[0002] At present, the structure of the glove box of automobile interior generally includes an inner bucket and an outer cover. The outer cover and the inner bucket are generally connected by friction welding. The welding strength of the two must reach a pull-off force of more than 1000N. Therefore, a grid-shaped uniformly distributed welding ribs are formed on the side of the inner bucket facing the outer cover.

[0003] Referring to the patent document with application number CN2021218576020, a new energy vehicle glove box is disclosed, which includes a glove box inner bucket and a glove box outer panel, the glove box outer panel is mounted on the outer wall of the glove box inner bucket, and the glove box outer panel and the glove box inner bucket are fixed by vibration friction welding. A grid-shaped welding rib is formed on one side of the glove box inner bucket facing the glove box outer panel.

[0004] Currently, there is a large discrepancy between the actual strength of the welding pull-out force of the welding ribs on the inner compartments of most glove boxes and the theoretical value. Most glove boxes need to undergo structural changes to meet the pull-out force standard requirements, which increases the R&D costs of the glove boxes. It can be understood that the welding ribs of existing glove boxes cannot provide sufficient pull-out force and have a problem of low welding strength. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a reinforced welding rib structure of a glove box, and to increase the friction welding strength between the inner bucket and the outer cover of the glove box by improving the arrangement structure of the welding ribs, thereby solving the problem of low welding strength in the past.

[0006] The utility model also provides a glove box, which has high strength and stable structure when assembled by friction welding, and can meet the industry standard requirements for friction welding pull-off force.

[0007] In order to solve the above-mentioned technical problems, the utility model discloses a reinforced welding rib structure of a glove box, which is used for a glove box, the glove box comprising an inner bucket and an outer cover plate friction-welded to the inner bucket, the welding rib structure comprising grid welding ribs arranged on a side of the inner bucket facing the outer cover plate, each corner position of the grid welding ribs is provided with at least two transverse welding ribs extending transversely and arranged at intervals in the longitudinal direction, the left side and the right side of the grid welding ribs are provided with at least two longitudinal welding ribs extending longitudinally and arranged at intervals in the transverse direction; each transverse welding rib and the longitudinal welding rib are integrally formed on the inner bucket.

[0008] The number of transverse welding ribs at each corner position of the grid welding ribs is more than three, and the lengths of the transverse welding ribs are unequal or partially equal.

[0009] The distance between two adjacent transverse welding ribs in the longitudinal direction is 7 mm to 10 mm.

[0010] The extending direction of each transverse welding rib is arranged horizontally with the moving direction of the friction welding.

[0011] Among them, the extension direction of each longitudinal welding rib is set parallel to the left side line or the right side line of the inner bucket.

[0012] Among them, the spacing in the transverse direction between two adjacent longitudinal welding ribs located on the same side of the inner bucket is 15mm to 20mm.

[0013] Wherein, the welding end surface of each longitudinal welding rib facing the outer cover plate is provided with a plurality of grooves arranged at intervals along the length direction of the longitudinal welding rib.

[0014] The groove width is 5 mm to 15 mm.

[0015] The groove depth is 1 mm to 4 mm.

[0016] The utility model also provides a glove box, comprising an inner bucket and an outer cover plate friction welded to the inner bucket, wherein the inner bucket is provided with the above-mentioned welding rib structure on one side facing the outer cover plate.

[0017] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0018] (1) By adding transverse welding ribs at each corner of the inner bucket, the welding area between the inner bucket and the outer cover is increased. Since the welding strength is proportional to the welding area, the friction welding strength between the inner bucket and the outer cover is improved, solving the problem of low welding strength in the past and ensuring that the actual welding strength can meet the pull-off force requirement of more than 1000N.

[0019] (2) By adding longitudinal welding ribs on the left and right sides of the inner bucket, when the transverse welding ribs are subjected to pull-off force, the longitudinal welding ribs will provide resistance and slow down the tendency of the transverse welding ribs to be pulled apart, so that a greater pull-off force is required to pull the inner bucket apart from the outer cover plate, further improving the friction welding strength and ensuring that the welding strength meets actual needs.

[0020] (3) By opening a plurality of grooves on the longitudinal welding ribs, the friction resistance of welding caused by the presence of longitudinal welding ribs connected to the welding end faces is avoided, and the welding ribs can be melted by friction heat. By opening the grooves, the contact area is reduced, thereby ensuring that friction welding can be carried out smoothly and the welding quality of the product is guaranteed.

[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, mechanism, product or end that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or ends.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] The utility model discloses a specific implementation method of a reinforced welding rib structure of a glove box, see Figure 1The glove box includes an inner bucket 2 and an outer cover plate 1 friction-welded to the inner bucket 2. It should be noted that the outer cover plate 1 of this embodiment has the same structure as the conventional outer cover plate 1, the side of the outer cover plate 1 facing the inner bucket 2 is a plane, and the outer cover plate 1 is not provided with any welding ribs. The improvement of this embodiment mainly lies in the layout design of the welding ribs of the inner bucket 2.

[0029] Please see Figure 2 A grid welding rib 20 is formed on one side of the inner bucket 2 facing the outer cover plate 1. The grid welding rib 20 includes a plurality of welding ribs arranged at intervals in the transverse and longitudinal directions. The welding ribs are arranged in a tic-tac-toe pattern.

[0030] As a further improvement, each corner position of the grid welding rib 20 (that is, the corner position of the friction interface of the inner bucket 2) is provided with three transversely extending transverse welding ribs 21, that is, transverse welding ribs 21 are arranged at intervals in the longitudinal direction of the inner bucket 2. In other embodiments, the number of transverse welding ribs 21 can be optimized according to the product structure, and the number can be greater than two. The more transverse welding ribs 21 are set, the larger the welding area they provide, and the higher the welding strength. In addition, the lengths of the various transverse welding ribs 21 are not equal or partially equal, and their specific lengths can be set according to the outer contour of the actual inner bucket 2, as long as it can ensure that the transverse welding ribs 21 can provide sufficient welding strength.

[0031] In the present embodiment, a plurality of transverse welding ribs 21 are located at the corner positions of the same grid welding rib 20, and the spacing between every two adjacent transverse welding ribs 21 in the longitudinal direction is 7 mm to 10 mm. This spacing can meet the requirements of the injection mold for producing the inner bucket 2. If the spacing is too small, for example, less than 7 mm, the transverse welding ribs 21 will appear too dense and thus will not be easy to demold. If the spacing is too large, for example, greater than 10 mm, the welding area provided under the same area conditions will be too small and the welding strength will decrease. Therefore, the most preferred solution is that the spacing between two adjacent transverse welding ribs 21 in the longitudinal direction is 7 mm to 10 mm, which can achieve smooth demolding of the inner bucket 2 during injection molding production and ensure that there is enough welding area during friction welding to ensure welding strength.

[0032] Please see Figure 2 , the left and right sides of the grid welding ribs 20 are each provided with two longitudinally extending longitudinal welding ribs 22, and the two longitudinal welding ribs 22 are arranged at intervals in the transverse direction. In other embodiments, the number of longitudinal welding ribs 22 can also be set to more than three, because the more the number of longitudinal welding ribs 22 is set, the larger the welding area provided, and the higher the welding strength. In addition, the lengths of the longitudinal welding ribs 22 are not equal or partially equal, and their specific lengths can be set according to the outer contour of the actual inner bucket 2, as long as it can ensure that the longitudinal welding ribs 22 can provide sufficient welding strength.

[0033] In the present embodiment, the spacing between two adjacent longitudinal welding ribs 22 on the same side of the inner bucket 2 in the transverse direction is 15 mm to 20 mm. This spacing can meet the requirements of the injection mold for producing the inner bucket 2. If the spacing is too small, for example, less than 15 mm, the longitudinal welding ribs 22 will appear too dense and thus difficult to demold. If the spacing is too large, for example, greater than 20 mm, the friction welding area provided under the same area conditions will be too small, and the friction welding strength will decrease. Therefore, the most preferred solution is that the spacing between two adjacent longitudinal welding ribs 22 in the transverse direction is 15 mm to 20 mm, which can achieve smooth demolding when producing the inner bucket 2 and ensure that there is enough welding area during friction welding to ensure welding strength.

[0034] It should be noted that each transverse welding rib 21 and each longitudinal welding rib 22 are formed on the inner bucket 2 , and it can be understood that each transverse welding rib 21 and each longitudinal welding rib 22 are an integrally formed structure with the inner bucket 2 .

[0035] Optionally, the arrangement direction of each transverse welding rib 21 is set horizontally with the movement direction of friction welding, which can be understood as the arrangement direction of each transverse welding rib 21 is parallel to the horizontal horizontal direction. Since the inner bucket 2 reciprocates relative to the outer cover plate 1 during the friction welding process, it is a reciprocating motion from left to right in the horizontal horizontal direction. By setting the arrangement direction of the transverse welding rib 21 parallel to the welding movement direction, the resistance brought by the transverse welding rib 21 during the friction welding process can be reduced as much as possible, ensuring that the transverse welding rib 21 can be fully fused to the outer cover plate 1. In combination, the arrangement direction of each longitudinal welding rib 22 is set parallel to the left side line or the right side line of the inner bucket 2. Such a design can better provide sufficient welding strength, ensure that the welding ribs are spread over the edge of the inner bucket 2, and avoid uneven welding force due to the existence of beveled edges or arc edges of the inner bucket 2.

[0036] In the actual welding process, friction welding requires the inner bucket 2 and the outer cover plate 1 to be pressed together, so it is necessary to apply vertical pressure to press the inner bucket 2 and the outer cover plate 1 together. After pressing, the inner bucket 2 needs to be allowed to reciprocate in the horizontal direction relative to the outer cover plate 1 to melt the material on the friction interface and achieve welding between the inner bucket 2 and the outer cover plate 1. When there are continuous and longitudinally extending longitudinal welding ribs 22 involved in welding, because the longitudinally extending longitudinal welding ribs 22 are perpendicular to the direction of friction movement, the longitudinally extending longitudinal welding ribs 22 will increase the friction resistance, resulting in the welding ribs not being easy to melt due to friction heat. The welding ribs here include transverse welding ribs 21 and longitudinal welding ribs 22, mainly longitudinal welding ribs 22. In order to solve this technical problem, combined with Figure 3In this embodiment, each longitudinal welding rib 22 is provided with a plurality of grooves 23 arranged at intervals along the length direction of the longitudinal welding rib 22 on the end surface facing the outer cover plate 1. By providing a plurality of grooves 23 on the longitudinal welding rib 22, a large friction resistance caused by the existence of continuous longitudinal welding ribs 22 is avoided, and the welding rib can be melted by friction heat. That is, by providing the grooves 23 on the welding end surface of the longitudinal welding rib 22, the contact area during friction welding is reduced, thereby ensuring that the welding end surface of the longitudinal welding rib 22 can be smoothly melted by friction heat during friction welding, thereby ensuring the welding quality of the product.

[0037] As a preferred solution, the groove width of the groove 23 is 5mm to 15mm, and the groove depth of the groove 23 is 1mm to 4mm. During friction welding, the welding end face of the longitudinal welding rib 22 can not only be fully melted and welded together with the outer cover plate 1, but also ensure that the longitudinal welding rib 22 has sufficient welding area to contact with the outer cover plate 1, and finally achieve high-strength welding. In addition, since the welding end face of the longitudinal welding rib 22 is provided with grooves 23 at intervals, when the welding end face of the longitudinal welding rib 22 is fully melted, the melted material will fill into the adjacent grooves 23, thereby achieving that the entire end face of the longitudinal welding rib 22 is fully melted material, which will greatly increase the contact area between the longitudinal welding rib 22 and the outer cover plate 1. Finally, with the design of the groove 23, not only can the welding end face of the longitudinal welding rib 22 be melted smoothly, but also the entire end face of the longitudinal welding rib 22 can be fully melted material, thereby achieving that the entire end face of the longitudinal welding rib 22 can be welded with the outer cover plate 1, and high-strength welding is achieved.

[0038] In this embodiment, preferably, the groove width of the groove 23 is set to 10mm, which can make the welding end face of the longitudinal welding rib 22 fully melt and welded with the outer cover plate 1 during friction welding, and can also ensure sufficient welding area, and finally achieve high-strength welding. It is further explained that if the groove width of the groove 23 is less than 5mm, it will not be able to effectively reduce the resistance of friction welding, and the welding end face of the longitudinal welding rib 22 cannot be fully melted; and if the groove width of the groove 23 is greater than 15mm, the area of ​​the welding end face of the longitudinal welding rib 22 will be too small, which will lead to too small contact area between the welding end face and the outer cover plate 1, and finally lead to insufficient welding strength.

[0039] In this embodiment, preferably, the groove depth of the groove 23 is set to 2mm or 3mm, which can make the weld end face of the longitudinal welding rib 22 overflow into the groove 23 during friction welding, ensuring that there is enough welding area to contact the outer cover plate 1, and can also ensure the strength of the longitudinal welding rib 22, preventing the longitudinal welding rib 22 from breaking or deforming during back-and-forth friction welding, and finally achieving high-strength welding. It is further explained that if the groove depth of the groove 23 is set to less than 1mm, the weld end face of the longitudinal welding rib 22 has not been fully melted, and the bottom of the groove 23 has already contacted the outer cover plate 1, which cannot effectively reduce the resistance of friction welding, that is, the weld end face of the longitudinal welding rib 22 cannot be fully melted;

[0040] However, if the groove depth of the groove 23 is greater than 4 mm, the welding end face of the longitudinal welding rib 22 may be easily broken or deformed due to its own insufficient strength, thereby making it impossible for the welding end face of the longitudinal welding rib 22 to fully contact the outer cover plate 1, that is, reducing the contact area between the welding end face of the longitudinal welding rib 22 and the outer cover plate 1, ultimately resulting in insufficient welding strength.

[0041] The reinforced welding rib structure of a glove box of this embodiment increases the welding area between the inner bucket 2 and the outer cover plate 1 by adding a plurality of transverse welding ribs 21 at each corner of the inner bucket 2. Since the welding strength is proportional to the welding area, the friction welding strength between the inner bucket 2 and the outer cover plate 1 is improved, solving the problem of low welding strength in the past, and ensuring that the actual welding strength can meet the pull-off force requirement of more than 1000N. In addition, by adding a plurality of longitudinal welding ribs 22 at the left and right sides of the inner bucket 2, when the transverse welding ribs 21 are subjected to the pull-off force, the longitudinal welding ribs 22 will provide resistance, slowing down the tendency of the transverse welding ribs 21 to be pulled apart, so that a greater pull-off force is required to pull the inner bucket 2 apart from the outer cover plate 1, further improving the friction welding strength, and ensuring that the welding strength meets the actual requirements.

[0042] This embodiment provides a glove box, such as Figures 1 to 3 As shown, the glove box includes an inner bucket 2 and an outer cover plate 1 friction-welded to the inner bucket 2, and the inner bucket 2 and the outer cover plate 1 are welded by the reinforced welding rib structure of the glove box mentioned above.

[0043] The glove box increases the welding area between the inner bucket 2 and the outer cover 1 by adding transverse welding ribs 21 at each corner of the inner bucket 2. Since the welding strength is proportional to the welding area, the friction welding strength between the inner bucket 2 and the outer cover 1 is improved, ensuring that the actual welding strength of the glove box can meet the pull-off force requirement of more than 1000N and meet the industry standard for friction welding pull-off force.

[0044] The glove box adds longitudinal welding ribs 22 on the left and right sides of the inner bucket 2. When the transverse welding ribs 21 are subjected to pulling force, the longitudinal welding ribs 22 will provide resistance to slow down the tendency of the transverse welding ribs 21 to be pulled apart, so that a greater pulling force is required to pull the inner bucket 2 apart from the outer cover 1, thereby further improving the friction welding strength of the glove box and ensuring that the welding strength of the glove box meets actual needs.

[0045] The glove box avoids increasing the friction resistance of welding due to the existence of longitudinal welding ribs 22 with continuous welding end faces by opening multiple grooves on the longitudinal welding ribs 22, ensuring that the welding ribs can be melted by friction heat. By opening the grooves, the contact area is reduced, thereby ensuring that friction welding can be carried out smoothly and the welding quality of the product is guaranteed.

[0046] Finally, it should be noted that the reinforced weld rib structure of a glove box disclosed in the embodiment of the utility model only discloses a preferred embodiment of the utility model, which is only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
