Description

Technical Field

[0001] This utility model relates to the field of laptop feet technology, and in particular to a double-injection molding structure for a laptop shell and a laptop shell. Background Technology

[0002] Computer feet consist of two parts: a hard plastic part and a soft plastic part. The hard plastic part is made of a relatively rigid plastic, while the soft plastic part is made of a soft plastic. The soft plastic part is generally made by injection molding onto the hard plastic part.

[0003] Currently, dual-injection molding is used to mold the hard plastic parts of the laptop casing and the hard and soft plastic parts of the laptop casing feet into a single mold. This reduces the number of molds, lowers mold costs, and eliminates the original hot-melt jig and hot-melt process, offering significant economic benefits. However, when producing laptop casings using this method, the soft and hard plastic parts of the laptop casing feet are prone to severe deformation after molding, significant wear during testing, and delamination. This affects the yield rate and manufacturing costs of laptop casings, and this problem urgently needs to be solved. Utility Model Content

[0027] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention.

[0028] like Figures 1 to 4 As shown, this utility model provides a dual-injection molded structure for a laptop shell, including a laptop shell body 1 and soft rubber feet 2. The laptop shell body 1 has a connecting protrusion 101 for mounting the soft rubber feet 2, and the soft rubber feet 2 has a receiving recess 202 for accommodating the connecting protrusion 101. The connecting protrusion 101 is at least partially accommodated in the receiving recess 202. A plug-in structure is provided between the soft rubber feet 2 and the laptop shell body 1. The plug-in structure is arranged around the connecting protrusion 101 or the receiving recess 202. Along the thickness direction of the laptop shell, the ratio of the thickness of the soft rubber feet 2 located at the receiving recess 202 to the thickness of the laptop shell body 1 located at the connecting protrusion 101 is 5:3. By setting the thickness ratio of the soft rubber pad at the recess 202 to the thickness of the laptop casing body 1 at the connecting protrusion 101 to 5:3, severe deformation and delamination of the soft and hard rubber parts of the laptop casing pads can be avoided after molding. The wear resistance of the soft rubber pads 2 can also be enhanced, thus improving the overall yield rate of laptop casing manufacturing.

[0029]

[0030] Table 1

[0031] As can be seen from Table 1, when the ratio of the soft rubber thickness (i.e., the thickness of the soft rubber pad 2) to the hard rubber thickness (i.e., the thickness of the laptop shell body 1) is 5:3, all test data are in good condition. When the thickness of the soft rubber pad 2 located at the recess 202 is uneven, the maximum thickness of the soft rubber pad 2 located at the recess 202 is compared with the thickness of the hard rubber.

[0032] The insertion structure includes an insertion protrusion 201 and a corresponding insertion hole 102. The insertion hole 102 is located on the laptop casing body 1, and the insertion protrusion 201 is located on the soft rubber foot pad 2; or, the insertion hole 102 is located on the soft rubber foot pad 2, and the insertion protrusion 201 is located on the laptop casing body 1. By setting the insertion protrusion 201 and the insertion hole 102, the contact area between the soft rubber and the hard rubber can be increased, thereby increasing the insertion and removal force between the soft rubber and the hard rubber, avoiding the problem of glue separation during use of the laptop casing. Moreover, the above structure is simple and easy to use in the two-shot molding process.

[0033] In this embodiment, the soft rubber feet 2 are provided with multiple insertion protrusions 201, which are arranged sequentially around the receiving recess 202. The insertion holes 102 on the laptop casing 1 correspond one-to-one with the insertion protrusions 201. When the connecting protrusions 101 and the receiving recess 202 are connected, the position of the soft rubber feet 2 on the laptop casing 1 can be positioned and limited. By providing multiple insertion protrusions 201 around the receiving recess 202 on the soft rubber feet 2, the problem of glue separation at the edge of the opening of the receiving recess 202 can be avoided.

[0034] In this embodiment, the soft rubber feet 2 are elongated, with insertion protrusions 201 at both ends. The elongated shape of the soft rubber feet 2 increases the friction between the laptop casing and the supporting surface during use, preventing the laptop casing from slipping and improving user comfort. Since the stress generated by friction during use is concentrated at both ends of the elongated soft rubber feet 2, these ends are more prone to delamination. The insertion protrusions 201 at both ends strengthen the connection between the soft rubber feet 2 and the laptop casing 1, preventing delamination when subjected to significant stress.

[0035] The soft rubber feet 2 have three frustum-shaped protrusions 201 at one end, with the larger radius end connecting to the soft rubber feet 2 and the smaller radius end away from the soft rubber feet 2. The other end of the soft rubber feet 2 has a semi-circular protrusion 201 surrounding at least part of the connecting protrusion 101. The use of three frustum-shaped protrusions 201 at one end of the soft rubber feet 2 better adapts to the space allocation of the laptop casing and accommodates the connection requirements between the soft rubber feet 2 and the laptop casing body 1. The semi-circular protrusion 201, while ensuring the connection between the soft rubber feet 2 and the laptop casing body 1, offers better connection stability but requires more space. Using two different connection structures at both ends allows for flexibility based on the space layout requirements of the laptop casing and also satisfies the connection requirements between the soft rubber feet 2 and the laptop casing body 1.

[0036] In this embodiment, a reinforcing rib 2011 is provided on the semi-circular insertion protrusion 201, and the reinforcing rib 2011 extends along the protrusion direction of the insertion protrusion 201. By providing the reinforcing rib 2011 on the semi-circular insertion protrusion 201, the stability of the connection between the insertion protrusion 201 and the soft rubber foot pad 2 can be enhanced.

[0037] In this embodiment, a frustum-shaped insertion protrusion 201 and a long strip-shaped insertion protrusion 201 are provided on both sides between the two ends of the soft rubber foot pad 2. The insertion protrusions 201 are set according to the space requirements of the laptop shell, which enhances the connection stability between the laptop shell body 1 and the soft rubber foot pad 2. In this embodiment, the distance between each insertion protrusion 201 on the soft rubber foot pad 2 and the edge of the soft rubber foot pad 2 is 0.5-0.9mm.

[0038] The laptop casing 1 is square, and soft rubber feet 2 are provided at each of the four corners of the laptop casing. The soft rubber feet 2 are long strips, and each soft rubber foot 2 extends along the diagonal direction of the four corners of the laptop casing 1. In this way, the soft rubber feet 2 can distribute the weight of the laptop more evenly and avoid local pressure concentration. Especially when the laptop casing is subjected to uneven force (such as opening and closing the screen with one hand), this layout can enhance the ability to resist torsional loads. At the same time, the long strip soft rubber feet 2 increases the friction area with the contact surface, reducing the risk of the laptop sliding on smooth surfaces.

[0039] In this embodiment, the connecting protrusion 101 is elongated and the two ends of the connecting protrusion 101 are arc-shaped. This increases the contact area of ​​the two injection molding materials, forms a physical interlock, prevents delamination or delamination, and reduces stress concentration. It also avoids problems such as delamination caused by poor flowability of molten plastic or stress concentration at sharp corners.

[0040] The laptop casing 1 features a limiting step 103 surrounding the soft rubber feet 2. This limiting step 103 serves to restrict the soft rubber feet 2, further limiting their position when they are on the contact surface and preventing them from slipping out of their original position and causing issues such as glue separation. The width of the connecting protrusion 101 on the laptop casing 1 is 2.5-3.5mm.

[0041] This utility model also provides a notebook casing, including the double-injection molded structure of the notebook casing as described above.

[0042] In summary, by setting the ratio of the thickness of the soft rubber pad at the recess 202 to the thickness of the laptop casing body 1 at the connecting protrusion 101 to 5:3, severe deformation and delamination of the soft and hard rubber parts of the laptop casing pads after molding can be avoided. It can also enhance the wear resistance of the soft rubber pad 2, thereby improving the overall yield rate of laptop casing manufacturing.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
