The camera module (1) of the present invention is provided with a tubular cover (19) and a lens holder (17). The cover (19) is fixed (bonded) to the substrate (11) with its legs (19a) in contact with the surface of the substrate (11). Moreover, the lens holder (17) is inserted into the inner surface (19b) of the cover (19), the lens holder (17) is in contact with the transparent plate (14) at its foot (17a) and its outer surface (17b) is in contact with the inner surface of the cover In the state, the outer surface (17b) of the lens holder (17) is fixed (bonded) on the inner surface (19b) of the cover (19). A lens (18) guiding the path of incident light to the light receiving portion (12a) of the imaging element (12) is fixed at a predetermined position on the lens holder (17).

A shifter is equipped with a rack and a stopper. A transmission gear transmits power from an electric motor to the rack. A retention pin extends vertically downward from the transmission gear. When the shifter slides to an origin, the retention pin locks the stopper, which causes the electric motor to step out. On detecting the step-out of the electric motor, the position control device recognizes that the shifter has reached the origin (the reference position) and has been fixed at the position, thus setting the shifter position.

The invention discloses a card lock. The problem that locks good in anti-theft function are not universal in the prior art is solved. The card lock comprises a lock body. The lock body comprises a lock inner container, a lock cylinder, locking pieces and a shifting piece, and the lock cylinder is arranged inside the lock inner container and provided with the shifting piece rotating along with the lock cylinder; the lock cylinder is sleeved with the locking pieces, so that the locking pieces and the lock cylinder rotate jointly; each locking piece is provided with an auxiliary key arm and a main key arm which extend towards the two sides of the locking piece to form lock inner container clamping pieces; a gap is reserved between the main key arm and the auxiliary key arm of each locking piece; the main key arms are elastic, so that the main key arms get close to the corresponding auxiliary key arms under action of external force; the main key arms are connected with key clamping pieces; the lock inner container is internally provided with lock inner container clamping grooves corresponding to the lock inner container clamping pieces in position; the lock cylinder sleeved with the locking pieces is arranged inside the lock inner container; the lock inner container clamping pieces of the main key arms of the locking pieces are clamped into the corresponding lock inner container clamping grooves. By means of the technical scheme, the problems in the prior art can be solved well.

The invention relates to the field of automobile equipment transportation, in particular to a transmission rail with guide wheels. The transmission rail comprises a support, bearing pedestals, rolling shafts, transmission shafts, guide plates and guide wheel mechanisms. The support is a rectangular frame; the two sides of the support are provided with the guide plates which are perpendicular to the plane of the support; the bearing pedestals which are arranged at equal intervals are arranged on the inner sides of the guide plates; two rolling shafts connected with one transmission shaft are arranged between every pair of bearing pedestals; the guide wheel mechanisms comprise the guide wheels, guide wheel discs, rolling wheels, bolts, nuts and guide wheel bases. The guide wheels are arranged at the upper ends of the guide wheel discs; the lower ends of the guide wheel discs are in contact with the guide wheel bases; one end of each bolt penetrates through a threaded hole in the corresponding guide plate to enter an inner cavity groove of the corresponding guide wheel base and is fixedly connected with the bottom of the corresponding guide wheel disc; the nuts are arranged at the other ends of the bolts to fix the bolts on the guide plates; the rolling wheels are arranged between each pair of guide wheel mechanisms. Due to arrangement of guide rails and the guide wheel mechanisms, the position of a transported part can be limited, the aim that the transported part does not fall off from the transmission rail is achieved, and therefore the transportation efficiency is improved.
