[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0030] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more.

[0031] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0032] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0033] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0034] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0035] When the vehicle is turning, the taillights on the corresponding side will flash to inform the vehicle behind it of its turning intention. When temporarily stopping, the taillights of the vehicle will flash at the same time to serve as a warning.

[0036] The taillights generally consist of two parts: the first part is fixed to the rear of the car body, and the second part is installed on the trunk lid, which moves with the opening and closing of the trunk lid.

[0037] However, in actual use, if the trunk lid is opened, the second part of the taillight may move as the trunk lid rises, resulting in a reduction in the visible area of ​​the turn signal, thereby affecting its warning effect.

[0038] In response to the above problems, an embodiment of the present application provides a rear taillight and a vehicle. By adding a lamp body to the rear taillight, the newly added lamp body can be revealed when the tailgate is opened. The newly added lamp body and the first lamp body located on the rear panel of the vehicle together indicate the movement state of the vehicle, thereby increasing the visible area of ​​the rear taillight and improving the safety of the vehicle.

[0039] The following will refer to Figures 1 to 6 The rear taillight and vehicle provided in the embodiments of the present application are described.

[0040] It should be noted that the rear taillight in the present application may be a rear turn signal lamp, and the present embodiment takes the rear turn signal lamp as an example to introduce the structure and use of the rear taillight. In addition to the rear turn signal lamp, the rear taillight may also include one or more of a rear fog lamp, a brake lamp, a reverse lamp, and a rear width indicator lamp.

[0041] It should also be noted that the use scenarios of the taillights in this application include but are not limited to vehicles, and can also be set on other movable equipment, such as aircraft, large mechanical equipment, etc.

[0042] In addition, the vehicle in this application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the car model, the car in this application may be a sedan model, an off-road model, a multi-purpose vehicle (MPV) model or other models. Generally, a vehicle is provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.

[0043] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.

[0044] On this basis, refer to Figures 1 to 3 An embodiment of the present application provides a rear taillight 100 for indicating the movement state of the vehicle 200 to the rear side of the vehicle 200 .

[0045] Specifically, the rear tail lamp 100 includes a first lamp body 110 , a second lamp body 120 and a third lamp body 130 .

[0046] Among them, the first lamp body 110 is arranged at the rear of the vehicle 200 and is located on the side of the tailgate 212 of the vehicle 200; the second lamp body 120 is arranged at the tailgate 212, and is used to indicate the movement state of the vehicle 200 together with the first lamp body 110 when the tailgate 212 is closed; the third lamp body 130 is arranged at the rear of the vehicle 200, and is used to indicate the movement state of the vehicle 200 together with the first lamp body 110 when the tailgate 212 is opened.

[0047] The rear taillight provided in the embodiment of the present application is provided with a third lamp body 130 on the basis of the traditional rear taillight structure, and the third lamp body 130 can be revealed when the back door 212 is in the open state. When the back door 212 of the vehicle 200 is in the closed state, the first lamp body 110 and the second lamp body 120 jointly indicate the movement state of the vehicle. When the back door 212 of the vehicle 200 is in the open state, the first lamp body 110 and the third lamp body 130 jointly indicate the movement state of the vehicle 200, so that when the vehicle 200 is turned on, the rear taillight 100 can also ensure a sufficiently large indication area, so that the rear taillight has higher visibility, and then it is easier for the vehicles or pedestrians behind to see the state changes of the vehicle, so as to improve the safety of the vehicle.

[0048] It should be noted that the above-mentioned "indication of vehicle movement status" includes the temporary parking status, left turn status and right turn status of the vehicle. When the vehicle is in a temporary parking status, the driver generally reminds and warns vehicles and pedestrians by flashing the two rear tail lights on the rear side of the vehicle at the same time, that is, by "double flashing". For example, if a vehicle temporarily stops on a highway due to a malfunction, if the rear door of the vehicle needs to be opened at this time, the first lamp body 110 and the third lamp body 130 can jointly indicate the braking status of the vehicle; if the rear door does not need to be opened, the first lamp body 110 and the second lamp body 120 can jointly indicate the braking status of the vehicle. When the vehicle is about to turn left, the turning status can be indicated by the flashing state of the left turn signal. When the vehicle is about to turn right, the turning status can be indicated by the flashing state of the right turn signal.

[0049] In addition, in the embodiment of the present application, the shape of the rear taillight is not limited, and the shape of the rear taillight can be set according to the overall appearance requirements of the vehicle as long as it can meet the visibility requirements.

[0050] In a possible implementation of the present application, referring to Figure 3 , a minimum distance L1 between an apparent surface of the first lamp body 110 and an apparent surface of the third lamp body 130 is less than 75 mm.

[0051] With such arrangement, when the tailgate is opened, the first lamp body 110 and the third lamp body 130 can cooperate to generate a common indication signal. In addition, the distance between the visual surfaces of the two is closer, so that the rear taillight has a larger visual surface area, increasing the visibility of the rear taillight and thus improving the safety of the vehicle.

[0052] It should be noted that the above-mentioned "apparent surface" refers to: according to the manufacturer's requirements, or the vertical projection of the boundary of the luminous surface projected on the outer surface of the light distribution lens on a plane in a specific observation direction. The plane is perpendicular to the observation direction and contacts the outermost point of the light distribution lens.

[0053] Further, the minimum distance L1 between the visible surface of the first lamp body 110 and the visible surface of the third lamp body 130 is between 0 mm and 75 mm. For example, the value of L1 can be set to 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 70 mm, 75 mm or any value between 0 mm and 75 mm according to actual needs.

[0054] Accordingly, in a possible implementation of the present application, the minimum distance between the visual surface of the first lamp body 110 and the visual surface of the second lamp body 120 is also less than 75 mm. This arrangement allows the first lamp body 110 and the second lamp body 120 to work together to generate a common indication signal when the back door 212 is closed. In addition, the distance between the visual surfaces of the two is relatively close, so that the rear taillight has a larger visual surface area, which increases the visibility of the rear taillight and further improves the safety of the vehicle.

[0055] In a possible implementation of this application, please refer to Figure 3 The visual surface of the first lamp body 110 and the visual surface of the third lamp body 130 form a first visual surface of the rear tail lamp 100, and a geometric visible angle β of the first visual surface in the horizontal direction is greater than 125°.

[0056] Such an arrangement enables, when the first lamp body 110 and the third lamp body 130 jointly indicate the movement state of the vehicle, to have a larger viewing angle, thereby facilitating pedestrians and vehicles behind the vehicle to observe the vehicle's indication signal, thereby improving the safety of the vehicle.

[0057] It should be noted that the above-mentioned "geometric visible angle" refers to: the minimum solid angle at which the visual surface of the lamp body is visible. The solid angle is determined by a part of a sphere, and the center of the sphere is located at the center point of the first visual surface.

[0058] Specifically, in a possible implementation of this application, please continue to refer to Figure 3 , taking the vertical plane where the center point of the first visual surface is located as the first reference plane 101, the geometric visible angle β of the first visual surface in the horizontal direction includes a first horizontal angle β1 located inside the first reference plane 101, and the angle of the first horizontal angle β1 is greater than 45°. Such a setting can make it easier for pedestrians and vehicles inside the vehicle 200 to observe the flashing of the rearview lamp.

[0059] Exemplarily, the value of the first horizontal angle β1 may be 45°, 50°, 55°, 60° or 70°.

[0060] It should be noted that the above-mentioned "first reference plane" refers to a vertical plane perpendicular to the ground, and this vertical plane is the plane where the center point of the first visual surface is located. The above-mentioned "inside of the first reference plane" refers to the side of the first reference plane close to the center line of the vehicle.

[0061] Accordingly, with the vertical plane where the center point of the first visual surface is located as the first reference plane 101, the geometric visible angle β of the first visual surface in the horizontal direction includes a second horizontal angle β2 located outside the first reference plane 101, and the angle of the second horizontal angle β2 is greater than 80°. This arrangement enables pedestrians and vehicles outside the vehicle 200 to more easily observe the flashing of the rearview lamp.

[0062] Exemplarily, the second horizontal angle β2 may be 80°, 85°, 90°, 95°, or 100°.

[0063] It should be noted that the above-mentioned “outer side of the first reference plane” refers to the side of the first reference plane away from the center line of the vehicle.

[0064] In a possible implementation of the present application, referring to Figure 4 The visual surface of the first lamp body 110 and the visual surface of the third lamp body 130 form a first visual surface of the rear tail lamp 100, and a geometric visible angle α of the first visual surface in the vertical direction is greater than 30°.

[0065] Such an arrangement enables pedestrians or other vehicles to more easily observe the indication of the rear taillight when they are at a position lower than or higher than the vehicle 200, further improving the safety of the vehicle. For example, when the vehicle 200 is at a high position on an uphill slope, vehicles at a low position can more easily observe the flashing state of the rear taillight. For another example, when the vehicle 200 is at a low position on a downhill slope, vehicles at a high position can also more easily observe the flashing state of the taillight.

[0066] Specifically, the horizontal plane where the center point of the first visual surface is located is taken as the second reference plane 102, and the geometric visible angle α of the first visual surface in the vertical direction includes a first vertical angle α1 located on the upper side of the second reference plane 102 and a second vertical angle α2 located on the lower side of the second reference plane 102, the first vertical angle α1 is greater than 15°, and the second vertical angle α2 is greater than 15°.

[0067] It should be noted that the above-mentioned “second reference plane” refers to a horizontal plane parallel to the ground, and this horizontal plane is the plane where the center point of the first visual surface is located.

[0068] For example, the first vertical angle α1 may have a value of 15°, 25°, 30°, 35°, or 45°. The second vertical angle α2 may have a value of 15°, 25°, 30°, 35°, or 45°.

[0069] It should be noted that the values ​​of the first vertical angle α1 and the second vertical angle α2 may be the same or different, as long as they meet the actual visibility requirements.

[0070] In a possible implementation of this application, please refer to Figure 5 As shown, the third lamp body 130 includes: a housing 131 , a light emitting portion 132 and a light distribution lens 133 .

[0071] Specifically, there is a accommodating space in the shell 131, and the shell 131 includes a fixing part 1311 and a light-transmitting part 1312, the fixing part is used to connect with the vehicle 200, and the light-transmitting part is used to transmit light; the light-emitting part 132 is arranged in the accommodating space, and is used to generate light; the light distribution mirror 133 is arranged in the accommodating space and is located between the light-emitting part 132 and the light-transmitting part, and is used to change the path of the light so that the light has a more uniform and bright effect.

[0072] It should be noted that the fixing portion 1311 may be a snap-fit ​​structure or a fastener such as a screw or a nut, and it only needs to achieve the fixing effect between the shell 131 and the vehicle body, and the specific structure is not limited in this embodiment.

[0073] It should also be noted that the structures of the first lamp body 110 and the second lamp body 120 may be the same as or different from the third lamp body 130 , which is not limited in this embodiment.

[0074] In a second aspect, the present application embodiment further provides a vehicle 200, please refer to Figures 1 to 6 The vehicle 200 includes a vehicle body 210, a first rear taillight and a second rear taillight. The first rear taillight and the second rear taillight are disposed at the rear of the vehicle body 210 and are located at two opposite sides of the rear of the vehicle body 210. The first rear taillight and the second rear taillight are both the above-mentioned rear taillights 100.

[0075] In the above structure, the first rear taillight and the second rear taillight each include a first lamp body 110, a second lamp body 120 and a third lamp body 130. For example, the first rear taillight may be a left turn signal, and the second rear taillight may be a right turn signal. Since the rear taillight 100 has the advantages of a larger visible area and higher safety, a vehicle having the same also has the advantage of higher safety.

[0076] Specifically, in a possible implementation of the present application, please refer to Figures 1 to 6 The vehicle body 210 includes a rear panel 211 and a rear door 212. The rear panel 211 has a trunk opening. The rear door 212 is disposed on the rear panel 211 and has a closed position for shielding the trunk opening and an open position for opening the trunk opening.

[0077] The first lamp body 110 of the first rear tail lamp is disposed on the rear plate 211 and located at the side of the rear door 212, the second lamp body 120 is disposed on the rear door 212 and is disposed close to the first lamp body 110, and the third lamp body 130 is disposed on the rear plate 211 and is disposed close to the trunk opening. When the rear door 212 is in a closed position, the rear door 212 shields the third lamp body 130, and the first lamp body 110 and the second lamp body 120 jointly indicate the motion state of the vehicle 200; when the rear door 212 is in an open position, the third lamp body 130 is exposed from the rear door 212, and the first lamp body 110 and the third lamp body 130 jointly indicate the motion state of the vehicle 200.

[0078] The vehicle provided in the embodiment of the present application has a body 210 of the vehicle including a back plate 211 and a back door 212, and the back door is used to open or close the trunk. When the back door 212 is in an open state, the second lamp body 120 rises with the back door 212, and the visibility is insufficient, but the third lamp body 130 is exposed due to the opening of the back door 212, and the third lamp body 130 can be used together with the first lamp body 110 to indicate the existence or movement state of the vehicle 200. When the back door is in a closed state, the third lamp body 130 is blocked, and the first lamp body 110 and the second lamp body 120 can be used together to indicate the existence or movement state of the vehicle 200. The structure of the above-mentioned vehicle realizes that no matter whether the back door 212 is in an open state or a closed state, the taillights can have a large enough visible area to transmit the signal sent by the vehicle, thereby ensuring the visibility of the taillights under various road conditions and increasing the safety of vehicle driving.

[0079] It should be noted that the second rear tail light and the first rear tail light may be symmetrically arranged about the center line of the vehicle 200 .
