Description

Buckle subassembly, car light and vehicle

Technical Field

The present disclosure relates to a buckle assembly, and a vehicle lamp and a vehicle having the buckle assembly.

Background

In the engineering field, it is often necessary to assemble different parts, wherein a snap-fit is a common assembly structure. Snap-fit fittings, such as plug-in or slide-in fittings, common in the related art, for example, utilize a male snap that slides into a female snap and snaps into place, providing a secure attachment therebetween. This fixing may also be detachable. However, since the insertion of the pin is often unguided, it is prone to shifting during insertion, thereby causing even dislocation, jamming or locking at undesired locations.

To this end, there is a need in the art for a snap assembly that is simple in construction, occupies a small space, and remains securely fixed, and that is adapted to guided relative fit between the components in place.

Detailed Description

The technical solution of the present disclosure is further specifically described below by way of examples and with reference to the accompanying drawings. In the description, the same or similar reference numerals denote the same or similar components. The following description of the embodiments of the present disclosure with reference to the accompanying drawings is intended to explain the general inventive concept of the present disclosure and should not be construed as limiting the present disclosure. Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. However, one or more embodiments may be practiced without these specific details.

According to an embodiment of the present disclosure, as shown in fig. 1(a), 1(b) and 2, the buckle assembly 1 includes a female buckle 10 and a male buckle 20. It is noted here that, for the sake of clarity, only the box 10 and the pin 20 are shown, and the body, in which the components of the box and/or pin are preferably integrally formed, is not shown. At least one female and/or male thread is formed on the body of the respective component, which in the connected state of the components engage with each other, for example plug-in.

In the illustrated example, referring to fig. 2, the female buckle 10 has a hollow cavity 13 extending from an inlet side 11 to an outlet side 12 and being open outward at both the inlet side 11 and the outlet side 12, the cross-sectional dimension of the hollow cavity being tapered in a lateral direction, i.e., a horizontal direction of fig. 2, from the inlet side 11 (rear end) to the outlet side 12 (front end) opposite to the inlet side 11. In other words, the hollow cavity 13 of the female snap 10 is tapered. For this purpose, the hollow cavity 13 of the box 10 may additionally be tapered in a vertical direction transverse to the transverse direction towards the outlet side 12. It is noted that the shape of the box 10 is schematic, but it may also have other shapes, for example it may have a cross section of constant size, thus being cylindrical. The box may have a uniform wall thickness.

Referring to fig. 1(a), 1(b), a hollowed-out portion 210 is formed in the pin 20, thereby dividing the pin 20 into a main body 21 and a tab 22. The body 21 has a plate shape. The hollow part is in a U shape. In the state that the pin and the box are well joined, the open side of the U-shaped cutout faces the outlet side 12. For this purpose, it can be seen that a through-hole is formed in the pin 20 in the thickness direction thereof, the tab 22 extending from the side of the through-hole facing the front end of the body 21 viewed in the joining direction X towards the inside of the opening, wherein the tab 22 is spaced apart from the other sides of the through-hole. Tab 22 is connected to body 21 at base 221 (i.e., tab 22 transitions into body 21 at base 221) and has a top side 225 opposite base 221. Referring to FIG. 3, adjacent to the top side 225 of the tab 22 are an upper surface 223 and a lower surface 224, the lower surface 224 being on the same side as the first surface 226 of the body 21, the upper surface 223 and the lower surface 224 being opposed. Here, the tab 22 protrudes beyond the first surface 226 of the body 21 in the thickness direction of the body 20. To this end, the tongue 22 has a cross section that gradually increases from its base 221, which is connected to the body 21, to the top side 225. The upper surface 223 of the tongue 22 is planar and the lower surface 224 slopes away from the upper surface 223 from the base 221 to a top side 225, forming an increasing thickness tongue, the top side 225 extending from the rear edge of the upper surface 223 to the rear edge of the lower surface 224. Thus, during the engagement of the pin 20 starting from its front end gradually from the inlet side 11 to the outlet side 12 of the box 10, the tab 22 gradually slides with its inclined lower surface 224 over the inner wall of the hollow cavity of the box 10, and finally abuts with the top side 225 against the outlet side 12 of the box 10, so that the top side 225 prevents the pin 20 from receding into the box 10, thereby achieving the locking of the pin 20 to the box 10.

In other words, the tongue slides with its lower surface 224 and top side 225 successively over the inner wall of the box and with the top side 225 abuts against the outlet side 12 of the box 10.

The tongue 22 is designed to be elastically deformable so as to be elastically deformable during engagement of the pin with the box.

Preferably, the upper surface 223 of the tab 22 is in a plane with the second surface 222 of the body 21 opposite the first surface 226.

The intersection of lower surface 224 and top side 222 of tab 22 projects beyond first surface 226.

One side of the female button 10, for example, the middle of the top side as shown in fig. 2, is additionally formed with a circumferentially outward bulge extending between an inlet side 11 and an outlet side 12 along the length direction of the female button 10. A groove 30 is formed due to the swelling, thereby allowing the hollow cavity 13 to have a convex-shaped cross section. The dimensions of the sections on both sides of the hollow cavity 13 are adapted to the thickness of the body. Preferably, the first 226 and second 222 surfaces of the main body abut against sections of two sides of the inner wall of the hollow cavity 13 during engagement, thereby achieving a reliable guidance of the pin in the box. The groove 30 is used to at least partially receive the tab during engagement. To this end, the depth of the groove 30 should not be less than the dimension of the tab that protrudes beyond the first surface, particularly if the upper surface 223 of the tab is flush with the second surface 222.

As an example, the box 10 having the groove 30 is formed by molding.

As shown in fig. 1(a), 1(b) and 3, the body 21 of the male buckle 20 is gradually inserted into the hollow cavity 13 of the female buckle 10 from the front end thereof. At this time, the tab 22 connected to the front end of the body 21 slides with the lower surface 224 and the top side 225 thereof successively over the inner wall of the box 10, finally with the top side 225 abutting against the outlet side 12 of the box 10, thereby completing the insertion and holding of the pin 20 in place in the box 10 guided by the hollow cavity. During this time, the tab 22 is elastically deformed before the tab 22 abuts against the outlet side 12 of the female buckle 10, and after the abutment is completed, the tab 22 is elastically restored.

In another embodiment, as shown in fig. 4(a), 4(b), the male buckle 20 'further comprises two ribs 23 and 24 formed on a second surface 222 of the body of the male buckle 20' opposite the tongue lower surface 224. Preferably, the ribs extend parallel to one another in the longitudinal direction of the pin 20' and are arranged spaced apart from one another on both sides of the tongue. The arrangement of the tabs is similar to the example in fig. 1(a), 1(b), and will not be described again here.

By way of example, the ribs 23, 24 are formed integrally with the pin 20', for example by moulding.

Obviously, the number of ribs is not limited to two, and an appropriate number of ribs may be provided as needed. Through setting up the rib, can improve the structural strength of pin thread.

The cross-sectional shape of the hollow cavity 13 of the box 10' shown in fig. 5 is different from the previously described letter-convex shape, which has a rectangular cross-section.

As shown in fig. 6, the body 21 of the pin 20 'is gradually inserted into the hollow cavity 13 of the box 10' from the front end thereof. Preferably, the body 21 abuts with two ribs 23, 24 formed on its flat second surface 222 against one inner wall of the box 10 'accommodating the pin 20', and the first surface 226 of the body 21 abuts against the opposite other inner wall of the box 10 ', thereby gradually sliding the body 21 into the hollow cavity 13 of the box 10' along the engaging direction X; at the same time, the tongue 22 connected to the front end of the main body 21 slides with its lower surface 224 and top side 225 sequentially over the other inner wall of the box 10 ', finally with the top side 225 abutting against the outlet side 12 of the box 10', thereby completing the insertion and holding in place of the pin 20 'in the box 10'.

In this example, if the hollow cavity is tapered, the rib may have a varying cross-section in its length extension, for example a tapering cross-section in a direction towards the front end of the pin.

Thus, with such an arrangement as described above, the engagement of the pin into the box 10 'is guided by the ribs extending preferably parallel to one another in the engagement direction of the pin 20' and spaced apart from one another in a direction transverse to the engagement direction, and at the same time by means of the tongue which is elastically deformed during the engagement, which facilitates the guiding and fixing in place of the pin 20 'inserted into the hollow cavity 13 of the box 10'. The tab 22 is elastically deformable before the tab 22 abuts against the outlet side 12 of the female buckle 10', and the tab 22 is elastically restored after the abutment is completed.

The height of the ribs should be such that when the tabs are elastically deformed, no portion of the tabs extends beyond the plane defined by the longitudinal tops of the ribs.

Preferably, the tip of the rib transitions into the body along its longitudinal extension in a tapering manner, so that the pin engages into the box.

The engaged snap assembly of the embodiment of fig. 6 is cut at cut lines a-a and B-B, respectively, resulting in a cross-section as shown in fig. 8(a), 8 (B).

As can be seen from the section taken along the section line a-a, the front end of the male buckle is substantially flat, followed by a slightly obliquely rising slope of the rib, for example at an obtuse angle α in the range of 120 to 160 degrees with the flat front end, in other words, the two adjoining faces of the slope and the second surface 222 transition gently due to the obtuse angle being much greater than a right angle and closer to 180 degrees, so that a gradually decreasing cross-sectional change of the ribbed portion of the body 21 of the male buckle 20 ' from the rear portion to the front portion is achieved, so that the male buckle 20 ' is gradually inserted into the hollow cavity 13 of the female buckle 10 ' with an increasing cross-section.

As can be seen from the cross-section taken at the cut line B-B, the lower surface 224 of the tab is at an angle β within a predetermined angular range, e.g., 90 to 150 degrees, with the top side of the tab abutting the front end of the box immediately after the pin 20 ' is inserted through the box 10 ' into position once the first surface in contact with the lower surface 224 ceases to be in contact with the lower surface, thereby immediately effecting a lock and preventing the withdrawal of the tab 22 and thus the entire pin 20 '.

In this solution, the hollow cavity 13 has a relatively large cross-sectional dimension, which additionally contributes to avoiding thin steel and sharp steel structures in the mold, thereby increasing the service life of the mold.

The snap assembly described above can provide a guided secure fixing in place between two parts or assemblies. The snap assembly of the present disclosure may be mounted on a vehicle lamp or other component of a motor vehicle, and may be provided in any desired number at any location between the two components that need to be connected. However, it will be apparent that the snap assembly of the present disclosure may be used in other fields or devices as well.

It would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general disclosure, the scope of which is defined in the claims and their equivalents.
