Abstract
The utility model discloses a stable low-noise seat driving part, which comprises a transmission case (200) and an end cover (300) arranged at an auxiliary transmission port (220) of the transmission case, wherein a screw rod (400) is arranged on the end cover, a worm wheel (500) for driving the screw rod to rotate is arranged on a transmission shaft (410) extending into the transmission case, and a unidirectional resistance spring (100) is arranged on an outer shaft end (411) of the transmission shaft; the one-way resistance spring is in an unsealed circular shape, one end of the one-way resistance spring is provided with an end head (110) which is warped outwards, so that one-way resistance of the one-way resistance spring is larger, the other-way resistance of the one-way resistance spring is smaller, and the end head which is warped outwards and arranged on the one-way resistance spring acts on the transmission case. The utility model discloses with the resistance of balanced seat doing two orientation motions upwards or downwards, reduce driving motor's speed difference, increase stationarity, noise reduction, and then solve inconsistent, the higher problem of noise of motor noise, improved the reliability of balanced resistance.
Description
Technical Field
The utility model relates to a seatpad driver part technical field.
Background
At present, when a motor drives a seat driving part to drive a seat to move upwards or downwards, if a load (such as the weight of a person) is added on the seat, the load is resistance when the seat moves upwards, and the load is assistance when the seat moves downwards, so that the speeds of the motor driving the seat driving part in two movement directions are inconsistent, the stability is poor, and further the noise decibel of the motor is inconsistent and the noise is high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve the inconsistent problem of speed, the noise of motor when current seat drive part drive seat is upwards or the downstream, and provide a steady low noise formula seat drive part to balanced seat is doing the resistance of upwards or two direction movements downwards.
The purpose of the utility model is realized through the following technical scheme: the stable low-noise seat driving component comprises a transmission case and an end cover arranged at an auxiliary transmission port of the transmission case, wherein a screw rod is arranged on the end cover, a worm wheel for driving the screw rod to rotate is arranged on a transmission shaft extending into the transmission case, and a unidirectional resistance spring is arranged at the outer shaft end of the transmission shaft; the one-way resistance spring is in an unsealed circular shape, one end of the one-way resistance spring is provided with an end head which is warped outwards, so that one-way resistance of the one-way resistance spring is larger, the other-way resistance of the one-way resistance spring is smaller, and the end head which is warped outwards on the one-way resistance spring acts on the transmission case.
Owing to adopted above-mentioned technical scheme, the utility model discloses a folk prescription has following advantage to the resistance spring: the one-way resistance spring has larger resistance in one direction and smaller resistance in the other direction, so that the resistance of the seat moving in the two directions of upward or downward can be balanced, the speed difference of a motor driving the seat driving part is reduced, the stability is improved, the noise is reduced, and the problems of inconsistent noise and higher noise of the motor are solved. The unidirectional resistance spring has simple structure, low cost and novel function. The unidirectional resistance spring is completely arranged in the transmission case, the appearance is not affected, the unidirectional resistance spring is sealed in the transmission case, the entering of dust and small particles is reduced, and the reliability of the balance resistance can be improved.

Fig. 2 is a schematic view of the installation structure of the unidirectional resistance spring of the present invention.
Fig. 3 is the assembly schematic diagram of the stable low-noise seat driving part of the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings and the detailed description.
Referring to fig. 1 to 3, the stable and low-noise seat driving component of the present invention includes a transmission case 200, and an end cap 300 installed at the auxiliary transmission port 220 of the transmission case 200, wherein a lead screw 400 is installed on the end cap 300, a worm gear 500 for driving the lead screw to rotate is installed on a transmission shaft 410 of the lead screw 400 extending into the transmission case 200, and a unidirectional resistance spring 100 is installed at an outer shaft end 411 (i.e., a left side of the worm gear) of the transmission shaft 410; the one-way resistance spring 100 is in an unclosed circular shape, one end of the one-way resistance spring 100 is provided with an end 110 which is warped outwards (the other end is in a common round dot shape), so that the one-way resistance spring 100 has a larger resistance in one direction and a smaller resistance in the other direction, and the end 110 which is warped outwards on the one-way resistance spring acts on the transmission case 200 (which is embedded in a bottom groove of the transmission case, as shown in fig. 2).
A motor is installed at the main transmission port 210 of the transmission case 200, and a worm is provided on an output shaft of the motor and connected to the worm wheel 500. The motor works to drive the worm wheel to rotate through the output shaft and the worm, so that the transmission shaft and the screw rod are driven to rotate. The transmission shaft 410 and the lead screw 400 can also be made into an integrated structure.
Claims (1)
1. Smooth low noise formula seat driver part, including transmission case (200), install end cover (300) at vice transmission port (220) of transmission case (200), its characterized in that: a screw rod (400) is arranged on the end cover (300), a worm wheel (500) for driving the screw rod to rotate is arranged on a transmission shaft (410) of the screw rod (400) extending into the transmission box (200), and a unidirectional resistance spring (100) is arranged on an outer shaft end (411) of the transmission shaft (410); the shape of the one-way resistance spring (100) is in an unsealed circular shape, one end of the one-way resistance spring (100) is provided with an end head (110) which is warped outwards, so that the resistance force of the one-way resistance spring (100) in one direction is larger, the resistance force of the other direction is smaller, and the end head (110) which is warped outwards on the one-way resistance spring acts on the transmission case (200).
