AI Technical Summary
In existing double-door vehicles, there are two problems with the arrangement of rear speakers on the rear door: one is that they are easily blocked by the rear seats, resulting in poor sound effects; the other is that the rotational torque is large when switching the rear door, resulting in a greater impact.
A rear door assembly is designed, in which the speaker body is located on the side of the pronunciation mesh cover close to the rear hinge, and the sound guide tube transmits the sound waves emitted by the speaker body to the pronunciation mesh cover, thereby reducing the rotational torque when switching the rear door and improving the sound effect.
By bringing the speaker body closer to the rear hinge, the rotational torque when switching the rear door is reduced, the impact on the rear door is reduced, and the sound effect is improved, avoiding the problem of rear seat obstruction.

Description
Technical Field
[0001] This application relates to the technical field of vehicles, and particularly to a pair - opening vehicle and its rear door assembly. Background Art
[0002] With the economic development, consumption upgrading, and the wide popularity of high - end vehicles, pair - opening doors are increasingly becoming the mainstream design of high - end vehicles. Referring to Figure 1 and Figure 2 , a general pair - opening vehicle includes a vehicle body 10, a front row seat 21, a rear row seat 22, a front door 31, and a rear door 41, etc. The front door 31 is hinged to the vehicle body 10 through a front hinge 32. The rear door 41 is hinged to the vehicle body 10 through a rear hinge 42. A front speaker 33 is provided on the front door 31. A rear speaker 43 is provided on the rear door 41.
[0003] Currently, in pair - opening vehicles, there are usually two arrangements for the rear speaker 43 on the rear door 41. As Figure 1 shown, the first arrangement is to place the rear speaker 43 at one end of the rear door 41 close to the rear hinge 42. However, this causes the rear speaker 43 to be easily blocked by the rear row seat 22, resulting in a rear - shifted sound image and poor sound effects. As Figure 2 shown, the second arrangement is to place the rear speaker 43 at one end of the rear door 41 far from the rear hinge 42. However, this makes the rotational torque larger when opening and closing the rear door 41, thus causing a greater impact on the rear door 41. Utility Model Content
[0004] Based on this, in view of the above - mentioned technical problems existing in the two arrangements of the rear speaker on the rear door in the prior art, it is necessary to provide a pair - opening vehicle and its rear door assembly.
[0005] A rear door assembly, the rear door assembly includes a rear door and a speaker,
[0006] One end of the rear door is hinged to the vehicle body of the pair - opening vehicle through a rear hinge;
[0007] The speaker is arranged on the rear door; the speaker includes a speaker body, a sound guide tube, and a sounding grille; one end of the sound guide tube is connected to the speaker body, the sounding grille is connected to the other end of the sound guide tube and covers the orifice of the sound guide tube, and the sound guide tube is used to conduct the sound wave emitted by the speaker body to the sounding grille; the speaker body is located on the side of the sounding grille close to the rear hinge.
[0008] In one embodiment, the speaker body is located at one end of the rear door close to the rear hinge, and the sounding grille is located at one end of the rear door far from the rear hinge.
[0009] The extending direction of the sound guide tube is perpendicular to the vertical direction and the thickness direction of the rear door.
[0010] In one embodiment, the loudspeaker body includes a housing and a diaphragm assembly located inside the housing, and a first sound outlet hole is provided on the housing; one end of the sound guide tube is communicated with the first sound outlet hole.
[0011] In one embodiment, a front cavity and a rear cavity are formed inside the housing, the front cavity and the rear cavity are respectively located on both sides of the diaphragm assembly, one side of the diaphragm assembly having a sound hole faces the front cavity, and the first sound outlet hole is provided on the cavity wall of the front cavity.
[0012] In one embodiment, the loudspeaker further includes a phase inverter tube, a second sound outlet hole is provided on the cavity wall of the rear cavity, one end of the phase inverter tube is communicated with the second sound outlet hole, and the other end of the phase inverter tube is communicated with the sound guide tube; the phase inverter tube is used for inverting the sound wave in the rear cavity and outputting it into the sound guide tube.
[0013] In one embodiment, a first sound through hole is provided on the side wall of the sound guide tube, and the end of the phase inverter tube far from the second sound outlet hole is communicated with the first sound through hole.
[0014] In one embodiment, the sound guide tube and the phase inverter tube are arranged in parallel.
[0015] In one embodiment, the sounding grille is installed on the interior trim panel of the rear door.
[0016] In one embodiment, the loudspeaker is a reverse magnetic circuit loudspeaker.
[0017] A double-leaf door vehicle includes the rear door assembly according to any one of the above embodiments.
[0018] In the above double-leaf door and its rear door assembly, the loudspeaker body is used to emit sound waves. Since one end of the sound guide tube is connected to the loudspeaker body, the sounding grille is connected to the other end of the sound guide tube and covers the tube orifice of the sound guide tube. Therefore, the sound guide tube can conduct the sound waves emitted by the loudspeaker body to the sounding grille, and then the sound waves are transmitted to the outside through the sounding grille, so that the passengers in the vehicle can receive the sound waves. By respectively arranging the loudspeaker body and the sounding grille at both ends of the sound guide tube, the loudspeaker body is located on the side of the sounding grille close to the rear hinge, so that the relatively heavy (compared with the sounding grille) loudspeaker body can be as close as possible to the rear hinge, while the sounding grille is relatively light, and thus the rotational torque when opening and closing the rear door can be minimized, the impact on the rear door can be reduced, and the strength requirement for the rear door can be lowered. At the same time, the sounding grille (compared with the loudspeaker body) is far from the rear hinge. Therefore, the sound waves emitted through the sounding grille are not easily blocked by the rear seats, and thus the sound effect can be improved. Description of the Drawings

[0026] To make the above objects, features, and advantages of the present application more obvious and understandable, the following describes the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.
[0027] In the description of the present application, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.
[0028] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, if the term "a plurality" appears, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0029] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0030] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.
[0031] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it may be directly on the other element or there may also be an intermediate element. If an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.
[0032] Currently, in a pair of opening doors vehicle, there are usually two arrangements for the rear speaker 43 on the rear door 41. As Figure 1 shown, the first scheme is to arrange the rear speaker 43 at one end of the rear door 41 close to the rear hinge 42. However, this will cause the rear speaker 43 to be easily blocked by the rear seat 22, the sound image is backward, and the sound effect is not good. As Figure 2As shown, the second solution is to arrange the rear speaker 43 at one end of the rear door 41 away from the rear hinge 42. However, this will result in a relatively large rotational torque when the rear door 41 is opened or closed, thus causing a greater impact on the rear door 41. In view of this, an embodiment of the present application provides a rear door assembly. By respectively arranging the speaker body 210 and the sound emitting grille 230 at both ends of the sound guiding tube 220, the speaker body 210 is located on the side of the sound emitting grille 230 close to the rear hinge 42, so that the relatively heavy speaker body 210 (relative to the sound emitting grille 230) can be as close as possible to the rear hinge 42, while the sound emitting grille 230 is lighter in weight, thereby being able to minimize the rotational torque when the rear door 41 is opened or closed and reduce the impact on the rear door 41. At the same time, the sound emitting grille 230 (relative to the speaker body 210) is farther away from the rear hinge 42. Therefore, the sound waves emitted through the sound emitting grille 230 are not easily blocked by the rear row seat 22, and thus the sound effect can be improved.
[0033] Please refer to Figure 3 , a rear door assembly provided by an embodiment of the present application includes a rear door 41 and a speaker 200. One end of the rear door 41 is hinged to the vehicle body 10 of the double - leaf door vehicle through a rear hinge 42.
[0034] The speaker 200 is arranged on the rear door 41. The speaker 200 includes a speaker body 210, a sound guiding tube 220 and a sound emitting grille 230. One end of the sound guiding tube 220 is connected to the speaker body 210, and the sound emitting grille 230 is connected to the other end of the sound guiding tube 220 and covers the tube orifice of the sound guiding tube 220. The sound guiding tube 220 is used to conduct the sound waves emitted by the speaker body 210 to the sound emitting grille 230. The speaker body 210 is located on the side of the sound emitting grille 230 close to the rear hinge 42.
[0035] The above-mentioned backdoor component is applied to a double-leaf door vehicle, and the speaker body 210 is used to emit sound waves. Since one end of the sound guide tube 220 is connected to the speaker body 210, and the sound-emitting grille 230 is connected to the other end of the sound guide tube 220 and covers the nozzle of the sound guide tube 220, the sound guide tube 220 can conduct the sound waves emitted by the speaker body 210 to the sound-emitting grille 230, and then propagate to the outside through the sound-emitting grille 230, so that the passengers in the vehicle can receive the sound waves. By arranging the speaker body 210 and the sound-emitting grille 230 at both ends of the sound guide tube 220 respectively, the speaker body 210 is located on the side of the sound-emitting grille 230 close to the rear hinge 42, so that the relatively heavy (compared with the sound-emitting grille 230) speaker body 210 can be as close as possible to the rear hinge 42, while the weight of the sound-emitting grille 230 is lighter, thus the rotational torque when opening and closing the rear door 41 can be minimized, the impact on the rear door 41 can be reduced, and the strength requirement for the rear door 41 can be lowered. At the same time, the sound-emitting grille 230 is relatively far from the rear hinge 42 (compared with the speaker body 210). Therefore, the sound waves are not easily blocked by the rear seat 22 after being emitted from the sound-emitting grille 230, and the sound effect can be improved.
[0036] In addition, since the relatively heavy (compared with the sound-emitting grille 230) speaker body 210 can be as close as possible to the rear hinge 42, the torque caused by the gravity of the speaker body 210 can be minimized, and the strength requirement for the rear door 41 can be reduced; moreover, it is convenient to arrange the wire harness connected to the speaker body 210 and reduce the length of the wire harness.
[0037] Please refer to Figure 3 , in an embodiment, the extending direction of the sound guide tube 220 is perpendicular to the vertical direction and the thickness direction of the rear door 41. That is, the extending direction of the sound guide tube 220 is along the horizontal direction. The sound-emitting grille 230 and the speaker body 210 are respectively arranged at both ends of the sound guide tube 220, so that the sound-emitting grille 230 and the speaker body 210 can be distributed along the horizontal direction.
[0038] In other embodiments, the extending direction of the sound guide tube 220 is not limited to the above direction, and can also be inclined to the horizontal direction. Or, the sound guide tube has multiple pipe segments connected in sequence, and there can also be an inclined angle between adjacent pipe segments. As long as the sound-emitting grille 230 can be relatively far from the rear hinge 42 compared with the speaker body 210.
[0039] Please refer to Figure 3 , in an embodiment, the speaker body 210 is located at one end of the rear door 41 close to the rear hinge 42, and the sound-emitting grille 230 is located at one end of the rear door 41 far from the rear hinge 42.
[0040] In this embodiment, the speaker body 210 and the sounding grille 230 are respectively located at both ends of the rear door 41, so that the speaker body 210 can be closest to the rear hinge 42 to the greatest extent, and the sounding grille 230 can be farthest from the rear hinge 42 to the greatest extent.
[0041] Please refer to Figure 4 , in one embodiment, the speaker body 210 includes a housing 211 and a diaphragm assembly 212 located inside the housing 211. A first sound outlet hole 2111 is provided on the housing 211. One end of the sound guide tube 220 is communicated with the first sound outlet hole 2111.
[0042] The diaphragm assembly 212 is used to generate sound waves by vibrating. The sound waves propagate from the first sound outlet hole 2111 to the sound guide tube 220, and thus can be propagated to the sounding grille 230 through the sound guide tube 220.
[0043] The specific structure of the diaphragm assembly 212 can refer to the prior art and will not be elaborated here.
[0044] Please refer to Figure 4 , in one embodiment, the housing 211 has a front cavity 2112 and a rear cavity 2113. The front cavity 2112 and the rear cavity 2113 are respectively located on both sides of the diaphragm assembly 212. The side of the diaphragm assembly 212 with sound holes faces the front cavity 2112, and the first sound outlet hole 2111 is provided on the cavity wall of the front cavity 2112.
[0045] Specifically, a partition plate 2115 is provided inside the housing 211. The outer edge of the partition plate 2115 is connected to the inner wall of the housing 211. The diaphragm assembly 212 is installed on the partition plate 2115, so that the partition plate 2115 and the diaphragm assembly 212 divide the housing 211 into a front cavity 2112 and a rear cavity 2113.
[0046] Please refer to Figure 4 , in one embodiment, the speaker 200 further includes a phase inverter tube 213. A second sound outlet hole 2114 is provided on the cavity wall of the rear cavity 2113. One end of the phase inverter tube 213 is communicated with the second sound outlet hole 2114, and the other end of the phase inverter tube 213 is communicated with the sound guide tube 220. The phase inverter tube 213 is used to make the sound waves in the rear cavity 2113 out of phase and then output them into the sound guide tube 220.
[0047] When the diaphragm assembly 212 vibrates, the sound waves generated in the rear cavity 2113 are out of phase with those generated in the front cavity 2112. After the sound waves in the rear cavity 2113 enter the phase inverter tube 213, through the propagation in the phase inverter tube 213, the phase can be flipped by 180°, so that the sound waves in the rear cavity 2113 are out-of-phase output to the sound guide tube 220. The phase when the sound waves in the rear cavity 2113 are out-of-phase output is the same as that of the sound waves in the front cavity 2112. After the sound waves in the rear cavity 2113 are out-of-phase output to the sound guide tube 220, they can converge and superimpose with the sound waves from the front cavity 2112 with the same phase in the sound guide tube 220, so that the sound waves are based on the sense of strength and speed. The sound waves converged and superimposed in the sound guide tube 220 are transmitted to the sound-emitting mesh cover 230 and are emitted through the sound-emitting mesh cover 230 and then transmitted to the passengers in the vehicle.
[0048] Among them, the flipping of the sound wave phase by the phase inverter tube 213 can be achieved by adjusting the length of the phase inverter tube 213.
[0049] Please refer to Figure 4 , in an embodiment, a first sound passage port 221 is provided on the side wall of the sound guide tube 220, and one end of the phase inverter tube 213 away from the second sound outlet hole 2114 is communicated with the first sound passage port 221, so that the phase inverter tube 213 can be communicated with the sound guide tube 220.
[0050] Please refer to Figure 4 , in an embodiment, the sound guide tube 220 and the phase inverter tube 213 are arranged in parallel, and the structure is compact. It can be understood that the length of the phase inverter tube 213 is less than that of the sound guide tube 220.
[0051] Please refer to Figure 4 , in an embodiment, the sound guide tube 220 and the phase inverter tube 213 have a shared side wall. The end face of one end of the phase inverter tube 213 away from the second sound outlet hole 2114 is closed. The first sound passage port 221 is provided on the shared side wall, so that the sound guide tube 220 is communicated with the phase inverter tube 213.
[0052] Please refer to Figure 4 , in an embodiment, in some embodiments, the end face of one end of the phase inverter tube 213 away from the second sound outlet hole 2114 is closed. A second sound passage port 2131 is provided on the side surface of one end of the phase inverter tube 213 away from the second sound outlet hole 2114. The second sound passage port 2131 is communicated with the first sound passage port 221, so that the sound guide tube 220 is communicated with the phase inverter tube 213.
[0053] In an embodiment, the sound-emitting mesh cover 230 is installed on the interior trim panel of the rear door 41.
[0054] In an embodiment, the speaker 200 is a reverse magnetic circuit speaker, and its structure is thinner than that of a traditional speaker, which is beneficial to saving space and convenient for layout.
[0055] An embodiment of the present application provides a double-leaf door vehicle, including the rear door assembly of any one of the above embodiments.
[0056] In the above double-leaf door vehicle, the speaker body 210 is used to emit sound waves. Since one end of the sound guide tube 220 is connected to the speaker body 210, and the sound-emitting grille 230 is connected to the other end of the sound guide tube 220 and covers the pipe orifice of the sound guide tube 220, the sound guide tube 220 can conduct the sound waves emitted by the speaker body 210 to the sound-emitting grille 230, and then spread to the outside through the sound-emitting grille 230, so that the passengers in the vehicle can receive the sound waves. By respectively arranging the speaker body 210 and the sound-emitting grille 230 at both ends of the sound guide tube 220, the speaker body 210 is located on the side of the sound-emitting grille 230 close to the rear hinge 42, so that the relatively heavier (compared with the sound-emitting grille 230) speaker body 210 can be as close as possible to the rear hinge 42, while the weight of the sound-emitting grille 230 is lighter, and thus the rotational torque when opening and closing the rear door 41 can be minimized, the impact on the rear door 41 can be reduced, and the strength requirement for the rear door 41 can be reduced. At the same time, the sound-emitting grille 230 is relatively far from the rear hinge 42 (compared with the speaker body 210). Therefore, the sound waves are not easily blocked by the rear seat 22 after being emitted from the sound-emitting grille 230, and the sound effect can be improved.
[0057] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0058] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
