Description

Technical Field

[0001] The utility model relates to a car sunshade, in particular to a novel car sunshade. Background Art

[0002] At present, the utilization rate of cars in my country is getting higher and higher. When the car is parked under the scorching sun, the metal plate of the car body can quickly accumulate heat, causing the temperature in the car compartment to rise rapidly. After driving, a large amount of energy is needed to cool down. Therefore, the application of automobile sunshade devices has been widely promoted. At present, automobile sunshade devices on the market are mainly divided into two types: manual opening and closing and electric opening and closing. For example, the applicant has previously disclosed an invention patent entitled: A framework of an automobile awning (publication number: CN101890898B), which includes a chassis, a transmission shaft, a rollover shaft, and a rollover rod fixed on the rollover shaft; the chassis is also provided with a front baffle rotating with the transmission shaft and a pair of driven shafts arranged on the front baffle, and the driven shaft is provided with a side baffle support rod, and the motor can drive the transmission shaft, the front baffle, the rollover shaft and the driven shaft to rotate synchronously. The sunshade cloth can be folded with the flipping of the rollover rod and the side baffle support rod, which overcomes the defect that the sunshade cloth at the corners in the prior art is difficult to be folded and folded, saves the trouble of manual intervention, and is easy to be automatically controlled.

[0003] However, in actual use, the applicant found that when the invention is folded, the driven shaft drives the side baffle support rod to flip inward, and at the same time, the front baffle frame also flips synchronously with the transmission shaft. When the angle between the front baffle frame and the chassis begins to be less than 90°, the distance between the side baffle support rod and the chassis is the smallest, and interference is likely to occur; the same problem will occur when the invention is unfolded. In order to avoid mutual interference, the length of the side baffle support rod can only be shortened, but this will significantly reduce the sunshade area of ​​the invention. In order to ensure sufficient shading area, the material of the side baffle support rod is glass fiber in the actual production process of the invention, so that even if interference occurs, it can pass through the interference area through its own deformation. However, excessive deformation of the glass fiber will also cause it to break, so the length of the side baffle support rod will still be limited, and the reaction force caused by the deformation of the glass fiber will also cause the sunshade cloth in the interference area to be easily broken, and will also cause the rotation resistance of the motor to be too large, burning the motor. Summary of the invention

[0004] The utility model provides a novel automobile sunshade awning, which solves the problems in the prior art that the sunshade area is limited and the frame is easy to interfere with the base or the sunshade cloth.

[0005] The above technical problems of the utility model are mainly solved by the following technical solutions: a novel automobile awning, comprising a base, a first flip shaft horizontally rotatably arranged on the front and rear sides of the base, a flip seat fixed relative to the first flip shaft, a second flip shaft horizontally rotatably arranged on the left and right sides of the base, a first rib fixed on the second flip shaft, a third flip shaft rotatably arranged on the left and right sides of the flip seat, a second rib connected to the third flip shaft, and a motor fixed on the base, the output shaft of the motor being transmission connected with all the flip shafts, characterized in that: a shaft sleeve is provided on the fixed sleeve of the third flip shaft, the shaft sleeve cannot rotate relative to the third flip shaft, a steering sleeve is rotatably provided on the shaft sleeve, the rotation axis of the steering sleeve is perpendicular to the third flip shaft, the second rib is fixedly inserted on the steering sleeve, an elastic member is provided between the steering sleeve and the shaft sleeve that can maintain the second rib in a state perpendicular to the third flip shaft, and the first rib and the second rib are covered with sunshade cloth.

[0006] The motor of the utility model serves as a common power source for the first flip axis, the second flip axis and the third flip axis. When the motor is started, the first flip axis, the second flip axis and the third flip axis will rotate synchronously, thereby driving the flip seat, the first rib and the second rib to flip synchronously, thereby realizing the unfolding or folding of the sunshade cloth. When the utility model rotates to the interference angle, the end of the second rib will contact the base and the sunshade cloth, and the reaction force will be transmitted to the steering sleeve. At this time, the elastic member is deformed by force to realize the deflection of the steering sleeve, so that the angle of the second rib will change adaptively, so that it can pass through the interference angle relatively easily, so that the pressure on the second rib, the base and the sunshade cloth is small, and the resistance to the motor is also small. Since the steering sleeve can be deflected at a large angle, the length of the second rib can also be made longer, effectively improving the sunshade surface of the utility model.

[0007] Furthermore, the flip seat is also provided with two fourth flip shafts connected to the third flip shafts and a fifth flip shaft connected to the two fourth flip shafts, and the fourth flip shafts and the fifth flip shafts are both fixed with deformable frames, and the deformable frames are also covered with sunshade cloth. The third flip shaft, the fourth flip shaft and the fifth flip shaft are linked to each other, and the linkage can be achieved through a coupling or a bevel gear structure, so that the deformable frame and the second umbrella rib can be turned synchronously, so that the sunshade area of ​​the utility model can be larger and the sunshade effect is better.

[0008] Furthermore, the deformable frame includes a first link hinged to the flip seat, a second link fixed to the fourth flip axis or the fifth flip axis, a third link, and a third rib fixed to the third link. The two ends of the third link are respectively connected to the first link and the second link for rotation. The three links and the flip seat form a trapezoidal four-bar linkage. When the second link rotates with the fourth flip axis or the fifth flip axis, the third link will flip synchronously and drive the third rib to flip. In the fully folded state, the three links and the third rib are folded within the coverage of the flip seat. Such a structural design is also to ensure that the deformable frame can be folded and folded by the flip seat, and to increase the unfolded length of the deformable frame as much as possible, thereby increasing the sunshade area.

[0009] Therefore, compared with the prior art, the utility model has the following characteristics: 1. When the utility model is rotated to the interference angle, the end of the second rib will contact the base and the sunshade cloth. At this time, the elastic part is deformed by force to realize the deflection of the steering sleeve, so that the angle of the second rib will change adaptively, so that it is relatively easy to pass through the interference angle, so that the pressure on the second rib, the base and the sunshade cloth is relatively small, and the resistance to the motor is also relatively small; 2. Since the steering sleeve can be deflected at a large angle, the length of the second rib can also be made longer, effectively improving the sunshade surface of the utility model.

[0019] The single motor of this embodiment can be used as a common power source for a single first flip shaft, a single second flip shaft and two third flip shafts. When the motor is started, the first flip shaft, the second flip shaft and the third flip shaft will rotate synchronously, thereby driving the flip seat, the first rib and the second rib to flip synchronously, thereby realizing the unfolding or folding of the sunshade. When this embodiment rotates to the interference angle, the end of the second rib will contact the base and the sunshade, and the reaction force will be transmitted to the steering sleeve. At this time, the elastic member is deformed by force to realize the deflection of the steering sleeve, so that the angle of the second rib will change adaptively, so that it can pass through the interference angle relatively easily, so that the pressure on the second rib, the base and the sunshade is relatively small, and the resistance to the motor is also relatively small. Since the steering sleeve can be deflected at a large angle, the length of the second rib can also be made longer, effectively increasing the sunshade surface of this embodiment.

[0020] See Figure 1The flip seat is also provided with two fourth flip shafts 40 connected to the third flip shaft in transmission, and a fifth flip shaft 50 connected to the two fourth flip shafts in transmission. The fourth flip shaft and the fifth flip shaft are both fixed with a deformable frame 60, and the deformable frame is also covered with a sunshade cloth. The third flip shaft, the fourth flip shaft and the fifth flip shaft are linked to each other, and the linkage can be realized through a coupling or a bevel gear structure, so that the deformable frame and the second umbrella rib can be turned synchronously, so that the sunshade area of ​​this embodiment can be larger and the sunshade effect is better.

[0021] See Figure 5 and Figure 6 The deformable frame includes a first link 61 hinged to the flip seat, a second link 62 fixed to the fourth flip axis or the fifth flip axis, a third link 63, and a third rib 64 fixed to the third link. The two ends of the third link are respectively connected to the first link and the second link. The three links and the flip seat form a trapezoidal four-link mechanism. When the second link rotates with the fourth flip axis or the fifth flip axis, the third link will flip synchronously and drive the third rib to flip. In the fully folded state, the three links and the third rib are folded within the coverage of the flip seat. Such a structural design is also to ensure that the deformable frame can be folded and folded by the flip seat, and to increase the unfolded length of the deformable frame as much as possible, thereby increasing the sunshade area.

[0022] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
