TECHNICAL FIELD
[0001] The utility model relates to sunroof technical field especially relates to a double open sunroof. BACKGROUND
[0002] Most of the panoramic sunroofs of the existing automobile are designed by combining front and rear glass sunroofs, aiming to provide a more open view inside the vehicle and enhance the comfort of riding. The front glass sunroof is usually equipped with a precise mechanical driving mechanism, which enables it to realize various motion modes, including but not limited to lifting (i.e. lifting the front end upward by a certain angle to facilitate ventilation and reduce wind noise and rainwater intrusion) and translation (i.e. sliding open or closed horizontally to adjust the light and air circulation inside the vehicle). In contrast, the rear glass sunroof is usually designed as a fixed type without moving function, resulting in a smaller sunroof ventilation opening. SUMMARY
[0003] The utility model discloses a double open sunroof, which solves the problem of the smaller sunroof ventilation opening caused by the fixed design of the rear glass sunroof.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:
[0005] A double open sunroof, comprising a guide rail, a front sliding piece and a rear sliding piece are slidingly arranged on the guide rail, a front sunroof body is connected to the front sliding piece, a rear sunroof body is connected to the rear sliding piece, a push block is fixed to the rear end of the front sliding piece, a clamping block is rotatably connected to the front end of the rear sliding piece, a clamping groove is formed in the clamping block, a torsional spring is sleeved on the shaft rod of the clamping block, a lower protrusion is formed at the front end of the clamping block, and a fixed slot is formed in the guide rail for the lower protrusion to be clamped.
[0006] Preferably, a lower pressing surface is formed in the clamping block, one end of the torsional spring abuts against the lower pressing surface, and the other end of the torsional spring is inserted into the rear sliding piece.
[0007] Preferably, a guide inclined surface is formed on the rear side of the lower protrusion.
[0008] Preferably, a limiting block is fixed to the rear side of the rear sliding piece, and a blocking block is fixed to the guide rail to block the forward movement of the limiting block.
[0009] Preferably, a sliding groove is formed in the guide rail for the front sliding piece and the rear sliding piece to slide.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The movable rear sunroof body can enhance air convection in the vehicle, accelerate air circulation and improve ride comfort; compared with a fixed sunroof, the movable rear sunroof body has a larger opening range, improves brightness and vision in the vehicle, and can also serve as an additional escape exit in an emergency to increase safety.
[0012] In the mechanism of setting the push block and the clamping block to control the opening and closing of the sunroof, when the sunroof is in the opening process, the coordinated action of the push block and the clamping block not only pushes the clamping block to move backward, but also indirectly drives the rear sliding block to move backward, and this chain reaction significantly expands the opening range of the sunroof, and optimizes the ventilation and lighting effect in the vehicle. In the closing process, the push block pulls the clamping block forward, and the clamping block drives the rear sliding block to reset. This design ensures that the sunroof is closed smoothly and smoothly, and more importantly, when the rear sunroof body is about to return to the original position, the lower protrusion on the clamping block is cleverly clamped into the preset fixed slot, this step realizes the automatic separation of the clamping block and the push block, and then the front sliding part continues its forward movement, until the front sunroof body also accurately returns to the original position, and the movement of the rear sunroof body does not need additional power support.
