[0029] Example 1

[0030] The snap-fit ​​structure provided in this embodiment of the utility model refers to... Figures 1-5 The snap-fit ​​structure snaps the fitting 1 and the door panel body 2 together. In this embodiment, the fitting 1 is a vehicle trim strip, specifically a speaker trim strip. The trim strip is connected to the door panel body 2 via the snap-fit ​​structure, forming a cavity 3 between the fitting 1 and the door panel body 2. In this embodiment, the door panel body 2 is provided with a strip-shaped protruding structure for installing the fitting 1. One end of the strip-shaped protruding structure has an opening, and the shape of the protruding structure matches the shape of the fitting 1. During installation, the fitting 1 is placed at the opening of the strip-shaped protruding structure. The cavity 3 between the fitting 1 and the door panel body 2 provides snap-fit ​​and mounting for the snap-fit ​​structure. The mounting space and the snap-fit ​​structure include a first connector 4 and a second connector 5, both of which are located within the cavity 3. The first connector 4 is connected to the mounting part 1, and the second connector 5 is installed on the door panel body 2. Within the cavity 3, the first connector 4 and the second connector 5 snap-fit ​​together, fixing the mounting part 1 to the door panel body 2. Since the snap-fit ​​structure is located within the cavity 3, there is no need to open mounting holes on the door panel body 2 or the mounting part 1, which can maintain the flatness of the door panel body 2 and the mounting part 1 structure. When touched, the touch area is flat, improving the perceived quality for occupants.

[0031] In one embodiment, refer to Figure 3 and Figure 4 The first connector 4 has a snap-fit ​​part 41 at the end away from the assembly 1, and the second connector 5 has a mating part 51. The snap-fit ​​surface 41 and the mating part 51 are mated and fixed together.

[0032] Specifically, the first connector 4 has a snap-fit ​​part 41 at the end away from the assembly 1, and the second connector 5 has a mating part 51. In this embodiment, the snap-fit ​​part 41 is a protrusion protruding from the outer wall of the first connector 4 or a limiting hole opened on the first connector 4. The mating part 51 is a limiting hole or protrusion on the second connector 5 that mates with the snap-fit ​​part 41. The protrusion snaps with the inner wall of the limiting hole. When the first connector 4 is connected to the second connector 5, the first connector 4 gradually moves toward the second connector 5 along the assembly direction. During the movement, the first connector 4 abuts against the second connector 5 until the snap-fit ​​part 41 and the mating part 51 are mated and fixed, thus fixing the assembly 1 to the door panel body 2. In this embodiment, the snap-fit ​​structure is set in the cavity 3 between the assembly 1 and the door panel body 2, avoiding direct opening on the door panel body 2 and ensuring the flatness of the surface of the door panel body 2.

[0033] In one embodiment, the second connector 5 includes a guide portion 52 and a fixing portion 53. The guide portion 52 is fixed to the door panel body 2 by the fixing portion 53, and the mating portion 51 is a limiting hole opened on the fixing portion 53.

[0034] Specifically, refer to Figure 4 The second connector 5 includes a guide portion 52 and a fixing portion 53. The fixing portion 53 is connected to the door panel body 2, and the guide portion 52 is fixed to the door panel body 2. In this embodiment, the mating portion 51 is a limiting hole, which is opened on the fixing portion 53. At this time, the snap-fit ​​portion 41 is a protrusion protruding from the outer wall of the first connector 4, and the snap-fit ​​portion 41 is limited in the mating portion 51 to achieve mating fixation. The fixing portion 53 is connected to the door panel body 2, and the mating portion 51 is set close to the door panel body 2, which ensures the connection strength between the snap-fit ​​portion 41 and the mating portion 51.

[0035] In one embodiment, refer to Figure 2 Along the first direction, the width of the guide portion 52 away from the fixing portion 53 is smaller than its width near the fixing portion 53.

[0036] Specifically, the first direction is the direction of movement of the second connecting member 5 when the first connecting member 4 and the second connecting member 5 are fixed together. Specifically, it refers to the straight line direction perpendicular to the plane where the door panel body 2 is located. The guide part 52 is away from the door panel body 2 relative to the fixing part 53. The width of the guide part 52 away from the fixing part 53 is smaller than its width close to the fixing part 53. Therefore, the outer wall of the guide part 52 is an inclined structure. When fixed together, the snap-fit ​​part 41 first contacts the guide part 52 with the smaller width. When the snap-fit ​​part 41 gradually moves to the mating part 51, the position where the guide part 52 has the largest width abuts against the snap-fit ​​part 41, ensuring the fixing effect between the guide part 52 and the snap-fit ​​part 41.

[0037] In one embodiment, refer to Figure 3The snap-fit ​​part 41 is provided with a guide slope 42, the guide slopes 42 are arranged opposite each other and there is a gap between the guide slopes 42, and the guide part 52 snaps into the snap-fit ​​part 41 along the gap.

[0038] Specifically, guide slopes 42 are arranged opposite to each other on both sides of guide portion 52, with gaps between them. When the first connector 4 and the second connector 5 are engaged, guide portion 52 passes through the gaps between guide slopes 42. Multiple guide slopes 42 provide guide channels for guide portion 52, achieving a guiding effect and facilitating engagement installation. It should be noted that guide slopes 42 are arranged on engagement portion 41, so engagement portion 41 is also arranged opposite to each other. When guide portion 52 is engaged with 41, engagement portion 41 falls into the mating portion 51 opened by the second connector 5. Multiple engagement portions 41 arranged opposite to each other engage guide portion 52 simultaneously, improving the stability of the installation and fixing between the first connector 4 and the second connector 5, and ensuring that the assembly 1 is securely fixed to the door panel body.

[0039] In one embodiment, refer to Figure 3 The assembly 1 includes an assembly plate body 11 and an extension 12. The extension 12 is arranged circumferentially along the assembly plate body 11, and the outer wall of the extension 12 is fitted with the inner wall of the door panel body 2.

[0040] Specifically, the fitting 1 is a decorative strip, including a mounting plate body 11 and an extension 12. When the fitting 1 is installed on the door panel body 2, a cavity 3 is formed between the fitting 1 and the door panel body 2. Assuming that the door panel body 2 is provided with a protruding structure that matches the fitting 1, the mounting plate body 11 in the fitting 1 is located at the opening position of the protruding structure provided in the door panel body 2. The extension 12 extends into the cavity 3 to fill the cavity. Preferably, the height of the extension 12 extending into the cavity 3 is the same as the depth of the cavity 3. The extension 12 can be used to support the mounting plate body 11, keeping the mounting plate body 11 and the door panel body 2 on the same plane, further ensuring the flatness of the structural surface and improving the tactile feel of the occupants.

[0041] In one embodiment, refer to Figure 3 An opening 12-1 is provided on the extension 12. The opening 12-1 is disposed opposite to each other on both sides of the first connector 4. When the first connector 4 and the second connector 5 are engaged, the second connector 5 extends into the opening 12-1.

[0042] Specifically, an opening 12-1 is provided on the extension 12, and the opening 12-1 is disposed opposite to each other on both sides of the first connector 4. In the embodiment, the second connector 5 extends on the door panel body 2 to both ends of the cavity 3, and the extension 12 is disposed circumferentially on the mounting part 1. When the first connector 4 and the second connector 5 are engaged, the first connector 4 moves along the assembly direction to the engaging part 41 and extends into the mating part 51. At this time, the extension 12 also moves along the assembly direction toward the door panel body 2. When the extension 12 moves, the opening 12-1 provides movement space for the second connector 5.

[0043] In one embodiment, the width of at least one opening 12-1 along the second direction is adapted to the width of the second connector 5 along the second direction.

[0044] Specifically, the second direction is perpendicular to the first direction. The second direction is the width direction of the second connector 5. The width of the opening 12-1 along the second direction is the diameter of the opening 12-1 on the extension 12. The width of the opening 12-1 along the second direction is adapted to the width of the second connector 5 along the second direction. Then, the outer wall of the second connector 5 abuts against the inner wall of the opening 12-1, which can limit the second connector 5 in the second direction.

[0045] The snap-fit ​​structure proposed in this embodiment works as follows: a first connector 4 is provided on the assembly 1, and a second connector 5 is provided on the door panel body 2. A cavity 3 is provided between the assembly 1 and the door panel body 2. In the cavity 3, the first connector 4 moves toward the door panel body 2, and the guide portion 52 on the second connector 5 moves relative to the guide inclined surface 42 on the first connector 4. After the first connector 4 and the second connector 5 move relative to each other to a predetermined distance, the snap-fit ​​portion 41 and the mating portion 51 cooperate and fix them. The snap-fit ​​portion 41 and the mating portion 51 form a force-bearing cooperation, so that the assembly 1 can be fixed on the door panel body 2. In this embodiment, the first connector 4 and the second connector 5 are both provided in the cavity 3 between the assembly 1 and the door panel body 2. The cooperation and fixation between the first connector 4 and the second connector 5 can achieve the effect of fixing the assembly 1 and the door panel body 2. The snap-fit ​​structure of this embodiment does not require the opening of mounting holes on the door panel body 2, thus ensuring the flatness of the door panel body 2.

[0048] Since the car door includes a snap-fit ​​structure, a fitting 1, and a door panel body 2, a storage slot 6 is provided on the side of the door panel body 2 near the interior of the vehicle. The storage slot 6 is a cavity provided on the door panel body 2 to provide space for passengers to place their items. The fitting 1 is set on the inner wall of the storage slot 6 and is fixed to the door panel body 2. An opening is provided at the top of the cavity, and the passenger's hand can enter the cavity through the opening, so that they can touch the door panel body 2. By setting the snap-fit ​​structure in the cavity 3 formed between the fitting 1 and the door panel body 2, the cavity 3 provides installation space for the snap-fit ​​structure, so that there is no need to open an installation hole on the door panel body 2, thus avoiding affecting the tactile feel.
