Description
Technical field
The present invention relates to a kind of auto parts machinery, particularly a kind of jump ring for installing vehicle lamp for lighting floor.
Background technique
Vehicle lamp for lighting floor is installed on the bottom of outside rear-view mirror housing, and this light plays illumination, the Security of reversing of getting on or off the bus to facilitate occupant, improve when parking at night or reversing.At present, light is generally directly fixed on the bottom of back-mirror housing by screw, fixing is poor, by the impact of automobile running vibration, the mounting screw of light easily produces to loosen and even comes off, light like this, light can shake when vehicle travels and produce abnormal sound, heavy then light can fall damage, and working life does not ensure.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of vehicle lamp for lighting floor that can make to install firm jump ring.
Technological scheme of the present invention is as follows: a kind of vehicle lamp for lighting floor jump ring, comprise jump ring body (1), described jump ring body (1) has straight perpendicular section (1d), the lower end of this perpendicular section (1d) is to side distortion bending, form the lower limit portion (1e) upwarped, upsloping segment (1c) is provided with in the top of described lower limit portion (1e), this upsloping segment (1c) and lower limit portion (1e) are positioned at the same side of perpendicular section (1d), the upper end of upsloping segment (1c) and the upper end of perpendicular section (1d) are connected as a single entity, the lower end of described upsloping segment (1c) first bends downwards towards the direction of perpendicular section (1d) is roundabout again, form changeover portion (1b) and upper limit portion (1a) from top to bottom successively, described upper limit portion (1a) is positioned at the oblique upper of lower limit portion (1e), form opening between the two.
Adopt above technological scheme, be provided with the mounting hole adapted with light shape size in the bottom of back-mirror housing, the side of mounting hole is provided with draw-in groove, and opposite side arranges fixed base, and fixed base is projecting inward to back-mirror housing, and offers hole clipping on fixed base; In light, the position of corresponding draw-in groove is provided with fixture block, and in light, the position of corresponding fixed base arranges fitting seat, and fitting seat is provided with restraining groove.Time light is installed, first the lower end of the present invention's section of erecting is snapped in the restraining groove of fitting seat together with lower limit portion, lower limit portion has the distortion towards perpendicular section direction, under the effect of its spring-back force, can clamp in fitting seat, then light is tilted, make the fitting seat end of light higher than fixture block end, and the fixture block in light is snapped in the draw-in groove of back-mirror housing, then light is set level, light is embedded in the mounting hole of back-mirror housing completely, and snaps in the hole clipping of back-mirror housing fixed base after upper limit portion of the present invention distortion.Under the effect of upper limit portion spring-back force, closely, fixing is good for upper limit portion and fixed base clamping on the one hand; On the other hand, after the opening compressive deformation that upper and lower limited part is formed, there is the trend expanded outwardly, and upper limit portion can not move by the constraint of fixed base, the spring-back force of such jump ring is applied in light towards the direction of fixture block, makes the fixture block of light together with the draw-in groove tight clamping fit of back-mirror housing.As can be seen here, the present invention not only self structure is simple, processing and fabricating is easy, and light can be facilitated to install, both made light easy accessibility, quick, and can guarantee that again light was connected with back-mirror housing firm, thus effectively prevent produce because of Vehicular vibration loosening or come off, while elimination abnormal sound, performance and the working life of light are ensured.
Angle a1 between described upper limit portion (1a) and changeover portion (1b) is 115-125 °, angle a2 between changeover portion (1b) and upsloping segment (1c) is 70-80 °, angle a3 between upsloping segment (1c) and perpendicular section (1d) is 40-50 °, and perpendicular angle a4 between section (1d) and lower limit portion (1e) is 25-35 °.Above structure, while being conducive to assembling, can provide lasting and stable elastic force by upper and lower limited part, to improve the fixing that light is installed further.
Preferred scheme is, angle a1 between described upper limit portion (1a) and changeover portion (1b) is 120 °, angle a2 between changeover portion (1b) and upsloping segment (1c) is 75 °, angle a3 between upsloping segment (1c) and perpendicular section (1d) is 45 °, and perpendicular angle a4 between section (1d) and lower limit portion (1e) is 30 °.
Concentrate in order to avoid stress and be damaged, between described upper limit portion (1a) and changeover portion (1b), between changeover portion (1b) and upsloping segment (1c), between upsloping segment (1c) and perpendicular section (1d) and between perpendicular section (1d) and lower limit portion (1e), all passing through arc transition.
Described upper limit portion (1a), changeover portion (1b), upsloping segment (1c), perpendicular section (1d) and lower limit portion (1e) are structure as a whole, and the steel sheet material bending being 0.8-1mm by thickness forms.Jump ring adopts steel integrative-structure, and selection is convenient, be easy to processing, and cost is low.The thickness of jump ring is advisable with 0.8-1mm, and thickness is too small, and the structural strength of jump ring is poor and the elastic force provided not enough, not only easily fractures after distortion, and can affect the fixing of light installation; Thickness is excessive, and jump ring distortion not easily, can increase the difficulty of assembling.
As preferably, the material of described upper limit portion (1a), changeover portion (1b), upsloping segment (1c), perpendicular section (1d) and lower limit portion (1e) is 65Mn spring steel.
Beneficial effect: the present invention can make light be installed on quickly and easily on back-mirror housing, and can guarantee that light installation is firm, can not by the impact of vehicle ride, both abnormal sound was eliminated, effectively prevent again and fall damage, there is the features such as structure is simple, processing and fabricating is easy, cost is low, all applicable on various types of automobile.
