Description

Technical Field

[0001] The utility model relates to the technical field of vehicle auxiliary components, in particular to an anti-skid mechanism for a car tail plate. Background Art

[0002] The car lifting tailgate is generally set at the rear of the car body. It can not only close the tailgate of the car body by folding the tailgate, but also raise and lower the platform by lifting the tailgate, which facilitates the transfer of goods between the car body and the ground, thereby eliminating the problem of increased labor costs caused by manual handling.

[0003] However, in actual use, the goods being transported may be easy to slide and roll, or when the car is parked on a slope, it is very easy for the goods to slide and roll off the tailboard when the goods are transported through the tailboard in the later stage, which poses a great safety hazard. Although the industry has noticed this and has taken corresponding measures, including installing anti-skid strips on the tailboard, such as the aluminum alloy automobile tailboard disclosed in patent CN212890038U, which includes a front plate, a middle plate and a tailboard connected in sequence, and the front plate, the middle plate and the tailboard are provided with matching connecting parts between each other, and the joints of the connecting parts are connected as a whole by welding. The upper surfaces of the front plate, the middle plate and the tailboard are evenly distributed with a plurality of anti-skid strips, and at the same time, a bevel is provided below the front plate, and a plurality of anti-skid strips are also provided on the surface of the bevel. When in use, the anti-skid strips form convexities on the surfaces of the front plate, the middle plate and the tailboard to achieve the limitation of the goods, and also increase the friction when the goods are placed, which can prevent the goods from sliding and rolling to a large extent, improve the stability of the goods during transportation, and reduce the safety risk. However, since the existing anti-slip strip structure is a fixed structure, the protrusion formed on the surface of the car tailgate will not experience a large state change during use, so that in order to facilitate the subsequent loading and unloading of goods, the height of the anti-slip strip is limited. At the same time, its material is usually rubber and other materials, resulting in its limited ability to limit the position of the goods, that is, it is not effective in maintaining the stability of the goods during lifting, and it is difficult to meet the anti-slip transportation needs of large volume and heavy weight goods.

[0030] Specifically, the platform 1 includes two side plates 11 and a number of bearing cover plates 12. At this time, the two side plates 11 serve as support plates. The two side plates 11 are arranged parallel and spaced in one direction, so that a sufficiently large interval is left between the two side plates 11, which provides conditions for the subsequent installation of the bearing cover plates 12. In addition, a number of bearing cover plates 12 are arranged between the two side plates 11, and both ends of each bearing cover plate 12 are connected to the two side plates 11, thereby forming a platform 1 structure to meet the transportation needs of goods. At the same time, a number of bearing cover plates 12 are distributed in sequence along the arrangement direction of the side plates 11, so that the length direction of the side plates 11 can be covered by the bearing cover plates 12, providing a larger bearing area. It is worth pointing out that a hollow hole is opened in the bearing cover plate 12, that is, the bearing cover plate 12 is a hollow structure, which can not only meet the basic bearing requirements, but also reduce the use of materials and reduce the weight of the platform 1.

Figures 1 to 4As shown, a plurality of baffles 2 are arranged on a bearing cover plate 12 at the rear end of the platform 1, that is, the baffle 2 is installed only on the bearing cover plate 12 at the rear end of the platform 1. At this time, a plurality of baffles 2 are installed at intervals along the arrangement direction perpendicular to the side plates 11, that is, the baffles 2 are arranged in the lateral direction of the platform 1, which provides conditions for preventing the goods on the platform 1 from sliding and rolling down in the future. At the same time, a concave avoidance groove 121 is also provided on the bearing cover plate 12 on which the baffles 2 are installed. At this time, the lower end of the baffle 2 is hinged to the bearing cover plate 12, so that the baffle 2 can be turned over on the bearing cover plate 12.

In addition, when the baffle 2 is flipped downward, the baffle 2 is embedded in the avoidance groove 121, that is, the avoidance groove 121 provides a hidden space for the baffle 2 to flip downward. Moreover, after the baffle 2 is embedded in the avoidance groove 121, the surface of the baffle 2 is flush with the surface of the corresponding bearing cover plate 12, thereby maintaining the flatness of the surface of the platform 1 under normal circumstances, facilitating the transportation of goods, and making the structural design more reasonable.

[0032] More specifically, a plurality of connecting plates 122 are also provided on the bearing cover plate 12 provided with the baffle plate 2. At this time, the connecting plates 122 are all located in the avoidance groove 121, and both ends of the connecting plates 122 are fixedly connected to the groove wall of the avoidance groove 121, that is, the area in the avoidance groove 121 that is not embedded with the baffle plate 2 is filled by the connecting plates 122, and the flatness of the surface of the bearing cover plate 12 is maintained. At the same time, the structural strength of the bearing cover plate 12 at the avoidance groove 121 is also increased by the connecting plates 122, and the bearing capacity of the bearing cover plate 12 is ensured. When in use, the connecting plates 122 are located between two adjacent baffle plates 2 and divide the avoidance groove 121 into a plurality of chambers, and each of the separated chambers corresponds to a baffle plate 2, ensuring that there is a connecting structure between adjacent baffle plates 2 to ensure the structural strength of the bearing cover plate 12, and the structural design is more reasonable.

[0033] Figure 5 This is a structural diagram of a locking assembly of an automobile tailgate anti-skid mechanism of the utility model. Figures 1 to 5As shown, each baffle 2 is also provided with a locking assembly 3, through which the baffle 2 is temporarily locked in the avoidance groove 121, and the locking assembly 3 is unlocked and the baffle 2 is turned over only when the baffle 2 is needed later, thereby ensuring the flatness of the surface of the platform 1 under normal circumstances. At this time, the locking assembly 3 also includes a locking pin 31, a locking spring 32, a shift block 33, a connecting piece 34 and a latch 35. During installation, a locking hole 22 is first opened on the end of the baffle 2 away from the hinged bearing cover plate 12 along the direction perpendicular to the arrangement of the side plate 11, and at the same time, a movable hole 26 connected to the locking hole 22 is opened on the surface of the baffle 2, which provides conditions for the locking pin 31 in the locking hole 22 to be driven to move by the connecting piece 34 in the movable hole 26. Moreover, the movable hole 26 is a strip-shaped hole extending axially along the locking hole 22, and the locking pin 31 is inserted into the locking hole 22. At this time, the length of the locking hole 22 is much greater than the length of the locking pin 31, which provides conditions for the subsequent movement of the locking pin 31 in the locking hole 22. In addition, the bayonet 35 is fixed to the baffle 2 and one end is inserted into the locking hole 22.

Under normal circumstances, the locking spring 32 can apply a thrust to the locking pin 31, so that one end of the locking pin 31 can extend out of the locking hole 22, which provides conditions for the subsequent locking of the baffle 2 by the locking pin 31. When unlocking is required, the locking pin 31 only needs to be moved toward the locking hole 22 and the locking spring 32 is compressed. After unlocking is completed, the locking pin 31 can automatically reset to a state where one end extends out of the locking hole 22 under the reset action of the locking spring 32, thereby meeting the subsequent use requirement of pressing the baffle 2 to achieve locking. In addition, the shift block 33 is arranged outside the baffle 2, and the shift block 33 is arranged at the movable hole 26 on the baffle 2, and the shift block 33 and the locking pin 31 are connected by a connecting member 34. At this time, one end of the connecting member 34 passes through the movable hole 26 and is connected to the locking pin 31, and the other end of the connecting member 34 is connected to the shift block 33, so that when unlocking is required later, the locking pin 31 can be driven to move toward the locking hole 22 by the shift block 33 and the connecting member 34 to achieve unlocking, which is more convenient to operate. In addition, a socket 111 corresponding to the locking pin 31 is also provided on the side panel 11 or the connecting plate 122, that is, after the baffle 2 is flipped downward and embedded in the avoidance groove 121, the locking pin 31 extends one end out of the locking hole 22 under the action of the locking spring 32. At this time, the end extending out of the locking hole 22 is inserted into the socket 111, thereby realizing the connection between the baffle 2 and the side panel 11 or the baffle 2 and the connecting plate 122, thereby realizing temporary locking of the baffle 2.

[0034] More specifically, under normal circumstances, the end of the locking pin 31 away from the locking spring 32 will extend to the outside of the locking hole 22 and cooperate with the insertion hole 111 on the side plate 11 or the connecting plate 122. At this time, a guide slope 311 is also provided on the end of the locking pin 31 extending out of the locking hole 22, so that when the baffle 2 is flipped downward, the locking pin 31 can follow the baffle 2 to approach the side plate 11 or the connecting plate 122 and contact the side plate 11 or the connecting plate 122 through the guide slope 311. At this time, Continue to flip the baffle 2 downward, the locking pin 31 will retract under the action of the guiding inclined surface 311, so that the locking pin 31 can be retracted into the locking hole 22, so that the baffle 2 can continue to flip downward until it is in place, and after the baffle 2 is in place, the locking hole 22 and the insertion hole 111 are opposite, and the locking pin 31 retracted into the locking hole 22 can automatically reset under the action of the locking spring 32 so that one end of it extends out of the locking hole 22 and is inserted into the insertion hole 111, thereby realizing temporary locking of the baffle 2.

[0035] More specifically, a countersunk hole is provided on the shift block 33. At this time, a threaded hole is also provided on one end of the locking pin 31 and located in the locking hole 22, and the connecting piece 34 is preferably a screw.

During installation, limit pins 42 are provided at both ends of the torsion spring rotation groove 123, that is, a space with a limited length is formed in the torsion spring rotation groove 123 by two limit pins 42. At this time, a torsion spring 41 is installed in the torsion spring rotation groove 123 and both ends are abutted by the two limit pins 42, so that the torsion spring 41 is stably installed in the torsion spring rotation groove 123 to prevent the torsion spring 41 from moving. At the same time, the two force arms of the torsion spring 41 are extended from the notch of the torsion spring rotation groove 123 to the outside of the torsion spring rotation groove 123 and respectively abut against the notch of the torsion spring rotation groove 123 and the baffle 2, that is, a torsion structure is formed between the baffle 2 and the supporting cover plate 12 through the torsion spring 41, so that when the baffle 2 is flipped downward, the torsion spring 41 can be pressed down to store elastic potential energy. When the locking assembly 3 is unlocked and the baffle 2 can be flipped upward, the torsion spring 41 can release the elastic potential energy and push the baffle 2 to flip upward, thereby realizing the automatic flipping operation of the baffle 2, which is more convenient to use.

[0037] More specifically, the part where each baffle plate 2 is hinged to the corresponding bearing cover plate 12 is located in the avoidance groove 121 and at a notch on one side of the avoidance groove 121.

Moreover, after the rotating shaft 23 is installed in the connecting rotation groove 124, the centers of the first arc surface 241 and the second arc surface 1251 are arranged in a concentric state with the axis center of the rotating shaft 23, so that when the baffle 2 is flipped with the outer axis center of the rotating shaft 23, the first arc surface 241 and the second arc surface 1251 can always maintain a relative state without mutual interference, thereby ensuring that the baffle 2 can be flipped smoothly.

[0039] More specifically, a protruding block 251 is further provided on the plate surface 25 of the baffle 2 and on one side close to the avoidance groove 121. At this time, a limiting structure is formed on the bottom surface of the baffle 2 through the block 251, so that during subsequent installation, the end of a force arm of the torsion spring 41 that rests on the baffle 2 can rest on the block 251, thereby improving the accuracy of the installation position between the torsion spring 41 and the baffle 2, thereby improving the stability of the structure.
