Abstract
Description
[Technical Field]
[0001] The present invention relates to a roof tent for a vehicle. [Background technology]
[0002] Conventionally, as a mechanism for opening and closing the roof of an automobile, Patent Document 1 discloses opening and closing links provided on the left and right sides of the opening and closing roof, left and right cylinders with one end rotatably provided near the opening and closing rotation center axis of the opening and closing roof and the other end provided on the opening and closing folding axis of the opening and closing link, and a tent with both ends attached to the opening and closing end sides of the opening and closing roof and to the roof body.
[0003] This disclosure states that an air compressor draws air from an air tank, and supplies the drawn air to an air cylinder via a cord to operate the retractable roof. It also discloses that the retractable roof is made of FRP resin material. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-341366 Summary of the Invention [Problem to be solved by the invention]
[0005] Conventional vehicle bodies are often made of steel to ensure rigidity. In vehicles with steel bodies and roof tents, an opening is made in the center of the steel roof of the vehicle, and a roof body made of fiber-reinforced plastic such as FRP or CFRP is installed.
[0006] In such vehicles with roof tents, the outer wall of the body around the roof opening, which is made of steel, and the outer wall of the roof main body, which is made of fiber-reinforced resin, are made of different materials. Therefore, the overall appearance of the vehicle body is aesthetically different from the impression it leaves on the viewer. Users dislike the sense of incongruity caused by the properties of different materials between the body and roof main body, and have been demanding a vehicle with a roof tent that has a uniform, integrated feel.
[0007] Conventional roof bodies made of fiber-reinforced resins have difficulty in reducing the weight of the roof body because they must maintain a certain level of strength. Furthermore, roof bodies made of FRP have problems such as the surface roughness of the exterior walls becoming rough, resulting in relatively low rigidity, and light reflected by the exterior walls of the roof body creating a wavy reflection pattern on the surface of the roof body, thereby compromising quality.
[0008] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a high-value-added roof tent for use in a vehicle. [Means for solving the problem]
[0009] The vehicle roof tent of the present invention is a vehicle roof tent (6) having a tent that can open and close a hole formed in the roof of a vehicle, a base (4) fixed to a roof edge (7) of a vehicle body (2); a roof body (8) made of a metal material that can open and close the opening (5) of the base; a first link mechanism (30) that connects the roof body to the base so as to be capable of relative movement; The vehicle employs a structure including a tent portion (50) that can be formed on the vehicle exterior side of the opening of the base.
[0010] It has been discovered that various properties can be obtained by making the roof body of a vehicle roof tent out of metal. The aesthetic appearance of the roof body has been highly praised by certain users. Generally, when a vehicle body having a roof tent and the roof main body are constructed from different materials, it is difficult to ensure homogeneity in the characteristics of the vehicle body and the vehicle roof, resulting in a sense of incongruity between the appearance of the entire vehicle and the appearance of the roof main body.
[0011] The vehicle roof tent of the present invention has solved this problem: when the roof body is manufactured from metal material, a high-density outer wall can be formed on the surface of the roof body without any wavy light patterns on the outside. The vehicle roof tent of the present invention maintains the aesthetic appearance of a smooth surface without any wavy irregularities on the vehicle body when irradiated with sunlight or other light, and also maintains the aesthetic appearance of the continuous smooth surface between the outer wall of the roof main body of the roof tent and the outer wall of the vehicle body, maintaining a sense of unity. This ensures a harmonious and homogeneous appearance of the boundary area between the vehicle body and the roof main body in the overall appearance of the vehicle's exterior wall, and throughout the entire vehicle with the roof tent, the vehicle body and the roof main body in the closed state blend together, creating an aesthetic appearance that does not create a sense of incongruity.

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vehicle roof tent according to an embodiment of the present invention will now be described with reference to the accompanying drawings. In the following, substantially identical components in multiple embodiments will be designated by the same reference numerals, and their description will be omitted.
[0014] (First embodiment) A first embodiment of the present invention will be described with reference to FIGS. The body 2 of the vehicle 1 is made of steel and has a roof hole 3 in the roof portion, and the base 4 of the roof tent 6 is fixed to the roof edge 7 that forms this roof hole 3. The roof edge 7 is connected to the front pillar 15. The front pillar 15 forms part of the body. The base 4, roof edge 7 and front pillar 15 are made of steel. The roof edge 7 corresponds to the periphery of the roof main body 8 described in the claims.
[0015] The roof tent 6 is attached to the body 2. Here, the fixed part of the roof tent 6 refers to the base 4 and the like, and the movable part refers to the link mechanism, actuator, roof main body 8 and the like.
[0016] When the tent function of the roof tent 6 is not in use and the roof main body 8 is in a closed state, the link mechanism and actuators as components of the roof tent 6 are stored in the vehicle. The roof edge 7 of the body 2, excluding the roof hole 3, is made of steel and continues to the steel front pillar 15. The surface continuing from the roof edge 7 to the front pillar 15 is smooth and has a continuous texture.
[0017] The base 4 is made of steel and has an opening 5 formed in the center as shown in Figure 2. The base 4 is formed in a rectangular shape with a front edge, side edges, and rear edge, and has the opening 5 formed in the center. The roof body 8 is made of steel, can open and close the opening 5 shown in Figure 2, and is connected to the base 4 via a link mechanism, actuator, etc., which will be described later. The roof body 8, like the front pillars and roof edge, is also made of steel, and forms a smooth surface with no ripples or irregularities that is aesthetically pleasing. The roof body 8 functions as a highly rigid roof for the tent.
[0018] Figures 4 to 8 show the link mechanism of the roof tent. The link mechanism connects the base 4 and the roof body 8 so that the opening 5 can be opened and closed. The link mechanism consists of first link mechanisms 10 arranged on the left and right sides of the front side, and second link mechanisms 30 arranged on the left and right sides of the rear side.
[0019] The first link mechanism 10 consists of an actuator 11 and a lever 14. One end of the lever 14 is rotatably attached to the frame 9 of the roof body 8, and the other end is rotatably attached to the side edge of the base 4. One end of a cylinder 12 of the actuator 11 is connected to a first connecting portion 17, and this first connecting portion 17 is connected to the base 4. The tip of the rod 13 is rotatably attached to the center of the lever 14.
[0020] The second link mechanism 30 is attached to the left and right sides of the vehicle rear side of the first link mechanism 10 at the lateral edges of the base 4. One end of a first lever 31 is rotatably connected to the base 4, and the other end is rotatably connected to one end of a first link 32, and the other end of the first link 32 is rotatably connected to the frame 9 of the roof main body 8. A second link 34 has one end rotatably connected to the base 4, and the other end is rotatably connected to one end of a second lever 33, and the other end is rotatably connected to the frame 9 of the roof main body 8. The center of the first link 32 and the center of the second link 34 are rotatably connected.
[0021] 7 shows the roof body in a closed state, illustrating the relationship between the first connecting portion 17 of the first link mechanism 10 and the fixing portion 18 of the base 4 when the roof body is in a closed state. The locking pin 48 at one end 141 of the lever 14 is fitted into the locking groove 19 of the fixing part 18. The end 461 of the third connecting part 46, which is rotatably attached to the pin 47 at one end 141 of the lever 14, is fixed to the frame 9 attached to the roof body 8. When the roof body 8 is opened, the locking pin 48 of the lever 14 comes out of the locking groove 19 of the base 4 as shown by the dashed line and is released. At this time, in the second connecting portion 23 of the base 4, the pin 24 at the other end 142 of the lever 14 moves the elongated hole 25 of the base 4 to the right in Figure 8, and then the lever 14 rotates clockwise in Figure 8.
[0022] The actuator 11 shown in Figures 4, 5, and 6 has an electric motor (not shown), such as a servo motor, inside a cylinder 12, and a power transmission mechanism (not shown) that receives the driving force of the electric motor and operates in conjunction with it. The power transmission mechanism is composed of, for example, a motor shaft (not shown) of a servo motor (not shown), a screw shaft (not shown) connected to the motor shaft, balls (not shown), a ball screw nut (not shown) that houses the balls, and a rod 12 connected to the end of the nut. The rod 12 is extended or retracted by switching between forward and reverse rotation of the motor shaft. The position of the tip of the rod 12 can be accurately controlled with high output using a small-diameter cylinder.
[0023] As shown in Fig. 10, the control device 61 controls switching between a state in which the tent section 50 is formed on the vehicle roof as shown in Fig. 1 and a state in which the first link mechanism 10 and the second link mechanism 30 are folded to store the tent section 50 in the vehicle. As shown in Fig. 10, the control device 61 includes an open / close switch 60 provided near the driver's seat inside the vehicle cabin, and a control unit 61 that performs calculations in response to the output of the open / close switch. The servo motor (not shown) rotates forward or reverse in response to the output of the control unit 61 after calculation processing, and extends or retracts the rod 12 via the power transmission mechanism (not shown). The roof body 8 is controlled to a desired open / close position via the first link mechanism 10 and second link mechanism 30 (shown in Figs. 4, 5, and 6) that are connected to the extendable rod 12.
[0024] The control unit 61 is activated by the output of the open / close switch 60, and sends a drive signal to the servo motor of the actuator 11 so that the roof body 8 is in the open or closed state corresponding to the operator's intention.
[0025] When the operator turns on the roof open switch using the opening / closing switch 60, the control unit 61 sends a drive signal corresponding to the roof being open to the servo motor, and as the servo motor rotates forward, the drive force is transmitted to the link mechanism via the power transmission mechanism, and the roof continues to operate via the link mechanism until the main body of the roof is in the open state. When the open state is detected, the rotational drive of the servo motor stops. When the operator turns on the roof close switch using the opening / closing switch 60, the control unit 61 sends a drive signal corresponding to the roof being closed to the servo motor, and as the servo motor rotates backward, the drive force is transmitted to the link mechanism via the power transmission mechanism, and the roof continues to operate via the link mechanism until the main body of the roof is in the closed state. When the closed state is detected, the rotational drive of the servo motor stops.
[0026] 1 and 9, when the roof body 8 is in the open state, the tent section 50 is in the open state shown in Fig. 9. When in the open state, the tent section 50 has a tent function. The tent section 50 is made up of rubber bands 52, cloth 56, and mesh 57, 58. The rubber bands 49 are made up of front rubber bands 53 on the left and right sides of the front, a rear rubber band 54, side rubber bands 55 in the vertical direction on the sides, and horizontal rubber bands 52. The fabric 56 is formed on the sides and rear of the tent in a sheet shape. It serves to separate the inside and outside of the tent, thereby preventing the intrusion of rainwater, sunlight, and wind.
[0027] A front mesh 57 (window) is attached between the front rubber bands 53 on both the right and left sides, and a side mesh 58 (window) is attached to the side. The rubber bands, cloth, and mesh 57, 58 that make up the tent section 50 can be detached from the base 4 and roof main body 88 via detachable members such as fasteners (not shown) from the vehicle. The mounting sections that are attached to the base 4 and roof main body 88 and the tent section 50 that can be detached from these mounting sections can be detached by switching between opening and closing fasteners (not shown). The mounting sections are provided on the cloth section 56. The fasteners provided on the cloth section 56 correspond to the detachable members described in the claims.
[0028] When the roof main body 8 shown in FIG. 1 transitions from the open state to the closed state, the tent portion 50 is folded and can be stored inside the passenger compartment of the vehicle 1 at the roof edge 7 of the body 2 in conjunction with the roof main body 8. When the roof main body 8 transitions from a closed state to an open state, the fabric folded into the vehicle interior of the tent portion 50 stretches, and the tent portion transitions to the open state shown in FIGS.
[0029] The front mesh 57 can be attached and detached from the front rubber band 53 with a fastener. When the front mesh 57 is separated from the rubber band with the fastener, a window that completely opens the tent interior space to the inside and outside is formed within the frame formed by the front rubber band 53. When the front mesh 57 is attached to the front rubber band, the front mesh 57 that is partially open to the inside and outside is formed in the area that corresponds to the window.
[0030] The tent section 50, which can be separated from the vehicle, can be replaced with other tent sections with different styles, such as different window positions, sizes, or fabric types. The tent section can be replaced depending on the season. The interchangeable tent section can be easily cleaned or replaced with a different tent section with a different design, enhancing the comfort of living in a tent with a vehicle.
[0031] As described above, in this embodiment, the roof body is made of steel, which has many advantages. For example, if both the vehicle body 2 and the roof main body 8 are made of steel, there is no sense of incongruity between the overall appearance of the vehicle and the roof main body. This improves the aesthetics of the entire vehicle. In particular, when the roof main body 8 is closed or the vehicle is moving, there is no sense of separation between the body 2 and the roof, and the overall vehicle has a unified and integrated aesthetic appearance, which improves the commercial value of a vehicle with a roof tent.
[0032] Next, the results of a characteristic test conducted on the roof body of a vehicle equipped with a roof tent will be described. (1) Characteristic test The steel roof body according to this embodiment was compared with a comparative FRP roof body.
[0033] The FRP roof body in the comparative configuration weighs 42.67 kg and has a volume of 21663 cm 3 , Total area of the top surface: 86974cm 2 , Density: 1970kg / m 3 It was. In contrast, the steel roof body of this embodiment weighs 23.89 kg and has a volume of 3040 cm 3 , Total area of the roof top surface: 86929 cm 2 , Density: 7860kg / m 3 It was.
[0034] In comparison with the comparative example, this embodiment has a similar external shape, but the roof body is thinner. By using steel, the roof body was significantly thinner than the comparative example. The volume of the steel roof body was small, the total area of the top surface of the roof body was approximately the same as the comparative example, the weight was light, and the roof body was high-density.
[0035] Regarding the roof body, when the present embodiment made of steel was compared with a comparative form made of FRP, comparative numerical data (dimensions, plate thickness, material, weight, etc.) was obtained showing that the steel (present embodiment) was able to be made thinner, more dense, lighter, and more rigid.
[0036] According to this embodiment, the roof main body 8 connected to the highly rigid body 2 of the vehicle 1 is made of steel and used as the roof of the tent, so that a tent roof with a highly rigid upper surface can be formed, and a vehicle roof tent with an excellent living space below the roof main body 8 can be formed. According to this embodiment, the weight provided on the vehicle body is relatively light compared to the comparative embodiment, so the fuel efficiency characteristics of the vehicle are excellent. It is possible to provide a vehicle roof tent that is both lightweight and highly rigid.
[0037] According to this embodiment, the tent unit 50 is normally stored inside the body 2 when the tent is not in use, for example, when the vehicle is stopped or traveling normally. When the tent is in use, the tent unit 50 can be automatically assembled on the roof of the vehicle by turning on the opening / closing switch 60. Furthermore, the tent 50 can be folded and stored inside the body (vehicle interior) by turning off the opening / closing switch 60. Therefore, by moving the vehicle to a destination, selecting an appropriate location at the destination, and moving the vehicle to that location, the interior space of the vehicle can be expanded by simple operations inside the driver's cab at that location, creating a comfortable, mobile living space. Because the tent unit is attached to the vehicle body, the workload during transportation to the destination can be reduced.
[0038] (2) Appearance test Comparative experiment 1 (experiment using sunlight) Regarding the appearance of the roof body, a comparative experiment was conducted by irradiating sunlight outdoors on a steel roof body (embodiment 1) and an FRP roof body (comparison form 1).
[0039] In the case of the steel roof body (Embodiment 1), in comparison with Comparative Example 1, the surface was a beautifully finished curved surface that was smooth, glossy, and free of distortion, with no irregularities. The surface of the FRP roof body was a wavy, uneven reflective surface, but in the first embodiment, no wavy reflective surface was observed and the reflective surface was smooth and even.
[0040] In order to explain the degree of visual beauty when evaluating the finished surface when the roof body is made of steel, a schematic image diagram comparing Comparative Example 1 made of FRP with Embodiment 1 made of steel is shown in Figure 11. In Comparative Example 1 shown in Figure 11A, a disturbance 80 in the reflected light of wavy thin lines appears in the area between the roof body 88 and base 84, but in Embodiment 1 shown in Figure 11B, a stable and orderly reflected light 20 appears as straight thin lines 20 extending from the roof body 8 to the base 4 and up to the roof edge 7.
[0041] 11A, in Comparative Form 1, a wavy surface was observed on the surface of the roof main body 88 due to light reflection. In appearance, in Comparative Form 1, the texture of the roof main body 88 and the texture of the roof edge 7 (body) adjacent to the roof main body were heterogeneous.
[0042] In embodiment 1, as shown in Figure 11B, the light-reflecting surface generated on the surface of the roof body is a smooth surface, and the texture is visually perceived to be the same as the reflective surface of the entire vehicle body, including the roof edge 7 surrounding the roof body 8.
[0043] The commercial value of the vehicle roof tent 6 was evaluated as being significantly higher for the steel roof body (embodiment 1). Although evaluations vary depending on tastes and preferences among a wide range of values, it was found that there is at least a high demand for steel roof tents. In this respect, the commercial value of the vehicle roof tent according to this embodiment was evaluated as being high.
[0044] Comparative experiment 2 (experiment using linear fluorescent light) In Comparative Experiment 2, when a linear light was irradiated onto the roof body, the band-like streak shape reflected on the reflective surface of the roof body was compared between a case where the roof body was made of FRP (Comparative Form 2) and a case where the roof body was made of steel (Embodiment 2).
[0045] A comparison was made between Comparative Example 2, an FRP roof body, and Example 2, a steel roof body. A schematic image of the results is shown in Figure 12. As shown in Figures 12A and 12B, the two surfaces that reflect the linear light become strip-like reflective surfaces 81 and 82 with jagged edges in Comparative Example 2, whereas in Embodiment 2 they become smooth, uniformly wide, clearly defined strip-like reflective surfaces 71 and 72, giving the impression of the beauty of a stable, smooth surface.
[0046] Although one embodiment of the present invention has been described as a vehicle roof tent having a steel roof body, the present invention may also be applied to a vehicle roof tent having a roof body made of a material other than steel, for example, a metal or alloy material such as aluminum or an aluminum alloy.
[0047] In the present invention, the metal or alloy material constituting the vehicle body and the metal or alloy material constituting the roof body may be different metal or alloy materials. If a metal or alloy material is used, it is possible to manufacture a roof body having a smooth surface that does not have an uneven or wavy appearance on the outer wall of the roof body, unlike FRP.
[0048] In the embodiment described above, the metal material of the roof body was steel, but the present invention predicts that even if the roof body and the body surrounding the roof body are manufactured from other metal materials, "they will have the same high-quality, commercial value texture in appearance."
[0049] When the roof tent is in the open position, a panel mat (not shown) corresponding to the floor panel member may be supported on the body at a location corresponding to the opening 5 of the base 4, forming a floor device that functions to cover the opening and also functions as a floor. The panel mat may also be separable from the body, or may be a foldable multiple mat, or may be rotatably connected to the roof body. A floor device that forms a floor member separating the driver's cab from the tent interior space may also be installed. When the floor member is laid out, it is possible to sleep on the floor member, making it possible to sleep overnight in the vehicle.
[0050] In the embodiment, a servo motor is used as an example of the electric motor used as the drive source for the actuator, but other types of electric motors may be used in the present invention. A ball screw is used, but other power transmission mechanisms may be used. As for the power transmission mechanism that converts the drive force of the electric motor into the extension and retraction motion of the rod, a power transmission mechanism other than the ball screw used in the above embodiment may be used in the present invention. As a result, compared to drive sources such as air cylinders and hydraulic cylinders, electric motors have the advantages of being smaller in size and allowing the actuator to be installed in a small space, allowing for effective use of the vehicle interior space, producing less noise during operation, and being easy to operate.
[0051] In the above embodiment, the roof is a front-opening type in which the roof body enlarges the opening at the front of the vehicle, but the present invention may also be applied to a rear-opening type embodiment in which the roof body enlarges the opening at the rear of the vehicle.
[0052] In the above embodiment, the roof body is driven to open and close by an actuator, but the present invention may also be directed to an embodiment in which the roof body is driven to open and close by manually operating a spring damper and a link mechanism instead of an electric motor.
[0053] Here, the roof body made of metal and the surrounding body made of metal are said to have the same texture in appearance. They have the same texture in appearance to the extent that the texture of a steel roof body is indistinguishable from the texture of a steel body.
[0054] As described above, the present invention is not limited to the above-described embodiment, and can be implemented in various forms without departing from the spirit and scope of the present invention. [Explanation of symbols]
