The end of the second pull rope 4212 away from the cable combination structure 422 is used to connect the door lock core.

[0070] The shapes of the second connecting head 452 and the third connecting head 453 can be matched with the shapes of the second connecting groove 4224 and the third connecting groove 4225, respectively. For example, if the second connecting head 452 and the third connecting head 453 are spherical structures, the second connecting groove 4224 and the third connecting groove 4225 can be grooves with spherical structures. If the second connecting head 452 and the third connecting head 453 are cylindrical structures, the second connecting groove 4224 and the third connecting groove 4225 can be grooves with cylindrical shapes.

[0071] In addition, one end of the first pull rope 4211 can rotate in the first connecting groove 4121 through the first connecting head 451, and the other end of the first pull rope 4211 can rotate in the second connecting groove 4224 of the first connecting rod portion 4222 through the second connecting head 452, and the second pull rope 4212 can rotate in the third connecting groove 4225 of the second connecting rod portion 4223 through the third connecting head 453, so that the pull rope member 421 can effectively transmit the pulling force from the operator outside the door to the door lock core, avoiding the loss of pulling force in the area between the two ends of the pull rope member 421, and accordingly improving the rapidity of unlocking the door relative to the vehicle body.

[0072] In the embodiment, the unlocking principle of the vehicle door is that the covering structure 410 is detached from the handle outer cover 100, an operator outside the vehicle door applies an outward pulling force to the covering structure 410, the pulling force drives the first connecting head 451, the first pull rope 4211, the second connecting head 452, the pull rope combination structure 422, the third connecting head 453, and the second pull rope 4212 to move, in the process, the torsional spring 424 is passively deformed under the rotating action of the pull rope combination structure 422 to drive the vehicle door lock cylinder to separate from the lock hole of the vehicle body to realize the unlocking action of the vehicle door relative to the vehicle body; after the vehicle door is unlocked, the operator no longer applies the pulling force, at this time, since the two ends of the torsional spring 424 are connected to the pull rope combination structure 422 and the rotating shaft seat 440 respectively, the pull rope combination structure 422 drives the pull rope combination structure 422 to rotate relative to the axis of the rotating shaft 423 under the elastic reset force of the torsional spring 424 to reset.

[0073] Optionally, in combination with Figure 2 and Figure 4 As shown in the drawings, the first unlocking assembly 400 further includes a second guide structure 460, the second guide structure 460 includes a mounting seat 461 and a limiting tube 462, the mounting seat 461 is arranged on the handle base 300 and is located on one side of the pull rope combination structure 422, the mounting seat 461 has a mounting groove, the limiting tube 462 is detachably mounted in the mounting groove, the limiting tube 462 is sleeved on a part of the pull rope member 421, and the part of the pull rope member 421 is used to move in the limiting tube 462.

[0074] Specifically, the mounting seat 461 can be fixedly mounted on the handle base 300, for example, the two can adopt an integrated structure, which can improve the mounting stability of the limiting tube 462 on the mounting seat 461.

[0075] The shape of the mounting groove on the mounting seat 461 matches the shape of the limiting tube 462, the limiting tube 462 can be detachably mounted in the mounting groove in a clamping manner, and the detachability of the limiting tube 462 and the mounting seat 461 in the later maintenance stage can be improved.

[0076] The second pull rope 4212 of the pull rope member 421 is arranged in the limiting tube 462 and can move in the limiting tube 462 under the action of the pulling force.

[0077] In the embodiment, since the second pull rope 4212 of the pull rope member 421 is arranged in the limiting tube 462 and the limiting tube 462 is fixed on the handle base 300, the cooperation of the mounting seat 461 and the limiting tube 462 can not only limit the second pull rope 4212 of the pull rope member 421 on the handle base 300 to prevent the second pull rope 4212 from being disordered, but also will not hinder the movement of the second pull rope 4212 under the action of the pulling force.

[0078] Optionally, in combination with Figure 2 、 Figure 4 、 Figure 7 As shown in the figure, the pulling mechanism 420 further comprises a sealing tube 470, which is sleeved on at least part of the outer of the pull rope 421 between the cable combination structure 422 and the limiting tube 462.

[0079] Specifically, the sealing tube 470 can be a telescopic tube structure. Since the sealing tube 470 is sleeved on at least part of the outer of the second pull rope 4212 between the cable combination structure 422 and the limiting tube 462, and the aperture of the sealing tube 470 is slightly larger than the aperture of the limiting tube 462, the connection between the second pull rope 4212 and the limiting tube 462 can be sealed by the sealing tube 470 to prevent impurities from the outside from entering the limiting tube 462 from the connection between the second pull rope 4212 and the limiting tube 462, so as to ensure that the second pull rope 4212 of the pull rope 421 can move smoothly in the limiting tube 462, improve the smoothness of the second pull rope 4212 moving in the limiting tube 462, not only can prolong the service life of the pull rope 421, but also can quickly unlock the door when the vehicle has an accident, saving the rescue time of the vehicle personnel to get away from the vehicle.

[0080] Optionally, in combination with Figure 2 As shown in the figure, the first unlocking assembly 400 further comprises a plurality of third guide structures 480, which are spaced around the edge of the handle base 300, and the second pull rope 4212 of the pull rope 421 passes through the plurality of third guide structures 480.

[0081] Specifically, the third guide structure 480 can have a third guide groove, the size of which is slightly larger than the size of the second pull rope 4212, and the third guide groove can be an arc-shaped groove or a ring-shaped groove, so as to ensure that the second pull rope 4212 can move smoothly in the third guide groove.

[0082] The third guide structure 480 can be a block structure, a plate structure, a column structure, etc. with a third guide groove, which is not limited here.

[0083] Optionally, in combination with Figure 9 As shown in the figure, the emergency unlocking device comprises a second unlocking assembly 500, the second unlocking assembly 500 comprises a capacitive element, the capacitive element is arranged on the inner side of the handle outer cover 100, the capacitive element is used for electrically connecting with a vehicle door control system, and the capacitive element is used for controlling the vehicle door lock cylinder to be separated from the lock hole of the vehicle body through the vehicle door control system.

[0084] Specifically, the capacitive element can be installed on the inner side wall of the handle outer cover 100 and can be located at the upper part of the hand pocket lamp cover 210 in the hand pocket lamp assembly 200 to avoid interference of the capacitive element with the installation of the hand pocket lamp cover 210 between the handle base 300 and the handle outer cover 100. The vehicle door control system drives the vehicle door lock cylinder to be separated from the lock hole of the vehicle body by an electric manner to unlock the vehicle door, which is a prior art. As long as a technical solution can be achieved to control the vehicle door to be unlocked by an electric manner according to a signal that the capacitive element detects that a finger is inserted into the hand pocket lamp assembly 200 to be close to the capacitive element, the technical solution is suitable for the present technical solution, and is not limited here.

[0085] In the optional embodiment, when the vehicle does not fail or although a failure occurs, the internal power supply of the vehicle is still normal, the capacitive element is used to control the vehicle door lock cylinder to be separated from the lock hole of the vehicle body by an electric manner through the vehicle door control system when it is sensed that a finger of an operator is inserted into the hand pocket lamp assembly 200 to achieve unlocking of the door lock of the vehicle door, and then a pulling force is applied to the vehicle door to open the vehicle door to get on the vehicle.

[0086] Optionally, in combination with Figure 9 As shown, the emergency unlocking device includes a third unlocking assembly 600, the third unlocking assembly 600 includes an unlocking switch, the unlocking switch is arranged on the handle outer cover 100, the unlocking switch is electrically connected with the vehicle door control system, and the vehicle door control system is used to control unlocking of the door lock of the vehicle door.

[0087] Specifically, the unlocking switch can be a key switch, a knob switch or a toggle switch.

[0088] An installation hole can be formed on the handle outer cover 100, and part of the unlocking switch is embedded in the installation hole, and the other part of the unlocking switch is located on the inner side of the handle outer cover 100. The unlocking switch can be installed on the inner side wall of the handle outer cover 100, can be installed on the outer side wall of the handle base 300 facing the handle outer cover 100, or can be independently installed between the handle outer cover 100 and the handle base 300.

[0089] In the optional embodiment, when the vehicle does not fail or although a failure occurs, the internal power supply of the vehicle is still normal, the owner or passenger operates the unlocking switch, controls the vehicle door lock cylinder to be separated from the lock hole of the vehicle body by an electric manner through the vehicle door control system to achieve unlocking of the door lock of the vehicle door, and then a pulling force is applied to the vehicle door to open the vehicle door to get on the vehicle.

[0090] For example, when the vehicle has the above-mentioned rollover, collision and other failures, there are three kinds of emergency unlocking modes, the first kind, the operator outside the vehicle applies a pulling force to the covering structure 410, and through the cooperation of the covering structure 410 and the pulling mechanism 420, the pulling force is applied to the lock hole of the door lock core to separate the door lock core from the lock hole of the vehicle door, and the door is opened under the pulling force of the hand of the person outside the vehicle. The second kind, when the fingers of the operator are inserted into the hand hole lamp cover 210 of the hand hole lamp assembly 200, and the capacitive switch is in a non-contact mode, the capacitive switch cooperates with the vehicle door control system to control the door lock core to separate from the lock hole of the vehicle body by the vehicle door control system in an electric mode, so as to unlock the door lock core, and the door can be opened under the pulling action of the fingers of the operator. The third kind, through manual operation of the unlocking switch outside the vehicle door, the unlocking switch transmits a signal to the vehicle door control system to control the door lock core to separate from the lock hole of the vehicle body by the vehicle door control system in an electric mode, so as to unlock the door lock core, and the door can be opened under the pulling action of the fingers of the operator. When the vehicle has rollover, collision and other failures, at least one of the above-mentioned unlocking modes can be used to realize the unlocking and opening of the door relative to the vehicle body.

[0091] Optionally, in combination with Figure 9 As shown, the hand hole lamp assembly 200 comprises a hand hole lamp cover 210, a hand hole lamp light emitting component 230 and a hand hole lamp bracket 240, the hand hole lamp light emitting component 230 is arranged between the hand hole lamp cover 210 and the hand hole lamp bracket 240, and the hand hole lamp assembly 200 is installed on the handle base 300.

[0092] Specifically, the hand hole lamp light emitting component 230 can be arranged on the hand hole lamp bracket 240 in the following manner, for example, the hand hole lamp bracket 240 has a first mounting cavity, the hand hole lamp light emitting component 230 is provided with a first mounting structure, and the hand hole lamp light emitting component 230 is fixed in the first mounting cavity of the hand hole lamp bracket 240 through the first mounting structure; the first mounting structure can be adhesion, bolt fastener, buckle and the like.

[0093] The hand hole lamp light emitting component 230 can be an LED light plate for emitting light when powered on, which can serve as a light source of the hand hole lamp light emitting component 230.

[0094] The hand hole lamp assembly 200 can further comprise a hand hole lamp light distribution mirror 220, which can be arranged between the hand hole lamp cover 210 and the hand hole lamp bracket 240; specifically, the hand hole lamp light distribution mirror 220 is arranged between the hand hole lamp cover 210 and the hand hole lamp light emitting component 230.

[0095] The hand-held light distribution lens 220 can be made of diffused glass, which can be formed by pressing transparent glass, for example, by combining multiple special prisms and lenses. The hand-held light distribution lens 220 can also be made of transparent resin material, or a light guide plate can be used to achieve a light guiding function. The hand-held light distribution lens 220 is located on the side of the hand-held light-emitting component 230 facing the hand-held light cover 210, and is used to control the direction and brightness of the light emitted by the hand-held light-emitting component 230. For example, it can refract the light emitted by the hand-held light-emitting component 230, and the refracted light is reflected after passing through the hand-held light cover 210 to produce light within the hand-held light cover 210, so as to provide a position indicator and make the door handle assembly visible relative to the door body in low-light environments.

[0096] The hand-held light assembly 200 is mounted on the handle base 300. Specifically, the hand-held light cover 210 of the hand-held light assembly 200 can be directly assembled and connected to the handle base 300, or the hand-held light cover 210 can be indirectly assembled and connected to the handle base 300 through other components. Other components in the hand-held light assembly 200, such as the hand-held light emitting component 230 and the hand-held light bracket 240, can be mounted on the handle base 300 through the hand-held light cover 210.

[0097] The hand-held lamp shade 210 can be structured in conjunction with the light refracted by the hand-held lamp lens 220 to form a luminous pattern on the inner side of the hand-held lamp shade 210:

[0098] Exemplary illustration, in conjunction with Figure 10 As shown, the hand-shaped lamp cover 210 includes a transparent substrate 211, a pattern layer 212, and a color layer 213. The color layer 213 is disposed on the outer side of the transparent substrate 211, and the pattern layer 212 is disposed on the inner side of the transparent substrate 211.

[0099] Specifically, the pattern layer 212 can be formed on the inner wall of the transparent substrate 211 through processes such as laser engraving, laser carving, and lamination. When light refracted by the hand-held lamp's light distribution lens 220 shines on the pattern layer 212, a luminous pattern can be formed on the inner side of the hand-held lamp's face mask 210. The color layer 213 can achieve a light-transmitting effect by using PVD technology, spraying, or film application. For example, a PVD process can be used to mold a coating, such as bright silver indium material, onto the outer wall of the transparent substrate 211.

[0100] The hand-held lamp's light-emitting component 230 emits light toward the hand-held lamp's light distribution lens 220, which is used to adjust the direction and brightness of this light (see [reference to another document] for the adjusted light direction). Figure 5The light rays are refracted by the light refraction lens 220, and then the light rays are transmitted to the pattern layer 212, and then the light rays are reflected at the color layer 213 after passing through the pattern layer 212, and the emitted light rays cooperate with the pattern layer 212 to form a light-emitting pattern on the inner side of the hand hole lamp cover 210.

[0101] The PVD process refers to a technology of using physical methods to vaporize the surface of a certain substance into gaseous atoms, molecules or partially ionized ions under vacuum conditions, and then depositing thin film materials with certain special functions on the surface of the transparent base material 211 through low-pressure gas (or plasma) processes. Under the PVD technology, the substances used to prepare thin film materials are collectively referred to as PVD coating materials. After years of development, PVD technology has become the mainstream coating method, mainly including sputtering coating and vacuum evaporation coating, which will not be described here.

[0102] The hand hole lamp cover 210 cooperates with the light rays refracted by the light refraction lens 220 to form a light-emitting pattern on the inner side of the hand hole lamp cover 210, which can include breathing patterns, flowing water patterns, etc., and can improve the technological sense of the vehicle.

[0103] In the embodiment, since the hand hole lamp cover 210 cooperates with the light rays refracted by the light refraction lens 220 to form a light-emitting pattern on the inner side of the hand hole lamp cover 210, compared with the related art, the lighting mode of the semi-hidden outer handle is basically a point or strip light source effect, and the lighting mode of the light source is relatively single and lacks beauty. In the hand hole lamp assembly 200, the pattern layer 212 has a high degree of freedom in forming patterns, which not only increases the eye-catching effect of the vehicle door handle assembly, but also helps the vehicle owner to quickly find the vehicle door handle assembly in a place with relatively dark ambient light, improves the user experience of the vehicle owner, and improves the technological sense of the vehicle.

[0104] For example, when the driver needs to open the door again, the driver can quickly determine the specific position of the vehicle door handle assembly relative to the door or the vehicle according to the bright light or even the light-emitting pattern generated by the hand hole lamp assembly 200, so as to play a role in position indication and eye-catching, and accordingly improve the user experience of the vehicle owner.

[0105] Moreover, when the vehicle inside personnel is in the parking phase and other vehicles collide in the above light dark place, the operating personnel outside the vehicle can quickly determine the specific position of the faulty vehicle door handle assembly through the light and even the light pattern generated by the above hand pocket lamp assembly 200, and the operating personnel based on the light generated by the hand pocket lamp assembly 200 as illumination, can help the vehicle door to be unlocked manually through the above first unlocking assembly 400, second unlocking assembly 500, third unlocking assembly 600, so as to assist the vehicle inside personnel to quickly escape from the above faulty vehicle, greatly shorten the rescue time of the personnel in the faulty vehicle, and accordingly improve the safety of the vehicle in emergency. In short, the door handle assembly in the embodiment has the position indication and eye-catching function, the emergency unlocking function, so as to improve the user experience of the vehicle.
