Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to an intelligent adjustable support rod for automobiles. Background Technology
[0002] Automotive struts (such as hood struts and trunk struts) are used to support moving parts of a car, keeping them in the open position for easy access and maintenance. Traditional automotive struts are mostly hydraulic or spring-type. Hydraulic struts pose a risk of oil leakage and their support force is not adjustable; spring-type struts have a fixed support force and cannot adaptively adjust to different operating conditions (such as load changes or ambient temperature changes), resulting in insufficient convenience and reliability. Therefore, there is an urgent need for an automotive strut with adjustable support force, stable structure, and high adaptability. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an intelligent adjustable strut for automobiles. Through the coordinated action of the spring force balancing mechanism and the power transmission mechanism, the support force can be intelligently adjusted, thereby improving the adaptability and reliability of the strut.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent adjustable strut for automobiles, characterized in that: it includes a strut body, on which a front fixing mechanism, a spring force balancing mechanism, a power transmission mechanism, and a rear fixing mechanism are provided. The front fixing mechanism and the rear fixing mechanism are respectively disposed at both ends of the strut body. The spring force balancing mechanism includes a helical spring and a lead screw adjustment mechanism for adjusting its compression. The lead screw adjustment mechanism is connected to the power transmission mechanism, and the power transmission mechanism is used to drive the lead screw adjustment mechanism to reciprocate along the axial direction of the strut body.
[0005] Using the above technical solution, the front and rear fixing mechanisms are used to connect the strut body to the fixed and moving parts of the vehicle (such as the hood and body); the coil spring is used to provide basic support force and, in conjunction with the screw drive mechanism, adjust the force value; the power transmission mechanism is used to adjust...
[0006] The compression of the spring force balancing mechanism changes the supporting force.
[0007] The present invention is further configured such that: the lead screw adjustment mechanism includes a cylinder, a lead screw and a nut sleeve that is threadedly engaged with the lead screw; the nut sleeve is connected to the output end of the power transmission mechanism; one end of the helical spring abuts against the cylinder through a first connecting component, and the other end abuts against the front fixing mechanism through a second connecting component.
[0008] Using the above technical solution, the first connecting component and the second connecting member are used to axially limit the helical spring and ensure the stability of the spring force adjustment.
[0009] The present invention is further configured such that: the power transmission mechanism includes a power component and a reduction gear set, and the output shaft of the power component is connected to the nut sleeve through the reduction gear set.
[0010] By adopting the above technical solution, the power transmission mechanism is designed to provide stable driving force and achieve deceleration and torque increase, thereby ensuring the reliability of the screw drive.
[0011] The present invention is further configured such that: the strut body also includes a control module and a sensor, the sensor is used to detect the load on the moving parts of the vehicle or the force on the strut body, and the control module controls the action of the power transmission mechanism according to the detection signal of the sensor.
[0012] By adopting the above technical solution, this setup can achieve automatic adjustment of the support force, further enhancing the intelligence level of the strut.
[0013] The present invention is further configured such that both the front fixing mechanism and the rear fixing mechanism are ball joint structures.
[0014] Using the above technical solution, both the front and rear fixing mechanisms are set as ball joint structures. This design facilitates the adaptation to the angle changes of the moving parts of the car during the opening process and avoids the strut being subjected to additional bending moment.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. Adjustable support force: Through the cooperation of the screw drive mechanism and the power transmission mechanism, the compression of the spring force balancing mechanism can be precisely adjusted, thereby changing the support force of the strut to adapt to different loads and working conditions.
[0017] The structure is stable and reliable: the first connecting component and the second connecting component axially limit the spring force balancing mechanism to prevent the helical spring from shifting during adjustment and ensure the stability of force adjustment; the ball joint structure of the front fixing mechanism and the rear fixing mechanism can adapt to angle changes and reduce the wear of the support rod.
[0018] High level of intelligence: It works with control modules and sensors to automatically adjust the support force, improving ease of use and the overall intelligence level of the car. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Figure 1-3 shows an intelligent adjustable automotive strut, comprising a strut body 1. The strut body 1 has a front fixing mechanism 2, a spring force balancing mechanism, a power transmission mechanism 3, and a rear fixing mechanism 4. The front fixing mechanism 2 and the rear fixing mechanism 4 are respectively located at both ends of the strut body 1, and both are ball joint structures. The spring force balancing mechanism includes a coil spring 5 and a screw adjustment mechanism 6 for adjusting its compression. The screw adjustment mechanism 6 is connected to the power transmission mechanism 3, which drives the screw adjustment mechanism 6 to reciprocate along the axial direction of the strut body 1. The screw adjustment mechanism 6 includes a cylinder 61, a screw 62, and a nut sleeve 63 threaded with the screw. The nut sleeve 63 is connected to the output end of the power transmission mechanism 3. One end of the coil spring 5 abuts against the cylinder 61 through a first connecting component 7, and the other end abuts against the front fixing mechanism 2 through a second connecting component 8. The power transmission mechanism 3... It includes a power unit and a reduction gear set; the output shaft of the power unit is connected to the reduction gear set.
[0024] The strut body 1 is connected to the nut sleeve 63 and also includes a control module 9 and a sensor 10. The sensor 10 is used to detect the load on the moving parts of the vehicle or the force on the strut body. The control module 9 controls the action of the power transmission mechanism according to the detection signal of the sensor.
[0025] In this invention, the power component can preferably be a motor or electric motor. When it is necessary to adjust the supporting force of the strut, the motor or electric motor is started, and the nut sleeve 63 is rotated through the reduction gear set. The lead screw 62 moves axially, changing the compression of the helical spring 5. When the lead screw 62 moves towards the rear fixing mechanism, the compression of the helical spring 5 increases, and the supporting force increases (corresponding to the extended state of the strut, as shown in Figure 3). When the lead screw 62 moves towards the front fixing mechanism 2, the compression of the helical spring 5 decreases, and the supporting force decreases (corresponding to the shortened state of the strut, as shown in Figure 2).
[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
