Abstract

The invention discloses an automobile seat height regulating mechanism, which comprises a shearing type mechanism, a spring, a mechanical locking device and a regulating handle, wherein the shearing type mechanism is provided with an upper support frame and a lower support frame; the spring is arranged between the lower part of the shearing type mechanism and the lower support frame; the spring can drive the upper support frame to upwards move and to ascend; when the upper support frame receives the downward force action, the tension of the spring can be overcome, so that the upper support frame downwards moves and descends; one end of the mechanical locking device is fixed on the upper support frame of the shearing type mechanism; one end of the mechanical locking device is fixed on the lower support frame; the locking is realized through the matching of pins and holes; the number of the pins is two; the number of the pin holes is two rows; the two rows of pin holes are arranged in a staggered way, so that the gear space is reduced by a half. The automobile seat height regulating mechanism has the advantages that the height regulating structure is simplified; the required position can be reached only through once regulation; the mechanical locking device uses the two pins and the two rows of holes; the gear space is reduced; the comfort performance is enhanced.

Description

A kind of automobile chair height guiding mechanism

Technical field

The present invention relates to automotive seat, particularly to a kind of automobile chair height guiding mechanism.

Background technology

Current commercial vehicle seat, in order to increase comfortableness, major part height joins seat configurations suspension system, and most suspension system is all containing scissor mechanism.

Current commercial vehicle seat, common height regulating mechanism has two big classes: 1) small rod mechanism, if shortcoming is to want to regulate to object height, need to regulate twice, regulate the height of front and rear respectively；2) integrated with suspension system, shortcoming is that cost is high.

Summary of the invention

It is an object of the invention to provide a kind of automobile chair height guiding mechanism.

The present invention includes scissor mechanism, spring, mechanical locking arrangement and adjustment handle, scissor mechanism is provided with upper bracket and lower carriage, between bottom and the lower carriage of scissor mechanism, spring is set, spring can drive upper bracket to move upward and raise, upper bracket forced downwards effect time, the pulling force of spring can be overcome, make upper bracket move downward and reduce；

Described mechanical locking arrangement is by upper mounted plate, lower locking plate, lock pin, return spring, shift fork and driving lever are constituted, upper mounted plate is fixed on upper bracket, lower locking plate is fixed on lower carriage, lock pin is arranged in upper mounted plate, lower locking plate has row's pin-and-hole, lock pin has baffle ring, lock pin is all arranged with return spring, return spring is between upper mounted plate and baffle ring, return spring promotes lock pin to be inserted in locking in the pin-and-hole of lower locking plate, driving lever is located in upper mounted plate, shift fork is fixed on driving lever, the plectrum of shift fork is inserted in the rear end of lock pin baffle ring, driving lever rotational drives shift fork to be extracted out from the pin-and-hole of lower locking plate by lock pin and release locking, regulate handle and be arranged on the outer end of driving lever.

In order to reduce gear spacing, not reducing intensity, described lock pin is two, and described pin-and-hole is two rows simultaneously, two row's pin-and-hole Heterogeneous Permutations, makes gear spacing reduce half.

The work process of the present invention is:

Seat declines and regulates: pull adjustment handle, rotating lever, driving lever drives shift fork to be displaced outwardly, shift fork is stirred lock pin and is deviate from from the pin-and-hole of lower locking plate, releases lockup state, and upper bracket is descending under the action of gravity of passenger, when going downwards to desired height, unclamping adjustment handle, lock pin inserts in pin-and-hole under the effect of return spring, and locks this height.

Seat rises and regulates: pull adjustment handle, rotating lever, driving lever drives shift fork to be displaced outwardly, shift fork is stirred lock pin and is deviate from from the pin-and-hole of lower locking plate, releases lockup state, and scissor mechanism drives upper bracket to rise under the action of the spring, when upper bracket rises to desired height, unclamping adjustment handle, lock pin inserts in pin-and-hole under the effect of return spring, and locks this height.

Beneficial effects of the present invention:

The present invention can be used on commercial vehicle seat.On the scissor mechanism basis of suspension system, increase mechanical locking arrangement.Advantage is, eliminates the structures such as air spring, antivibrator, control valve, trachea, simplifies system, reduce product cost；Utilizing the Holder for scissors of suspension system, frock general rate increases, experimental quantities reduces, and has not only decreased frock cost and checking cost, but also has reduced risk；Height of seat regulates simplicity, it is only necessary to regulates once, can arrive intended-location；This mechanical locking arrangement utilizes two pins, two rounds, reduces gear spacing, adds comfortableness.

Detailed description of the invention

Refer to shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present embodiment includes scissor mechanism 1, spring 2, mechanical locking arrangement 3 and regulates handle 4, scissor mechanism 1 is provided with upper bracket 5 and lower carriage 6, between bottom and the lower carriage 6 of scissor mechanism 1, spring 2 is set, spring 2 can drive upper bracket 5 to move upward and raise, upper bracket 5 forced downwards effect time, the pulling force of spring 2 can be overcome, make upper bracket 5 move downward and reduce；

nullRefer to Fig. 5、Shown in Fig. 6 and Fig. 7，Described mechanical locking arrangement 3 is by upper mounted plate 31、Lower locking plate 32、Lock pin 33、Return spring 34、Shift fork 35 and driving lever 36 are constituted，Upper mounted plate 31 is fixed on upper bracket 5，Lower locking plate 32 is fixed on lower carriage 6，Lock pin 33 is arranged in upper mounted plate 31，Lower locking plate 32 has row's pin-and-hole 37，Lock pin 33 has baffle ring 38，Lock pin 33 is all arranged with return spring 34，Return spring 34 is between upper mounted plate 31 and baffle ring 38，Return spring 34 promotes lock pin 33 to be inserted in locking in the pin-and-hole 37 of lower locking plate 32，Driving lever 36 is located in upper mounted plate 31，Shift fork 35 is fixed on driving lever 36，The plectrum of shift fork 35 is inserted in the rear end of lock pin 33 baffle ring 38，Driving lever 36 rotational drives shift fork 35 to be extracted out from the pin-and-hole 37 of lower locking plate 32 by lock pin 33 and release locking，Regulate handle 4 and be arranged on the outer end of driving lever 36.
