Description

Technical Field

[0001] This application relates to the field of vehicle accessory technology, specifically to a vehicle sun visor sleeve connection structure. Background Technology

[0002] The core function of a vehicle sun visor is to block sunlight and prevent direct light from shining into specific areas inside the vehicle. Existing sun visors have support rods that pass through sleeves and are connected to the vehicle's driver's seat roof via the sleeves (such as a snap-fit ​​connection) so that the sun visor can be rotated and connected above the driver's seat.

[0003] The sun visor has an internal channel for the support rod to pass through. A concave opening is provided along the extension path of this channel, for assembling a mounting sleeve. Through holes communicating with the channel are provided on both side walls of the concave opening. When the mounting sleeve is fixedly assembled within the concave opening, the support rod can pass through the through holes and the sleeve sequentially, achieving a connection between the support rod and the sun visor. The sleeve is typically installed in the concave opening using a snap-fit ​​connection; specifically, a hook is provided on one side of the sleeve corresponding to the concave opening. Due to the material properties of this hook, it is prone to softening at high temperatures, leading to a significant decrease in its structural strength and thus failing to meet the product's preset pull-out force requirements. See also... Figure 7 As shown, under these conditions, when the sun visor is used in high-temperature environments, the sleeve is prone to detaching from the concave opening. Especially when the vehicle is moving, experiencing bumps, or braking, the sleeve is easily detached from the concave opening due to the impact force. A sun visor that has detached from the sleeve will suddenly shake or even fall off completely, not only generating abnormal noise and affecting the driving experience, but also interfering with the driver's normal operation due to the irregular movement of the sun visor, posing a direct threat to driving safety. Furthermore, in extreme scenarios of a vehicle collision, an unsecured sun visor can become a dangerous projectile, impacting the occupants at high speed (especially the driver in the driver's seat), causing secondary injuries and seriously endangering the lives of the occupants. Utility Model Content

[0004] In view of the above problems, this application provides a vehicle sun visor sleeve connection structure to solve the problem that the sleeve of the existing vehicle sun visor is prone to detachment.

[0005] To achieve the above objectives, the inventors provide a vehicle sun visor sleeve connection structure, which includes:

[0006] At least one sleeve, one side of which has a through first channel along a first direction, and the other side has at least one hook;

[0007] A sun visor has a second channel along a first direction, and a slot for installing a sleeve is provided along a second direction corresponding to a portion of the path of the second channel. The first direction and the second direction are intersected. The sun visor has a cavity corresponding to the slot, and the bottom of the cavity corresponding to the slot has an opening leading to the cavity. A stop block and a seat are provided in the cavity corresponding to the hook, and there is a gap between the stop block and the seat.

[0008] The sleeve moves toward the slot in the second direction, the hook passes through the opening and engages with the card seat through the gap, the first channel and the second channel are connected; and the stop block and the hook form abutment, so that the stop block stops the movement of the hook away from the card seat.

[0009] Furthermore, the sleeve is provided with two hooks, and the cavity is provided with a locking seat for each hook to engage with it; the two hooks are symmetrically arranged along the second direction.

[0010] Furthermore, the two hooks are arranged in an outward V-shape.

[0011] Furthermore, the stop block is positioned between the two hooks.

[0012] Furthermore, the gap between the stop block and the card holder gradually decreases along the second direction.

[0013] Furthermore, the card holder is strip-shaped; one end of the card holder near the opening is fixed in the cavity, while the other end is in a suspended free state.

[0014] Furthermore, when the hook passes through the opening and engages with the card seat through the gap, the engaging contact surfaces of the hook and the card seat are completely in contact.

[0015] Furthermore, the first direction and the second direction are set perpendicularly.

[0016] Furthermore, the sleeve extends outward from the slot with a connecting plate, and the outer surface of the sunshade is provided with a relief groove corresponding to the connecting plate; when the hook passes through the opening and engages with the card seat through the gap, the connecting plate and the relief groove form a surface connection.

[0017] Furthermore, the sun visor includes an upper shell and a lower shell, which are connected to form a cavity;

[0018] The corresponding cavity of the card slot is located in the upper shell and / or the lower shell;

[0019] Alternatively, the cavity corresponding to the stop block may be located in the upper shell and / or lower shell.

[0020] Unlike existing technologies, the above-mentioned technical solution has a stop block at a corresponding position on the back side of the hook. The position of the stop block is adapted to the movement trajectory of the hook. When the sleeve is engaged with the sun visor's seat through the hook, the stop block can effectively limit the hook, that is, directly stop the hook's displacement movement away from the seat, thereby limiting the excessive deformation of the hook and preventing the hook from deforming and loosening due to the decrease in the elastic modulus of the material under high temperature conditions. This ensures the stability and reliability of the connection structure between the sleeve and the sun visor.

[0056] See Figures 1-6 As shown, a vehicle sun visor sleeve connection structure is provided to solve the technical problem that the sleeve 20 of the vehicle sun visor 10 is prone to detachment in the prior art. A stop block 105 is provided at a corresponding position on the back side of the hook 202. The arrangement position of the stop block 105 is adapted to the movement trajectory of the hook 202. When the sleeve 20 is engaged with the seat 104 of the sun visor 10 through the hook 202, the stop block 105 can effectively limit the hook 202, that is, directly stop the displacement movement of the hook 202 away from the seat 104, thereby limiting the excessive deformation of the hook 202 and preventing the hook 202 from deforming and loosening due to the decrease of the elastic modulus of the material under high temperature environment, thus ensuring the stability and reliability of the connection structure between the sleeve 20 and the sun visor 10.

[0057] The following combination Figures 1-4 This application provides an embodiment of a vehicle sun visor sleeve connection structure, which includes:

[0058] At least one sleeve 20, one side of which has a through first channel 201 along the first direction x, and the other side has at least one hook 202;

[0059] The sun visor 10 has a second channel 101 along a first direction x, and a slot 102 for installing a sleeve 20 is provided along a second direction y corresponding to a portion of the path of the second channel 101. The first direction x and the second direction y are intersected. The sun visor 10 has a cavity 103 corresponding to the slot 102. The cavity 103 has an opening 1021 at the bottom of the slot 102 leading to the cavity 103. The cavity 103 has a stop block 105 and a card seat 104 corresponding to the hook 202, and there is a gap 1031 between the stop block 105 and the card seat 104.

[0060] The sleeve 20 moves along the second direction y towards the slot 102, the hook 202 passes through the opening 1021 and engages with the card seat 104 through the gap 1031, the first channel 201 communicates with the second channel 101; and the stop block 105 abuts against the hook 202, so that the stop block 105 stops the movement of the hook 202 away from the card seat 104.

[0061] During installation, the sleeve 20 moves along the second direction y towards the slot 102. Under the action of external force, the hook 202 passes through the opening 1021 and enters the cavity 103. When the hook 202 passes through the stop block 105 and the card seat 104 to form a gap 1031, the hook 202 contacts the card seat 104. The card seat 104 applies a directional force to the hook 202, causing the hook 202 to undergo adaptive elastic deformation, thereby allowing the hook 202 to pass smoothly through the gap 1031. Under the action of its own elastic restoring force, the hook 202 quickly resets and engages with the card seat 104. At the same time, the stop block 105 restricts the movement of the hook 202 away from the card seat 104 on the back side of the hook 202, effectively preventing the hook 202 from coming out, ensuring the stability of the connection after assembly, and preventing the sleeve 20 from coming out.

[0062] The aforementioned first direction x refers to the direction along the preset rotation axis of the sun visor. The sun visor 10 is rotatably connected to the roof beam or interior support above the vehicle (driver's seat, passenger seat) along the first direction x. By rotating the sun visor 10 around the first direction x, it blocks strong light from the front or sides, thereby meeting the shading needs during driving. This application does not limit the setting of the first direction x, and it can be set according to the vehicle's requirements. Typically, the first direction x can be set along the length or width of the sun visor 10, keeping it parallel to the side of the sun visor 10. This setting method is compatible with the body contour of the sun visor 10 and conventional processing technology, and the rotation structure can be positioned and processed directly based on the side of the sun visor 10, improving production efficiency. At the same time, it ensures that the movement trajectory of the sun visor 10 during rotation is regular, avoiding interference with surrounding components such as roof supports, rearview mirrors, and ambient lights, while allowing users to experience more even force and smoother movements during rotation. Of course, the first direction x can also form an angle with the length or width of the sun visor 10. It can be precisely adapted to the field of vision of the driver's seat and the curved shape of the roof interior. By optimizing the tilt angle of the rotation axis, the sun visor 10 can fit more closely with the roof interior when it is folded up, improving the aesthetics and integrity of the interior space, while not affecting the normal function of sun shading.

[0063] The aforementioned second direction y is an intersecting direction with the first direction x, used to provide an opening reference for the slot 102 of the second channel 101. Preferably, the first direction x and the second direction y are set perpendicularly. The perpendicularly distributed bidirectional layout allows for a clear spatial division between the rotation function of the sun visor 10 and the assembly function of the sleeve 20; at the same time, the vertical design facilitates dimensional positioning and tolerance control during the manufacturing process, and enables mass production of parts through standardized molds, reducing processing costs; moreover, the stop block 105 of the vertical structure provides a more direct and stable limiting effect on the hook 202, effectively resisting the risk of deformation and loosening under high temperature environments, further ensuring the reliability and durability of the connection structure between the sleeve 20 and the sun visor 10, taking into account both functional practicality and structural stability.

[0064] When the sleeve 20 moves along the second direction y toward the slot 102, its hook 202 passes through the corresponding opening 1021 and engages with the seat 104 of the sun visor 10 via the gap 1031. The first channel 201 on the sleeve 20 then connects with the second channel 101 on the sun visor 10, forming a through-channel structure for the support rod of the vehicle sun visor 10 to pass through. This application does not strictly limit the specific dimensional parameters (such as diameter, cross-sectional shape, length, etc.) of the first channel 201 and the second channel 101. It only needs to ensure that the through space formed after the two channels are connected can meet the requirements for the support rod to pass through, and that a suitable movable gap 1031 is left between the support rod and the inner wall of the channel after it is passed through. This ensures that the assembly and fixing of the support rod is not affected, and that the sun visor 10 can flexibly rotate around the first direction x with the support rod as the rotation reference, thereby effectively blocking strong light from the front or side above the driver's seat of the vehicle.

[0065] The number of hooks 202 can be flexibly adjusted according to actual assembly strength requirements, for example, one or more can be set to adapt to the usage scenarios and reliability requirements of sun visors 10 in different vehicle models. In some preferred embodiments, two hooks 202 are symmetrically provided on the sleeve 20. Correspondingly, the cavity 103 is provided with a locking seat 104 for each hook 202, and the two hooks 202 are symmetrically distributed along the second direction y. This symmetrical arrangement not only makes the engagement force between the hook 202 and the locking seat 104 more uniform, avoiding local deformation or loosening caused by concentrated force on a single hook 202, but also significantly improves the stability and load-bearing capacity of the connection structure between the sleeve 20 and the sun visor 10. The arrangement of the two hooks 202 can be outward V-shape, inward V-shape, or parallel to the second direction y, etc. See Figure 2 and Figure 4As shown, the preferred fabric is an outward V-shape (the free ends of the two hooks 202 open away from each other). This outward V-shape structure provides a natural guiding effect during the movement of the sleeve 20 along the second direction y-direction towards the slot 102 and the engagement process. The hooks 202 can slide against the side wall of the seat 104, guiding them precisely to the engagement position on the seat 104, effectively reducing alignment difficulty and improving assembly efficiency. Simultaneously, after the hooks 202 and seat 104 are fully engaged, the outward V-shape structure generates continuous lateral tension due to its elastic deformation, ensuring a tight fit between the hook 202's engagement surface and the seat 104, enhancing the anti-detachment effect of the engagement connection. The stop block 105 can be flexibly selected according to actual structural requirements. It can be configured in a one-to-one correspondence with each hook 202 (i.e., each hook 202 has a separate stop block 105 on its back side), further improving the anti-detachment stability of a single hook 202 through targeted limiting. See Figure 3 and Figure 4 As shown, a single stop block 105 can also be set in the middle area between the two hooks 202. The stop block 105 simultaneously limits the back side of the two hooks 202, restricting their movement away from the card seat 104. This design not only simplifies the structure and reduces processing costs, but also ensures that the two hooks 202 are subjected to balanced forces, avoids excessive deformation on one side, and further ensures the overall stability of the connection structure between the sleeve 20 and the sunshade 10.

[0066] The stop block 105 must be precisely positioned to match the relative distance between itself and the hook 202, ensuring that it effectively limits the hook 202. Simultaneously, it can provide auxiliary stopping for related components during assembly, preventing excessive deformation or displacement of the hook 202 away from the mounting base 104. (See also...) Figure 3 As shown, to further optimize the assembly effect and connection stability, it is preferable that the gap 1031 between the stop block 105 and the card holder 104 gradually decreases along the second direction y. Specifically, the side of the stop block 105 corresponding to the card holder 104 can be set as an inclined surface or an arc surface; so that the stop block 105 and the hook 202 form a close-fitting guide. Through the gradual gap 1031, the hook 202 is subjected to uniform lateral pressure during the assembly process, reducing assembly resistance and improving operational smoothness. At the same time, the side end of the stop block 105 can also form a tight abutment with the hook 202, preventing the hook 202 from falling out backward and enhancing the anti-disengagement effect of the snap-fit ​​connection.

[0067] The retainer 104 is used to engage with the hook 202. The shape of the retainer 104 can be customized as needed. It can have a groove (such as a U-shape or V-shape) or a slot, the opening 1021 of which is adapted to the engagement direction of the hook 202. After the hook 202 is engaged, the lateral restraint of the slot wall prevents it from falling off. See also Figure 3As shown, in some embodiments, the card holder 104 is strip-shaped, with one end of the card holder 104 near the opening 1021 fixed inside the cavity 103, and the other end suspended in a free state; see also Figure 5 As shown, the sleeve 20 moves along the second direction y towards the slot 102. Under the action of external force, the hook 202 passes through the opening 1021 and enters the cavity 103. When the hook 202 passes through the stop block 105 and the card seat 104 to form a gap 1031, the hook 202 abuts against the other end of the card seat 104. The card seat 104 applies a directional force to the hook 202, causing the hook 202 to undergo adaptive elastic deformation. At the same time, the other end of the card seat 104 also undergoes adaptive elastic deformation. The deformation (towards the side away from the stop block 105) allows the hook 202 to pass smoothly through the gap 1031. The other end of the hook 202 and the seat 104 quickly reset under their own elastic restoring force, so that the hook 202 and the other end of the seat 104 are engaged and connected. At the same time, the stop block 105 restricts the movement of the hook 202 away from the seat 104 on the back side of the hook 202, effectively preventing the hook 202 from coming out, ensuring the stability of the connection after assembly, and preventing the sleeve 20 from coming out.

[0068] When the hook 202 passes through the opening 1021 and engages with the seat 104 through the gap 1031, it is preferable that the engagement contact surfaces of the hook 202 and the seat 104 are completely fitted. That is, there is no local suspension or gap 1031 between the two, ensuring that they achieve surface contact engagement. The fully fitted engagement method maximizes the contact area between the hook 202 and the seat 104, effectively dispersing stress concentration at the engagement point, avoiding deformation and wear of the hook 202 or seat 104 due to excessive local stress during long-term use, and significantly improving the load-bearing capacity and durability of the connection structure; at the same time, the tightly fitted contact surfaces can increase the friction between the two, and with the limiting effect of the stop block 105, it can effectively resist the risk of loosening caused by vibration, bumps and vibration during vehicle operation and the decrease in the elastic modulus of the material under high temperature environment, ensuring the stability and reliability of the connection between the sleeve 20 and the sun visor 10.

[0069] See Figure 2 and Figure 4As shown, the sleeve 20 extends outward from the slot 102 with a connecting plate 203, and the outer surface of the sunshade 10 is provided with a relief groove 106 corresponding to the connecting plate 203. When the sleeve 20 moves along the second direction y, and the hook 202 passes through the opening 1021 and completes the engagement with the card seat 104 through the preset gap 1031, the connecting plate 203 is precisely embedded in the relief groove 106 of the sunshade 10, forming a fully fitted surface connection. The surface connection structure maximizes the contact area between the sleeve 20 and the sunshade 10, effectively dispersing the force on the assembly parts and improving the stability and load-bearing capacity of the overall connection structure. At the same time, the precise fit between the connecting plate 203 and the relief groove 106 can provide radial restraint for the sleeve 20, preventing the sleeve 20 from shifting or shaking during use. The connecting plate 203 can be designed as a split plate, that is, it extends into several independent plates corresponding to different edge positions or functional areas of the slot 102. The layout and size of each plate are adapted to the local structure of the slot 102 to ensure that it fits precisely with the corresponding area of ​​the relief groove 106 during assembly; or it can be designed as an integral structure, that is, the overall outline of the connecting plate 203 is completely adapted to the outer outline of the slot 102, and it extends in a continuous integral form, covering the corresponding outer area of ​​the slot 102.

[0070] The sun visor 10 described above can be integrally molded; or it can adopt a split assembly structure, formed by connecting the upper shell 107 and the lower shell 108 (see...). Figure 6 As shown in the figure, the sunshade 10 includes an upper shell 107 and a lower shell 108, which are connected to form a cavity 103.

[0071] The card holder 104 corresponds to the cavity 103 located on the upper shell 107 and / or the lower shell 108;

[0072] Alternatively, the stop block 105 may correspond to the cavity 103 located on the upper shell 107 and / or the lower shell 108.

[0073] The aforementioned card holder 104 corresponding to the cavity 103 being located on the upper shell 107 and / or lower shell 108 means that the card holder 104 can be located on the upper shell 107 corresponding to the cavity 103; it can also be located on the lower shell 108 corresponding to the cavity 103; or partial structures of the card holder 104 can be respectively provided on the upper shell 107 and lower shell 108, and when the upper shell 107 and lower shell 108 are connected, they are spliced ​​together to form a complete card holder 104. Similarly, the aforementioned stop block 105 corresponding to the cavity 103 being located on the upper shell 107 and / or lower shell 108 means that the stop block 105 can be located on the upper shell 107 corresponding to the cavity 103; it can also be located on the lower shell 108 corresponding to the cavity 103; or partial structures of the stop block 105 can be respectively provided on the upper shell 107 and lower shell 108, and when the upper shell 107 and lower shell 108 are connected, they are spliced ​​together to form a complete stop block 105.

[0074] The upper shell 107 and lower shell 108 can be fixedly connected by means of snap-fit, screw fastening, or ultrasonic welding, which are adapted to the assembly requirements of automotive interiors. There are no limitations on the shape and size of the upper shell 107 and lower shell 108. Preferably, the edge contours of the upper shell 107 and lower shell 108 match each other, giving the sun visor 10 a unified and complete visual effect, eliminating the abruptness caused by splicing marks, making the surface of the sun visor 10 smooth, and improving the overall aesthetics and refinement.

[0075] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
