In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.
[0040] The present application provides a vehicle. As Figure 1 and Figure 2 shown, the vehicle includes a ceiling 2, a fixing member 1, and a microphone 3. For the sake of brevity of description, the thickness direction Z of the ceiling 2 is set as the reference direction herein. The ceiling 2 includes an assembly hole 21 extending along the thickness direction Z. The fixing member 1 passes through the assembly hole 21 and is connected to the microphone 3.
[0041] Combined with Figure 3 and Figure 4 , the fixing member 1 of the present application includes a mask portion 11 and a buckle portion 12. The mask portion 11 includes a mounting surface 111. The buckle portion 12 is disposed on the mounting surface 111 and extends along the thickness direction Z. The buckle portion 12 includes a fixing unit 121 and a bending unit 122. The fixing unit 121 is connected to the mounting surface 111 and encloses to form a fixing space 13 of the fixing member 1. The microphone 3 is fixed in the fixing space 13. The bending unit 122 includes a connection end 1221 and a free end 1222. The connection end 1221 is connected to the fixing unit 121.
[0042] Among them, the bending unit 122 can rotate around the connection end 1221 to switch the fixing member 1 between the initial state and the fixed state: when the fixing member 1 is in the initial state, the bending unit 122 extends along the thickness direction Z; when the fixing member 1 is in the fixed state, the extending direction of the bending unit 122 is different from the thickness direction Z.
[0043] When the fixing member 1 is assembled to the ceiling 2, it is inserted into the assembly hole 21 along the thickness direction Z in the initial state until the mounting surface 111 abuts against one side of the ceiling 2. Subsequently, the assembler rotates the bending unit 122 around the connection end 1221, thereby changing the extending direction of the bending unit 122. At this time, the fixing member 1 is in the fixed state and the bending unit 122 abuts against the other side of the ceiling 2. As Figure 2 shown, in Figure 2 the perspective view, since the extending direction of the bending unit 122 is different from the thickness direction Z at this time, it is difficult for the fixing member 1 to move downward out of the assembly hole 21 under the action of the bending unit 122. At this time, under the action of the bending unit 122 and the mounting surface 111, the fixing member 1 is clamped on the upper and lower sides of the ceiling 2.
[0044] One side of the ceiling 2 where the mask portion 11 is located should be understood as the side of the cockpit, while one side of the ceiling 2 where the bending unit 122 is located should be understood as the inner side of the vehicle assembly components.
[0045] The setting of the buckle portion 12 of the fixing member 1 of the present application can maintain the connection with the ceiling 2 when the vehicle collides, and prevent the fixing member 1 from detaching from the ceiling 2 towards the cockpit. In this way, the vehicle can improve safety to a certain extent and avoid secondary injuries to the occupants in the cockpit caused by the detachment of the fixing member 1. In addition, the fixing member 1 adopts a bendable bending unit 122, which is bent and fixed after passing through the assembly hole 21. This setting method is simpler and more efficient than the scheme of clamping the inner side of the ceiling 2 through a fixed buckle, and can also avoid damage to the ceiling 2 caused by violent assembly. Moreover, the fixing member 1 can be switched between the initial state and the fixed state without fixing the fixing member 1 through other bracket structures, which is beneficial to reducing the number of vehicle parts and the overall cost of the vehicle.
[0046] When the fixing member 1 is in the fixed state, the bending angle of the bending unit 122 can be maintained by the gravity of the microphone 3. As Figure 2 shown, the microphone 3 abuts against the side of the bending unit 122 away from the ceiling 2 in the thickness direction Z, so as to keep the bending unit 122 in contact with the ceiling 2.
[0047] The microphone 3 can be fixed in the fixing space 13 by being bonded to the fixing member 1. Alternatively, in some embodiments, the fixing member 1 further includes a fixing portion 14 provided on the mounting surface 111. The fixing portion 14 can be arranged in a manner adjacent to and connected to the fixing unit 121 as shown in Figure 3 and Figure 4 . The fixing portion 14 is provided with a clamping hole 141 communicating with the fixing space 13. In an embodiment where the microphone 3 is provided with a protruding structure, the protruding structure can be fixed in the fixing space 13 by being clamped in the clamping hole 141. In other words, in this embodiment, the microphone 3 and the fixing member 1 are detachably connected. This way, when the vehicle generates an excessive collision force, the microphone 3 can directly separate from the fixing member 1, preventing the fixing member 1 and the microphone 3 from hitting the occupants in the cockpit as a whole, which is beneficial to further improving the safety performance of the vehicle.
[0048] The retention of the bending angle of the bending unit 122 can also be achieved in other ways. In an alternative embodiment, the buckle portion 12 includes a clamping unit 123 provided at one end of the fixing unit 121 away from the mounting surface 111. The extending direction of the clamping unit 123 is different from the thickness direction Z. The bending unit 122 includes a clamping surface 1223 and an avoidance space 1224 provided at the connecting end 1221. The avoidance space 1224 is used to avoid the clamping unit 123 when the bending unit 122 rotates. As shown in Figure 4 , when the fixing member 1 is in a fixed state, the clamping surface 1223 is away from the mounting surface 111 and abuts against the clamping unit 123.
[0049] The setting of the clamping unit 123 enables the fixing member 1 itself to fix the bending angle of the bending unit 122. When the vehicle collides, the microphone 3 may separate from the fixing space 13 under the action of the collision force. And the clamping unit 123 can still maintain the angle of the bending unit 122 at this time, thus maintaining the abutment between the bending unit 122 and the ceiling 2. In this way, even if the microphone 3 separates from the fixing space 13, the fixing member 1 can still maintain the connection tightness with the ceiling 2, preventing it from moving toward the cockpit side through the assembly hole 21 and causing harm to the occupants, which is beneficial to improving the overall safety of the vehicle.
[0050] When the fixing member 1 is in a fixed state, the bending angle of the bending unit 122 can be 90° with respect to the thickness direction Z, minimizing the dimension of the fixing member 1 in the thickness direction Z when in a fixed state. In other embodiments, the bending angle of the bending unit 122 can be less than 90°, and the free end 1222 points away from the mask portion 11, thereby reducing the requirement for the elastic performance of the buckle portion 12. The present application does not limit this.
[0051] Further, in an optional embodiment, the bending unit 122 includes a groove 1225 provided on the clamping surface 1223. When the fixing member 1 is in the initial state, the side of the clamping unit 123 facing the mounting surface 111 is clamped with the groove 1225. The setting of the groove 1225 can optimize the size of the clamping unit 123 in the thickness direction Z. In addition, it is easy to understand that in order to achieve clamping, when the fixing member 1 switches from the initial state to the fixed state, there is a process of interference fit for the clamping unit 123. If the elasticity of the bending unit 122 is poor, it may cause the bending unit 122 or the clamping unit 123 to break during the clamping process. Therefore, the setting of the groove 1225 can also improve the elasticity of the bending unit 122, facilitate assembly, and improve the yield rate at the same time.
[0052] Similarly, in order to cooperate with the deformation of the bending unit 122 and the clamping unit 123 during the clamping process, in some embodiments, the fixing unit 121 includes a deformation hole 1211. The deformation hole 1211 is provided on the side of the fixing unit 121 close to the mounting surface 111. The setting of the deformation hole 1211 improves the elastic deformation ability of the fixing unit 121. The clamping unit 123 is assembled at one end of the fixing unit 121 away from the mounting surface 111. Therefore, when the bending unit 122 and the clamping unit 123 are clamped, the fixing unit 121 can be deformed by force, thereby driving the clamping unit 123 to deform, facilitating the realization of clamping and avoiding the clamping unit 123 from being broken by force.
[0053] The connection between the fixing member 1 and the ceiling 2 can be fixed only by the cooperation and abutment of the buckle portion 12 and the mask portion 11. In some embodiments, the bending unit 122 and the ceiling 2 can also be connected by injecting glue. The bending unit 122 includes a glue injection surface 1227. When the fixing member 1 is in the fixed state, the glue injection surface 1227 faces the mounting surface 111. By injecting and curing the glue into the gap between the glue injection surface 1227 and the ceiling 2, the connection tightness between the ceiling 2 and the fixing member 1 can be improved.
[0054] Combined Figure 4 and Figure 5 , for the convenience of injecting glue, further, the bending unit 122 may include a through glue injection hole 1226. When the fixing member 1 is in the initial state, the extending direction of the glue injection hole 1226 is different from the thickness direction Z. Thus, when the fixing member 1 is in the fixed state, the extending direction of the glue injection hole 1226 can be parallel to the thickness direction Z, or similarly, there is also a certain angle with the thickness direction Z. When the fixing member 1 is in the fixed state, the through glue injection hole 1226 facilitates the assembler to inject glue from the glue injection hole 1226, so that the glue can fill the gap between the ceiling 2 and the glue injection surface 1227, improving the connection strength between the ceiling 2 and the fixing member 1.
[0055] In an embodiment where the bending unit 122 includes a groove 1225, the cooperation between the groove 1225 and the glue injection hole 1226 can also enable the colloid to fill the groove 1225 without overflowing the clamping surface 1223. The colloid can fill the gap between the glue injection surface 1227 and the ceiling 2, the space of the glue injection hole 1226, and the space of the groove 1225. In this way, the colloid can provide a fixing force for the bending unit 122 in multiple directions and maintain the connection between the bending unit 122 and the ceiling 2.
[0056] In an embodiment where the fixing unit 121 includes a deformation hole 1211, the glue injection can also flow through the assembly hole 21 into the deformation hole 1211. Under the action of the deformation hole 1211, the required pulling force of the fixing member 1 in the thickness direction Z is further increased. In this way, the safety performance of the vehicle can also be further improved.
[0057] Reference Figure 2 , in some embodiments, in the thickness direction Z, the distance H between the bending unit 122 and the ceiling 2 is greater than or equal to 0.4 mm and less than or equal to 0.5 mm. If the distance H is too large, the corresponding amount of colloid to be filled increases, and the space required for the ceiling 2 and the fixing member 1 in the thickness direction Z increases. If the distance H is too small, the space into which the colloid can be filled is too small. The colloid usually has a certain viscosity. Under the action of surface tension, it is difficult for the colloid to flow into a too small space. Therefore, the distance H within this numerical range can optimize the occupied space of the ceiling 2 and the fixing member 1, and at the same time ensure the full flow and filling of the colloid.
[0058] To further increase the volume of the colloid between the glue injection surface 1227 and the ceiling 2, in some embodiments, at least one side edge of the glue injection surface 1227 is provided with a chamfer. Figure 3 Taking the illustrated embodiment as an example, the side edges on the left and right sides of the glue injection surface 1227 in the Figure 3 viewing angle are both provided with chamfers. In other embodiments, at least one of the left side, the right side, or one side of the free end 1222 of the glue injection surface 1227 can be provided with a chamfer. The setting of the chamfer can increase the volume of the colloid without increasing the thickness of the bending unit 122 and without increasing the distance H between the ceiling 2 and the bending unit 122, and further improve the fixing force between the fixing member 1 and the ceiling 2 and the pulling force required for the fixing member 1 to disengage from the ceiling 2.
[0059] As Figure 2 and Figure 5As shown, the ceiling 2 generally includes a substrate 22 and a decorative layer 23. The decorative layer 23 can be understood as a surface that can be seen by the occupants in the cockpit. The provision of the decorative layer 23 can improve the overall aesthetics of the vehicle, but it can be understood as not being a necessary part of the ceiling 2. The substrate 22 is generally a hard material and is used to provide support strength. In order to reduce the space occupied by the vehicle in the thickness direction Z after the ceiling 2 and the fixing member 1 are assembled, in some embodiments, the substrate 22 also includes a receiving groove 221 provided on a side away from the mounting surface 111. The receiving groove 221 is connected to the assembly hole 21. The bending unit 122 is provided in the receiving groove 221. The provision of the receiving groove 221 not only provides a storage space for the colloid, but also avoids glue overflow. In addition, this arrangement can reduce the protruding height of the bending unit 122 on the ceiling 2, and at the same time can reduce the size of the fixing unit 121 in the thickness direction Z.
[0060] In an optional embodiment, the bending unit 122 includes a bending area 1228 disposed at the connecting end 1221. In the direction from the free end 1222 to the connecting end 1221, the thickness of the bending area 1228 gradually decreases. The bending unit 122 can rotate around the connecting end 1221. The bending area 1228 with reduced thickness can improve the elasticity of the rotating area of the bending unit 122, thereby facilitating the rotation of the bending unit 122 and avoiding breakage. In addition, the gradual reduction in the thickness of the bending area 1228 can avoid the problem of weakening the strength of the bending unit 122 and easy breakage caused by the direct change in thickness. At the same time, the gradual reduction in thickness can also improve the yield rate of the buckle portion 12 during processing to a certain extent.
[0061] Figure 3 In the illustrated embodiment, the bending area 1228 is shown as an inclined transition and remains flat at the connection end 1221. However, this should be regarded as exemplary and not restrictive. The bending area 1228 can be an overall inclined transition without a flat area, or can also be an arc transition, etc. The present application is not limited to this.
[0062] refer to Figure 3 In some embodiments, the ratio of the thickness T1 of the bending area 1228 to the maximum thickness T2 of the bending unit 122 is greater than or equal to 0.45 and less than or equal to 0.55. If the thickness T1 of the bending area 1228 is too small, it is easy to cause the bending unit 122 to break when rotating. If the thickness T1 of the bending area 1228 is too large, the improvement of the elastic performance is not obvious. Since the fixing member 1 of the present application can be used to fix any components except the microphone 3, and the size differences between different components are large. Therefore, the present application can ensure the elastic ability and fracture resistance of the bending area 1228 of the fixing member 1 when fixing different components by limiting the relationship between the thickness T1 of the bending area 1228 and the maximum thickness T2 of the bending unit 122.
[0063] The elasticity of the bending unit 122 can also be improved from the perspective of materials. In some embodiments, the material of the bending unit 122 is polypropylene or polyamide. Polypropylene and polyamide have good elastic properties and good toughness, which can provide good performance support for the bending of the bending unit 122. At the same time, the toughness support of these two materials allows the bending unit 122 to be bent and reset multiple times, so after the fixing part 1 is assembled to the ceiling 2, it can also be disassembled and adjusted multiple times, reducing the cost of replacing parts during the later maintenance of the vehicle.
[0064] Similarly, the material of the mask portion 11 can also be polypropylene or polyamide. In this case, the overall material of the fixing member 1 is the same, so the fixing member 1 is a polypropylene fixing member 1 or a polyamide fixing member 1. Of course, the material of the mask portion 11 and the material of the buckle portion 12 can also be different, and the present application does not limit this.
[0065] In various embodiments of the present application, the mask portion 11 and the buckle portion 12 may be integrally formed. The integrally formed fixing member 1 has a higher overall structural strength and a higher production efficiency. In other embodiments, the mask portion 11 and the buckle portion 12 may be produced separately and then connected by bonding or the like.
[0066] It should be noted that the buckle parts 12 of the fixing member 1 shown in the drawings include two, and the two buckle parts 12 are arranged opposite to each other. This should be taken as an example and not restrictive. In other embodiments, the number of buckle parts 12 can be only one, and the anti-flipping of the fixing member 1 is achieved by the abutment between the mounting surface 111 and the ceiling 2. Alternatively, the number of buckle parts 12 can be three or four. This application is not limited to this.
[0067] In the embodiment where the fixing member 1 fixes the microphone 3, in order to improve the sound receiving quality of the microphone 3, the mask portion 11 may include a sound receiving hole 112 connected to the fixed space 13. The setting of the sound receiving hole 112 allows the sound to enter the fixed space 13 directly from the cockpit through the sound receiving hole 112, and then enter the microphone 3. In other embodiments, the sound may also enter the fixed space 13 through the gap between the mounting surface 111 and the ceiling 2.
[0068] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without causing conflicts. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
