[0024] Detailed Description on Embodiments
[0025] Preferred embodiments according to the present application will be described in detail with reference to the accompanying drawings. In the following description, the application is described by taking a portable sound box as an example, but it should be understood that the application can be applied to any electronic equipment, especially small electronic equipment, and there is no limitation here.
[0026] In the following description and the appended claims, directional terms such as "inside" and "outside" are defined, in which "inside" or "inward" should refer to the direction pointing to the inside of the equipment itself or the direction opposite to the external environment, while "outward" or "outside" is the direction opposite to "inward" or "inside" ; "front" refers to the direction in which one component points to the other when two components are mated.
[0027] Fig. 1 is an exploded view showing a quick connector according to the present application. The quick connector 100 basically includes a bracket 110 and a base 120, and the bracket 110 can be fastened to a supported object (not shown) , such as a handlebar of a bicycle, by an appropriate fastening mechanism 200, but the application is not limited to this, and the bracket 110 can be flexible, such as a strap, so as to bind a small electronic equipment to an arm, for example, by the bracket 110 in the form of a strap; In addition, although it is shown in fig. 1 that the fastening mechanism 200 includes a clip to clip on, for example, a handlebar, the application is not limited to this, and other types of fastening mechanisms may be adopted, or the fastening mechanism may be omitted, for example, in the case that the bracket can be self-supporting. The base 120 will be fixed to a small electronic equipment to be supported.
[0028] The bracket 110 is usually formed of plastic or other synthetic materials, and includes a locking head 114, which is integrally made of metal, for example, aluminum alloy, zinc alloy, titanium alloy, stainless steel, etc. However, the application is not limited to the metals listed here, and any material with relatively high hardness and wear resistance can be used, such as synthetic materials. The locking head 114 is fastened to the bracket 110 by, for example, screws, but the present application is not limited to this, and may be fixed to the bracket 110 by welding, riveting, bonding or other fixing methods. For the sake of aesthetics, a decorative plate (not labeled) may be provided to cover the screw position of the locking head 114. As shown in the sectional views of figs. 3A and 3B, the locking head 114 includes a generally cylindrical neck 116 extending outward and a locking part 118 formed at the end of the neck 116, which is generally oval or racetrack-shaped.
[0029] The base 120 is attached to a portable electronic equipment to be supported, such as a portable sound box as shown in Figure 1, so that the portable electronic equipment can be quickly fixed to a support, such as a handle bar of a bicycle, through the engagement between the bracket 110 and the base 120.
[0030] The base 120 includes an outer cover 122, a supporting plate 124 fixedly connected with the outer cover 122, a rotating seat 126 accommodated in the outer cover 122, a rotating plate 128 fixed together with the rotating seat 126 and an spring plate 130 fixed on the portable electronic equipment.
[0031] The outer cover 122 is fixed to the housing of the portable electronic equipment by screws (not shown) , for example, and a cavity is formed on one side facing the rear housing of the portable electronic equipment to accommodate the locking head 114 when the locking head 114 is inserted, which is also called a locking space. In addition, the rear cover 122 also forms a space for accommodating other parts of the locking base 120, such as a rotating seat.
[0032] An opening 123 with a shape corresponding to the shape of the locking part 118, such as a racetrack shape or an oval shape, is formed in the approximate middle position of the outer cover 122 for receiving the locking part 118. The outer cover 122 is molded by plastic material, for example, and the support plate 124 is made of metal, for example, and is fixed to the outer cover 122 at the rear side of the opening 123 by insert mold, for example. However, the present invention is not limited to this, and other materials may be used, and the supporting plate 124 may be fixed to the outer cover 122 by other fixing methods, such as riveting, bonding, clamping, and so on. As will be described below, in the locking process, the support plate 124 will rotate and rub with the locking part 118 and prevent the locking part 118 from droping off, so the support plate 124 needs to be made of a material with high wear resistance and hardness, and preferably metal, such as stainless steel. However, the application is not limited to this, and other materials, such as synthetic materials, can also be used, and the support plate 124 can also be omitted when the strength and wear resistance of the outer cover 122 are sufficient.
[0033] On the inner side of the support plate 124, a rotary seat 126 is provided, which is generally disc-shaped and rotatably accommodated in a cavity formed at the rear side of the outer cover 122. The rotating seat 126 forms an engagement recess (not shown) on the side facing the outer cover 122 or the locking part 118. Preferably, the shape of the recess corresponds to the shape of the locking part 118, for example, so that it can rotate together with the locking part 118 (locking head) when the locking part 118 is inserted. However, the present application is not limited to this, as long as the locking part 118 can cooperate with the locking part 118 after being inserted into the opening 123 of the outer cover 122 so as to rotate together with the locking part 118. Therefore, other engagement structures, such as protrusions, pits and textures, can also be formed on the surface of the rotating seat 126 facing the locking part 118.
[0034] On the inner side of the rotating seat 126 or the side opposite to the engaging recess, a rotating plate 128 is fixed, which is made of metal, especially spring steel, for example, thus giving the rotating plate 128 greater elasticity. And the rotating plate 128 rotates together with the rotating seat 126. As shown in fig. 1, the rotary seat 128 has a plurality of protrusions 129 formed on its inner surface or on the side opposite to the rotary seat 126. As shown in fig. 1, in this embodiment, two protrusions 129 are arranged at an interval of 180 degrees from each other along a circumference, and these protrusions 129 will cooperate with a spring plate 130 described below.
[0035] The spring plate 130 is fixed to the housing of the portable electronic equipment, and is made of metal, especially spring steel. On the spring plate 130, four recesses 132 are arranged at 90 degrees apart from each other on the circumference corresponding to the two protrusions 129 of the rotating plate 126. During the rotation of the rotating plate 126 relative to the spring plate 130, the protrusions 129 on the rotating plate 126 will slide on the surface of the spring plate 130 until a pair of protrusions 129 fall into the corresponding recesses 132, thus providing a temporary positioning function and providing position feedback for users.
[0036] In addition, the spring plate and the rotary plate are formed of spring steel, thereby imparting an outward biasing force to the rotary seat. Thus, when the locking head is not inserted, the rotary seat is biased to the rear side of the opening to close the opening. And the biasing force will eliminate any gap between the locking head and the rear side of the opening during the locking of the locking head.
[0037] Next, the locking process of the quick connector according to the present application will be described with reference to figs. 2 to 5.
[0038] In the unengaged state, the rotating seat 126 abuts against the rear side of the opening or the rear surface of the supporting plate by the bias of the rotating plate and the spring plate, thereby closing the opening 123 and preventing dust and the like from falling into the outer cover 122.
[0039] Referring to fig. 2, fig. 3A and fig. 3B, at the beginning of engagement, the locking part 118 of the engagement head 112 can be inserted from the opening 123 on the outer cover 122, and the rotating seat 126 is pushed inward against the elastic bias of the spring plate and the rotating plate, so that the locking part 118 is located in the locking space inward of the supporting plate 124, and the locking part 118 is fitted into the matching recess outside the rotating seat 126.
[0040] When locking is performed, the small electronic equipment and the bracket are rotated relatively, so that the rear surface of the locking part 118 rotates against the inner surface of the supporting plate 124, and at the same time, the locking part 118 drives the rotating seat 126 to rotate, and the rotation of the rotating seat 126 causes the rotating plate 128 fixed on the rotating seat 126 to rotate against the spring plate 130. Thus, a pair of protrusions 129 of the rotating plate 128 move out of a pair of recesses 132 of the spring plate 130 and rotate against the surface of the spring plate 130. At this time, the bias of the rotating plate 128 and the spring plate 130 biases the rotating seat 126 outward, thereby exerting outward bias on the locking part 118, so that the locking part 118 closely abuts against the supporting plate 124 and rotates relatively.
[0041] When the small electronic equipment or bracket rotates relative to each other by 90 degrees, refer to figs. 4, 5A and 5B, a pair of protrusions 129 of the rotating plate 128 fall into another pair of recesses 132 (a pair of recesses orthogonal to the previous pair) of the spring plate 130, so that the cooperation of the protrusions and recesses provides temporary positioning and position feedback indicating that the locking head has been in the lock position. In this state, as shown in figs. 5A and 5B, with the biasing force provided by the rotating plate and the spring plate, the locking part 118 of the locking head 114 closely abuts against the inner surface of the support plate 124 and the locking head 114 is offset by 90 degrees with respect to the opening 123 of the outer cover 122, preventing the locking part 118 from coming out of the opening 123 of the outer cover 122. Moreover, due to the temporary positioning provided by the protrusions of the rotating plate 128 and the depressions of the spring plate 130, the small electronic equipment will not rotate relative to the bracket even if there is certain vibration or shaking, thereby preventing the small electronic equipment from being detached from the bracket.
[0042] When the user wants to take off the small electronic equipment, the user only needs to rotate the small electronic equipment 90 degrees relative to the bracket, and return to the state shown in fig. 3A and 3B from the state shown in fig. 5A and 5B. At this time, the locking part 114 is shape aligned with the opening 123 of the outer cover 112, so that the locking part 114 can be taken out from the opening 123 of the outer cover 112.
[0043] Therefore, according to the application, a simple and quick connector is provided, which can quickly connect the small electronic equipment with the bracket and support it on other articles, such as bicycle handlebars. Through the elasticity of the spring plate and the rotating plate and the temporary positioning between the spring plate and the rotating plate, the small electronic equipment can be stably supported even under certain shaking or vibration.
[0044] Although the application has been described above with respect to the specific embodiment of the application, the application is not limited to this, and those skilled in the art can make various modifications and improvements on the premise of understanding the essence of the application. These modifications and improvements may include, for example, adopting different materials or similar structures to achieve the same or similar effects, for example, the locking part is not limited to a racetrack shape or an oval shape, But may have any shape whose size in the first direction is smaller than that in the orthogonal direction, and the materials of the components in the above embodiments are not limited to specific materials, but metals, synthetic materials and the like may be selected as required. These modifications and improvements are intended to fall within the scope of this application as set forth in the appended claims.
