AI Technical Summary
It is difficult to easily load and drop equipment for existing roof racks, especially larger equipment or tools, such as ladders, which require frequent load and drop of the roof for picking and placing, which is inconvenient to operate.
A roof equipment is designed to load and exit the vehicle. By installing two fixed frames and a flip frame on the roof, the deformed structure of the four-link mechanism is used to realize the lateral flip of the flip frame, so that the equipment can easily load and exit the vehicle roof.
It realizes that the operator can easily pick up and place the roof equipment under the vehicle, improves the convenience of the equipment and the operation safety of the equipment. At the same time, the buffer rod slows down the descent speed during the flip process, ensuring the stability of the cargo.

[0005] In order to solve the above technical problems, the roof equipment getting on and off device provided by the utility model includes: two fixing frames symmetrically fixedly installed on the top of the vehicle body, the same flip frame is placed on the top of the two fixing frames, the same rotating shaft is rotatably installed on the two fixing frames, two first connecting rods are rotatably sleeved on the rotating shaft, the two first connecting rods are hinged to the flip frame, one end of the second connecting rod is hinged to the fixing frame, the other end of the second connecting rod is hinged to the flip frame, and one end of the rotating shaft is hinged to a rocker.
[0006] Preferably, the flip frame is provided with a self-locking buckle, and the flip frame fixes the goods through the self-locking bag opening.
[0007] Preferably, a clamp is fixedly mounted on the flip frame, and the clamp is matched with the rocker.
[0008] Preferably, a positioning pin is provided on the fixing frame, and two positioning plates are symmetrically fixedly installed on the flip frame, and the positioning pin is matched with the positioning plates.
[0009] Preferably, two buffer rods are rotatably mounted on the outer side of the rotating shaft, and the output shafts of the buffer rods are connected to the fixing frame.
[0010] Compared with the related art, the vehicle roof equipment getting on and off device provided by the utility model has the following beneficial effects:
[0011] The utility model provides a vehicle roof equipment loading and unloading device, which can be flipped sideways: the utility model utilizes the deformation structure of a four-link mechanism composed of two first links and two fifth links to realize the lateral flipping of the flip frame, thereby realizing the action of loading and unloading goods on the vehicle roof;
[0012] Rollover slow descent: When the utility model rolls over with goods, when it turns to the other side away from the center of gravity, there will be a dangerous situation of rapid descent because there is no support at the bottom. The speed of descent can be slowed down by adding a buffer bar. When the buffer bar works synchronously, the rollover frame and the goods can be slowly lowered;
[0013] The flip frame can be quickly locked and unlocked: In order to prevent the device from vibrating and becoming unstable during driving, a locking device needs to be added to the flip frame part, and the positioning pin and positioning piece structure are used to achieve quick locking and unlocking, which is convenient for operation;
[0014] Quick fixation and removal of goods (ladders): In order to make it more convenient and quick for customers to remove / fix goods (ladders), the self-locking buckle structure is used to fix the goods (ladders).

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of the vehicle roof equipment getting on and off device provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure from another perspective is shown; Figure 3 for Figure 1 The schematic diagram of the structure installed behind the roof is shown; Figure 4 for Figure 1 The schematic diagram of the structure of the overturning frame after it is unfolded is shown; Figure 5 for Figure 4 The schematic diagram of the structure after being installed on the roof is shown. The vehicle roof equipment getting on and off device comprises: two fixing frames 1 symmetrically fixedly installed on the top of the vehicle body 10, a same flip frame 2 is placed on the top of the two fixing frames 1, a same rotating shaft 3 is rotatably installed on the two fixing frames 1, two first connecting rods 4 are rotatably sleeved on the rotating shaft 3, both of the two first connecting rods 4 are hinged to the flip frame 2, one end of the second connecting rod 5 is hinged to the fixing frame 1, the other end of the second connecting rod 5 is hinged to the flip frame 2, and a rocker 7 is hinged to one end of the rotating shaft 3.
[0023] The flip frame 2 is provided with a self-locking buckle 8, and the flip frame 2 fixes the goods 9 through the self-locking bag opening 8. Figure 3 and Figure 5 As shown, in this embodiment, the cargo 9 is a ladder.
[0024] A clamp 11 is fixedly mounted on the flip frame 2 , and the clamp 11 is matched with the rocker 7 .
[0025] The fixing frame 1 is provided with a positioning pin 13 , and two positioning pieces 12 are symmetrically fixedly mounted on the flip frame 2 , and the positioning pin 13 is matched with the positioning pieces 12 .
[0026] Two buffer rods 6 are rotatably mounted on the outer side of the rotating shaft 3 , and the output shafts of the buffer rods 6 are connected to the fixing frame 1 .
[0027] The working principle of the vehicle top equipment getting on and off device provided by the utility model is as follows:
[0028] When the roof equipment is to be taken, the operator first releases the positioning pin 13 at the rear of the roof (i.e., pulls the positioning pin 13 out of the positioning piece 12), then pulls out the rocker 7 in the clamp 11, rotates the remote sensor 7 horizontally 90 degrees, and then pushes the rocker 7 downward to rotate it. At this time, the flip frame 2 in the upper part of the mechanism will flip sideways. When it flips to the lowest position, the equipment fixed on the flip frame 2 will also move to the side of the vehicle body 10, and the height is within the range that the operator can manually take, so that the equipment can be easily taken; when placing the equipment, the operation is just the opposite.
[0029] Compared with the related art, the vehicle roof equipment getting on and off device provided by the utility model has the following beneficial effects:
[0030] Can be flipped sideways: The utility model utilizes the deformation structure of the four-link mechanism composed of two first links 4 and two fifth links 5 to realize the lateral flipping of the flip frame 2, thereby realizing the action of putting goods on and off the roof;
[0031] Rollover slow descent: In the process of rolling over with the cargo 9, when the utility model rolls over to the other side away from the center of gravity, there will be a dangerous situation of rapid descent because there is no support at the bottom. The speed of descent is slowed down by adding a buffer rod 6. When the buffer rod 6 works synchronously, the rollover frame 2 and the cargo 9 can be slowly descended;
[0032] The flip frame 2 can be quickly locked and unlocked: In order to prevent the device from vibrating and becoming unstable during driving, a locking device needs to be added to the flip frame 2, and the positioning pin 13 and the positioning piece 12 structure are used to achieve quick locking and unlocking, which is convenient for operation;
[0033] Quick fixation and disassembly of the goods 9 (ladder): In order to make it more convenient and quick for customers to disassemble / fix the goods 9 (ladder), a self-locking buckle structure is used to fix the goods 9 (ladder). Customers only need to simply operate the self-locking buckle 8 to easily fix and disassemble the goods 9 (ladder).
