Description

Technical Field

[0001] The present application relates to the technical field of fasteners and connectors, and in particular to a connection structure and electronic equipment. Background Art

[0002] In the field of electronic equipment manufacturing, injection-molded plastic parts are often used in conjunction with bolts or screws to achieve a secure connection. However, when plastic parts are provided with angled connection holes, these holes are typically formed through a core-pulling process. The core-pulling distance of angled connection holes is relatively long, which complicates the design of the injection mold and makes demolding difficult. Reducing the depth of the angled connection holes to reduce demolding difficulty can lead to localized excessive thickness in the bottom wall of the connection hole, making it prone to quality defects such as bubbles and grooves in the injection molded parts, making it difficult to ensure the connection strength of the plastic parts. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a connection structure that can reduce the difficulty of injection molding and demoulding and can ensure the connection strength.

[0004] The present application also provides an electronic device having the above connection structure.

[0005] According to an embodiment of the present application, the connection structure includes a base and a connection portion;

[0006] Along the first direction, the connecting portion is connected to one side of the base, and the connecting portion and the base together enclose an empty slot, which is opened toward the second direction. The connecting portion is further provided with a connecting hole, and along the first direction, the connecting hole is located on a side of the empty slot away from the base, and the first direction is perpendicular to the second direction;

[0008] According to the connection structure of the embodiment of the present application, there are at least the following beneficial effects: the connection hole in the present application has an angle relative to the first direction and the second direction, so that the extension direction of the connection hole is inclined relative to the outer surface of the base bearing connection part, and the vacant groove is used to reduce the hole wall thickness of the connection hole toward the base, which is beneficial to improving the injection molding quality of the connection structure and ensuring the connection strength of the connection structure. In addition, the vacant groove can also reduce the depth of the connection hole on the basis of ensuring the relative position between the connection hole and the base, making it easier to pull the core out of the connection hole, and the vacant groove is opened in the second direction. When the injection core is pulled, the second direction is used to be arranged parallel to the horizontal plane. Therefore, during the injection molding production of the connection structure of the present application, the connection hole and the vacant groove can be demolded by two independent core pullings, thereby converting the longer inclined core pulling distance into a shorter inclined core pulling distance and horizontal core pulling. The shorter core pulling and horizontal core pulling are both convenient for demolding of the connection structure, effectively reducing the difficulty of injection molding and demolding of the entire connection structure.

[0010] According to some embodiments of the present application, the bottom wall of the connecting hole is perpendicular to the extension direction of the connecting hole, the extension direction of the connecting hole passes through the second slot section, and the side wall of the second slot section close to the connecting hole is parallel to the bottom wall of the connecting hole.

[0011] According to some embodiments of the present application, the connecting structure includes a first reinforcing portion, which is connected to the base along a first direction, and the first reinforcing portion and the connecting portion are both located on the same side of the base; and the first reinforcing portion is connected to the connecting portion along a second direction, and the first reinforcing portion is located on the side of the connecting portion that is away from the slot opening of the vacant slot.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0037] The following describes the embodiments of the present application in conjunction with the accompanying drawings:

[0038] refer to Figures 1 to 3According to the connection structure of the embodiment of the present application, it is produced by injection molding. The connection structure includes a base 100 and a connection portion 200. Along the first direction, the connection portion 200 is connected to one side of the base 100. The connection portion 200 and the base 100 together enclose an empty groove 210. The empty groove 210 is opened in the second direction. The connection portion 200 is also provided with a connection hole 220. Along the first direction, the connection hole 220 is located on the side of the empty groove 210 away from the base 100. The first direction is perpendicular to the second direction. The extension direction of the connection hole 220 has an angle with the first direction, and the extension direction of the connection hole 220 also has an angle with the second direction. The angle is not 0°, so that the connection hole 220 is tilted relative to the base 100. The connecting hole 220 and the vacant slot 210 have different extension directions. During injection molding production, the connecting hole 220 and the vacant slot 210 are defined by two independent core pulling cores, and the two core pulling cores have different pulling directions. The core pulling core used to define the connecting hole 220 is pulled out along the extension direction of the connecting hole 220, and the core pulling core used to define the vacant slot 210 is pulled out along the second direction (the second direction can be arranged to be parallel to the horizontal direction).

[0039] Thus, by providing the vacant slot 210 facing the second direction, the length of the connecting hole 220 is reduced without affecting the relative position between the connecting hole 220 and the base 100, thereby shortening the distance for inclined core pulling, making core pulling and demolding at the connecting hole 220 more convenient. In addition, the vacant slot 210 can be formed by horizontal core pulling, which is relatively simple, facilitating the simplification of the injection mold and making the connection structure easier to produce.

[0040] It should be noted that, compared with the connection structure that is only provided with an inclined connection hole 220 of a larger depth, the connection structure in the present application transforms the inclined connection hole 220 of a larger depth into an inclined connection hole 220 of a smaller depth and an empty groove 210 by providing an empty groove 210, thereby reducing the difficulty of injection molding and demolding of the connection structure, and can ensure the molding quality of the connection structure, so that the connection structure has good connection strength.

[0041] Specifically, during the injection molding process of the connection structure in the present application, the injection mold used includes a first core pulling and a second core pulling. The connection hole 220 is configured to be formed by the first core pulling, and the vacant groove 210 is configured to be formed by the second core pulling. The first core pulling moves along the extension direction of the connection hole 220, and the second core pulling moves along the extension direction of the vacant groove 210 (i.e., the second direction).

[0042] During the injection molding operation, the second direction can be arranged parallel to the horizontal direction. The extension direction of the connecting hole 220 passes through the vacant groove 210. The vacant groove 210 reduces the depth of the connecting hole 220. As a result, the movement distance of the first core pulling is shortened, making it easier to pull the core of the connecting hole 220 out of the molding process. The second core pulling is along the horizontal direction, which makes relatively inclined core pulling simpler and helps reduce the complexity of the injection mold. The vacant groove 210 is located on the side of the connecting hole 220 close to the base 100. On the basis of ensuring that the relative position of the connecting hole 220 and the base 100 remains unchanged, it can also reduce the local hole wall thickness of the connecting hole 220, avoiding the hole wall of the connecting hole 220 being too thick and causing molding defects, which helps improve the molding quality of the connection structure and ensure the connection strength.

[0043] The connection hole 220 formed by the core pulling is often configured to cooperate with a bolt or a screw to achieve fixation of other components.

[0044] refer to Figures 1 to 5 In some embodiments, the vacant slot 210 includes a first slot segment 211 and a second slot segment 212. The first slot segment 211 and the second slot segment 212 are adjacently arranged along the second direction and communicate with each other, allowing the second core pulling process to form the vacant slot 210 in one operation. From the second slot segment 212 to the first slot segment 211, the cross-sectional area of ​​the second slot segment 212 gradually decreases. The slot opening of the vacant slot 210 is located in the second slot segment 212. That is, along the second direction, in the direction of separation from the vacant slot 210, the slot opening of the vacant slot 210 gradually expands, facilitating the separation and formation of the vacant slot 210.

[0045] It should be noted that the cross-sectional area of ​​the second slot segment 212 should be understood as a cross section formed by crossing the second slot segment 212 along a plane perpendicular to the second direction, and can also be understood as the slot shape of the vacant slot 210 .

[0046] refer to Figures 1 to 5 In some embodiments, the bottom wall of the connection hole 220 is perpendicular to the direction in which the connection hole 220 extends, and the direction in which the connection hole 220 extends passes through the second slot section 212, meaning that the second slot section 212 is located on the side of the bottom wall of the connection hole 220. Furthermore, the sidewall of the second slot section 212 adjacent to the connection hole 220 is parallel to the bottom wall of the connection hole 220, further improving the thickness uniformity of the bottom wall of the connection hole 220. This effectively avoids differences in cooling rates caused by uneven thickness, thereby ensuring the molding quality and connection strength of the connection structure of the present application.

[0047] Specifically, along the extension direction of the connecting hole 220, the second groove section 212 is located on the side of the bottom wall of the connecting hole 220 close to the base 100, and the connecting hole 220 and the second groove section 212 are separated by a partition wall. The side of the partition wall facing the connecting hole 220 is the bottom wall of the connecting hole 220, and the side of the partition wall facing the second groove section 212 is the side wall of the second groove section 212, and the side of the partition wall facing the connecting hole 220 is parallel to the side facing the second groove section 212, so that along the extension direction of the connecting hole 220, the thickness of the partition wall is consistent at various locations, and further, when the partition wall is cooled during injection molding, the cooling speed at various locations is closer, which effectively avoids the generation of molding defects such as bubbles, and is beneficial to ensuring the connection strength of the connection structure.

[0048] In addition, the connecting hole 220 is tilted relative to the base 100, and the bottom wall of the connecting hole 220 is perpendicular to the extension direction of the connecting hole 220. Therefore, the bottom wall of the connecting hole 220 is tilted relative to the base 100, and then, the side wall of the second groove section 212 is tilted relative to the base 100, ensuring that the cross-sectional area of ​​the vacant groove 210 in the second groove section 212 gradually increases along the direction of leaving the vacant groove 210, thereby facilitating the core pulling forming of the vacant groove 210.

[0049] refer to Figures 1 to 5 In some embodiments, the connection structure includes a first reinforcement portion 310. Along the first direction, the first reinforcement portion 310 is connected to the base 100, and the first reinforcement portion 310 and the connection portion 200 are both located on the same side of the base 100. Along the second direction, the first reinforcement portion 310 is connected to the connection portion 200, and the first reinforcement portion 310 is located on the side of the connection portion 200 away from the notch of the vacant groove 210 to avoid blocking the core pulling forming of the vacant groove 210. The first reinforcement portion 310 is used to improve the connection strength between the connection portion 200 and the base 100, which is beneficial for the connection portion 200 to resist the force along the second direction, thereby ensuring the connection strength of the connection structure.

[0050] refer to Figures 1 to 5 In some embodiments, the connection structure further includes a second reinforcing portion 320. Along the first direction, the second reinforcing portion 320 is connected to the base 100, and the second reinforcing portion 320 and the connection portion 200 are both located on the same side of the base 100. Along the third direction, the second reinforcing portion 320 is connected to one side of the connection portion 200. The third direction, the second direction and the first direction are perpendicular to each other. The second reinforcing portion 320 is used to improve the resistance of the connection portion 200 to impact in the third direction, thereby ensuring the stability of the connection between the connection portion 200 and the base 100.

[0051] refer to Figures 1 to 5In other embodiments, the connection structure includes a first reinforcement portion 310 and a second reinforcement portion 320. Along the first direction, the first reinforcement portion 310, the second reinforcement portion 320, and the connection portion 200 are all located on the same side of the base 100 and are all connected to the base 100. Along the second direction, the first reinforcement portion 310 is connected to the side of the connection portion 200 facing away from the notch of the vacant slot 210 to enhance the impact resistance of the connection portion 200 along the second direction and prevent interference with the core pulling of the vacant slot 210. Along the third direction, the second reinforcement portion 320 is further connected to at least one side of the connection portion 200 to enhance the impact resistance of the connection portion 200 along the third direction. Thus, the combined use of the first reinforcement portion 310 and the second reinforcement portion 320 can further enhance the stability of the connection between the connection portion 200 and the base 100, thereby ensuring the connection strength of the connection structure.

[0052] Specifically, the number of second reinforcing portions 320 can be two. Along the third direction, one second reinforcing portion 320 is connected to one side of the connecting portion 200, and the other second reinforcing portion 320 is connected to the opposite side of the connecting portion 200. That is, along the third direction, the two second reinforcing portions 320 are symmetrically connected to opposite sides of the connecting portion 200. Along the second direction, the first reinforcing portion 310 is connected to the side of the connecting portion 200 that is away from the notch of the vacant slot 210. The angle between the first reinforcing portion 310 and the second reinforcing portion 320 can be 90°. The combination of the first reinforcing portion 310 and the second reinforcing portion 320 helps further ensure a stable connection between the connecting portion 200 and the base 100.

[0053] refer to Figures 4 to 8 In some embodiments, the connection structure further includes a curved transition portion 330, which is located at the connection between the connection portion 200 and the base 100 and is used to improve the connection stability between the connection portion 200 and the base 100 along the first direction. For example, the curved transition portion 330 is located in the vacant groove 210 and covers the connection portion 200 between the connection portion 200 and the base 100. The curved transition portion 330 may have a rounded structure to reduce stress concentration at the connection between the connection portion 200 and the base 100, making the connection between the connection portion 200 and the base 100 more stable and preventing the connection portion 200 from separating from the base 100 along the first direction.

[0054] Alternatively, the curved transition portion 330 is located outside the vacant groove 210, and the curved transition portion 330 covers the connection between the connecting portion 200 and the base 100, forming a groove at the connection between the connecting portion 200 and the base 100, which is beneficial to improving the pressure distribution during injection molding of the connecting structure and improving the molding quality of the connecting structure.

[0055] Alternatively, the curved transition portion 330 covers the connection between the connecting portion 200 and the base 100 inside the vacant groove 210, and covers the connection between the connecting portion 200 and the base 100 outside the vacant groove 210. Inside the vacant groove 210, a rounded structure is formed by the curved transition portion 330, and outside the vacant groove 210, the curved transition portion 330 located at the connection between the connecting portion 200 and the base 100 forms a curved groove, which is beneficial to further enhance the stability of the connection between the connecting portion 200 and the base 100 and improve the connection strength of the connection structure.

[0056] refer to Figures 1 to 5 In some embodiments, the depth of the connecting hole 220 ranges from 1 mm to 10 mm. By limiting the depth of the connecting hole 220, it is possible to avoid the connection hole 220 being too deep and causing difficulty in tilting and core pulling, and to avoid the connection hole 220 being too deep and affecting the stability of the assembly between the connection hole 220 and the screw or bolt.

[0057] For example, the depth value of the connecting hole 220 can be any value among 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm and 10mm. In particular, the depth value of the connecting hole 220 can be 2.2mm, which is beneficial to better balance the stability of the connection and the difficulty of core pulling.

[0058] In addition, the depth of the connecting hole 220 can also be any value within any value range of 1mm to 2mm, 2mm to 3mm, 3mm to 4mm, 4mm to 5mm, 5mm to 6mm, 6mm to 7mm, 7mm to 8mm, 8mm to 9mm and 9mm to 10mm.

[0059] It should be noted that when the bottom wall of the connecting hole 220 is not perpendicular to the extension direction of the connecting hole 220, and when the bottom wall of the connecting hole 220 is non-planar, the depth of the connecting hole 220 should be understood as the shortest distance from the orifice of the connecting hole 220 to the bottom wall of the connecting hole 220. When the bottom wall of the connecting hole 220 is perpendicular to the extension direction of the connecting hole 220 and the bottom wall of the connecting hole 220 is planar, the distance from the orifice of the connecting hole 220 to the bottom wall of the connecting hole 220 is equal everywhere.

[0060] refer to Figures 1 to 8 In some embodiments, the angle between the extension direction of the connecting hole 220 and the second direction is 1° to 89°, wherein the second direction can be a horizontal direction, and the extension direction of the connecting hole 220 has an angle with the second direction, which is used to ensure that the connecting hole 220 is tilted relative to the horizontal plane, so as to be suitable for situations where an inclined connection is required.

[0061] For example, the angle between the extension direction of the connection hole 220 and the second direction can be 1°, 15°, 30°, 45°, 60°, 75°, 89°, or any angle value in the angle range of 1° to 89°.

[0062] Alternatively, the angle between the extension direction of the connection hole 220 and the second direction may also be an angle interval value with any two angle values ​​from 1°, 15°, 30°, 45°, 60°, 75° and 89° as endpoint values.

[0063] refer to Figures 1 to 8 In some embodiments, the connecting hole 220 includes a first hole segment 221 and a second hole segment 222. The first hole segment 221 and the second hole segment 222 are adjacently arranged and communicated with each other. The first hole segment 221 defines the opening of the connecting hole 220. The aperture of the first hole segment 221 is larger than the aperture of the second hole segment 222, that is, the opening of the connecting hole 220 is larger, which facilitates the demolding of the core pulling, helps to avoid the core pulling from adhering to the edge of the connecting hole 220 at the opening of the connecting hole 220, and also facilitates the screw or bolt to be aligned with the connecting hole 220 for assembly.

[0064] refer to Figures 1 to 8 According to an embodiment of the present application, the electronic device includes a connection structure in any of the above embodiments, and the connection structure is used to realize the connection or fixation between the various components of the electronic device. In particular, it is used to fix components with tilted fixation requirements, or to connect multiple different components at an angle. For example, the electronic device can be a laptop computer, and the laptop computer includes structures such as a shell, a bracket, an interface and a motherboard. The connection structure cooperates with screws or bolts to realize the tilted fixation of a single component, or to realize the tilted connection between multiple components, so as to optimize the layout of the various components inside the laptop computer, and the molding quality of the connection structure is better, and the fixation using the connection structure is more stable, making the laptop computer more reliable.

[0065] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
