The invention discloses a motor relay capable of realizing contact quick closing. The motor relay comprises a driving mechanism, a push card, a moving spring component, a static spring component and a crank rocker mechanism. One end of the push card is matched with the moving spring component, and the other end is linked with the driving mechanism so as to drive the moving spring component to realize separating and closing of moving and static contacts through the push card when the driving mechanism operates. The crank rocker mechanism operates in a linkage way between the driving mechanism and the other end of the push card, and dead point position of the crank rocker mechanism is enabled to appear in the separating process of the moving and static contacts and the closing process of the moving and static contacts. The dead point position is arranged, and the idle stroke between the driving mechanism and the crank rocker mechanism is utilized so that the moving spring is enabled to get rid of the constraint of gear engaged transmission in the closing process to be quickly closed, the contacts are enabled to have sufficient dynamic pressure in closing by relying on the counter force of the moving spring or increasing torsion force provided by a torsional spring, and thus the objectives of quick closing of the contacts and instantaneous pressurization can be achieved.

The invention discloses an automobile oil tube connecting support and a riveting process thereof. The automobile oil tube connecting support comprises a support body and a polygonal oil tube connector matched with a hole position on the support wall of the support body, wherein a convex hull rivet at the hole position is pressed into an annular material clamping groove in the polygonal oil tube connector so as to increase pull force between the polygonal oil tube connector and the support body. In addition, the root portion of the side wall of the polygonal oil tube connector is extruded by using a riveting die to form a positioning protrusion so as to increase torsion between the polygonal oil tube connector and the support body. The automobile oil tube connecting support is simple in structure and capable of effectively ensuring the torsion and the pull force between the polygonal oil tube connector and the support body.

A roller blind assembly includes a blind roller, a clutch assembly that includes a bracket engagement member, and a pre-torsioned spring assembly that includes a spring. The pre-torsioned spring assembly is positioned in an interior cavity of the blind roller, and exerts a torque proportional to a preset torsion of the spring to promote rotation of the blind roller relative to the bracket engagement member. Rotation of the blind roller relative to the bracket engagement member in a first direction decreases torsion in the spring while rotation of the blind roller relative to the bracket engagement member in a second direction increases torsion in the spring. The pre-torsioned spring assembly is preferably selected from a group of at least two pre-torsioned spring assemblies, each spring assembly having a different spring preset torsion.

The invention relates to a spring type automatic frying pan, which comprises a pan body. A mixing rake used for mixing food is arranged in the pan body, a spring type power device used for driving the mixing rake to rotate is connected with the mixing rake and comprises a power spring, a transmission gear group, a limiting swing rod component and a fixed-speed swing component connected sequentially, the power spring is used for storing energy, the transmission gear group is used for transferring energy, the limiting swing rod component is used for limiting the rotating speed of the transmission gear group, the fixed-speed swing component is used for determining the swinging frequency of the limiting swing rod component, and the spring type power device is also provided with a rotating handle used for increasing torsion of the spring. By adopting the spring type power-driven frying pan, automatic mixing of food can be achieved via the mixing rake under conditions with no power supply, a user can conveniently rotate the power spring to store energy due to the rotating handle of the spring type power device, the energy in the power spring can be realized at a constant speed due to combination of the limiting swing rod component and the fixed-speed swing component, the automatic mixing time is extended, and more full and uniform food heating can be ensured.

The invention discloses an engine start control method. The engine start control method comprises the steps that zero clearing is conducted on control commands of a motor and a clutch, and the motor and the clutch are in an uncontrolled mode; a clutch combination command is sent, and a position state of the clutch is monitored; when the position state of the clutch is combination, a control mode of the motor is set as torque control; a torque value changing curve of the torque control is a given curve which comprises a period of eliminating gaps and a period of rapidly increasing torsion. According to the engine start control method, the cooperation of the motor and a single clutch is used to drive an engine, due to the fact that the torsion of the torque value changing curve of the motor increases slowly in the period of eliminating the gaps, mechanical impact force generated by driving the torque among the driving parts in a dynamical system is reduced, and the service life of the parts can be prolonged. In addition, by means of the engine start control method, due to the fact that the engine can be driven to the default rotating speed as soon as possible in the period of rapidly increasing the torsion, the start efficiency of the engine is improved.

A vehicle front end load bearing bolster is provided with improved structural performance and a lower component weight, while also minimizing material, tooling, and production costs. The front end assembly is formed with a hydro-formed cross car reinforcement tube secured or bonded with mechanical fasteners and room temperature adhesive to a bolster, thereby improving stress distribution and increasing cross car system stiffness. The bonded hydro-form tube / bolster assembly provides increased torsion stiffness and dimensional stability to the vehicle frame. The hydro-formed cross car reinforcement tube have flattened terminal ends with apertures for integrated attachment to a bolster. The hydro-formed cross car reinforcement tube is formed of aluminum, brass, carbon, steel, stainless steel, copper and high strength alloys. The bolster is formed of high strength plastics and composites including sheet molding compounds (SMC), bulk molding compounds (BMC), and thermoplastic compounds such as glass mat thermoplastic (GMT) and direct long fiber thermoplastic (DLFT).
