[0031] Various specific embodiments of the present application will be described below with reference to the accompanying drawings which constitute a part of this specification. It should be understood that, where possible, the same or similar reference numerals used in this application refer to the same components.

[0032] Figure 1a is a perspective view of a door handle 100 according to an embodiment of the present application, the door handle 100 is used to be installed on a vehicle door 10 (see Figure 2a to Figure 2d ), the owner or passenger can open the door 10 by pulling the door handle 100. Figure 1b yes Figure 1a The cross-sectional view of the door handle 100 along the AA line is shown, and an enlarged view of a part (i.e., the part in the rectangular frame) in the cross-sectional view is shown. Figure 1a and Figure 1b The structure of the door handle 100 will be described.

[0033] like Figure 1a and Figure 1b As shown, the vehicle door handle 100 includes a handle base 101 and a handle grip 102. The handle grip 102 is movably connected to the handle base 101 so as to have an extended position and a retracted position relative to the handle base 101. Figure 1b10. The handle 102 is shown in the retracted position, and the handle 102 can move along the direction A to reach the extended position (not shown in the figure) from the retracted position. Although not shown in the figure, the handle 102 in the extended position can move in the direction opposite to the direction A to return from the extended position to the retracted position. When the handle 102 moves to the extended position, the owner or the passenger can pull the handle 102 to open the vehicle door 10. The handle 102 has a handle body 108 and a peripheral edge 106, and the peripheral edge 106 surrounds the handle body 108 and extends parallel to the moving direction of the handle 102.

[0034] The door handle 100 further includes a heating member 103 connected to the handle base 101. The heating member 103 extends a distance parallel to the moving direction of the handle grip 102, thereby having a width direction. Therefore, the heating member 103 provides a heating space having a width parallel to the moving direction of the door handle 102. The heating member 103 has an annular opening, so that when the handle grip 102 is in the retracted position, the heating member 103 surrounds the periphery 106 of the handle grip 102, and an area 107 is spaced between the heating member 103 and the periphery 106. The area 107 is at least partially located in the heating space, and is thereby at least partially heated by the heating member 103. Thus, as will be further described below, at least a portion of the ice formed in the area 107 can be heated and melted. Figure 1a As shown, in the embodiment shown in the present application, the heating member 103 is connected to the end surface 111 of the handle base 101 close to the handle handle 102. When the door handle 100 is installed on the vehicle door 10, the end surface 111 faces the door metal outer panel body 201 (such as Figure 2b In other embodiments, the heating member 103 may be connected to other locations of the handle base 101 as long as the heating member 103 is able to surround the periphery 106 of the handle grip 102.

[0035] Figure 2a Shows installation Figure 1a and Figure 1b FIG. 1 is a partial perspective view of an embodiment of a vehicle door 10 showing a door handle 100 . Figure 2b yes Figure 2a FIG. 1 is a partial perspective view of the vehicle door 10 from another angle. Figure 2c yes Figure 2a and Figure 2b An exploded view of the vehicle door 10 in FIG. Figure 2d yes Figure 2a The sectional view of the door along the BB line and the enlarged view of the part (i.e., the part in the rectangular frame) in the sectional view. For the convenience of explanation, Figure 2dOnly the handle grip 101 and the heating member 103 of the door handle 100 are shown, and the handle base 102 is omitted. Figure 2a to Figure 2d A vehicle door 10 on which the vehicle door handle 100 according to the present application is installed is described.

[0036] The vehicle door 10 includes a vehicle door handle 100 and a metal outer panel 200. The metal outer panel 200 includes a metal outer panel opening 203. The metal outer panel 200 is bent toward the inside of the vehicle door at the metal outer panel opening 203 to form a metal outer panel flange 202, so that the metal outer panel 200 includes a metal outer panel body 201 and a metal outer panel flange 202, and the metal outer panel flange 202 defines the metal outer panel opening 203. When the handle handle 102 is in the extended position, the handle handle 102 is located on the outside of the metal outer panel 200, so that the vehicle owner or passengers can pull the handle handle 102 to open the vehicle door 10. When the handle handle 102 is in the retracted position, the handle handle 102 is located in the metal outer panel opening 203, so that the vehicle owner or passengers cannot pull the handle 102. Figure 2a to Figure 2d In the illustrated embodiment, the metal outer plate flange 202 is disposed in the heating space provided by the heating member 103, so that the entire width of the metal outer plate flange 202 can be heated by the heating member 102. The metal outer plate flange 202 is disposed so that the heating member 103 surrounds the metal outer plate flange 202. Furthermore, when the handle 102 is located in the metal outer plate opening 203, the metal outer plate flange 202 is interposed between the heating member 103 and the periphery 106 of the handle 102, and the metal outer plate flange 202 surrounds the periphery 106 of the handle 102, and is separated from the periphery 106 of the handle 102 by a gap 104. When the handle 102 is in the retracted position, the metal outer plate flange 202 heated by the heating member 103 further heats at least a portion of the gap 104 between the metal outer plate flange 202 and the periphery 106 of the handle 102. As described further below, the metal outer panel flange 202 heats at least a portion of the gap 104 such that at least a portion of ice formed in the gap 104 is melted.

[0037] Since there is an area 107 between the periphery 106 of the handle 102 and the heating member 103, water (e.g., in rainy or snowy days or after washing the car) may enter the area 107. In low temperature conditions (e.g., in winter), the water entering the area 107 may freeze. When ice connects the handle 102 and the heating member 103, the handle 102 cannot be moved from the retracted position to the extended position, which causes the owner or passenger to be unable to pull the handle 102 to open the door 10, affecting the use and travel of the vehicle by the owner or passenger. However, since the heating member 103 is provided in the door handle 100 according to the present application to provide a heating space, and the area 107 is at least partially located in the heating space, at least part of the ice in the area 107 can be heated and melted, thereby disconnecting the ice from the handle 102 and the heating member 103, so that the handle 102 can be moved from the retracted position to the extended position. Therefore, the use of the vehicle door handle 100 according to the present application can prevent the handle 101 from being frozen and unable to move from the retracted position to the extended position, ensuring that the vehicle door 10 can be opened. In addition, since the heating space provided by the heating component 103 in the present application has a certain width along the movement direction parallel to the vehicle door handle 102, the heating component 103 in the present application provides a larger heating area, so that the ice in the melting area 107 can be quickly heated.

[0038] When the metal outer plate flange 202 is arranged between the periphery 106 of the handle 102 and the heating member 103, after water enters the gap 104 between the periphery 106 of the handle 102 and the metal outer plate flange 202, if the ice formed connects the handle 102 and the metal outer plate flange 202, the handle 102 cannot move from the retracted position to the extended position. Since the metal outer plate flange 202 is arranged in the heating space and heated by the heating member 103, at least part of the ice in the gap 104 can be melted by heating the heated metal outer plate flange 202, thereby avoiding the situation that the handle 102 cannot be extended due to freezing, which is conducive to smoothly opening the door and ensuring the normal use of the vehicle. And since the heating space provided by the heating member 103 in the present application has a certain width along the movement direction parallel to the door handle 102, the entire width of the metal outer plate flange 202 is heated in the heating space, so that the metal outer plate flange 202 can quickly heat and melt the ice in the gap 104.

[0039] Compared with the handle 102 made of plastic material, the metal outer plate flange 202 has better thermal conductivity. Therefore, compared with the method of melting the ice in the gap 104 by heating the handle 102, the method of melting the ice in the gap 104 by heating the metal outer plate flange 202 in the present application can provide higher thermal conductivity efficiency, thereby accelerating the melting of the ice in the gap 104. The present application cleverly sets the positions of the heating component 103 and the metal outer plate flange 202, so that the metal outer plate flange 202 can be used to transfer the heat generated by the heating component 103 to the ice that needs to be melted.

[0040] In addition, compared with the method of using an independent heating component, the present application assembles the heating component 103 onto the door handle 100, so that the vehicle has a higher degree of integration, thereby making vehicle production more efficient and convenient, and the vehicle production cost is lower.

[0041] like Figure 2d As shown in FIG. 1 , there is a distance 105 between the heating member 103 and the metal outer plate flange 202. In the process of installing the door handle 100 on the vehicle door 10, the distance 105 enables the position of the door handle 100 to be adjusted, thereby facilitating the installation of the door handle 100 on the vehicle door 10. Due to the existence of the distance 105, the heat of the heating member 103 is transferred to the metal outer plate flange 202 with air as the medium. Therefore, when setting the distance 105, the needs of installing the door handle 100 and the efficiency of heat transfer are considered at the same time, and the installation of the door handle 102 is facilitated, and the efficient transfer of the heat of the heating member 103 to the metal outer plate flange 202 is ensured.

[0042] Figure 3a yes Figure 1a and Figure 1b A three-dimensional view of the heating component 103 in FIG. Figure 3b yes Figure 3a A three-dimensional view of the heating member 103 at another angle. Figure 3c yes Figure 3a An exploded view of the heating member 103 in FIG. Figure 3d yes Figure 3b The cross-sectional view of the heating member 103 along the CC line and the enlarged view of a part of the cross-sectional view (i.e., the part in the rectangular frame). Figures 3a to 3d One embodiment of the heating member 103 is described.

[0043] The heating member 103 includes a heating unit 160. The heating unit 160 includes a heating sheet 153, and the heating sheet 153 has a width to define the width direction of the heating member 103, for providing the heating space having a width parallel to the moving direction of the handle 102 as described above. The heating sheet 153 surrounds the periphery 106 of the handle 102 to form a ring with an opening, and an area 107 is spaced between the heating sheet 153 and the periphery 106 of the handle 102, and the heating sheet 153 can heat at least a portion of the area 107 to melt at least a portion of the ice in the area 107. When the vehicle door handle 100 is mounted on the vehicle door 10, the heating sheet 153 surrounds the metal outer plate flange 202, and the metal outer plate flange 202 is located in the heating space having a width provided by the heating sheet 153. Therefore, the heating plate 153 can heat the metal outer plate flange 202 over the entire width of the metal outer plate flange 202 (i.e., from the metal outer plate body 201 to the free end of the metal outer plate flange 202). Compared with the embodiment using the heating wire, the heating plate 153 provides a larger heating area, thereby improving the heating efficiency, which is conducive to accelerating the melting of ice in the area 107 or the gap 104.

[0044] The heating unit 160 further includes a heating lip 157, which surrounds the heating sheet 153 and extends away from the opening of the heating sheet 153 at an angle to the heating sheet 153. The heating lip 157 is used to face the metal outer plate body 201 to heat the metal outer plate body 201. The heating of the metal outer plate body 201 by the heating lip 153 is conducive to increasing the temperature at the metal outer plate flange 202, thereby further improving the heating efficiency and accelerating the melting of ice in the gap 104. Although the present application shows that the heating member 103 includes a heating sheet 153 and a heating lip 157, which are used to heat the metal outer plate flange 202 and the metal outer plate body 201 respectively, it should be understood that in another embodiment, the heating member 103 is configured to have only a heating sheet 153 for heating the metal outer plate flange 202. The heating member 103 including only the heating sheet 153 is sufficient to heat the metal outer plate flange 202, so that the metal outer plate flange 202 can melt the ice in the gap 104 after being heated.

[0045] The heating member 103 further includes a housing 150, which is made of plastic and defines a cavity 154. The cavity 154 is configured to accommodate the heating unit 160 so as to fix the heating unit 160 in the cavity 154. The housing 150 includes a mounting member 151 and a cover 152, the mounting member 151 is mounted to the handle base 101, and the cover 152 is sealed and connected with the mounting member 151 in a suitable manner to seal the cavity 154, so that the heating unit 160 is sealed in the cavity 154. The heating plate 153 and the heating lip 157 are sealed in the cavity 154 so as to prevent water from contacting the heating plate 153 and the heating lip 157, thereby avoiding failure of the heating plate 153 and the heating lip 157. In one embodiment, the cover 152 and the mounting member 151 are connected by laser welding. Laser welding makes the sealing of the housing 150 the best, and makes the production efficiency of the heating member 103 higher, and laser welding makes the deformation of the cover 152 and the mounting member 151 smaller.

[0046] The cover 152 and the mounting member 151 are configured to adapt to the shape of the heating unit 160 so as to accommodate the heating unit 160. Figure 3d As shown in , the cover 152 has a first portion corresponding to the heating sheet 153 and a second portion corresponding to the heating lip 157. When the door handle 100 is mounted to the vehicle door 10, the first portion of the cover 152 is located between the heating sheet 153 and the metal outer panel flange 202, and the second portion is located between the heating lip 157 and the metal outer panel body 201. In one embodiment, the heating sheet 153 and the heating lip 157 are respectively bonded to the mounting member 151 so that the heating unit 160 is fixed in the cavity 154. The cover 152 is designed to have a small thickness so that the cover 152 can transfer the heat of the heating sheet 153 and the heating lip 157 to the metal outer panel body 201 and the metal outer panel flange 202 to melt the ice in the gap 104. The thickness of the cover 152 is much smaller than the thickness of the handle 102. Therefore, even if the heat generated by the heating unit 160 in the present application must first be conducted through the cover 152 before reaching the metal outer plate flange 202, compared with the method of melting the ice in the gap 104 by heating the handle 102, the present application can still provide higher thermal conductivity efficiency and accelerate the melting of ice in the gap 104.

[0047] like Figure 3c and Figure 3d As shown in , the cover 152 further includes limiting structures 155 and 156, wherein the limiting structure 155 is located at the free end of the first portion of the cover 152 corresponding to the heating plate 153, and the limiting structure 156 is located at the free end of the second portion of the cover 152 corresponding to the heating lip 157. The limiting structures 155 and 156 are used to limit the position of the heating unit 160 in the cavity 154. In one embodiment, the mounting member 151 and the cover 152 are sealed and connected (for example, laser welded) at the limiting structures 155 and 156.

[0048] In one embodiment, the heating plate 153 and the heating lip 157 are integrally formed so that the heating unit 160 has a one-piece construction, thereby facilitating controlling the heating unit 160 to perform a heating operation. Figure 4a and Figure 4b An embodiment of manufacturing an integrated heating unit 160 is shown. In this embodiment, the heating member 160 has an initial planar shape, and is partially bent to form a heating plate 153 and a heating lip 157. Specifically, Figure 4a The heating member 160 is shown in a planar form, and a plurality of notches 161 are provided on one edge of the heating member 160 , so that the portion between adjacent notches 161 can be bent. Figure 4b FIG. 1 shows the shape of the heating member 160 after the portion between the plurality of notches 161 is bent. Figure 4b As shown, at this time, the bent portion constitutes the heating plate 153, and the unbent portion constitutes the heating lip 157. In other embodiments, the notch 161 may be replaced by a crack, for example.

[0049] This application has at least the following technical effects:

[0050] 1. The heat generated by the heating member 103 can melt at least part of the ice in the area 107 between the handle 102 and the heating member 103, thereby preventing the handle 102 from being frozen and unable to be extended. Therefore, it is ensured that the vehicle door 10 can be opened normally and the vehicle can be used normally.

[0051] 2. The heat generated by the heating member 103 can melt at least part of the ice in the gap 104 between the handle 102 and the metal outer plate flange 202, thereby preventing the handle 102 from being unable to extend due to freezing to the metal outer plate flange 202. Therefore, it is ensured that the vehicle door 10 can be opened normally and the vehicle can be used normally.

[0052] 3. The present application cleverly arranges the positions of the heating component 103 and the metal outer plate flange 202, and takes advantage of the good thermal conductivity of the metal outer plate flange 202 to heat the metal outer plate flange 202 using the heating component 103 to melt the ice in the gap 104 between the handle 102 and the metal outer plate flange 202, thereby improving the thermal conductivity efficiency and accelerating the melting of the ice in the gap 104 between the handle 102 and the metal outer plate flange 202.

[0053] 4. The present application uses a heating sheet 153, so that a heating space with a certain width can be provided. Therefore, the present application can provide a larger heating area, thereby improving the heating efficiency and accelerating the melting of ice in the area 107 between the handle 102 and the heating member 103. When the metal outer plate flange 202 is located in the heating space, the heating space with a certain width heats the entire width of the metal outer plate flange 202. Therefore, the present application provides a larger heating area for the metal outer plate flange 202, thereby improving the heating efficiency, which is conducive to accelerating the melting of ice in the gap 104 between the metal outer plate flange 202 and the handle 102.

[0054] 5. The present application seals the heating unit 160 in the housing 150 to prevent water from contacting the heating unit 160 and causing the heating unit 160 to fail.

[0055] 6. The present application assembles the heating component 103 onto the door handle 100 , so that the degree of integration of the vehicle is higher, thereby making vehicle production more efficient and convenient, and reducing vehicle production costs.
