Description

Technical Field

[0001] This utility model relates to the technical field of automotive sunroofs, and in particular to a structure for preventing the flexible hose from detaching from an automotive sunroof. Background Technology

[0002] The flexible shaft (usually a steel wire flexible shaft) of an automotive sunroof connects the sunroof motor to the mechanical structure, transmitting the motor's rotational power to the sunroof track mechanism to enable the sunroof's sliding and tilting movements. With increasing demands for quiet operation, the traditional structure where the flexible shaft directly passes through the mounting beam and into the connector hole produces significant noise. More and more sunroofs are adopting a method where a flexible tube is first inserted into the connector hole before the flexible shaft is threaded through to reduce noise. However, because the flexible shaft diameter remains constant, inserting the flexible tube into the connector hole increases the outer diameter of the hole, causing interference with the motor. This necessitates cutting away the interference area from the connector hole. This leaves a large gap in the cut area, typically around 5.5mm, while the flexible tube diameter is generally 7.2mm. Even then, if the sunroof stalls during operation, the flexible tube can still be forced out of the connector hole by the flexible shaft, causing the sunroof to malfunction. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a structure to prevent the flexible hose from coming loose in a car sunroof. It has a simple structure, can hold the hose in place, prevent the hose from coming loose from the insertion hole, and effectively prevent the risk of the hose coming loose when it is under force and stuck.

[0004] The technical solution adopted by this utility model is: a structure for preventing the flexible hose from detaching from a car sunroof, including a plastic beam body. The plastic beam body has a positioning area for fixing a motor. The plastic beam body has a mating hole for positioning the flexible hose. A positioning block is provided on the side of the mating hole away from the positioning area. The positioning block has a through hole for the flexible hose to pass through. The bottom of the mating hole has multiple lower anti-detachment covers for supporting the flexible hose. The lower anti-detachment covers have a first limiting groove that matches the outer contour of the flexible hose. The upper part of the mating hole has multiple upper anti-detachment covers. The bottom of each upper anti-detachment cover has a second limiting groove that matches the outer contour of the flexible hose. A limiting channel for limiting the flexible hose is formed between the anti-detachment covers and the lower anti-detachment covers.

[0005] Preferably, the gap width between the front end of the lower anti-detachment cap and the side wall of the insertion hole, and the gap width between the front end of the upper anti-detachment cap and the side wall of the insertion hole are both less than one-third of the diameter of the hose.

[0006] Preferably, the plurality of lower anti-detachment covers and the plurality of upper anti-detachment covers are alternately arranged.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0018] like Figures 1-3As shown, this embodiment provides a structure to prevent the flexible hose from detaching from a car sunroof. It includes a plastic beam body 1, a positioning area 2 for fixing the motor, and a mating hole 4 for positioning the flexible hose 3. A positioning block 5 is located on the side of the mating hole 4 away from the positioning area, and a through hole 6 for the flexible hose 3 to pass through. The above describes the structure of existing plastic beams. However, the flexible hose has a relatively large gap exposed in the area where the mating hole is cut off, typically around 5.5mm. The hose diameter is generally 7.2mm. Even with this gap, if the engine stalls during operation, the flexible hose can still be squeezed out of the mating hole by the flexible shaft, causing the sunroof to malfunction.

[0019] This application has made improvements to this, such as Figure 2 As shown, multiple lower anti-detachment covers 7 are provided at the bottom of the insertion hole 4 to support the flexible hose 3. Each lower anti-detachment cover 7 has a first limiting groove 8 that matches the outer contour of the flexible hose 3. Multiple upper anti-detachment covers 9 are provided at the top of the insertion hole 4. Each upper anti-detachment cover 9 has a second limiting groove 10 at its bottom that matches the outer contour of the flexible hose 3. A limiting channel is formed between the anti-detachment covers 9 and the lower anti-detachment covers 7 to limit the flexible hose 3. The upper and lower anti-detachment covers 9 and 7, equidistantly arranged in the vertical direction of the insertion hole 4 to secure the flexible hose 3, prevent the Y-axis length of the large gap from being too long, reduce the gap of the opening, and secure the flexible hose 3 to prevent it from detaching from the insertion hole 4 during operation and engine stalling. Furthermore, this invention has a simple structure and solves the risk of the flexible hose 3 protruding from the insertion hole 4 when the sunroof stalls.

[0020] like Figure 3 As shown, the gap width between the front end of the lower anti-disengagement cover 7 and the side wall of the interlocking hole 4, and the gap width between the front end of the upper anti-disengagement cover 9 and the side wall of the interlocking hole 4 are both less than one-third of the diameter length of the hose. This prevents the Y-direction length of the larger gap from being too long, reduces the gap of the opening, and secures the hose to prevent it from coming off the interlocking hole when the hose is stuck during operation.

[0021] In sunroofs with flexible hoses of the same type, avoiding the motor interference position will result in a larger opening size to be avoided. Under harsh conditions, the temperature will affect the change in the elasticity of the hose, and the hardness of the hose itself also needs to be strictly controlled. The stalling force generated by the sunroof's flexible shaft during operation may cause the hose to protrude outside the insertion hole, leading to sunroof failure.

[0022] The lower anti-detachment cover 7 and multiple upper anti-detachment covers 9 are all provided with reinforcing ribs 13 on their back sides, which provides strong connection strength and is not easily deformed, thus providing a better buckling effect for the hose. This utility model is a structure for preventing the hose from detaching from a car sunroof: even when the temperature reaches 90℃, this structure still holds the hose in place, preventing the hose from detaching from the insertion hole, effectively preventing the risk of the hose detaching when under pressure and stuck. This structure is designed on the insertion hole and has a simple insertion mold.

[0023] Multiple lower anti-detachment covers 7 and multiple upper anti-detachment covers 9 are arranged alternately. With the alternating arrangement of the lower anti-detachment covers 7 and the upper anti-detachment covers 9, the hose has a better anti-detachment effect, and less plastic is injected, thus saving raw materials.

[0024] The upper anti-detachment cover 9 and the lower anti-detachment cover 7 are integrally injection molded with the plastic beam body 1, which makes them easy to manufacture.

[0025] The inner side of the positioning block 5 is provided with a support block 11 that mates with the insertion hole 4 and is used to support the hose 3. The support block 11 is provided with an arc groove 12, which serves to support the hose and prevent the waterproof hose from being suspended.

[0026] The innermost upper anti-detachment cover 9 is close to the positioning area 2, which has a good limiting and anti-detachment effect on the connection between the hose and the motor.

[0027] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
