[0036] It should also be understood that although "first" or "second" etc. are used in this specification to indicate certain features, they are only used to indicate the functions and are not intended to limit the number and importance of specific features.
[0037] Currently, most of the waterproof structures on the market use the design of upper and lower extruded waterproof rings and / or side extruded waterproof rings to achieve the waterproof effect.
[0038] However, traditional waterproof structures occupy a large space, which is not conducive to product miniaturization; and traditional waterproof structures are difficult to assemble, resulting in low installation efficiency.
[0039] Based on this, the present application provides a sealing structure and a charging device, which requires a small area, is conducive to miniaturization of the product, and has simple and easy assembly steps, and has high installation efficiency. The details will be described in the subsequent embodiments.
[0040] See also Figure 1 According to some embodiments, the sealing structure may specifically include a lower shell 100 , an upper pressure plate 200 and an elastic insert 300 .
[0041] See also Figure 2 The lower shell 100 may be provided with a first arc-shaped opening 101, and sealing slots 102 are provided at both ends of the first arc-shaped opening 101. The upper pressing plate 200 is provided above the elastic insert 300, and can be used to apply a downward force to the elastic insert 300 so that the elastic insert 300 is inserted into the sealing slot 102.
[0042] See also Figure 3 The elastic insert 300 is provided with a second arc opening 301. When the elastic insert 300 is inserted into the sealing slot 102 under the action of the upper pressing plate 200, the first arc opening 101 can cooperate with the second arc opening 301 to form a mounting hole, and the mounting hole can be used to install the sealing plug 400.
[0043] The sealing structure provided in the above embodiment includes a lower shell 100, an upper pressing plate 200 and an elastic insert 300. The lower shell 100 is provided with a first arc-shaped opening 101, and sealing slots 102 are provided at both ends of the first arc-shaped opening 101.
[0044] By adopting the above-mentioned sealing structure, the elastic insert 300 can be inserted into the sealing slot 102 through the upper pressure plate 200, so that the second arc-shaped opening 301 can cooperate with the first arc-shaped opening 101 to form a mounting hole for installing the sealing plug 400. At this time, the elastic insert 300 is embedded in the sealing slot 102, and an extrusion force is generated between the two, thereby forming a good liquid-tight seal between the sealing plug 400 and the mounting hole, effectively preventing liquid from entering the interior of the product from the outside.
[0045] In the above sealing structure, since the elastic insert 300 is embedded in the sealing slot 102, the sealing structure requires a small area, which helps to save the internal space of the product, thus facilitating the realization of a delicate and compact product. In addition, the operation steps of inserting the elastic insert 300 into the sealing slot 102 are simple and easy to implement, so it is also easy to install and can have a high installation efficiency.
[0046] As an example, Figure 3 As shown, the elastic insert 300 may be provided with a rib 311 for inserting into the sealing slot 102. The rib 311 may cooperate with the sealing slot 102 to form an extrusion seal and achieve a good sealing effect.
[0047] In some embodiments, the thickness of the rib 311 may gradually increase from bottom to top. In other words, the cross-section of the rib 311 may be trapezoidal. Figure 3 In the elastic insert 300 shown, the thickness of the rib 311 at a is greater than the thickness at b.
[0048] When the sealing structure provided by the above embodiment is used for sealing, when the elastic insert 300 is initially inserted into the sealing slot 102, no squeezing force is formed between the two, which facilitates the continued insertion of the elastic insert 300; when the elastic insert 300 is about to be inserted to the bottom, a squeezing force can be formed between the two, thereby forming a squeezing seal and achieving a good sealing effect. Therefore, the thickness of the rib 311 is set to gradually increase from bottom to top, which helps to make the sealing structure easier to assemble.
[0049] Please continue reading Figure 3 In some embodiments, the elastic insert 300 may include a front baffle 312 and a rear baffle 313 of the same shape. In this case, the rib 311 should be disposed between the front baffle 312 and the rear baffle 313 .
[0050] As an example, Figure 3 As shown, the width of the front baffle 312 and the width of the rear baffle 313 may gradually increase from bottom to top.
[0051] Please continue reading Figure 3 In some embodiments, the front baffle plate 312, the rear baffle plate 313 and the rib position 311 can be integrally provided. In other words, the front baffle plate 312, the rear baffle plate 313 and the rib position 311 can be an integrally formed structure.
[0052] Please combine Figure 4 It is understood that in some embodiments, when the elastic insert 300 is inserted into the sealing slot 102 , the top edge of the elastic insert 300 may be flush with the top edge of the lower housing 100 .
[0053] The embodiment of the present application does not specifically limit the selection of the elastic insert 300. In some embodiments, the elastic insert 300 may include but is not limited to a silicone insert.
[0054] The present embodiment of the application does not specifically limit the selection of the lower housing 100. In some embodiments, the lower housing 100 may include but is not limited to a plastic shell.
[0055] In some embodiments, a sealing strip 314 may be provided at the bottom of the elastic insert 300 and / or at the contact surface between the sealing slot 102 and the bottom of the elastic insert 300 .
[0056] For example Figure 2 As shown, a sealing strip 314 may be provided at the contact surface c between the sealing slot 102 and the bottom of the elastic insert 300. Figure 3 As shown, a sealing strip 314 is provided at the bottom of the elastic insert 300 .
[0057] On the other hand, some embodiments of the present application further provide a charging device. The charging device may specifically include the sealing structure provided in some of the above embodiments. The technical effects that can be achieved by the aforementioned sealing structure can also be achieved by the charging device, which will not be described in detail here.
[0058] Please continue reading Figure 1 The charging device also includes a sealing plug 400 installed in the mounting hole in the sealing structure.
[0059] In some embodiments, the charging device may further include an upper shell, which may be pressed and matched with the lower shell 100 in the sealing structure to form a housing of the charging device.
[0060] It should be noted that in the charging device provided in the above embodiment, the upper housing can be used as the upper pressing plate 200 in the aforementioned sealing structure. Figure 4 shown.
[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features of the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0062] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
