Abstract
Description
Technical Field
[0001] This utility model relates to a door handle, and more particularly to a concealed door handle device and door for use in automobiles. Background Technology
[0002] With the popularization and development of automotive electrification, the degree of electrification and automation in automobiles is also increasing. Door handles play a crucial role in protecting the driver and passengers, ensuring vehicle safety, and providing anti-theft functions. Furthermore, in pursuit of modern standards such as aesthetics and automation, cars with concealed door handles are now widely used in various vehicle models.
[0003] Cars with concealed door handles not only offer a clean and aesthetically pleasing design on the exterior of the doors, but also reduce wind resistance and noise during driving due to the absence of protruding handles. However, concealed door handles require the car's monitoring or control system (such as the ECU) to determine when to extend the handle to a hand-grip position (commonly known as the "welcome position" or "welcome state") and when to retract it into the door for concealment. Therefore, concealed door handles need to constantly send signals of their position status for the car's monitoring and control system to confirm and take appropriate control actions.
[0004] Existing concealed door handle technology primarily relies on sensors; when the handle is in a specific position, pressing the sensor allows the vehicle's system to confirm the handle's location. However, concealed door handles can be affected by external factors (such as accidental touches by the driver or passengers) during operation, leading to incorrect handle displacement, misjudgments, or even damage to the handle.
[0005] In view of this, in order to improve and solve the above-mentioned deficiencies, the creator has devoted himself to research and applied theoretical knowledge, and finally proposed a utility model with a reasonable design that effectively improves the above-mentioned deficiencies.

[0059] To further disclose the features and technical content of this utility model, please refer to the following detailed description and drawings of this utility model. However, the drawings are provided for reference and illustration only and are not intended to limit this utility model.
[0060] Please see Figures 1 to 4 The figures shown are a three-dimensional composite view and an exploded three-dimensional view from one perspective, and a three-dimensional composite view and an exploded three-dimensional view from another perspective. This utility model provides a concealed door handle device and a door thereof. The concealed door handle device (hereinafter referred to as door handle device A) is used to install on a door B to facilitate manual operation of the door B for opening or closing. The door handle device A includes a handle base 1, a handle 2, a driver 3, and a sensor switch group 4.
[0061] The grip seat 1 is for mounting on the aforementioned door B, and the grip seat 1 has a grip groove 10 formed by recessing from the outside of door B into the inside of door B. Figures 6 to 9 As shown in the embodiment of this utility model, the grip seat 1 can also be integrally formed with the car door B or become part of the car door B; that is, the car door B has a car door body B1, and the car door body B1 has an outer side surface B2, and the grip groove 10 is formed by recessing into the car door B from the outer side surface B2.
[0062] like Figure 2 and Figure 4 As shown, the grip 2 is housed in the grip groove 10 and is used for hand gripping to facilitate opening or closing the car door B. The grip 2 has a pivot 20 and an end 21 away from the pivot 20. The pivot 20 is pivotally mounted in the grip groove 10. The pivot 20 of the grip 2 can be pivotally mounted in the grip groove 10 by a pivot 200, so that the grip 2 can rotate around the pivot 20. In another preferred embodiment, the grip 2 can be pivotally mounted in the grip groove 10 by providing a protruding shaft (not shown) directly on the pivot 20. In other preferred embodiments, a protruding shaft (not shown) can be provided in the grip groove 10 towards the grip 2 and pivotally mounted on the pivot 20, so that the grip 2 can rotate around the pivot 20. When the grip 2 rotates around the pivot 20, the end 21 of the grip 2 can move outward from the grip groove 10, or in the opposite direction, the grip 2 can be retracted into the grip groove 10. Furthermore, the grip 2 is provided with an actuating part 22 near its pivot 20, and the actuating part 22 is located within the grip seat 1 or grip groove 10. In this embodiment, the actuating part 22 is integrally formed with the grip 2. In the embodiment of this utility model, the grip groove 10 is provided with a through hole 100 opposite to the actuating part 22, so that the actuating part 22 can pass through the through hole 100 and be located on the rear side of the grip seat 1 (i.e., as shown in the figure). Figure 1 and Figure 3 (As shown).
[0063] like Figure 2 and Figure 4 As shown, the actuator 3 is disposed on the grip base 1 and is used to drive the grip 2 to rotate around its pivot 20, thereby allowing the end 21 of the grip 2 to move outward from the grip groove 10 and unfold. In the embodiment of this utility model, the actuator 3 consists of a push rod 30 driven by a motor (not shown) and a slider 31. The slider 31 slides linearly on the grip base 1 by the push of the push rod 30. Specifically, the grip base 1 is provided with a groove 11, and the slider 31 can slide linearly in the groove 11. The slider 31 may be provided with a push part 310 facing the grip 2 to push the pivot 20 of the grip 2 to one side, thereby enabling the grip 2 to perform the aforementioned unfolding or hiding actions. In a feasible embodiment, the grip 2 may further be integrally provided with a pushing part 23 between the aforementioned actuating part 22 and pivot part 20; that is, the pushing part 23 is located on one side of the pivot part 20, and then the actuating part 22 protrudes from the pushing part 23. Moreover, the pushing part 23 has a pushing surface 230 that abuts against the pushing part 310. Therefore, when the pushing rod 30 pushes the slider 31, the slider 31 can drive the pushing part 310 to push against the pushing surface 230 of the grip 2, thereby allowing the grip 2 to rotate around its pivot part 20.
[0064] Please refer to the following: Figure 2 , Figure 4 and Figure 5The door handle device A may further include a return mechanism 5, which has a swing body 50, an elastic component 51 and a cable puller 52. The swing body 50 is pivotally mounted on the back side of the handle seat 1 or handle groove 10 and is connected to a fixed point by the elastic component 51. The fixed point may be the handle seat 1 or any fixed position such as on the door B. That is, one end of the elastic component 51 is connected to the swing body 50 and the other end of the elastic component 51 is connected to the fixed point. Furthermore, the swing body 50 is pushed and rotated by the aforementioned actuating part 22 or pushing part 23. In this embodiment, the pushing part 23 has a protrusion 231 on the side facing the swing body 50 to contact the swing body 50 and further push the swing body 50 to rotate, thereby pulling the elastic component 51 into a stretched state. In this embodiment, the elastic component 51 is a tension spring. In this stretched state, the elastic component 51 provides an elasticity (restoring force) to the swing body 50. In addition, the swing body 50 further pulls a door lock (not shown) by linking with the pull cable 52, thereby pulling the elastic component 51 and simultaneously stretching the pull cable 52, so that the door lock of the car door B can be unlocked by the pull cable 52, so that the car door B can be opened when the aforementioned handle 2 is pulled outward by hand.
[0065] Please refer to the following: Figures 5 to 8 As shown, the present invention mainly involves providing a sensing switch group 4 on the aforementioned grip base 1. The sensing switch group 4 can be disposed on the back side of the grip base 1 or grip groove 10, and is disposed opposite to the actuating part 22 of the aforementioned grip 2, for example, disposed above or below the actuating part 22. The sensing switch group 4 includes a first sensing switch 40, a second sensing switch 41, and a third sensing switch 42. In the embodiment of the present invention, the first, second, and third sensing switches 40, 41, and 42 can all be push switches (but can also be designed as other types or categories of sensors such as light-blocking sensors). By using the high and low positions of a first actuating surface 220 and a second actuating surface 221 formed on the actuating part 22, they can respectively interact with each sensing switch to achieve whether or not they are touched, thereby providing corresponding signals to provide feedback or report on the movement position of the grip 2 to the vehicle door control system. Furthermore, in the embodiments described in this utility model, the signal of the first sensing switch 40 is set to be in an off state (OFF) when pressed or sensed, while the signals of the second sensing switch 41 and the third sensing switch 42 are set to be in a communication state (ON) when pressed or sensed; that is, the normal state of the first sensing switch 40 is the opposite of that of the second sensing switch 41 and the third sensing switch 42.
[0066] As mentioned above, Figure 5 and Figure 6As shown, when the grip 2 is received in the grip groove 10 of the grip seat 1 or in the door B, the second actuating surface 221 of the actuating part 22 corresponds precisely to the first sensing switch 40. The second actuating surface 221 is formed by partially tilting downwards from the first actuating surface 220. Specifically, the first actuating surface 220 has a larger width D and a smaller width d facing the grip 2. The terms "larger" and "smaller" refer to the relative size relationship between the larger width D and the smaller width d, not defined as a maximum or minimum. The second actuating surface 221 lies between the smaller width d and the pivot 20 or the pushing part 23. Therefore, when the grip 2 is housed in the grip slot 10, the first sensing switch 40 is in an off state due to being pressed by the first actuating surface 220, while the second and third sensing switches 41 and 42 are not pressed or sensed because they are not in contact with the first actuating surface 220, and are therefore also in an off state.
[0067] like Figure 6 and Figure 7 As shown, when a user is outside door B and needs to open door B using handle 2, the user can press the front end of handle 2 (i.e., the end adjacent to pivot 20, or the opposite end of handle 2's end 21), and handle 2 will open. Figure 7 After a slight counterclockwise rotation, the first sensing switch 40 briefly disengages from the first actuating surface 220 and briefly enters the communication state (ON). When the car door control system receives this state change, it can drive the driver 3 to operate. The motor of the driver 3 causes the push rod 30 and a slider 31 to move linearly. The pushing part 310 of the slider 31 drives the pushing part 23, thereby causing the grip 2 to rotate. At this time, the end 21 of the grip 2 moves outward from the grip groove 10.
[0068] like Figure 5 and Figure 7As shown, when the aforementioned driver 3 pushes the end 21 of the grip 2 out of the grip groove 10 and moves it to a first position P1, the first position P1 is in a half-open state (or commonly known as the "welcoming state" or "welcoming position"). The first position P1 can be programmed to control the time required for the motor to drive the grip 2 to move to the first position P1, or to make the grip 2 stay in the first position P1 for a certain period of time, and wait for the period of time to pass without touching the grip, and then automatically return the grip to the grip groove 10. The aforementioned actuating part 22, due to displacement, causes the first actuating surface 220 to move away from the first sensing switch 40, and the first sensing switch 40, due to the downward tilt of the second actuating surface 221, is in an unpressed or unsensed communication state (ON). Therefore, the vehicle's door control system can be notified in advance to prepare. At the same time, when the first actuating surface 220, with its downwardly tilted leading surface 220a, contacts the second sensing switch 41, the leading surface 220a and the second actuating surface 221 are respectively located on both sides of the first actuating surface 220, so that the second switch 41 can change from an unpressed or unsensed state to a pressed or sensed communication state (ON) along the leading surface 220a. This gradually informs the vehicle's door control system that the handle 2 has reached the first position P1, and stops the drive 3, thereby keeping the handle 2 at the first position P1, waiting for the user to hold the handle 2 and open the door B.
[0069] like Figure 5 and Figure 8 As shown, when the user pulls the end 21 of the handle 2 from the first position P1 to a second position P2, the second position P2 is in the open state. The first actuating surface 220 of the actuating part 22 continues to contact the third sensing switch 42 with its leading surface 220a, while the second switch 41 is also kept on the first actuating surface 220 (that is, the surface area of the first actuating surface 220 can cover the setting distance between the second sensing switch and the third sensing switch). Therefore, both the second sensing switch 41 and the third sensing switch 42 are in a communication state (ON), that is, they inform the vehicle's door control system that the handle 2 has reached the second position P2 and unlocks the door to open the door B.
[0070] Furthermore, such as Figure 7 and Figure 9 As shown, when the grip 2 is in the first position P1 or rotated toward the first position P1, if the end 21 of the grip 2 is accidentally affected by an external force such as a human hand accidentally touching it, the second sensing switch 41 will be activated due to the grip 2 being accidentally touched (i.e., Figure 9The handle 2 is pushed slightly inward (as indicated by the arrow) so that it cannot be pressed or sensed by the first actuating surface 220 and retract to the leading surface 220a. Therefore, its signal changes from communication state (ON) to disconnection state (OFF) to immediately inform the car door control system that the actuating position of the handle 2 is affected and needs to be restarted, or the handle 2 is reversed and retracted to the first position P1 by the drive of the motor of the driver 3, so as to accurately grasp the position of the handle 2 and avoid damage to it.
[0071] Therefore, by means of the concealed door handle device of this utility model, which uses at least two of the first, second and third sensing switches 40, 41 and 42 mentioned above for feedback, the movement position of the handle 2 can be determined more accurately, and the accidental touch or accidental pressure can be detected in real time, so as to avoid damage to the handle 2.
[0072] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Therefore, all equivalent structural changes made based on the contents of the present utility model specification and drawings are also included in the scope of the present utility model.
