Description

Support bracket, picking workpiece and vehicle instrument panel

Technical Field

The invention relates to the field of vehicle part processing, in particular to a supporting bracket of a vehicle instrument panel and a picking workpiece for the same.

Background

In some processes, there is often some enclosed installation space, subject to the particular structure. For example, the front mounting point of the instrument panel is a closed mounting space in the vehicle body structure. In particular, the instrument panel typically includes an outer sheet metal part and an inner sheet metal part, and a support bracket is typically provided therebetween to increase the torsional strength of the two-layer sheet metal parts. To take strength, weight and cost into consideration, the support bracket is usually configured as a box in a closed space. In this case, if the two-layer sheet metal member and the support bracket are fastened, it is inevitable to perform the fastening operation by inserting the fastening workpiece into the closed space of the support bracket. If the fastening workpiece falls into the closed space due to an error during the operation, it is difficult to take out the fastening workpiece. This is mainly due to the fact that the through-holes for the mounting operations are small and the fastening pieces can roll inside, so that it is difficult to search completely for the enclosed space inside the support bracket; on the other hand, if the through-hole is simply enlarged in size, the problem of picking up the dropped material can be solved, but the support strength of the support bracket itself may be greatly reduced, and the support bracket may lose its basic function. Therefore, how to design the reasonable size of the supporting bracket to satisfy both the requirement of taking out the parts and the requirement of strength is a technical problem to be solved in the field.

Detailed Description

Referring to FIG. 1, one embodiment of a support bracket 100 is shown. The support bracket 100 includes a support body 110 forming a closed inner space, and a through-process hole 111 is opened on a first surface of the support body 110, and the through-process hole 111 is used for picking up a workpiece 200 and/or fastening the workpiece. In addition, as a general application of the present component, the fixing of the support bracket 100 to the component to which it is to be mounted may also be achieved through the through-process hole 111. Most critically, to achieve free access to the process via 111 for picking up workpieces while carrying fastened workpieces, attention will be directed hereinafter to a design that lists the parameters of interest,

first, the maximum size of the process via 111 is B. Wherein, for the through hole 111, when it is a circular hole, the maximum dimension B is the diameter of the circular hole correspondingly; when the square hole is formed, the maximum size B is correspondingly the diagonal length of the square hole; when it is a profiled hole, the maximum dimension B is correspondingly the maximum length that can be achieved in the profiled hole, etc., not to mention one by one. In consideration of the processing difficulty, the strength of the workpiece, and other factors, a preferred scheme is to use a circular hole as the through hole 111.

Second, the process dimension of the support bracket 100 is b. It means that the size data is reserved for the convenience of processing such as machining and molding. For example, in one embodiment, 10mm may be reserved.

Further, the maximum dimension of the pickup workpiece 200 passing through the process via 111 is L. Which means the size of the entire picked-up workpiece as it passes through the process via 111 in the most extreme case for picking up a fastened workpiece. The details of this section relating to the size of the picked-up workpiece will be described in detail later in connection with fig. 2.

In addition, the maximum size of the fastening workpiece is l. Wherein the understanding of the maximum dimension l is described by way of example for a bolt. Bolts typically include nuts and studs, and the maximum size that may exist for a bolt is the diameter of the nut or the overall height of the stud plus nut, or even other parameters. In this case, only one of the largest parameters is selected as l.

When the parameters satisfy that B-B is more than or equal to L + L, namely B is more than or equal to L + L + B. In the case of a minimum meeting the design criteria, i.e. B = L + B, it is then possible to achieve that the picking-up piece can carry the fastening piece freely in and out of the fabrication through hole 111 in any extreme case, i.e. to ensure the basic requirement of being able to pick up the part in the drop support 100

Further, when the farthest distance between the edge of the through-process hole 111 and the inner space of the support body 110 is A, the maximum size of the picking workpiece 200 that can protrude into the inner space of the support body 110 is L1, and L1 ≧ A. It will be ensured at this point that the picking up work piece 200 can reach every corner of the interior space of the support body 110, so that the dropped fastening work piece can be picked up without fail. It should be appreciated that L ≧ L1 because L1 is most likely only a portion of L.

Referring again to fig. 1, it can be seen that the through-process hole 111 is disposed at a central position of the first surface of the support body 110. The advantage of this arrangement is that the distances from the process through hole 111 to the locations in the enclosed space are relatively different, the portion of the pick-up work piece extending into the enclosed space does not need to be set too long, and the pick-up operation is more easily performed successfully. Of course, as other alternative embodiments, when the first surface of the support body 110 has a rectangular shape, the through-process holes 111 are arranged on a center line of the rectangular shape along a long side or a short side of the first surface.

In addition, to further facilitate the installation of the support bracket 100, a mounting skirt 120 is further provided on a side edge of the support body 110 on a second surface facing away from the first surface.

Referring to fig. 2, an embodiment of picking up a workpiece 200 is shown. The pick-up work piece 200 may be used to support the rack 100 from the previous embodiments. Specifically, the pickup workpiece 200 includes: a grip portion 210 for an operator to operate and a pick-up portion 220 for picking up parts dropped in the closed interior space of the support cradle 100. The maximum dimension of the holding portion 210 and the picking portion 220 passing through the through-process hole 111 together is L. Taking the rod-shaped grip portion 210 and the rod-shaped pickup portion 220 shown in fig. 2 as an example, L in this case represents the diameter of the rod-shaped grip portion 210 and the entire length of the rod-shaped pickup portion 220. Because, throughout the entire loss process, only the aforementioned parts are necessary to pass through the process through-hole 111 into the interior of the support body 110. Further, the maximum dimension of the pick-up portion 220 that can protrude into the interior space of the support body 110 is L1. Since the diameter of the gripping portion 210 is dimensioned to provide no further aid to the picking process after entering the inner space of the support body 110, it is mainly relied upon that the picking portion 220 seeks and picks up the falling fastening work pieces in this inner space.

Optionally, to facilitate the pick-up operation, a magnetic element 221 may also be provided at the end of the pick-up portion 220 to attract the drop fastening workpiece.

As can be seen from the above description, according to the embodiments of the supporting bracket 100 and the picking-up workpiece 200 of the present invention, by adopting specific dimensional designs for each part or each element, various fastening workpieces which are mistakenly dropped into the enclosed internal space of the supporting main body 110 can be obtained under any extreme conditions, the problem that the dropped parts are difficult to take out is solved, and the opening size of the process through hole 111 is ensured not to affect the supporting strength of the supporting bracket 100, so as to preserve the original technical effects. Of course, although it is emphasized herein that the size of the through-process via should be at least greater than or equal to a certain range, it is not possible to enlarge the size of the through-process via indefinitely, as those skilled in the art will appreciate, but rather, the upper limit of the size of the through-process via needs to be controlled to form an optimal size range while taking into account the support strength of the support bracket as appropriate.

Furthermore, although not shown in the figures, the present invention also provides an embodiment of a vehicle instrument panel. The vehicle instrument panel includes: the support bracket 100 in the foregoing embodiment, and the outer panel sheet metal member and the inner panel sheet metal member; wherein the support bracket 100 is supported between the outer and inner dash sheet metal parts. According to the vehicle instrument panel, the support bracket 100 is erected in the middle of the multi-layer sheet metal part, so that the torsional strength of the vehicle instrument panel is effectively improved.

The above examples have mainly described the support bracket, the pickup work, and the vehicle instrument panel of the present invention. Although only a few embodiments of the present invention have been described, those skilled in the art will appreciate that the present invention may be embodied in many other forms without departing from the spirit or scope thereof. Accordingly, the present examples and embodiments are to be considered as illustrative and not restrictive, and various modifications and substitutions may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
