Description

Technical Field

[0001] This invention relates to the field of automotive door handle technology, and in particular to a push-to-unlock car door handle and method. Background Technology

[0002] With the booming development of the new energy vehicle market, innovative vehicle designs are constantly emerging. Hidden door handles offer a more modern and aesthetically pleasing design. They not only make the vehicle's appearance more concise and stylish, but also, because they are concealed within the car door during driving, they enhance the overall integrity of the vehicle's shape, reduce wind resistance, and improve wind noise performance and fuel economy. Currently, most common hidden door handles use a motor-driven system. The working principle is that when the door handle is needed, the user sends an unlock signal using the car key. The motor, through a gear, worm gear assembly, or cam mechanism, causes the handle to pop out of the door or lift one end, allowing the user to manually pull the handle to unlock the door. Alternatively, doors can be unlocked via touch or automatic sensing, but these methods rely on sensors and numerous electronic components, resulting in complex structures and higher costs.

[0003] The inventors discovered that while the aforementioned pull-to-unlock concealed door handle has advantages in some aspects, it also presents usage problems and certain safety hazards in extreme weather conditions. For example, in freezing or high-temperature conditions, when the door handle is frozen and cannot be moved due to low temperatures, when the pop-out component is damaged due to high temperatures, or when pressure is applied to the outside of the door handle, the pop-out mechanism of the concealed door handle may be affected. After the user sends an unlock signal using the car key, the concealed door handle may fail to pop out properly, causing some inconvenience to the user. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a press-type unlocking door handle and method that combines press-type unlocking with pull-type unlocking. By pressing the outer door handle, the car lock is unlocked, adding another door unlocking method. This solves the problem that in extreme conditions such as low temperature, high temperature, or when the door handle is under pressure, the door handle cannot pop out, preventing the user from unlocking and opening the door.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] Firstly, a push-to-unlock car door handle includes:

[0007] The handle housing is used to be embedded in the car door. It has front and rear openings that communicate with the internal cavity. A transmission rod is provided at the middle of the rear side of the handle housing.

[0008] The handle assembly includes an outer door handle and a U-shaped inner door handle. The inner door handle has an outward opening and slides into the internal cavity of the handle housing. A displacement transmission component is provided on the side of the inner door handle away from the outer door handle. A transmission rod passes through the inner door handle and cooperates with the displacement transmission component. A displacement sensor is provided on the displacement transmission component. Pulling the outer door handle outward or pressing it inward will determine different unlocking states based on the displacement sensor to achieve unlocking.

[0009] As a further implementation, the two sides of the inner door handle form a first sliding part and a second sliding part that cooperate with the handle housing, and the inner ends of the first sliding part and the second sliding part are connected by a connecting part to form a U-shaped structure.

[0010] As a further implementation, the outer end of the first sliding part is hinged to one end of the outer door handle, the other end of the outer door handle is connected to one end of the unlocking transmission rod, and the other end of the unlocking transmission rod passes through the second sliding part and is connected to the corresponding unlocking component.

[0011] As a further implementation, a slot is provided on the inner side near the rear end of the outer door handle, and the slot engages and slides with the end of the unlocking transmission rod.

[0012] As a further implementation, a controller is also included. The controller is connected to the displacement transmission component and the displacement sensor. The controller can switch to the press-to-unlock state based on the negative displacement feedback from the displacement sensor, and switch to the pull-to-unlock state based on the positive displacement feedback.

[0013] As a further implementation, the transmission rod is a transmission rack, which passes through the connecting part and the displacement transmission component in sequence, and the sliding engagement between the inner door handle and the handle housing is achieved through the displacement transmission component and the transmission rack.

[0014] As a further implementation, the handle housing is formed by joining two sets of arc-shaped semi-shells. The inner side of the arc-shaped semi-shells is provided with an arc-shaped groove for forming an internal cavity, and a side plate structure is formed on the outer and inner sides of the arc-shaped groove.

[0015] As a further implementation, a transmission rod is provided at the middle position of the rear side plate, and sliding grooves are provided at both ends of the rear side plate for sliding cooperation with the inner door handle.

[0016] As a further implementation, the width of the inner door handle is greater than the width of the handle housing.

[0017] Secondly, a method for operating a push-to-unlock vehicle door handle, characterized in that it employs any of the push-to-unlock vehicle door handles described above, and includes the following steps:

[0018] The user sends an unlock signal to the car via the car key, activating the controller and causing the displacement transmission mechanism to pop out the door handle. If the displacement sensor does not detect any displacement, the controller determines that the door handle cannot pop out normally and shuts down the displacement transmission mechanism. Then, pressing the outer door handle will cause the displacement sensor to detect negative displacement, and the controller will switch to the press-to-unlock state, allowing the door handle to be unlocked by pressing.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The door handle of the present invention combines press-type unlocking and pull-type unlocking. The door lock is unlocked by pressing the outer door handle, which adds another door unlocking method and solves the problem that the door handle cannot pop out and the user cannot unlock and open the door under extreme conditions such as low temperature conditions, high temperature conditions, or when the door handle is under pressure.

[0021] 2. The present invention provides a handle housing with an internal cavity and a sliding groove. The sliding groove enables the door handle to slide against the handle housing. When the door handle needs to be pressed to unlock, the door handle is pressed inward, at which point the internal cavity is exposed. The user can then reach into the internal cavity and apply a pulling force to the front side plate of the arc-shaped semi-shell to unlock the door.

[0022] 3. The displacement transmission component and displacement sensor of the present invention are coupled. The displacement transmission component can realize the pop-out or retraction of the door handle. The displacement transmission component and displacement sensor are connected to the controller. The displacement sensor can detect the forward or reverse displacement of the door handle, thereby the controller can determine different unlocking states. Attached Figure Description

[0033] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0034] Example 1

[0035] In a typical embodiment of the present invention, reference is made to Figures 1-7 As shown, a push-to-unlock car door handle includes a handle housing 6 and a handle assembly that slides with the handle housing 6. The handle assembly includes an outer door handle 1 and an inner door handle 2. The outer door handle 1 is connected to the inner door handle 2, and the outer door handle 1 is also connected to a door unlocking assembly via an unlocking transmission rod 3. Pulling the outer door handle 1 can control the unlocking assembly via the unlocking transmission rod 3 to unlock the car door.

[0036] The handle housing 6 is used to embed into the vehicle door, and has front and rear openings that communicate with the internal cavity 64. A transmission rod is provided at the middle of the rear side of the handle housing 6. The front-rear direction of the handle housing 6 is defined as the side closer to the vehicle door as the front and the side closer to the inside of the vehicle door as the rear.

[0037] The handle assembly includes an outer door handle 1 and an inner door handle 2 arranged in a U-shape. The inner door handle 2 has an outward opening and slides in the internal cavity of the handle housing 6. A displacement transmission component 4 is provided on the side of the inner door handle 2 away from the outer door handle 1. A transmission rod passes through the inner door handle 2 and cooperates with the displacement transmission component 4. A displacement sensor 5 is provided on the displacement transmission component 4. Pulling outward or pressing inward on the outer door handle 1 will determine different unlocking states based on the displacement sensor 5 to achieve unlocking.

[0038] like Figure 2 and Figure 6 As shown, the inner door handle 2 has a first sliding portion 21 and a second sliding portion 22 on both sides that cooperate with the handle housing. The inner ends of the first sliding portion 21 and the second sliding portion 22 are connected by a connecting portion 24 to form a U-shaped structure. It can be understood that the inner end refers to the end closer to the inside of the door, and the outer end refers to the end closer to the outside of the door.

[0039] The outer door handle 1 is connected to the open end of the inner door handle 2. The outer end of the first sliding part 21 is hinged to one end of the outer door handle 1, and the other end of the outer door handle 1 is connected to one end of the unlocking transmission rod 3. The other end of the unlocking transmission rod 3 passes through the second sliding part 22 and is connected to the corresponding unlocking component.

[0040] Correspondingly, a through hole is provided on the second sliding part 22, and the inner end of the unlocking transmission rod 3 passes through the opening of the second sliding part 22 and connects with the unlocking component inside the door.

[0041] Understandably, the diameter of the through hole on the second sliding part 22 needs to be larger than the diameter of the unlocking transmission rod 3 to allow for some movement. A slot is provided on the inner side near the rear end of the outer door handle 1, which engages and slides with the end of the unlocking transmission rod 3. After the door handle pops out, pulling the outer door handle 1 causes it to rotate relative to the inner door handle 2. The unlocking transmission rod 3 does not interfere with the movement of the outer door handle 1. By pulling the outer door handle 1 outward and then pulling the unlocking assembly via the unlocking transmission rod 3, the door is unlocked.

[0042] The above-mentioned pull-out unlocking is a traditional door handle unlocking method. This embodiment retains this unlocking method for daily unlocking. It is understood that the unlocking component is existing technology and will not be described in detail.

[0043] The inner middle of the connecting part 24 of the inner door handle is provided with a displacement transmission component 4. A displacement sensor 5 is coupled to the displacement transmission component 4. The controller 7 is connected to the displacement transmission component 4 and the displacement sensor 5 through a wire. The controller 7 can switch to the press unlock state according to the negative displacement feedback from the displacement sensor 5, and switch to the pull unlock state according to the positive displacement feedback.

[0044] A through hole 23 is provided in the middle of the connecting part 24. The transmission rod is a transmission rack 61, which passes through the connecting part 24 and the displacement transmission member 4 in sequence. The sliding engagement between the inner door handle 2 and the handle housing 6 is achieved through the displacement transmission member 4 and the transmission rack 61. Specifically, an electric motor is provided inside the displacement transmission member 4. The output end of the electric motor engages with the transmission rack 61 through a gear. When the electric motor is working, the displacement transmission member 4 drives the door handle to move along the direction of the transmission rack 61 and pop outward.

[0045] like Figures 4-6As shown, the handle housing 6 is formed by the joining of two sets of arc-shaped semi-shells 62. The inner side of each arc-shaped semi-shell 62 has an arc-shaped groove for forming an internal cavity 64, and side plates 65 are formed on the outer and inner sides of the arc-shaped groove 64. When a press-type unlocking method is used, as... Figure 5 As shown, press the door handle inward so that the outer door handle 1 is located inside the handle housing 6. At this time, the internal cavity 64 is exposed. By reaching your hand into the internal cavity 64 from the outside of the outer door handle 1, you can directly hold the side panel and apply pulling force to open the car door.

[0046] like Figure 4 As shown, a transmission rack 61 is vertically installed in the middle of the rear side panel, and sliding grooves 66 are provided at both ends of the rear side panel for sliding engagement with the inner door handle 2. The two arc-shaped semi-shells 62 form a contact surface 63 at their ends, and are connected and fixedly connected through the contact surface 63. The fixing method is not limited.

[0047] Understandably, the height of the front panel of each set of arc-shaped semi-shells 62 matches the bottom end of the corresponding slide groove 66, so that the outer door handle 1 and the inner door handle 2 can pop out smoothly. After the two sets of arc-shaped semi-shells 62 are joined, their front panels form a rectangular opening structure, the size of which matches the size of the outer door handle. The width of the slide groove 66 matches the width of the sliding part. The depth of the slide groove 66 matches half the height of the sliding part. Figure 6 As shown, in its natural state, the outer door handle 1 is flush with the outer side of the handle housing 6, the width of the inner door handle 2 is greater than the width of the handle housing 6, and after the door handle pops out, the connecting part 24 is always located on the rear side of the handle housing 6.

[0048] In this embodiment, the outer door handle 1 is 140mm long, 10mm wide, and 30mm high, with its outer surface flush with the exterior of the car door for concealment. The inner door handle 2 corresponds to the outer door handle 1, with an overall length of 140mm, width of 60mm, and height of 30mm. The transmission rack is 80mm long. The displacement unlocking module consists of a displacement transmission component 4, a displacement sensor 5, and a controller 7. The displacement transmission component 4 and the displacement sensor 5 are coupled together, with an overall length of 40mm, width of 20mm, and height of 10mm. The entire module is connected to an external control circuit system. The displacement sensor 5 detects the displacement of the door handle and directly feeds it back to the controller 7. The controller 7 processes the data and directly unlocks or locks the door. The displacement transmission component 4 is controlled by the controller 7 and is responsible for the ejection and resetting of the door handle.

[0049] Displacement sensor 5 detects the door handle's displacement, with positive displacement when it pops out and negative displacement when it's pressed in. The user presses the outer door handle 1 to unlock the door; if the handle cannot pop out, the user can directly press the outer door handle to unlock the car. This helps reduce certain safety hazards.

[0050] When a user wants to unlock the car door, the user can remotely send a vehicle unlock signal via the car key to activate the controller. After receiving the unlock signal, the controller 7 processes it and outputs a control signal to control the displacement transmission component 4 to drive the door handle to pop out. After the door handle pops out, the user can pull the outer door handle 1. The outer door handle 1 drives the connecting rod 3 to unlock the car door. At this time, the user can pull the outer door handle 1 to open the car door.

[0051] If the car is in extreme conditions such as low temperature, high temperature, or pressure on the door handle, the door handle may fail to pop out due to excessive external pressure. In this case, the user can manually press the outer door handle 1, causing it to embed into the inner door cavity module. This will cause the door handle to move the connecting rod 3 deeper into the door, and the connecting rod 3 will then reverse, unlocking the door lock's unlocking component. This method can also unlock the door lock. In summary, the press-type unlocking door handle has two unlocking methods: pulling or pressing the outer door handle 1, which drives the connecting rod 3 to unlock the door lock in either the forward or reverse direction. By setting a corresponding transmission component on the inner end of the connecting rod 3, its forward or reverse unlocking of the door's unlocking component can be achieved. Figure 7 As shown below, the two unlocking methods will be explained in more detail.

[0052] Implementation Method 1: When the car door is normally locked, the controller 7 is in an inactive state, waiting for the user to send an unlock signal. When the user sends an unlock signal using the car key, the controller 7 receives the user's unlock signal and is activated. After system processing, it transmits an electrical signal to the displacement transmission component 4, directly controlling the displacement transmission component 4 to drive the door handle, causing it to be displaced by the displacement transmission component 4 to the predetermined state where the door handle pops out of the car door surface. At this time, the user can directly pull the outer door handle 1 to drive the connecting rod 3 connected behind it. The connecting rod 3 pulls the inner door lock to unlock (traditional unlocking method). Figure 2 As shown.

[0053] Implementation method (2): When encountering external pressure, the car is in a normal locked state. However, due to external pressure on the door handle, i.e., when the door handle is pressed by hand, the entire unlocking state will change. The user uses the car key to send an unlock signal. The car controller 7 receives the unlock signal, processes it, and outputs an electrical signal to the displacement transmission component 4. The displacement transmission component 4 is directly controlled to drive the door handle, so that the door handle is displaced by the displacement transmission component 4 to a certain displacement, i.e., the predetermined door handle pops out of the car door surface. However, when the door handle cannot pop out as in method (1) due to external pressure, the displacement sensor 5 will detect that the displacement change of the inner door handle 2 is zero. At this time, the displacement sensor 5 will send a feedback signal to the control system. After processing, the control system will output an electrical signal to the displacement transmission component 4 again, so that it stops the behavior of driving the door handle and closes the displacement transmission component 4.

[0054] After the above actions, the controller remains active. At this point, the user can manually press the outer door handle 1, causing it to embed into the inner door handle cavity 6. The displacement sensor 4 will detect a negative displacement change in the inner door handle and convert this displacement signal into an electrical signal, transmitting it to the controller. The control system within the controller 7 processes the signal and switches to the user-pressed unlock state. In this state, the control system no longer controls the entire unlocking device and re-enters the inactive state. Because the door handle extends into the inner cavity, it causes the unlocking transmission rod 3 to also extend into the door. The unlocking transmission rod 3 then drives the unlocking component inside the door to unlock. Once the door lock is unlocked, the door handle will stop moving, and the user can then pull the lower side panel of the inner cavity 64 to open the door. Figure 3 As shown.

[0055] Implementation method (3): When another extreme situation is encountered, the car is in a normal locked state, but the door handle is frozen, that is, the door handle is frozen and cannot move at low temperature, the entire unlock state will change. The user uses the car key to send an unlock signal, the car controller 7 receives the unlock signal and activates it, and after the system processes it, it outputs an electrical signal to the displacement transmission component 4, directly controlling the displacement transmission component 4 to drive the door handle, so that it is driven by the displacement transmission component 4 to a certain displacement, that is, the predetermined door handle pops out of the car door surface. However, at this time, the door handle of the vehicle cannot pop out because of the ice, the displacement sensor 5 will detect that the displacement change of the inner door handle 2 is zero. At this time, the displacement sensor 5 will feed back a signal to the control system. After processing, the control system outputs an electrical signal to the displacement transmission component 4 again, so that it stops the behavior of driving the door handle and shuts down the displacement transmission component 4.

[0056] After the above actions, the control system remains active. At this point, the user needs to apply greater pressure to press the icy part outside the outer door handle 1 to break the ice. Then, continue applying pressure to embed the door handle into the inner cavity 6. The displacement sensor 4 will detect a negative displacement change in the inner door handle and convert this displacement signal into an electrical signal, which is then transmitted to the control system. After processing the signal, the control system will enter the user-pressed unlocking state. At this point, the control system no longer controls the entire unlocking device and reverts to the inactive state. Because the door handle extends into the inner cavity, it causes the unlocking transmission rod 3 to also extend into the door. The unlocking transmission rod 3 then unlocks the inner door lock. Once the door lock is unlocked, the door handle will stop moving, and the user can then pull the lower side of the inner cavity to open the door. Figure 3 As shown.

[0057] Implementation Method (4): In another extreme case, the car is in a normally locked state, but due to high temperature or prolonged exposure to sunlight, the door handle displacement transmission component 4 or other devices are damaged, and the door handle cannot move. In this case, the entire unlocking state will change. The user uses the car key to send an unlocking signal. The car control system receives the unlocking signal, processes it, and outputs an electrical signal to the displacement transmission component 4. However, since the displacement transmission component 4 or other devices are damaged at this time, the door handle cannot pop out normally. The displacement sensor 5 will detect that the displacement change of the inner door handle 2 is zero. At this time, the displacement sensor 5 will feed back a signal to the control system. After processing, the control system will output an electrical signal again to the entire unlocking system.

[0058] After the above actions, the control system remains active. At this point, the user needs to manually apply pressure to press the outer door handle 1, causing it to embed into the inner door handle cavity 6. The displacement sensor 4 will detect a negative displacement change in the inner door handle and convert this displacement signal into an electrical signal, which is then transmitted to the control system. After processing the signal, the control system will enter the user-pressed unlocking state. At this point, the control system no longer controls the entire unlocking device and re-enters the inactive (pending) state. Because the door handle extends into the inner cavity, it causes the unlocking transmission rod 3 to also extend into the door. The unlocking transmission rod 3 then unlocks the inner door lock. Once the door lock is unlocked, the door handle will stop moving, and the user can then pull the lower side of the inner cavity to open the door. Figure 3 As shown.

[0059] In a typical embodiment of the present invention, reference is made to Figures 1-7 As shown, a method for operating a push-to-unlock car door handle, using the push-to-unlock car door handle described in Embodiment 1, includes the following steps:

[0060] The user sends an unlock signal to the car via the car key, activating the controller, which then controls the displacement transmission mechanism to pop out the door handle. If the displacement sensor 5 detects a positive displacement, the target positive displacement distance is reached, and the controller determines that the door handle can pop out normally, allowing for external pull-out unlocking. If the displacement sensor 5 does not detect any displacement, the controller determines that the door handle cannot pop out normally, and the controller deactivates the displacement transmission mechanism. The controller then enters a standby state. When the external door handle is pressed, the displacement sensor detects a negative displacement, and the controller switches to press-to-unlock mode, allowing the door handle to be unlocked by pressing.

[0061] By pressing the exterior door handle to unlock the car, an additional door unlocking method is added, solving the problem that the door handle cannot pop out and the user cannot unlock and open the car door under extreme conditions such as low temperature, high temperature, or when the door handle is under pressure.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
