Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] The terms "first," "second," etc., used in the specification and claims of this invention are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0039] It should be understood that the phrase "some embodiments" throughout the specification means that a specific feature, structure, or characteristic related to an embodiment is included in at least one embodiment of the invention. Therefore, "some embodiments" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0040] The following detailed description of a handrail, vehicle, and vehicle warning method provided by the present invention is illustrated through specific embodiments.

[0041] Figure 1 A schematic diagram of a handrail according to an embodiment of the present invention is shown, with reference to... Figure 1This invention provides a handrail, which includes a handrail body 1 and a light-emitting ring 2. The handrail body 1 is fixedly connected to the B-pillar of a vehicle. The light-emitting ring 2 is sleeved on the handrail body 1 and fixedly connected to the handrail body 1. The light-emitting ring 2 is electrically connected to the vehicle's control system and emits indicator light to indicate the external working conditions of the vehicle.

[0042] In this embodiment, the handrail body 1 is the main structure of the handrail. The handrail body 1 is used for fixed connection to the B-pillar of the vehicle. The fixed connection method includes, but is not limited to, assembly connection, welding, etc., which are not limited in this embodiment. When getting on and off the vehicle, passengers can use the handrail on the B-pillar for leverage. Especially for some models with high chassis height, such as MPVs (Multi-Purpose Vehicles) and SUVs (sports utility vehicles), passengers' feet cannot easily touch the ground when getting on and off the vehicle. In this case, they can use their hands to hold the handrail for leverage to achieve the action of getting on and off the vehicle, thereby helping passengers get on and off the vehicle more easily and improving the passenger's driving and riding experience.

[0043] To facilitate passenger gripping, the handrail body 1 can be configured as a long rod-like structure or a long handle-like structure. The size of the handrail body 1 should not be too large to avoid situations where passengers' hands cannot fully grip it. In some embodiments, the surface of the handrail body 1 can be configured as a rough surface, or an anti-slip structure can be provided on the surface of the handrail body 1. The anti-slip structure can be designed as a dotted or linear convex or concave structure. The rough surface or anti-slip structure can increase the friction between the handrail body 1 and the passenger's hand, preventing the passenger's hand from slipping off the handrail body 1, thereby improving the safety of passengers during boarding and alighting.

[0044] The light-emitting ring 2 can be made of components such as LEDs (Light Emitting Diodes), which can convert electrical energy into light energy. The light-emitting ring 2 is fitted onto the armrest body 1 and fixedly connected to it. The fixing method includes, but is not limited to, assembly connection, adhesive connection, snap-fit ​​connection, etc., which are not limited in this embodiment of the invention. The light-emitting ring 2 can be fitted onto any part of the armrest body 1. Since the area where passengers hold the ring is usually concentrated in the middle area of ​​the armrest body 1, in this embodiment, the light-emitting ring 2 can be positioned away from the middle area of ​​the armrest body 1 to avoid frequent contact between passengers' hands and the light-emitting ring 2, thus affecting its luminous effect. The light-emitting ring 2 is electrically connected to the vehicle's control system. The control system is used to monitor, adjust, and optimize various vehicle performance characteristics to ensure that the vehicle maintains its optimal state under various driving conditions. The control system mainly includes an electronic control unit, sensors, and actuators. Sensors are responsible for sensing various status information of the vehicle and transmitting this information to the ECU (Electronic Control Unit). The ECU processes this information according to a preset control program and issues corresponding control commands to the actuators, thereby achieving precise control of various vehicle components.

[0045] Because collisions between vehicle doors and side-moving non-motorized vehicles or motorized vehicles are relatively frequent when vehicle doors open, some vehicles are equipped with warning devices inside the vehicle to alert passengers to the external driving conditions when they disembark, thus preventing collisions. However, the installation of these warning devices increases the cost of vehicle components and occupies interior space, hindering vehicle optimization and improvement. Therefore, in this embodiment of the invention, the luminous ring 2 on the handrail is electrically connected to the vehicle's control system. When a passenger needs to open the door, the control system can control the luminous ring 2 to emit an indicator light. This indicator light can alert passengers to the external driving conditions, including both driving conditions and environmental conditions. Driving conditions refer to the impact of dynamic obstacles such as motorized and non-motorized vehicles, while environmental conditions refer to the impact of static obstacles such as streetlights, signs, and buildings. The indicator light can refer to the color of the light emitted by the light-emitting ring 2. For example, the light-emitting ring 2 emits different colors of light to indicate the working conditions outside the vehicle. The indicator light can also refer to the way the light-emitting ring 2 emits light. For example, the light-emitting ring 2 flashes at different frequencies to indicate the working conditions outside the vehicle. This embodiment does not limit this.

[0046] In some embodiments, the control system can control the color of the light emitted by the luminous ring 2. For example, if the external conditions are safe, the control system can control the luminous ring 2 to emit green light; if the external conditions are dangerous, the control system can control the luminous ring 2 to emit red light. This allows passengers to understand the external situation based on the light color. When the luminous ring 2 emits green light, the door can be opened; when the luminous ring 2 emits red light, opening the door can be delayed. In other embodiments, the control system can control the illumination mode of the luminous ring 2. For example, if the external conditions are safe, the control system can control the luminous ring 2 to remain constantly lit; if the external conditions are dangerous, the control system can control the luminous ring 2 to flash. This allows passengers to understand the external situation based on the illumination mode of the luminous ring 2. When the luminous ring 2 is constantly lit, the door can be opened; when the luminous ring 2 flashes, opening the door can be delayed. Furthermore, the number of luminous rings 2 can be one, two, or more, depending on the size and specifications of the handrail body 1 and the passenger's usage habits. This embodiment does not limit this.

[0047] It should be noted that the warnings given about external conditions in this embodiment of the invention include both warnings given when there is danger outside the vehicle and warnings given when there is no danger outside the vehicle. For example, if a non-motorized vehicle passes by outside the vehicle, the light-emitting ring 2 can emit red light to warn the passenger that there is danger outside the vehicle and that the passenger should be careful when opening the door; if there is neither a vehicle passing by nor an obstacle outside the vehicle, the light-emitting ring 2 can emit green light to warn the passenger that it is safe outside the vehicle and that the passenger can open the door.

[0048] In summary, the handrail of this embodiment includes a handrail body 1 and a light-emitting ring 2. The handrail body 1 is fixedly connected to the B-pillar of the vehicle. The light-emitting ring 2 is sleeved on the handrail body 1 and fixedly connected to it. The light-emitting ring 2 is electrically connected to the vehicle's control system. The control system can control the light-emitting ring 2 to emit indicator light, allowing passengers to promptly understand the external conditions and decide whether to open the door. Compared to the prior art, the handrail of this embodiment, in addition to providing support for passengers getting on and off the vehicle, also provides a function of alerting passengers to external conditions, thus enriching the handrail's functionality, improving its effective utilization rate, and eliminating the need for in-vehicle alerts, thereby controlling the overall cost of vehicle components and improving the effective utilization of interior space.

[0049] Optionally, Figure 2 An exploded schematic diagram of a handrail according to an embodiment of the present invention is shown, with reference to... Figure 1 and Figure 2The handrail body 1 includes a main body segment 11, a first connecting segment 12, and a second connecting segment 13; the first connecting segment 12 and the second connecting segment 13 are disposed on both sides of the main body segment 11 and are detachably connected to the main body segment 11; the first connecting segment 12 and the second connecting segment 13 are used for fixed connection with the B-pillar; the light-emitting ring 2 is sleeved on any one of the main body segment 11, the first connecting segment 12, and the second connecting segment 13.

[0050] In this embodiment, the handrail body 1 is a segmented, detachable structure, including a main body segment 11, a first connecting segment 12, and a second connecting segment 13. The main body segment 11 has a columnar structure, which can be any columnar structure such as cylindrical, square, or prismatic; this embodiment does not limit this. The main body segment 11 is mainly used for passengers to grip, so the surface of the main body segment can be made rough, or an anti-slip structure can be provided on the surface of the main body segment to increase friction and prevent the hand from slipping. The first connecting segment 12 and the second connecting segment 13 are located on both sides of the main body segment 11 along its extension direction. The first connecting segment 12 and the second connecting segment 13 are detachably connected to the main body segment 11, and the detachable connection methods include, but are not limited to, screw connection and snap-fit ​​connection. During the installation of the handrail, the first connecting segment 12 and the second connecting segment 13 are first detachably connected to the main body segment 11 to form a complete handrail. Then, the ends of the first connecting segment 12 and the second connecting segment 13 furthest from the main body segment 11 are fixedly connected to the vehicle's B-pillar. The connection method includes, but is not limited to, assembly connection and welding, ensuring the reliability of the connection between the first connecting segment 12 and the second connecting segment 13 and the B-pillar. The luminous ring 2 can be fitted onto the main body segment 11, the first connecting segment 12, or the second connecting segment 13. Figure 1 and Figure 2 The diagram shows the arrangement of the luminous ring 2 on the first connecting segment 12, with the luminous ring 2 positioned at the end of the first connecting segment 12 near the main body segment 11 to facilitate installation and removal of the luminous ring 2. Of course, in practical applications, the placement of the luminous ring 2 can be adjusted according to passenger habits and preferences, and this embodiment does not impose any limitations on this.

[0051] In this embodiment, the handrail is designed as a segmented, detachable structure, which greatly facilitates the disassembly and maintenance of the handrail. The light-emitting ring 2 can be installed on the main body segment 11, or on the first connecting segment 12 or the second connecting segment 13. Of course, if there are many light-emitting rings 2, they can be installed on the main body segment 11, the first connecting segment 12 or the second connecting segment 13. This embodiment does not limit this.

[0052] Optionally, the first connecting segment 12 and / or the second connecting segment 13 are provided with mounting grooves, and the light-emitting ring 2 is embedded and fixed in the mounting grooves.

[0053] In this embodiment, if there is only one light-emitting ring 2, the mounting groove can be provided on the first connecting segment 12 or the second connecting segment 13. If there are two light-emitting rings 2, the mounting grooves can be provided on the first connecting segment 12 and the second connecting segment 13 respectively. If there are multiple light-emitting rings 2, one or more mounting grooves can be provided on the first connecting segment 12 and the second connecting segment 13 respectively. By providing the mounting groove on the first connecting segment 12 and / or the second connecting segment 13, the light-emitting ring 2 is embedded and fixed in the mounting groove, also located on the first connecting segment 12 and / or the second connecting segment 13. This allows the light-emitting ring 2 to avoid being repeatedly touched by passengers, preventing contamination of the surface of the light-emitting ring 2, thereby improving the luminous effect of the light-emitting ring 2. In addition, the mounting groove can effectively limit the position of the light-emitting ring 2, and the light-emitting ring 2 can be fixedly connected to the mounting groove by means of snap-fit, adhesive connection, etc., thereby effectively improving the connection reliability between the light-emitting ring 2 and the handrail body 1.

[0054] Optionally, the mounting groove is located at the end of the first connecting segment 12 near the main body, and / or the mounting groove is located at the end of the second connecting segment 13 near the main body.

[0055] In this embodiment, when the mounting groove is located in the first connecting section 12, it is further located at the end of the first connecting section 12 near the main body. When the mounting groove is located in the second connecting section 13, it is further located at the end of the second connecting section 13 near the main body. With this arrangement, if the light-emitting ring 2 malfunctions, the handrail body 1 can be disassembled, and the first connecting section 12 or the second connecting section 13 can be separated from the main body section 11. After separation, the light-emitting ring 2 can be directly removed from the end of the first connecting section 12 or the second connecting section 13, which greatly facilitates the inspection and maintenance of the light-emitting ring 2.

[0056] Optionally, refer to Figure 2 The main body segment 11 is provided with a first elastic fastening part 14 at the end near the first connecting segment 12, or the first connecting segment 12 is provided with a first elastic fastening part 14 at the end near the main body segment 11; the main body segment 11 and the first connecting segment 12 are fastened together by the first elastic fastening part 14.

[0057] In this embodiment, the main body segment 11 and the first connecting segment 12 are connected by an elastic fastening method. The first elastic fastening part 14 can be provided at the end of the main body segment 11 near the first connecting segment 12, or at the end of the first connecting segment 12 near the main body segment 11. The first elastic fastening part 14 can be an elastic protrusion with elastic deformation function. If the first elastic fastening part 14 is provided at the main body segment 11, the end of the first connecting segment 12 near the main body segment 11 is provided with a fastening groove that cooperates with the elastic fastening part. If the first elastic fastening part 14 is provided at the first connecting segment 12, the end of the main body segment 11 near the first connecting segment 12 is provided with a fastening groove that cooperates with the elastic fastening part. The first elastic fastening part 14 is embedded in the fastening groove, thereby realizing the fastening connection between the main body segment 11 and the first connecting segment 12. The connection structure is simple and helps to reduce the processing and assembly difficulty of the handrail body 1.

[0058] Optionally, refer to Figure 2 The main body segment 11 is provided with a second elastic fastening part 15 at the end near the second connecting segment 13, or the second connecting segment 13 is provided with a second elastic fastening part 15 at the end near the main body segment 11; the main body segment 11 and the second connecting segment 13 are fastened together by the second elastic fastening part 15.

[0059] In this embodiment, the main body segment 11 and the second connecting segment 13 are also connected by elastic fastening. The second elastic fastening part 15 can be provided at the end of the main body segment 11 near the second connecting segment 13, or at the end of the second connecting segment 13 near the main body segment 11. Similarly, the second elastic fastening part 15 can also be an elastic protrusion with elastic deformation function. If the second elastic fastening part 15 is provided at the main body segment 11, the end of the second connecting segment 13 near the main body segment 11 is provided with a fastening groove that cooperates with the elastic fastening part. If the second elastic fastening part 15 is provided at the second connecting segment 13, the end of the main body segment 11 near the second connecting segment 13 is provided with a fastening groove that cooperates with the elastic fastening part. The second elastic fastening part 15 is embedded in the fastening groove, thereby realizing the fastening connection between the main body segment 11 and the second connecting segment 13.

[0060] In this embodiment, the connection between the main body segment 11 and the first connecting segment 12 and the second connecting segment 13 is achieved by elastic fastening. During the assembly and disassembly process, the first elastic fastening part 14 and the second elastic fastening part 15 can be squeezed and deformed, thereby allowing the main body segment 11 to have a relatively large amount of movement, which makes it easier to assemble and disassemble the main body segment 11 with the first connecting segment 12 and the second connecting segment 13.

[0061] Optionally, Figure 3 A schematic diagram of a lighting component according to an embodiment of the present invention is shown, with reference to... Figure 3 The handrail also includes a lighting component 3, which is located on the main body section 11.

[0062] In this embodiment, the lighting component 3 is located on the main body section 11. When the main body section 11 is detached from the first connecting section 12 and the second connecting section 13, the lighting component 3 in the main body section 11 can provide illumination, thereby further enriching the function of the handrail. If the vehicle enters a dark environment, passengers can remove the handrail and use the lighting component 3 of the main body section 11 for illumination, so that passengers can find personal items or explore the surrounding environment, and can also use the lighting component 3 to check the vehicle situation.

[0063] Optionally, the main body segment 11 has a mounting cavity at the end near the first connecting segment 12 and / or the second connecting segment 13, and the lighting component 3 is embedded and fixed in the mounting cavity.

[0073] Figure 5 A flowchart of a vehicle warning method according to an embodiment of the present invention is shown, with reference to... Figure 5 The vehicle warning method of this invention includes:

[0074] Step 101: Obtain the vehicle's speed.

[0075] In this step, the vehicle's control system acquires the vehicle's speed. The control system has been described in the previous embodiments and will not be repeated here.

[0076] Step 102: If the vehicle speed meets the first preset condition, determine the target door.

[0077] In this step, the first preset condition can be set as the vehicle's speed being 0. When the vehicle's speed is 0, the control system determines that the vehicle is in a parked state. At this time, passengers may open the door to get off the vehicle, so it is necessary to determine the target door, which is the door where the passenger gets off.

[0078] Step 103: Obtain the working condition information of the outside of the target door.

[0079] In this step, the operating condition information outside the target door includes driving condition information and environmental condition information. Driving condition information refers to the travel and distance information of dynamic obstacles such as motor vehicles and non-motor vehicles, while environmental condition information refers to the distance information of static obstacles such as streetlights, signs, and buildings. After identifying the target door, the control system can acquire the operating condition information outside the target door.

[0080] Step 104: Control the light-emitting ring on the handrail to emit indicator light according to the working condition information.

[0081] In this step, the operating condition information includes both hazardous and safe operating conditions. Specifically, when the area outside the target door is in a hazardous condition, the indicator light on the handrail can be activated; conversely, when the area outside the target door is in a safe condition, the indicator light on the handrail can also be activated. For example, if a non-motorized vehicle is passing by outside the vehicle, the indicator light can emit a red light to warn passengers of the danger outside the door and to proceed with caution when opening the door; if there are no vehicles or obstacles outside the vehicle, the indicator light can emit a green light to warn passengers that the area outside the door is safe and that they can open the door.

[0082] The term "dangerous operating condition" refers to situations where dynamic obstacles such as motor vehicles or non-motor vehicles are traveling too fast or are too close to the target vehicle door, or where static obstacles such as streetlights, signs, or buildings are too close to the target vehicle door. The term "safe operating condition" refers to situations where there are no dynamic obstacles such as motor vehicles or non-motor vehicles outside the target vehicle door, or where dynamic obstacles are too far from the target vehicle door, or where static obstacles such as streetlights, signs, or buildings are too far from the target vehicle door. In some embodiments, when the driving condition is considered dangerous, the control system may control the illuminated ring on the handrail to emit indicator light. The indicator light may indicate the color or the mode of illumination of the illuminated ring; the method described in this step is not limited in this respect.

[0083] Figure 6 A flowchart of another vehicle warning method according to an embodiment of the present invention is shown, with reference to Figure 6 The method includes:

[0084] Step 201: Obtain the vehicle's speed.

[0085] This step is the same as the implementation method described in step 101 above, and will not be repeated here.

[0086] Step 202: When the vehicle speed meets the first preset condition, obtain the pressure of the seat inside the vehicle.

[0087] In this step, the first preset condition can be set to a vehicle speed of 0. When the vehicle speed is 0, the control system acquires the pressure of each seat in the vehicle. Pressure sensors can be installed on each seat to detect the seat pressure and feed it back to the control system.

[0088] Step 203: If the pressure meets the second preset condition, determine the target seat.

[0089] In this step, the pressure sensor detects a higher pressure value when the passenger is seated, and a lower pressure value when the passenger gets up. The second preset condition can be set to a pressure sensor value that is less than a preset value. This preset value can be set according to the passenger's actual needs, and this method is not limited in this step. The control system can determine whether the pressure of each seat meets the second preset condition. If the seat pressure meets the second preset condition, then that seat is designated as the target seat. It should be noted that the number of passengers may be large, therefore the number of target seats is not limited to one.

[0090] Step 204: Obtain the distance between the passenger in the target seat and the car door.

[0091] In this step, since the number of target seats is not limited to one, the number of target doors is also not limited to one. After the target seat is determined, the in-vehicle camera can capture the distance between the passenger and the door and feed it back to the control system, which can then analyze and compare the acquired distances.

[0092] Step 205: If the distance meets the third preset condition, determine the car door as the target car door.

[0093] In this step, the third preset condition can be set as the distance value captured by the in-vehicle camera being less than a preset value. This preset value can be set according to the passenger's actual needs, and the method used in this step is not limited in this regard. When the in-vehicle camera detects that the distance between the passenger and the door is less than the preset value, the control system determines that the passenger in the seat is about to disembark from that door, thus identifying that door as the target door. Alternatively, the door closest to the target seat can also be directly identified as the target door.

[0094] Step 206: Detect whether there are obstacles outside the target door.

[0095] In this step, devices such as radar or cameras installed outside the vehicle can be used to detect whether there are obstacles outside the target vehicle door. These obstacles include dynamic obstacles such as motor vehicles and non-motor vehicles, as well as static obstacles such as streetlights, signs, and buildings.

[0096] Step 207: If there is an obstacle outside the target door, obtain the distance between the target door and the obstacle.

[0097] In this step, if external radar or cameras detect an obstacle outside the car door, they can continue to use these devices to determine the distance between the target car door and the obstacle. The radar measures the time it takes for a radar signal, which travels at the speed of light, to reach the obstacle and return, thus determining the distance between the target car door and the obstacle. While cameras typically do not directly measure the distance between an object and the camera, specific techniques or methods, such as binocular vision, can indirectly estimate the distance between the obstacle and the camera.

[0098] Step 208: If the distance meets the fourth preset condition, determine that the working condition information is a dangerous working condition.

[0099] In this step, the fourth preset condition can be set as the distance between the target door and the obstacle being less than a preset value. This preset value can be set to 1m, 2m, or 3m, etc., and is not limited in this embodiment. When the distance between the target door and the obstacle is less than the preset value, it may be dangerous for a passenger to open the door; therefore, the external working conditions at this time are determined to be a dangerous situation.

[0100] Step 209: When the working condition information indicates a dangerous working condition, control the light-emitting ring on the handrail to emit indicator light.

[0101] This step is the same as the implementation method described in step 104 above, and will not be repeated here.

[0102] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.

[0103] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
