Abstract
A poking block structure of a combined switch comprises a handle lever (1), a transmission lever (2) connected with the handle lever (1), a top pillar assembly and a gear block (5). The top pillar assembly is connected with the transmission lever (2) through a pressure spring (3); the top pillar assembly is contacted with the gear block (5); and the top pillar assembly comprises a body (4) connected with the pressure spring (3) and a rolling pillar (6) arranged on the body (4), and the rolling pillar (6) is in matching contact with a molded surface of the gear block (5). The poking block structure of the combined switch solves the problem of short service life due to damage caused by sliding friction between the top pillar and the gear block, prolongs service life, simultaneously enables poking of the handle lever to be smooth and improves customer satisfaction.
Description
Technical field
The utility model relates to a kind of unit switch structure, especially relates to a kind of unit switch block-dialing structure.
Background technology
Unit switch is the multifunction combined switch of controlling automotive lighting and light signalling device and some other annexes, and it is generally handle type, is installed on the steering column under the steering wheel, so that driver's operation; The unit switch block-dialing structure is realized the direct unit that multiple electrical equipment switches on and off on the automobile as the conversion of control gear and break-make, and the utilization in unit switch is extremely extensive.
Traditional automobile combined switch block-dialing structure, the sliding friction mode of gear conversion many employings fore-set and gear piece realizes, yet behind durability times arrival 10-12.5 ten thousand times, the wearing and tearing between fore-set and the gear piece will be more serious, affects the useful life of unit switch.Along with the development of automotive engineering and improving constantly of customer demand, the part main frame does not wait for ten thousand times the requirement of the automobile combined switch block-dialing structure durability times also corresponding 15-30 of being increased to, and obviously traditional sliding friction formula block-dialing structure is subjected to the constraint of himself structure to be difficult to satisfy this requirement.
The utility model content
The purpose of this utility model provides a kind of unit switch block-dialing structure, and the interior fore-set of solution unit switch and the sliding friction of gear piece are fragile, the problem that the unit switch life-span is short.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of unit switch block-dialing structure, comprise shell, handlebar, and with the drive link that handlebar joins, fore-set assembly and gear piece, fore-set assembly are connected stage clip with drive link and connect; The fore-set assembly contacts with the gear piece; Described fore-set assembly comprises the body that is connected with stage clip and the roller that is arranged on the body, and described roller contacts with the profile cooperation of gear piece.
Force of rolling friction when cooperating with the gear piece in order to reduce roller, the resistance to wear of enhancing roller and gear piece is provided with reference column on the shell, and the gear piece rotates around reference column; Described gear piece and roller-contact face are cancave cambered surface; The material of described gear piece is polyoxyethylene methylene, and the material of described roller is brass.
Preferably, described gear piece center line with drive link when initial condition is symmetrically arranged with two.
The beneficial effects of the utility model: contact with the cancave cambered surface rolling of gear piece by the roller on the fore-set assembly, mutual wearing and tearing have been reduced, prolong the useful life of unit switch, the resistance of simultaneously rolling friction is less, make stirring of unit switch handlebar more smooth and easy, improve customer satisfaction, described gear piece is symmetrically arranged with two with the center line of drive link, the stroke that handlebar is stirred up and down is identical, satisfy two circuit are controlled in, make things convenient for the layout of unit switch, satisfy the requirement of man-machine size.
Below with reference to drawings and Examples, the utility model is described in detail.
Description of drawings
Fig. 1 is perspective view of the present utility model.
Fig. 2 is the local enlarged diagram of block-dialing structure among Fig. 1.
Among the figure: 1. handlebar, 2. drive link, 3. stage clip, 4. body, 5. gear piece, 6. roller, 7. shell, 8. reference column.
Embodiment
Embodiment, shown in Fig. 1 to 2, a kind of unit switch block-dialing structure comprises shell 7, handlebar 1, with the drive link 2 that handlebar 1 joins, fore-set assembly and gear piece 5, fore-set assembly are connected with drive link by stage clip 3 connections; The fore-set assembly contacts with gear piece 5; Described fore-set assembly comprises the body 4 that is connected with stage clip 3 and the roller 6 that is arranged on the body 4, and described roller 6 contacts with the profile cooperation of gear piece 5.
Force of rolling friction when cooperating with gear piece 5 in order to reduce roller 6, the resistance to wear of enhancing roller 6 and gear piece 5 is provided with reference column 8 on the shell 7, and gear piece 5 rotates around reference column 8; Described gear piece 5 is cancave cambered surface with roller 6 contact-making surfaces; The material of described gear piece 5 is polyoxyethylene methylene, and the material of described roller 6 is brass; Preferably, described gear piece 5 center line with drive link 2 when initial condition is symmetrically arranged with two.
By pulling handlebar 1 motion, make handlebar 1 drive drive link 2 and move forwards or backwards, the fore-set assembly makes roller 6 move to corresponding gear along the cancave cambered surface of gear piece 5, thereby realizes the break-make of circuit under the effect of the stage clip 3 that joins with drive link 2; It is fragile with the sliding friction of gear piece that the utility model solves in the unit switch fore-set, and the problem that the unit switch life-span is short has prolonged useful life of unit switch, and the while has been improved customer satisfaction so that stirring of handlebar is more smooth and easy.
Claims (5)
