Technical Field

[0001] The invention belongs to the field of automobiles, and in particular to an automobile wire-type grille. Background Art

[0002] Internal combustion engine vehicles need to take in air from the outside environment when driving in order to cool the engine, gearbox, and air conditioner. In order to ensure that there is sufficient air entering while driving, there is usually a grille in the middle of the front fender.

[0003] Currently, the main grille styles include sheet, dot matrix, mesh, and so on. The rear portion is generally a one-piece injection-molded component forming the base frame, with chrome trim mounted on top. In the event of a rear-end collision or other vehicle collision, the grille is easily damaged, requiring the entire assembly to be repaired or replaced, which is costly and inconvenient. Furthermore, with the growing demand for personalized exterior design, changing the color or material of a traditional front grille requires disassembling the entire front bumper and then the grille. This process is complex and time-consuming, making it virtually impossible for users to perform this task manually. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a wire-type automobile grille to solve the above problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0010] Furthermore, the starting end fixing member includes a starting boss and a fixing block; the fixing block is fixed on the front bumper body at the starting end of the pull wire, the starting bosses are symmetrically arranged on both sides of the pull wire, and the gap between the symmetrically arranged starting bosses is smaller than the diameter of the fixing block.

[0011] Furthermore, the end fixing member includes a stud, an end boss and a nut;

[0012] The end boss is fixed on the front bumper body at the end of the pull wire. The end boss is symmetrically arranged on both sides of the stud. One end of the stud is connected with a nut, which contacts the symmetrically arranged end boss. The other end of the stud is connected to the pull wire.

[0013] Furthermore, a gasket is provided at the contact portion between the nut and the end boss;

[0014] A circular ring is fixed on the other end of the stud, and the pull wire passes through the circular ring and is fixed through the aluminum sleeve.

[0015] Furthermore, the fixing column is conical, and the tip of the conical fixing column is fixed on the front bumper body.

[0016] Preferably, a snap-on platform is provided on the grille sheet, a groove is provided on the top of the snap-on platform, a metal sheet is provided inside the groove, and the metal sheet clamps the pull wire and is snapped into the groove.

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below with reference to specific embodiments, which are intended to explain the present invention rather than to limit it.

[0033] Example

[0034] like Figure 1 As shown, a wire-stayed grille structure assembly for an automobile of the present invention comprises: a plurality of grille pieces 1, wires 2 and a front bumper body 3.

[0035] The pull wires 2 are fixed on the front bumper body 3 , and the pull wires 2 are interwoven on the front bumper body 3 to form a mesh structure; a plurality of grille pieces 1 are fixed on the mesh structure of the pull wires 2 through a snap-fit ​​structure.

[0036] The grille sheet 1 can be in various shapes and can be of uniform or uneven thickness. The outer surface of the grille sheet 1 can be made into various colors, materials, patterns, and ridges to achieve a preset design effect. In this embodiment, for ease of description, a parallelogram-shaped grille sheet 1 of uniform thickness is used for illustration.

[0037] The array pattern formed by a large number of grid pieces 1 can be complex and varied, and a simple horizontal and vertical equal-spaced arrangement is used as an example for explanation.

[0038] The pull wire 2 can be a single continuous one or multiple discontinuous ones. Figure 2 As shown, in this embodiment, a single continuous cable is used as an example. The front bumper body 3 is provided with a plurality of fixing posts 32, around which the cable 2 is interwoven to form a mesh structure. The ends of the cable 2 are respectively fixed to the front bumper body 3 by a starting end fixing member 31 and an end fixing member 33. The diameter of the cable 2 ranges from 1 to 3 mm, and in this embodiment, a diameter of 1 mm is used as an example.

[0039] like Figure 3 As shown, the starting end of the pull wire 2 is fixed to the front bumper body 3 through the starting end fixing piece 31, and is wound through the numerous fixing columns 32 on the front bumper body 3. After reciprocating, it forms an interwoven network, and is finally tightened by the adjusting thread of the end fixing piece 33 and fixed to the front bumper body 3.

[0040] The starting end fixing piece 31 includes a starting boss 311 and a fixing block 312; the fixing block 312 is fixed on the front bumper body 3 at the starting end of the pull wire 2, and the starting boss 311 is symmetrically arranged on both sides of the pull wire 2, and the gap between the symmetrically arranged starting bosses 311 is smaller than the diameter of the fixing block 312.

[0041] The cable 2 can be made of either rust-resistant metal wire or plastic-coated steel wire, and its color can be customized to suit the design. The fixing block 312 can be a secure lead seal or a tightly compressed aluminum sleeve, ensuring that the cable 2 does not slip. When the cable 2 passes through the starting boss 311, creating a gap, the fixing block 312, with a diameter larger than the gap, will be caught by the starting boss 311, securing the cable 2 at its initial stage.

[0042] like Figure 4As shown, the end fixing member 33 includes a stud 333, an end boss 334, and a nut 336. The end boss 334 is fixed to the front bumper body 3 at the end of the cable 2. The end bosses 334 are symmetrically arranged on either side of the stud 333. One end of the stud 333 is connected to a nut 336, which contacts the symmetrically arranged end bosses 334. The other end of the stud 333 is connected to the cable 2. A gasket 335 is provided at the contact point between the nut 336 and the end boss 334. A circular ring is fixed to the other end of the stud 333, and the cable 2 passes through the ring and is fixed through the aluminum sleeve 332.

[0043] The end of stud 333 is annular. After the end of cable 2 passes through the ring of 333, it is compressed and fixed by aluminum sleeve 332, completing the connection with stud 333. The threaded end of stud 333 passes through gasket 335 and nut 336, respectively. Nut 336 has raised ears on both sides to facilitate manual tightening or loosening. During installation, rotate nut 336 clockwise to tighten cable 2. Finally, adjust gasket 335 and nut 336 to ensure that they are firmly stuck between the two end bosses 334 and do not fall off.

[0044] A plurality of fixing posts 32 are provided on the front bumper body 3 , and the pulling wire 2 can go around the fixing posts 32 to adjust its direction during the reciprocating routing process.

[0045] The fixing column 32 is conical in shape, and the tip of the conical fixing column 32 is fixed on the front bumper body 3, that is, the diameter of the fixing column 32 is smaller at the end close to the front bumper body 3, and the diameter is larger at the end farther away from the front bumper body 3. This ensures that when the pull wire 2 passes around the fixing column 32, it can fit the end with the smaller diameter of the front bumper body 3 and is not easy to fall off.

[0046] The starting end fixing piece 31, the end fixing piece 33 and the fixing column 32 are all injection-molded integrally with the front bumper body 3. The starting end fixing piece 31, the end fixing piece 33 and the fixing column 32 components can also be welded to the front bumper body 3 by hot melt welding.

[0047] like Figure 5 As shown, taking a single grille piece 1 as an example, each grille piece 1 has four metal clips on the back, two horizontal clips to ensure that the horizontal cable 2 is firmly clamped, and two vertical clips to ensure that the vertical cable 2 is firmly clamped. After each grille piece is arranged and fixed in this way, a dot matrix grille is formed.

[0048] The cable fixing method can be varied, but all of them do not deviate from the two-end fixed and middle winding method described in this invention. When the cable 2 is changed to form a different staggered pattern, the corresponding clip position and angle on the back of the grille plate 1 need to be adjusted accordingly, but they do not deviate from the metal clip connection method described in this invention.

[0049] First, a single grille piece is fixed by a snap-on method, which is convenient for assembly and disassembly. The owner can disassemble and replace the blades by himself without any tools, which is convenient for maintenance and personalized modification of color and material. Secondly, the number of parts in the grille assembly is very small, and there are no thin strip grille brackets, which ensures low processing difficulty and high product qualification rate. In addition, since most of the grille pieces 1 are exactly the same (the four middle longitudinal grille pieces are different in the present invention), all blades can be produced with 6 micro molds, which increases the product sharing rate and further reduces costs. From the perspective of automobile performance, the diameter of the grille wire is small, and the air resistance generated during driving is much lower than that of traditional plastic brackets (at least 5mm thick), which ensures higher cooling air intake efficiency and better cooling performance under the same grille opening area.

[0050] A snap-fit ​​platform 11 is provided on the grid plate 1 , a groove is provided on the top of the snap-fit ​​platform 11 , a metal sheet 12 is provided inside the groove, and the metal sheet 12 clamps the pull wire 2 and is snapped into the groove.

[0051] In this embodiment, a single grille sheet 1 can be made of PC, ABS, or other materials. Four concave-shaped latching platforms 11 are located on its back. These platforms and the grille sheet 1 are integrally injection molded. Two of these latching platforms 11 are coaxially arranged horizontally for retaining transverse cable connections, while the other two are coaxially arranged longitudinally for retaining longitudinal cable connections. Each latching platform 11 is mounted with an "M"-shaped metal sheet 12 for retaining the cable connections.

[0052] like Figure 6 As shown, each protrusion of a single grille plate has a square groove 111 on each side. To match, the metal plate 12 has a square piece 121 on each side that is slightly smaller than the square groove 111 and is warped inward. When assembled, the warped part of the metal plate will tilt and snap into the square groove 111, thus securing the snap-in platform 11 to the metal plate 12.

[0053] When installing the grille assembly, first secure the cable's starting end fixture 31. Then, wind the cable through the fixing post 32 according to a predetermined pattern. Once completed, tighten and secure it via the end boss 334. Install the metal sheet 12 onto the snap-on platform 11 of each grille piece 1. Then, firmly snap each grille piece 1 into place at each intersection of the cable 2. Finally, complete the front bumper assembly and install it on the vehicle.

[0054] To remove the grille, there's no need to disassemble the front bumper assembly. Simply grasp the grille 1 and pull it horizontally toward the front of the vehicle. To install a new grille, first assemble the grille 1 and metal sheet 12. Align the intersection of the tie wires 2, ensuring the horizontal and vertical tie wires 2 align with the horizontal and vertical grooves of the metal sheet 12, respectively. Then, press firmly toward the rear of the vehicle to ensure the tie wires 2 are firmly seated in the grooves of the metal sheet 12. Installation is complete.

[0055] If the grille assembly needs to be disassembled, all grille pieces 1 must be disassembled as described above first, then the nut 336 must be rotated counterclockwise to loosen the end of the pull wire and then remove the pull wire 2 in the order of winding. Be careful to avoid tangling the wire.

[0056] During normal vehicle operation, the grille 1 is fixed at the intersection of the tension wires and will not rotate or swing up and down, left or right, ensuring a secure installation. If the grille 1 collides with a slightly larger object such as a stone or a small animal, the tension wires 2 form a mesh with a certain degree of elasticity that can absorb kinetic energy, preventing damage to the grille.
