[0002] Vehicle interior safety design is a crucial aspect of ensuring the lives of passengers. Among these features, emergency door handles, also known as safety handles, are a fundamental and critical passive safety device that plays a vital role. Emergency door handles are purely mechanical or have a mechanical backup function, installed on the door trim panel. In extreme emergencies such as severe collisions, electrical system short circuits, or failures, conventional electric door locks or electronic switches may fail. In such situations, emergency door handles provide occupants with a physical way to open the door without relying on the vehicle's power supply, allowing them to quickly open the door from the inside for self-rescue or to assist with external rescue. They are an essential feature required by global automotive safety regulations.
[0003] For example, a door inner panel emergency grab handle structure and automobile disclosed in CN115288535A form the emergency grab handle through a cover and pull wire structure. However, in actual emergencies, occupants may have difficulty quickly locating the safety grab handle due to panic or dim lighting; external rescue personnel, unfamiliar with the vehicle structure, need to spend extra time finding the grab handle release point, delaying crucial rescue time; furthermore, although some vehicles have ambient lighting near the emergency grab handle, it is difficult to provide clear and sufficiently wide visual guidance for drivers and passengers in an emergency. Utility Model Content
[0004] In view of this, this utility model proposes a car door emergency handle cover assembly, a car door, and a vehicle. By setting a dedicated light guide, the light emitted by the point or line light source of the light-emitting part is efficiently captured and guided to the entire transparent panel area of the handle cover using the light guide path. The light is scattered at the interface between the light guide and the transparent panel through a design, so that the entire transparent panel becomes a luminous marking surface. In dim environments, it can provide clear, blind-spot-free overall visual guidance for drivers and passengers, covering the entire handle operation area, which greatly improves the identification speed and operation accuracy in emergency situations.

Detailed Implementation
[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0019] like Figure 1-5As shown, the vehicle door emergency handle cover assembly of this utility model is integrated into the door interior panel 1 as part of the vehicle's internal safety system. It provides clear, reliable and aesthetically pleasing visual guidance for drivers and passengers in emergency situations. Specifically, it includes the interior panel 1, handle cover 2, light-emitting part 3 and light guide part 4.
[0020] The interior panel 1 forms the main body of the inner surface of the door. Its surface can be covered with leather, fabric or plastic trim as required by the design. At the position corresponding to the emergency handle of the door, the interior panel 1 has a handle groove 101 specially formed or machined. The handle groove 101 provides space for accommodating and operating the emergency handle, and its size and shape are matched with the specific handle mechanism.
[0021] The handle cover 2 is designed to be installed within the handle groove 101. A key feature of the handle cover 2 is that it has a transparent panel, which is preferably made of optical-grade plastic, such as polycarbonate PC or polymethyl methacrylate PMMA, and has good light transmittance and sufficient mechanical strength. The handle cover 2 can be installed in the handle groove 101 by snap-fit connection, hinge, or other connection methods. It needs to trigger a mechanical door opening mechanism. One of the main functions of the handle cover 2 is to close part of the opening of the handle groove 101, which serves both aesthetic and dustproof purposes. At the same time, its transparent panel area serves as the final luminous indicator interface.
[0022] The light-emitting part 3 is the light source of the component and is fixedly installed on the structure of the interior panel 1. The light-emitting part 3 can be composed of one or more light-emitting diodes and their necessary driving circuits and mounting brackets. The light-emitting part 3 can also be modularly designed and installed as a whole. The light-emitting part 3 has one or more emitting ends for emitting specific colors, such as bright red, orange or white light. In this embodiment, the fixed position of the light-emitting part 3 is designed so that its emitting end can accurately dock with the light guide part 4, and the position should facilitate the layout of electrical wiring.
[0023] The light guide 4 is the core component for achieving efficient light transmission and light effect optimization. One end of the light guide 4 is physically connected to or closely close to the handle cover 2, and the other end is connected to the emitting end of the light-emitting part 3. Through this connection, a complete light guide path is formed between the light-emitting part 3, the light guide 4 and the transparent panel of the handle cover 2.
[0024] In this embodiment, after the light-emitting part 3 is powered on and lit, the light emitted from it is emitted from the emitting end and immediately enters the light guide part 4. The light guide part 4 can be made of an optical material with high light transmittance and low light loss. Its internal structure can efficiently guide the light to be transmitted along a preset path and minimize light energy loss. The light is conducted in the light guide part 4 and is finally guided and injected into the transparent panel of the handle cover 2. The transparent panel itself or its interface with the light guide part 4 can be designed with specific micro-textures, frosted surfaces or built-in scatterers, so that the light entering the panel is scattered inside, thereby breaking the total internal reflection condition and allowing the light to be uniformly transmitted from the entire surface of the transparent panel or the preset pattern area, becoming a bright surface light source.
[0025] In some embodiments, the interior panel 1 includes a panel 11 and a mounting member 12. The panel 11 has an opening, and the mounting member 12 is fixed to one side of the panel 11. The handle groove 101 is located on the mounting member 12 and is directly opposite the opening on the panel 11.
[0026] The panel 11 forms the main body of the interior surface facing the passenger compartment. It can be a large injection-molded part, and the surface is covered, sprayed or textured according to the overall vehicle interior design. At the position corresponding to the emergency handle mechanism of the door, an opening is pre-drilled on the panel 11. The size of the opening is slightly larger than the final required handle operation window. Its main function is to provide assembly space and operation channel for the subsequent installation parts 12 and handle mechanism.
[0027] The mounting component 12 is a component independent of the plate 11. It is usually made of engineering plastic with higher structural strength and better dimensional stability. The mounting component 12 can be fixed to the side of the plate 11 facing the door sheet metal, i.e. the back of the plate 11, by means of snap-fit, ultrasonic welding, screw fastening or bonding. One of the core functions of the mounting component 12 is to support and form the handle groove 101. The handle groove 101 is precisely formed on the mounting component 12, and its shape and size match the movement trajectory of the emergency handle body and the contour of the handle cover 2.
[0028] In some embodiments, the interior panel 1 is provided with a trim, and the trim and the transparent panel surface are on the same plane. After the components are installed in place, the transparent panel of the handle cover 2 is neither recessed below the interior panel surface nor protruding above it, but is integrated with the surrounding interior panel trim, so that the handle cover 2 will not protrude or be recessed, and will not affect the overall aesthetics of the interior trim.
[0029] In some embodiments, the handle cover 2 blocks part of the opening in the handle groove 101. The opening area of the handle groove 101 can be divided into two functional parts. One part is blocked by the handle cover 2 and serves as a static visual indication and decorative area. The other part of the unblocked opening remains open and serves as a dynamic operating channel, allowing fingers to be inserted to touch and operate the handle cover 2 located in the handle groove 101, thereby forming a clear guide.
[0030] In one specific embodiment, the mounting component 12 is provided with a fixing part 121 located outside the handle groove 101, and a gap is provided between the fixing part 121 and the interior panel 1 to form a mounting position, and the light-emitting part 3 is disposed on the mounting position.
[0031] The fixing part 121 is part of the main structure of the mounting part 12. It is located on the outside of the handle groove 101. The specific form of the fixing part 121 can be a boss, an ear with a mounting hole, or a specific snap-fit structure. The key point is that when the mounting part 12 is fixed to the back of the plate 11, a predetermined gap is formed between the mounting surface of the fixing part 121 and the interior panel 1 as a mounting position for installing the light-emitting part 3. The housing or bracket of the light-emitting part 3 can be fixed to the fixing part 121 by screws or snapped into the preset slot in the gap, so as to be securely set between the mounting part 12 and the plate 11.
[0032] In a specific embodiment, the light guide 4 includes a first light guide 41 and a second light guide 42. The first light guide 41 is embedded in the mounting member 12 and docks with the emitting end of the light-emitting part 3. The second light guide 42 is disposed on the handle cover 2 and cooperates with the first light guide 41 to form a passage. One end of the first light guide 41 is designed to directly dock with the emitting end of the light-emitting part 3. Its docking surface can be designed as a lens, a groove, or a specific angle to maximize the reception of light emitted from the light-emitting part 3 and achieve efficient light energy capture. One end of the second light guide 42 is disposed inside the handle cover 2, while the other end docks with the first light guide 41 in the optical path. This arrangement does not affect the rotation of the handle cover 2. At the same time, when the handle cover 2 is not rotating, the light beam can be sent into the second light guide 42.
[0033] In order to fix the first light guide 41, an embedding groove 102 is specially machined or formed at a specific position of the mounting member 12. The embedding groove 102 is a recessed structure or through hole with a precise design of shape and size, and its outline matches a specific part of the first light guide 41.
[0034] In some embodiments, the system further includes a vehicle power supply unit 5 and an independent power supply unit 6, which are connected in parallel to the light-emitting part 3 to supply power to the light-emitting part 3.
[0035] Specifically, the vehicle power supply unit 5 represents the vehicle's original main electrical system, which is connected to the vehicle's battery and body control module. Under normal circumstances, the vehicle power supply unit 5 provides working power to the light-emitting part 3 and is controlled by the logic of the BCM. For example, when the vehicle is unlocked, the door is opened, or a specific warning is triggered, the BCM will instruct the power supply line to supply power to the light-emitting part 3 to make it light up. Its brightness can be directly controlled to form an integrated or distinct ambient light.
[0036] Independent power supply unit 6 is specifically designed for the emergency handle lighting function. It is a backup power system independent of the vehicle's main electrical system. It can be a small-capacity capacitor, a rechargeable button battery / lithium battery module, or a supercapacitor. This unit is integrated inside or near the door trim module and has an independent charging management circuit. During normal vehicle operation, it receives trickle charging from the vehicle power supply unit 5 to maintain its own full charge.
[0037] When a vehicle experiences a severe collision, electrical short circuit, battery damage, or main wiring harness breakage, causing the vehicle's power supply unit 5 to completely fail or lose power, the independent power supply unit 6 connected in parallel to the circuit will immediately and automatically take over, continuing to supply power to the light-emitting unit 3. Because it is connected in parallel, no mechanical or electronic switches are required for switching, resulting in zero response time and ensuring that the lighting function will not extinguish in the event of any unexpected power outage.
[0038] The present invention relates to a car door, wherein the inner side of the car door is provided with the aforementioned emergency handle cover assembly. The emergency handle is integrated into the car door as a standard or high-end feature, which significantly improves the passive safety level and technological feel of the car door and even the entire vehicle.
[0039] The vehicle of this utility model includes the aforementioned car door. This vehicle can be any type of vehicle, such as a passenger car or commercial vehicle, and all side doors of the vehicle are equipped with this car door. In some safety-conscious vehicle models, even the inside of the trunk door can be fitted with an emergency escape indicator component based on a similar principle.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
