Description

Technical Field

[0001] The invention relates to the technical field of automobile parts, in particular to a novel automobile electric handle. Background Art

[0002] At present, most car door handles are exposed and convex. On the one hand, the design needs to consider that the shape of the car door handle needs to match the side of the car body to ensure a good appearance, which causes many limitations; on the other hand, since the outer door handle is exposed as a whole, the inner and outer sides of the outer door handle are easily contaminated, and the driver's hands are easily dirty when opening the door. In addition, the convex outer door handle not only destroys the side appearance of the entire vehicle, but also causes a certain amount of wind resistance, increases the driving resistance of the car, and increases wind noise. For this reason, many manufacturers have improved the handle structure and manufactured retractable hidden handles.

[0003] Since the position of the hidden handle needs to be changed and involves a dual-path structure of electric and mechanical, compared with the traditional fixed handle, the number of parts increases and the structure is much more complicated. In actual use, the existing hidden handle still has many defects. For example: 1. The electric structure is complex, with many parts and components, high cost, low product reliability and structural limitations, making assembly difficult. The failure rate is high during actual use, resulting in a decrease in the overall reliability of the handle; 2. The current retractable hidden handle has many parts and therefore many openings, resulting in poor air tightness of the handle; 3. The current hidden handles generally have three position states, namely, an initial hidden state retracted into the door, a pre-deployed state extended outside the door, and a fully open state when the door is opened. The handle body is generally switched from the initial hidden state to the pre-deployed state by an electric actuator or manually. At this time, the user continues to pull the handle body to switch to the fully open state, thereby unlocking the door lock and opening the door; however, in the pre-deployed state, due to the action of the reset assembly, the handle body always has a tendency to retract, which may cause hand pinching if not careful, so a state retention structure is urgently needed to prevent the handle body from retracting. Summary of the invention

[0004] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a novel electric handle for an automobile.

[0015] When the handle body is in the initial hidden state, the driving mechanism contacts and abuts against the driving area, and the driving mechanism is started and can drive the transmission cam to rotate;

[0016] When the handle body is in the pre-expanded state, the driving mechanism contacts and abuts against the self-locking area, and the guide track curved surface contacts and abuts against the conversion arm, thereby making the handle body evenly stressed and preventing the handle body from retracting.

[0017] Preferably, the driving mechanism has a telescopic shaft; when the telescopic shaft is located in the driving zone, the driving zone and the end surface of the telescopic shaft form surface-to-surface contact; when the telescopic shaft is located in the self-locking zone, the self-locking zone and the end surface of the telescopic shaft form surface-to-surface contact.

[0018] Preferably, a plurality of supporting ribs are protruding from the handle base, and the supporting ribs correspond to the transmission cam, the conversion arm and the unlocking arm one by one and abut against each other.

[0021] Preferably, a gear damper is provided on the handle base, and a gear portion cooperating with the gear damper is provided on the conversion arm.

[0022] Preferably, a transmission hole is provided on the conversion arm, a transmission arm is protruding from the handle body, and the transmission arm is inserted into the transmission hole.

[0023] Preferably, a reset assembly is further included for resetting the handle body to an initial hidden state; the reset assembly includes a front torsion spring for resetting the handle body, a cam torsion spring for resetting the transmission cam, and a rear torsion spring for resetting the unlocking arm.

[0048] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] Reference Figure 1 to Figure 15 , a new type of automobile electric handle, comprising:

[0050] A handle body 1 is arranged flush with the outer surface of the vehicle door 2, and the handle body 1 has at least an initial hidden state retracted into the vehicle door 2, a pre-expanded state extended out of the vehicle door 2, and a fully opened state when the vehicle door 2 is opened; a handle base 3 is installed in the vehicle door 2, and the handle body 1 is installed in the handle base 3; a driving mechanism 30, which is used to provide driving force; and further includes:

[0051] A transmission cam 4, which is rotatably connected to the handle base 3 and driven by the driving mechanism 30; a conversion arm 5, which is rotatably connected to the handle base 3, is transmission-connected to the handle body 1, and is also contactably connected to the transmission cam 4 and can be driven by the transmission cam 4; an unlocking arm 6, which is movably arranged on the handle base 3, and is contactably connected to the conversion arm 5 and can be driven by the conversion arm 5 to realize the unlocking function of the car door 2 lock; the transmission cam 4 has a guide track curved surface 7 on the side close to the conversion arm 5, and the guide track curved surface 7 is contactably connected to the conversion arm 5.

[0052] After the handle body 1 switches from the initial hidden state to the pre-expanded state, in order to balance the force on the handle body 1 so as to autonomously and continuously maintain the pre-expanded state, a feasible preferred structure is provided in the present embodiment, specifically: a driving groove 8 matching the driving mechanism 30 is provided on the side of the transmission cam 4 close to the driving mechanism 30, and the driving groove 8 has driving areas 9 and self-locking areas 10 of different shapes; wherein, when the handle body 1 is in the initial hidden state, the driving mechanism 30 contacts and abuts against the driving area 9, and the driving mechanism 30 is started and can drive the transmission cam 4 to rotate; in addition, when the handle body 1 is in the pre-expanded state, the driving mechanism 30 contacts and abuts against the self-locking area 10, and at the same time, the guide track curved surface 7 contacts and abuts against the conversion arm 5, so that the force on the handle body 1 is evenly distributed and the handle body 1 is prevented from retracting. More specifically, the driving mechanism 30 has a telescopic shaft 31; when the telescopic shaft 31 is located in the driving area 9, the driving area 9 forms a surface-to-surface contact with the end surface of the telescopic shaft 31, so that when the driving mechanism 30 is started, the force of the telescopic shaft 31 pushing forward can be more efficiently transmitted to the transmission cam 4 by the surface-to-surface contact, so that the transmission cam 4 rotates; when the telescopic shaft 31 extends forward a certain distance, that is, leaves the driving area 9 and enters the self-locking area 10, at this time, the handle body 1 is also switched from the initial hidden state to the pre-deployed state through the action of the transmission cam 4; when the telescopic shaft 31 is located in the self-locking area 10, the self-locking area 10 forms a surface-to-surface contact with the end surface of the telescopic shaft 31, at this time, the various forces exerted on the transmission cam 4 and the conversion arm 5 are balanced, thereby preventing the handle body 1 from retracting, forming a position self-locking effect, so that it can be maintained in the pre-deployed state.

[0053] Preferably, the angle formed by the two side walls of the self-locking area 10 differs from the angle formed by the two side walls of the driving area 9 by 45 degrees (actually not limited to this angle, as long as the self-locking area 10 and the telescopic shaft 31 can be interlocked with each other), that is, the angle difference just offsets the rotation angle of the transmission cam, so that the two side walls of the self-locking area 10 can form surface-to-surface contact with the end face of the telescopic shaft 31 to achieve force balance in all directions.

[0054] In this embodiment, a plurality of support ribs 11 are convexly provided on the handle base 3, and the support ribs 11 correspond to and abut against the transmission cam 4, the conversion arm 5 and the unlocking arm 6. The arrangement of a plurality of support ribs 11 can support the transmission cam 4, the conversion arm 5 and the unlocking arm 6, so that these components will not deviate in unnecessary directions during the rotation process, so that they always remain on their respective planes, thereby making their respective rotation movements more stable and reliable. At the same time, the support ribs 11 are thinned to reduce the friction between the support ribs 11 and the transmission cam 4, the conversion arm 5 and the unlocking arm 6, so that the operation of each accessory is smoother, and the failure rate can be effectively reduced and the service life can be extended.

[0055] Regarding the coordination and transmission relationship between the conversion arm 5 and the unlocking arm 6, in short, as long as the two can contact, the force transmission can be achieved. In the prior art, the defects that are more likely to occur during the coordination process are: first, the coordination angle or connection relationship is not good, which makes the force transmission not efficient enough; second, it is easy to cause slippage, abnormal noise, bounce and other faults; third, the force transmission in the positive direction is reliable, but the effect may not be good when resetting in the reverse direction. In order to solve the above defects, in this embodiment, the conversion arm 5 is provided with a first transmission hook 12, and the unlocking arm 6 is provided with a second transmission hook 13, and the first transmission hook 12 can be offset with the second transmission hook 13 and realize the transmission of the conversion arm 5 and the unlocking arm 6. Preferably, the first transmission hook 12 is integrally formed with the conversion arm 5, and the second transmission hook 13 is integrally formed with the unlocking arm 6, which is simpler and more efficient in production and manufacturing, and the strength of the components itself is higher; when the two are coordinated, an interlocking relationship can be formed, so that slippage, abnormal noise, bounce and other faults will not be eliminated, so that the transmission of bidirectional force is sufficiently reliable and stable.

[0056] After the door 2 is opened, the user releases the handle body 1, and the handle can automatically reset under the action of the reset component. During the reset process, due to the action of elastic force and / or inertial force, if not handled, it may cause violent collisions between various components and produce various abnormal noises, or even damage to components, resulting in a shortened life of the components; and if the various components are not limited, they may move excessively, affecting the normal use of the next cycle. In order to solve the above-mentioned defects, a limit block 14 is provided on the handle base 3, and a buffer pad 15 is also provided on the limit block 14, and the unlocking arm 6 can abut against the buffer pad 15. Through the setting of the limit block 14, the unlocking arm 6 can abut against each other when resetting to achieve the limiting function; and through the setting of the buffer pad 15, when the unlocking arm 6 contacts the limit block 14, an effective buffering effect is provided, abnormal noise is eliminated, and the impact force during collision is reduced, thereby playing a protective effect on the corresponding components.

[0057] In this embodiment, the handle base 3 is provided with a gear damper 16, and the conversion arm 5 is provided with a gear portion 17 that cooperates with the gear damper 16. With the provision of the gear damper 16, the related accessories are more orderly during operation, and the user can have a better hand feeling when operating the handle body 1, while also playing an effective buffering and protective role for each accessory.

[0058] In this embodiment, a transmission hole 18 is provided on the conversion arm 5, and a transmission arm 19 is convexly provided on the handle body 1, and the transmission arm 19 is inserted into the transmission hole 18. The transmission function of the handle body 1 and the conversion arm 5 is realized by plugging and matching the transmission arm 19 and the transmission hole 18; and the plugging and matching is a non-fixed connection, so the corresponding accessories are subjected to relatively gentle force, and are more firm and reliable in terms of use strength.

[0059] When the user releases the handle body 1 after opening the car door 2, the handle body 1 is generally required to be able to reset automatically. Since the component composition and connection relationship in the present invention are different from the component composition of hidden handles on the market, in short, the connection between the various components in the present invention adopts a fixed transmission connection, so it is necessary to set a one-to-one reset structure for each accessory to achieve the corresponding function, and such a structure does not exist in the prior art. To this end, the present embodiment provides a feasible preferred scheme, specifically: it also includes a reset component for resetting the handle body 1 to the initial hidden state; the reset component includes a front torsion spring 20 for resetting the handle body 1, a cam torsion spring 21 for resetting the transmission cam 4, and a rear torsion spring 22 for resetting the unlocking arm 6. Among them, the handle body 1 is rotatably connected to the handle base 3 through a first rotating shaft 23, and the front torsion spring 20 is sleeved on the first rotating shaft 23; the handle base 3 is convexly provided with a second rotating shaft 24, and the transmission cam 4 is rotatably connected to the handle base 3 through the second rotating shaft 24, the handle base 3 is provided with a first cam torsion spring half groove 25, and the transmission cam 4 is provided with a second cam torsion spring half groove 26, and the first cam torsion spring half groove 25 and the second cam torsion spring half groove 26 cooperate to form a complete The cam torsion spring groove is a complete cam torsion spring groove, and the cam torsion spring 21 is arranged in the cam torsion spring groove; the handle base 3 is provided with a third rotating shaft 27, and the unlocking arm 6 is rotatably connected with the handle base 3 through the third rotating shaft 27; the handle base 3 is provided with a first rear torsion spring half groove 28, and the unlocking arm 6 is provided with a second rear torsion spring half groove 29, and the first rear torsion spring half groove 28 and the second rear torsion spring half groove 29 cooperate to form a complete rear torsion spring groove, and the rear torsion spring 22 is arranged in the rear torsion spring groove. Through the action of the front torsion spring 20, the handle body 1 and the conversion arm 5 can be automatically reset; through the action of the rear torsion spring 22, the unlocking arm 6 can be automatically reset; through the action of the cam torsion spring 21, the transmission cam 4 can be automatically reset. At the same time, each torsion spring is in a relatively unstable state when it is deformed by force. If it is not limited, it is very likely to leave the normal working position, resulting in the reset function cannot be used normally. In this embodiment, the first limiting effect is performed on the torsion spring at the corresponding position through each rotating shaft, and then the second limiting effect is formed on the torsion spring through the setting of each torsion spring groove. Therefore, under the action of the double limiting structure, each torsion spring can have a better working position retention state and can operate reliably for a long time.

[0060] Preferably, the handle body 1 of the present invention has a fourth state, which can be called a manual activation state. That is, when the vehicle is out of power, the drive mechanism 30 cannot be started and used normally, and the transmission cam 4 cannot rotate. At this time, the user needs to manually press the end of the handle body 1 close to the drive mechanism 30 so that the end moves toward the inside of the vehicle body, and at the same time, the other end of the handle body 1 is tilted toward the outside of the vehicle body, that is, the handle body 1 is switched to the pre-deployed state, and then the user continues to pull the handle outward with force until the rear end of the handle body 1 can be extended into the key space, and the key is inserted to unlock the door. Since the transmission cam 4 does not rotate during the manual activation process, compared with the normal situation, the position self-locking function of the handle body 1 in the pre-deployed state cannot be achieved.

[0061] The present invention provides a novel automobile electric handle, and its normal working principle is as follows:

[0062] When the handle body 1 switches from the initial hidden state to the pre-expanded state, the driving mechanism 30 is started to make the telescopic shaft 31 extend forward, and the end face of the telescopic shaft 31 forms a surface-to-surface contact with the driving area 9 in the driving groove 8 to achieve a good transmission effect, and then the telescopic shaft 31 pushes the transmission cam 4 to rotate around the second rotating shaft 24; during the rotation of the transmission cam 4, the contact point between the conversion arm 5 and the guide track curved surface 7 changes, realizing the guiding function, so that the conversion arm 5 rotates according to the predetermined track, so that the handle body 1 connected to the conversion arm 5 rotates around the first rotating shaft 23 and realizes the tilting and swinging function, and the handle body 1 is successfully switched to the pre-expanded state;

[0063] When the handle body 1 is in the pre-expanded state, the end face of the telescopic shaft 31 has left the driving area 9 and entered the self-locking area 10. The self-locking area 10 and the telescopic shaft 31 are in surface contact. At this time, the various forces acting on the transmission cam 4 and the conversion arm 5 are balanced, thereby preventing the handle body 1 from retracting, forming a position self-locking effect, and allowing it to remain in the pre-expanded state for a long time.

[0064] When the handle body 1 switches from the pre-expanded state to the fully opened state, the handle body 1 is already in the pre-expanded position, the tail end of the handle body 1 protrudes and forms a certain angle with the vehicle door 2 to facilitate the hand to reach in, and then the user holds the handle body 1 and gently pulls it outward, the handle body 1 drives the conversion arm 5 to rotate at the same time, so that the first transmission hook 12 and the second transmission hook 13 on the conversion arm 5 abut against each other and realize the transmission effect, so that the unlocking arm 6 changes its position, and then the car door 2 lock matched with the unlocking arm 6 is unlocked, and the user can open the vehicle door 2.

[0065] When the handle body 1 switches from the fully open state to the initial hidden state, the user releases the handle body 1 after opening the door 2. When the handle body 1 is in the fully open state, the telescopic shaft 31 of the driving mechanism 30 will automatically reset first; then the handle body 1 and the conversion arm 5 will automatically reset through the action of the front torsion spring 20; the unlocking arm 6 will automatically reset through the action of the rear torsion spring 22; and the transmission cam 4 will automatically reset through the action of the cam torsion spring 21. Then the handle body 1 is hidden in the handle base 3 and is set flush with the outer surface of the door 2.

[0066] It should be pointed out that the handle structure of the present invention is not limited to the outer handle of the vehicle door 2, but can also be used inside the vehicle or in other scenarios.

[0067] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment according to the technical essence of the invention still falls within the protection scope of the technical solution of the present invention.
