Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile parts, and specifically relates to a storable hidden roof luggage rack. BACKGROUND

[0002] The roof luggage rack is mainly used for expanding the load space, but the traditional scheme is mostly fixed or detachable metal support. In recent years, the improvement direction includes: hidden slide rail design: the roof is pre-buried with slide rails, and the support needs to be manually installed when being externally hung (such as Audi A6 Allroad); electric lifting luggage rack: the support is lifted from the roof through a motor (patent CN112298233A), but the structure is complex and the storage space is limited; flexible storage scheme: soft material is used for folding storage (such as inflatable luggage rack), but the bearing capacity is poor. The closest scheme: patent CN110588763A proposes a "hidden roof luggage rack", which realizes storage through slide rails and liftable supports. The core is that the roof is pre-buried with slide rails, and the support is lifted vertically through a motor. However, the following problems exist: the lifting mechanism occupies the internal space of the roof, affecting the rigidity of the roof; only vertical lifting is supported, which cannot adapt to different sizes of articles; there is no automatic locking mechanism, and the support is easy to shake on a bumpy road.

[0003] Existing technology defects: storage and function contradiction: the hidden design needs to sacrifice the internal space of the roof, reducing the structural strength of the vehicle body; insufficient adjustment flexibility: the vertically lifting support cannot adapt to different load requirements (such as long strip-shaped articles that need to expand the support length); safety risk: the traditional locking mechanism relies on manual operation, and the support may be accidentally ejected during driving; high maintenance cost: the exposed slide rails are easy to accumulate dust or freeze, and the lifting is stuck. UTILITY MODEL CONTENTS

[0004] The utility model provides a full-automatic hidden roof luggage rack to solve the above problems, which can be completely embedded in the roof during storage without damaging the streamline of the vehicle body; the support length can be expanded to adapt to different load scenarios; the support is automatically locked during driving to avoid accidental expansion; no internal space of the roof is needed, and the support is directly integrated into the vehicle body longitudinal beam. The specific technical scheme is as follows:

[0005] The application discloses a stowable and hidden roof luggage rack, which comprises a bidirectional slide rail system, a folding support, a driving and locking module and a control unit, the control unit is integrated in a general control console of a vehicle, and is in communication connection with the bidirectional slide rail system, the folding support and the driving and locking module; the bidirectional slide rail system is arranged in longitudinal beams on both sides of the roof in a built-in mode, and a waterproof sealing strip is arranged on the surface of the slide rail; the folding support is arranged in the slide rail, the folding support is connected by three-section hinges, is folded and pasted in the slide rail in a stowed state, is straightened and locked by a gear and a rack mechanism in an unfolded state; the driving and locking module comprises a driving part and a locking part, the driving part is a micro stepping motor driving gear set, and drives the support to move along the slide rail; the locking part is double-secured by an electromagnetic bolt and a mechanical ratchet, and is automatically locked when the vehicle speed is greater than 5km / h or the acceleration is greater than 0.5g.

[0006] Further, the control unit obtains a vehicle speed signal through a vehicle body CAN bus, and supports unfolding or stowing through a mobile phone APP or an in-vehicle button.

[0007] Further, the slide rail opening of the bidirectional slide rail system is provided with a silica gel scraping piece and an air pressure balance valve to prevent water from entering or icing.

[0008] The working strategy of the utility model can adopt: a user APP sends an "unfolding" instruction, the control unit detects that the vehicle speed is 0, then the motor is started, and the support slides out along the slide rail; when the support slides out to a set position, such as 80% of the full length, the hinge section is automatically straightened, and the electromagnetic bolt is locked; after the object is carried, the APP triggers "stowing", the support is folded and retracted into the slide rail, and the sealing strip is closed.

[0009] The slide rail and the vehicle body longitudinal beam are integrated, the slide rail is directly embedded in the inside of the longitudinal beam, and simultaneously serves as a vehicle body structure reinforcing piece; dynamic locking can be realized, that is, when the vehicle speed is greater than 5km / h or the acceleration is greater than 0.5g, the electromagnetic bolt is forcibly locked; and the waterproof design is also provided, the silica gel scraping piece and the air pressure balance valve are adopted at the slide rail opening to prevent water from entering or icing.
