Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings and the detailed description.

As shown in fig. 1, in the expanded state of the vehicle-mounted room, the space in the room is substantially rectangular. A lifting mechanism 80 is connected between the roof 50 and the floor 60. Roof 50 includes four roof panels, a first roof panel 51, a second roof panel 52, a third roof panel 53, and a fourth roof panel 54. As shown in fig. 2 and 3, when the vehicle-mounted house is stored, the lifting mechanism 80 is used to drive the roof 50 to descend to the position shown in fig. 2, at this time, the roof 50, the side walls and some facilities in the house are all stacked and supported on the floor 60, and then the roof can be further separated along the seams of the roof plates and then stacked together, and finally the stacked storage state shown in fig. 3 is achieved. Of course, other numbers of roof tiles may be similarly stowed.

As shown in fig. 4, the lifting mechanism 80 is connected between the roof 50 and the floor 60, the lifting mechanism 80 includes a driving device 80c and four lifting devices, and the driving device 80c can drive the lifting devices to lift, so as to drive the roof 50 to lift, thereby facilitating the unfolding and storage of the vehicle-mounted house.

Of the four lifting devices, two are longitudinal lifting devices 80a connected to the longitudinal side of the roof 50, and the other two are transverse lifting devices 80b connected to the transverse side of the roof 50, and in the illustrated embodiment, the Front-Back direction is the longitudinal direction (i.e., Front-Back direction in the figure) and the Left-Right direction (i.e., Left-Right direction in the figure) is the transverse direction. Under the state that the vehicle-mounted house is unfolded, the two longitudinal lifting devices 80a are positioned on the outer sides of the longitudinal side walls of the vehicle-mounted house, and the two transverse lifting devices 80b are positioned on the outer sides of the transverse side walls of the vehicle-mounted house.

Elevating gear is all connected to longitudinal side and horizontal side at roof 50, the longitudinal side and the horizontal side homoenergetic of exhibition receipts in-process roof 50 like this can reliably be supported, thereby make roof 50 can the vertical lift, be difficult to collapse or warp, especially roof 50 is in the condition of all forming the contained angle on longitudinal and horizontal (as figure 4, roof 50 is from forming contained angle theta on longitudinal, from forming contained angle gamma on horizontal), prevent that roof 50 from collapsing or the effect of warping is more showing, and can also promote the ability that external force such as the anti crosswind of on-vehicle room disturbed.

As shown in fig. 4, each of the longitudinal elevating means 80a and the lateral elevating means 80b includes an X-shaped cross arm 81, and the X-shaped cross arm 81 includes two arms which cross each other in an X-shape and are relatively rotatably connected together at a crossing point. It is preferable to provide each of the elevating means as a symmetrical structure vertically symmetrical about the intersection point of its X-shaped cross arm 81, so that the motion matching is easier and the motion interference does not easily occur.

As shown in fig. 5, 6 or 7, each of the longitudinal lifter 80a and the lateral lifter 80b includes an upper guide 82 and two upper sliders 84 (only one upper slider 84 is shown in fig. 5 and 6), the upper guide 82 may be a guide rod, a guide rail, a guide sleeve, or the like, and the upper sliders 84 may be a sliding sleeve, a slider, or the like. Each of the upper guides 82 includes two upper guide portions 82a, and two upper sliding pieces 84 connected to the two upper guide portions 82a of the upper guides 82, respectively, to be slidable along the upper guide portions 82 a.

The upper ends of the two arms of the X-shaped cross arm 81 are hinged to the two upper sliders 84, respectively, in the embodiment shown in fig. 5 and 6, the upper ends of the two arms of the X-shaped cross arm 81 are hinged directly to the two upper sliders 84, and in the embodiment shown in fig. 7, the upper ends of the two arms of the X-shaped cross arm 81 are hinged indirectly to the two upper sliders 84 through the elastic connector 88, and the advantageous effects of the elastic connector 88 will be described in detail later.

The two upper guide portions 82a of the upper guide 82 are connected to the two roof panels, respectively, and may be fixedly connected to or hinged to the peripheral frame of the roof panel, and in the process of being hinged, the upper guide portions 82a may rotate relative to the roof 50 during the lifting process. In the solution shown in fig. 5, a fixed connection is used, in which the two upper guides 82a are broken at the seams of the roof panels so as not to interfere with the stacked housing of the roof 50. In the embodiment shown in fig. 6, a hinge is used, in which two upper guide portions 82a are connected by a socket portion 82b at the joint of the roof panel, and the two upper guide portions 82a are disconnected at the joint of the roof panel by removing or sliding the socket portion 82b during storage, so that the stacked storage of the roof 50 is not affected.

As shown in fig. 8, each of the longitudinal lifting device 80a and the transverse lifting device 80b includes a lower guide 83 and two lower sliders 85 (only one lower slider 85 is shown in fig. 8), the lower guide 83 may be a guide rod, a guide rail, a guide sleeve, etc., and the lower slider 85 may be a sliding sleeve, a slider, etc. Each lower guide 83 includes two lower guide portions 83a, two lower sliders 85 are respectively connected to the two lower guide portions 83a of the lower guide 83 (as understood in conjunction with fig. 10) and are slidable along the lower guide portions 83a, and lower ends of the two arms of the X-shaped cross arm 81 are respectively hinged to the two lower sliders 85.

As shown in fig. 9 and 10, the lower guide portion 83a is connected to the floor 60, and may be disposed outside the floor 60 and fixedly connected to the peripheral frame of the floor 60. The two lower guide portions 83a are cut at the joint of the floor panel blocks to avoid affecting the stacking accommodation of the floor panel 60. The lower guide portion 83a of the longitudinal lifting device 80a extends in the horizontal longitudinal direction to guide the lower sliding member 85 of the longitudinal lifting device 80a to slide in the horizontal longitudinal direction, and the lower guide portion 83a of the lateral lifting device 80b extends in the horizontal lateral direction to guide the lower sliding member 85 of the lateral lifting device 80b to slide in the horizontal lateral direction.

As shown in fig. 9 and 10, the driving device 80c includes a power element (not shown) and four driving shafts 87, each driving shaft 87 includes a plurality of driving shaft segments 87a (two driving shaft segments in the figure), and the driving shaft segments 87a are connected into a complete driving shaft 87 at the floor seam by a sliding sleeve structure or the like. Four drive shafts 87 drive four lifting devices, respectively. As shown in fig. 8, the lower guide portion 83a is provided as a guide sleeve, and the lower guide portion 83a is provided with a notch S along the axial direction. As shown in fig. 9, each of the driving shafts 87 passes through the two lower guide portions 83a of one of the lower guide members 83. The drive shaft 87 is provided with male screws having different rotation directions at positions corresponding to the two lower guides 83 a. The lower sliding member 85 is fitted over the lower guide portion 83a, and a protrusion is provided on the lower sliding member 85, which protrudes into the lower guide portion 83a through the axial slot S, and is hinged to a threaded sleeve on the external thread of the driving shaft 87 (the external thread, the protrusion, and the threaded sleeve are not shown), so that the rotational motion of the driving shaft 87 can be converted into the linear sliding motion of the lower sliding member 85.

When the driving shaft 87 rotates, the two lower sliding pieces 85 of each lifting device slide in opposite directions or back to back, so that the upper ends of the two support arms of the X-shaped cross arm 81 rise or fall, and the roof 50 is driven to rise or fall; after the roof 50 is raised or lowered to the target height, the driving shaft 87 stops rotating, and the driving shaft 87 and the lower sliding piece 85 are self-locked by the threads, so that the roof 50 is kept at the target height.

As shown in fig. 10, the four driving shafts 87 can be linked by a transmission assembly including a plurality of gears 86, which can be bevel gears or bevel gears, and two gears 86 engaged with each other are respectively disposed at the ends of two adjacent driving shafts 87. The four lifting devices can be driven to lift simultaneously only by arranging one power element, the structure is simplified, the lifting pace of the four lifting devices is consistent, and if the lifting pace of the four lifting devices is inconsistent, the roof 50 is easy to warp or is easy to block during lifting.

In general, the longitudinal length and the transverse width of the on-board compartment are not equal, in this case, in order to support the roof 50 more firmly, in the unfolded state of the on-board compartment, the longitudinal span of the X-shaped cross arm 81 of the longitudinal lifting device 80a and the transverse span of the X-shaped cross arm of the transverse lifting device 80b are not equal, and if the longitudinal length of the on-board compartment is greater than the transverse width thereof, the longitudinal span of the X-shaped cross arm 81 of the longitudinal lifting device 80a is greater than the transverse span of the X-shaped cross arm of the transverse lifting device 80b, and conversely, the longitudinal span of the X-shaped cross arm 81 of the longitudinal lifting device 80a is less than the transverse span of the X-shaped cross arm of the transverse lifting device 80 b. Meanwhile, for the convenience of storage, the arm length of the X-shaped cross arm 81 of the lateral elevating device 80b is preferably shorter than the lateral width of the vehicle-mounted room after storage, and therefore, the arm length of the X-shaped cross arm 81 of the lateral elevating device 80a is preferably set shorter than the arm length of the X-shaped cross arm 81 of the longitudinal elevating device 80 b.

However, by making the longitudinal span of the X-shaped cross arm 81 of the longitudinal lifting device 80a different from the transverse span of the X-shaped cross arm of the transverse lifting device 80b, the transmission ratio of the longitudinal and transverse drive shafts 87 is obviously different from 1, furthermore, the arm length of the X-shaped cross arm 81 of the transverse lifting device 80a is different from the arm length of the X-shaped cross arm 81 of the longitudinal lifting device 80b, with this arrangement, the lifting heights of the upper ends of the support arms of the longitudinal lifting device 80a and the transverse lifting device 80b are likely to be different during the lifting process, so that the roof 50 is easily warped and deformed during its lifting and lowering, and in order to prevent this problem, the above-mentioned elastic coupling member 88 may be provided at the upper arm end of the X-shaped cross arm 81 so that the upper arm end of the X-shaped cross arm 81 is indirectly hinged to the upper slider 84 through the elastic coupling member 88. Specifically, the elastic link 88 may be provided only at the upper end of the X-shaped cross arm 81 of the lateral elevating device 80b (in the illustrated embodiment), the elastic link 88 may be provided only at the upper end of the X-shaped cross arm 81 of the longitudinal elevating device 80a, or the elastic link 88 may be provided at the upper end of both the X-shaped cross arm 81 of the longitudinal elevating device 80a and the X-shaped cross arm 81 of the lateral elevating device 80 b.

As shown in fig. 7, the elastic link 88 includes an elastic portion 88b and a hinge portion 88a, the hinge portion 88a is hinged to the upper slider 84, and the hinge portion 88a is also slidably connected to the upper arm end of the X-shaped cross arm 81 via the elastic portion 88 b. The elastic part 88b can be stretched or compressed along the length direction of the support arm, so that the hinge part 88a can slide or reset along the length direction of the support arm, thereby making up the lifting height difference of the upper ends of the support arms of the longitudinal lifting device 80a and the transverse lifting device 80b and avoiding the problem of buckling deformation of the roof during the lifting process.

The elastic portion 88b can be implemented in various ways, for example, one end of the upper guiding portion 82a is hinged to the roof 50, and the other end is connected to the roof 50 through an elastic member, so that the upper guiding portion 82a can deflect relative to the roof 50 during the lifting process to compensate for the difference in lifting height between the upper ends of the arms of the longitudinal lifting device 80a and the lateral lifting device 80 b. In any event, the resilient portion 88b is allowed to be stretched along the length of the arm during the raising and lowering process by an amount that is close to the amount that it is compressed, which means that the resilient portion 88b will pass through the midpoint null position from the stretched state to the compressed state. Such as unequal included angles beta of the longitudinal and lateral guides 82a and/or unequal arm lengths of the longitudinal and lateral X-shaped cross arms 81. When the roof 50 is always in the elastically allowable deformation range from the stretched state to the compressed state, the difference in the lifting height of the upper ends of the arms of the longitudinal lifting device 80a and the lateral lifting device 80b is actually compensated for by the elastic portion 88 b. In this case, the elastic portion 88b may not be provided.

Specifically, the upper guide 82 of each lifting device may be disposed parallel to the lower guide 83 thereof. Alternatively, the upper guide 82 of the partial elevating device is disposed in parallel with the lower guide 83 thereof, and the upper guide 82 of the partial elevating device is disposed in non-parallel with the lower guide 83 thereof. Alternatively, the upper guide 82 of each elevator apparatus is not parallel to the lower guide 83 thereof.

In the solution shown in fig. 5, the upper guide 82 and the lower guide 83 are not parallel, the two upper guide portions 82a of the upper guide 82 form an angle β with each other, and the two upper guide portions 82a form an angle α with the lower guide 83. Preferably, the upper guide 82 of the at least one longitudinal lifting device 80a is disposed non-parallel to the lower guide 83 thereof, and the upper guide 82 of the at least one lateral lifting device 80b is disposed non-parallel to the lower guide 83 thereof. By the design, the capability of resisting the lateral wind along the transverse direction and the lateral wind along the longitudinal direction of the vehicle-mounted house is improved to some extent, so that the vehicle-mounted house is integrally more stable.

With the nonparallel arrangement, in the vehicle-mounted room unfolded state, after the drive shaft 87 stops rotating, as shown in fig. 11:

for the longitudinal lifting device 80a, the upper guide 82 and the upper slider 84 are respectively limited by the lower guide 83 and the lower slider 85 in a longitudinal vertical plane H passing through the axis of the upper guide 82, and the roof 50 cannot move in the direction of a-a' in the longitudinal vertical plane H; meanwhile, since the two upper guide portions 82a of the upper guide 82 of the longitudinal elevating device 80a form an included angle β, and the two upper sliding members 84 are respectively hinged to the two upper guide portions 82a forming the included angle β, in a locked state, the roof 50 cannot move in the direction of B-B', and the roof 50 cannot be deflected in the direction of M in the longitudinal vertical plane H.

Similarly, for the transverse elevating device 80b, in a transverse vertical plane V passing through the axis of the upper guide 82, the upper guide 82 and the upper slider 84 are respectively limited by the lower guide 83 and the lower slider 85, and in the transverse vertical plane H, the roof 50 cannot move in the direction of E-E'; meanwhile, since the two upper guide portions 82a of the upper guide 82 of the transverse elevating device 80b form an included angle β, and the two upper sliding members 84 are respectively hinged to the two upper guide portions 82a forming the included angle β, which is a clamping state, the roof 50 cannot move in the direction of D-D';

although the elastic connecting piece 88 is provided at the upper end of the X-shaped cross arm 81 of the lateral lifting device 80b, the elastic connecting piece 88 can slide relative to the X-shaped cross arm 81, the X-shaped cross arms 81 of the longitudinal lifting devices 80a at two sides prevent one of the two upper sliding pieces 84 of the lateral lifting device 80b from sliding downwards in the direction C and the other one of the two upper sliding pieces 84 of the lateral lifting device 80b from sliding upwards in the direction C' (vice versa), i.e. prevent the roof 50 from deflecting in the direction N;

therefore, by adopting the above nonparallel arrangement scheme, the roof 50 can not generate horizontal movement, vertical movement and deflection in the vertical plane H and the horizontal vertical plane V, so that the roof 50 can vertically lift relative to the floor 60 without additionally arranging other limiting mechanisms in the process of lifting the roof 50, and the vehicle-mounted house after being unfolded has stronger capability of resisting the interference of external forces such as lateral wind and the like, so that the stability is high.

In the solution shown in fig. 6, the upper guide 82 is arranged parallel to the lower guide 83, and both upper guide portions 82a of the upper guide 82 are parallel to the lower guide 83. And the parallel arrangement is adopted, so that the motion matching is easier, and the motion interference is not easy to occur.

Specifically, as shown in fig. 12, the X-shaped cross arm 81 includes two arms which cross each other in an X-shape and are hinged together at the crossing position by a hinge structure. Each arm comprises two arm segments, one arm (hereinafter referred to as the first arm) comprising a first arm segment 81a and a fourth arm segment 81d and the other arm (hereinafter referred to as the second arm) comprising a second arm segment 81b and a third arm segment 81c in the illustrated embodiment. First arm segment 81a and second arm segment 81b are connected to roof 50 and third arm segment 81c and fourth arm segment 81d are connected to floor 60.

The two sections of each arm are detachably connected together, i.e. the two sections of each arm can be connected together and separated. By the design, the two arm sections of each support arm can be stacked and stored together with other parts (a roof 50, a floor 60 and the like) of the vehicle-mounted house, so that the whole vehicle-mounted house can be folded from the state shown in fig. 2 to the state shown in fig. 3 along the seam of a roof plate without independently disassembling the X-shaped cross arm 81 for storage, and the storage and expansion operation of the vehicle-mounted house is more convenient and faster. The two arm sections of the arm are separated for storage, and the method for lifting after connection is not limited to the illustrated embodiment.

Specifically, the two sections of the arm sections of each support arm can be directly inserted together or indirectly inserted together through the transition piece. In the illustrated embodiment, a first transition piece 81e and a second transition piece 81f are provided, the first arm segment 81a and the fourth arm segment 81d being plugged together by the first transition piece 81e, and the second arm segment 81b and the third arm segment 81c being plugged together by the second transition piece 81 f.

Specifically, as shown in fig. 12-15 and 16-18, the connection position of the two arm segments of each arm can be located at the intersection position of the two arms. Alternatively, as shown in fig. 19-21, the connection position of the two arm segments of each arm may be offset from the intersection position of the two arms.

Specifically, in the embodiment shown in fig. 12-15 and 16-18, the hinge structure includes a first hinge 81g, a second hinge 81h and a hinge shaft (not shown).

A first arm section 81a of the first arm connected with the roof 50 and a third arm section 81c of the second arm linked with the floor 60 are hinged together by a first hinge 81 g; the second arm section 81b of the second arm, which is connected to the roof 50, and the fourth arm section 81d of the first arm, which is connected to the floor 60, are articulated together by means of a second articulation 81 h. With this arrangement, as shown in fig. 6, when the two arm sections (the first arm section 81a and the fourth arm section 81d) of the first arm are separated and the two arm sections (the second arm section 81b and the third arm section 81c) of the second arm are separated, the first arm section 81a of the first arm connected to the roof 50 is still hinged to the third arm section 81c of the second arm connected to the floor 60, and the fourth arm section 81d of the first arm connected to the floor 60 is still hinged to the second arm section 81b of the second arm connected to the roof 50, so that the storage is facilitated and a pulling force can be generated to the roof 50 and the floor 60, which can help the stacked and stored vehicle-mounted rooms to maintain the stacked configuration without being easily scattered.

After the four arm segments are connected, the first arm segment 81a and the fourth arm segment 81d are collinear, the second arm segment 81b and the third arm segment 81c are collinear, and meanwhile, the first arm segment 81a and the third arm segment 81c are hinged through a first hinge portion 81g, and the second arm segment 81b and the fourth arm segment 81d are hinged through a second hinge portion 81 h. After the two arms are hinged, the hinge axis of the first hinge 81g, the hinge axis of the second hinge 81d, and the axis of the hinge shaft coincide (see L in fig. 15).

Figure 15 illustrates one configuration of the hinge. In this embodiment, the first hinge 81g includes a first guide groove M1 and a first slider N1, the first guide groove M1 is provided on the first arm segment 81a, and the first slider N1 is provided on the third arm segment 81 c. The first guide groove M1 is engaged with the first slider N1, and the first guide groove M1 guides the first slider N1 to slide along a predetermined trajectory around the hinge axis of the first hinge 81g, thereby hinging the first arm segment 81a and the third arm segment 81c together.

Similarly, the second hinge 81h includes a second guide groove M2 and a second slider N2, the second guide groove M2 is provided on the fourth arm segment 81d, and the second slider N2 is provided on the second arm segment 81 b. The second guide groove M2 is engaged with the second slider N2, and the second guide groove M2 guides the second slider N2 to slide along a predetermined trajectory around the hinge axis of the second hinge 81h, thereby hinging the second arm segment 81b and the fourth arm segment 81d together.

An avoidance space for the hinge shaft to pass through is reserved between the first guide groove M1 and the second guide groove M2, and the hinge shaft sequentially passes through the first transition piece 81e, the avoidance space and the second transition piece 81f, so that the two support arms are hinged together.

The end parts of the first guide groove M1 and the second guide groove M2 can be respectively provided with a port Mk, and under the state that the hinge axis of the first hinge part 81g is overlapped with the hinge axis of the second hinge part 81d, the port of the first guide groove M1 is over against the port of the second guide groove M2, so that the first sliding block N1 slides into the second guide groove M2 from the first guide groove M1 through the port, and similarly, the second sliding block N2 can slide into the first guide groove M1 from the second guide groove M2 through the port, and thus, the design can ensure that two support arms can swing and rotate in a large angle relatively.

The guide groove and the sliding block can be in limit fit along the hinge axis, so that the relative positions of the guide groove and the sliding block in the direction along the hinge axis are fixed. In the scheme shown in the figure, the guide groove is of a groove structure with a T-shaped cross section, the sliding block is a T-shaped block, and the guide groove and the sliding block are in limit fit by utilizing a large-size end of the T shape. Of course, the manner in which the limit fit is achieved is not limited to this. For example, the guide groove is arranged to be a groove with a dovetail-shaped or L-shaped cross section, and the sliding block is arranged to be a dovetail block or an L-shaped block, so that the limiting matching of the guide groove and the sliding block can be realized.

The hinge structure shown in fig. 15 has high reliability, and the structural strength of the support arm can be increased to a certain extent by the concave-convex matching of the guide groove and the slide block.

Figure 18 illustrates another construction of the hinge. In this embodiment, the hinge comprises two orifice plates N3 and a hollow shaft N4.

The two perforated plates N3 of the first hinge 81g are respectively arranged on the first arm segment 81a and the third arm segment 81c and avoid the sockets on the arm segments for inserting the transition pieces, and both ends of the hollow shaft N4 are respectively inserted into or aligned with the openings of the two perforated plates N3, thereby hinging the first arm segment 81a and the third arm segment 81c together.

The two perforated plates N3 of the second hinge 81h are respectively arranged on the second arm segment 81b and the fourth arm segment 81d and leave free the sockets for the insertion of the transition piece on the arm segments, and the two ends of the hollow shaft N4 are respectively inserted or aligned with the openings of the two perforated plates N3, thereby hinging the first arm segment 81a and the third arm segment 81c together.

The hinge shaft passes through the hollow shaft hole of the first hinge 81g, the first transition piece 81e, the second transition piece 81f and the hollow shaft hole of the second hinge 81h in sequence, so that the two support arms are hinged together.

In both the embodiments of fig. 15 and 18, the first transition piece 81e and the second transition piece 81f are connected by connecting members (such as bolts) and the connecting members are hinged by penetrating through the hinged parts on the four arm sections of the X-shaped cross arm, so that the structural stability of the X-shaped cross arm during the lifting process is obviously enhanced

Of course, the structure of the hinge portion is not limited to the two embodiments shown in fig. 15 and 18, and any structure can be used as long as the connection of the two arm sections can be realized and the relative rotation of the two arm sections can be ensured after the connection.
