In the present invention, unless otherwise specified, the use of the directional terms such as "up and down" generally refer to the positional relationship of the spring attachment structure when attached to the control arm.
The utility model provides a spring connecting structure of a control arm, which comprises a spring pad 1 capable of being connected to the control arm, wherein a groove 2 extending along the circumferential direction is formed in the periphery of the spring pad 1, and the groove 2 can accommodate a spring wire at the end part of a spring and limit the axial movement of the spring wire.
The spring in the scheme is a spiral spring, the spring wire of the main body part of the spring is of a spiral structure, the spring wire of the two ends can be of a coplanar annular structure, and the annular structure can be of an incomplete annular shape.
The spring connection structure of the present embodiment is used for connecting a spring to a control arm, wherein the spring pad 1 is a sheet structure with a certain thickness, the cross-sectional shape of the spring pad may be substantially circular, and a groove 2 extending along the circumferential direction is formed on the outer periphery of the spring pad, as shown in fig. 3, the spring wire 8 may be accommodated in the groove 2, so that the axial movement of the spring wire 8 (the axial direction refers to the axial direction of the spiral structure of the spring) may be limited by the groove 2, that is, the spring wire 8 is prevented from being separated from the spring pad 1, and the spring pad 1 may be connected with the control arm 9, for example, connected to the upper side of the control arm 9, so that the spring is stably held on the control arm 9, and the spring is prevented from swinging during transportation or lifting.
Wherein, the external diameter of the groove 2 gradually decreases and then gradually increases along the axial direction. Referring to fig. 2, the outer diameter of the spring pad 1 at the groove 2 is first decreased and then increased, so that the upper and lower sides of the groove 2 can block the spring wire 8 from moving axially. The cross section of the groove 2 is circular arc, and certainly, the bottom surface (or the side surface, the two are integrally connected) of the groove 2 can also be formed as a combination of a tapered conical surface and a tapered conical surface, or the cross section can be formed as a square, so that the function of limiting the axial movement of the spring wire 8 can be achieved.
Further, the minimum outer diameter of the groove 2 is smaller than or equal to the inner diameter of the spring wire, and the maximum outer diameter of the groove 2 is larger than the inner diameter of the spring wire. The inner diameter of the spring wire 8 is the inner diameter of an annular structure surrounded by the spring wire 8, the spring wire 8 can be accommodated in the position of the minimum outer diameter of the groove 2, the section of the spring wire 8 is circular, the section of the groove 2 can also be arc-shaped to better conform to the shape of the spring wire 8, and the maximum outer diameter of the spring wire is larger than the outer diameter of the spring wire 8, so that the spring wire 8 can be limited from moving axially.
Wherein, the spring cushion 1 comprises a rigid framework and an elastic part wrapping the rigid framework. The rigid frame may be made of metal or alloy, such as steel, copper, aluminum alloy, etc., the elastic part is outside the rigid frame, and the groove 2 is formed on the elastic part, i.e. the groove 2 is made of elastic material, so as to allow the groove 2 to deform to fit the spring wire 8 in the groove 2 or to disengage from the groove 2, and of course, the elastic part forming the groove 2 needs to be deformed when the spring wire 8 disengages from the groove 2. The rigid frame may allow the spring mattress 1 to maintain a certain shape to some extent, rather than being deformed without limitation, avoiding its excessive deformation and failing to function as a connecting spring, while the elastic portion may allow the spring mattress 1 to be more conveniently fitted with the spring wire 8.
Further, the elastic portion is made of rubber. The rubber may be attached to the rigid backbone by vulcanization. In other embodiments, the resilient portion may also be made of resilient silicone.
