Abstract
A safety protection device for a miniature truck comprises a motion servo-actuated apparatus positioned at a side of a cab of a miniature truck, and a brake apparatus positioned on a chassis of the miniature truck. The brake apparatus restricts movement of the servo-actuated apparatus. The servo-actuated apparatus is a safety hook that is fixedly arranged in an upward and vertical manner. The brake apparatus is equipped with a limiting rod above the safety hook. The brake apparatus restricts movement of the servo-actuated apparatus, and the movement of the cab, such as a great position change, can be limited through the chassis, so that accidents occurring in the cab are prevented.
Description
Technical field
The utility model is about a kind of safety guard of automobile, particularly for a kind of safety guard that min-truck is provided.
Background technology
Min-truck is the very competitive product of during China's automobile segments market, and it is taken into account and takes and transport double function, can meet the demand of many areas, Different crowds.And conduct high-end microcaloire moulding wherein, this vehicle main attack world market, the inclined to one side car of overall performance and moulding.
Therefore, in the travelling comfort of high-end min-truck, safety, also there is higher requirement.But the operator's compartment in existing dimension card is to be connected with chassis by wearing bolt in four elastic mounting points, and because rubber cushion rigidity is lower, traveling comfort is better.But, there is the risk that vehicle body is large at severe road conditions jerk value, existence rolls, overturns in the tendency that there will be upset, inclination when the braking of operator's compartment experience, turning operating mode.
Need to provide a kind of safety guard for microcaloire for this reason, in meeting traveling comfort, provide its safety performance.
Utility model content
For solving the problems of the technologies described above; the utility model provides a kind of min-truck safety guard; comprise: the motion follow-up mechanism and the brake equipment that is positioned at described min-truck chassis that are positioned at described cab of mini-type truck side; described brake equipment limits the motion of described follow-up mechanism; wherein said follow-up mechanism is by hard-wired safety hook vertically upward, and described brake equipment has the position-limited lever that is positioned at described safety hook top.
Brake equipment described in the utility model limits the motion of described follow-up mechanism, and, in the time that operator's compartment produces larger change in location, position-limited lever limits the motion of safety hook.This fender guard can limit by chassis the motion of operator's compartment, and for example larger change in location prevents the safety misadventure of operator's compartment.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Reference numeral: 1 operator's compartment, 2 chassis, 3 hook with safety tongs, 4 position-limited levers.
Detailed description of the invention
As shown in the figure; the utility model provides a kind of min-truck safety guard; wherein: comprise the motion follow-up mechanism that is positioned at described cab of mini-type truck 1 side and the brake equipment that is positioned at described min-truck chassis 2; described brake equipment limits the motion of described follow-up mechanism; wherein said follow-up mechanism is that described brake equipment has the position-limited lever 4 that is positioned at described safety hook 3 tops by hard-wired safety hook 3 vertically upward.
Described brake equipment in the utility model limits the motion of described follow-up mechanism, and, in the time that operator's compartment produces larger change in location, position-limited lever limits the motion of safety hook.Therefore fender guard can limit by chassis the motion of operator's compartment, and for example larger change in location prevents the safety misadventure of operator's compartment.
As optimization of the present utility model, the motion of described follow-up mechanism comprises beating, roll, overturn or coming off of operator's compartment.
As another prioritization scheme of the present utility model, between described brake equipment and described follow-up mechanism, there is Safety Redundancy gap.
As an improvement, the scope in described Safety Redundancy gap is 8～12 millimeters.
As the scheme of optimizing, in the time that described safety hook contacts with described position-limited lever, the acceleration/accel of described operator's compartment is 2.8～3.2g (g is acceleration due to gravity).
In preferred embodiment as shown in the figure, the utility model is mainly to realize restriction vehicle body jerk value object by the cooperation of safety hook and safety hook drag-line.
Operator's compartment safety hook is contained on body rear wall assembly by 4 M8 bolt combination parts respectively, and limit pull rod is welded on chassis.
Safety hook is formed by the welding of sheet metal parts hook-shaped, and limit pull rod is positioned at hook-shaped home position, in normally assembling situation, has 10.5mm gap between safety hook and limit pull rod.Calculating according to rubber cushion rigidity, can there is not rigidity contact in the vertical impact that can bear vehicle body 3g.
When vehicle body meets with the impact that exceedes 3g, operator's compartment is beated, and causing the gap between limit pull rod and safety hook is 0, and safety hook is realized rigidity contact in limit pull rod, and the trend of beating of operator's compartment is limited.Preventing that operator's compartment from continuing significantly to beat causes severe jolt or the danger that bolt fracture operator's compartment comes off occurs.
Because operator's compartment is to be connected with chassis by wearing bolt in four elastic mounting points, rubber cushion rigidity is lower, the tendency that operator's compartment there will be upset while meeting with braking, turning operating mode, rolls.In the rigidity contact of limit pull rod, can limit the tendency that rolls and overturn by safety hook.
Feature of the present utility model is mainly the jerk value that contacts to limit vehicle body by rigidity, the danger that inclination, upset, the vehicle body that prevents from causing because jerk value is excessive comes off.And leave safety gap, ensure that the normal jerk value of vehicle body is unaffected.
Should be appreciated that the claimed scope of the utility model is not limited to non-limiting embodiments, should be appreciated that non-limiting embodiments describes as just example.The protection domain of the essence that the application will require is more embodied in the scope that independent claims provide, with and dependent claims.
