Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle door handles, and more specifically, relates to a door handle mounting structure, a vehicle door, and a vehicle. Background Art

[0002] Currently, the door lock systems of automobiles are becoming increasingly mature. Most vehicle models have abandoned the traditional upward-opening handles and adopted outward-pulling handles. The setting of the outward-pulling handles not only reduces the wind resistance of the vehicle but also makes the vehicle door more streamlined and more beautiful.

[0003] For outward-pulling handles, some vehicle models choose to use a cable structure to trigger unlocking. Generally, the cable is horizontally arranged inside the vehicle door and needs to be bent at a 270° angle inside the door before it can be connected downward to the door lock. The above structure causes the cable to be subjected to a large force during movement and often has a risk of breakage, affecting the stability and reliability of use. Summary of the Invention

[0028] Please refer to Figures 1 to 6 , and now the door handle mounting structure, door and vehicle provided by the present invention will be described. The door handle mounting structure includes a mounting seat 1, a handle 2, a swing seat 3, a first gear 4 and a cable 5. The mounting seat 1 is connected to the inner side of the outer door panel, the handle 2 is hinged to the outer side of the outer door panel, the swing seat 3 is rotatably connected to the mounting seat 1 and can swing vertically, the first gear 4 is rotatably connected to the mounting seat 1, the cable 5 is connected to the first gear 4, and a second gear 6 meshing with the first gear 4 is provided at the end of the swing seat 3;

[0029] Wherein, a swing arm 31 extending towards the inner side of the vehicle body is provided on the swing seat 3, and a hook portion 21 extending to the inner side of the outer door panel is provided at the rear end of the handle 2. When the handle 2 swings horizontally around the hinge point, the hook portion 21 can press against the swing arm 31 to swing vertically and drive the first gear 4 to rotate through the second gear 6 to pull up the cable 5 upwards and unlock the door.

[0030] Compared with the prior art, the door handle mounting structure provided in this embodiment uses the hook portion 21 on the handle 2 to push the swing arm 31 of the swing seat 3 towards the outer side of the vehicle body, thereby driving the swing seat 3 to swing vertically. At the same time, the second gear 6 and the first gear 4 rotate and engage relatively, and then the cable 5 is pulled upwards through the first gear 4 to realize the unlocking operation of the door. The above structure is directly connected to the cable 5 through the first gear 4, so that the cable 5 maintains an up-and-down extension state, avoiding the winding caused by the change of the angle of the cable 5 and improving the reliability of the unlocking action.

[0031] In this embodiment, when the handle 2 on the outside of the door outer panel is pulled outward, the rear end of the handle 2 can swing outward, driving the hook portion 21 on the inside of the handle 2 to push the swing arm 31 toward the outside of the vehicle body, thereby driving the swing seat 3 to swing vertically toward the inside of the vehicle body. While the swing seat 3 swings vertically, the second gear 6 at its end can mesh with the first gear 4 to drive the first gear 4 to rotate, so that the pull wire 5 connected to the first gear 4 moves up with the rotation of the first gear 4, thereby unlocking the door. The cooperation of the first gear 4 and the second gear 6 can ensure the stability of the movement, so that the pull wire 5 is evenly stressed during the pulling process, moves smoothly, and avoids the problem of breakage due to violent pulling.

[0032] Specifically, the swing axis of the swing seat 3, the main axis of the first gear 4 and the main axis of the second gear 6 are arranged parallel to each other, that is, they are arranged along the front and rear direction of the vehicle body. The main axis of the first gear 4 is coaxially arranged with the main axis of the swing seat 3, so that the second gear 6 can maintain a state of mutual meshing with the first gear 4, ensuring the effective driving of the second gear 6 on the first gear 4 and improving the stability and smoothness of power transmission.

[0033] In some possible implementations, the first gear 4 and the pull wire 5 are as follows: Figure 1 , Figure 2 , Figure 5 and Figure 6 See the structure shown. Figure 1 , Figure 2 , Figure 5 and Figure 6 An axially penetrating installation cavity 41 is provided on the first gear 4, a through hole 42 communicating with the installation cavity 41 is provided on the peripheral wall of the first gear 4, and an installation rod 51 inserted into the installation cavity 41 is provided at the end of the pull wire 5. The pull wire 5 passes through the through hole 42 and extends downward to be connected with the door lock.

[0034] In this embodiment, while the second gear 6 drives the first gear 4 to rotate, the cable 5 moves up synchronously with the first gear 4. In order to prevent the cable 5 from affecting the first gear 4 during the rotation of the first gear 4, a mounting rod 51 is provided at the end of the cable 5 and is arranged perpendicular to the extension direction of the cable 5. The first gear 4 is provided with a mounting cavity 41 for mounting the mounting rod 51. The mounting cavity 41 penetrates along the axial direction of the first gear 4. When the first gear 4 rotates, the mounting rod 51 can be driven to rotate around the axis of the first gear 4, thereby forming an upward pulling effect on the lower cable 5, so that the cable 5 can unlock the door lock below, thereby realizing the opening of the door.

[0035] When the car door is in the locked state, the installation cavity 41 is located below the inner side of the first gear 4. When the handle 2 is pulled outwards to drive the swing seat 3 to swing and simultaneously drive the first gear 4 to rotate, as the first gear 4 rotates, the cable 5 moves upwards and can gradually fit on the circumferential wall of the first gear 4. Since only a circumferential partial area of the first gear 4 needs to be meshed with the second gear 6 to achieve the effect of unlocking the cable 5 by pulling, therefore, except for the above-mentioned meshing area, the circumferential walls of other parts of the second gear 6 are cylindrical circumferential walls, which are convenient for fitting with the cable 5, avoiding abrasion of the cable 5, and at the same time can also avoid adhesion or winding of the cable 5 on the outer periphery of the first gear 4, ensuring the effectiveness of unlocking.

[0036] The above structural layout enables the cable 5 to be hidden in the mounting seat 1, which can ensure that the movement of the cable 5 is a linear movement without the risk of bending and breaking. On this basis, please refer to Figure 5 , a wire groove 43 for the cable 5 to enter is provided on the above-mentioned cylindrical circumferential wall. The wire groove 43 extends along the circumference of the first gear 4 and communicates with the through port 42. The wire groove 43 is a concave groove body. When the first gear 4 rotates, the cable 5 can smoothly enter the wire groove 43 along the outer circumferential wall of the first gear 4. The wire groove 43 forms a limiting effect on the cable 5 to avoid the cable 5 from detaching from the circumferential wall of the first gear 4 and ensure the effectiveness of the unlocking action.

[0037] In some embodiments, the above-mentioned characteristic mounting seat 1 can adopt the structure as Figure 3 shown. Refer to Figure 3 , a limiting clamping seat 11 is provided on the mounting seat 1 below the first gear 4. The limiting clamping seat 11 has a limiting cavity 12 that penetrates up and down for the cable 5 to pass through, and the limiting cavity 12 has an opening facing the inner side of the vehicle body.

[0038] In this embodiment, during the process of the first gear 4 pulling the cable 5 upwards, in order to enable the cable to move upwards smoothly and avoid position interference with other parts of the mounting seat 1, a limiting clamping seat 11 is also provided at the lower part of the mounting seat 1. The limiting cavity 12 of the limiting clamping seat 11 can allow the cable 5 to pass through, facilitating the formation of a limit on the cable 5 and avoiding the horizontal swing of the cable 5. The opening of the limiting cavity 12 facing the inner side of the vehicle body is convenient for smoothly placing the cable 5 into the limiting cavity 12 during installation, reducing the installation difficulty and improving the installation efficiency.

[0039] Specifically, the limiting clamping seat 11 can be set as two block-shaped members or strip-shaped members spaced apart front and back. A limiting cavity 12 that can limit is formed between the two block-shaped members or strip-shaped members, which can also play a role in limiting the cable 5.

[0040] In some possible implementation manners, the above-mentioned characteristic swing seat 3 adopts the structure as Figure 1 shown. Refer to Figure 1, the swing seat 3 is movably connected to the mounting seat 1 through the first rotating shaft 33. A first return spring 34 for driving the swing seat 3 to return to its original position is sleeved on the first rotating shaft 33. Two ends of the first return spring 34 are respectively connected to the first rotating shaft 33 and the swing seat 3.

[0041] In this embodiment, the first rotating shaft 33 is used to mount the swing seat 3. The first return spring 34 sleeved on the first rotating shaft 33 can exert a pressing and resetting effect on the swing seat 3. After the pushing action of the handle 2 is lost, the swing seat 3 can swing around the first rotating shaft 33 to its initial state under the action of the first return spring 34, saving the trouble of manual reset.

[0042] In some embodiments, the above-mentioned swing seat 3 may adopt a structure as shown in Figures 1 to 2 . Refer to Figures 1 to 2 , a fitting seat 32 sleeved on the outer periphery of the first rotating shaft 33 and rotatably matched with the first rotating shaft 33 is connected to the swing seat 3. A clamping groove 35 extending axially is provided on the fitting seat 32. One end of the first return spring 34 is connected to the first rotating shaft 33, and the other end is clamped in the clamping groove 35.

[0043] In this embodiment, the swing seat 3 is rotatably connected to the first rotating shaft 33 through the fitting seat 32, and the inner end of the swing arm 31 is connected to the fitting seat 32. The clamping groove 35 provided on the fitting seat 32 facilitates the installation of the first return spring 34. Based on the connection of one end of the first return spring 34 to the rotating shaft, the other end can be clamped in the clamping groove 35 of the fitting seat 32. When the swing seat 3 swings, the first return spring 34 is gradually tensioned until the handle 2 is released and the swing arm 31 loses the pushing action of the hooking portion 21. At this time, under the action of the first return spring 34, the swing seat 3 returns to its initial state.

[0044] On this basis, a sleeve 37 rotatably sleeved on the outer periphery of the first rotating shaft 33 is provided in the fitting seat 32. The sleeve 37 and the first rotating shaft 33 can rotate relative to each other, ensuring that the mounting seat 1 and the swing arm 31 can be reliably connected to the first rotating shaft 33.

[0045] In some possible implementation manners, refer to Figure 3 , the door handle mounting structure includes an overload rocker arm 7 adjacent to the swing seat 3. The overload rocker arm 7 is rotatably connected to the mounting seat 1 through a second rotating shaft 72. A limiting column 36 extending outward is provided at the end of the swing seat 3. An arc-shaped limiting groove 71 for the limiting column 36 to penetrate is provided on the overload rocker arm 7. A second return spring 73 is sleeved on the second rotating shaft 72. The limiting column 36 can press against one end of the limiting groove 71 under the action of the swing seat 3 to drive the overload rocker arm 7 to swing and tension the second return spring 73.

[0046] In this embodiment, in order to avoid excessive pulling force on the pull wire 5 during the process of pulling the handle 2, an overload rocker arm 7 is further provided at one end of the swing seat 3 away from the second gear 6. A circumferentially extending limit groove 71 is provided on the overload rocker arm 7, and a limit column 36 is provided on the swing seat 3, which penetrates the limit groove 71 and can slide relative to the limit groove 71.

[0047] After the swing seat 3 swings to a specific position relative to the first rotating shaft 33, the limit column 36 contacts the end of the limit groove 71 close to the center axis of the vehicle body, which can drive the overload rocker arm 7 to swing vertically toward the inner side of the vehicle body around the second rotating shaft 72. At this time, the movement resistance will increase smoothly, thereby forming a reverse force on the swing seat 3, which is convenient for absorbing movement energy and protecting the pull wire 5 structure from violent impact.

[0048] In addition, when the vehicle makes a sharp turn or a side collision occurs, the handle 2 will also be driven open by inertia. The setting of the overload rocker arm 7 can also play a protective role to prevent the door from opening without reason, which helps to improve the safety of passengers.

[0049] Specifically, the first rotating shaft 33 is arranged on the side of the second rotating shaft 72 close to the center axis of the vehicle body, which can make full use of the swing space of the swing seat 3 to arrange the overload rocker arm 7, thereby improving the utilization rate of the space and saving space occupation.

[0050] On this basis, the second reset spring 73 provided on the second rotating shaft 72 can effectively reset the overloaded rocker arm. When the swing seat 3 drives the overloaded rocker arm 7 to reach the limit position through the limit column 36, the swing arm 31 of the swing seat 3 loses the pushing effect of the hook portion 21. At this time, under the action of the second reset spring 73, the overloaded rocker arm 7 can smoothly return to the initial state, and the overload protection is performed for the next swing of the swing seat 3, which has a reliable protection effect.

[0051] In some possible implementations, the above-mentioned characteristic mounting seat 1 is used as follows Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The mounting base 1 is connected to the outer panel of the vehicle door through a connecting piece 13. Two guide strips 14 are arranged at intervals in the upper and lower directions on the mounting base 1. A through cavity is formed between the two guide strips 14 for the hook part 21 to extend into. The guide strip 14 is slidably matched with the hook part 21. The hook part 21 has a plate-shaped hook head 22 that is bent forward to press the swing arm 31 toward the outside of the vehicle body.

[0052] In this embodiment, the mounting base 1 is installed on the inner side of the vehicle door outer panel through the connecting member 13. The mounting base 1 is provided with a through hole for the hook portion 21 to pass through. The inner side of the mounting base 1 is also provided with a guide strip 14 located at the edge of the through hole. The guide strip 14 forms an effective limit for the hook portion 21 in the up and down directions.

[0053] In some embodiments, the above-mentioned feature mounting seat 1 can adopt a structure as shown in Figure 1 and Figure 3 . Referring to Figure 1 and Figure 3 , a shielding cover 15 extending upward is provided on the mounting seat 1 to shield the outer upper parts of the swing seat 3 and the first gear 4, and reinforcing ribs 16 are respectively provided on the inner and outer side walls of the mounting seat 1 and are arranged in a cross pattern.

[0054] In this embodiment, the shielding cover 15 on the mounting seat 1 has a good water-blocking effect, preventing external rain and snow from directly falling on components such as the first gear 4 or the second gear 6 and affecting the normal use of the structure, and can also prevent the wire rope 5 from freezing due to water ingress in winter, ensuring the effectiveness of unlocking the wire rope 5.

[0055] A plurality of reinforcing ribs 16 are provided on the inner side of the mounting seat 1, forming a plurality of cavity structures on the inner side of the mounting seat 1, ensuring the structural strength of the mounting seat 1 without increasing the material consumption of the mounting seat 1.

[0056] Based on the same inventive concept, an embodiment of the present application further provides a vehicle door, and the above-mentioned vehicle door includes a door handle mounting structure. When the handle 2 is pulled, the above-mentioned vehicle door can drive the swing seat 3 to swing vertically, and then drive the first gear 4 to rotate by using the second gear 6 and pull the wire rope 5 upward, realizing the unlocking operation of the vehicle door. This structure keeps the wire rope 5 in a vertically extending state, improving the reliability of the unlocking action.

[0057] Based on the same inventive concept, an embodiment of the present application further provides a vehicle, and the above-mentioned vehicle includes a vehicle door. The vehicle door of the above-mentioned vehicle can be effectively unlocked when the handle 2 is pulled, realizing effective control of the wire rope 5 and improving the effectiveness of the unlocking action.

[0058] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
