Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Referring to Fig.1~Fig. 4, a kind of suspension bicycle device, including double rocker mechanism and loaded on the connecting rod of double rocker mechanism On car locking mechanism, the driving lever of the double rocker mechanism provides torque by motor, and the double rocker mechanism is by two masters 2, two, the connecting rod follower lever 3, four of lever 1, two hinge stent 4 for fixing driving lever 1 and 3 one end of follower lever on the ground, Four straight pins for connecting each bar form;Car locking mechanism on the connecting rod loaded on double rocker mechanism is by one Park handlebar arm device, one park wheel assembly composition;The handlebar arm device of parking parks handlebar by two levels 5, two, the bracket shroud members covered on handlebar bracket, 6, two cylinders relatively-movable in sleeve and two are mounted in The horseshoe lock of latching handlebar on cylinder is constituted, and one of level parks the upper end of handlebar bracket Yu one of connecting rod Interference fit;The wheel assembly of parking parks 7, sleeve structures covered on wheel stand of wheel stand by a level The horseshoe lock 9 of part 8 and a latching wheel on sleeve is constituted, and the lower end of described two connecting rods is stopped with the level respectively Put the end interference fit of wheel stand.
Further, in the double rocker mechanism, driving lever and hinge stent pass through cylinder pin connection, wherein driving lever and cylinder Pin interference fit, hinge stent and straight pin transition fit.Connecting rod is connect with one end of the driving lever other end, follower lever, all with circle Pin transition fit.The other end and hinge stent of follower lever pass through cylinder pin connection, cooperation.
Connecting rod on double rocker mechanism is designed, the stop for meeting most model bicycles is allowed the device to. Device on connecting rod can allow people first to lock the bicycle on ground, make bicycle with the movement of four-bar mechanism after latching and Hanging movement, last four-bar mechanism are in stop after 180 degree in driving lever and link angle.Steps are as follows:
1. first lockking wheel with car locking wheel horseshoe lock first by bicycle parking in designated position;Level parks handlebar Bracket and covering can relatively rotate between the shroud member on handlebar bracket, shroud member and can between the cylinder in sleeve Horseshoe lock is carried out positioning crawl handlebar to realize by relative movement.
2. motor starts to start after to bicycle crawl, two be connected to motor driving lever is with equal angle speed Degree starts turning, while horizontal park handlebar bracket and cover can be passively opposite between the shroud member on handlebar bracket Rotation, shroud member and having between the cylinder in sleeve passively relatively move.
3. motor stops operating when detecting that driving lever and connecting rod angle are 180 degree, reach end-state.
A method of design four-bar mechanism hangs bicycle device:
(1) length for determining connecting rod is that a length is determined by the parameter of most of main holder for bicycle, so that the length Degree is the length of connecting rod b of double rocker mechanism.
(2) the rack length d of the condition small as far as possible based on parking space, double rocker mechanism is set as 1000mm.
(3) plane coordinate system, the intersection point of follower lever and connecting rod are established using follower lever and the intersection point of rack as coordinate origin For A point (x1, y1), the intersection point of driving lever and rack is C point (x2, 0), the angle of driving lever and rack is point α, follower lever and master The angle of lever is θ, as shown in Figure 2.Using the end-state of bicycle parking as model, the end-state is connecting rod and master The angle of lever is in 180 degree, i.e. angle α is equal to angle θ.The coordinate of the available point B of conditions above is (x1+ bcos α, y1- bsinα).Set up constraint condition and objective function.
Constraint condition are as follows:
1. to meet calculating surplus in engineering, when double rocker mechanism reaches the end-state of parking the rear-wheel of bicycle with The distance h on ground is more than or equal to 50 millimeters, i.e., to meet condition:
2. the size of angle α should not be too big, too big meeting is so that entirely mechanical device is unstable after parking;But α is also unsuitable It is too small, too small meeting so that after final parking bicycle horizontal projection can be larger.It integrates that is the size of angle α is answered In some section, we do the upper tangent line tangent with rear-wheel according to the handle of 24 cun of little Huang vehicle for the control, enable itself and water The angle of plane earth is θ0, with it come the size of about beam angle α: measurement measures above-mentioned angle theta0About 23 degree, because after parking certainly Driving is the whole and angled α in ground, and because our principle is that projected length of the bicycle on ground is most short, parking Angle θ afterwards0As far as possible at 90 degree or so, i.e., after final parking, -23 ° of angle α≤90 °=67 °.Because of the vehicle angle θ that we select0It is Bigger, so we design the constraint condition:
α≤72°
3. in order to guarantee that the transmission force property of double rocker mechanism is good, according to being referred in theory of mechanics [1] about most brief biography The requirement at dynamic angle, we have obtained the constraint condition required about this: γmin≥40°。
If the drive line angle of double rocker mechanism: just having started drive line angle is γmin1;Period can reach 90 degree of maximum value, then Continue to be decreased to γmin2.Constraint condition need to be met:
γmin=min { γmin1, γmin2}≥40°
Assuming that γmin2< γmin1, that is to say, that γminmin2.The verified establishment of condition assumed above.
Because of angle of the γ between connecting rod and follower lever, according to trianlgle geometry relationship, our available γ= 180 °-alpha-beta, thus obtain the identical constraint condition of meaning:
α+β≤140°
Objective function are as follows:
Bicycle projected length in the horizontal direction is most short when double rocker mechanism reaches the end-state of parking.Because if After angle α is determined bicycle projected length in the horizontal direction also it is thus determined that, and angle α is bigger, and projected length is shorter, so Objective function can make identical processing of angle α.That is:
Max=α
(4) the optimal active pole length a and driven pole length c that we want can be found out with Lingo programming.
