The upper housing 110 may include a projection 111 provided on an upper surface thereof. The protrusions 111 may be provided in a pair. The protrusion 111 can be fitted into a hole (not shown) provided in the trunk 101. The upper housing 110 can be coupled to the trunk 101 by engaging the projection 111 in a hole (not shown). At this time, since no separate fastening member is required for coupling the upper housing 110 and the trunk 101, the installation of the oversam bumper 100 is simplified and the production cost is reduced.

An insertion groove 112 may be formed on the lower surface of the upper housing 110. The insertion groove 112 may be formed by recessing the lower surface of the upper housing 110 inward.

The upper housing 110 may include a rib 114 extending downwardly along the periphery of the insertion groove 112 on a lower surface thereof. A male screw thread 115 may be provided on the outer circumferential surface of the rib 114.

The bumper 150 may include a shock absorbing portion 154 for absorbing impact and a protruding portion 151 protruding upward from the upper surface 154a of the shock absorbing portion 154. [

The buffer 154 may be made of a rubber material so as to absorb shock. The buffer part 154 comes into contact with the vehicle body 102 when the trunk 101 is closed. As described above, since the buffer part 154 can be made of a rubber material, the shock applied to the body 102 can be absorbed.

The bumper 150 may include a second coupling groove 152 formed on the upper surface of the protrusion 151 and the upper surface 154a of the buffer part 154. [ The second coupling groove 152 may be formed in a substantially straight line when viewed from the upper surface of the bumper 150. This is to match the cross-sectional shape of the elastic member 140 because the cross section of the elastic member 140 to be described later has a linear shape.

The protrusion 151 may have a substantially cylindrical shape. A male screw thread 153 may be provided on the outer circumferential surface of the protrusion 151. This is for screw connection with the female threads 131 provided on the inner circumferential surface of the top cover 130.

Meanwhile, the bumper 150 may be provided by a double injection method. The protruding portion 151 must be made of a soft material such as rubber because it must absorb the impact while the protruding portion 151 includes a male thread and is to be coupled with the top cover 130 through the male thread. Because. That is, since the material of the projection 151 and the buffer 154 must be different from each other, a dual injection method capable of satisfying such a requirement in manufacturing the bumper 150 can be used.

The oversam bumper 100 may include an elastic member 140 adapted to provide an elastic force to the bumper 150.

The elastic member 140 may include a torsion spring. That is, a part of the elastic member 140 can be rotated by applying an external force to the elastic member 140, and if the external force is not applied, the elastic member 140 returns to its original shape.

The elastic member 140 includes a fixed end 141 provided at both ends of the elastic member 140 and a rotation end 142 provided between the fixed end 141 and the fixed end 141 and the rotation end 142 (Not shown). The fixed end 141 can be coupled to the first engagement groove 113 of the upper housing 110 and the rotation end 142 can be coupled to the second engagement recess 152 of the bumper 150. The connection portion 143 may form the rotation axis R of the bumper 150. Details of this will be described later.

The oversam bumper 150 may include a top cover 130 adapted to engage the bumper 150. A female screw thread 131 may be formed on the inner circumferential surface of the top cover 130. The top cover 130 and the projection 151 of the bumper 150 can be screwed together. The elastic member 140 coupled to the bumper 150 can be prevented from separating from the bumper 150 when the top cover 130 is engaged with the bumper 150. [

Hereinafter, a method of assembling the oversam bumper 150 according to the embodiment of the present invention will be described in detail.

As shown in FIG. 5, the elastic member 140 may be coupled to the upper portion of the bumper 150. The rotation end 142 of the elastic member 140 and a part of the connection portion 143 can be fitted into the second engagement groove 152 provided on the upper surface of the bumper 150. [ Since the elastic member 140 is not fixed to the bumper 150 by inserting the elastic member 140 into the second engagement groove 152, the top cover 130 can be coupled to the bumper 150 .

As described above, the female thread 131 is formed on the inner circumferential surface of the top cover 130, and the male thread 153 is formed on the outer circumferential surface of the protruding portion 151. The elastic member 140 can be prevented from deviating to the upper side of the bumper 150 by screwing the top cover 130 and the protrusion 151 after the elastic member 140 is inserted into the second engagement groove . At this time, there is no need for a separate fastening member for coupling the top cover 130 and the bumper 150, which is advantageous in that the assembly is simple.

As shown in FIG. 6, an insertion groove 112 and a first coupling groove 113 may be formed on the lower surface of the upper housing 110. A rib 114 protruding downward may be provided on a lower surface of the upper housing 110 and a male screw thread 115 may be formed on an outer circumferential surface of the rib 114.

The bumper 150 to which the top cover 130 and the elastic member 140 are coupled can be inserted into the insertion groove 112 of the upper housing 110. At this time, the fixed end 141 of the elastic member 140 should be inserted into the first engagement groove 113. The lower housing 120 can be coupled to the upper housing 110 after the fixed end 141 is inserted into the first coupling groove 113. [ Since the female thread 121 is provided on the inner circumferential surface of the lower housing 120, the lower housing 120 can be screwed to the rib 114. The elastic member 140 and the top cover 130 and the bumper 150 are prevented from falling to the lower side of the upper housing 110 by the engagement of the upper housing 110 and the lower housing 120. [

The oversam bumper 150 according to the embodiment of the present invention can be assembled through the above process. In this case, there is an advantage that the assembly is simple since there is no fastening process using a separate fastening member.

7 is a cross-sectional view of the oversam bumper taken along the line A-A 'in FIG. FIG. 8 is a view showing an oversam bumper according to an embodiment of the present invention when the oversam bumper is not in contact with a counterpart, and FIG. 9 is a cross- FIG. 10 is a view showing a state in which an oversam bumper according to an embodiment of the present invention is rotated in contact with a mating part. Referring to FIG.

Hereinafter, the rotation operation of the oversam bumper 150 according to the embodiment of the present invention will be described in detail.

7, the connecting portion 143 of the elastic member 140 may form the rotation axis R of the bumper 150. [ That is, the bumper 150 can rotate about the connecting portion 143. However, an elastic member provided with a torsion spring can prevent the bumper 150 from rotating. That is, unless an external force that is stronger than the elastic force of the elastic member 140 is applied, the bumper 150 does not rotate and applies an external force stronger than the elastic force of the elastic member 140 so that even if the bumper 150 rotates, The bumper 150 returns to its original position.

The bumper 150 is in place before or after the oversam bumper 150 mounted on the opening and closing apparatus 101 contacts the vehicle body 102 as shown in Fig. 9 and 10, when the bumper 150 comes into contact with the main body 102 when the opening and closing device 101 is closed, the bumper 150 can rotate about the rotation axis R. [ When the opening / closing device 101 is opened, the bumper 150 can be rotated and returned to its original position as shown in FIG.

The oversam bumper 100 is rotated to increase the contact area between the bottom surface 155 of the bumper 150 and the main body 102. That is, as shown in FIG. 10, when the oversam bumper 150 is in surface contact with the main body 102, the bumper 150 does not rotate. 9, when the oversam bumper 150 is in line contact with the main body 102, the bumper 150 is rotated (rotated) so that the oversam bumper 150 and the main body 102 are in surface contact with each other. . At this time, the oversam bumper 150 can double shock absorption through the elastic force of the elastic member 140 and the damping of the buffer 154 having the rubber material. That is, the shock absorbing capability of the oversam bumper 150 can be improved.

In addition, the oversam bumper 150 according to the present invention can improve the degree of freedom in design. Since the conventional oversam bumper does not rotate, it is necessary to design the oversam bumper in consideration of the direction of contact with the main body when mounting the oversam bumper on the opening / closing device. In other words, in the past, the oversam bumper had to be designed so that it could be in surface contact with the main body without rotating. Even with such a design, surface contact may still not be achieved due to possible component scattering during assembly of the vehicle. However, since the oversam bumper 150 according to the present invention is rotatable, there is an advantage that the surface contact is possible through rotation even if there is a slight error. In addition, the noise inside the vehicle can be reduced by reducing the noise that can be caused by the line contact of the oversam bumper. Thus, the user's convenience of the vehicle can be improved.

The foregoing has shown and described specific embodiments. However, it should be understood that the present invention is not limited to the above-described embodiment, and various changes and modifications may be made without departing from the technical idea of the present invention described in the following claims .
