Description

Technical Field

[0001] The utility model relates to the technical field of automobile modification accessories, in particular to a foldable automobile roof luggage rack which is easy to disassemble and assemble. Background Art

[0002] With the change and improvement of automobile consumption concepts, the single urban commuting function of family cars has gradually developed into a multi-purpose SUV model that integrates urban commuting, suburban travel, long-distance travel, outdoor off-road and other functions. According to data, in recent years, SUV models with the above functions account for the majority of the purchases of family cars in my country. With the popularity of SUVs, a series of automobile products modified around SUV models have also flourished. In this context, roof racks suitable for SUV models for long-distance travel and outdoor travel are favored by consumers. However, in the field of automobile modification products, roof racks still use a bulky fixed installation method. The huge luggage rack covers the top of the vehicle whether it is in use or not. There is a sunroof on the top of the vehicle, and most models currently have panoramic sunroofs. This bulky roof rack is fixedly covered on the entire roof, cannot be moved, and is not easy to disassemble and assemble, so that the sunroof cannot realize functions such as lighting, ventilation, and viewing. At the same time, it also hinders the life-saving function of the sunroof as an emergency exit. The existing roof rack design fails to take into account the flexibility requirements of the vehicle in different usage scenarios. Especially when not in use, the existence of the rack not only affects the appearance of the vehicle, but also increases the wind resistance coefficient of the vehicle, increasing fuel consumption and causing unnecessary waste. Therefore, the market is in urgent need of a new type of roof rack that can meet the needs of carrying when needed and can flexibly adapt to different usage scenarios to reduce the adverse effects on the daily use of the vehicle. The current fixed rack obviously cannot meet these diverse needs. Utility Model Content

[0020] The following combination Figure 1-Figure 5 , the contents of the utility model are described in detail through specific embodiments.

[0021] A foldable car roof luggage rack that is easy to disassemble and assemble comprises a right frame plate 1 and a left frame plate 2 with multiple sections that can be folded on both sides, a front transverse frame body 5, a rear transverse frame body 6, and a plurality of movable cross bars such as a load-bearing cross bar 8 installed between the right frame plate 1 and the left frame plate 2. The right frame plate 1 and the left frame plate 2 have a vertical surface and a horizontal surface. When viewed from the back to the front, the left side is in a ┣ shape, and the right side is in a ┫ shape. The right frame plate 1 and the left frame plate 2 each comprise a front section frame plate, a middle section frame plate and a rear section frame plate, and the section frame plates on both sides are connected on the vertical surface by hinges 7 and hinges 7-1 respectively. The horizontal surface and the vertical surface of the middle section frame plates on both sides are connected by 90° flip hinges 3-2 and 90° flip hinges 4-2 respectively, and the horizontal surface can be rotated and positioned within a range of 90° up and down. The left and right ends of the front section frame plates on both sides and the front transverse frame body 5 are fixedly connected; the left and right ends of the rear section frame plates on both sides and the rear transverse frame body 6 are connected. The movable load-bearing crossbar 8 and other crossbars are arranged on the inner horizontal surface between the right frame plate 1 and the left frame plate 2, and are in an H shape when viewed from the back to the front, and in an eye shape when viewed from the top to the bottom. The vertical surfaces of the front section frame plates and the rear section frame plates on both sides are provided with upper and lower buckle holes, a total of six, for inserting buckles 12 to fix the luggage rack on the original vehicle roof longitudinal bars.

[0022] When the roof luggage rack needs to be installed, the right frame plate 1 and the left frame plate 2 of the folded luggage rack are pulled outward; at this time, since the front transverse frame 5, the rear transverse frame 6, the movable load-bearing cross bar 8 and other cross bars are all designed with three-stage cavity insertion, under the action of tension, the front transverse frame 5 and the rear transverse frame 6 inserted into each other, as well as the movable load-bearing cross bar 8 and other cross bars are pulled out, and the width of the luggage rack is expanded. Then pull out the six U-shaped buckles 12 on the right frame plate 1 and the left frame plate 2, and lift the luggage rack onto the rear of the roof longitudinal bar. Since the U-shaped buckle 12 is a unequal length card plate structure with a long upper part and a short lower part, the luggage rack is supported on the original vehicle roof longitudinal bar by six long cards. Push each U-shaped buckle 12 further into each buckle hole on the frame plate, and the short card plate at the bottom of the buckle is clamped into the original vehicle longitudinal bar. On the front section frame plates on both sides of the luggage rack, directly insert the plug plate 12-1 into the plug plate hole 12-2 of the U-shaped buckle 12 to fix the front ends of both sides of the luggage rack; on the rear section frame plates on both sides of the luggage rack, pass the plug plate 12-1 through the rear section transverse opening 3-1 and the rear section transverse opening 4-1, and insert it into the plug plate hole 12-2 of the U-shaped buckle 12; in this way, the six front and rear U-shaped buckles fix the luggage rack to the original vehicle longitudinal rod, and the luggage rack is installed.

[0023] When the luggage rack needs to be unfolded, the insert plate 12-1 on the U-shaped buckle 12 on the right front section frame plate 1-1 and the left front section frame plate 2-1 is pulled out, and the U-shaped buckles 12 on the left and right front sections are pulled out to make the front transverse frame 5 in a non-fixed state. The front transverse frame 5 is pulled toward the front of the vehicle. Under the action of the pulling force, the right front section frame plate 1-1 and the left front section frame plate 2-1 connected to the front transverse frame 5 are stressed. Under the action of a series of foldings such as the folding 7 and the folding 7-1, the right frame plate 1 and the left frame plate 2 are gradually unfolded until the front transverse frame 5 is pulled to the limit position. At this time, the right frame plate 1 and the left frame plate 2 are pulled into a straight line and fully unfolded. Then push the U-shaped buckles 12 on the right front section frame plate 1-1 and the left front section frame plate 2-1 into the front right frame plate buckle holes 10 and the front left frame plate buckle holes 11, and insert the insert plate 12-1 into the buckle insert plate hole 12-2, so that the right frame plate 1 and the left frame plate 2 are fixed on the roof longitudinal rod. Then press down the erected right middle section frame plate transverse surface 3 and the left middle section frame plate transverse surface 4, and make them flat under the action of the flip positioning hinge 3-2 and the flip positioning hinge 4-2. The first movable cross bar 8 folded between the rear frame plates is pulled toward the front of the vehicle. Since the movable cross bar 8 and other cross bars are connected by connecting rods 9 and other connecting rods, and connected to the transverse T-shaped slide groove 3-4 by T-shaped pulleys 3-3, the other movable cross bars are pulled one by one under the action of the connecting rods 9 and other series of connecting rods, until the movable cross bar 8 is pulled to the predetermined position and stops, and the other movable cross bars also stop synchronously and reach the predetermined position. The fixing pins 8-3 and 8-4 are inserted into the two ends of the first movable cross bar 8, and the first movable cross bar 8 is fixed on the left and right side frame plate transverse planes. At this time, since the movable cross bar 8 is fixed, the other movable cross bars connected thereto are also fixed at the same time under the constraint of the connecting rod 9, and the luggage rack is unfolded and fixed as a whole.

[0024] When the luggage rack needs to be folded, the fixing pins 8-3 and 8-4 on both sides of the front movable load-bearing crossbar 8 are pulled out. At this time, the movable load-bearing crossbar 8 is in a free state. The movable load-bearing crossbar 8 is pushed toward the rear end of the luggage rack. Since the movable load-bearing crossbar 8 and other movable crossbars are connected by connecting rods such as connecting rods 9, and the connecting rod 9 is a two-section hinged limit type, under the action of thrust, the two sections of the connecting rod 9 are folded together until the movable load-bearing crossbar 8 is folded to contact the adjacent movable crossbar, so that the movable load-bearing crossbar 8 pushes the adjacent crossbars to move backward together. And so on, until all the movable load-bearing crossbars are pushed to the rear horizontal frame 6 and reach the limit position, the movable load-bearing crossbar 8 and several other crossbars are folded. Then lift the right middle section frame plate transverse surface 3 and the left middle section frame plate transverse surface 4 upward by 90 degrees to leave folding space, pull out the buckle plug plate 12-1 on the left and right front section frame plates 1-1 and 2-1 of the luggage rack, and pull out the U-shaped buckle 12. At this time, the front end of the luggage rack is in a free state; then push the front transverse frame 5 backward, and the left and right frame plates 2 and 1 of the luggage rack connected to the front transverse frame 5 are stressed, and start to fold under the action of the series of folds such as the folding leaf 7 and the folding leaf 7-1; until the front transverse frame 5 is pushed to the limit position, the folding is completed. Then push the U-shaped buckle 12 on the left and right front section frame plates into the buckle hole 10 on the right front section frame plate 1-1 and the buckle hole 11 on the left front section frame plate 2-1, clamp the roof longitudinal rod, and directly insert the plug plate 12-1 into the plug plate hole 12-2. In this way, the luggage rack is folded as a whole and fixed on the roof.

[0025] When disassembly is required, the plug plates 12-1 on all six U-shaped buckles 12 on the front and rear section frame plates on the left and right sides are pulled out, and the U-shaped buckle 12 is pulled out. Due to the unequal length structure of the upper and lower clamps of the U-shaped buckle 12, at this time, the lower clamp (short) of the U-shaped buckle 12 is separated from the original vehicle longitudinal rod, and the upper clamp (long) of the U-shaped buckle 12 is still supported on the original vehicle roof longitudinal rod. At this time, since the luggage rack is in a folded state and the volume has been reduced, the luggage rack can be conveniently lifted upward to make all the upper clamps of the U-shaped buckle 12 separate from the longitudinal rod, and then the luggage rack is translated backward, so that the luggage rack is disassembled from the longitudinal rod. The disassembled luggage rack is laid flat, and the two sides of the luggage rack are pushed inward. Since the movable load-bearing cross bars 8 and other cross bars on both sides of the luggage rack, the front transverse frame 5 and the rear transverse frame 6 are all three-stage cavity insertion structures, which can be telescopically moved, the luggage rack is completed under the action of thrust. The inward contraction makes the overall luggage rack further reduced.

[0026] Working principle of the utility model

[0027] A foldable car roof luggage rack that is easy to disassemble and assemble. The luggage rack can be folded backward and unfolded forward by means of a hinge 7 on the right frame plate 1 of the luggage rack and a hinge 7-1 on the left frame plate 2. The three-section cavity design of the front transverse frame 5 and the rear transverse frame 6 and the movable load-bearing cross bar 8 therebetween is adopted. The three sections are inserted into each other and can move relatively, so that the luggage rack can be retracted or released left and right. The unequal length structure of the U-shaped buckle 12 and the plug plate setting make the connection and fixation between the luggage rack and the original car roof longitudinal bar simple and firm.

[0028] The utility model realizes the initiative of personal choice in the use state and non-use state through the unfolding and folding of the luggage rack and the convenience of snap-on installation. Through folding and folding, reasonable design and simplification of the structure, and the use of aluminum alloy material, the roof luggage rack is miniaturized, lightweight, and easy to carry and install. It solves and improves the problems of automobile roof luggage rack being bulky and heavy, increasing wind resistance, blocking the skylight, being difficult to carry, and being difficult to disassemble and assemble. It is characterized by: convenient use, increased beauty, reduced fuel consumption, and cost savings.
