[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0034] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.
[0035] Please see Figure 1-11 This invention provides a technical solution: a multi-functional tailgate for a commercial pickup truck, including a frame body 1, a tailgate 2 hinged to the inner wall of the frame body 1, a pedal 3 fixedly connected to the rear outer wall of the frame body 1, a pressure switch 4 fixedly connected to the upper surface of the pedal 3, a buzzer 5 fixedly connected to the side wall of the pedal 3, a support mechanism 6 provided on the rear side of the outer wall of the tailgate 2, an exhibition mechanism 7 provided on the front side of the tailgate 2, the pressure switch 4 electrically connected to a control module, the control module electrically connected to the vehicle system, and the control module electrically connected to the buzzer 5. The pressure switch 4 can transmit whether pressure is sensed to the control module, the vehicle system can transmit whether the parking brake is activated to the control module, and the control module can control the buzzer 5 to work.
[0036] When in use, after parking, the tailgate 2 is opened. Since the outer wall of the tailgate 2 is hinged to the inner wall of the frame body 1, the tailgate 2 is tilted backward, which will cause the outer wall of the tailgate 2 to contact the outer wall of the pedal 3, thereby making the tailgate 2 open stably. After the tailgate 2 is opened, it will press on the upper side of the pressure switch 4, causing the pressure switch 4 to sense the pressure. When the pressure switch 4 senses the pressure and the parking brake is not activated, the control module will activate the buzzer 5 to sound an alarm, warning the operator that the vehicle has not activated the parking brake, so as to avoid injury to the operator due to the vehicle not stopping properly and to avoid damage to goods and samples due to the movement of the vehicle.
[0037] The support mechanism 6 includes a rod 604 and a sleeve 603. The rod 604 and sleeve 603 can deflect on the outer wall of the tailgate 2. After deflection, the lower end of the rod 604 contacts the ground. The support mechanism 6 also includes an arc-shaped groove 601, which is a recess formed on the rear side of the tailgate 2. A hinge block 602 is fixedly connected to the inner wall of the arc-shaped groove 601. The inner wall of the hinge block 602 is hinged to one end of the sleeve 603. The rod 604 is inserted into the inside of the sleeve 603. A gear groove is formed on the rod 604. A rack 605 is fixedly connected to the inner wall of the gear groove. A gear 606 meshes with the outer wall of the rack 605. A pivot 607 is fixedly connected to the inner wall of the gear 606. One end of the pivot 607 passes through the sleeve 603 and extends to the end of the sleeve 603. On the outside, the outer wall of the rotating pile 607 and the inner wall of the insert 603 are rotatably connected by bearings. A first spring 608 is fixedly connected to the inner wall of the rotating pile 607. A rotating block 609 is fixedly connected to one end of the first spring 608. The outer wall of the rotating block 609 and the inner wall of the rotating pile 607 are both hexagonal structures. The rotating block 609 cannot rotate relative to the rotating pile 607. The outer wall of the rotating block 609 is slidably connected to the inner wall of the rotating pile 607. One end of the rotating block 609 extends to the outside of the rotating pile 607. Several limiting blocks 611 are fixedly connected around the rotating block 609 on the outer wall of the insert 603. A limiting rod 610 is fixedly connected to the side of the outer wall of the rotating block 609 near the limiting block 611. One end of the limiting rod 610 extends between the several limiting blocks 611.
[0038] After the tailgate 2 is opened, the insert 603 can be pried downwards, causing the insert 603 and insert rod 604 to deflect to the lower end of the tailgate 2 facing the ground in an open state. Then, the rotating block 609 is pulled outwards from the insert 603, causing the first spring 608 to stretch and deform. The rotating block 609 drives the limiting rod 610 to disengage from the limiting block 611. The rotating block 609 is then rotated, causing the rotating post 607 and the first spring 608 to rotate. This causes the first spring 608 to rotate due to its interaction with the rack. The meshing relationship of 605 drives the rack 605 and the insert rod 604 to move, thereby adjusting the length of the insert rod 604 extending out of the insert tube 603, so that the lower end of the insert rod 604 stably contacts the ground, forming a stable support for the tailgate 2, making it safer when the sample is displayed on the upper side of the tailgate 2. When the insert tube 603 is in the retracted state, it is tightly hinged to the outer wall of the hinge block 602 and contacts the inner wall of the arc groove 601, so it will not fall off by itself due to the vertical state of the tailgate 2 or the movement of the vehicle.
[0039] Exhibition structure 7 includes a connecting assembly and a liftable support plate 706 on the connecting assembly. The support plate 706 can be raised to the outside of the tailgate 2. The connecting assembly includes a fixing box 701. The outer wall of the tailgate 2 has a mounting groove. The fixing box 701 is adhered to the inner wall of the mounting groove. A cover plate 702 is hinged to the inner wall of the fixing box 701. A slide groove 703 is fixedly connected to the inner wall of the fixing box 701. A hinge shaft 704 is slidably connected to the inner wall of the fixing box 701 at the middle of the slide groove 703 via a slide rail. The hinge shaft 704 cannot rotate relative to the fixing box 701. Two hinge rods 705 are cross-hinged to the outer wall of the hinge shaft 704 via torsion springs. The lower ends of the hinge rods 705 are slidably connected to the inner wall of the slide groove 703. A support plate 706 is slidably connected to the upper end. The support plate 706 has an installation hole. A fixing cylinder 707 is fixedly connected to the inner wall of the installation hole. A sample box 708 is placed inside the fixing cylinder 707. The upper diameter of the sample box 708 is larger than the upper diameter of the fixing cylinder 707. Two connecting strips 709 are hinged to one side of the outer wall of the support plate 706. A sub-plate 710 is hinged to one end of the connecting strip 709. A sample groove 711 is fixedly connected to the outer wall of the sub-plate 710. The fixing box 701 is also provided with a fixing mechanism 712. The upper height of the sample box 708 is higher than the upper height of the sample groove 711. The upper surface of the sample box 708 is in contact with the outer wall of the cover plate 702. The outer wall of the cover plate 702 is in contact with the inner wall of the installation groove on the tailgate 2.
[0040] When the cover 702 is in the retracted state, it is tightly hinged to the inner wall of the fixed box 701 and will not unfold on its own due to the vertical position of the tailgate 2 or vehicle movement. A locking device can be installed at the contact point between the outer wall of the cover 702 and the inner wall of the fixed box 701 to prevent the fixed box 701 from unfolding on its own. After the tailgate 2 is opened, the cover 702 can be pried up to unfold. When the cover 702 no longer presses against the upper side of the sample box 708, since the hinge shaft 704 is not rotatable and the torsion spring at the connection between the hinge rod 705 and the hinge shaft 704 is in a tightened state, the elastic force of the torsion spring will cause the two hinge rods 705 to tend to close, allowing the lower end of the hinge rod 705 to slide inside the slide groove 703. The upper end of 5 slides on the surface of the support plate 706, thereby supporting the support plate 706 and the hinge shaft 704 to rise, so that the support plate 706 moves to the upper side of the mounting groove. At this time, the exhibits inside the sample box 708 can be viewed by customers, and temporary goods can be placed inside the sample groove 711 for exhibition. After the exhibition is over, the cover plate 702 and the sample box 708 can be pressed down, so that the sample box 708 and the support plate 706 move down, thereby causing the hinge shaft 704 to move down. The hinge rods 705 cross each other, so that the torsion spring at the connection between the hinge shaft 704 and the hinge rod 705 stores energy. Then the support plate 706 moves down to the inside of the mounting groove, and the fixing box 701 resets to close the upper side of the sample box 708.
[0041] An impact sensor 713 is fixedly connected to the inner wall of the mounting slot on the tailgate 2. An airbag detonator 714 is fixedly connected to the side of the impact sensor 713 near the fixed box 701. A buffer sheet 715 is fixedly connected to the side of the airbag detonator 714 near the fixed box 701. The outer wall of the buffer sheet 715 is fixedly connected to the outer wall of the fixed box 701. The impact sensor 713 is electrically connected to the control module. The control module is electrically connected to the airbag detonator 714. The control module can activate the airbag detonator 714 after receiving the impact sensor 713 detecting an impact.
[0042] In the event of a severe rear-end collision during vehicle operation, the impact sensor 713 located at the rear will instantly detect the impact and activate the airbag detonator 714 via the control module to detonate the airbag. This causes the airbag to impact the buffer plate 715 and the fixing box 701, causing the fixing box 701 to instantly detach from the mounting slot and fall forward into the vehicle compartment. Furthermore, the presence of the insert 603 and insert rod 604 can reduce the degree of deformation of the tailgate 2, thereby preventing damage to the samples inside the fixing box 701 and ensuring the safety of the goods.
[0043] The fixing mechanism 712 includes a mounting plate 201. The outer wall of the mounting plate 201 is fixedly connected to the lower side of the fixing cylinder 707. A clamping block 202 is slidably connected to the lower side of the outer wall of the mounting plate 201. A second spring 203 is fixedly connected to the outer wall of the mounting plate 201. The other end of the second spring 203 is fixedly connected to the outer wall of the clamping block 202. The outer wall of the clamping block 202 is in contact with the outer wall of the sample box 708. A push block 204 is also fixedly connected to the inner wall of the fixing box 701. The outer wall of the push block 204 is in contact with the outer wall of the clamping block 202. The surfaces of the push block 204 and the clamping block 202 that are in contact with each other are both inclined surfaces.
[0044] After the support plate 706 and the fixing cylinder 707 move down into the mounting groove, the outer wall of the clamping block 202 will contact the outer wall of the push block 204. Since both the outer walls of the clamping block 202 and the push block 204 are inclined, the clamping block 202 will slide towards the sample box 708, thereby squeezing the second spring 203 and causing the second spring 203 to contract and deform, so that the clamping block 202 can stably clamp the sample box 708, thereby avoiding the impact of shaking on the sample box 708 and the fixing cylinder 707 during transportation. When the sample box 708 is moved up to display the goods, the clamping block 202 separates from the push block 204. At this time, the outer wall of the clamping block 202 is not squeezed by the push block 204, and the second spring 203 rebounds and drives the clamping block 202 away from the sample box 708, so that the sample box 708 can be freely inserted and removed inside the fixing cylinder 707, thereby facilitating the removal of the display goods.
[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
