Description

Technical Field

[0001] The invention belongs to the field of automobile parts, and in particular relates to a hard flip hood. Background Art

[0002] The cargo bed of a pickup truck (also known as a sedan truck) is used to haul goods. Since the cargo bed of a pickup truck is open, in order to prevent rain from wetting the goods in the cargo bed in rainy and snowy weather, people invented a hood. The hood is installed on the cargo bed of the pickup truck and used to cover the goods in the cargo bed to prevent the goods in the cargo bed from being wetted by rain.

[0003] The existing car hood is erected at 90 degrees, and the support system has a concentrated stress point when supporting, which can easily cause damage to the support system.

[0004] Secondly, most existing car hoods require multiple shafts, but the car hood does not need to be fully opened in actual use. Therefore, if a lower-cost shaft system is used, the frequently rotating shaft system is easily damaged. If a higher-cost shaft system is used, the production cost of the entire car hood will be too high. Summary of the Invention

[0005] The purpose of the present invention is to provide a hood with a multi-axis system. By improving the support system, the support system is made more stable and has a longer service life. Secondly, by utilizing the cost and service life characteristics of different axis systems, the economy of the hood is made more obvious.

[0006] In order to solve the above problems existing in the prior art, the technical solution adopted by the present invention is:

[0007] A hard flip car cover comprises a front barrier system, a first plate body, a second plate body, a third plate body and a supporting system.

[0008] The support system includes a pad, a pad block and a large front fence rotating shaft. The pad is connected to the front of the vehicle, and the pad is connected to the front fence system.

[0009] The first plate body is rotatably connected to the front fence system via a large front fence rotating shaft, and the first plate body is rotatably connected to the second plate body via a first rotating shaft system.

[0010] The second plate body is rotatably connected to the third plate body via a second rotating shaft system.

[0011] The three-point positioning of the first plate is achieved through the large front rail shaft, pad and pad. When the first plate is flipped up, the upper end of the first plate rests on the pad, and the first shaft system is pressed on the pad. At this time, the angle between the plate and the horizontal plane is greater than 90°, so that the plate can stand upright.

[0012] Furthermore, the support system also includes a support rod assembly and a large front fence rotating shaft, the support rod assembly includes a support rod, a support head and a support block, the support head is connected to the plate body through a support base, the support base is arranged parallel to the plate body, the support block includes a fixed part, an inclined plate, a support groove and a transition part, the fixed part is connected to the truck bucket, the inclined plate is connected to the fixed part through the transition part, the inclined plate is inclined 15-25° relative to the fixed part, the inclined plate is provided with a "U"-shaped support groove, the support rod is engaged in the support groove, the large front fence rotating shaft includes a top column and a front fence rotation center, the front fence rotation center is rotatably connected to the top column; the front fence rotation center is connected to the first plate body through a connecting arm, the front fence rotation center is provided with a first limiting part, the top column is arc-shaped, and the top column is provided with a second limiting part adapted to the first limiting part, the large front fence rotating shaft not only drives the first plate body to flip, but also uses its hard connection structure to support the first plate body after rotation. By adjusting the position of the connecting arm, the rotation angle of the large front bar shaft can be controlled, and thus the rotation angle of the first plate body can be controlled. Since the plate body can rotate 95°-110° when rotating, the plate body is not completely vertical after being erected, and forms an obtuse angle of 95°-110° with the cargo box. In this way, the support base can be directly connected to the plate body and set parallel to the plate body, while the existing plate body can only rotate 90°. In this way, the support base needs to make an oblique angle of about 15° when connected to the plate body to facilitate the connection of the support rod. Since the support rod is tilted after the plate body is erected, the tilted plate is tilted 15-25°. After the support rod is connected to the tilted plate, the contact area between the nut and the tilted plate is larger, and the force on the tilted plate is more uniform, which not only makes the support more stable, but also extends the service life of the support block. The pad can be a long strip or a plurality of block-shaped structures arranged in sequence. As long as the plate body can be supported, it will be fine.

[0013] Furthermore, the pad includes a cushioning pad and a fixed pad. The fixed pad is connected to the front hood system, and the cushioning pad is connected to the fixed pad. The cushioning pad has an L-shaped structure and is used to support the plate body. The L-shaped cushioning pad can support the second rotating shaft system and prevent it from sliding. The pad can have only the fixed pad or a cushioning pad attached to the fixed pad. When the hood leaves the factory, the pad only has the fixed pad. Customers can choose the pad according to their actual needs.

[0014] Furthermore, the first rotating shaft system includes a first intermediate rotating rod and two first side rods, the two first side rods are respectively rotatably connected to the first intermediate rotating rod, the first side rod is provided with a side rod mounting slot, the side rod mounting slot is "C"-shaped, and an intermediate mounting slot is respectively provided at both ends of the first intermediate rotating rod, and the intermediate mounting slot is "C"-shaped, and a first connecting strip is respectively connected between the two first side rods and the first intermediate rotating rod, the first connecting strip is made of rubber, the first connecting strip includes a first connecting surface and two first base feet, the two first base feet are connected through the first connecting surface, the two first base feet are respectively located in the side rod mounting slot and the intermediate mounting slot, the first side rod is provided with a side rod protrusion, the side rod protrusion is connected to the notch of the side rod mounting slot, the first intermediate rotating rod is provided with a middle protrusion, the middle protrusion is connected to the notch of the middle mounting slot, the middle protrusion is longer than the side rod protrusion, or the middle protrusion can be shorter than the side rod protrusion, as long as the notch of the side rod mounting slot and the middle mounting slot are not the same size. By providing side bar protrusions in the side bar mounting grooves and intermediate protrusions in the intermediate mounting grooves, and controlling the lengths of the side bar protrusions and the intermediate protrusions, the slot size is reduced. Consequently, after the first foot extends into the side bar mounting grooves and the intermediate mounting grooves, the first foot in the side bar mounting groove can be removed due to the shorter side bar protrusions, while the first foot in the intermediate mounting groove cannot be removed due to the longer intermediate protrusions. Since the first foot can be removed from the side bar mounting grooves, the first connecting strip only serves a waterproofing function and does not serve a connecting function. The first rotating shaft system is still connected by rotation via the first intermediate rotating rod and the front rail rotation center of the first side bar. The first rotating shaft system uses a rubber strip, which reasonably reduces production costs.

[0015] Furthermore, the ends of the first rotating shaft system are connected to a left end cover, a right end cover and an intermediate end cover, the left end cover and the right end cover are respectively connected to the two first side bars by screws, the intermediate end cover is connected to the first intermediate rotating rod by screws, the left end cover is provided with a left end cover top panel, the right end cover is provided with a right end cover top panel, and the intermediate end cover is provided with an intermediate end cover top panel, and the left end cover top panel, the right end cover top panel and the intermediate end cover top panel are all arranged on the upper side of the first connecting surface. The first connecting strip is a "π"-shaped structure, and the first base is connected to the first connecting surface by a connecting piece. The size of the first base is larger than the size of the connecting piece, and the connecting piece is slightly smaller than the notch of the intermediate mounting groove. The first connecting strip is designed as a "π"-shaped structure, which can have good stability and good waterproof effect after connection; and the first connecting strip is arranged on the upper side of the rotation center of the front rail of the first rotating shaft system. When the first rotating shaft system rotates, the first connecting strip will not be subjected to tension, thereby avoiding damage to the first connecting strip caused by long-term rotation.

[0016] Furthermore, the hinge system includes a second hinge system, the second hinge system includes a second intermediate hinge rod and two second side rods, the two second side rods are respectively rotatably connected to the second intermediate hinge rod, the second side rod is provided with a side rod mounting slot, the second intermediate hinge rod is provided with two intermediate mounting slots, a second connecting bar is connected between the second side rod and the second intermediate hinge rod, the second connecting bar includes a second connecting surface and two mounting portions, the second connecting surface is made of leather or other non-elastic flexible material, the two mounting portions are connected by the second connecting surface, each mounting portion is respectively connected to a second foot, the two second feet are respectively located in the side rod mounting slot and the intermediate mounting slot, the second hinge system designs the second connecting bar as a split structure, the second connecting surface is connected to the mounting portion by glue during installation, and the second foot is also snapped into the profile during use, and since the second connecting surface is made of plastic material, its service life is longer. Since the second hinge system needs to be opened each time it is opened, the second hinge system is made of plastic material, which greatly extends the service life of the second hinge system and reduces the cost of use.

[0017] Furthermore, the mounting portion includes a clamping plate, a connecting portion and a supporting portion, the upper side of the supporting portion is connected to the connecting portion, the upper side of the connecting portion is connected to the clamping plate, an insertion port is provided between the clamping plate and the supporting portion, and insertion ends are provided at both ends of the second connecting surface, the insertion ends extend into the insertion port, and the two insertion ports are arranged opposite to each other.

[0018] Furthermore, the hood also includes a guide rail, a clip system, and a lock system. The guide rail is connected to the truck bed via the clip system. The lock system includes a lock tongue cylindrical head and a lock tongue. The lock tongue is connected to the hood. The lock tongue cylindrical head is connected to the truck bed or the guide rail via the clip system. Each plate body is provided with a corresponding lock system. Each lock system includes two lock tongues and two lock tongue cylindrical heads. The two lock tongue cylindrical heads are respectively connected to both sides of the truck bed. The two lock tongues are respectively connected to both sides of the plate body and correspond to the lock tongue cylindrical heads. The two lock tongues are connected by a wire rope, and the wire rope is connected to a handle. By pulling the handle, the lock system can be quickly opened, making it convenient to open the hood. In addition, when closing the hood, it is only necessary to press down on the plate body.

[0019] The beneficial effects of the present invention are as follows:

[0020] The present invention adopts a new supporting system and uses three-point positioning to support the upright vehicle cover, thereby ensuring the stability of the vehicle cover and extending the service life of the supporting system.

[0021] The present invention adopts two different rotating shaft systems, so that the rotating shaft system of the hood that rotates frequently has a longer service life, and the rotating shaft system that rotates infrequently has a lower production cost, making the economy of the hood more obvious.

DETAILED DESCRIPTION

[0044] The present invention will be further described below with reference to the accompanying drawings and accompanying drawings.

[0045] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0048] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0049] Example 1:

[0050] like Figure 1 、 4 As shown in Figures 18 and 19, a hard flip cover includes a front barrier system, a first plate 5, a second plate 6, a third plate 7 and a support system.

[0051] The support system includes a pad 85, a pad block 84 and a large front fence shaft 1. The pad 85 is connected to the vehicle head 9, and the pad block 84 is connected to the front fence system.

[0052] The first plate body 5 is rotatably connected to the front fence system via the large front fence rotating shaft 1 , and the first plate body 5 is rotatably connected to the second plate body 6 via the first rotating shaft system 2 .

[0053] The second plate body 6 is rotatably connected to the third plate body 7 via the second rotating shaft system 3 .

[0054] The three-point positioning of the first plate body 5 is achieved through the large front rail shaft 1, the pad 84 and the pad 85. When the first plate body 5 is flipped up, the upper end of the first plate body 5 rests on the pad 85, and the first shaft system 2 is pressed on the pad 84. At this time, the angle between the plate body and the horizontal plane is greater than 90°, so that the plate body can stand upright.

[0055] Example 2:

[0056] On the basis of Example 1, Figure 15-17 As shown in , 20 and 21, the support system also includes a support rod assembly and a large front fence shaft 1.

[0057] The support rod assembly includes a support rod 81 , a support head 82 and a support block 83 .

[0058] The support head 82 is connected to the plate body through the support base 86, and the support base 86 is arranged parallel to the plate body. The support block 83 includes a fixed part 831, an inclined plate 832, a support groove 833 and a transition part 834. The fixed part 831 is connected to the truck bed, and the inclined plate 832 is connected to the fixed part 831 through the transition part 834. The inclined plate 832 is inclined 15-25° relative to the fixed part 831. The inclined plate 832 is provided with a "U"-shaped support groove 833, and the support rod 81 is engaged with the support groove 833.

[0059] The large front fence rotation shaft 1 includes a top column 11 and a front fence rotation center 12, and the front fence rotation center 12 is rotationally connected to the top column 11; the front fence rotation center 12 is connected to the first plate body 5 through a connecting arm 13, and the front fence rotation center is provided with a first limiting portion 14, the top column 11 is arc-shaped, and the top column 11 is provided with a second limiting portion 15 adapted to the first limiting portion 14.

[0060] The large front fence rotating shaft 1 not only drives the first plate body 5 to turn over, but also supports the rotated first plate body 5 by utilizing its hard connection structure.

[0061] When the hood is closed, the first plate 5 is in a horizontal state, and the second limiting portion 15 presses against the first limiting portion 14 and limits the first limiting portion 14; when the hood is opened, the first plate 5 is in an upright state, and the connecting arm 13 rests against the end of the top column 11, and the top column 11 supports the front rail rotation center 12.

[0062] By adjusting the position of the connecting arm 13 , the rotation angle of the large front fence shaft 1 can be controlled, thereby controlling the rotation angle of the first plate body 5 .

[0063] Since the plate body can rotate 95°-110° when rotating, the plate body is not completely vertical after being erected, and forms an obtuse angle of 95°-110° with the cargo box, so that the support base 86 can be directly connected to the plate body and set parallel to the plate body, while the existing plate body can only rotate 90°, so the support base 86 needs to make an oblique angle of about 15° when connected to the plate body to facilitate the connection of the support rod 81.

[0064] In actual use, it is necessary to connect a nut (not shown) to the support rod 81 and use the nut to press on the inclined plate 832 to provide supporting force.

[0065] Since the support rod 81 is an inclined support after the plate body is erected, the inclined plate 832 is tilted 15-25°. After the support rod 81 is connected to the inclined plate 832, the contact area between the nut and the inclined plate 832 is larger, and the force on the inclined plate 832 is more uniform, which not only makes the support more stable, but also extends the service life of the support block 83.

[0066] The pad 85 can be in the form of a strip or a plurality of blocks arranged in sequence, as long as the plate body can be supported.

[0067] When the board is flipped and folded, the third board 7 is located between the first board 5 and the second board 6. One of the second side bars 31 of the second hinge system 3 rests on the cushion 841. At the same time, the first board 5 is close to the pad 85. Then, the support rod 81 is connected to the support block 83. The support of the support rod 81 makes the board more stable after standing upright and prevents the board from shaking. After the board is stood upright, one of the second side bars 31 of the second hinge system 3 presses on the pad 84, and the second middle connecting bar 33 and the other second side bar 31 of the second hinge system 3 are suspended in the air.

[0068] The pad block 84 includes a buffer pad 841 and a fixed pad 842. The fixed pad 842 is connected to the front rail system. The fixed pad 842 is provided with a socket 843. The buffer pad 841 is connected to the fixed pad 842. The buffer pad 841 is an "L"-shaped structure. The buffer pad 841 is used to support the plate body. Making the buffer pad 841 into an "L"-shaped structure can support the second rotating shaft system 3 to prevent it from sliding.

[0069] The pad 84 may have only the fixed pad 842 or the buffer pad 841 may be connected to the fixed pad 842. When the hood leaves the factory, the pad 84 has only the fixed pad 842. Customers can choose the pad according to their actual needs.

[0070] Example 3:

[0071] On the basis of Example 2, Figure 5-8As shown, the first rotating shaft system 2 includes a first intermediate rotating rod 21 and two first side rods 23, and the two first side rods 23 are respectively rotatably connected to the first intermediate rotating rod 21 (the two first side rods 23 are respectively rotated 95°-110° around the first intermediate rod), and the first side rod 23 is provided with a side rod mounting groove 2302, and the side rod mounting groove 2302 is "C"-shaped. An intermediate mounting groove 2101 is respectively provided at both ends of the first intermediate rotating rod 21, and the intermediate mounting groove 2101 is "C"-shaped (the "C"-shaped structure not only makes the first connecting strip 24 stable, but also can adjust the size of the slot, thereby controlling the tightness of the connecting strip and the side rod or intermediate rod). A first connecting strip 24 is respectively connected between the two first side rods 23 and the first intermediate rotating rod 21, and the first connecting strip 24 Made of rubber, the first connecting strip 24 includes a first connecting surface 2403 and two first bases 2401. The two first bases 2401 are connected by the first connecting surface 2403. The two first bases 2401 are respectively located in the side bar mounting groove 2302 and the middle mounting groove 2101. The first side bar 23 is provided with a side bar protrusion 2301, and the side bar protrusion 2301 is connected to the notch of the side bar mounting groove 2302. The first middle rotating rod 21 is provided with a middle protrusion 2102, and the middle protrusion 2102 is connected to the notch of the middle mounting groove 2101. The middle protrusion 2102 is longer than the side bar protrusion 2301, or the middle protrusion 2102 is shorter than the side bar protrusion 2301, as long as the notches of the side bar mounting groove 2302 and the middle mounting groove 2101 are not the same size.

[0072] By setting a side bar protrusion 2301 in the side bar mounting groove 2302 and a middle protrusion 2102 in the middle mounting groove 2101, and controlling the length of the side bar protrusion 2301 and the middle protrusion 2102, the size of the slot is reduced. In this way, after the first base foot 2401 is inserted into the side bar mounting groove 2302 and the middle mounting groove 2101, since the side bar protrusion 2301 is shorter, the first base foot 2401 in the side bar mounting groove 2302 can be taken out, while the middle protrusion 2102 is longer and the first base foot 2401 in the middle mounting groove 2101 cannot be taken out.

[0073] Since the first base 2401 can be removed from the side bar mounting groove 2302, the first connecting strip 24 only plays a waterproof role and does not play a connecting role. The connection of the first rotating shaft system 2 is still achieved through the rotation center of the front railing of the first intermediate rotating rod 21 and the first side bar 23. The first rotating shaft system 2 uses a rubber strip, which reasonably reduces the production cost.

[0074] The ends of the first rotating shaft system 2 are connected with a left end cover 26, a right end cover 27 and an intermediate end cover 28. The left end cover 26 and the right end cover 27 are respectively connected to the two first side rods 23 by screws, and the intermediate end cover 28 is connected to the first intermediate rotating rod 21 by screws. The left end cover 26 is provided with a left end cover top panel 2601, the right end cover 27 is provided with a right end cover top panel 2701, and the intermediate end cover 28 is provided with an intermediate end cover top panel 2801. The left end cover top panel 2601, the right end cover top panel 2701 and the intermediate end cover top panel 2801 are all provided on the upper side of the first connecting surface 2403.

[0075] The first connecting strip 24 is a "π"-shaped structure, and the first base 2401 is connected to the first connecting surface 2403 through a connecting piece (not shown in the figure). The size of the first base 2401 is larger than that of the connecting piece, and the connecting piece is slightly smaller than the notch of the middle mounting groove 2101.

[0076] The first connecting bar 24 is designed as a "π"-shaped structure, which has good stability and good waterproof effect after connection; and the first connecting bar 24 is set on the upper side of the rotation center of the front bar of the first rotating shaft system 2. When the first rotating shaft system 2 rotates, the first connecting bar 24 will not be subjected to tension, avoiding damage to the first connecting bar 24 caused by long-term rotation.

[0077] Example 4:

[0078] On the basis of Example 1, Figure 9-12 As shown, the shaft system includes a second shaft system 3, the second shaft system 3 includes a second intermediate shaft and two second side rods 31, the two second side rods 31 are respectively rotatably connected to the second intermediate shaft, the second side rod 31 is provided with a side rod mounting groove 2302, the second intermediate shaft is provided with two intermediate mounting grooves 2101, a second connecting bar 25 is connected between the second side rod 31 and the second intermediate shaft, the second connecting bar 25 includes a second connecting surface 252 and two mounting portions 251, the second connecting surface 252 is leather or other Non-elastic flexible material (the second connecting strip 25 is a split structure, the two mounting parts 251 are made of plastic, the middle second connecting surface 252 has no elasticity, but can be bent and deformed. When connecting, the second connecting surface 252 is glued or sewn to the two mounting parts 251 to ensure the tightness of the connection), the two mounting parts 251 are connected through the second connecting surface 252, and each mounting part 251 is respectively connected to a second base foot 2513, and the two second base feet 2513 are respectively located in the side rod mounting groove 2302 and the middle mounting groove 2101.

[0079] The second rotating shaft system 3 designs the second connecting bar 25 as a split structure. During installation, the second connecting surface 252 is connected to the mounting portion 251 by glue. When in use, the second base 2513 is also inserted into the profile. Since the second connecting surface 252 is made of plastic material, its service life is longer.

[0080] Since the second rotating shaft system 3 needs to be opened each time the device is opened, the second rotating shaft system 3 is made of plastic material, which greatly prolongs the service life of the second rotating shaft system 3 and reduces the cost of use.

[0081] Example 5:

[0082] On the basis of Example 4, Figure 13-14 As shown, the mounting portion 251 includes a clamping plate 2511, a connecting portion 2512 and a supporting portion 2514. The upper side of the supporting portion 2514 is connected to the connecting portion 2512, and the upper side of the connecting portion 2512 is connected to the clamping plate 2511. An insertion port 2515 is provided between the clamping plate 2511 and the supporting portion 2514. Insertion ends 2521 are provided at both ends of the second connecting surface 252, and the insertion ends 2521 extend into the insertion port 2515.

[0083] The two insertion ports 2515 are arranged opposite to each other.
