Description

Technical Field

[0001] The present invention relates to the technical field of vehicle door installation, in particular to a vehicle and a vehicle door connecting mechanism. Background Art

[0002] When a car's side doors are opened after parking, traditional side doors often open outward from the vehicle. This requires a large opening space in narrow areas, making them prone to causing damage to pedestrians or the door itself. Therefore, scissor doors are now being installed on cars on the market to change the opening path of the side doors. However, traditional scissor doors open outward first, then upward after opening to a certain angle, making their movement less smooth. Summary of the Invention

[0007] In one embodiment, the spiral motion assembly includes a first fastener and a second fastener, one end of the spiral shaft is fixedly engaged with the first mounting seat through the first fastener, and the other end of the spiral shaft is fixedly engaged with the second mounting seat through the second fastener.

[0008] In one embodiment, the vehicle door connection mechanism also includes a spiral rotating block and a guide assembly, the spiral rotating block is provided with a sleeve hole, the spiral rotating block is sleeved on the spiral shaft through the sleeve hole, the connecting rod assembly is rotationally engaged with the spiral rotating block, the guide assembly is installed on the spiral rotating block, and the guide assembly is guide-engaged with the spiral guide rail.

[0009] In one embodiment, the guide assembly includes a first guide member and a second guide member, and the spiral guide rail includes a first spiral groove and a second spiral groove. The first spiral groove and the second spiral groove are both opened on the spiral shaft at intervals along the circumference of the spiral shaft, and the first spiral groove and the second spiral groove are both opened from one end of the spiral shaft toward the other end of the spiral shaft. The first guide member and the second guide member are arranged at intervals on the spiral rotation block, and the first guide member is matched with the first spiral groove guide, and the second guide member is matched with the second spiral groove guide.

[0010] In one embodiment, the door connection mechanism also includes a limit assembly, which is rotatably mounted on the first mounting base. The connecting rod assembly includes a first connecting rod, a second connecting rod, a first rotating shaft, a second rotating shaft and a third rotating shaft. One end of the first connecting rod is rotationally engaged with the spiral rotating block through the first rotating shaft, and the other end of the first connecting rod is rotationally engaged with the second connecting rod through the second rotating shaft. One end of the second connecting rod is connected to the car door, and the other end of the second connecting rod is rotationally engaged with the limit assembly through the third rotating shaft.

[0011] In one embodiment, the vehicle door connection mechanism further includes a second mounting base, and the second mounting base and the second connecting rod are mounted and matched with the vehicle door via the second mounting base.

[0012] In one embodiment, the limiting assembly includes a third mounting seat, a fourth mounting seat, a fourth rotating shaft and a limiting block, the third mounting seat and the fourth mounting seat are spaced apart on the first mounting base, the fourth rotating shaft is installed between the third mounting seat and the fourth mounting seat, one end of the fourth rotating shaft is installed and cooperated with the third mounting seat, and the other end of the fourth rotating shaft is installed and cooperated with the fourth mounting seat, the limiting block is rotatably mounted on the fourth rotating shaft, and one end of the second connecting rod is rotatably cooperated with the limiting block through the third rotating shaft.

In other words, the vehicle door must first be swung toward the outside of the vehicle body to an appropriate angle before the upward opening operation is performed. In this case, by adding a spiral guide rail to the spiral motion assembly, the curvature of the spiral guide rail can be determined according to the angle of separation of the vehicle door relative to the vehicle body, which ensures that the vehicle door does not collide or rub against the vehicle body when opening. Compared with the traditional scissor door structure, the above-mentioned door connection mechanism ensures that the lifting direction of the connecting rod assembly along the spiral motion assembly is adapted to the direction in which the connecting rod assembly drives the automobile door to rotate (that is, the two actions of the connecting rod assembly driving the automobile door to rotate and the connecting rod assembly moving along the spiral motion assembly can be performed simultaneously), and a spiral guide rail is added to the spiral motion assembly, so that when the automobile door is opened, the connecting rod assembly moves upward along the spiral motion assembly and rotates at a preset angle under the guidance of the spiral guide rail, thereby driving the automobile door to flip toward the outside of the vehicle body at an appropriate angle. At the same time, the connecting rod assembly will also obtain the rotation amount to drive the automobile door to rotate in the process of moving relative to the spiral motion assembly, thereby realizing the simultaneous opening and upward rotation of the automobile door, thereby making the movement of the automobile door smoother.

[0015] When the above-mentioned automobile is in use, a door connection mechanism is added to the automobile body. Compared with a traditional scissor door structure, the above-mentioned door connection mechanism ensures that the lifting direction of the connecting rod assembly along the spiral motion assembly is consistent with the direction in which the connecting rod assembly drives the automobile door to rotate (i.e., the connecting rod assembly drives the automobile door to rotate and the connecting rod assembly moves along the spiral motion assembly. Two actions can be performed simultaneously), and a spiral guide rail is added to the spiral motion assembly. When the automobile door is opened, the connecting rod assembly moves upward along the spiral motion assembly and rotates a preset angle under the guidance of the spiral guide rail, thereby driving the automobile door to flip toward the outside of the vehicle body at an appropriate angle. At the same time, the connecting rod assembly also obtains the amount of rotation that drives the automobile door to rotate during the process of moving relative to the spiral motion assembly, thereby achieving the synchronization of the automobile door's outward opening and upward rotation, thereby making the movement of the automobile door smoother.

[0026] Combine Figure 1 and Figure 3 As shown, in one embodiment, the door connection mechanism includes: a first mounting base 100, a connecting rod assembly 200 and a spiral motion assembly 300, the first mounting base 100 is used to be installed on the automobile body, the spiral motion assembly 300 is installed on the first mounting base 100, and a spiral guide rail 210 is provided on the side wall of the spiral motion assembly 300 along the circumference of the spiral motion assembly 300, the connecting rod assembly 200 is lifted and lowered with the spiral motion assembly 300 through the spiral guide rail 210, the spiral motion assembly 300 is used to be connected and cooperated with the automobile door 600 through the connecting rod assembly 200, the connecting rod assembly 200 obtains the rotation amount for driving the automobile door 600 to rotate by moving relative to the spiral motion assembly 300, and the lifting direction of the connecting rod assembly 200 along the spiral motion assembly 300 is adapted to the direction in which the connecting rod assembly 200 drives the automobile door 600 to rotate.

[0027] When the above-mentioned door connection mechanism is used, the installation position of the first mounting base 100 on the vehicle body is first determined based on the installation requirements of the vehicle body and the matching vehicle door. Then, the spiral motion assembly 300 is installed on the first mounting base 100, and the connecting rod assembly 200 and the spiral motion assembly 300 are installed so that the connecting rod assembly 200 can move along the spiral motion assembly 300. After the connecting rod assembly 200 and the spiral motion assembly 300 are installed, the connecting rod assembly 200 is installed and matched with the vehicle door 600. Furthermore, when selecting the connecting rod assembly 200, the amount of movement of the connecting rod assembly 200 must ensure that the vehicle door 600 can move from a fully closed position to a fully open position. Considering the influence of the vehicle body structure, the vehicle door 600 cannot be opened directly by rotating upward. That is, the vehicle door 600 must first be swung to an appropriate angle toward the outside of the vehicle body before the upward opening operation is performed. At this time, by adding a spiral guide rail 210 to the spiral motion component 300, the curvature of the spiral guide rail 210 can be determined according to the angle of separation of the door relative to the body, that is, to ensure that the door will not collide or rub against the body when opening. Compared with the traditional scissor door structure, the above-mentioned door connection mechanism ensures that the lifting direction of the connecting rod assembly 200 along the spiral motion assembly 300 is adapted to the direction in which the connecting rod assembly 200 drives the automobile door 600 to rotate (that is, the two actions of the connecting rod assembly 200 driving the automobile door 600 to rotate and the connecting rod assembly 200 moving along the spiral motion assembly 300 can be performed simultaneously), and a spiral guide rail 210 is added to the spiral motion assembly 300, so that when the automobile door 600 is opened, the connecting rod assembly 200 moves upward along the spiral motion assembly 300 and rotates a preset angle under the guidance of the spiral guide rail 210, thereby driving the automobile door 600 to flip toward the outside of the vehicle body at an appropriate angle. At the same time, the connecting rod assembly 200 will also obtain the rotation amount to drive the automobile door 600 to rotate during the movement relative to the spiral motion assembly 300, thereby realizing the simultaneous opening and upward rotation of the automobile door 600, thereby making the movement of the automobile door 600 smoother.

[0028] Combine Figures 1 to 3As shown, in one embodiment, the spiral motion assembly 300 includes a first mounting seat 310, a second mounting seat 320 and a spiral shaft 330, the first mounting seat 310 and the second mounting seat 320 are installed on the first mounting base 100 at intervals, the spiral shaft 330 is located between the first mounting seat 310 and the second mounting seat 320, one end of the spiral shaft 330 is installed and cooperated with the first mounting seat 310, and the other end of the spiral shaft 330 is installed and cooperated with the second mounting seat 320, the spiral guide rail 210 is arranged on the side wall of the spiral shaft 330 along the circumference of the spiral shaft 330, and the spiral guide rail 210 extends from one end of the spiral shaft 330 toward the other end of the spiral shaft 330. The spiral motion assembly 300 includes a first fastener 301 and a second fastener 302. One end of the spiral shaft 330 is fixedly matched with the first mounting seat 310 through the first fastener 301, and the other end of the spiral shaft 330 is fixedly matched with the second mounting seat 320 through the second fastener 302. Specifically, the first mounting seat 310 and the second mounting seat 320 can be spliced and fixed with the first mounting base 100 or integrally formed. The spacing between the first mounting seat 310 and the second mounting seat 320 and the length of the spiral shaft 330 are determined according to the range of motion of the car door 600. Furthermore, the first fastener 301 and the second fastener 302 are screws or buckles. The first fastener 301 can effectively ensure the fixing effect of the first mounting seat 310 and one end of the spiral shaft 330, and the second fastener 302 can effectively ensure the fixing effect of the second mounting seat 320 and the other end of the spiral shaft 330.

[0029] Combine Figure 1As shown, in one embodiment, the vehicle door connection mechanism further includes a spiral rotation block 340 and a guide assembly 350. The spiral rotation block 340 is provided with a sleeve hole, and the spiral rotation block 340 is sleeved on the spiral shaft 330 through the sleeve hole. The connecting rod assembly 200 is rotationally engaged with the spiral rotation block 340. The guide assembly 350 is mounted on the spiral rotation block 340, and the guide assembly 350 is guided and engaged with the spiral guide rail 210. Specifically, the guide assembly 350 is a guide rod or a guide block. After the helical rotation block 340 is mounted on the helical shaft 330, the guide assembly 350 is correspondingly inserted into the helical guide rail 210. When the automobile door 600 is opened or closed, the guide assembly 350 reciprocates within the guide range of the helical guide rail 210, thereby driving the first mounting block to move along the lifting direction of the helical shaft 330 and driving the first mounting block to rotate along the helical shaft 330. This achieves the simultaneous outward opening and upward rotation of the automobile door 600, thereby making the movement of the automobile door 600 smoother. Furthermore, the connecting rod assembly 200 utilizes the helical rotation block 340 to rotate in coordination with the helical shaft 330, effectively ensuring the rotational effect between the connecting rod assembly 200 and the helical shaft 330.

[0030] Combine Figure 1 and Figure 2 As shown, in one embodiment, the guide assembly 350 includes a first guide member and a second guide member, and the spiral guide rail 210 includes a first spiral groove 211 and a second spiral groove 212. The first spiral groove 211 and the second spiral groove 212 are both opened on the spiral shaft 330 at intervals along the circumference of the spiral shaft 330, and the first spiral groove 211 and the second spiral groove 212 are both opened from one end of the spiral shaft 330 toward the other end of the spiral shaft 330. The first guide member and the second guide member are arranged at intervals on the spiral rotation block 340, and the first guide member guides and cooperates with the first spiral groove 211, and the second guide member guides and cooperates with the second spiral groove 212. Specifically, the first guide member and the second guide member are both guide rods or guide blocks. The above embodiment can effectively improve the rotation guiding effect of the spiral guide rail 210 on the spiral rotation block 340.

[0031] Combine Figure 1As shown, in one embodiment, the door connection mechanism further includes a limiting assembly 400, which is rotatably mounted on the first mounting base 100. The connecting rod assembly 200 includes a first connecting rod 220, a second connecting rod 230, a first rotating shaft 240, a second rotating shaft 250, and a third rotating shaft 260. One end of the first connecting rod 220 is rotatably engaged with the spiral rotating block 340 via the first rotating shaft 240, and the other end of the first connecting rod 220 is rotatably engaged with the second connecting rod 230 via the second rotating shaft 250. One end of the second connecting rod 230 is connected to and engaged with the automobile door 600, and the other end of the second connecting rod 230 is rotatably engaged with the limiting assembly 400 via the third rotating shaft 260. Specifically, the limiting assembly 400 is a rotating seat or a rotating shaft. The first rotating shaft 240, the second rotating shaft 250, and the third rotating shaft 260 enable a rotatable connection between the first connecting rod 220 and the second connecting rod 230, a rotatable connection between the first connecting rod 220 and the spiral rotating block 340, and a rotatable connection between the second connecting rod 230 and the limiting assembly 400. Furthermore, the limiting assembly 400 is rotatably mounted on the first mounting base 100. That is, after the limiting assembly 400 and the second connecting rod 230 are mounted and matched, when the automobile door 600 is opened, the spiral rotating block 340 rotates along the spiral shaft 330. At this time, the spiral rotating block 340 drives the first connecting rod 220 to swing accordingly. As the first connecting rod 220 swings, the second connecting rod 230 also moves accordingly, that is, the second connecting rod 230 drives the limiting assembly 400 to swing accordingly. Furthermore, during the opening process of the car door 600, the spiral rotating block 340 moves axially along the spiral shaft 330, and the first rotating shaft 240 moves toward the third rotating shaft 260. At this time, the second rotating shaft 250 will rotate around the third rotating shaft 260 under the action of the second connecting rod 230, thereby realizing the up and down flipping of the car door 600 through the connecting rod assembly 200.

[0032] Combine Figure 1 As shown, in one embodiment, the vehicle door connection mechanism further includes a second mounting base 500, and the second mounting base 500 and the second connecting rod 230 are mounted and matched with the vehicle door 600 via the second mounting base 500. Specifically, by adding the second mounting base 500 to the second connecting rod 230, the mounting contact area between the second connecting rod 230 and the vehicle door 600 can be increased. That is, the above embodiment effectively improves the installation effect of the connecting rod assembly 200 and the vehicle door.

[0033] Combine Figure 1As shown, in one embodiment, the limiting assembly 400 includes a third mounting seat 410, a fourth mounting seat 420, a fourth rotating shaft 430, and a limiting block 440. The third mounting seat 410 and the fourth mounting seat 420 are spaced apart on the first mounting base 100. The fourth rotating shaft 430 is installed between the third mounting seat 410 and the fourth mounting seat 420. One end of the fourth rotating shaft 430 is mounted and engaged with the third mounting seat 410, and the other end of the fourth rotating shaft 430 is mounted and engaged with the fourth mounting seat 420. The limiting block 440 is rotatably mounted on the fourth rotating shaft 430. One end of the second connecting rod 230 is rotatably engaged with the limiting block 440 via the third rotating shaft 260. Specifically, the third mounting seat 410 and the fourth mounting seat 420 can be spliced and fixed to the first mounting base 100 or integrally formed. The spacing between the third mounting seat 410 and the fourth mounting seat 420 is determined based on the structure of the second connecting rod 230. Furthermore, a sleeve hole is opened on the limit block 440, and the limit block 440 is sleeved on the fourth rotating shaft 430 through the sleeve hole. After the limit block 440 is sleeved on the fourth rotating shaft 430, without affecting the rotation of the limit block 440 along the fourth rotating shaft 430, the two ends of the limit block 440 can respectively conflict with the third mounting seat 410 and the fourth mounting seat 420, thereby ensuring the rotation effect of the second connecting rod 230 and the limit assembly 400.

[0034] In one embodiment, the axis of the fourth rotating shaft 430 is located on the same reference line as the axis of the screw shaft 330. Specifically, the above embodiment ensures the rotation accuracy of the connecting rod assembly 200 relative to the first mounting base 100, making the overall rotation of the connecting rod assembly 200 smoother.

[0035] Combine Figure 1 and Figure 3As shown, in one embodiment, a car includes the door connection mechanism described above, and also includes a car body and a car door 600. The door connection mechanism is installed on the car body, and the car door 600 is installed and cooperated with the door connection mechanism. When the above car is in use, the door connection mechanism is added to the car body. Compared with the traditional scissor door structure, the above-mentioned door connection mechanism ensures that the lifting direction of the connecting rod assembly 200 along the spiral motion assembly 300 is adapted to the direction in which the connecting rod assembly 200 drives the automobile door 600 to rotate (that is, the two actions of the connecting rod assembly 200 driving the automobile door 600 to rotate and the connecting rod assembly 200 moving along the spiral motion assembly 300 can be performed simultaneously), and a spiral guide rail 210 is added to the spiral motion assembly 300, so that when the automobile door 600 is opened, the connecting rod assembly 200 moves upward along the spiral motion assembly 300 and rotates a preset angle under the guidance of the spiral guide rail 210, thereby driving the automobile door 600 to flip toward the outside of the vehicle body at an appropriate angle. At the same time, the connecting rod assembly 200 will also obtain the rotation amount to drive the automobile door 600 to rotate during the movement relative to the spiral motion assembly 300, thereby realizing the simultaneous opening and upward rotation of the automobile door 600, thereby making the movement of the automobile door 600 smoother.

[0036] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
