Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a concealed door handle device for automobiles and an automobile. Background Technology

[0002] With the rapid development of new energy vehicles, especially the rise of pure electric vehicles, hidden door handles are being widely used in cars. Hidden door handles seem to be becoming a standard feature of electric vehicles. Hidden door handles can reduce air resistance and make the overall appearance of the vehicle more integrated. At the same time, the pop-out and retraction of the door handles greatly enhances the sense of ceremony, technology and intelligence of the vehicle.

[0003] However, in certain situations, modern concealed door handles are prone to failing to pop out, preventing the door locks from opening. For example, in cold winters, especially with ice and snow, concealed door handles can freeze and fail to pop out, preventing the driver and passengers from entering the vehicle. Similarly, in extreme cases of collisions and damage, concealed door handles may fail to pop out during external rescue operations, hindering rescue efforts and posing a safety hazard to the driver and passengers. Summary of the Invention

[0004] The purpose of this application is to provide a car hidden door handle device and a car, so as to solve to a certain extent the technical problem that the hidden door handle in the prior art is prone to failing to pop out under certain special circumstances, resulting in the door lock being unable to be opened.

[0005] According to a first aspect of this application, a concealed handle device for automobiles is provided, including a handle assembly and a mounting portion, wherein the handle assembly includes a handle, a transmission body and a control valve portion;

[0011] Preferably, it also includes an identity verification unit, which is disposed on the handle and is communicatively connected to the control valve unit. The control valve unit can only control the vehicle lock to unlock after the identity verification unit issues an identity verification command.

[0012] The predetermined pivot includes a first pivot, and the end of the handle away from the hand grip groove is hinged to the transmission body via the first pivot.

[0013] Preferably, the micro-motion electronic control part includes a first micro switch, which is disposed on the end face of the transmission body facing the handle, so as to be able to sense the angle of rotation of the handle about the first rotating shaft;

[0017] When the handle assembly is in the hidden position, the outer surface of the handle is flush with the mounting panel;

[0018] When the handle assembly is in the extended position, at least a portion of the handle assembly can extend relative to the mounting panel.

[0019] Preferably, the predetermined rotating shaft further includes a second rotating shaft, the extension direction of which intersects the extension direction of the first rotating shaft;

[0020] The transmission body includes a support rod, the extension direction of which is perpendicular to the handle, one end of which is connected to the first end of the handle, and the other end of which is hinged to the second rotating shaft.

[0021] The micro-motion electronic control part includes a second micro switch, which is disposed at the second end of the handle to sense the angle of rotation of the handle about the second pivot axis;

[0022] The mechanical control part includes a second transmission component, which is throttlely connected to the second end of the handle;

[0023] The handle assembly further includes a second adsorption part, which is capable of adsorbing and releasing the second end of the handle to control whether the handle can rotate about the second pivot.

[0024] Preferably, the transmission body further includes a connecting rod and a guide rod, one end of the connecting rod is hinged to the second rotating shaft, the other end of the connecting rod is fixedly connected to the guide rod, and the second end of the handle is movably connected to the guide rod;

[0025] Both the second adsorption part and the second micro switch are disposed between the guide rod and the second end of the handle.

[0026] Preferably, the drive assembly includes a rotary drive component, a lead screw, a first hinge shaft, and a second hinge shaft, wherein the rotary drive component is connected to the lead screw via a transmission connection.

[0027] The lead screw is arranged parallel to the connecting rod, and the first hinge shaft and the second hinge shaft are cross-hinged.

[0028] One end of the first hinge shaft is connected to the lead screw drive, and the other end of the first hinge shaft is fixedly connected to the connecting rod.

[0029] One end of the second hinge shaft is fixedly connected to the lead screw, and the other end of the second hinge shaft is slidably connected to the connecting rod.

[0030] According to a second aspect of this application, an automobile is provided, including a control device and a plurality of automobile hidden handle devices as described in any of the above-described technical solutions, thus possessing all the beneficial technical effects of the automobile hidden handle device, which will not be repeated here.

[0031] Specifically, the control device is communicatively connected to multiple of the car's hidden door handles, so that the car can independently set the unlocking mode of each of the car's hidden door handles.

[0032] Preferably, the vehicle further includes a temperature detection device and a collision sensing device, both of which are communicatively connected to the vehicle's concealed door handle device via a control device.

[0033] The unlocking modes of the car's concealed door handle device include concealed mode, extended mode, and emergency mode;

[0034] When the car's hidden handle device is in the hidden mode, the handle assembly is positioned in the hidden position, the first suction part releases the handle, and the second suction part absorbs the handle;

[0035] When the car's concealed handle device is in the extended mode, the handle assembly is positioned in the extended position, the first suction part attracts the handle, and the second suction part releases the handle;

[0036] When the collision sensing device detects a collision signal, the car's hidden door handle device switches to the emergency mode;

[0037] When the car's concealed handle device is in emergency mode, the first and second suction parts simultaneously release the handle;

[0038] And / or, the drive component is configured to have adjustable output power;

[0039] When the car's concealed door handle receives an extension command, and the drive assembly does not push the handle assembly from the concealed position to the extended position:

[0040] If the ambient temperature detected by the temperature detection device is higher than the predetermined temperature, the control device will increase the output power of the drive component and drive the drive component to push out the handle component again.

[0041] If the ambient temperature detected by the temperature detection device is lower than the predetermined temperature, the control device drives the drive component to push out the handle component multiple times, and the output power of the drive component increases successively.

[0042] Compared with the prior art, the beneficial effects of this application are as follows:

[0043] The concealed door handle device provided in this application features a handle recess on a mounting panel. The handle extends from the mounting recess to the handle recess, and the portion of the handle recess is exposed by the handle. By hinged to a transmission body, rotating the handle relative to the transmission body to a second predetermined angle allows for unlocking of the vehicle lock via a mechanical control unit. Thus, while maintaining the concealed function of the door handle device, the lock can be unlocked by moving the handle through the handle recess. Even when the concealed door handle cannot be extended, the lock can still be unlocked by moving the handle through the handle recess. Even if the micro-motion electronic control unit fails under extreme conditions (e.g., power failure due to an accident or malfunction), the user can still unlock the lock using the mechanical control unit by moving the handle to the second predetermined angle through the handle recess. This effectively reduces the probability of the concealed door handle device failing to unlock, improving vehicle safety.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0058] The following reference Figures 1 to 5 This application describes a concealed door handle device and a car according to some embodiments.

[0059] See Figures 1 to 5 As shown, an embodiment of the first aspect of this application provides a concealed door handle device for automobiles, comprising a handle assembly and a mounting portion. The handle assembly includes a handle 21, a transmission body, and a control valve portion. The mounting portion includes a mounting panel 11, and is provided with a mounting groove 13 and a hand-holding groove 12, both recessed from the mounting panel 11 into the mounting portion. The mounting groove 13 and the hand-holding groove 12 are interconnected. The handle assembly is disposed inside the mounting groove 13, and the handle 21 extends from the mounting groove 13 to the hand-holding groove 12, with a portion of the hand-holding groove 12 being exposed by the handle 21. The handle 21 is hinged to the transmission body, and a user can actuate the handle 21 via the hand-holding groove 12 to rotate the handle 21 relative to the transmission body about a predetermined pivot. The control valve portion includes a micro-motion electronic control portion and a mechanical control portion. The handle assembly is communicatively connected to the vehicle lock via the micro-motion electronic control portion, and the handle assembly is drive-connected to the vehicle lock via the mechanical control portion. When the handle 21 rotates relative to the transmission body at a first predetermined angle, the micro-motion electronic control part can generate a control signal to unlock the vehicle lock; when the micro-motion electronic control part is in a malfunctioning state, the handle 21 rotates relative to the transmission body at a second predetermined angle, and the vehicle lock can be unlocked by the mechanical control part, wherein the second predetermined angle is greater than the first predetermined angle.

[0060] According to the aforementioned technical features, the car's concealed door handle device features a hand-operated groove 12 on the mounting panel 11. A handle 21 extends from the mounting groove 13 to the hand-operated groove 12, and a portion of the hand-operated groove 12 is exposed by the handle 21. By hinged to the transmission body, rotating the handle 21 relative to the transmission body to a second predetermined angle allows for unlocking of the car lock via a mechanical control unit. Thus, while maintaining the concealed function of the car's door handle device, the door lock can be unlocked by moving the handle 21 through the hand-operated groove 12. Even when the concealed door handle cannot be extended, the door lock can still be unlocked by moving the handle through the hand-operated groove 12. Even if the micro-motion electronic control unit fails under extreme conditions (e.g., power failure due to an accident or malfunction), the user can still unlock the car lock by moving the handle 21 to the second predetermined angle through the hand-operated groove 12 using the mechanical control unit. This effectively reduces the probability of the concealed door handle device failing to unlock, improving vehicle safety.

[0061] Preferably, such as Figures 1 to 3As shown, the aforementioned hidden door handle device may also include an identity verification unit 3, which is located on the handle 21 and is communicatively connected to the control valve unit. When the identity verification unit 3 issues an identity verification command, the control valve unit can control the unlocking of the car lock so as to identify whether the car key meets the unlocking requirements through the identity verification unit 3. It should be noted that the car key is not limited to the key body. The car key can be understood as a key in a broad sense, that is, it can refer to any means that can identify the owner's information, such as fingerprints, electronic keys, etc.

[0062] Optionally, the aforementioned identity verification unit 3 may be a door sensor switch, such as a PE switch.

[0063] In an embodiment, such as Figure 2 and Figure 3 As shown, the car's concealed handle assembly may further include a drive assembly 5, which is tractively connected to the handle assembly to drive the handle assembly to move between a concealed position and an extended position. When the handle assembly is in the concealed position, the outer surface of the handle 21 is flush with the mounting panel 11. When the handle assembly is in the extended position, at least a portion of the handle assembly can extend relative to the mounting panel 11, thereby realizing the concealing and extending actions of the handle of the car's concealed handle assembly.

[0064] Preferably, such as Figure 2 and Figure 3 As shown, the drive assembly 5 may include a first hinge pin 52, a second hinge pin 53, a rotary drive member 51, and a lead screw 54. The rotary drive member 51 is connected to the lead screw 54. The first hinge pin 52 and the second hinge pin 53 are cross-hinged. One end of the first hinge pin 52 is connected to the lead screw 54, and the other end is fixedly connected to the connecting rod 222. One end of the second hinge pin 53 is fixedly connected to the lead screw 54, and the other end is slidably connected to the connecting rod 222. Thus, when the rotary drive member 51 drives the lead screw 54 to rotate, it can drive the end of the first hinge pin 52 located on the lead screw 54 to move closer to / away from the end of the second hinge pin 53 located on the lead screw 54, thereby realizing the action of pushing out / retracting the handle assembly. Furthermore, the cross-hinged structure of the first hinge pin 52 and the second hinge pin 53 effectively improves the stability of the handle assembly's movement.

[0065] It should be noted that the above-mentioned drive component 5 is not limited to the structure of the first hinge shaft 52 and the second hinge shaft 53 that are cross-hinged. As long as the handle assembly can be pushed out and retracted relative to the mounting panel 11, the drive component 5 can also be other linear drive devices, such as cylinders, electric cylinders, linear motors, etc.

[0066] like Figures 2 to 5As shown, the aforementioned car hidden handle device can include two states, namely, a hidden state and an extended state. Correspondingly, the car hidden handle device can include a hidden mode unlock and an extended mode unlock. The structures for implementing the two unlock modes will be described separately below.

[0067] like Figure 4 and Figure 5 The diagram shows partial structural schematics of the car's hidden door handle device in the locked and unlocked positions in the hidden mode.

[0068] Preferably, such as Figure 4 and Figure 5 As shown, the aforementioned predetermined pivot may include a first pivot 61. The end of the handle 21 away from the hand-grip groove 12 is hinged to the transmission body via the first pivot 61. In this way, the distance between the first pivot 61 and the force application position of the handle 21 (i.e., the pulling torque of pulling the handle 21) is effectively increased, thereby saving pulling force.

[0069] like Figure 1 , Figure 4 and Figure 5 As shown, the first pivot 61 can be arranged parallel to the mounting panel 11 so that by flipping the handle 21 relative to the mounting panel 11, the car's hidden handle device can be put into the hidden mode to perform the unlocking action.

[0070] like Figure 1 , Figure 4 and Figure 5 An example is shown where the first pivot 61 is positioned at the upper edge of the handle 21, that is, where the handle 21 is positioned above the grip groove 12. However, this is not the only limitation; the position of the handle 21 is not limited to being positioned above the grip groove 12. As long as the handle can be turned via the grip groove 12, the grip groove 12 can also be positioned above, to the left, or to the right of the handle 21.

[0071] Optionally, such as Figure 4 and Figure 5 As shown, the handle 21 and the transmission body can be connected by a hinge, and the first pivot 61 can be the hinge pin of the hinge.

[0072] Preferably, as not shown in the figure, the micro-motion electronic control part described above may include a first micro switch. The first micro switch is disposed on the end face of the transmission body facing the handle 21 so as to sense the angle of rotation of the handle 21 about the first rotating shaft 61.

[0073] Preferably, such as Figure 4 and Figure 5As shown, the mechanical control part may include a first transmission member 421, which can be connected to the part of the handle 21 facing the transmission body so that when the handle 21 is flipped relative to the mounting panel 11 to a second predetermined angle, the vehicle lock can be unlocked by the first transmission member 421.

[0074] Optionally, both the first transmission component 421 and the second transmission component 422 described below can be mechanical cables. In this way, while ensuring that the pulling force of pulling the handle 21 can be transmitted to the vehicle lock, the tension of the mechanical cable can be used to act on the handle 21, so that the handle 21 can automatically return to its original position.

[0075] Preferably, such as Figure 4 and Figure 5 As shown, the handle assembly may further include a first adsorption part, which is disposed on the end face of the transmission body facing the handle 21. The first adsorption part can adsorb and release the handle 21 to control whether the handle 21 can rotate around the first rotating shaft 61. When the car hidden handle device is switched to the extended state, the handle 21 can be adsorbed and connected to the transmission body through the first adsorption part to facilitate the unlocking action in the extended state.

[0076] Optionally, such as Figure 4 and Figure 5 As shown, the first adsorption part may include a first battery iron and a first magnetic absorbing piece 712. The first electromagnet 711 and the first magnetic absorbing piece 712 are respectively disposed on the end face of the handle 21 and the transmission body facing the handle 21, so that the first adsorption part can adsorb and release the handle 21.

[0077] Preferably, as not shown in the figure, the first adsorption section may further include a first Hall sensor for sensing the adsorption state of the first adsorption section.

[0078] It should be noted that, with Figure 2 and Figure 3 Taking the structure of the transmission body shown in both examples as an example, the handle 21 is connected to two parts of the transmission body (i.e., one end of the support rod 221 and one end of the guide rod 223). In other words, the number of the above-mentioned structures for connecting the end of the transmission body with the handle 21 (i.e., hinge structure, first transmission member 421 and first micro switch) can be two sets, which are respectively set on the two parts of the transmission part facing the handle 21.

[0079] like Figure 3 A schematic diagram of the structure of a car's concealed door handle device in the locked position of its extended mode is shown.

[0080] Preferably, such as Figure 2 and Figure 3As shown, the second predetermined pivot may further include a second pivot 62, the extension direction of which may intersect with the extension direction of the first pivot 61, so that the action of pulling the handle 21 to drive the unlocking in the extended mode is different from the action of pulling the handle 21 to drive the unlocking in the hidden mode.

[0081] Preferably, such as Figure 2 and Figure 3 As shown, the extension direction of the second rotating shaft 62 is perpendicular to the extension direction of the first rotating shaft 61, so as to facilitate the pulling operation of the handle 21 and avoid confusion between the two modes of operation.

[0082] Preferably, such as Figure 2 and Figure 3 As shown, the transmission body may include a support rod 221, the extension direction of the support rod 221 is perpendicular to the handle 21, one end of the support rod 221 is connected to the first end of the handle 21, and the other end of the support rod 221 is hinged to the second rotating shaft 62.

[0083] Preferably, such as Figure 2 and Figure 3 As shown, the micro-motion electronic control part may also include a second micro switch 412. The second micro switch 412 is disposed at the second end of the handle 21 so as to sense the angle of rotation of the handle 21 about the second rotating shaft 62.

[0084] Preferably, such as Figure 2 and Figure 3 As shown, the aforementioned mechanical control part may include a second transmission component 422, which is connected to the second end of the handle 21 via a transmission connection.

[0085] Similarly, not shown in the figure, the handle assembly may also include a second adsorption part, which can adsorb and release the second end of the handle 21 to control whether the handle 21 can rotate around the second pivot 62. Its beneficial effects and specific structure are similar to the first adsorption part, and will not be described again.

[0086] Correspondingly, the second adsorption part may also include a second electromagnet, a second adsorption plate, and a second Hall sensor. Specifically, the second Hall sensor can detect the attraction state of the second magnetic plate and the second electromagnet. For example, during the process of switching the handle assembly from the extended position to the concealed position, the control device controls the second electromagnet to be energized to attract the second adsorption plate, and the second Hall sensor senses the attraction state of the second magnetic plate and the second electromagnet. If the second Hall sensor senses that the second end of the handle 21 is normally attracted to the guide rod 223, it normally controls the drive assembly 5 to retract the handle 21 assembly into the mounting groove 13. If the second Hall sensor does not sense that the second end of the handle 21 is attracted to the guide rod 223, it will send a reminder message to the control device to remind the user that there is a jam at the handle 21.

[0087] Preferably, such as Figure 2 and Figure 3 As shown, the transmission body may further include a connecting rod 222 and a guide rod 223. One end of the connecting rod 222 is hinged to the second rotating shaft 62, and the other end of the connecting rod 222 is fixedly connected to the guide rod 223. The connecting rod 222 may be arranged parallel to and opposite to the lead screw 54. The first hinge shaft 52 and the second hinge shaft 53 may be arranged on the connecting rod 222. The second end of the handle 21 is movably connected to the guide rod 223. Thus, when the handle 21 is pulled to rotate around the second rotating shaft 62, both the support rod 221 and the handle 21 rotate around the second rotating shaft 62. The second end of the handle 21 is movably connected to the guide rod 223, so that the guide rod 223 and the connecting rod 222 remain fixed, so that the connecting rod 222 always remains parallel to the lead screw, avoiding interference between the drive assembly 5 and the rotation of the handle 21.

[0088] Preferably, not shown in the figure, the second end of the handle 21 may be provided with a guide sleeve, which can be sleeved on the outside of the guide rod 223, and the guide rod 223 is connected to the handle 21 via the guide sleeve. The guide sleeve and the guide rod 223 are in clearance fit so that the handle 21 and the guide rod 223 are movably connected.

[0089] Correspondingly, the second adsorption part and the second micro switch 412 can both be disposed between the guide rod 223 and the guide sleeve. The second transmission member 422 can be connected to the guide sleeve for transmission.

[0090] It should be noted that the structure (i.e., hinge structure, first transmission member 421, and first micro switch) used for connecting the end of the transmission body to the handle 21 can be provided on the end face of the guide sleeve facing the handle 21. In other words, the guide sleeve is connected to the handle 21 via the structure used for connecting the end of the transmission body to the handle 21.

[0091] The second aspect of this application also provides an automobile that includes the automobile hidden handle device of any of the above embodiments, and thus has all the beneficial technical effects of the automobile hidden handle device, which will not be repeated here.

[0092] Specifically, the aforementioned vehicle may include a control device and multiple doors, and each door may be equipped with at least one of the aforementioned hidden handle devices. In other words, the aforementioned vehicle may include multiple of the aforementioned hidden handle devices.

[0093] Preferably, the control device is communicatively connected to multiple hidden door handle devices, so that the vehicle can independently set the unlocking mode of each hidden door handle device.

[0094] Alternatively, the aforementioned control device may be an on-board computer.

[0095] Preferably, the unlocking mode of the above-mentioned hidden handle device can include a hidden mode. When the hidden handle device is in the hidden mode, the handle assembly is set in the hidden position. At this time, the first suction part releases the handle 21, and the second suction part suctions the handle 21. Thus, the handle 21 can rotate about the first pivot 61.

[0096] Preferably, the unlocking mode of the above-mentioned hidden handle device can include an extension mode. When the hidden handle device is in the extension mode, the handle assembly is set in the extension position. At this time, the first suction part attracts the handle 21, and the second suction part releases the handle 21. Thus, the handle 21 can rotate about the second pivot 62.

[0097] Optionally, users can set the unlocking mode for each car's hidden door handle via the central control screen.

[0098] Optionally, users can set the unlocking mode for each car's hidden door handle by waking up the control device with their voice.

[0099] Optionally, users can set the unlocking mode for each car's hidden door handle by logging into the app via their mobile device.

[0100] Preferably, the vehicle may further include a collision sensing device, which is communicatively connected to the vehicle's hidden door handle device via a control device to collect information on whether a collision has occurred.

[0101] Optionally, the collision sensing device may include multiple strain gauges. It should be noted that collecting information on whether a car has collided through strain gauges is existing technology in this field and will not be described in detail here.

[0102] Preferably, the unlocking mode of the aforementioned hidden door handle device may also include an emergency mode. When the collision sensing device detects a collision signal, the hidden door handle device switches to this emergency mode. When the hidden door handle device is in emergency mode, the first and second suction parts simultaneously release the handle 21. This allows the handle 21 to rotate around both the first pivot 61 and the second pivot 62. In other words, regardless of how the handle 21 is rotated, unlocking can be achieved as long as the rotation angle in one direction exceeds the second predetermined angle. In extreme collision situations, this effectively increases the probability of the door lock being unlocked, thereby improving vehicle safety.

[0103] Preferably, the drive assembly 5 is configured to have adjustable output power. Taking the drive assembly 5 as an example, which consists of the rotary drive member 51 and the first hinge shaft 52 and the second hinge shaft 53 that are cross-hinged, the output power of the drive assembly 5 can be changed by changing the current of the rotary drive member 51.

[0104] Preferably, the vehicle may further include a temperature detection device, which is communicatively connected to the vehicle's concealed door handle device via a control device to collect the vehicle's temperature information.

[0105] Preferably, after the car's concealed handlebar device receives an extension command, and the drive assembly 5 has not yet pushed the handlebar assembly from the concealed position to the extended position: if the ambient temperature detected by the temperature detection device is higher than a predetermined temperature, the control device will increase the output power of the drive assembly 5, driving the drive assembly 5 to push out the handlebar assembly again; if the ambient temperature detected by the temperature detection device is lower than the predetermined temperature, the control device will drive the drive assembly 5 to push out the handlebar assembly multiple times, with the output power of the drive assembly 5 increasing sequentially. Optionally, the predetermined temperature can be 0℃ to 4℃. Thus, when the temperature is higher than the predetermined temperature (i.e., non-icebreaking mode), if the handlebar assembly cannot be pushed out, it may be due to obstruction. Only one additional push-out attempt is made, effectively reducing the risk of excessive push-out force and damage to the handlebar assembly from obstruction. When the temperature is lower than the predetermined temperature (i.e., icebreaking mode), the probability of the handlebar assembly failing to pop out due to icing is higher in this state. Multiple push-out attempts improve the success rate of ice breaking.
