Detailed implementation manners
[0032] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.
[0033] As Figures 1-9 shown, the car door inner panel assembly of the present invention includes an inner panel body 2 and a speaker assembly.
[0034] Specifically, as Figure 4 shown, the speaker installation assembly includes a speaker installation module 5 and a speaker body 6. The speaker installation module 5 includes an installation part 51 and a connection part 52 surrounding the outer periphery of the installation part 51. The connection part 52 is connected to the inner panel body 2, and the speaker body 6 is connected to the installation part 51.
[0035] It should be noted that the greater the stiffness of the installation point of the speaker body 6, the smaller the resonance risk between it and the inner panel body 2. Based on this, existing speakers are usually arranged adjacent to the edge position of the car door sheet metal to reduce the resonance risk between the speaker and the car door by using the high stiffness of the edge position. This limits the layout of the speakers and greatly restricts the styling of the car door interior. In this application, a speaker installation module 5 is added to the inner panel body 2. The speaker body 6 is installed on the speaker installation module 5. The speaker installation module 5 can be used as a reinforcing bracket to support the speaker body 6, thereby increasing the stiffness of the installation point of the speaker body 6, reducing the resonance risk, and releasing the constraint on the layout position of the speaker. Moreover, the speaker module can be flexibly adjusted according to requirements to meet the styling design requirements of various car door interiors.
[0036] In the car door inner panel assembly of the embodiment of the present invention, a speaker module is provided on the inner panel body 2, and a speaker body 6 is provided on the speaker module. Thus, the speaker installation module 5 can be used as a reinforcing bracket to support the speaker body 6, thereby increasing the stiffness of the installation point of the speaker body 6, reducing the resonance risk, releasing the layout constraint that the speaker must be adjacent to the car door edge, and the speaker module can be flexibly adjusted according to requirements to meet the styling design requirements of various car door interiors.
[0037] Preferably, the speaker body 6 and the speaker mounting module 5 are connected as an integral structure by bolts 8. Preferably, the speaker mounting module 5 is a plastic part, and the number of bolts 8 can be determined according to the stiffness of the door mounting point. The more bolts 8 there are, the higher the stiffness of the mounting point. Specifically, when the stiffness of the mounting point reaches 200N / mm, the risk of resonance and abnormal sound between the door and the speaker body 6 is low.
[0038] Furthermore, if Figures 4-6 As shown, the speaker installation module 5 is connected to the inner panel body 2 by bolts 8. The inner panel body 2 is provided with through holes 7. The bolts 8 pass through the through holes 7 to connect to the speaker installation module 5, and the other side of the bolts 8 is threadedly connected with the nuts. In order to ensure reliable threaded connection and convenient installation, specifically, a rivet nut is pre-installed on one side of the inner panel body 2, and the speaker installation module 5 is connected to the inner panel body 2 by bolting 8, so as to form a complete door speaker installation structure. In order to ensure reliable connection of the bolts 8, specifically, the spacing between the bolt 8 holes is between 150 and 200 mm, and a bolt 8 installation point is set every 150 to 200 mm.
[0039] In some embodiments, the inner panel body 2 includes opposite front and rear sides in the front-rear direction of the vehicle body, and the speaker mounting module 5 is disposed adjacent to the rear side. In other words, the speaker body 6 is disposed at the rear of the inner panel body 2. Compared with the front speaker, the risk of resonance between the door and the speaker body 6 is small, and because the speaker body 6 is mounted on the speaker module, the rear speaker body 6 will not interfere with the arrangement of components such as the door lock motor.
[0040] Preferably, if Figure 4 As shown, a reinforcement member 11 is provided on the inner panel body 2, and the reinforcement member 11 is adjacent to one side of the speaker mounting module 5 or surrounds the outer periphery of the speaker mounting module 5. In other words, the inner panel body 2 is locally reinforced in the area where the speaker mounting module 5 is located, further improving the rigidity of the mounting point and solving the problem of abnormal resonance of the door when the power of the speaker body 6 is relatively large.
[0041] Optionally, the reinforcement member 11 may be a reinforcement rib 9 arranged on the inner panel body 2 , or may be a reinforcement protrusion or concave large surface feature directly formed on the inner panel body 2 .
[0042] Preferably, the mounting portion 51 is spaced apart from the inner plate body 2. That is, a spacer cavity is formed between the mounting portion 51 and the inner plate body 2, thereby further reducing the risk of resonance between the two.
[0043] Preferably, if Figure 5As shown, the speaker mounting module 5 is a reinforcing plate, and a plurality of reinforcing ribs 9 are provided on the reinforcing plate. Thus, the arrangement of the reinforcing ribs 9 can further improve the structural strength of the reinforcing plate to increase the stiffness of the mounting points of the speaker body 6 and further reduce the resonance risk.
[0044] Furthermore, as Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, a sealing adhesive layer 10 is provided between the outer peripheral edge of the speaker mounting module 5 and the inner panel body 2. The inner panel body 2 is provided with a first water leakage hole 12 and a second water leakage hole 13 that penetrate the inner panel body 2. The first water leakage hole 12 is provided at the lowest point of the speaker mounting module 5 and above the sealing adhesive layer 10, and the second water leakage hole 13 is provided at the lowest point of the inner panel body 2.
[0045] It should be noted that the area between the outer door panel 1 and the inner panel body 2 is a wet area (i.e., an area where water can flow in). When the door is washed by rain or a high-pressure water gun, water will enter the wet area along areas such as the door glass guide groove. The area between the inner panel body 2 and the door trim panel 3 is a dry area (i.e., an area where water cannot enter). As Figure 2 shown, under the action of the door gravity, water generally accumulates at the lowest point of the speaker mounting module 5 ( Figure 8 shown as area A), and at the same time, the lowest point of the inner panel body 2 ( Figure 8 shown as area B) is also prone to water accumulation.
[0046] When the speaker mounting module 5 is connected to the inner panel body 2, the sealing adhesive layer 10 can achieve a tight connection between the speaker mounting module 5 and the inner panel body 2, preventing water from entering the dry area of the door. At the same time, the first water leakage hole 12 is provided at the lowest point of the speaker mounting module 5 ( Figure 8 shown as area A), and the second water leakage hole 13 is provided at the lowest point of the inner panel body 2 ( Figure 8 shown as area B), ensuring that the water flowing in the door can drain into the wet area along the water leakage holes. This structure can achieve the sealing function of the speaker mounting module 5. Since the speaker mounting module 5 is small in size relative to the large door module, the sealing measure is simple, and the sealing efficiency and function are better.
[0047] Preferably, the distance between the sealing adhesive layer 10 and the first water leakage hole 12 is a, and 1.5 mm ≤ a ≤ 2.5 mm is satisfied. Preferably, a is 2 mm. At this distance, the setting height of the first water leakage hole 12 is close to the sealing adhesive layer 10, which can avoid the problem of water accumulation and incomplete drainage.
[0048] The door assembly of the embodiment of the present invention includes an outer door panel 1, an interior trim panel, and the door inner panel assembly as described in the above embodiment. The outer door panel 1 is connected to the outer side of the inner panel body 2, the interior trim panel is connected to the inner side of the inner panel body 2, and the speaker mounting module 5 is connected to the side of the inner panel body 2 facing the interior trim panel.
[0049] For the door assembly of the embodiment of the present invention, by adopting the above-mentioned door inner panel assembly, a speaker module is provided on the inner panel body 2, and a speaker body 6 is provided on the speaker module. Thus, the speaker mounting module 5 can be used as a reinforcing bracket to support the speaker body 6, thereby improving the stiffness of the mounting point of the speaker body 6, reducing the risk of resonance, removing the layout constraint that the speaker must be arranged adjacent to the door edge, and the speaker module can be flexibly adjusted in the mounting position according to requirements to meet the styling design requirements of various door interiors.

[0051] For the vehicle of the embodiment of the present invention, by adopting the above-mentioned door assembly, a speaker module is provided on the inner panel body 2, and a speaker body 6 is provided on the speaker module.
