Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a sunshade with a retractable rotating shaft. Background Art

[0002] As a standard accessory on the vehicle, the sun visor is usually installed on the driver and co-driver seats. It is used to block the light that passes through the windshield and side windows and affects safe driving, effectively avoiding driving risks and improving driving safety.

[0003] However, the existing sun visors on the market generally include a sun visor body, a rotating shaft and a base, the base is installed on the vehicle, one end of the rotating shaft is rotatably installed on the base, and the other end of the rotating shaft extends into the sun visor body and is rotatably connected, so that the sun visor body can rotate relative to the rotating shaft, and at the same time, the rotating shaft can rotate relative to the base, thereby realizing the multi-angle arrangement of the sun visor body, which can not only block the light irradiated from the front windshield direction, but also block the light irradiated from the side window direction. For example, the automobile sun visor disclosed in patent CN103895471A includes a base and a rotating shaft fixed on the base, and a U-shaped retaining spring clamped on the rotating shaft, and the U-shaped retaining spring is fixedly connected to the sun visor body, so that the sun visor body can not only rotate relative to the rotating shaft through the U-shaped retaining spring, but also realize the rotation of the rotating shaft on the base, meeting the use requirements of the sun visor. Although the existing sun visors are able to block light, the size of the sun visor body is limited by the space of its installation position, and the base is installed near the windshield, so that when the sun visor is turned to block the side windows, the sun visor body extends along the A-pillar toward the B-pillar of the vehicle. However, since the seats of the driver and passengers are close to the B-pillar of the vehicle, the end of the sun visor body extending toward the B-pillar cannot completely block the facial area of ​​the driver and passenger, and the driver and passenger will not be located at the end of the sun visor body close to the A-pillar, which results in the existing sun visor having a poor effect in blocking light from the side windows, affecting the user experience.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 4 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0024] Figure 1 FIG. 1 is a structural diagram of an embodiment of a sunshade with a retractable rotating shaft according to the present invention. Figure 1 As shown, the sun visor with a retractable shaft provided in this embodiment includes: a sun visor body 1, a shaft 2, a base 3 and a retractable assembly 4. At this time, similar to the structure of a traditional sun visor, the base 3 is installed on the vehicle frame to achieve stable installation of the sun visor on the vehicle. At the same time, one end of the shaft 2 is rotatably installed on the base 3, and the sun visor body 1 is arranged on the other end of the shaft 2, so that the shaft 2 can deflect on the base 3, and the sun visor body 1 can deflect on the shaft 2, thereby meeting the use requirements of blocking light in different states.

[0025] Specifically, the telescopic assembly 4 is arranged between the rotating shaft 2 and the sun visor body 1, that is, the telescopic assembly 4 is used as a connecting structure between the rotating shaft 2 and the sun visor body 1, which provides conditions for the sun visor body 1 to move on the rotating shaft 2. At this time, the telescopic assembly 4 also includes a telescopic sleeve 41, a telescopic seat 42 and a retaining spring 43. During installation, the telescopic sleeve 41 is arranged along the length direction of the sun visor body 1, and the telescopic sleeve 41 is fixed on the sun visor body 1, that is, a sliding cavity arranged along the length direction is provided on the sun visor body 1 through the telescopic sleeve 41, which provides conditions for the subsequent sliding of the sun visor body 1 along the length direction. In addition, the arrangement direction of the telescopic sleeve 41 is also consistent with the axial direction of the rotating shaft 2, so that the subsequent movement direction of the sun visor body 1 is the axial direction of the rotating shaft 2, thereby realizing the position adjustment of the sun visor body 1 relative to the rotating shaft 2, thereby changing the withdrawal distance of the sun visor body 1 to meet different usage requirements. In addition, a telescopic holder 42 is slidably arranged in the telescopic sleeve 41 to reciprocate along the arrangement direction of the telescopic sleeve, so that the telescopic holder 42 can slide along the length direction of the sun visor body 1, that is, it can also slide along the axial direction of the rotating shaft 2, which provides conditions for the subsequent axial adjustment of the sun visor body 1 along the rotating shaft 2. At the same time, a clamping spring 43 is installed on the telescopic holder 42. During installation, the end of the rotating shaft 2 connected to the sun visor is inserted into the telescopic sleeve 41 to ensure the connection between the rotating shaft 2 and the telescopic holder 42. At this time, the telescopic holder 42 is rotatably sleeved outside the rotating shaft 2, that is, the rotating shaft 2 can rotate relative to the telescopic holder 42, thereby meeting the use requirement of the sun visor body 1 flipping on the rotating shaft 2. At the same time, the telescopic holder 42 can maintain a stable position in the axial direction of the rotating shaft 2, that is, when the sun visor body 1 and the rotating shaft 2 move relative to each other, it can be achieved by the telescopic holder 42 sliding in the telescopic sleeve 41. In addition, the retaining spring 43 is brought into contact with the outer wall of the rotating shaft 2, and the rotating shaft 2 is pressed tightly by the retaining spring 43, providing a pre-tightening force for the rotation of the rotating shaft 2, thereby maintaining the state of the sun visor after flipping over to meet the use requirements.

[0026] More specifically, the telescopic sleeve 41 is set to a flat cylindrical structure, so that the telescopic sleeve 41 has a thinner thickness and a wider width, which can not only meet the installation requirements on the thinner sun visor body 1, but also provide a sufficiently large sliding space, providing conditions for the stable installation of the subsequent telescopic card seat 42. In addition, the inner wall of the telescopic sleeve 41 has a plurality of first guide surfaces extending along its length direction, so that the first guide surfaces can cover the length of the telescopic sleeve 41, thereby adapting to the sliding stroke of the subsequent telescopic card seat 42. In addition, a plurality of second guide surfaces 4221 cooperating with the first guide surfaces are arranged on the outer side wall of the telescopic card seat 42, so that when the telescopic card seat 42 slides in the telescopic sleeve 41, it can be guided by the cooperation of the first guide surface and the second guide surface 4221, ensuring the stability of the telescopic card seat 42 when sliding in the telescopic sleeve 41, and the structural design is more reasonable.

[0027] More specifically, outwardly protruding step portions 421 are provided at both ends of the telescopic card seat 42, and protruding portions can be formed at both ends of the telescopic card seat 42 through the step portions 421. At this time, a plurality of outwardly protruding contact blocks 422 are provided on the outer wall of each step portion 421, and the outer surface of the contact block 422 is set as the second guide surface 4221, that is, the contact area between the telescopic card seat 42 and the inner wall of the telescopic sleeve 41 is reduced by the arrangement of the step portions 421, and the arrangement of the contact blocks 422 further reduces the contact area of ​​the step portions 421 contacting the inner wall of the telescopic sleeve 41, thereby reducing the friction force of the telescopic card seat 42 when sliding in the telescopic sleeve 41, and it is more convenient to use.

[0028] Figure 2 This is a structural diagram of the cooperation between the telescopic card seat and the rotating shaft in a preferred embodiment of the utility model; Figure 3 This is a structural diagram of a telescopic card holder of a preferred embodiment of the utility model after removing the cover. Figure 1 , Figure 2 as well as Figure 3 As shown, the telescopic seat 42 for sliding in the telescopic sleeve 41 includes a sliding seat 423 and a cover body 424. During installation, the sliding seat 423 is slidably arranged in the telescopic sleeve 41 along the length direction of the telescopic sleeve 41 to meet the use requirements of the telescopic seat 42 sliding in the telescopic sleeve 41. At this time, the two ends of the sliding seat 423 are respectively protruded toward the same side to form two rings with central sliding holes. At the same time, the central sliding holes of the two rings are arranged opposite to each other, so that when the rotating shaft 2 is subsequently connected to the telescopic seat 42, the end of the rotating shaft 2 can pass through the central sliding holes of the two rings in turn, ensuring that the rotating shaft 2 and the sliding seat 423 are connected at two points, and the connection stability is higher. It is worth pointing out that the two rings are the two step portions 421 recorded above, which can not only reduce friction, but also serve as a structure connected to the rotating shaft 2. At this time, the cover body 424 is arranged between the two rings and covers the rotating shaft 2 located between the two rings, so that the integrity of the telescopic seat 42 is better.

[0029] More specifically, the spring clip 43 in the telescopic seat 42 is an arc-shaped structure, and at this time, the middle part of the spring clip 43 is arranged to protrude toward one side. During subsequent installation, the spring clip 43 is arranged on the sliding seat 423 and between the two rings, so that the spring clip 43 can follow the sliding seat 423 to move, thereby adapting to the use requirements of the telescopic seat 42 sliding in the telescopic sleeve 41. In addition, there are intervals between the two ends of the spring clip 43 and the two rings. At the same time, the middle part of the spring clip 43 is protruded toward one side of the rotating shaft 2 and abuts against the outer wall of the rotating shaft 2. The intervals at the two ends of the spring clip 43 provide an avoidance space for the deformation of the spring clip 43, ensuring the normal deformation of the spring clip 43. At the same time, the spring clip 43 provides a pre-tightening force for the rotating shaft 2, so that the rotating shaft 2 can be pre-tightened by the spring clip 43 after rotating relative to the telescopic seat 42, thereby maintaining the state of the middle sun visor body 1, and the structural design is more reasonable.

[0030] More specifically, a limiting plane is further provided on the outer wall of the rotating shaft 2 located between the two rings, and when the retaining spring 43 is matched with the rotating shaft 2, the limiting plane on the rotating shaft 2 is misaligned with the middle part of the retaining spring 43 or the limiting plane on the rotating shaft 2 is in close contact with the middle part of the retaining spring 43. When the two are in close contact, surface limiting can be achieved by fitting the limiting plane and the plane on the retaining spring 43, thereby improving the stability of the limiting. It can be used as a limiting structure when the sun visor body 1 is in a closed state, thereby improving the stability of maintaining the sun visor in a closed state.

[0031] Figure 4 This is a structural diagram of a sliding seat of a preferred embodiment of the utility model. Figures 1 to 4 As shown, both sides of the sliding seat 423 of the telescopic seat 42 are provided with elastic abutment parts 4231. At this time, the elastic abutment parts 4231 are arranged along the axial direction of the rotating shaft 2 to adapt to the moving direction of the sliding seat 423. At the same time, the elastic abutment parts 4231 are designed to be strip-shaped structures, so that the elastic abutment parts 4231 have a certain length, which provides conditions for the subsequent elastic abutment parts 4231 to have elastic force. In addition, one end of the elastic abutment part 4231 is fixed to both sides of the sliding seat 423. Preferably, the elastic abutment part 4231 and the sliding seat 423 are an integrated structure with higher structural strength. In addition, the other end of the elastic abutment part 4231 is extended obliquely toward the side away from the sliding seat 423, so that there is a gap between the other end of the elastic abutment part 4231 and the sliding seat 423, thereby ensuring that the other end of the elastic abutment part 4231 is a suspended end to meet the deformation requirements. In addition, when the telescopic seat 42 is installed in the telescopic sleeve 41, one end of the elastic abutment 4231 extends against the inner wall of the telescopic sleeve 41, that is, the telescopic seat 42 contacts the inner wall of the telescopic sleeve 41 through the elastic abutment 4231, which facilitates disassembly and assembly, while also ensuring stability during sliding, and ensuring that the elastic abutment 4231 can still stably contact the inner wall of the telescopic sleeve 41 through deformation after long-term use, thereby extending the service life.

[0032] More specifically, limiting grooves 4241 arranged tangentially along the rotating shaft 2 are provided on both sides of the cover body 424, so that the arrangement direction of the limiting grooves 4241 is consistent with the deformation direction of the retaining spring 43. At the same time, limiting blocks 431 respectively extending into the two limiting grooves 4241 are provided on both sides of the retaining spring 43. When the force acting on the retaining spring 43 changes and causes the retaining spring 43 to deform, the retaining spring 43 can slide in the limiting grooves 4241 through the limiting blocks 431 on both sides thereof to improve the stability of the retaining spring 43 during deformation, and the structural design is more reasonable.

[0033] More specifically, the cross section of the cover 424 is arranged in a "U" shape, so that the cover 424 has a cavity with an opening. At this time, the open end of the cover 424 is arranged toward the sliding seat 423, and the rotating shaft 2 is located in the cavity of the cover 424, so as to cover the rotating shaft 2. In addition, clamping holes 4242 are provided on both sides of the open end of the cover 424, and a clamping plate 425 is provided between the sliding seat 423 and the clamping spring 43. Since the side of the clamping spring 43 away from the sliding seat 423 abuts against the rotating shaft 2, the clamping spring 43 can press the clamping plate 425, so as to achieve stable installation of the clamping plate 425 on the sliding seat 423. In addition, clamping feet 4251 cooperating with the clamping holes 4242 are provided on both sides of the clamping plate 425, that is, the clamping feet 4251 are clamped into the clamping holes 4242 to achieve a clamping connection between the cover body 424 and the clamping plate 425, thereby achieving the installation of the cover body 424 on the sliding seat 423 to meet the installation requirements.

[0034] The sun visor with a retractable shaft provided in the present embodiment includes a sun visor body 1, a shaft 2, a base 3 and a retractable component 4; a retractable sleeve 41 with the retractable component 4 arranged along its length direction is provided in the sun visor body 1, and a retractable seat 42 is slidably provided in the retractable sleeve 41, one end of the shaft 2 is rotatably installed on the retractable seat 42, and the other end is rotatably installed on the base 3, so that the sun visor body 1 can be tilted and flipped relative to the base 3 through the shaft 2, meeting the use requirements of traditional sun visors, and the retractable seat 42 can be moved in the retractable sleeve 41 to achieve adjustment of the position of the sun visor body 1 relative to the base 3, thereby changing the distance between the end of the sun visor body 1 and the base 3, so that the sun visor body 1 can be adjusted to a position closer to the B-pillar of the vehicle, better meeting the shielding of the facial area of ​​​​the driver and occupant near the B-pillar of the vehicle, and further improving the shielding effect of the light irradiated from the side windows.

[0035] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention.
