[0002] A sealing strip structure is usually arranged between the door of an automobile and a door frame to prevent rainwater from entering the automobile. Since the sealing strip has a certain elastic deformation capacity, the sealing strip can provide a certain buffering effect for the door when the door is closed. However, the buffering effect is limited, and a large impact noise is generated when the door is slightly closed. SUMMARY

[0004] To achieve the above purpose, the application provides an automobile door panel spring bushing assembly, which comprises a spring sleeve and a spring seat. The spring sleeve comprises a corrugated telescopic pipe, one end of the corrugated telescopic pipe is connected with a pressure-bearing end which is adapted to contact one end of a spring, the spring seat comprises a connecting disc which is adapted to contact the other end of the spring, the end face of the connecting disc is provided with a limiting ring, the inner wall of the limiting ring is provided with a clamping ring groove, the other end of the corrugated telescopic pipe is connected with an embedded clamping ring which is adapted to be embedded in the clamping ring groove, so as to ensure the stable connection of the spring sleeve and the spring seat.

[0005] As a preferred, the inner bottom surface of the pressure-bearing end is provided with a first embedded handle which is adapted to be embedded in one end of the spring, the upper end surface of the connecting disc is provided with a second embedded handle which is adapted to be embedded in the other end of the spring, so as to limit the stability of the two ends of the spring body in the bushing assembly.

[0006] As a preferred, the end face of the second embedded handle is further provided with a through hole which communicates with the lower end face of the connecting disc, so as to allow air to pass through, balance the atmospheric pressure inside and outside the spring bushing assembly, and generate a damping effect by using the air flow resistance.

[0007] As a preferred, the part of the connecting disc outside the limiting ring is provided with a through hole, and a connecting member such as a bolt is arranged to pass through the through hole to fix the spring seat on a mounting seat in a door frame mounting groove.

[0008] As a preferred, the through hole has a plurality of through holes which are equidistantly arranged around the axis of the connecting disc, and the connecting member is used to uniformly constrain the connecting disc on the mounting seat of the door frame mounting groove.

[0009] As a preferred, a straight tube is further arranged between the corrugated telescopic pipe and the embedded clamping ring, the outer diameter of the embedded clamping ring is greater than the outer diameter of the straight tube, and the embedded clamping ring is matched with the clamping ring groove of the limiting ring.

[0010] As a preferred, the spring sleeve is of an integral structure and made of rubber material, having good flexibility.

[0011] As a preferred, the spring seat is of an integral structure and made of rubber or silica gel material, which can effectively prevent the spring from hard contact with the mounting seat of the door frame mounting groove.

DETAILED DESCRIPTION

[0021] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] like Figures 1-5 The automotive door panel spring bushing assembly shown includes a spring sleeve 1 and a spring seat 2 that can cooperate with each other. The spring sleeve 1 is an integral structure made of rubber material, which has good elasticity and toughness. The specific structure of the spring sleeve 1 includes a corrugated telescopic tube 102. By the extrusion deformation of the corrugated tube wall, the length of the corrugated telescopic tube 102 along the axis can be flexibly changed. One end of the corrugated telescopic tube 102 is connected to a pressure-bearing end 103, and its inner bottom surface will always be in contact with one end of the spring. The inner bottom surface of the pressure-bearing end 103 has a first inner insert shank 104, which is embedded in one end of the spring to ensure the contact position between the spring end and the pressure-bearing end 103.

[0026] The spring seat 2 is also an integral structure, made of rubber or silica gel material, directly in contact with the mounting seat in the mounting groove in the door frame, for avoiding the hard contact between the spring end and the door frame mounting seat, causing wear. The spring seat 2 includes a circular connecting disc 201 with a certain thickness, one end of which is used to contact the other end of the spring, so that the connecting disc 201 is separated between the spring and the hard door frame mounting seat. The upper end surface of the connecting disc 201 has a second embedded handle 202, which is embedded in the other end of the spring, to ensure the stable contact position of the other end of the spring with the connecting disc 201. The first embedded handle 104 and the second embedded handle 202 together limit the spring to be more likely to bear force along its own axis, so that the spring remains straight when it expands and contracts. The end surface of the second embedded handle 202 is also provided with a through hole 203 communicating with the lower end surface of the connecting disc 201, for balancing the internal and external air pressure of the spring sleeve 1. At the same time, since the air passing through the through hole 203 will be resisted, the spring bushing assembly also has a certain damping effect.

[0027] In order to stably connect the spring sleeve 1 and the spring seat 2, the end surface of the connecting disc 201 is provided with a coaxial limiting ring 205, and the inner wall of the limiting ring 205 is provided with a complete clamping ring groove 206. The other end of the corrugated expansion pipe 102 is connected with an embedded clamping ring 105. Actually, the corrugated expansion pipe 102 and the embedded clamping ring 105 also have a straight tube 101 therebetween. The straight tube 101 does not need to be stretched and deformed, so the wall thickness of the straight tube 101 can be greater than that of the corrugated expansion pipe 102, and the straight tube 101 can remain straight. The outer diameter of the embedded clamping ring 105 is greater than that of the straight tube 101, so the embedded clamping ring 105 can be embedded in the clamping ring groove 206, but by extruding the lower end of the straight tube 101, the embedded clamping ring 105 can be deformed and come out of the clamping ring groove 206.

[0028] The connecting disc 201 is provided with through holes 204 outside the limiting ring 205. The through holes 204 are several, equidistantly arranged around the axis of the connecting disc 201, for the bolts and other connecting members to pass through and fix the connecting disc 201 on the mounting seat in the mounting groove in the door frame. Since the spring seat 2 also limits the spring sleeve 1, the spring sleeve 1 and the spring seat 2 jointly constrain the spring body, so the spring and the spring bushing can be stably installed in the mounting groove reserved on the inside of the door frame.

[0029] Working principle: when installing, first put the coil spring into the spring sleeve 1, let one end of the spring sleeve in the first embedded handle 104, then let the other end of the spring top against the connecting disc 201, and sleeve in the second embedded handle 202, immediately extrude the straight cylinder tube 101 to make the embedded snap ring 105 shrink, and slide into the clamping ring groove 206 of the limiting ring 205 completely, after releasing the hand, due to the constraint of the limiting ring 205 to the embedded snap ring 105, even if there is the elastic force of the spring, the spring sleeve 1 will not separate from the spring seat 2, finally use the bolt and other connecting parts to pass through the through hole 204 of the connecting disc 201 and the threaded hole on the mounting seat in the inner side installation groove of the door frame to be screwed, and the installation and fixation can be completed;

[0030] When the door of the car is closed, the door plate will first hit the largest size pressure receiving end 103, and the pressure receiving end 103 will transmit the impact force to the spring body in the spring sleeve 1, and the coil spring will convert the kinetic energy conducted by the pressure receiving end 103 into its own elastic potential energy, at the same time, the corrugated expansion pipe 102 also absorbs part of the kinetic energy by shrinking, and the internal space of the spring sleeve 1 is reduced, the air at the bottom of the spring sleeve 1 is squeezed out from the convection hole 203, and due to the effect of air resistance, part of the kinetic energy is also converted into heat energy of air, thereby realizing the buffering effect of closing the door, and effectively reducing the impact noise of closing the door;

[0031] When the door lock of the car is opened, the coil spring and the corrugated expansion pipe 102 in the spring sleeve 1 release the elastic potential energy at the same time, and push the door away from the door frame, and only a small force is needed to open the door lock from inside the car or from outside the car, and the door will automatically pop open, of course, due to the damping effect of the spring bushing assembly, the opening speed of the door will not be very fast, and the person opening the door will not be hurt, and due to the resistance of the door hinge, the final opening degree of the door will not be very large, and the probability of increasing the door opening will not increase almost because of the setting of the spring bushing assembly.

[0032] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above examples, and the above examples and descriptions in the specification are only the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
