Abstract
The invention discloses a rotary support structure for sensors. The rotary support structure is installed on a rotary shaft of a Hall sensor. The rotary support structure is characterized by comprising a floating bar connector connected with a floating bar, a rotary shaft connector, and a fixing sleeve, wherein the rotary shaft connector connected with the rotary shaft is used for positioning and the fixing sleeve assists the rotary shaft connector in positioning. The floating bar connector is connected with the rotary shaft connector and is L shaped. The top and outside of the floating bar connector are provided with floating bar connecting channels. The rotary shaft connector is disposed on the inside of the floating bar connector and comprises positioning jaws which are mounted on two sides of the rotary shaft and which extend axially along the rotary shaft. Each positioning jaw is provided with an inner arc notch fitting the rotary shaft. The rotary shaft connector is sleeved with the fixing sleeve. The rotary support structure has the advantages that two-point positioning between the structure and the rotary shaft is changed into double-chamber fixation, the structure is more stable, and the service life of the structure is prolonged.
Description
Technical field
The present invention relates to a kind of rotary support structure that is applied to the Hall element on automotive oil tank, belong to the liquid level sensor technical field.
Background technology
On automotive oil tank, use for measuring the sensor of liquid level parameter, comparatively commonly used a kind of be Hall element.At present, the fixedly employing of the rotating shaft of Hall element is at the bilaterally symmetric anchor point that is provided with of axle, and at the link position of fly rod and rotating shaft also away from anchor point, this just makes as the activation point of the fly rod of driving stem away from as the position of the anchor point as stationary installation, so cause certain deviation in the process of rotating shaft deflection, make measuring accuracy accurate not.And, due to the needs of this structural design, rotating shaft is longer, the torsion strength that rotating shaft itself is born just descends, and affects the serviceable life of Hall element.
Summary of the invention
For the measuring accuracy that improves Hall element and extend its serviceable life, the invention provides a kind of sensor rotation supporting construction.
Purpose of the present invention is carried out specific implementation by the following technical programs:
The sensor rotation supporting construction, be arranged in the rotating shaft of Hall element, the fixed cover that the rotating shaft web member that comprises the fly rod web member that is connected with fly rod, is connected with rotating shaft and locates, auxiliary rotating shaft web member position, described fly rod web member is connected with the rotating shaft web member, preferably, described fly rod web member and rotating shaft web member are one-body molded; Described fly rod web member is L-shaped, at end face and the lateral surface of fly rod web member, is respectively equipped with the fly rod link slot, and described fly rod link slot is open architecture, and the inwall of fly rod link slot is cylindrical; Described rotating shaft web member is positioned at the medial surface of described fly rod web member, described rotating shaft web member comprises and is arranged on the rotating shaft both sides and along the axially extended locating detent of rotating shaft, the inside of each locating detent has the arc notch matched with rotating shaft, the both sides of locating detent respectively are provided with two positioning tooths parallel with locating detent, between two positioning tooths of every side, a magnetic sheet is installed, described fixed cover is socketed in the outside of rotating shaft web member, and fixed cover is fixed the magnetic sheet between locating detent, positioning tooth and positioning tooth.
The sensor rotation supporting construction designed by the present invention, make location between itself and rotating shaft become two arc surfaces by the two point location and fix, and makes its structure more stable, and can increase the service life.
