Description

Technical Field

[0001] This application relates to the technical field of automotive parts, and more specifically, to a concealed handle with a collision ejection function. Background Technology

[0002] With the development of the four new trends in automobiles (electrification, connectivity, intelligence, and sharing), users have increasingly higher demands for automotive intelligence. Among these, the demand for and market application of concealed door handles are growing. These handles can automatically pop out or retract, improving the user experience and reducing wind resistance. In existing concealed door handles, during a high-speed collision, the ECU intercepts the signal from the BCM (Body Module) collision sensor and sends a pop-out command to the handle's drive motor. The drive motor then deploys the handle, allowing rescue personnel to use it for assistance. However, this process takes 1-2 seconds. In extreme high-speed collision scenarios, the BCM's power supply may only last about 50ms, insufficient time for the handle's drive motor to deploy, hindering external rescue efforts. Current technology uses an additional capacitor within the concealed door handle to store electrical energy. This capacitor is activated when the airbag system deploys any airbag or detects a collision signal, providing an additional 1-2 seconds of power to the drive motor to deploy the handle in the event of a power outage. However, this increases production costs.

[0003] Invention Patent Content

[0004] To address at least one aspect of the aforementioned problems, the present invention provides a concealed handle with a collision-exploded function, comprising a base, a handle assembly, a drive assembly, an ejection assembly, and an unlocking assembly; the base has a hollow internal structure; an opening is formed on a first side of the base; an arc-shaped slide is formed on the side wall of the base, the arc-shaped slide comprising a first segment and a second segment, the first segment extending along the x-direction and the second segment extending along the y-direction, with a smooth transition between the first segment and the second segment; a baffle parallel to the first side is fixedly connected inside the base near the first side, with installation space left between both ends of the baffle and the inner wall of the base along the x-direction; the handle assembly includes a handle body; the size of the handle body matches the size of the opening, a first fixing seat and a second fixing seat are fixedly connected to both ends of the second side of the handle body, the sizes of the first fixing seat and the second fixing seat match the sizes of the installation spaces at both ends of the baffle, the distance between the first fixing seat and the second fixing seat matches the length of the baffle extending along the x-direction, the first fixing seat is hinged to the base, and a first torsion spring is installed at the hinge; the drive assembly includes a drive member, a first connecting rod and a second connecting rod; the first end of the first connecting rod is connected to the drive member. The system is fixedly connected, with the first connecting rod slidably connected to the inner wall of the base. The second end of the first connecting rod is located within the first section of the arc-shaped slide and slidably connected to the first section of the arc-shaped slide. The first end of the second connecting rod is located within the arc-shaped slide, slidably connected to the arc-shaped slide, and abuts against the second end of the first connecting rod. The second end of the second connecting rod is hinged to the second fixed seat. The pop-out assembly includes a housing, a limiting member, and an elastic member. The outer wall of the housing is fixedly connected to the inner walls of the base on both sides along the z-direction. The elastic member is arranged along the y-direction and passes through the housing. The first end of the elastic member abuts against the baffle. The limiting member passes through the housing. It is slidably connected to the inner wall of the housing, and the first end of the limiting member abuts against the second end of the elastic member; the second end of the limiting member includes a first inclined surface and a second inclined surface, the first inclined surface is located on the side closer to the driving member, the angle between the first inclined surface and the x direction is in the range of 5 to 25 degrees, and the angle between the second inclined surface and the opposite x direction is in the range of 40 to 75 degrees; the unlocking component includes a balance block, the balance block includes a connecting seat and a connecting bar; the connecting seat is rotatably connected to the base, and a pull wire is connected to the connecting seat for connecting to the door lock; the first end of the connecting bar is fixedly connected to the connecting seat, and the connecting bar moves within the second connecting rod.

[0005] With the above technical solution, when the handle is in normal use, the first link is driven by the drive component, and the second end of the first link pushes the second link to slide in the arc-shaped slide. The first link abuts against the limiting component, which compresses the elastic component and supports the second end of the handle body to extend. Then, by rotating the second end of the handle body, the door is unlocked by the pull cable on the balance block. During this process, the first end of the second link gradually moves away from the second end of the first link along the arc-shaped slide. Under the action of the first torsion spring, the first end of the second link gradually moves closer to the second end of the first link along the arc-shaped slide until it abuts. When a door closing signal is given to the door controller, for example, by sending a signal to the door controller through the door lock closing, the door controller will control the drive component to pull back the first link. During this process, the supporting force of the first link on the limiting component gradually decreases, and it helps the first end of the second link to pass over the second inclined surface of the limiting component, so that the handle body retracts into the base. In the event of a collision and power loss to the door, the first end of the second linkage, under the influence of inertia, will jump from the first inclined surface to the second inclined surface. However, due to the larger inclination angle of the second inclined surface, the greater elastic force of the elastic element compared to the first torsion spring, and the lack of assistance from the first linkage, the first end of the second linkage cannot jump over the second inclined surface. This causes the second end of the second linkage to lift up, making it easier for rescue personnel to spot. Rescuers can then unlock the door by rotating the second end of the handle. The pop-out component in the concealed handle of this application has a simple and low-cost structure, enabling the concealed handle to automatically partially open in the event of a collision, facilitating rescue efforts.

[0006] Preferably, the angle between the second inclined surface and the opposite x-direction is between 45 and 60 degrees. Since it is necessary to ensure that, in the event of a collision, the first end of the second link will not jump along the second inclined surface to the first inclined surface without external force, causing the handle to retract, the angle should not be too small. At the same time, it is also necessary to ensure that, after the rescue, under appropriate external force, the first end of the second link will jump along the second inclined surface to the first inclined surface, causing the handle to retract, so the angle should not be too large. Through the above technical solution, the angle between the second inclined surface and the opposite x-direction is preferably between 45 and 60 degrees. This ensures that the handle remains in a semi-open state during a collision and also helps to restore the handle to an appropriate external force after the rescue.

[0007] Preferably, the angle between the first inclined surface and the x-direction is in the range of 5 to 15 degrees. This is because, in the event of a collision, the first end of the second link can jump from the first inclined surface to the second inclined surface, and in normal use but with the door power off, if a passenger presses the first end of the first side of the handle body, causing the second end of the handle body to lift up, and the passenger continues to pull the second end of the handle body, the first end of the second link can also jump from the first inclined surface to the second inclined surface; therefore, the angle should not be too large. At the same time, the path length of the first end of the second link along the first inclined surface should be appropriate, and the dimensions should match those of other structures appropriately; therefore, the angle should not be too small. Through the above technical solution, the preferred angle between the first inclined surface and the x-direction is 5 to 15 degrees. This ensures that the handle remains in a semi-open state in the event of a collision and also contributes to the compact structure and small space occupation of the handle in this application.

[0008] Preferably, the limiting member includes a movable seat and a limiting block; the dimensions of the outer wall of the movable seat match the dimensions of the inner wall of the housing, the movable seat passes through the inner wall of the housing and is slidably connected to the inner wall of the housing, and the first end of the movable seat abuts against the elastic member; the limiting block is a triangular prism structure, and the limiting block includes a first inclined surface, a second inclined surface, and a third inclined surface, the third inclined surface being fixedly connected to the second end of the movable seat. Through the above technical solution, a specific structure of the limiting member is disclosed. As the elastic member compresses and recovers, the movable seat slides within the housing along the direction of movement of the elastic member, driving the limiting block to move along the direction of movement of the elastic member. This achieves the effect of, under normal circumstances, the second connecting rod stably jumping from the first inclined surface to the second inclined surface to extend the handle, and jumping from the second inclined surface to the first inclined surface to retract the handle, and the limiting effect on the second connecting rod in the event of a collision, so that the handle is in a half-open state.

[0009] Preferably, the balance block further includes a slot formed on the connecting seat; an inertial lock is disposed near the slot, the inertial lock including a fixed shaft, a fixed seat, a second torsion spring, and a locking bar; the fixed shaft is fixed to the base; the fixed seat is sleeved on the fixed shaft and rotatably connected to the fixed shaft; the second torsion spring is sleeved on the fixed shaft, one end of the second torsion spring is fixedly connected to the base, and the other end is fixedly connected to the fixed seat; the size of one end of the locking bar matches the size of the slot, and the other end is fixedly connected to the fixed seat. Through the above technical solution, when the car door collides, the inertial force of the inertial lock is greater than the elastic force of the second torsion spring, causing the inertial lock to rotate. The locking bar extends into the slot of the balance block and engages with the slot, preventing the balance block from rotating and preventing the door lock from unlocking and the car door from opening during a collision, thus improving safety.

[0010] Preferably, the unlocking component further includes a micro switch, which is mounted on the connector. With the above technical solution, by setting the micro switch on the connector, under normal use and with power to the door, when the second end of the handle is rotated, the first end of the second linkage drives the balance block to rotate. After detecting the rotation information of the balance block, the micro switch sends an electrical signal to the door controller. Upon receiving the electrical signal, the door controller controls the door lock to unlock. The unlocking method using a micro switch is more sensitive.

[0011] Preferably, the first end of the first connecting rod is trapezoidal; the drive assembly further includes a third connecting rod, which includes a protrusion that abuts against the plane or inclined surface of the first end of the first connecting rod. The first end of the third connecting rod is hinged to the inner wall of the base, and the second end of the third connecting rod is hinged to the first fixed seat. A first torsion spring is provided on the hinge shaft of both the first and second ends of the third connecting rod. Through the above technical solution, the first fixed seat is hinged to the second end of the third connecting rod, and the first end of the third connecting rod is hinged to the base. This achieves the first fixed seat of the handle body being hinged to the base via the third connecting rod. Under normal circumstances, the drive unit drives the first connecting rod, causing the protrusion of the third connecting rod to move along the inclined surface of the first end of the first connecting rod to the plane, thereby pushing the first fixed seat of the handle body. The second end of the first connecting rod pushes the second fixed seat of the handle body by pushing the second connecting rod, thereby causing the handle body to pop out vertically relative to the base. This helps to reduce the Y-axis dimension of the concealed handle to 55mm, making it compatible with more types of car doors.

[0012] Preferably, the handle assembly further includes a sensor and a handle cover; the sensor is installed inside the handle body, and the handle cover covers the first side of the handle body. Through the above technical solution, by setting a sensor inside the handle body, passengers can transmit commands to the door controller via the sensor, and the door controller can control the extension and unlocking of the handle, thereby improving the intelligence level of the handle.

[0013] Preferably, the sensing element is a capacitive sensor or an NFC module. The above technical solution discloses the specific structure of the sensing element. Using a capacitive sensor installed within the handle body allows passengers to drive the handle with their fingerprints; using an NFC module installed within the handle body allows passengers to select an NFC-enabled electronic device to drive the handle; integrating both a capacitive sensor and an NFC module within the handle body allows passengers to select both fingerprints and NFC-enabled electronic devices to drive the handle. Compared to button-driven handles in the prior art, this improves the handle's intelligence and comfort.

[0014] Preferably, an LED module is installed inside the handle body, and the LED module is snapped into the handle body. With this technical solution, when a passenger drives the handle using a sensor, the LED module illuminates under the action of the door controller, providing a reminder to the passenger and enhancing the handle's technological feel and aesthetics.

[0015] The concealed handle with a collision-exploding function of the present invention has the following beneficial effects:

[0016] (1) By setting an elastic element, a housing, a movable seat and a limiting block between the baffle and the first and second links, under normal circumstances, when the handle of this application is pushed out or retracted, the first link will apply pressure to the elastic element through the movable seat, so that the elastic element is compressed, which helps the second link jump from the second inclined surface to the first inclined surface, thus ensuring the daily use of the handle of this application; when a collision occurs, under the action of inertial force, the first end of the second link jumps from the first inclined surface to the second inclined surface, but cannot jump from the second inclined surface to the first inclined surface without the action of external force, so that the handle of this application is in an automatic half-open state, which is convenient for rescue.

[0017] (2) By preferably having an angle of 5 to 15 degrees between the first inclined surface and the x direction, and an angle of 45 to 60 degrees between the second inclined surface and the opposite x direction, it is ensured that the handle remains in a half-open state when a collision occurs, and it is also helpful to restore the handle to an appropriate external force after the rescue is completed. In addition, it helps to make the structure of the handle of this application compact and occupy less space.

[0018] (3) By setting a third link, the handle body pops out vertically relative to the base under the cooperation of the drive unit, the first link, the second link and the third link. On the one hand, the Y-axis dimension of the handle is reduced, expanding the range of door types applicable to the handle of this application; on the other hand, it helps the handle of this application to obtain greater ice-breaking force and reduces the possibility of the hidden handle not popping out when the temperature is low.
