Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, and relates to a concealed exterior door handle and a car door. Background Technology

[0002] With technological advancements and rising aesthetic demands, automobiles are evolving towards simpler lines, greater intelligence, and higher-end features. Traditional manual door handles, limited by structural shape and function, severely impact the overall aesthetics, intelligence, and premium feel of a vehicle. Therefore, automotive door handles are developing towards concealed and intelligent designs.

[0003] Currently, there are many hidden door handles for cars on the market. These hidden door handles generally use a motor to unfold the handle, which is normally hidden, and then pulling the handle unlocks the car door. For example, an invention patent with application number CN2017109195634 discloses a hidden car exterior door handle, and a utility model patent with application number CN2019203504821 discloses a hidden car exterior door handle structure. The structures of the two are quite similar, both using a horizontal quadrilateral folding principle. There are also currently hidden door handles that use a vertical quadrilateral folding and telescopic mechanism.

[0004] However, the structures of these concealed handles are quite complex and the manufacturing costs are relatively high. Furthermore, they are all electric structures, requiring a motor to unfold or retract the outer handle. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a concealed exterior door handle and a car door.

[0006] The objective of this invention can be achieved through the following technical solution: a concealed exterior door handle, comprising:

[0007] A base plate, wherein an opening slot is provided on the base plate, and a hinge seat is provided on one side of the base plate near the opening slot;

[0008] A handle panel, wherein the handle panel is provided with a main shaft, the main shaft is circumferentially fixedly connected to the handle panel, and the main shaft is rotatably connected to the hinge seat;

[0009] The unlocking mechanism includes an unlocking arm, an unlocking force block, and an unlocking traction cable. The unlocking arm is rotatably sleeved on the main shaft. The unlocking force block is circumferentially fixedly connected to the main shaft. The unlocking traction cable is connected to the unlocking arm.

[0010] The main shaft can rotate circumferentially to an initial position or a linked position. When the main shaft is in the initial position, the handle panel is located in the opening slot. When the main shaft rotates from the initial position to the linked position, the unlocking force block moves towards the unlocking arm, and the handle panel separates from the opening slot, thereby exposing the opening slot to form a handle structure for opening the car door. When the main shaft rotates to the linked position, the unlocking force block abuts against the unlocking arm, and when the main shaft continues to rotate past the linked position, the unlocking force block drives the unlocking arm to rotate, thereby pulling the unlocking traction cable.

[0011] Preferably, the device also includes a torsion spring, which is sleeved on the main shaft. One end of the torsion spring is connected to the base plate and the other end is connected to the main shaft. The torsion spring applies a torque to the main shaft to rotate it toward the initial position.

[0012] Preferably, the device also includes a motor, the motor's shaft of which is connected to the main shaft. The main shaft is controlled to rotate from the initial position toward the linkage position and past the linkage position by the forward rotation of the motor to achieve automatic unlocking, or the main shaft is controlled to rotate toward the initial position by the reverse rotation of the motor to achieve automatic reset.

[0013] Preferably, a damper is also fixedly provided on one side of the base plate, and the damper is connected to the main shaft to apply a damping force to the rotation of the main shaft.

[0014] Preferably, the travel area of ​​the main shaft between the initial position and the linkage position is the neutral zone, and the travel area of ​​the main shaft after passing the linkage position is the unlocking zone. When the main shaft rotates in the neutral zone, the unlocking force block separates from the unlocking arm. When the main shaft rotates in the unlocking zone, the unlocking force block and the unlocking arm abut against each other and move synchronously.

[0015] Preferably, the base plate is provided with a limit block, and when the main shaft rotates from the linkage position to the initial position, the unlocking arm is abutted by the limit block and separated from the unlocking force block.

[0016] Preferably, one side of the base plate is covered with a protective shell, and the protective shell covers the handle panel.

[0017] Preferably, the base plate is provided with a fixing block, and a limiting sleeve is installed on the fixing block, and the unlocking traction cable is movably inserted into the limiting sleeve.

[0018] Preferably, the shape and size of the handle panel are adapted to the shape and size of the opening slot, and the handle panel is sealed in the opening slot when the spindle is in the initial position.

[0019] A car door is also provided, including the aforementioned concealed door handle and a door body. The base plate of the concealed door handle is installed on the door body, and one side of the base plate corresponds to the inside of the door body. When unlocking, the handle panel rotates toward the inside of the door body.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The hidden handle has a simple and ingenious structure. It can be equipped with an electric or fully mechanical structure as needed, so it can be adapted to high-end or economy vehicles. It is easy to operate. Pushing the handle panel inward can unlock the door and provide a latch structure at the same time, so that the door can be opened in one step.

[0022] 2. When this concealed door handle is used on economy vehicles, a torsion spring and a main shaft can be used to reset the handle panel. The entire door opening, unlocking and resetting process does not require an electric structure, so the structure is simple, practical and safe.

[0023] 3. When this concealed door handle is used on high-end vehicles, the main shaft can be driven by a motor to rotate, thereby achieving the effect of automatic unlocking and resetting. Even if the motor is damaged, the handle panel can be manually pushed to unlock the door, and the door unlocking function will not be affected by motor failure.

[0024] 4. Based on the structure of setting a torsion spring to achieve reset on the main shaft, a damper can be used to slow down the rotation of the main shaft, thereby making the handle panel rotate more smoothly and avoiding the user being injured or having their fingers pinched due to the excessive torque of the torsion spring causing the handle panel to quickly rebound and reset during the opening process.

[0025] 5. The concealed handle is very convenient to operate. The door can be unlocked and opened with just one hand by pressing and pulling. Users can press the handle panel with one hand and then put their hand into the opening slot (i.e., grab the handle structure) to unlock and pull the door open, which is very convenient.

Detailed Implementation

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figure 1-8As shown, a concealed exterior door handle includes: a base plate 100, a handle panel 200, and an unlocking mechanism. The base plate 100 has an opening slot 110, and one side of the base plate 100 is provided with a hinge seat 120 near the opening slot 110. The handle panel 200 is provided with a main shaft 210, which is circumferentially fixedly connected to the handle panel 200 and rotatably connected to the hinge seat 120. The unlocking mechanism includes an unlocking arm 300, an unlocking force block 400, and an unlocking traction cable 500. The unlocking arm 300 is rotatably sleeved on the main shaft 210, the unlocking force block 400 is circumferentially fixedly connected to the main shaft 210, and the unlocking traction cable 500 is connected to the unlocking arm 300. The shaft 210 can rotate circumferentially to an initial position or a linked position. When the main shaft 210 is in the initial position, the handle panel 200 is located in the opening slot 110. When the main shaft 210 rotates from the initial position to the linked position, the unlocking force block 400 moves towards the unlocking arm 300, and the handle panel 200 separates from the opening slot 110, thereby exposing the opening slot 110 to form a handle structure for opening the car door. When the main shaft 210 rotates to the linked position, the unlocking force block 400 abuts against the unlocking arm 300, and when the main shaft 210 continues to rotate past the linked position, the unlocking force block 400 drives the unlocking arm 300 to rotate, thereby pulling the unlocking traction cable 500.

[0037] In the actual structure, the base plate 100 has a plate-like structure, and the handle panel 200 has a main shaft 210 fixed on its side. The handle panel 200 can be hinged to the hinge seat 120 through the main shaft 210, so the handle panel 200 can rotate on the base plate 100. When the handle panel 200 rotates, the main shaft 210 rotates synchronously. The main shaft 210 actually rotates around its own axis, that is, the main shaft 210 can rotate circumferentially. When the main shaft 210 moves to a certain position, it can drive the unlocking mechanism to perform the unlocking action.

[0038] In the unlocking mechanism, the unlocking force block 400 and the unlocking arm 300 are axially adjacent to each other on the main shaft 210. The unlocking force block 400 can be regarded as a protrusion set on the surface of the main shaft 210 and extending in the axial direction. The unlocking force block 400 rotates synchronously with the main shaft 210, that is, when the main shaft 210 rotates, it can drive the unlocking force block 400 to rotate synchronously. The unlocking arm 300 consists of an annular component and an arm extending radially from the annular component. The unlocking arm 300 is rotatably connected to the main shaft 210. Therefore, when the main shaft 210 rotates within a certain angle range, the unlocking arm 300 does not rotate with the main shaft 210. Only when the unlocking force block 400 abuts against the radially protruding arm on the unlocking arm 300 and the main shaft 210 continues to rotate toward the end position can the unlocking arm 300 be driven to rotate, thereby pulling the unlocking traction cable 500.

[0039] Specifically, the main shaft 210 can rotate from the initial position to the end position (the initial position and the end position are the two ends of the stroke of the main shaft 210), the linkage position is between the initial position and the end position, and the stroke area of ​​the main shaft 210 between the initial position and the linkage position is the neutral area, and the stroke area of ​​the main shaft 210 between the linkage position and the end position is the unlocking area. When the main shaft 210 rotates in the neutral area, the unlocking arm 300 and the unlocking force block 400 are separated, and the torque of the main shaft 210 cannot be transmitted to the unlocking arm 300. When the main shaft 210 is in the unlocking area and rotates towards the end position, the unlocking force block 400 and the radially protruding arm on the unlocking arm 300 abut together. Therefore, the main shaft 210 can transmit torque to the unlocking arm 300 through the unlocking force block 400, thereby pulling the unlocking traction cable 500 and realizing the unlocking action.

[0040] In normal operation, the handle panel 200 covers the opening slot 110, thus concealing the opening slot 110 and hiding the handle structure. When the door is opened, the user pushes the handle panel cover inward, causing the main shaft 210 to rotate from the initial position to the end position (linkage position). At this time, the opening slot 110 is exposed, forming the handle structure. The user can reach into the opening slot 110 and hold the handle structure. When the main shaft 210 rotates in the neutral zone, it will not trigger the unlocking mechanism to perform the unlocking action. Only when the main shaft 210 rotates to the linkage position will the unlocking force block 400 and the unlocking arm 300 come into contact. As the main shaft 210 passes the linkage position and rotates towards the end position (i.e., the main shaft 210 enters the unlocking zone), the unlocking force block 400 pushes the unlocking arm 300 to rotate, thereby pulling the unlocking traction cable 500 to unlock the door.

[0041] It is important to note that the hidden handle in this embodiment is very convenient to operate. The door can be unlocked and opened with just one press and pull action. The user can press the handle panel 200 with one hand and then put his hand into the opening groove 110 (i.e., grab the handle structure) to unlock and pull the door open, which is very convenient.

[0042] The concealed handle has a simple and ingenious structure. It can be powered by an electric or fully mechanical mechanism as needed, making it suitable for both high-end and economy vehicles. It is also easy to operate. Pushing the handle panel 200 inwards unlocks the door and provides a latch, allowing for a one-step door opening.

[0043] It should also be noted that the structure of this concealed door handle is very ingenious. It can be set as an electric structure or a fully mechanical structure according to actual needs, and has strong applicability. For example, when used in economy vehicles, the torsion spring 130 can be used in conjunction with the main shaft 210 to reset the handle panel 200. The entire door opening, unlocking and resetting process does not require the use of an electric structure, so the structure is simple, practical and safe. When used in high-end vehicles, the main shaft 210 can be driven by a motor to rotate, thereby achieving the effect of automatic unlocking and resetting. Even if the motor is damaged, the handle panel 200 can be manually pushed to unlock, and the door opening and unlocking function will not be affected by motor failure.

[0044] In an embodiment where the concealed exterior door handle adopts a fully mechanical structure, the concealed exterior door handle further includes a torsion spring 130, which is sleeved on the main shaft 210. One end of the torsion spring 130 is connected to the base plate 100 and the other end is connected to the main shaft 210. The torsion spring 130 applies a torque to the main shaft 210 to rotate it toward the initial position.

[0045] The spindle 210 is held in its initial position by the torque generated by the torsion spring 130, thereby covering the opening slot 110 with the handle panel 200 and hiding the handle structure. After unlocking or when the handle panel 200 is pushed, the torsion spring 130 can push the spindle 210 to reset and return the spindle 210 to its initial position.

[0046] In an embodiment where the concealed exterior door handle adopts an electric structure, the concealed exterior door handle also includes a motor (not shown in the figure). The rotating shaft of the motor is connected to the main shaft 210. The main shaft 210 is controlled to rotate from the initial position to the linkage position and pass the linkage position by the forward rotation of the motor to achieve automatic unlocking, or the main shaft 210 is controlled to rotate to the initial position by the reverse rotation of the motor to achieve automatic reset.

[0047] The motor can control the rotation of the main shaft 210 by forward and reverse rotation, thereby realizing the automatic unlocking or automatic reset of the outer handle. Furthermore, although the main shaft 210 is automatically rotated by the motor, the unlocking principle used in this hidden door outer handle is very ingenious. Even if the motor fails, it can be unlocked by manual opening without affecting normal use. Therefore, it is very safe and functional.

[0048] like Figure 1-5 As shown, a damper 140 is also fixedly installed on one side of the base plate 100. The damper 140 is connected to the main shaft 210 to apply damping force to the rotation of the main shaft 210. Based on the structure of the main shaft 210 with a torsion spring 130 for reset, the damper 140 can also slow down the rotation of the main shaft 210, thereby making the handle panel 200 rotate more smoothly and avoiding the user being injured or having their fingers pinched due to the excessive torque of the torsion spring 130 during the opening process.

[0049] like Figure 1-3 , Figure 8 As shown, the travel area of ​​the main shaft 210 between the initial position and the linkage position is the neutral area, and the travel area of ​​the main shaft 210 after passing the linkage position is the unlocking area. When the main shaft 210 rotates in the neutral area, the unlocking force block 400 separates from the unlocking arm 300. When the main shaft 210 rotates in the unlocking area, the unlocking force block 400 and the unlocking arm 300 are in contact and move synchronously.

[0050] The neutral zone and the unlocking zone can actually be understood as the angular range of the main shaft 210's circumferential rotation. For example, if the angle of the main shaft 210 at the initial position is 0° and the angle at the end position is 180°, and it rotates 130° from the initial position to the linkage position, then the range of the neutral zone is 0°-130°, and the range of the unlocking zone is 130°-180°. When the main shaft 210 rotates within the range of 0°-130°, the unlocking force block 400 does not contact the unlocking arm 300. At this time, the main shaft 210 is equivalent to being in a neutral state. Within this angular range, the handle panel 200 separates from the opening slot 110 and gradually exposes the handle structure. When the main shaft 210 rotates within the range of 130°-180° towards the end position, the unlocking force block 400 contacts the arm structure of the unlocking arm 300 and can transmit the torque of the main shaft 210.

[0051] The base plate 100 is provided with a limiting block 150. When the main shaft 210 rotates from the linkage position to the initial position, the unlocking arm 300 is abutted by the limiting block 150 and separated from the unlocking force block 400. It should be noted that after unlocking is completed, the main shaft 210 returns to its original position under the action of the motor or the torsion spring 130, and the unlocking arm 300 returns to its original position under the action of the unlocking traction cable 500 until the unlocking arm 300 abuts against the limiting block 150. At this time, the main shaft 210 continues to rotate and return to its original position, and the unlocking force block 400 separates from the unlocking arm 300.

[0052] The base plate 100 is covered with a protective shell 160, and the protective shell 160 covers the handle panel 200. The main function of the protective shell is to prevent hands from being pinched and to prevent rainwater and debris from entering the door through the opening slot 110.

[0053] like Figure 1-4 , Figure 5 As shown, the base plate 100 is provided with a fixing block 170, and a limiting sleeve 180 is installed on the fixing block 170. The unlocking traction cable 500 is movably inserted into the limiting sleeve 180. The limiting sleeve 180 and the unlocking traction cable 500 form a structure similar to a bicycle brake cable. The limiting sleeve 180 can limit and hold the unlocking traction cable 500, providing support for the unlocking traction cable 500. The unlocking arm 300 can pull the unlocking traction cable 500 to move within the limiting sleeve 180.

[0054] like Figure 1-3 As shown, the shape and size of the handle panel 200 are adapted to the shape and size of the opening slot 110, and when the main shaft 210 is in the initial position, the handle panel 200 is sealed within the opening slot 110. Therefore, under normal circumstances, the handle panel 200 fits perfectly when the handle is closed, which makes the appearance of the concealed handle more aesthetically pleasing.

[0055] like Figure 1-8 As shown, a car door is also provided, including the aforementioned concealed door handle and a door body 600. The base plate 100 of the concealed door handle is installed on the door body 600, and one side of the base plate 100 corresponds to the inside of the door body 600. When unlocking, the handle panel 200 rotates toward the inside of the door body 600.

[0056] It should be noted that the base plate 100 has two sides. One side corresponds to the inside of the door, that is, the side of the base plate 100 mentioned above. Therefore, the handle panel 200 rotates towards the inside of the door body 600 when unlocking. The unlocking mechanism, main shaft 210, torsion spring 130 or motor are all located inside the door body 600. The other side of the base plate 100 is located on the outer surface of the door body 600.

[0057] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0058] Furthermore, in this invention, descriptions involving "first," "second," "a," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0059] In this invention, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction between two elements, unless otherwise explicitly limited.

[0060] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
