Embodiment
Carrying out the technical scheme that the present invention is described in detail by the following examples, following embodiment is only exemplary, only can be used for explaining and illustrating the technical scheme of the present invention, and can not be interpreted as being the restriction to technical solution of the present invention.
As shown in Figure 1, ergometer locating device forms primarily of two portions, and namely strut 2 and base 1 form, it may also be useful to time, ergometer is placed into the upper surface of base 1.
As shown in Figures 2 and 3, strut includes strut body 21, and strut body 21 is slab structure, and one end of strut body 21 is vertically bent to form bending portion 23, and bending portion 23 is provided with V-type opening 24; The pull bar (hook) of ergometer stretches out from the U-shaped opening 104 base 1, vehicle body or other fixtures withstand in V-type opening 24 place in bending portion 23, the part applying pulling force is needed to be connected with ergometer pull bar (hook) by the V-type opening 24 in bending portion or pull bar passes V-type opening 24 and is connected with part, pull ergometer base and ergometer, part can be applied pulling force.
Ergometer pull bar (hook) and need apply pulling force component can by this V-type opening 24, vehicle body or fixture can be withstood in this position when dynamometry simultaneously; Strut 2 afterbody has the chamfering of certain angle, is convenient to base 1 and its assembling; Strut 2 upper surface has a ratchet bar 22, under itself and base 1 positioned internal card 1071 acting in conjunction, it is possible to base 1 can rearwardly be moved, and to head movement, can not be mainly used in location base and prevent base from returning because of the effect of ergometer spring power.
As shown in Figures 4 to 7, base 1 includes upper bed-plate 101 and lower bottom base 102; The upper surface of upper bed-plate 101 is for placing ergometer, and the lower surface of upper bed-plate 101 is provided with convex groove 106, and the upper surface of lower bottom base 102 is provided with groove 1021; Convex groove 106 and groove 1021 are combined in convex hole; Strut body 21 wears hole in described convex, ensure that and the coordinating of strut 2. Why whole base is made up of upper bed-plate 101 and lower bottom base 102 two portions, mainly considers the assembling of the location control mechanism 107 of base inside.
As shown in Figure 5, it is provided with protuberance 103 upwards in one end of upper bed-plate 101, protuberance 103 is provided with U-shaped opening 104; The first sidewall at upper bed-plate 101 is provided with open holes near one end of protuberance, and open holes is connected with convex groove; Location control mechanism 107 also it is provided with near protuberance one end at convex groove 106; Location control mechanism 107 connects with the ratchet card on ratchet bar 22 and coordinates. The lower surface both sides of described upper bed-plate 101 are respectively provided with at least two and install groove 105, and in the present embodiment, the lower surface both sides of upper bed-plate 101 are respectively provided with two and install groove 105, are altogether four and install groove, so that the boss with lower bottom base assembles; It is inner that location control mechanism 107 is positioned at upper bed-plate 101.
As shown in Figure 7, its interior dimensions is identical with strut size for lower bottom base 102 structure, is convenient to and the coordinating of strut 2, and it has four boss 1022, installs grooves 105 with the four of upper bed-plate 101 and coordinates, and by screw, Up/down base connects into one overall.
As shown in Figure 8 and Figure 9, described location control mechanism 107 includes back position knob 1074, time position bar 1072, positioning cards 1071 and returns position torsion spring 1073; Described time position knob 1074 is structure as a whole with described time position bar 1072; Described time position bar 1072 is worn into described open holes, and time position torsion spring 1073 and positioning cards 1071 are installed on described time position bar 1072 successively; Position bar 1072 is an entirety with returning to return position knob 1074, returns position knob 1074 and is positioned on the right side of upper bed-plate, meets right-hand operated custom.
The surface that 2nd sidewall of described upper bed-plate 101 is relative with described open holes is provided with back position bar fixed orifices; Described returning in the bar fixed orifices of position is stretched in the end of described time position bar, can play the end to returning position bar like this and support, it is to increase the stability of location control mechanism.
The part passing described positioning cards 1071 on described time position bar 1072 is non-circular structure; Described positioning cards 1071 is worn into the described through hole 1075 of position bar 1072 that returns as non-circle; The area of described through hole 1075 is greater than the described cross-sectional area returning position bar and passing the part of described positioning cards. In the present embodiment, returning the part passing described positioning cards on the bar of position is waist type structure, it is waist type structure that positioning cards is worn into the described through hole returning position bar, main purpose prevents positioning cards and returns the relatively rotating of position bar, and can ensure that positioning cards follows back position bar rotation when rotating back to knob.
Wherein positioning cards is running fit with returning coordinating of position bar, as shown in Figure 9, when mainly considering that ergometer stretches, positioning cards can fluctuate up and down because of contacting the change of position with ratchet, the rotation of position knob is driven back to fluctuate, after adopting running fit, positioning cards and the gap returning position bar make the minor fluctuations of positioning cards can not cause back position bar and return the rotation of position knob, also can not produce bigger idle motion because of little gap when rotating back position knob on the contrary.
Described time position one end is butted on the bottom surface of described convex groove, and the other end is butted in described positioning cards; Under the effect of torsion spring, positioning cards remains and contacts with ratchet bar, blocks base, base can only be moved along a direction (ergometer draw direction), and all can not return because of the effect of ergometer spring power when moving to optional position. When rotating back to knob, positioning cards is rotated along with returning position bar, just can cancel and the contact of ratchet bar, now base just can bidirectional-movement, to unclamp ergometer, make ergometer go back to position.
The tolerance range when using ergometer and accessibility can be ensured, it is to increase the efficiency in vehicle trial-manufacturing process, simple and practical, adaptability is stronger, it is possible to be applicable to the ergometer of all kinds of stretching formula by the present invention.
Although it has been shown and described that embodiments of the invention, for the ordinary skill in the art, being appreciated that and these embodiments can be carried out multiple change, amendment, replacement and modification without departing from the principles and spirit of the present invention, the scope of the present invention is by claims and equivalent limits.
