Domestic passenger car with daily commute and double-function of sojourn and sojourn

Technical Field

The invention relates to a household passenger vehicle with dual functions of daily family commuting and traveling, in particular to a deformable sleeping cabin or a storage cabin which is independently arranged or combined with a carriage to be arranged and can be unfolded and condensed, wherein the deformable sleeping cabin or the storage cabin is connected with the carriage to provide sleeping or storage space, and the household passenger vehicle takes a plurality of household daily commuting vehicles such as large and medium SUVs, MPVs and the like as a basic chassis vehicle. In addition, the liftable deformation type design can be carried out on part or all of the carriages, the heightening and the expansion of the inner space of the carriage are further realized, in addition, the seat layout in the carriage is properly adjusted, and the simple sojourn facilities are configured, so that the household daily commuting vehicle can be immediately converted into a more comfortable compact motor home, passengers can enter the toilet and sleep in an emergency in the driving state, and the dual-purpose vehicle is realized. Namely, the multifunctional automobile can be switched between the daily mode and the motor home mode in time through simple and convenient operation and adjustment, and is more suitable for and meets the requirements of colorful family automobile life.

It should be noted that the "daily commute" and "daily mode" referred to herein refer to a vehicle-using situation in which a person or a family generally travels and lives as a means of commuting instead of walking, so that the two-purpose vehicle is a so-called "dual function" of the vehicle of the present invention, as compared with an unusual vehicle such as a trip.

Technical Field

In the current passenger car market, even in the car types suitable for daily commuting use of families, such as large and medium-sized SUVs, station wagons and MPVs, the requirements of convenience and economy in daily use are considered primarily, and the height of the space in a compartment is basically designed by sitting posture, so that the height of the space in the compartment required by standing and moving of passengers cannot be reached. And according to the life needs, the rear part of the carriage is also provided with a loading space, so that the manned seat can only be arranged in a narrow area in the middle of the carriage, and passengers are bound on the seat to keep sitting posture and cannot move for a long time, which is a very tired thing, and is the normal state of the household daily commuter vehicle. However, for the modern families, with the increase of outdoor leisure and long-distance travel activities, the demand of people for riding comfort is higher and higher, and for this reason, some families purchase motor homes. However, for many households, especially young households, the rate of use of the motor home is not high, and the motor home is often idle for a long time and occupies a floor space and a parking space. The high and big traditional motor home is not easy for old people to drive out and maintain, which is one of the important reasons that some families do not purchase the motor home.

Observing the market discovery, along with the socioeconomic development, the family is daily comfortable, the cross-border trend of car gradually becomes, and some motorcycle types that have the function of touring simultaneously receive more and more favour. For example, a common MPV vehicle type which utilizes tarpaulin to enclose and heighten the vehicle roof has a field sleeping function, has simple structural change, only raises the vehicle roof, but expands the function, better solves the urgent need of field resting and sleeping, and can be said to be a representative of the cross-border development of household vehicles. However, as is known, in most of these types of vehicles, a raised compartment is enclosed by a tarpaulin so that the vehicle can be raised and bedridden only when parked, which in fact functions as a camping tent or a sleeping roof tent. Through searching published publications, the vehicle model that the household daily commuter vehicle has the function of travel and residence is not found by heightening and expanding the space in the compartment in a mode that the additionally-arranged deformation type hard board box bin is communicated and connected with the compartment, and the precedent of using the vehicle model in a public mode is not found.

Detailed Description

Fig. 1 to 20 illustrate a preferred embodiment of the present invention. The basic structure of the vehicle is as follows: the large and medium-sized SUV or MPV is used as a chassis vehicle, the electric lifting design is carried out on most carriage top covers except the top of the front row of seats, and the inner sides of the top covers are provided with four heightening coamings for heightening the carriage; the flat forehead sleeping cabin with an expandable and foldable composite structure is arranged in the middle of the upper part of the car roof, and is moved forwards to the forehead part of the car roof to be expanded and communicated with the heightened carriage when in use, so that the heightening and the expansion of the original carriage are realized; the position and direction of the middle and rear row seats are adjustable, and a simple tourism facility is configured, so that the original household daily vehicle is changed into a compact motor home with a forehead sleeping compartment. The operations of loading, unloading, moving, unfolding, condensing, joining, positioning and the like of the sleeping cabin are carried out by using a special lifting frame. Fig. 1 and 2 are top views of the vehicle in two states of use, daily commuting and travel. The chassis vehicle has the same structure as a common vehicle, and the following description focuses on the structure of the compartment elevation and sleeping compartment of the vehicle and the corresponding operation.

The electric lifting device for heightening the carriage and the roof is described as follows:

as shown in figures 3 and 4, the middle rear part of the carriage top cover is a lifting part 1, four

coamings

2, 3, 4 and 5, namely a front coamings, a rear coamings, a left coamings and a right coamings, are symmetrically stacked on the inner side of the top cover 1, are respectively connected with the top cover 1 along an edge shaft, and can be horizontally attached on the inner side of the top cover 1 and can be turned over downwards to stand. The front and the back enclosing plates 2 and 3 are horizontally stacked close to the inner surface of the top cover 1, and the left and the right enclosing plates 4 and 5 are stacked on the outer layers of the enclosing plates 2 and 3. After the top cover 1 is lifted, the

coamings

5, 4, 3 and 2 are turned downwards and erected in sequence, and then the four-side opening of the lifted top cover 1 can be blocked. The

boarding

2, 3, 4, 5 is turned up and down manually, when in actual use, the car roof 1 is lifted, then the left boarding 4 and the right boarding 5 are turned down to be in close connection with the side edge of the opening, and then the back boarding 3 is turned down to be in close connection with the back edge of the opening and simultaneously lap the left boarding 4 and the right boarding 5. The dash panel 2 is temporarily fixed, and is used as a door panel of the sleeper compartment 30 after the operation of unfolding and butting the sleeper compartment 30 in fig. 6 described below at the front part of the roof is completed. The roof is shown in perspective in fig. 4.

The lifting of the roof 1 is performed by using four groups of electric lifting devices symmetrically arranged at the left edge and the right edge of the top end of the carriage, the four groups of electric lifting devices have the same structure, as shown in fig. 4 and 5, and the roof is seen in perspective in fig. 5. A screw gear 22 is arranged on a rotating shaft 21 of a motor 20 arranged on the inner wall of a carriage and is meshed with a sector balance wheel 23 at the bottom end of an arm rod 6, the sector balance wheel 23 is welded on the arm rod 6 by a diameter edge, a supporting shaft 24 is arranged at the center of the diameter edge and is used for being arranged in a horizontal groove 25 arranged on a vehicle body, and the sector balance wheel can rotate by taking 24 as a shaft. The top of arm lever 6 is connected with the joint 10 of balladeur train 9 through minor axis 8 and carries out the hub connection, square slide 11 of balladeur train 9 then the card cover is in the spout 12 that sets up on car roof 1 bottom surface, motor 20 drives arm lever 6 through the rotation of screw gear 22 like this and uses back shaft 24 to swing as the axle is from top to bottom in the vertical plane, 6 tops of arm lever then drive whole slide frame 9 and do the front and back and slide in the spout 12 of top cap 1, under four group electric lift device synchronization, top cap 1 level change, accomplish top cap 1's lift operation. When the car roof 1 reaches the highest position, the arm lever 6 is erected outside the heightened enclosing plates 4 and 5; when the roof panel 1 is lowered to its original position, the arm lever 6 is laid down in the horizontal grooves 12 formed in both sides of the roof. It is to be noted here that the operation of raising the roof panel 1 must be performed when the sleeper compartment 30 is out of the upper side thereof. The four groups of lifting devices are controlled by the switch buttons of the same group of circuits arranged in the vehicle, so that the safety synchronization is ensured.

In this embodiment, the whole car roof may be designed to be lifted, so that the forehead sleeping box 30 is further moved forward, and thus the two support bars 7 on the car roof need to be extended forward, and may be designed to be telescopic or foldable. In addition, the method for heightening the carriage and the method for blocking the periphery after the top cover of the carriage is raised are obviously diversified, for example, a metal roller shutter, an additionally-arranged combined plate and the like can be used for blocking, and manual operation can be upgraded to electric control. The implementation of the above-described variations is not complicated and will not be described in detail here.

The structure of the sleeping chamber is explained as follows:

as shown in fig. 6, the sleeping box (30) is a flat box in a condensed state, and structurally comprises an inner half-box (31) and an outer half-box (32) which are sleeved together, and each half-box (31, 32) is formed by buckling two shell plates (33, 34, 35, 36) which are symmetrical up and down in a male-female mode. Each pair of

shell plates

33, 34 and 35, 36 is connected inside with its

respective folding bracket

37 and 38. The longitudinal sections of the inner and outer half-

silos

31, 32 are both of an inverted U-shape, and fig. 7 is a partial longitudinal sectional view thereof. 31. 32 are sleeved with an inner side and an outer side at a U-shaped opening end, two parallel linear convex rails 39 are respectively sleeved and clamped in groove slideways 40 on the inner surfaces of

shell plates

35 and 36 of the outer half cabin 32 on the outer surfaces of

shell plates

33 and 34 of the inner half cabin 31, so that the whole inner half cabin 31 can slide in and out linearly in a limited range in the outer half cabin 32. The corner part of the lower shell plate 34 is provided with a retaining bolt 42, and the inner half cabin 31 can be fixed in the position of the outer half cabin 32 by screwing the retaining bolt 42. The inner half cabin 31 is provided with a plate box 41 for placing and fixing the various cabin unfolding plates A1, B1, C1, D1, E1, F1, G1, A2, B2, C2, D2, E2, F2 and G2. The above-mentioned unfolding plates are sequentially inserted between the edges of the upper and

lower shell plates

33, 34 and 35, 36 of the inner and outer half-

chambers

31, 32 after the sleeping chamber 30 is unfolded, and are also connected with each other, so as to finally form an unfolded sleeping chamber, as shown in fig. 6 (e). The four sides of each compartment unfolding plate are of a male-female opening structure, and the sectional view of the compartment unfolding plate is shown in figure 8.

As can be seen from fig. 6, the bottom edges of the

lower panels

34, 36 of the inner and outer half-

compartments

31, 32 each have a notch H1, H2 provided for inserting and engaging the front end of the raised portion of the car. G1 and G2 are two L-shaped sealing plates, the horizontal upper edges of the two L-shaped sealing plates are respectively inserted into the shell plates at the notches H1 and H2, and the lower vertical surfaces of the two L-shaped sealing plates are downward extended and can be connected to a rail rubber strip M arranged at the corresponding position of the roof. Thus, the whole unfolded sleeping compartment 30 is slightly moved backwards, and the upper, lower, left and right sides of the square opening are jointed and bitten with the corresponding plate surface at the front end of the heightened part of the carriage, so that the sleeping compartment 30 is communicated with the carriage in a sealed way.

In a condensed state, in order to make up the gap H2 and seal the outer surface of the sleeping cabin, an L-shaped baffle K is specially configured and used for inserting the lower shell plate 36 at the position H2.

Figure 10 shows the bottom of the sleeper compartment 30 in the collapsed condition, and two sets of parallel double track grooved runners 43, 44 are provided on the outside of the lower shell 36 of the outer half compartment 32 for engagement with the crane slides 80 for smooth loading and unloading of the vehicle. The upper half sections of the two inner slide ways 43 are only provided with bottom grooves but not provided with side grooves, when loading is started, the sleeping box 30 is located at the initial position of the ground, the upper half sections of the two inner slide ways 43 are closely attached to the upper rods L1 of the two slide bars 81 and 82 of the lifting frame, so that the primary positioning of the sleeping box 30 is completed, and the grabbing grooves 46 of the sleeping box 30 are further made to be meshed with the grabbing shovels 85 of the lifting frame slide 80, so that the sleeping box 30 is accurately butted with the lifting frame slide 80; the lower half sections of the two inner slide ways 43 are provided with side grooves, and the upper rods L1 of the two slide bars 81 and 82 are respectively clamped when the sleeping chamber 30 goes upwards. The two outer runners 44 are intended to engage horizontally the elevation rails 67, 68, respectively, of the crane chassis 60 on the roof, see the description below.

The inner half cabin 31 is only provided with two short inner slideways 45, which correspond to the lower half sections of the two inner slideways 43 on the outer half cabin 32 in the ascending process of the sleeping cabin 30, and the upper rods of the slide bars 81 and 82 of the lifting frame are also clamped to play a role in controlling the inner half cabin 31. A cross-sectional view of each runner is shown in figure 9.

The sleeping berth 30 is provided with a grabbing groove 46, a towing handle 47, an opening and closing handle 48, an unfolding handle 49, sealing latches 50 and 51 and a stand 52 at corresponding positions outside the sleeping berth 30, and the sleeping berth 30 can be towed, assembled, disassembled, unfolded and folded.

In addition, the sleeping chamber 30 of this case provides a camp bed function, and can be easily detached from the roof of the vehicle for use as a floor bed in camping, and for this purpose, retractable chamber legs 53 are provided on the bottom surface of the sleeping chamber 30. The opening and closing handle 48 can also be used to hang the slide 80. In addition, a camping tent is also arranged, so that a small outdoor house with an upper bed and a lower bed can be built, and the camping tent is interesting and has a figure 11.

In this embodiment, the position where the sleeper compartment 30 is unfolded and engaged with the vehicle compartment can be theoretically set at different positions of the vehicle roof or the vehicle compartment, even behind the side car, but the arrangement on the forehead of the vehicle compartment is most reasonable. In addition, the forehead sleeping compartment can be made small and exquisite, the sleeping compartment does not provide a sleeping function any more, and the storage compartment is only used for placing luggage articles to replace the storage function of the rear space in the original carriage, so that the inner space of the whole original carriage is a space for passengers to take and move. By adjusting the seat layout in real time and raising the roof, the riding comfort of the compact motor home can be provided. Meanwhile, the seat is designed into a composite structure which can be unfolded and combined into a bed, so that the sleeping function in the vehicle can be provided, and the outdoor urgent need can be met. Compared with a forehead sleeping cabin type vehicle, the forehead storage cabin type vehicle is smaller, lighter and more practical. It is not difficult to imagine that the composite structure and the materials of the storage bin are varied no matter the storage bin is a sleeping bin or a more compact storage bin, the optimal implementation mode only shows the principle by a simple manual opening and multi-plate assembly type structure, and actually, by applying modern technological means, the varied automatic and intelligent variable type storage bin with high level can be obviously designed.

The structure of the crane is explained below:

as shown in fig. 12, a special lifting frame is provided for lifting, placing, positioning, front-back left-right moving of the forehead sleeping box 30. The structure of the slide is divided into two parts, namely a bottom frame 60 and a slide 80, which are connected through a front supporting tube 101 and a rear supporting tube 102. The chassis 60 is a cross-shaped structure formed by connecting a front parallel cross bar 61 and a rear parallel cross bar 62 through two longitudinal connecting rods 63 and 64. The front bar 61 is fixedly connected with the two connecting rods 63 and 64, and the rear bar 62 is connected with the two connecting rods 63 and 64 by using the dismounting bolts 65 and 66 for mounting and dismounting the slide 80. Both bars 61, 62 are attached from the outer ends with a length of parallel elevated rails 67, 68 for abutting and penetrating the outer slide 44 of the sleeper compartment 30 to slide and secure the sleeper compartment 30 thereon. The two connecting rods 63 and 64 are connected by a standard rod 69 at the central part, and the rod 69 can support the step rods T1, T2, T3 and T4 of the slide 80 which is inserted into the underframe 60 from the left side, so that the step rods cannot fall down to touch the top surface of the vehicle, and the slide 80 can be ensured to slide in smoothly. At the same time, the standard rod 69, together with the two support tubes 101, 102, positions the slide 80 in the horizontal position when it enters the chassis 60, ensuring that the two outer slide ways 44 of the sleeping accommodation 30 on the slide 80 smoothly abut against and slide into the two upper rails 67, 68 of the chassis 60.

The whole lifting frame is mounted on the roof of the vehicle and can slide back and forth along the roof by sleeving the four end heads 71, 72, 73 and 74 of the two cross bars 61 and 62 of the underframe 60 on the two support bars 7 of the vehicle roof. Tightening the positioning bolt 793 positions the under frame 60 on the roof support bar 7.

The main ends 71, 73 of the two bars 61, 62 are special members having the function of coupling the slide 80 and making it turn up and down. Fig. 13 is a sectional view of the main end 71 of the front bar 61 coupled to the support pipe 101. An opening 751 at the lower end of the support post 75 is arranged on the roof support bar 7 in a riding mode, and a shaft hole 752 is formed at the upper end of the support post 75 and used for inserting the support tube short shaft 103. In addition, a downwardly inclined retainer plate 78 is attached to the outside of the main head 71 for resting on a slide 80. The stopper plate 79 of the main end 73 of the rear cross bar 62 is larger, and a slide lock hole 791, a key hole 792, and a chassis positioning bolt 793 are provided.

The slide 80 is used for loading and unloading the vehicle with the sleeping box 30. The structure of the ladder is formed by connecting two identical parallel sliding bars 81 and 82 through five ladder step rods T1, T2, T3, T4 and T5. The two sliding bars 81 and 82 are of a connected upper and lower double-bar structure, the lower bar L2 is used for connecting the support tubes 101 and 102, and is respectively sleeved in the grooves of the support tubes 101 and 102 and slides along the grooves; the upper bar L1 provides a sliding track for the sleeping chamber 30, and the sliding tracks respectively penetrate into the two inner slideways 43 of the sleeping chamber 30.

The ladder step rods are provided with foot pedals, so that the slide can be used as a ladder for people to go up and down the roof and go up and down a sleeping room during camping in the open air. The two ladder step rods T3 and T4 in the middle are arranged at the middle concave part position where the upper and lower rods L1 and L2 of the two sliding bars are connected, and do not obstruct the normal sliding of the upper and lower rods L1 and L2. The other three T1, T2 and T5 are not directly connected to lower rod L2, so that supporting tubes 101 and 102 sleeved on lower rod L2 cannot pass through, thereby limiting the sliding range of slide 80 along supporting tubes 101 and 102.

The bottom of the slide is provided with a locking tongue 83 for being inserted into a locking hole 791 on the limiting plate 79 on the bottom frame 60 to lock the slide 80 on the bottom frame 60. The lock hole 792 can be opened by inserting a key.

A manual elevator device is embedded in the slide 80, and mainly comprises a slide bar 84, a grab shovel 85 and a pull wire 86 thereof, an upper pulley 87, a lower pulley 88, a rocking shaft 89, a clutch 90, a rocker arm 94 and the like.

Fig. 14 shows a detailed structure of the bottom of the slide 80, in perspective view of the step bar T5 for easy viewing. The rocker shaft 89 with the lower pulley 88 is inserted into the hollow ladder step bar T5 to rotate, and the lower pulley 88 divides the T5 into left and right parts. The clutch 90 is composed of a circular fixed plate 91, a movable plate 92 and a push plate spring 93, the fixed plate 91 is fixedly connected to the outer end of the step bar T5, the rocker shaft 89 penetrates through the circle centers of the fixed plate 91 and the movable plate 92 to be connected to a rocker arm 94, and the two plates 91 and 92 are controlled to be in clutch through a hand brake 95 on the rocker arm 94. The structure principle is as follows: the two disks 91 and 92 are passed through the center of the shaft 89, but the fixed disk 91 is fixed on the step bar T5, and the movable disk 92 can slide left and right within the limited range of the shaft 89, but can not rotate around the shaft 89, because the axial sliding groove on the surface of the shaft 89 controls the posture of the movable disk 92. At ordinary times, the movable disc 92 is pushed by a disc pushing spring 93 sleeved on the rocking shaft 89 and is attached to the fixed disc 91, and under the action of friction force between the fixed disc and the fixed disc, the fixed disc and the fixed disc are kept relatively static, the rocking shaft 89 and the rocker arm 94 can not rotate, and the state is an 'closed' state; when the hand brake 95 on the rocker arm 94 is clenched, the movable disc 92 is pulled through the brake cable 96 to move backward against the resistance of the spring 93, and leaves the fixed disc 91, so that the movable disc 92 and the rocking shaft 89 become rotatable, which is in an off state, and the rocking shaft 89 and the lower pulley 88 are rotated by rotating the rocker arm 94, so that the grasping shovel 85 is pulled through closing the pull wire 86, and the grasping shovel 85 is engaged with the grasping groove 46 on the sleeping box 30, and finally the whole sleeping box 30 is driven to slide on the slide 80.

The supporting tubes 101 and 102 are large semicircular sections, and the openings of the supporting tubes are outwards sleeved on the lower rods L2 of the sliding bars 81 and 82 of the slide 80 respectively so as to enable the supporting tubes to slide under the control of the supporting tubes; the

short shafts

103 and 104 arranged in the middle of the outer side surfaces of the supporting tubes 101 and 102 are respectively inserted into the shaft holes 752 and 762 at the upper parts of the supporting

columns

75 and 76 of the main ends 71 and 73 of the cross bars of the underframe, so that the slide 80 can slide under the control of the supporting tubes 101 and 102, and can also be turned over up and down by taking the

short shafts

103 and 104 of the supporting tubes as shafts.

When the slide 80 needs to be detached from the base frame 60, the detaching bolts 65 and 66 are loosened, and the rear bar 62 is moved slightly rearward, so that the

short shafts

103 and 104 of the support pipes 101 and 102 can be disengaged from the shaft holes 752 and 762 of the

support columns

75 and 76, respectively.
