[0038] Reference Figure 1 , Figure 2 The first aspect of this utility model provides a mask and lens housing connection structure, including a claw 100 and a boss 200. The claw 100 is disposed on the mask 300 and the boss 200 is disposed on the lens housing 400. The claw 100 and the boss 200 are engaged to assemble the mask 300 and the lens housing 400 together.

[0039] Reference Figure 2 , Figure 5In some embodiments, the boss 200 is provided on the back of the lens housing 400. The boss 200 is provided with a receiving groove 210. The bottom of the boss 200 is provided with a snap-fit ​​hole 220, which communicates with the receiving groove 210. The snap-fit ​​part 110 passes through the snap-fit ​​hole 220 and snaps into the boss 200. The end of the claw 100 is located in the receiving groove 210. Thus, the user cannot see the claw 100 through the assembly gap between the lens and the edge of the lens housing 400. This achieves the hiding of the claw 100 from the visible surface after assembly, eliminating the need to use a masking process to treat the claw 100, reducing production steps and manufacturing costs.

[0040] Reference Figure 4 , Figure 6 In some embodiments, the snap-fit ​​hole 220 allows the snap-fit ​​part 110 to be inserted from the bottom of the boss 200 and enter the receiving groove 210 through the snap-fit ​​hole 220 to complete the snap-fit, facilitating operation and positioning during assembly. Specifically, during the insertion of the snap-fit ​​part 110 along the central axis of the snap-fit ​​hole 220, the hole wall of the snap-fit ​​hole 220 can provide initial guidance for the claw 100, ensuring that the snap-fit ​​part 110 accurately enters the receiving groove 210 and avoids deviation. At the same time, the communication between the snap-fit ​​hole 220 and the receiving groove 210 allows the base 111 of the snap-fit ​​part 110 to pass through the snap-fit ​​hole 220, and the extension 112 to unfold in the receiving groove 210. The limiting step 113 formed by the width difference between the base 111 and the extension 112 engages with the boss 200, realizing the assembly of the mask 300 and the mirror housing 400.

[0041] Reference Figure 3 , Figure 4 In some embodiments, the claw 100 includes a locking portion 110, which includes a base 111 and an extension 112 connected to the base 111. The width of the extension 112 is greater than the width of the base 111, forming a limiting step 113 between the base 111 and the extension 112. The limiting step 113 engages with the boss 200. When the locking portion 110 is inserted into the receiving groove 210, the limiting step 113 engages with the boss 200, thereby limiting the boss 200 and preventing the claw 100 from dislodging from the receiving groove 210, ensuring the reliability of the connection between the mask 300 and the mirror housing 400.

[0042] Reference Figure 4 , Figure 6In some embodiments, the extension 112 of the snap-fit ​​portion 110 is provided with a guide ramp 114 to guide and limit the step 113 to snap into the boss 200. Specifically, the guide ramp 114 of the extension 112 can form a guide structure when the claw 100 is inserted into the receiving groove 210. When the extension 112 contacts the edge of the snap-fit ​​hole 220, the inclination angle of the guide ramp 114 can guide the claw 100 to move in a preset direction, reducing frictional resistance during insertion, avoiding damage to the claw 100 or the boss 200 due to hard collision, and improving assembly smoothness.

[0043] Reference Figure 4 In some embodiments, at least two locking portions 110 are provided, and the two locking portions 110 can be set symmetrically to improve the force balance of the claws 100, avoid excessive force on a single point leading to locking failure, and improve the torsional and tensile strength of the connection structure. Of course, in other embodiments, the number of locking portions 110 can also be set to three or four, etc. In actual design, the number of locking portions 110 can be designed according to actual needs.

[0044] Reference Figure 4 , Figure 6 In some embodiments, a reinforcing portion 120 is provided between the two latching portions 110. The reinforcing portion 120 is used to enhance the structural strength of the latching portion 110 and prevent it from breaking or loosening due to the latching portion 110 being subjected to force alone. In addition, along the central axis of the claw 100, the height of the reinforcing portion 120 is less than the height of the base 111. When the latching portion 110 is deformed under force, it can provide sufficient deformation space. When it is necessary to disassemble the latching portion 110 and the boss 200, the operator applies external force to deform the latching portion 110 in the direction of the reinforcing portion 120, thereby reducing the latching force between the latching portion 110 and the boss 200, allowing the latching portion 110 to disengage from the receiving groove 210, and reducing the difficulty of disassembly.

[0045] Reference Figure 4 In some embodiments, the claw 100 further includes a base 130 connected to the face shield 300, and a locking portion 110 is disposed on the top of the base 130. The base 130 supports the locking portion 110 and can limit the shaking or displacement of the locking portion 110 under force. For example, when the rearview mirror is subjected to vibration or external impact during vehicle operation, the base 130 can stabilize the position of the locking portion 110, ensuring that its engagement with the boss 200 is always in a reliable state.

[0046] Reference Figure 3 , Figure 6In some embodiments, the edge of the snap-fit ​​hole 220 is provided with a guide flange 230, and the guide flange 230 is located on the side of the snap-fit ​​hole 220 away from the receiving groove 210. The guide flange 230 is used to guide the snap-fit ​​claw 100 to engage with the boss 200. Specifically, the width of the guide flange 230 gradually decreases along the direction close to the snap-fit ​​hole 220, thereby forming a guide surface 240. When the snap-fit ​​claw 100 is inserted into the snap-fit ​​hole 220, the guide surface 240 can generate a guiding force on the extension 112 of the snap-fit ​​claw 100, so that the guide slope 114 of the extension 112 can slide into the hole along the guide surface 240 of the guide flange 230, reducing the positioning difficulty during assembly. In addition, the guide flange 230 can constrain the movement trajectory of the claw 100 through its edge when the claw 100 engages with the boss 200, ensuring that the claw 100 smoothly reaches the receiving groove 210 and engages with the boss 200, reducing the possibility of incomplete engagement.

[0047] Reference Figure 3 , Figure 6 In some embodiments, reinforcing ribs 250 are provided on opposite sides of the guide flange 230 to enhance the structural strength of the guide flange 230. When the claw 100 is inserted into the snap-fit ​​hole 220, the guide flange 230 bears the squeezing and pushing force of the claw 100. The reinforcing ribs 250 can disperse this force, preventing the guide flange 230 from breaking due to excessive force at a single point, thereby enhancing the structural strength of the guide flange 230.

[0048] Reference Figure 3 , Figure 6 In some embodiments, an opening 260 is provided on one side of the boss 200, which communicates with the receiving groove 210 to facilitate the engagement of the claw 100 with the boss 200. During disassembly, the opening 260 provides space for external force to act, and the operator can apply force from the opening 260 with a tool to make the claw 100 more easily disengage from the receiving groove 210, reducing the difficulty of disassembly; in addition, the design of the opening 260 can simplify the mold structure of the boss 200, reducing mold cost and processing difficulty.

[0049] In some embodiments, both the face mask 300 and the mirror housing 400 are manufactured using injection molding. Injection molding can form complex geometric structures in one step using a mold, such as the curved shape of the face mask 300, the mounting slots and hollow designs of the mirror housing 400, etc., reducing the steps and material waste of traditional machining, improving production efficiency, and meeting the needs of large-scale production. In addition, the injection molding process can precisely control the dimensional tolerances of the parts, enabling the jaws 100 of the face mask 300 and the bosses 200 of the mirror housing 400 to achieve a high-precision match, avoiding assembly gaps or interference caused by dimensional deviations, ensuring the reliability of the engagement between the jaws 100 and the bosses 200, and the sealing and waterproof performance of the face mask 300 and the mirror housing 400.

[0050] The second aspect of this utility model provides a rearview mirror, including the mask and mirror housing connection structure of the first aspect of this utility model. The user cannot observe the claw 100 through the assembly gap between the lens and the edge of the mirror housing 400, thereby realizing that the claw 100 is hidden from the visible surface after assembly, improving the overall aesthetics and quality of the product.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
