[0056] [Example 1]
[0057] Please see Figures 1 to 8 As shown, this is an embodiment of the present invention. Figure 1 and Figure 2 As shown, this embodiment discloses an electronic device comprising a carrier-type fastener 100 and an electronic component 200 mounted on the carrier-type fastener 100. In this embodiment, the electronic component 200 may be a camera (e.g., a dashcam), and the electronic component 200 can be mounted on an object 300 (e.g., the inner surface of a windshield) via the carrier-type fastener 100, but the invention is not limited thereto.
[0058] It should be noted that the load-bearing fastener 100 is described in this embodiment as being used in conjunction with the electronic component 200, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the load-bearing fastener 100 may be used alone (e.g., for sale) or in conjunction with other components.
[0059] In this embodiment, as Figures 3 to 5 As shown, the load-bearing fastener 100 includes a positioning housing 1 and a support frame 2 that can be inserted and fixed to the positioning housing 1 along an insertion / removal direction D1. In addition, for the convenience of explaining the structure of the above components, the support frame 2 (or the load-bearing fastener 100) is further defined with a transverse direction D2 perpendicular to the insertion / removal direction D1, and a thickness direction D3 between the insertion / removal direction D1 and the transverse direction D2.
[0060] More specifically, the outer contour of the positioning housing 1 is generally rectangular and symmetrical, and the positioning housing 1 surrounds and forms a receiving groove S and a through channel 111 (along the thickness direction D3) communicating with the receiving groove S. The receiving groove S has a slot S1 located at one end and communicating with the through channel 111.
[0061] In this embodiment, the receiving groove S includes a first plate-shaped portion 11 and a second plate-shaped portion 12 spaced apart along the thickness direction D3, two side walls 13 facing each other along the transverse direction D2, and an end wall 14. The first plate-shaped portion 11 is divided into two pieces by forming a through channel 111, and the outer surface of the second plate-shaped portion 12 (or positioning housing 1) has a mating surface 121 located on the opposite side of the through channel 111, so that the positioning housing 1 can be adhered to the object 300 by the mating surface 121.
[0062] Furthermore, each of the two sidewalls 13 has a locking hole 131 and a rib 132 away from the locking hole 131; that is, each locking hole 131 and the corresponding rib 132 are located at opposite ends of the sidewall 13 along the insertion / removal direction D1, each locking hole 131 is adjacent to the slot S1 and has a hole wall 1311 adjacent to the slot S1, while each rib 132 is away from the slot S1.
[0063] In this embodiment, the two engaging holes 131 are arranged along the transverse direction D2, and each engaging hole 131 is through-hole along the transverse direction D2.
[0064] Additionally, the end wall 14 is located on the opposite side of the slot S1, and the end wall 14 is connected to one end of the first plate-shaped portion 11, one end of the second plate-shaped portion 12, and one end of each side wall 13. The end wall 14 is separated from any hole wall 1311 by a configuration distance L1 along the insertion / removal direction D1.
[0065] It should be noted that, in this embodiment, the support frame 2 is a single-piece sheet structure integrally formed and is described in conjunction with the positioning housing 1, but the present invention is not limited thereto. For example, in other embodiments of the present invention not illustrated, the support frame 2 can be used alone (e.g., for sale) or in conjunction with other components.
[0066] In this embodiment, the support frame 2 is inserted into and fixed within the receiving groove S of the positioning housing 1 from the slot S1 along the insertion / removal direction D1. The support frame 2 includes a body segment 21, and supports are respectively positioned from opposite sides of the body segment 21 (e.g., ...). Figure 5 The two holding arms 22 are formed by extending from the upper and lower sides of the body segment 21, and an elastic structure 23 is formed by extending from the body segment 21.
[0067] At least a portion of the body segment 21 is exposed outside the positioning housing 1 through the through channel 111, so that a portion of the electronic component 200 is located in the through channel 111 and fixed to the body segment 21 (e.g.: Figure 1 This allows the electronic component 200 to be positioned at a predetermined location via the positioning housing 1. In other words, the electronic component 200 can separate from the positioning housing 1 along the insertion / removal direction D1, together with the support frame 2 to which it is fixed.
[0068] More specifically, such as Figures 3 to 5 As shown, the body segment 21 includes a front end portion 211 and a rear end portion 212 connected to the front end portion 211 along the insertion / removal direction D1, and the end of the rear end portion 212 is closed by a slot S1. The outer surface of the body segment 21 has a top surface 213 and a bottom surface 214 located on opposite sides. The body segment 21 has a plurality of mating grooves 2131 arranged along the transverse direction D2 on the top surface 213, and the plurality of mating grooves 2131 are located at the front end portion 211. The body segment 21 has a patterned reinforcing rib 2141 on the bottom surface 214.
[0069] In this embodiment, the body segment 21 is described with multiple engagement grooves 2131 formed at the front end 211, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the number of engagement grooves 2131 may be at least one, and the position of at least one engagement groove 2131 may be located at at least one of the front end 211 and the rear end 212, depending on design requirements.
[0070] In addition, such as Figure 1 As shown, in this embodiment, the electronic component 200 is fixed to the front end 211 of the support frame 2 and installed (e.g., inserted and glued) in at least one connecting groove 2131, so that the electronic component 200 can be stably connected to the support frame 2.
[0071] like Figures 3 to 5 As shown, the two holding arms 22 are located on opposite sides of the rear end 212 (e.g.: Figure 5 The two retaining arms 22 are located within two engaging holes 131, and each retaining arm 22 is connected at one end to the junction of the front end 211 and the rear end 212, while the other end of each retaining arm 22 is a free end and is defined as an abutment end 221. Furthermore, the two retaining arms 22 are respectively located within two engaging holes 131, and the two retaining arms 22 can elastically swing (towards the rear end 212) under the pressure of the two side walls 13 in the lateral direction D2.
[0072] Furthermore, the elastic structure 23 is elastically deformed by the receiving groove S under the pressure in the insertion / removal direction D1, so that the abutting end 221 of each holding arm 22 generates a displacement sufficient to abut against the positioning housing 1 in the insertion / removal direction D1 (e.g., the abutting end 221 abuts against the hole wall 1311 of the corresponding engaging hole 131 due to the displacement), thereby ensuring that there is no gap between the support frame 2 and the positioning housing 1 in the insertion / removal direction D1, thus effectively preventing the support frame 2 and the positioning housing 1 from colliding with each other and generating abnormal noise in the insertion / removal direction D1.
[0073] It should be noted that the specific shape of the elastic structure 23 can be adjusted and varied according to design requirements, and in order to ensure that each abutting end 221 can stably abut against the corresponding hole wall 1311, the elastic structure 23 preferably has at least a portion of the following structural conditions, but the present invention is not limited thereto.
[0074] In this embodiment, the elastic structure 23 is connected to the front end portion 211 and includes a terminal elastic arm 231 and two side elastic arms 232, with the terminal elastic arm 231 and the two side elastic arms 232 spaced apart from each other. The terminal elastic arm 231 is positioned away from the slot S1 and connected to the edge of the front end portion 211 away from the rear end portion 212 (e.g., ...). Figure 5 The leading edge of the front end 211 is used to make the end spring arm 231 and the body section 21 together surround and form a closed space.
[0075] Furthermore, the maximum distance L2 between the end spring arm 231 and the abutting end 221 of any of the holding arms 22 along the insertion / removal direction D1 is greater than the arrangement distance L1. Accordingly, the end spring arm 231 can elastically deform under the pressure of the end wall 14 of the receiving groove S in the insertion / removal direction D1, so as to facilitate the displacement of the abutting end 221 of each holding arm 22 in the insertion / removal direction D1.
[0076] Furthermore, the two side spring arms 232 are respectively connected to opposite sides of the main body section 21 and are adjacent to the two retaining arms 22. That is, each side spring arm 232 and its adjacent retaining arm 22 are arranged along the insertion / removal direction D1. Moreover, in this embodiment, the two side spring arms 232 are connected to the front end section 211 so that each side spring arm 232 and the main body section 21 together form a closed space.
[0077] Among them, the two side spring arms 232 can be elastically deformed by the pressure of the two ribs 132 in the insertion and extraction direction D1, so as to facilitate the displacement of the abutting end 221 of each holding arm 22 in the insertion and extraction direction D1. Furthermore, the two side spring arms 232 can be elastically deformed by the pressure of the two side walls 13 in the lateral direction D2, so as to effectively prevent the front end 211 from swinging relative to either side wall 13.
[0078] Furthermore, the elastic structure 23 in this embodiment Figures 1 to 7 Although the description uses one end spring arm 231 and two side spring arms 232 to jointly enable the abutment end 221 of each holding arm 22 to displace along the insertion / removal direction D1, the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the elastic structure 23 may use only the end spring arm 231, or only the two side spring arms 232; or, as... Figure 8 As shown, the elastic structure 23 can be a single elastic arm that surrounds the entire outer side of the front end portion 211 (that is, the elastic structure 23 can cover as follows). Figure 5 The area where the end spring arm 231 and the two side spring arms 232 are located is shown.
[0079] [Example 2]
[0080] Please see Figure 9 and Figure 10 As shown, this is Embodiment Two of the present invention. Since this embodiment is similar to Embodiment One described above, the similarities between the two embodiments will not be repeated. The differences between this embodiment and Embodiment One are roughly explained as follows:
[0081] In this embodiment, as Figure 9As shown, the elastic structure 23 can form two end spring arms 231, which are arranged in a mirror-symmetric configuration. One end of each end spring arm 231 is connected to the body segment 21 (e.g., the front end 211), while the other end is a free end (i.e., the front end 211 not connected to the body segment 21), and the free ends of the two end spring arms 231 are adjacent to each other and face each other. Furthermore, the free end of any end spring arm 231 can be spaced at a maximum distance L2 along the insertion / removal direction D1 from the abutting end 221 of any holding arm 22.
[0082] Furthermore, such as Figure 10 As shown, one end of each side spring arm 232 is connected to the body segment 21 and adjacent to an end spring arm 231, while the other end of each side spring arm 232 is a free end and adjacent to a holding arm 22. That is, the free end of each side spring arm 232 is adjacent to but not connected to the front end 211 of the body segment 21.
[0083] Furthermore, the elastic structure 23 in this embodiment Figure 9 and Figure 10 The present invention is illustrated by the structure shown, but is not limited thereto. For example, in other embodiments not shown in the present invention, the elastic structure 23 may employ only at least one end spring arm 231 or only two side spring arms 232; or, the end spring arms 231 and side spring arms 232 disclosed in Embodiments 1 and 2 may be used in combination.
[0084] [Technical Effects of the Embodiments of the Invention]
[0085] In summary, the electronic device and the load-bearing fastener and its support frame disclosed in the embodiments of the present invention can, through the elastic deformation of the elastic structure in the insertion and removal direction, enable the abutting end of each fastening arm to generate displacement or abut against the wall of the corresponding engaging hole, thereby ensuring that there is no gap between the support frame and the positioning housing in the insertion and removal direction, thus effectively preventing the support frame and the positioning housing from colliding with each other and generating abnormal noise in the insertion and removal direction.
[0086] Furthermore, the support frame disclosed in the embodiments of the present invention can present the elastic structure in the form of spring arms, so as to facilitate adjustment and variation according to design requirements (e.g., the construction of at least one end spring arm and two side spring arms can be selectively used and can be matched with each other), and can also make each abutting end stably abut against the corresponding hole wall.
