Description

Technical Field

[0001] This utility model relates to the field of clamping technology for electronic devices such as mobile phones and tablets, and in particular to an electronic device clamping mechanism and a heat dissipation back clip. Background Technology

[0002] Clamping mechanisms for electronic devices such as mobile phones and tablets have numerous applications, including selfie sticks, handheld stabilizers, camera tripods, and mobile phone / tablet heat sinks. Existing electronic device clamping mechanisms (such as mobile phone clamps and tablet clamps) are often designed with elastically extendable structures to hold different electronic devices. These elastically extendable structures can generally be categorized into pull-rod type and slider type.

[0003] A lever-type elastic telescopic structure, such as the patent document published on January 21, 2015, with publication number CN204119349U, entitled "An Integrated Selfie Device," discloses that by compressing a spring through a lever (movable rod), the clamping mechanism extends outward to form an elastic clamping space. A slider-type elastic telescopic structure, such as the patent document published on March 11, 2022, with publication number CN216017552U, entitled "A Heat Dissipation Back Clip and Electronic System," discloses that by cooperating with a sliding part and an elastic element, the clamping part has a clamping force, and discloses that a first limiting element protrudes from the sliding part and a second limiting element protrudes from the cover, and the sliding part is limited by the cooperation of the two limiting elements.

[0004] In the existing technology, the elastic telescopic structure of the pull rod type is relatively complex and the assembly is time-consuming and labor-intensive; while the elastic telescopic structure of the slider type, the limiting part is often a small boss integrally formed from the sliding part and / or the cover (shell). After the small boss is formed, it is easy to break during long-term use, which will cause the entire sliding part or shell to be scrapped. Moreover, the small boss formed by one piece has a high defect rate and is also easy to be damaged during assembly and testing. Utility Model Content

[0007] Optionally, the housing includes a back shell and a cover shell that overlap each other, and the back shell and the cover shell form the receiving cavity when they are closed. The limiting groove is disposed on the back shell, and the limiting member is detachably disposed on the sliding part.

[0008] Optionally, the limiting groove is disposed on the side of the back shell facing the receiving cavity, or the limiting groove extends through the back shell.

[0009] Optionally, the back cover has a through mounting hole, which is located at the end of the limiting groove, and the mounting hole allows the limiting member to be inserted into the limiting groove.

[0010] Optionally, the mounting hole is located at the end of the limiting groove near the center of the housing.

[0011] Optionally, the limiting member is one or more of screws, bolts, and bolts, and the sliding part has a mounting position for installing the limiting member.

[0012] Optionally, the two clamping parts are rotatably connected to their corresponding sliding parts. Each of the two clamping parts is provided with a notch, and the housing is provided with a flange that matches the notch. After the two clamping parts are rotated relative to their corresponding sliding parts, they can be folded to the flange.

[0013] Optionally, the clamping assembly further includes an elastic element, the two ends of which are respectively fixed to the two sliding portions.

[0014] Optionally, the clamping assembly further includes two sets of elastic elements, each of which corresponds to one of the two sliding portions. One end of each elastic element is connected to its corresponding sliding portion, and the other end of each elastic element is connected to the housing.

[0015] This utility model also discloses a heat dissipation back clip, including heat dissipation fins and a cooling fan, as well as an electronic device clamping mechanism as described above.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] like Figures 1 to 7 As shown, this embodiment of the present invention provides an electronic device clamping mechanism, including a housing 10, the housing 10 having an internal receiving cavity (not shown in the figure, but all the internal space of the housing 10 is within the receiving cavity), and sliding channels 101 communicating with the receiving cavity are opened on opposite sides of the housing 10; it also includes a clamping assembly 20, the clamping assembly 20 including two clamping members 21 slidably disposed on the housing 10, each clamping member 21 including a clamping part 211 and a sliding part 212, the two sliding parts 212 corresponding one-to-one with the two sliding channels 101. One end of each of the two sliding parts 212 is slidably disposed in the receiving cavity, and the other end of each of the two sliding parts 212 can slide out of the receiving cavity through their corresponding sliding channels 101. Two clamping parts 211 correspond one-to-one with the two sliding parts 212. The two clamping parts 211 are connected to their corresponding sliding parts 212 outside the receiving cavity. One of the housing 10 and the sliding parts 212 is provided with a limiting member 30, and the other is provided with a limiting groove 121 that cooperates with the limiting member 30. The limiting member 30 is detachably connected to the sliding part 212 or the limiting member 30 is detachably connected to the housing 10.

[0035] like Figures 1 to 4As shown, the other ends of the two sliding parts 212 can slide out of the receiving cavity through their corresponding sliding channels 101, that is, the sliding parts 212 can slide towards the outside of the housing 10. The two clamping parts 211 are connected to their corresponding sliding parts 212 outside the receiving cavity, so that the two sliding parts 212 can drive the clamping parts 211 to slide towards the outside of the housing 10 respectively. In this way, the travel of the clamping space between the two clamping parts 211 can be controlled by the sliding of the sliding parts 212, which makes it convenient to clamp electronic devices of different sizes between the two clamping parts 211.

[0036] One of the housing 10 and the sliding part 212 is provided with a limiting member 30, and the other is provided with a limiting groove 121 that cooperates with the limiting member 30. There are two implementation methods: one is to provide the limiting member 30 on the housing 10, and in this case, the limiting groove 121 is provided on the sliding part 212; the other is to provide the limiting groove 121 on the housing 10, and in this case, the limiting member 30 is provided on the sliding part 212. Through the cooperation of the limiting member 30 and the limiting groove 121, the limiting member 30 slides within the limiting groove 121, preventing the limiting member 30 from disengaging from the limiting groove 121. Since the limiting member 30 is provided on either the housing 10 or the sliding part 212, the sliding stroke of the sliding part 212 relative to the housing 10 is limited by the sliding of the limiting member 30 within the limiting groove 121, and the sliding strokes of both are the same.

[0037] The limiting member 30 is detachably mounted on the sliding part 212 or the housing 10, allowing it to be manufactured or procured separately. Compared to the existing technology where the limiting member is a small boss integrally formed from the sliding part and / or housing, the limiting member 30 can be made of a higher-strength component as needed. Even if the limiting member 30 in this embodiment is damaged during long-term use, it can be directly replaced without scrapping the entire sliding part 212 or housing 10. Moreover, in the prior art, the limiting member (small boss) is very small in size compared to the sliding part and housing, resulting in a high defect rate during integral molding and easy damage during assembly and testing.

[0038] See Figures 1 to 5 The housing 10 includes a back shell 12 and a cover shell 1310 that overlap each other, forming a receiving cavity when closed. A limiting groove 121 is provided on the back shell 12, and a limiting member 30 is detachably provided on the sliding portion 212. Thus, the overlapping back shell 12 and cover shell 1310 facilitate the installation and removal of the limiting member 30 and the sliding portion 212 within the receiving cavity. The limiting member 30 is detachably provided on the sliding portion 212 rather than on the housing 10, thereby preventing the housing 10 from becoming too thick and affecting the installation of other functional components.

[0039] See Figure 2 and Figure 3The limiting groove 121 is disposed on the side of the back shell 12 facing the receiving cavity, or the limiting groove 121 penetrates the back shell 12. A mounting hole 122 is provided on the back shell 12, penetrating the back shell 12. The mounting hole 122 is located at the end of the limiting groove 121, allowing the limiting member 30 to be inserted into the limiting groove 121. Thus, the limiting member 30 can be inserted from the outside of the back shell 12 through the mounting hole 122. The mounting hole 122 is located at the end of the limiting groove 121 near the center of the housing 10. When the limiting member 30 slides to this end, the sliding part 212 is in its initial state, that is, the sliding part 212 has not yet slid out of the limiting groove 121 towards the back housing 12. At this time, it is more convenient to install or remove the limiting member 30 from the mounting hole 122. There is no need to worry that after the sliding part 212 slides out of the back housing 12 a large distance, the other end of the sliding part 212 will be suspended, making it difficult to position the mounting hole 122 and the sliding part 212. Or, when the elastic member 22 is installed on the sliding part 212, the sliding part 212 has an inward restoring force after sliding out of the back housing 12. If the mounting hole 122 is located at the end of the limiting groove 121 away from the center of the housing 10, the installation of the limiting member 30 at this location requires overcoming the elastic potential energy generated by the elastic member 22, making it inconvenient to position the mounting hole 122 and the sliding part 212.

[0040] See Figure 4 The limiting component 30 can be one or more of screws, bolts, and nutes. The sliding part 212 has a mounting position 2121 for installing the limiting component 30. Screws, bolts, and nutes are common detachable fasteners, allowing for easy removal and installation of the limiting component 30 at the mounting position 2121. The mounting position 2121 can be configured with screw holes, bolt holes, etc., depending on the specific requirements. Because multiple limiting components 30 can be used, they can all be screws, bolts, or nutes for convenient and standardized assembly. Alternatively, the limiting component 30 can be multiple types of screws, bolts, or nutes, as long as the detachable structure of the limiting component 30 and the mounting position 2121 is achieved.

[0041] See Figure 1 , Figure 4 and Figure 5 Two clamping parts 211 are rotatably connected to their corresponding sliding parts 212. Each clamping part 211 has a notch 2111, and the housing 10 has a flange 102 that matches the notch 2111. After rotating relative to their corresponding sliding parts 212, the two clamping parts 211 can be folded into the flange 102. Thus, through the cooperation of the notch 2111 and the flange 102, when the two clamping parts 211 are not used to clamp the electronic device, they can be rotated and folded into the flange 102, thereby facilitating the storage and carrying of the entire device.

[0042] In one embodiment (not shown in the figures of this embodiment), the clamping assembly 20 further includes an elastic element 22, with its two ends respectively fixed to two sliding portions 212. Thus, the two sliding portions 212 are connected by the elastic element 22. When the two sliding portions 212 slide outward relative to the housing 10, the elastic element 22 is stretched, causing it to accumulate elastic potential energy. This results in the two sliding portions 212 having a force that slides towards the housing 10, thereby forming an elastic clamping space between the two clamping portions 211.

[0043] See Figures 4 to 7 The clamping assembly 20 also includes two sets of elastic elements 22, each corresponding to one of the two sliding portions 212. One end of the elastic element 22 is connected to its corresponding sliding portion 212, and the other end of the elastic element 22 is connected to the housing 10. Figure 4 A set of elastic elements 22 includes two springs. The two springs can be connected to the sliding part 212 and the housing 10 respectively according to the actual situation. The method of fixing the springs is not limited here. For example, a connecting post 123 can be protruded from the housing 10 in the direction of the receiving cavity, and the spring can be sleeved or fixed on the connecting post 123. The connection method between the spring and the sliding part 212 is similar and will not be described in detail here.

[0044] This utility model embodiment also provides a heat dissipation back clip, including heat dissipation fins 40 and a heat dissipation fan 50, as well as the electronic device clamping mechanism described above. The heat dissipation fins 40 are disposed in the receiving cavity, and two oppositely disposed sliding grooves 401 are provided on one side of the heat dissipation fins 40. Two sliding parts 212 correspond one-to-one with the two sliding grooves 401, and the two sliding parts 212 slide in their corresponding sliding grooves 401 and slide out of the receiving cavity through their corresponding sliding channels 101. Multiple heat dissipation fins 402 are disposed on the other side of the heat dissipation fins 40, and the heat dissipation fan 50 is disposed on the heat dissipation fins 40, and the multiple heat dissipation fins 402 are arranged around the heat dissipation fan 50.

[0045] See Figure 2 and Figure 8 By providing two opposing sliding grooves 401 on one side of the heat sink 40, and allowing two sliding parts 212 to slide within their corresponding sliding grooves 401, the provision of the sliding parts 212 does not excessively increase the thickness of the entire heat sink back clip. Furthermore, by providing receiving grooves on opposite sides of the heat sink 40, the heat sink's heat dissipation efficiency is not excessively reduced.

[0046] In one embodiment, the housing 10 is further provided with a magnetic suction member 60, which is used for magnetic adsorption with the electronic device. Thus, the heat dissipation back clip can be fixed to the electronic device by magnetic attraction and / or clamping by the clamping assembly 20.

Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
