Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1 to 3, the buckle comprises a cover cylinder 1 and a clamping piece 2, wherein the cover cylinder 1 is a plastic piece, the lower end of the cover cylinder is open, and the clamping piece 2 is fixed in an inner hole of the cover cylinder. Referring to fig. 4, the whole clamping piece 2 is sheet-shaped, a clamping interface 21 axially penetrating through the end face is formed on the clamping piece, eight check elastic clamping feet 22 matched with the connecting piece 3 are uniformly arranged at intervals in the circumferential direction of the clamping interface 21, the check elastic clamping feet 22 extend upwards along the radial direction of the clamping interface 21 to form an included angle between the axis of the check elastic clamping feet 22 and the plane where the clamping piece 2 is located is 30-50 degrees, the virtual circular diameter formed by the inner ends of the check elastic clamping feet 22 in a surrounding manner is 0.5-3 mm smaller than the outer diameter of the connecting piece 3, namely interference exists between the check elastic clamping feet 22 and the connecting piece 3, and then the effect of 'low insertion force and high extraction force' is realized when the clamping piece 2 is matched with the connecting piece 3. Referring to fig. 9, the connecting piece 3 passes through the mounting hole of the member to be mounted, and extends into the inner hole of the cover cylinder 1 to be in clamping fit with the non-return elastic clamping pin 22 on the clamping piece 2.
The clamping piece 2 is a steel piece and is made of high-strength and high-elasticity spring steel. Preferably, the spring steel is 65Mn steel. Because the cover cylinder 1 and the clamping piece 2 are manufactured and processed independently, compared with the mode that the clamping piece is injection molded in the cover cylinder, the manufacturing cost is lower.
In order to improve the connection stability and connection convenience of the clamping piece 2 and the cover cylinder 1, see fig. 5 to 8, the cover cylinder 1 comprises a containing section 11 and a mounting section 12, a first through hole 111 is arranged in the containing section 11, a second through hole 121 which is coaxially communicated with the first through hole 111 and axially penetrates through the upper end face and the lower end face of the mounting section 12 is arranged in the mounting section 12, and the aperture of the first through hole 111 is smaller than that of the second through hole 121. A plurality of notches 123 are formed at intervals on the upper edge of the mounting section 12, and the elastic limiting portion 122 is formed in the notches 123. The elastic limiting portion 122 includes a base end connected to the wall of the second through hole 121 of the mounting section and a protrusion correspondingly matched with the clamping piece 2.
In order to improve the assembly convenience, the outer diameter of the clamping piece 2 is 0.2-2 mm smaller than the aperture of the second via hole 121, that is, the clamping piece 2 and the second via hole 121 are in clearance fit. When the clamping piece 2 is assembled, the clamping piece 2 is pushed upwards by the opening at the lower end of the cover cylinder 1, and the elastic limiting part 122 is gradually extruded in the upward moving process of the clamping piece 2, so that the elastic limiting part 122 is stressed to expand outwards, and the clamping piece 2 enters the inside of the cover cylinder. After the clamping piece 2 moves upwards for a certain distance, the distance is generally 5-8 mm, the clamping piece 2 cannot be limited to move upwards continuously due to the limitation of the lower end of the containing section 11 in the cover cylinder 1, the elastic limiting part 122 rebounds at the moment so as to prevent the clamping piece 2 from falling back, the upper surface and the lower surface of the clamping piece 2 are respectively limited by the lower end surface of the containing section 11 and the elastic limiting part 122, and stable and reliable connection of the clamping piece 2 and the cover cylinder 1 is realized.
In order to realize that the resistance of the elastic limiting part 122 is smaller when the clamping piece 2 is pushed in, and the elastic limiting part 122 can rebound stably when the clamping piece 2 stops moving upwards, a first inclined surface and a second inclined surface are arranged on the bulge of the elastic limiting part 122, the first inclined surface is positioned above the second inclined surface, and the lower end of the first inclined surface is connected with the upper end of the second inclined surface; the inclination angles of the first inclined surface and the second inclined surface are adjusted according to the thickness of the clamping piece 2.
Six first bosses 112 are axially arranged on the wall of the first via hole 111, and the six first bosses 112 are uniformly arranged around the axis of the cover cylinder 1. Due to the effect of the first boss 112, after the connecting piece 3 enters the accommodating section 11 of the cover cylinder 1, the first boss 112 interacts with the outer wall of the connecting piece 3, so that the axial lead of the cover cylinder 1 and the axial lead of the connecting piece 3 are automatically aligned in a superposition manner.
The lower end of the first boss 112 is provided with a guiding inclined plane 113, and the guiding inclined plane 113 plays a role in guiding the connecting piece 3, so that the first boss 112 is prevented from blocking the connecting piece 3. The aperture of the virtual inner hole formed by surrounding the six first bosses 112 is 0.5-2.0 mm larger than the outer diameter of the connecting piece 3, namely, the first bosses 112 and the connecting piece 3 are in clearance fit, so that the buckle is smoother to press in the connecting piece 3, and the assembly efficiency is improved.
Six second bosses 114 are axially arranged on the outer side wall of the accommodating section 11, and a recess is formed between the adjacent second bosses 114, so that the structure can provide larger friction force and is beneficial to the installation or the disassembly of the buckle. The elastic stopper 122 described with reference to fig. 10 and 11 corresponds to a recessed position between the adjacent second bosses 114 in the axial direction of the casing 1. Referring to fig. 12 to 14, the mold 6 for manufacturing the can 1 is composed of an outer mold 61 and an inner mold 62 at the time of manufacturing the can. Generally, when producing the can 1 on a specific injection molding machine, the outer mold 61 is used as a rear mold, the inner mold 62 is used as a front mold, and the can be produced by simply using the inner and outer molds, without arranging various sliding blocks on the molds to facilitate the demolding.
The connecting structure of the vehicle component comprises a first component 4 and a second component 5, wherein a connecting piece 3 is fixed on the first component 4, a through hole for allowing the connecting piece 3 to pass through is formed in the second component 5, the buckle is pressed into a part of the connecting piece 3, which passes through the second component 5, and the connecting piece 3 is connected and fixed with a clamping piece 2 in the buckle so as to fix the second component 5 on the first component 1.
During the specific assembly, the relative position between the second component 5 and the first component 4 is adjusted, so that the connecting piece 3 passes through the through hole on the second component 5, then the buckle is pressed into the part of the connecting piece 3 passing through the second component 5, and the upper end of the connecting piece 3 extrudes the non-return elastic clamping pin 22 of the clamping piece 2, so that the non-return elastic clamping pin 22 expands outwards in a radial direction. The first boss 112 of the cover cylinder 1 and the outer wall of the connecting piece 3 interact, so that the axial lead of the cover cylinder 1 and the axial lead of the connecting piece 3 are automatically aligned in a superposition mode. When the lower end of the cover cylinder 1 is contacted and attached with the mounting surface of the second component 5, the assembly is in place, and at the moment, the non-return elastic clamping pin 22 can shrink inwards under the action of elasticity to interfere with the outer wall of the connecting piece 3, so that the friction force between the connecting piece 3 and the clamping piece 2 is increased, and the connection between the clamping buckle and the connecting piece 3 is stable and reliable.
The first component 4 is an aluminum vehicle body, the connecting piece 3 is of a cylindrical structure which is integrally formed with the first component 4 in a die-casting mode, and the second component 5 comprises a heat insulation pad, a sound insulation pad or a wheel cover lining plate which are connected with the aluminum vehicle body.
Referring to fig. 15 and 16, a smooth aluminum columnar connecting piece 3 is arranged at a hub package of a first component 4, namely an aluminum vehicle body, through holes are formed in a second component 5, namely a wheel cover lining plate, the through holes of the wheel cover lining plate are aligned and sleeved on the connecting piece 3, and then the buckle is clamped on the connecting piece 3, so that the wheel cover lining plate is connected with the hub package of a lower vehicle body.
Through test, when a conventional buckle is matched and connected with a threaded steel screw with M6 multiplied by 1.0-6h, the insertion force of 100N-130N and the extraction force of 390N-420N can be realized. When the buckle is matched and connected with a smooth aluminum columnar connecting piece with the diameter of 5.6-5.8 mm, the insertion force of 90N-115N and the extraction force of 390N-440N can be realized. When the buckle is connected with a smooth aluminum column, the insertion force is slightly reduced compared with the insertion force when the threaded steel screw is matched, and the extraction force is slightly improved compared with the extraction force when the threaded steel screw is matched.
An automobile comprises the buckle or the automobile component connecting structure.
