flexibly adjusted to meet different requirements.
[0030] When the expansion device is installed, by adjusting the relative positions of the first rod body 41 and the second rod body 42, the length of the support rod 4 is further adjusted. Then, according to the length of the support rod 4, the storage table 2 is fixed on the connecting plate 3 through bolts. When the expansion device is closed, the position of the storage table 2 corresponds to the position of the window 1, so that the height can be adjusted within a certain range according to the user's needs, which is applicable to users of different heights and body types, further improving its practicality.
[0031] Reference Figure 2 、 3 , a limiting member for limiting the maximum rotation angle of the support rod 4 is arranged on the connecting plate 3. The limiting member includes a limiting block 31. The limiting block 31 is fixedly arranged on the connecting plate 3 and is used to abut against the second rod body 42 to ensure that the length direction of the support rod 4 is perpendicular to the storage table 2 when the support rod 4 is at the maximum rotation angle. The material of the limiting block 31 can be selected from stainless steel, plastic or hard alloy. The size of the limiting block 31 can be adjusted according to the actual situation to ensure effectively limiting the rotation range of the support rod 4.
[0032] ReferenceFigure 1 , 2 , the rotating structure 5 includes a mounting plate 51, a first connecting rod 52 and a second connecting rod 53. The mounting plate 51 is fixed to the inner side wall of the window 1 by bolts. The first connecting rod 52 and the second connecting rod 53 are both hinged to the mounting plate 51. The length directions of the first connecting rod 52 and the second connecting rod 53 are parallel and their lengths are equal. The first connecting rod 52 and the second connecting rod 53 are both hinged to the first rod body 41. The connection line formed by the hinge point of the first connecting rod 52 and the mounting plate 51 and the hinge point of the second connecting rod 53 and the mounting plate 51 is parallel to the side wall of the housing box. A parallelogram structure is formed among the mounting plate 51, the first connecting rod 52, the second connecting rod 53 and the first rod body 41, so that when the rotating structure 5 drives the support rod 4 to rotate, the length direction of the support rod 4 remains parallel to the side wall of the housing box.
[0033] Refer to Figure 2 , a damping cylinder 521 is provided on the first connecting rod 52. The cylinder part of the damping cylinder 521 is hinged to the first connecting rod 52, and the piston rod of the damping cylinder 521 is hinged to the first rod body 41. The maximum rotation angle between the first rod body 41 and the first connecting rod 52 can be limited through the damping cylinder 521, improving the stability after the storage table 2 is unfolded. Moreover, through the setting of the damping cylinder 521, a buffering effect can also be achieved, making the movement of the support rod 4 smoother and avoiding violent shaking.
[0034] Refer to Figure 1 , 4 , a locking assembly for fixing the storage table 2 is provided at the window 1. The locking assembly includes a lock catch 12 and a rotating buckle 21. The lock catch 12 is arranged at the top of the window 1 for locking the storage table 2. The rotating buckle 21 is rotatably arranged on the storage table 2. A handle 22 is rotatably arranged on the storage table 2. The rotating shaft of the handle 22 penetrates through the storage table 2 and is fixedly connected to the rotating buckle 21. By rotating the handle 22, the rotating buckle 21 is driven to rotate, so that the rotating buckle 21 rotates to the inner side of the stop bar 11, and then through the interaction between the lock catch 12 and the rotating buckle 21, the fixation of the storage table 2 is realized.
[0035] The implementation principle of an extended device for a pickup housing box in an embodiment of the present application is as follows: when using the extended device, first loosen the lock catch 12 at the top of the window 1, rotate the handle 22 to cancel the locking of the rotating buckle 21 to the stop bar 11, drive the support rod 4 to rotate through the rotating structure 5. At this time, the storage table 2 can follow the rotating structure 5 and move downward, and then drive the storage table 2 to turn downward to unfold the storage table 2. When the limit block 31 on the connecting plate 3 abuts against the second rod body 42, the maximum rotation angle is reached between the connecting plate 3 and the second rod body 42. At this time, the storage table 2 is in a horizontal state, and the storage table 2 is located below the window 1, thereby reducing the height of the extended device to facilitate the user to use and improving the practicability and use convenience of the extended device.
[0036] The above are all preferred embodiments of this application, and do not limit the protection scope of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
