Description
Technical Field
[0001] The present application relates to the technical field of vehicle door handles, and particularly to an exterior vehicle door handle and a vehicle. Background Art
[0002] As the styles of vehicle door handles are increasing, they are generally divided into hidden handles and traditional mechanical handles, and most of the traditional mechanical handles are externally pulled handles. The externally pulled handle generally consists of a base, a handle body, a balance weight, and a balance return torsion spring. The balance weight is fixed on the base with the balance return torsion spring, and the handle body is installed on the balance weight. Under normal circumstances, under the action of the balance return torsion spring, the handle body has a tendency to fit the vehicle door, thus playing a role in fixing the handle and the vehicle door. However, at present, this locking mechanism of the balance weight - balance return torsion spring can only meet the safety requirements of a safety acceleration of, for example, 30g (g is the acceleration due to gravity). When the vehicle door is laterally impacted, the acceleration generated by the impact force can reach more than 100g. The balance return torsion spring will not be able to ensure that the handle fits the vehicle door, and the vehicle door will open accidentally, causing an accident.
[0003] In the related art, by adjusting the torque relationship between the balance weight and the handle body, the theoretical calculation requirements of a safety acceleration greater than 30g are met to ensure that the handle body functions normally when an accident occurs and to avoid the situation of the vehicle door opening automatically as much as possible. However, this kind of setting requires complex calculations to obtain a relatively accurate configuration, and affected by complex factors such as the collision object, collision angle, collision part, collision speed, the vehicle side, and the internal structure, the method in the related art cannot meet the inertial torque situations generated in the above various cases, and the reliability is relatively low.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments.

[0056] As the styles of car door handles are increasing, they are generally divided into hidden handles and traditional mechanical handles, and most of the traditional mechanical handles are externally pulled handles.
[0057] Figure 1 is a schematic structural view of an external car door handle in the related art; Figure 2 is a schematic view of the force on the external car door handle when the car door is laterally impacted in the related art.
[0058] Refer to Figure 1 and Figure 2 As shown, the externally pulled handle generally consists of a base 11, a handle body 12, a balance weight 13 and a balance return torsion spring 14. The balance weight 13 is fixed on the base 11 with the balance return torsion spring 14, and the handle body 12 is installed on the balance weight 13. Under normal circumstances, under the action of the balance return torsion spring 14, the handle body 12 has a tendency to fit against the car door, thus playing a role in fixing the handle and the car door. However, at present, this locking mechanism of the balance weight 13 - balance return torsion spring can only meet the safety requirement of 30g (g is the acceleration due to gravity), and when the car door is laterally impacted, the acceleration generated by the impact force can reach more than 100g. The balance return torsion spring will not be able to ensure that the handle fits against the car door, and the car door will open accidentally, causing an accident.
[0059] In the related art, by adjusting the torque relationship between the balance weight 13 and the handle body 12 to meet the theoretical calculation requirements of an acceleration greater than 30g, to ensure that when an accident occurs, the function of the handle body 12 is normal and the situation of the car door automatically opening is avoided as much as possible. However, this kind of setting requires complex calculations to obtain a more accurate configuration, and affected by complex factors such as the collision object, collision angle, collision part, collision speed, the side of the car and the internal structure, the method in the related art cannot meet the inertial torque situations generated in the above various cases, and the reliability is relatively low.
[0060] Figure 3 is a schematic structural view of an external car door handle provided by an embodiment of the present application; Figure 4 is a front view schematic of an external car door handle (the first part 230 and the second part 240, the rotating shaft 600) provided by an embodiment of the present application;Figure 5 Yes Figure 3 is a schematic exploded view of the structure of the outside door handle in
[0061] See Figure 3 , Figure 4 and Figure 5 As shown in
[0062] and
[0063] , an embodiment of the present application provides an outside door handle, which may include a mounting housing 400, a handle body 200, and a transmission member 500.
[0064] The mounting housing 400 is disposed on the vehicle door; the handle body 200 is rotatably disposed on the mounting housing 400 through a connecting member, and the handle body 200 can rotate about an axis 601; the transmission member 500 is movably disposed in the mounting housing 400, and the transmission member 500 is connected to the door lock. The transmission member 500 can be driven by the handle body 200 to pull the door lock to unlock; wherein, the handle body 200 includes a first part 230 and a second part 240 located on both sides of the axis 601; the first part 230 is configured to generate a first torque about the axis 601 relative to the acceleration of the outside / inside of the vehicle door, and the second part 240 is configured to generate a second torque about the axis 601 relative to the acceleration of the outside / inside of the vehicle door; the directions of the first torque and the second torque are the same.
[0065] It can be understood that the mounting housing 400 is embedded in the vehicle door, the outer side of the mounting housing 400 facing the vehicle door is flush with the outer side of the vehicle door, and the mounting housing 400 can be fixed in the vehicle door by means of threaded connection or welding, etc. The mounting housing 400 is mainly used to support the installation of the handle body 200 and the transmission member 500.
[0066] When a side collision occurs, the installation housing 400 moves with the door under the action of the door pulling force, while the handle body 200 moves in the opposite direction to the door movement under the action of inertia force. Since the handle body 200 in this example is divided into two parts by the axis 601, therefore, when a side collision occurs, the first part 230 will generate a first moment around the axis, and the second part 240 will generate a second moment around the axis, and the directions of the first moment and the second moment are the same. If the position of the axis 601 is set appropriately, for example, when the handle body 200 is evenly divided into the first part 230 and the second part 240, the magnitudes of the first moment and the second moment are the same, which will greatly improve the stability of the handle body 200 and make it safer. Of course, if the axis 601 slightly deviates towards the first part 230 or the second part 240, and the first moment and the second moment cancel out part of each other, it can still make the rotational moment of the handle body 200 itself tend to be balanced, and the handle body 200 is more stable and reliable when subjected to a side impact compared to the related art.
[0067] In the embodiment of the present application, the handle body 200 is divided into a first part 230 and a second part 240 by its own rotation axis 601. When a side impact occurs on the door, both the first part 230 and the second part 240 will generate two moments around the axis 601, and the directions of the two moments are the same, thereby making the first part 230 and the second part 240 of the handle body 200 stable relative to the axis, making the handle body 200 itself tend to be in a balanced state, reducing the risk of the door automatically opening, and improving the reliability and safety of the handle body 200.
[0068] Figure 6 is Figure 3 a schematic diagram of the handle in the closed state of the outside door handle of the vehicle in Figure 7 a schematic diagram of the force on the outside door handle (the first part and the second part) of the vehicle when the door is subjected to a side impact in the present application; Figure 8 is Figure 6 a schematic diagram of the back of the outside door handle when the handle is in the closed state in Figure 9 is Figure 8 a partial enlarged schematic diagram of area A in
[0069] Referring to Figure 4 as shown, in some embodiments, the first part 230 includes a first side wall away from the axis 601, and the second part 240 includes a second side wall away from the axis 601; the ratio a / b of the distance a from the axis 601 to the first side wall to the distance b from the axis 601 to the second side wall is between 0.25 - 4.
[0070] It can be understood that the handle body 200 in the present application can be an upward-opening handle. Specifically, the handle body 200 is a plate-like structure adapted to the opening of the mounting housing 400. The connecting member forms an axis 601 during the rotation of the handle body 200, thereby dividing the plate-like mechanism into a first part 230 and a second part 240 that are distributed vertically, horizontally, or diagonally. Taking the vertical distribution as an example, in some embodiments, when the outer door handle is installed on the door, the axis 601 extends in the horizontal direction, the first part 230 is located above the axis 601, the second part 240 is located below the axis 601, and b > a. Refer to Figure 4 As shown, then, the distance from the axis 601 to the uppermost end of the first part 230 is a, and the distance from the axis 601 to the lowermost end of the second part 240 is b. The ratio of a to b can reflect whether the position of the axis 601 is biased upward, downward, or centered. If it is centered, then a / b = 1; if it is biased downward, then a / b can be 2; if it is biased upward, then a / b can be 0.5.
[0071] It should be noted that according to people's habit of opening the door, more space needs to be reserved for the lower part of the upward-opening handle, that is, the second part 240, to facilitate the hand to hold and apply force to open the door. Therefore, the position of the axis 601 should be biased upward, and a / b can be 0.5, 0.6, 0.7, etc. This setting not only facilitates people to open the door but also can optimize the rotational torque at both ends of the handle body 200, making the handle body 200 itself in a state of tending to be balanced.
[0072] In some other embodiments, when the outer door handle is installed on the door, the axis 601 extends in the vertical direction, the first part 230 is located on the left side of the axis 601, the second part 240 is located on the right side of the axis 601, and b > a. It can be understood that this door can also be a left-opening or right-opening handle. Similarly, more space is reserved for the hand to hold and apply force. The axis 601 can be set to be biased to the left, that is, along the horizontal direction, the length of the second part 240 is greater than the length of the first part 230, and a / b can be 0.5, 0.6, 0.7, etc. This setting can optimize the rotational torque at both ends of the handle body 200, making the handle body 200 itself in a state of tending to be balanced and reducing the risk of the door opening automatically.
[0073] Refer to Figure 4 and Figure 5 As shown, in some embodiments, the mounting housing 400 is configured with a receiving cavity 410. The receiving cavity 410 has an opening facing the outside of the door, and the handle body 200 is used to cover the opening; the connecting member includes a rotating shaft 600. Both ends of the rotating shaft 600 are respectively disposed on the opposite inner walls of the mounting housing 400, and the axial direction of the rotating shaft 600 coincides with the axis 601.
[0074] It can be understood that the rotation axis 600 can be located at the middle position of the accommodation cavity 410, which facilitates the rotation of the handle body 200 in the accommodation cavity 410 and is beneficial to opening the vehicle door. Additionally, preferably, the rotation axis 600 is located at a position slightly above the middle of the accommodation cavity 410, that is, the rotation axis 600 divides the handle body 200 into an upper half and a lower half (the first part 230 and the second part 240). Among them, the length of the upper half is less than the length of the lower half, so that the moment of the lower half is greater than the moment of the upper half. This can not only achieve the above-mentioned state where the handle body 200 itself is in a balanced state, but also achieve the purpose of saving effort by using the lever principle during the process of turning the handle body 200.
[0075] As Figure 17 shown, in some embodiments, the transmission member 500 is rotatably disposed on the outer surface of the bottom wall of the mounting housing 400; a limiting hole 420 is formed in the bottom wall of the mounting housing 400, and the limiting hole 420 is used for a part of the handle body 200 to pass through and abut against the transmission member 500 during the unlocking process.
[0076] It can be understood that a limiting hole 420 is provided on the bottom wall of the accommodation cavity 410 (i.e., the bottom wall of the mounting housing 400) ( Figure 3 and Figure 5 not shown in the figure). Exemplarily, the limiting hole 420 can be an oblong hole, and the length direction of the limiting hole 420 extends along the length direction or the width direction of the accommodation cavity 410. For example, when the axis 601 extends in the horizontal direction and the handle body 200 rotates around the axis 601, the limiting hole 420 can extend along the width direction of the accommodation cavity 410; correspondingly, when the axis 601 extends in the vertical direction and the handle body 200 rotates around the axis 601, the limiting hole 420 can extend along the length direction of the accommodation cavity 410. It should be noted that the width direction of the accommodation cavity 410 can be referred to as Figure 3 and Figure 5 shown by the y-direction in the figure, and the length direction can be referred to as Figure 3 and Figure 5 shown by the x-direction in the figure.
[0077] The handle body 200 is hinged to the side wall of the accommodation cavity 410 through the rotation axis 600, and the end of the handle body 200 can rotate in the direction towards or away from the accommodation cavity 410 under the action of an external force. Additionally, at least a part of the handle body 200 can extend out of the accommodation cavity 410 from the limiting hole 420, that is, to the side of the bottom wall of the mounting housing 400 facing away from the accommodation cavity 410, and at least a part of the handle body 200 moves along the length direction of the limiting hole 420. It should be noted that the setting direction of the handle body 200 corresponds to the length direction of the limiting hole 420 to ensure that at least a part of the handle body 200 can move along the length direction of the limiting hole 420 when the handle body 200 rotates. Exemplarily, in some examples, the width direction of the accommodation cavity 410 (which can be referred to asFigure 3 is arranged vertically as shown in the y - direction in Figure 3 and the length direction of the limiting hole 420 located on the bottom wall is also arranged vertically. The handle body 200 is rotatably arranged in the accommodation cavity 410, and the handle body 200 can rotate around a rotation axis extending along the length direction of the accommodation cavity 410 (the length direction can be referred to as
[0078] shown in the x - direction in
[0079] The transmission member 500 is arranged on the outer surface of the bottom wall and at least part of the handle body 200 can drive the transmission member 500 to rotate.
[0080] In some examples, the transmission member 500 selectively contacts at least part of the handle body 200 to drive the transmission member 500 to rotate. One end of the transmission member 500 is connected to the door lock of the vehicle door. The transmission member 500 pulls the door lock to open the vehicle door. Exemplarily, the transmission member 500 can be arranged on the side of the bottom wall facing away from the accommodation cavity 410 through a rotating shaft, and the transmission member 500 rotates closely against the outer surface of the bottom wall. The end of the transmission member 500 away from the rotating shaft is connected to a cable, so that the transmission member 500 can pull the cable to move during rotation.
[0081] In some other examples, different from the above - mentioned embodiments, the transmission member 500 and at least part of the handle body 200 can be connected through a connecting member, such as a steel wire rope, so that the handle body 200 drives the transmission member 500 to rotate during rotation.
[0082] In addition, the upper end of the transmission member 500 can be located below at least part of the handle body 200, and part of the handle body 200 can abut against the transmission member 500 during rotation, thereby driving the transmission member 500 to rotate. Or, the lower end of the transmission member 500 can also be located above at least part of the handle body 200, and part of the handle body 200 can abut against the transmission member 500 during rotation.
[0083] It can be understood that when the relative position relationship between the transmission member 500 and at least a part of the handle body 200 changes, in order to ensure that a part of the handle body 200 can abut against the transmission member 500 during rotation, it is necessary to adaptively adjust the rotation direction of the handle body 200. For example, when the upper end of the transmission member 500 is located below at least a part of the handle body 200, the handle body 200 needs to rotate clockwise; when the lower end of the transmission member 500 is located above at least a part of the handle body 200, the handle body 200 needs to rotate counterclockwise.
[0084] As Figure 6 and Figure 8 shown, in some embodiments, the handle body 200 includes a handle cover 210 and a toggle 220. The handle cover 210 is adapted to the opening of the receiving cavity 410. The toggle 220 is disposed on the side of the handle cover 210 facing the inside of the vehicle door, and the toggle 220 protrudes from the handle cover 210. The handle cover 210 is disposed on the mounting housing 400 through a rotating shaft 600. The toggle 220 passes through the limiting hole 420 and extends to the outside of the mounting housing 400. The toggle 220 is used to toggle the transmission member 500 to rotate during the unlocking process.
[0085] It can be understood that the toggle 220 protrudes from the handle cover 210, the handle cover 210 is movably disposed in the receiving cavity 410, and the toggle 220 can pass through the limiting hole 420 and extend to the outside of the receiving cavity 410 to contact the transmission member 500. Additionally, by way of example, the shape of the handle cover 210 is the same as the orthographic projection shape of the receiving cavity 410, and the size of the handle cover 210 is smaller than the size of the orthographic projection contour of the receiving cavity 410, so as to ensure that the handle cover 210 can rotate in the receiving cavity 410. Additionally, the surface of the toggle 220 facing the transmission member 500 can be a curved surface to ensure that when the toggle 220 contacts the transmission member 500, it is surface-to-surface contact, increasing the contact area between the two and avoiding damage to the toggle 220.
[0086] As Figure 9 shown, in some embodiments, the transmission member 500 includes a crank 510 and a convex block 520. One end of the crank 510 is rotatably connected to the mounting housing 400, and the other end of the crank 510 is connected to the lock body through a cable. The convex block 520 is fixedly connected to the crank 510. During the unlocking process, the convex block 520 is used to abut against the toggle 220.
[0087] It can be understood that the length of the crank 510 can be adjusted according to requirements and will not be limited here. In one example, the upper surface of the convex block 520 abuts against the lower surface of the toggle 220. Corrugations can be provided at the position where the convex block 520 and the toggle 220 abut to increase the friction between the two and ensure the stability of unlocking.
[0088] When the handle body 200 rotates, the shifting block 220 moves along the length direction of the limiting hole 420. The shifting block 220 abuts against the convex block 520, and the convex block 520 rotates following the shifting block 220. During the rotation, the convex block 520 drives the crank 510 to rotate. During the rotation of the crank 510, the cable is pulled, and the cable pulls the door lock, thereby opening the car door.
[0089] As Figure 5 shown, in some embodiments, the outer door handle of the vehicle further includes a return torsion spring 700. The return torsion spring 700 is sleeved on the rotating shaft. One end of the return torsion spring 700 is limited to the inner wall of the handle cover 210, and the other end of the return torsion spring 700 is limited to the mounting housing 400.
[0090] It can be understood that one end of the return torsion spring 700 abuts in the accommodating cavity 410, and the other end abuts against the upper half part (the first part 230) of the handle body 200, that is, the part with a smaller length of the handle body 200, ensuring that the handle cover 210 can be in the accommodating cavity 410 without being acted by an external force, and the outer surface of the handle cover 210 is flush with the outer surface of the vehicle door, achieving the purpose of hiding the outer door handle of the vehicle. After the handle cover 210 is rotated to open the car door, the handle cover 210 protruding from the car door surface will automatically return to the accommodating cavity 410 under the action of the return torsion spring 700.
[0091] As Figure 5 shown, in some embodiments, the outer door handle of the vehicle further includes a damper 800. The damper 800 is sleeved on the rotating shaft. The damper 800 can slow down the rotation speed of the handle body 200 and improve the rotation feel and return quality of the handle body 200.
[0092] Figure 10 is a schematic diagram of the first state of the outer door handle when opening the car door; Figure 11 is a schematic diagram of the second state of the outer door handle when opening the car door; Figure 12 is Figure 11 a schematic diagram of the back of the outer door handle in Figure 13 is Figure 12 a partial enlarged schematic diagram of area B in Figure 14 is a schematic diagram of the third state of the outer door handle when opening the car door; Figure 15 is a schematic diagram of the fourth state of the outer door handle when opening the car door; Figure 16 is Figure 15 a schematic diagram of the back of the outer door handle in Figure 17 is Figure 16 a partial enlarged schematic diagram of area C in
[0093] Referring to Figure 10As described above, when no force is applied to the handle body 200, the outside door handle is in the first state, and the outer surface of the handle cover 210 is flush with the side wall surface of the mounting housing 400 (i.e., flush with the door surface, and the door surface is not shown in the figure). When opening the door, first, a force F1 needs to be applied to the upper half (the first part 230) of the handle cover 210, and the handle cover 210 rotates around the rotation axis 600 into the receiving cavity 410 of the mounting housing 400 until the slider 220 of the handle body 200 contacts the lug 520 of the transmission member 500. This is the first process, and the outside door handle reaches the second state. It should be noted that as Figure 10 shown, the force F1 is a pressure on the handle cover 210. During the rotation of the handle body 200, the first process is an idle stroke, and the slider 220 of the handle body 200 does not exert a force on the lug 520 of the transmission member 500, and the angular change of the handle cover 210 is 16.5°. A schematic diagram of the second state of the outside door handle is referred to Figures 11 to 13 shown. At this time, the handle cover 210 is inclined at a certain angle, and at this time, the slider 220 does not contact the crank 510 of the transmission member 500 for the time being.
[0094] Refer to Figure 14 shown, and continue to apply a force F2 to the lower half (the second part 240) of the handle cover 210 of the handle body 200. At this time, the outside door handle is in the third state. Under the action of the force F2, the handle cover 210 continues to rotate around the rotation axis 600. During the rotation process, the slider 220 on the handle body 200 gradually contacts the lug 520 of the transmission member 500 and drives the lug 520 to rotate. The lug 520 drives the crank 510 to rotate, and the crank 510 then pulls the cable to rotate, and the cable pulls the door lock to open the door. At this time, the outside door handle is in the fourth state. A schematic diagram of the outside door handle in the fourth state is referred to Figure 16 and 17 shown.
[0095] When the door opening action is completed and the force F2 is removed, the handle cover 210 returns to the first state under the action of the return torsion spring 700, that is, the outer surface of the handle cover 210 is flush with the outer surface of the door, achieving the purpose of aesthetics.
[0096] In a second aspect, an embodiment of the present application provides an automobile, including an outside door handle, a door, and a gasket 900 as in the first aspect. Among them, the outside door handle is fixedly arranged on the door for conveniently opening or closing the door; the gasket 900 is arranged between the side wall of the receiving cavity 410 of the outside door handle and the door to prevent rainwater from seeping in from the connection between the outside door handle and the door.
