Description

Technical Field

[0001] The present application relates to the technical field of vehicle parts, and in particular to a hidden door handle and a control method thereof, a vehicle door, and a vehicle. Background Art

[0002] As cars become more electrified and intelligent, more and more vehicles are using hidden door handles. These can enhance a vehicle's aesthetics and reduce wind resistance. However, in winter, especially in snowy areas, hidden door handles can easily freeze to the door. This can prevent the handles from popping out properly when the vehicle is unlocked, preventing the door from opening and hindering user experience.

[0003] In the prior art, de-icing concealed door handles is primarily achieved through heating or vibration alone. However, heating alone takes a long time, and while periodic heating can reduce ice buildup on concealed door handles, it requires cyclic heating, which consumes a lot of energy.

[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0064] In the first aspect, the embodiment of the present application provides a hidden door handle, see Figure 1 , comprising a door handle assembly 1, an ice-breaking assembly 2, and a drive assembly 3. The door handle assembly 1 is disposed within a receiving cavity 41 of a vehicle door body 4 and is loosely fitted with the receiving cavity 41. The door handle assembly 1 is adapted to reciprocate along a first direction Z so that the door handle assembly 1 pops out from the opening of the receiving cavity 41 or is at least partially embedded within the receiving cavity 41. It is understood that when the vehicle door needs to be opened, the door handle assembly 1 pops out from the opening of the receiving cavity 41, and when the vehicle door does not need to be opened, the door handle assembly 1 can be embedded within the receiving cavity 41.

[0065] The ice-breaking assembly 2 is disposed within the accommodating cavity 41 and is adapted to reciprocate along a first direction Z so that the ice-breaking assembly 2 pops out of the opening of the accommodating cavity 41 or is at least partially embedded within the accommodating cavity 41. It is understood that when the ice-breaking assembly 2 pops out of the opening of the accommodating cavity 41, it can pop out of the opening of the accommodating cavity 41 along the first direction Z. When the door handle assembly 1 is frozen, a layer of ice forms on the vehicle door body 4, making it difficult to open the door handle assembly 1. When the ice-breaking assembly 2 pops out, it can quickly break the ice layer on the vehicle door body 4, separating the door handle assembly 1 from the accommodating cavity 41 and allowing the door handle assembly 1 to pop out smoothly.

[0066] The driving assembly 3 is configured to drive the door handle assembly 1 and / or the ice-breaking assembly 2 to reciprocate along the first direction Z. The driving assembly 3 can provide a driving force for the door handle assembly 1 and / or the ice-breaking assembly 2, so that the door handle assembly 1 and / or the ice-breaking assembly 2 can reciprocate along the first direction Z.

[0067] The hidden door handle provided in the embodiment of the present application can quickly clear the ice layer on the vehicle door body 4 through the ice-breaking component 2, thereby improving the ice-breaking efficiency, reducing energy consumption, and reducing the vibration of the hidden door handle during the ice-breaking process, reducing the wear between the various components in the hidden door handle, and extending the service life.

[0068] In some embodiments, at least one protruding structure 211 is provided at one end of the ice-breaking assembly 2 close to the outlet of the accommodating cavity 41 .

[0069] According to the formula p = F / S, pressure is the ratio of the pressure applied to an object to the area affected by the force. By providing at least one protruding structure 211 at one end of the ice-breaking assembly 2 near the exit of the accommodating chamber 41, when the ice-breaking assembly 2 is breaking ice, the protruding structure 211 first pops out toward the opening of the accommodating chamber 41, reducing the contact area with the ice layer and thereby improving the ice-breaking effect.

[0070] In some embodiments, the width of the protrusion 211 gradually decreases toward the opening of the accommodating cavity. That is, the protrusion 211 is a sharp structure. By setting the protrusion 211 as a sharp structure, the ice-breaking effect of the ice-breaking assembly 2 can be further improved.

[0071] For example, see Figure 1 Six protrusions 211 are provided on the circumference of one end of the ice-breaking assembly 2 close to the outlet of the accommodating chamber 41. The protrusions 211 are triangular in shape, which further improves the ice-breaking effect.

[0072] It is understandable that the number and shape of the protruding structures 211 can be reasonably set according to actual needs. The above is only an exemplary description and is not intended to limit the scope of protection of this application.

[0073] In some embodiments, the driving assembly 3 is used to drive the ice-breaking assembly 2 to move along the first direction Z when the door handle assembly 1 is blocked from popping out of the accommodating cavity 41 along the first direction Z, so that the ice-breaking assembly 2 pops out of the opening of the accommodating cavity 41 along the first direction Z.

[0074] That is to say, when the door handle assembly 1 cannot normally pop out of the opening of the accommodating cavity 41, the driving assembly 3 drives the ice-breaking assembly 2 to move along the first direction Z to achieve ice breaking, so that the door handle assembly 1 can be smoothly popped out.

[0075] In some embodiments, the ice-breaking assembly 2 is configured to remain in the accommodating cavity 41 when the driving assembly 3 is capable of driving the door handle assembly 1 to pop out of the opening of the accommodating cavity 41 along the first direction Z.

[0076] That is to say, when the door handle assembly 1 can normally pop out of the opening of the accommodating cavity 41, the ice-breaking assembly 2 remains in the accommodating cavity 41, preventing the ice-breaking assembly 2 from popping out together with the door handle assembly 1 and affecting the user's opening of the car door.

[0077] In practical applications, this objective can be achieved in a variety of ways. For example, a sensor can be used to detect whether ice is present on the concealed door handle. If ice is not present, the drive assembly 3 is controlled to directly eject the door handle assembly 1. If ice is present, the drive assembly 3 is controlled to eject the ice-breaking assembly 2. Alternatively, the drive device can be first connected to the door handle assembly 1 to eject the door handle assembly 1. When the door handle assembly 1 ejects normally, the ice-breaking assembly 2 remains within the accommodating chamber 41. If the door handle assembly fails to eject normally, the drive assembly 3 is controlled to eject the ice-breaking assembly 2.

[0078] In some embodiments, see Figure 1 and Figure 2 The drive assembly 3 is arranged in the accommodating cavity 41. The drive assembly 3 includes a drive structure 31 and a transmission gear structure 32. The drive structure 31 and the transmission gear structure 32 are drivingly connected. The ice-breaking assembly 2 includes an ice-breaking structure 21, and a rack 22 connected to the ice-breaking structure 21, and the ice-breaking assembly 2 is connected to the vehicle door body 4 through a first elastic member 5. Wherein, the rack 22 and the first elastic member 5 both extend along the first direction Z. The transmission gear structure 32 is arranged on the door handle assembly 1, and the transmission gear structure 32 and the rack 22 are suitable for engaging with each other. Wherein, the transmission gear structure 32 has a missing tooth structure 3221. When the missing tooth structure 3221 corresponds to the rack 22, the transmission gear structure 32 and the rack 22 are disengaged.

[0079] The driving assembly 3 provided by the embodiment of the present application can control the door handle assembly 1 and the ice breaking assembly 2 to pop out in different situations.

[0080] Specifically, when ice is not formed, the drive structure 31 in the drive assembly 3 drives the transmission gear structure 32 to rotate, and the transmission gear structure 32 engages with the rack 22 in the ice-breaking assembly 2. Because the ice-breaking assembly 2 is connected to the vehicle door body 4 via the first elastic member 5, and the transmission gear structure 32 is provided on the door handle assembly 1, the elastic force of the first elastic member 5 keeps the ice-breaking assembly 2 stationary, while the transmission gear structure 32 drives the door handle assembly 1 in the first direction Z, thereby causing the door handle assembly 1 to pop out of the accommodating cavity 41. To retract the door handle assembly 1 from the accommodating cavity 41, the drive structure 31 simply drives the transmission gear structure 32 to rotate in the opposite direction.

[0081] In the event of ice formation, the drive mechanism 31 in the drive assembly 3 drives the transmission gear mechanism 32 to rotate, which then meshes with the rack 22 in the ice-breaking assembly 2. Because the door handle body and the accommodating cavity 41 are confined by ice, the transmission gear mechanism 32 is unable to force the door handle assembly 1 to eject properly. Furthermore, this resistance is greater than the elastic force of the first elastic member 5, causing the rack 22, coupled to the transmission gear mechanism 32, to move the ice-breaking mechanism 21 and the first elastic member 5, causing the first elastic member 5 to stretch or compress. When the transmission gear mechanism 32 rotates to the missing tooth structure 3221, the transmission gear mechanism 32 loses its meshing relationship with the rack 22. Under the elastic force of the first elastic member 5, the ice-breaking mechanism 21 moves in the first direction Z, impacting the gap between the door handle assembly 1 and the accommodating cavity 41 and achieving the ice-breaking effect. After ice-breaking is complete, the restoring force of the first elastic member 5 resets the ice-breaking assembly 2 and re-enters the accommodating cavity 41. It is understood that the ice-breaking effect can be improved by repeating this process multiple times until the door handle assembly 1 ejects properly.

[0082] In some embodiments, see Figure 1 The ice-breaking structure 21 is sleeved on the periphery of the door handle assembly 1, and the ice-breaking structure 21 is arranged in the gap between the door handle assembly and the accommodating cavity.

[0083] When ice forms, ice usually forms in the gap between the door handle assembly 1 and the accommodating cavity 41, causing the door handle assembly 1 to adhere to the accommodating cavity 41, thereby preventing the door handle assembly 1 from popping up. In the embodiment of the present application, an ice-breaking structure 21 is sleeved around the periphery of the door handle assembly 1, and the ice-breaking structure 21 is disposed in the gap between the door handle assembly 1 and the accommodating cavity 41. When the ice-breaking structure 21 pops out of the opening of the accommodating cavity 41 along the first direction Z, it can break the ice layer between the door handle assembly 1 and the accommodating cavity 41, separating the door handle assembly 1 from the accommodating cavity 41, thereby achieving an ice-breaking effect.

[0084] In some embodiments, see Figure 1 and Figure 6 The first elastic member 5 includes a first end and a second end arranged opposite to each other along the first direction Z. The first end of the first elastic member 5 is connected to the door body 4 near the opening of the accommodating cavity 41, and the second end of the first elastic member 5 is connected to an end of the rack 22 away from the opening of the accommodating cavity 41.

[0085] The first end of the first elastic member 5 is connected to the door body 4 near the opening of the accommodating cavity 41, thereby securing the first end. The second end of the first elastic member 5 is connected to the end of the rack 22 away from the opening of the accommodating cavity 41, thereby connecting the first elastic member 5 to the ice-breaking assembly 2. The first elastic member 5 connects the ice-breaking assembly 2 to the door body 4, limiting the position of the ice-breaking assembly 2.

[0086] It can be understood that when the first elastic member 5 is not subjected to external force, the position of the ice-breaking assembly 2 is relatively stable and maintained in the accommodating cavity 41. In the case of ice, if the door handle assembly 1 cannot pop out, when the drive assembly 3 is working, the transmission gear structure 32 cannot drive the door handle assembly 1 to pop out. On the basis of the meshing action of the transmission gear structure 32 and the rack 22, the first elastic member 5 is stretched and force is accumulated until the toothless structure 3221 of the transmission gear structure 32 corresponds to the rack 22. The meshing relationship between the transmission gear structure 32 and the rack 22 is destroyed. On the basis of the force accumulated by the first elastic member 5, the first elastic member 5 drives the rack 22 and the ice-breaking structure 21 connected to the rack 22 to move toward the opening of the accommodating cavity 41, causing an impact on the gap between the door handle assembly 1 and the accommodating cavity 41, thereby achieving the effect of breaking ice.

[0087] For example, see Figure 1 and Figure 6 The first elastic component can be a spring, a first end of the spring is connected to the door body through a first pull ring provided on the door body, and a second end of the spring is connected to the rack 22 through a second pull ring provided on the rack 22.

[0088] In some embodiments, the driving structure 31 includes a driving motor 311 and a driving worm 312 . The driving motor 311 is drivingly connected to the driving worm 312 , and the driving worm 312 is drivingly connected to the transmission gear structure 32 .

[0089] That is to say, the drive assembly 3 is driven and connected to the transmission gear structure 32 through the drive worm 312. The drive worm 312 can drive the transmission gear structure 32 to rotate, but the transmission gear structure 32 cannot drive the drive worm 312 to rotate. This is mainly because the protrusion angle on the drive worm 312 is shallow. When the transmission gear structure 32 tries to drive the drive worm 312 to rotate, the friction between the drive worm 312 and the transmission gear structure 32 will keep the drive worm 312 stationary. Through the cooperation between the drive worm 312 and the transmission gear structure 32, one-way transmission can be achieved, reducing the phenomenon of the drive motor 311 being blocked or overcurrent caused by the door handle assembly 1 or the ice breaking assembly 2 when subjected to external force, and reducing the risk of damage to the drive motor 311.

[0090] In some embodiments, see Figure 1-Figure 3The transmission gear structure 32 includes a first transmission gear 321, a second transmission gear 322 and a gear shaft 323. The first transmission gear 321 and the second transmission gear 322 are connected by the gear shaft 323, and the second transmission gear 322 has a toothless structure 3221. The driving worm 312 is drivingly connected to the first transmission gear 321, and the second transmission gear 322 is suitable for meshing with the rack 22. When the driving worm 312 rotates, it drives the first transmission gear 321 to rotate, and the first transmission gear 321 drives the second transmission gear 322 to rotate through the gear shaft 323, and the second transmission gear 322 meshes with the rack 22, so that the door handle assembly 1 moves along the first direction Z, or the ice breaking assembly 2 moves along the first direction Z.

[0091] That is, the driving motor 311 drives the driving worm 312 to rotate, and the driving worm 312 drives the first transmission gear 321 to rotate. Since the first transmission gear 321 and the second transmission gear 322 are connected by the gear shaft 323, when the first transmission gear 321 rotates, it drives the second transmission gear 322 to rotate. The second transmission gear 322 has a missing tooth structure 3221, see Figure 4 When the toothless structure 3221 corresponds to the rack 22, there is no meshing relationship between the second transmission gear 322 and the rack 22. When the second transmission gear 322 rotates to a position outside the toothless structure 3221, the second transmission gear 322 and the rack 22 mesh with each other.

[0092] Specifically, see Figure 1-Figure 4 The first transmission gear 321, the second transmission gear 322 and the gear shaft 323 are connected to the door handle assembly 1 through the gear bracket 324. When the transmission gear structure 32 moves as a whole, it can drive the door handle assembly 1 to move.

[0093] Through the configuration of this embodiment, the stability of the driving assembly 3 can be improved, and the energy storage and ejection of the ice-breaking assembly 2 can be achieved by utilizing the second transmission gear 322 with the tooth-missing structure 3221 .

[0094] In some embodiments, the driving motor 311 is an eccentric reduction motor, which is drivingly connected to the driving worm 312 .

[0095] The eccentric reduction motor has a strong transmission capacity and a large output torque, which can improve the driving effect. In addition, the space in the accommodating cavity 41 is relatively small. By using an eccentric reduction motor as the drive motor 311, it is possible to provide sufficient driving force while improving the convenience of the layout by rationally arranging the eccentric direction and position.

[0096] In some embodiments, the driving assembly 3 includes a first driving assembly and a second driving assembly. The first driving assembly and the second driving assembly are respectively arranged at opposite ends in the second direction X. The first direction Z and the second direction X are perpendicular to each other.

[0097] The door handle assembly 1 is usually long and narrow. By respectively arranging a first drive assembly and a second drive assembly at opposite ends of the door handle assembly 1 (i.e., opposite ends in the second direction X), the stability of the pop-up process can be improved and problems such as wear caused by offset can be reduced.

[0098] It is understandable that the structures of the first drive assembly and the second drive assembly are substantially the same, and will not be described in detail here.

[0099] In some embodiments, see Figure 5 The door handle assembly 1 is provided with a limiting portion 132, which is used to limit the distance that the door handle assembly 1 pops out of the accommodating cavity 41. The limiting portion 132 can prevent the door handle assembly 1 from escaping from the accommodating cavity 41, thereby improving the structural stability of the hidden door handle.

[0100] In some embodiments, see Figure 1 and Figure 5 The first sliding portion 7 is disposed in the accommodating cavity 41 and is connected to the vehicle door body 4. The door handle assembly 1 is provided with a second sliding portion 131. The first sliding portion 7 and the second sliding portion 131 are slidably connected to guide the movement of the door handle assembly 1 along the first direction.

[0101] See also Figure 1 and Figure 5 The first sliding portion 7 and the second sliding portion 131 can cooperate with each other, so that the door handle assembly 1 can move along the first direction Z, reducing the risk of deviation of the door handle assembly 1 during the pop-up and retraction process.

[0102] The first sliding portion 7 and the second sliding portion 131 can be matched in various ways. For example, the first sliding portion 7 can be provided with a slide groove, and the second sliding portion 131 can be provided with a corresponding slide rail. Alternatively, the first sliding portion 7 can be provided with a slide rail, and the second sliding portion 131 can be provided with a corresponding slide groove.

[0103] In some embodiments, see Figure 1A second elastic member 6 is provided between one end of the door handle assembly 1 in the second direction X and one end of the accommodating cavity 41 away from the opening of the accommodating cavity 41. In other words, one end of the door handle assembly 1 is elastically connected to the bottom of the accommodating cavity 41. When the hidden door handle malfunctions, one end of the door handle assembly 1 can be manually pressed to move it toward the bottom of the accommodating cavity 41, causing the other end to tilt upward and protrude out of the opening of the accommodating cavity 41. The user can then manually pull out the door handle assembly 1 to open the vehicle door.

[0104] For example, see Figure 1 The second elastic member 6 is a spring. When one end of the door handle assembly 1 corresponding to the second elastic member 6 is pressed, the second elastic member 6 is compressed, and the other end will be raised online, making it convenient to manually pull the door handle assembly.

[0105] In some embodiments, see Figure 1 and Figure 5 The door handle assembly 1 includes a heat-conducting panel 11, a heating element 12 and a door handle body 13 stacked along a first direction Z.

[0106] The heating element 12 can perform a heating function. When ice is present, the heating element 12 generates heat, which is transferred to the surface of the door handle assembly 1 through the heat-conducting panel 11, causing the ice to melt. The interaction between the heating element 12 and the ice-breaking assembly 2 can further enhance the ice-breaking effect and efficiency.

[0107] In some embodiments, see Figure 1 The hidden door handle also includes a position detection sensor 8, which is arranged in the accommodating cavity 41 and electrically connected to the heating element 12. The position detection sensor 8 is configured to detect the distance between the door handle assembly 1 and the position detection sensor 8 in the first direction Z.

[0108] The position detection sensor 8 can determine whether the door handle assembly 1 is ejected normally by detecting the distance between the door handle assembly 1 and itself. The position detection sensor 8 is electrically connected to the heating element 12. When it is determined that the door handle assembly 1 is not ejected normally, the heating element 12 starts heating.

[0109] According to the second aspect of the present application, a method for controlling a hidden door handle is also provided. Figure 7 ,include:

[0110] Step 100: According to the door unlocking instruction, the door handle assembly 1 is controlled to pop out of the opening on the door body 4;

[0111] Step 200: Determine the state of the door handle assembly 1. If the door handle assembly 1 is not ejected, start the ice breaking program.

[0112] The ice-breaking program includes controlling the driving component 3 to drive the ice-breaking component 2 to pop out of the opening on the vehicle door body 4 .

[0113] In the control method for a concealed door handle provided in an embodiment of the present application, upon receiving a door unlock command, the door handle assembly 1 is first controlled to pop out of an opening in the door body 4. The state of the door handle assembly 1 is then determined. If it has not popped out, an ice-breaking procedure is initiated. If it has popped out normally, the process ends. The ice-breaking procedure includes controlling the drive assembly 3 to drive the ice-breaking assembly 2 to pop out of the opening in the door body 4, thereby breaking ice.

[0114] In some embodiments, the ice breaking program further includes controlling the heating element 12 to heat the door handle assembly 1. That is, when ice is formed, the heating element 12 heats the door handle assembly 1 to accelerate the melting of the ice, and the ice breaking assembly 2 ejects and impacts the ice to improve the ice breaking effect.

[0115] In some embodiments, after determining the state of the door handle, the method further includes:

[0116] Determine whether the ambient temperature and humidity meet the preset conditions;

[0117] If the ambient temperature and humidity meet the preset conditions and the door handle assembly 1 does not pop out of the opening on the vehicle door body 4, the ice breaking program is started.

[0118] By judging the ambient temperature and humidity conditions before starting the ice-breaking program, it is possible to further confirm whether there is icing and improve the accuracy of the judgment.

[0119] For example, the preset conditions may be that the ambient temperature is ≤ 0° C. and the ambient humidity is ≥ 80%. When the above preset conditions are met, icing is likely to occur.

[0120] In some embodiments, after determining whether the ambient temperature meets the preset conditions, the method further includes:

[0121] If the ambient temperature and humidity do not meet the preset conditions, a fault alarm will be issued.

[0122] In actual use, other situations may cause the door handle assembly 1 to not eject properly. For example, a mechanical or control failure of the concealed door handle, or the presence of foreign matter in the gap between the door handle assembly 1 and the accommodating cavity 41, may occur. The ice-breaking program cannot resolve these issues. Therefore, if the ambient temperature and humidity do not meet the preset conditions, a fault alarm is issued to remind the user to take appropriate measures.

[0123] In some embodiments, after starting the icebreaking procedure, the method further includes:

[0124] Re-controlling the door handle assembly 1 to pop out of the opening on the vehicle door body 4 and determining the state of the door handle assembly 1;

[0125] If the door handle assembly 1 pops out of the opening on the vehicle door body 4, the control program ends.

[0126] That is, the ice-breaking program can be started multiple times to improve the ice-breaking effect.

[0127] In some embodiments, after re-controlling the door handle assembly 1 to pop out and determining the state of the door handle assembly 1, the method further includes:

[0128] If the door handle assembly 1 does not pop out of the opening on the vehicle door body 4, the ice breaking program is run again and the status of the door handle assembly 1 is determined;

[0129] If the ice breaking program is run more than twice and the door handle assembly 1 does not pop out of the opening on the vehicle door body 4, a fault alarm is issued.

[0130] If the ice-breaking program is run twice and still fails to solve the problem of the door handle assembly 1 not popping out, there may be other faults. At this time, issuing a fault alarm can remind the user to take other measures.

[0131] For example, see Figure 8 After receiving the door unlock command, the system determines whether the door handle assembly 1 pops out of the opening in the door body 4. If so, the process ends immediately. If not, the system further checks whether the ambient temperature meets the preset conditions. If so, the system initiates the ice-breaking process to break the ice. If not, a fault alarm is issued to alert the user to other faults with the concealed door handle. If the ice-breaking process is initiated twice and the door handle assembly 1 still fails to pop out of the opening in the door body 4, a fault alarm is issued to alert the user.

[0132] According to a third aspect of the present application, a vehicle door is further provided, comprising the aforementioned hidden door handle. The vehicle door provided in the embodiment of the present application has all the beneficial effects of the aforementioned hidden door handle, which will not be described in detail here.
