Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a rearview mirror folding mechanism, a rearview mirror and a vehicle. Background Art

[0002] With the rapid development of automobile technology, automobile exterior rearview mirrors are gradually moving towards a new stage of intelligence and electronicization. This change not only improves the technological content of vehicles, but also puts higher requirements on the functions and designs of rearview mirrors. As a symbol of this trend, electronic rearview mirrors not only need to have the basic functions of traditional rearview mirrors, such as clear field of view display and adaptive adjustment in rainy and foggy weather, but also emphasize the retention of manual folding function to ensure convenience and safety in specific scenarios.

[0003] However, the introduction of electronic rearview mirrors also comes with a series of design challenges. Due to its pursuit of extreme lightness and integration, the external dimensions are greatly compressed, which directly leads to the fact that traditional hand-folding mechanisms cannot be directly applied to electronic rearview mirrors due to height and size limitations. There is an irreconcilable contradiction between the design space requirements of traditional hand-folding mechanisms and the compact internal structure of electronic rearview mirrors, forcing engineers to explore a new folding mechanism.

[0004] In addition, in actual use, especially when the vehicle enters a narrow parking space or an automatic car wash machine, the folding function of the electronic rearview mirror is particularly important. However, in this process, since the electronic rearview mirror integrates a large number of precision components and is limited by its small size, the friction problem between the traditional preload spring and the contact surface during the folding process becomes particularly prominent. This friction may not only produce unpleasant noises, affecting the user experience of passengers and drivers in the car, but may also cause wear and tear on internal components in the long run, affecting the service life and performance stability of the rearview mirror.

[0039] Example 1

[0040] Combination Figure 1 , Figure 2 , Figure 5 As shown, this embodiment provides a rearview mirror folding mechanism for connecting the rearview mirror to a vehicle, including a fixing seat 100 , a rotating seat 200 , and a preload shaft 300 .

[0041] The fixing seat 100 is arranged on the vehicle, and a matching column 110 is arranged on the fixing seat 100; the rotating seat 200 is arranged on the rearview mirror, and a rotating groove 210 corresponding to the matching column 110 is opened on the rotating seat 200, and the rotating groove 210 is covered on the matching column 110, and a through groove 220 is opened at the bottom of the rotating groove 210; the preload shaft 300 is penetrated in the through groove 220, and the end of the preload shaft 300 close to the matching column 110 is matched and connected with the matching column 110, that is, the end of the matching column 110 is opened with a clamping groove, and the end of the preload shaft 300 close to the matching column 110 is provided with a clamping groove corresponding to the clamping groove The end of the preload shaft 300 close to the matching column 110 is inserted into the snap-in groove and is connected with the snap-in groove through the snap-in portion; the end of the preload shaft 300 away from the matching column 110 is provided with a limit platform 310, and an elastic member 320 is provided between the limit platform 310 and the end surface of the rotating seat 200 away from the fixed seat 100, and the elastic member 320 is used to drive the bottom of the rotating groove 210 to be squeezed and matched with the top of the matching column 110 through its own elastic force; the end surface of the rotating seat 200 close to the elastic member 320 is provided with a lubrication portion, and the lubrication portion is used to lubricate the contact position between the elastic member 320 and the rotating seat 200.

[0042] The rearview mirror folding mechanism provided in this embodiment requires, during the installation phase, that the rotating seat 200 be first installed on the rearview mirror; then, the fixed seat 100 is fixed on the vehicle as the base point for the rotation of the rearview mirror. Next, the rotating groove 210 on the rotating seat 200 is docked with the matching column 110 on the fixed seat 100; after the docking is completed, the elastic member 320 is installed on the preload shaft 300. When the preload shaft 300 passes through the through groove 220 of the rotating seat 200 and is tightly matched with the end of the matching column 110, the rotating seat 200 will move closer to the fixed seat 100 under the continuous action of the elastic member 320 until the bottom of the rotating groove 210 is tightly pressed against the end of the matching column 110, thereby realizing the rapid and stable installation of the rearview mirror.

[0043] In actual use, when the user needs to fold or open the rearview mirror according to the driving environment or parking requirements, the user only needs to gently turn the rearview mirror, and the rotating seat 200 can be rotated relative to the fixed seat 100 to adjust to the required angle. When the rearview mirror is opened to a suitable angle that the user is satisfied with, the elastic member 320 will immediately play a role, tightening the relative position of the rotating seat 200 and the fixed seat 100 to ensure that the rearview mirror will not shake due to bumps during driving, providing the user with a more stable and clear field of vision. In addition, considering the wear problem that may occur during long-term use, this embodiment is provided with a lubricating part on the end face of the rotating seat 200 close to the elastic member 320. This design allows the user to fold or open the rearview mirror, and the lubricating part can automatically lubricate the contact position between the elastic member 320 and the rotating seat 200, effectively reducing the friction caused by relative movement, thereby extending the service life of related components, and also greatly reducing the abnormal noise caused by friction, bringing a more comfortable and quiet driving experience to the user.

[0044] In some embodiments, the elastic member 320 is a preload spring, which is sleeved on the preload shaft 300. The design of this preload spring cleverly meets the requirements for elasticity and reset capability, and its structure is compact and durable. The preload spring is precisely sleeved on the preload shaft 300. This installation process not only ensures a close fit between the spring and the shaft, but also enables the spring to achieve effective buffering and reset functions through its good elastic properties when subjected to external force.

[0045] In some embodiments, the preload spring is a wave spring. As the name implies, the wave spring has a unique wave structure that allows it to provide the same or even higher preload force as a traditional spring while showing a significant space saving advantage. Specifically, compared with traditional spiral springs or leaf springs, the wave structure of the wave spring can more effectively utilize space when compressed or extended, reducing the overall design space occupied. This feature is particularly important in today's rearview mirror design that pursues compact and integrated design, because it not only helps to achieve a more complex functional layout in a limited space, but also promotes the miniaturization and lightweight development of the product, thereby enhancing the market competitiveness of the product.

[0046] In addition, due to its unique mechanical properties and material selection, wave springs can often exhibit good fatigue resistance and stability while ensuring high preload, further extending the service life and reliability of the equipment.

[0047] In some embodiments, an elastic rib parallel to the axis of the preload shaft 300 is provided on the side wall of the preload shaft 300, and a plurality of the elastic ribs are evenly distributed relative to the axis of the preload shaft 300. The distance between the end face of the elastic rib away from the preload shaft 300 and the axis of the preload shaft 300 is equal to the inner circle radius of the wave spring, so as to improve the guiding effect of the preload shaft 300 on the wave spring, avoid the wave spring from colliding with or even wearing the side wall of the preload shaft 300 during use, and ensure the reliability of the wave spring.

[0048] In some embodiments, the end surface of the rotating seat 200 close to the pre-tensioning spring is provided with a pre-tensioning groove 230 corresponding to the pre-tensioning spring, and the pre-tensioning spring is inserted into the pre-tensioning groove 230 and pressed against the bottom of the pre-tensioning groove 230; by setting the pre-tensioning groove 230 corresponding to the pre-tensioning spring, it is convenient to provide guidance for the pressing of the pre-tensioning spring, avoid the displacement of the pressing direction of the pre-tensioning spring, and ensure its reliability in use.

[0049] In some embodiments, a plurality of lubrication grooves 240 are evenly distributed at the bottom of the preload groove 230 relative to the axis of the preload shaft 300, and the plurality of lubrication grooves 240 form the lubrication portion, and the lubrication grooves 240 are filled with lubricating oil; when the preload spring contacts the bottom of the preload groove 230 and generates relative friction, the end of the preload spring can be infected with the lubricating oil in the lubrication groove 240, thereby reducing the friction between the end of the preload spring and the bottom of the preload groove 230 and reducing wear.

[0050] In some embodiments, the rotating seat 200 is provided with an oil storage chamber connected to the lubrication groove 240, and the oil storage chamber is used to store lubricating oil. A sponge layer is laid in the lubrication groove 240; by providing the sponge layer, as the lubricating oil in the lubrication groove 240 is continuously consumed, the sponge layer can absorb the lubricating oil in the oil storage chamber into the lubrication groove 240, thereby improving the service life of the lubrication part of this embodiment.

[0051] In some embodiments, a limiting protrusion 111 is provided on the side wall of the matching column 110, and a limiting opening 211 is provided at the edge of the rotating groove 210. The limiting protrusion 111 is located in the limiting opening 211 to limit the relative rotation range of the rotating groove 210 and the matching column 110, and further limit the folding and opening angle of the rearview mirror and the vehicle, thereby ensuring the normal use of the rearview mirror.

[0052] like Figure 3 , Figure 4As shown, in some embodiments, a plurality of adjustment grooves 112 are evenly opened at the end of the matching column 110 relative to its own axis, and an adjustment boss 212 matching the shape of the adjustment groove 112 is provided at the bottom of the rotating groove 210. When the rearview mirror is adjusted to different positions, the adjustment groove 112 can cooperate with different corresponding adjustment bosses 212, so that after the adjustment is completed, the relative position of the rearview mirror and the vehicle remains more stable and reliable; the area of ​​the top 213 of the adjustment boss 212 is smaller than the area of ​​the bottom of the adjustment boss 212, so that when the mounting groove rotates relative to the matching column 110, the adjustment boss 212 is easier to disengage from the adjustment groove 112 to avoid getting stuck.

[0053] In some embodiments, the fixed seat 100 and the rotating seat 200 are both hollowed out to reduce the overall mass of the embodiment.

[0054] In some embodiments, the fixed seat 100 and the rotating seat 200 are both integrally formed, so as to improve the production efficiency of the present embodiment.
