Detailed Description

The invention is further illustrated by the following figures and examples in conjunction with the description:

as can be seen from fig. 2, 5 and 11, the mobile bidirectional expandable house includes: a main body frame 1 supported on the ground and having at least one set of slide rails 11 symmetrically disposed at side edges thereof; at least one expansion frame 2, which is arranged on the slide rail 11 in a sliding manner; the first driving mechanism 3 drives the expansion frame to slide in or out of the main body frame, so that the expansion frame 2 is positioned in the main body frame or suspended on the side edge of the main body frame, and when the expansion frame 2 is suspended on the side edge of the main body frame 1, the main body frame 1 is communicated with the inside of the expansion frame 2 to form an internal space of a movable house; a floor member 4 corresponding to the extension frame, one side of which is hinged to a lower portion of the main body frame; the second driving mechanism 5 is connected with the floor piece, and the floor piece is overturned under the driving of the second driving mechanism 5 so as to be attached to one vertical side surface of the main body frame 1 or the bottom of the expansion frame; and a shielding film mechanism 7, wherein the shielding film mechanism 7 comprises a rotating shaft (not shown in the figure) rotatably arranged at the upper part of the main body frame and a shielding film 71 connected to the rotating shaft, and the shielding film 71 covers the outer side of the house main body or is wound on the rotating shaft.

The invention utilizes the shielding film mechanism 7 to adjust the lighting degree of the mobile house, meets the lighting degree requirement and simultaneously can utilize the shielding film mechanism to form an air heat insulation layer on the outer side of the mobile building.

as shown in fig. 12 and 13, the masking film mechanism 7 further includes a storage box 72, a push rod 73 and a driving motor (not shown in the drawings), the storage box 72 is longitudinally disposed on the top of the main frame, the rotating shaft is rotatably disposed in the storage box 72, the driving motor is drivingly connected to the rotating shaft, and one end of the push rod is hinged to the outer side surface of the expansion frame; when the expansion frame 2 extends out of the main body frame, the shielding film extends to the lower part of the outer side of the expansion frame from the side opening of the storage box, and the other end of the ejector rod 73 abuts against the middle of the shielding film, so that the shielding film covers the outer side of the house main body, and the part of the shielding film above the expansion frame is trapezoidal, so that the rainproof and windproof functions are better.

In order to ensure that the state of the ejector rod can be fixed when the expansion frame is positioned in the main body frame, the mobile house frame is further optimized as follows: the upper portion lateral surface of main body frame 1 is provided with the joint portion 74 corresponding with the ejector pin, and when expanding the frame and removing inside the main body frame, the upper portion joint of ejector pin is in joint portion 74. The clamping portion 74 is an annular member provided with an opening on a side facing the stem, and is made of an elastic material.

When the driving motor rotates forwards, the shielding film is released from the storage box and extends downwards to the outer side of the expansion frame under the action of gravity; when the driving motor rotates reversely, the main part of the shielding film is stored in the storage box, and the edge of the shielding film can be provided with a limiting block so that the edge is finally connected to the end part of the ejector rod to facilitate the next unfolding; of course, the shielding film may be completely accommodated in the storage case.

As can be seen from fig. 2 and 3, there are two sets of slide rails 11, and the two sets of slide rails are parallel to each other; correspondingly, there are two expansion frames 2, namely a first expansion frame 21 and a second expansion frame 22; the first expansion frame and the second expansion frame can respectively slide on the two sets of slide rails 11 of the main body frame along mutually opposite directions. By the implementation mode, when the two expansion frames extend to two sides of the main body frame, torsion generated by the expansion frames relative to the main body frame can be balanced to a certain degree, so that the overall structure is more stable; and because the first expansion frame is longer than and higher than the second expansion frame, the invention can obtain larger internal space in the use state under the condition of not increasing the structural size of the main body frame.

Of course, the combination relationship between the extended frame, the first driving mechanism, the floor member and the second driving mechanism is not limited to the aforementioned preferred manner, for example, an extended frame and a fixed display unit are arranged on the main frame in a reverse sliding manner, the extended frame is provided with the floor member and the corresponding second driving mechanism, the fixed display unit is driven by the first driving mechanism, a form that the floor member is fixedly arranged at the bottom of the extended frame is also feasible, and the extended frame and the fixed display unit can play a role in mutual balance.

As can be seen from fig. 5, the outer side surface of the floor member 4 is connected with a link mechanism 401; the second driving mechanism 5 is a second oil cylinder connected to the lower portion of the main body frame, and an output end of the second oil cylinder is connected to the link mechanism 401 to drive the floor member to turn around the lower portion of the main body frame.

As shown in fig. 2 and 4, the main body frame 1, the first expansion frame 21, and the second expansion frame 22 are all rectangular frames, and the two sets of slide rails 11 are respectively arranged on the inner sides of the two longitudinal ends of the main body frame along the transverse direction; the first expander frame 21 is longer and higher than the second expander frame 22; and the transverse two side surfaces of the main body frame are respectively provided with a first sealing frame and a second sealing frame which are in contact connection with the upper parts of the first expansion frame and the second expansion frame.

The expansion frame arranged on the main body frame in a sliding mode is used for carrying out space expansion, the operation is simple and convenient, the space expansion efficiency is high, the turnover type floor piece is used for laying the floor, and the floor fall between the main body space and the expansion space is effectively avoided. By arranging the first sealing frame and the second sealing frame between the expansion frame and the main body frame, the space is quickly expanded, and meanwhile, a connecting gap between the moving parts is avoided.

As can be seen from fig. 2 and 6, a doorway leading from the outside to the internal space is provided on one side surface of the main body frame 1, and a doorway side of the main body frame is hinged to a doorway member 6. The lower edge of the porch piece 6 is hinged with the lower edge of the entrance; the outer side of the porch member is connected to the lower portion of the body frame by a pair of spring rods 61.

One side of the main body frame is connected with a control unit, and the control unit is in signal connection with the first driving mechanism 3 and the second driving mechanism 5. The main body frame 1 is provided with a stroke detection unit 8 for detecting the stroke of the expansion frame, the stroke detection unit 8 is positioned on one side of the slide rail, and a plurality of detection points are distributed along the sliding direction of the expansion frame, and the detection points respectively detect the moving speed of the expansion frame and transmit detection signals to the control unit.

As can be seen from fig. 7 and 8, the stroke detection unit 8 includes a detection cylinder 81 and a plurality of micro generators (not labeled in the figure), the detection cylinder 81 is disposed at one side of the guide rail, and a plurality of holes (not labeled in the figure) are disposed on a side wall of the detection cylinder; the microgenerators are arranged in the detection cylinder at equal intervals (or at any interval) to form detection points, the input end of the microgenerators is connected with a friction wheel 82, and the edge of the friction wheel is in contact with the expansion frame through the hole; the output end of the micro generator is in signal connection with the control unit. When the first expansion frame extends outwards from the inside of the main body frame, all the friction wheels of all the corresponding micro generators rotate under the action of the friction force of the first expansion frame, so that all the micro generators corresponding to the first expansion frame generate electricity; when the output electric quantity of the first micro generator in the direction opposite to the moving direction of the first expansion frame is 0, the first expansion frame can be judged to slide by the stroke corresponding to the first micro generator, and the like, so that the stroke of the first expansion frame can be monitored in real time, and the overturning process of the corresponding floor piece can be started under the condition that the first expansion frame slides out enough stroke so as to ensure that the corresponding floor piece cannot be in rigid collision with the first expansion frame.

And because the oil cylinder driving mechanism usually has the common problems of the oil cylinder, such as the piston rod does not move due to insufficient oil cylinder pressure, the oil cylinder pressure is sufficient but the piston rod still does not move, the driving speed does not reach the specified value, and the like, the invention is usually used in the scene which is far away from the modern industrial civilization and has better natural scenery, so that once the problems occur, the invention is difficult to maintain in time. The problem of the oil cylinder is a gradual process, and the oil cylinder can be maintained in advance through the working performance before serious problems occur, so that the situation is avoided.

In view of this, the control unit of the present invention may draw a time-speed curve graph during the movement of the expansion unit according to the electric quantity output by the micro-generator, when the present invention is shipped and used, the first driving mechanism is in an optimal movement state, the time-speed curve graph at this time is used as a standard graph, the time-speed curve graph after the present invention is put into use is compared with the standard graph, and when the deviation between the two is large, it may be determined that the working state of the first driving mechanism is abnormal, so as to actively maintain the first driving mechanism.

Similarly, the stroke detection unit may also adopt other common structures, such as a pressure-sensitive or capacitive stroke switch, however, the processing method of the position information is still the aforementioned processing method, and the above technical effects can also be obtained, but in consideration of the use environment of the present invention, the present invention preferably selects such a stroke detection unit with a stable detection state as shown in fig. 7 and fig. 8.

Referring to fig. 2 and 9, at least three supporting legs 9 are disposed at the lower portion of the main frame 1, two electronic levels (not labeled in fig. 9) disposed horizontally and longitudinally are connected to the main frame, and the electronic levels are connected to the control unit; the supporting feet 9 are supporting oil hydraulic cylinders, the cylinder portions 901 of the supporting oil hydraulic cylinders are supported on the ground, and the corresponding piston rods 902 are connected with the main body frame; the control unit is in signal connection with the supporting legs.

Specifically, four supporting feet 9 are provided, and are distributed on the lower parts of the longitudinal two ends of the main body frame in a pairwise symmetrical manner; the upper part of the support leg is connected to the main body frame to be horizontally movable by the driving of the corresponding horizontal telescopic cylinder 91.

The main body frame 1 is composed of a plurality of hollow components with channels inside; the internal channel of the hollow component can be used as an air-conditioning air circuit and even a water and electricity pipeline, so that the whole structure is more attractive while the space is further saved.

One side of the porch member 6 is provided with a step member 62. The details of the step part 62 are shown in fig. 10, the step part 62 is composed of a plurality of step plates 621, two sets of support rods 622, parallel rods 623 and adjusting rods 624, one ends of the two support rods 622 are symmetrically hinged to the side edge of the porch part, and the other ends of the two support rods 622 are supported on the ground; two ends of one side of the step plate 621 are equidistantly connected to the inner sides of the two support rods, two ends of the other side of the step plate are equidistantly connected to the parallel rods, and the step plates are parallel to each other and the parallel rods 623 are parallelly arranged below the support rods; the lower end of the adjusting rod 624 is hinged with the middle of the parallel rod, the middle of the adjusting rod 624 is connected with the middle of the supporting rod in a longitudinally movable manner, specifically, the middle of the adjusting rod 624 runs through the adjusting hole in the middle of the supporting rod, and the adjusting rod is provided with threads in the middle and matched with an adjusting nut, so that the adjusting rod can be adjusted according to the actual height of the main body frame, and the actual use requirement can be better met.
