Description

Technical Field

[0001] The present invention relates to an expansion device, and more particularly to an expansion device capable of holding an electronic device. Background Technology

[0002] With the development of the mobile gaming and esports industry, gaming phones and related peripherals have gradually become popular in the consumer market. For example, to provide a better operating experience, an extended gaming controller can be connected to a mobile phone as an input interface. Extended gaming controllers are generally designed based on the shape and size of the corresponding mobile phone to ensure a good fit. However, a high percentage of consumers use protective cases to cover their phones, so the protective case must be removed before the phone can be successfully installed on the extended gaming controller, causing inconvenience in its use. In addition, current extended gaming controllers do not fit securely with mobile phones, and the user's gaming experience is easily reduced due to the controller becoming loose. Furthermore, repeated plugging and unplugging of the extended gaming controller connector can easily damage the connector and / or the mobile phone. Summary of the Invention

[0101] Figure 1 This is a front view of an expansion device according to an embodiment of the present invention. Figure 2 Draw Figure 1 The expansion device is integrated into the electronic device. Please refer to... Figure 1 and Figure 2 In this embodiment, the expansion device 100 is, for example, an expandable game controller, used to connect an electronic device 50, such as a smartphone. The expansion device 100 includes a device body 110 and two clamping structures 120. The device body 110 includes two support structures 112A and 112B, and the two clamping structures 120 are respectively disposed on the two support structures 112A and 112B. Each support structure 112A and 112B has a support portion 1121 and a clamping portion 1122. The support portion 1121 is used to support the electronic device 50. The two clamping portions 1122 are, for example, a pair of game controller components or their housings, used to clamp the electronic device 50 along a first axis X. Each clamping structure 120 is used to clamp the electronic device 50 together with the support portion 1121 along a second axis Z perpendicular to the first axis X.

[0102] The following describes the specific manner in which the clamping part 1122 clamps the electronic device 50 in the first axis X.

[0103] Figure 3 Draw Figure 1 The two load-bearing structures slide relative to each other. Figures 4A to 4D yes Figure 3 The flowchart of the main body of the device. Figure 6 yes Figure 4C A side view of the support section carrying the electronic device. Figure 7 Draw Figure 6 The clamping part clamps the electronic device. In this embodiment, the two supporting structures 112A and 112B are slidably arranged relative to each other along the first axis X, and the device body 110 is as follows: Figure 4AThe diagram shows at least one first elastic element 114 (two are shown) and a positioning assembly 116. The first elastic element 114 is, for example, a compression spring and is connected between two load-bearing structures 112A and 112B. The positioning assembly 116 is movably disposed on the load-bearing structure 112A.

[0104] When the expansion device 100 is in Figure 1 In the indicated state, the positioning component 116 can be as follows: Figure 4A The positioning support structure 112B is shown. When the positioning component 116 is as shown... Figure 4B When the positioning of the load-bearing structure 112B is released, the two load-bearing structures 112A and 112B can be released from the position by the elastic force of the first elastic element 114. Figure 1 and Figure 4B The first state shown is relatively slid to Figure 3 and Figure 4C The second state is shown. In the second state, the distance between the two clamping portions 1122 is greater than the distance between the two clamping portions 1122 in the first state. In the second state, the user can... Figure 6 The electronic device 50 is placed on two support portions 1121 as shown. The positioning assembly 116 can resist the elastic force of the first elastic member 114. Figure 4D As shown, the supporting structure 112B is positioned between the first state and the second state, so that the two clamping parts 1122 can be positioned as follows: Figure 7 The electronic device 50 is shown clamped between the first state and the second state. When the positioning component 116 releases its positioning of the support structure 112B, the two support structures 112A and 112B can be reset by the elastic force of the first elastic member 114. Figure 6 The second state shown allows the two clamping parts 1122 to release the electronic device 50.

[0105] The following describes the specific manner in which the clamping structure 120 clamps the electronic device 50 along the second axis Z.

[0106] Figure 8 yes Figure 1 A partial perspective view of the expansion device. Figure 9A and Figure 9B yes Figure 8 The flowchart of the clamping structure's operation. Figure 10 yes Figure 9B A side view of the support section carrying the electronic device. Figure 11A Draw Figure 10 The clamping part clamps the electronic device. The clamping structure 120 of this embodiment is as follows: Figure 8The diagram shows a clamping member 122, at least one second elastic member 124 and at least one second elastic member 126 (shown as a plurality of second elastic members 124 and a plurality of second elastic members 126), and at least one pushing assembly 128 (shown as two). The clamping member 122 is movably disposed within the clamping portion 1122 of the bearing structure 112A along a second axis Z, and the clamping portion 1122 and the bearing portion 1121 are movably connected to each other along the second axis Z. The second elastic member 124 is, for example, a compression spring and is connected between the clamping member 122 and the clamping portion 1122 of the bearing structure 112A, and the second elastic member 126 is, for example, a compression spring and is connected between the clamping portion 1122 and the bearing portion 1121. The pushing assembly 128 is movably disposed within the clamping portion 1122 of the bearing structure 112A.

[0107] The pushing assembly 128 can resist the elastic force of the second elastic members 124 and 126 and, relative to the clamping part 1122, pull the clamping member 122 and the supporting part 1121 from... Figure 9A The second position shown Figure 9B The first position is shown. The distance between the clamping member 122 and the support portion 1121 in the first position is greater than the distance between the clamping member 122 and the support portion 1121 in the second position. The user can press the pushing assembly 128 to position the clamping member 122 and the support portion 1121 in the first position, such as... Figure 10 As shown, this creates sufficient distance between the clamping member 122 and the support portion 1121, allowing the user to place the electronic device 50 on the support portion 1121. Next, the user can release the pushing assembly 128 to move the clamping member 122 and the support portion 1121 from the first position to the second position due to the elastic force of the second elastic members 124 and 126, thereby allowing the clamping member 122 to... Figure 11A As shown, the electronic device 50 is clamped together with the support portion 1121 by the elastic force of the second elastic members 124 and 126 between the first position and the second position.

[0108] As described above, the two support structures 112A and 112B of the expansion device 100 in this embodiment can slide relative to each other from a first state to a second state along the first axial direction X as the elastic potential energy of the first elastic member 114 changes. Thus, the two support structures 112A and 112B can be adjusted to a suitable state between the first and second states according to the dimensions of the electronic device 50 along the first axial direction X, thereby clamping the electronic device 50 along the first axial direction X by means of their clamping portion 1122. Furthermore, the clamping member 122 of the expansion device 100 in this embodiment can move from a first position to a second position along the second axial direction Z as the elastic potential energy of the second elastic member 124 changes. Thus, the clamping member 122 can be adjusted to a suitable position between the first and second positions according to the dimensions of the electronic device 50 along the second axial direction Z, thereby clamping the electronic device 50 along the second axial direction Z. Accordingly, the expansion device 100 of this embodiment can be securely attached to the electronic device 50 regardless of its size.

[0109] Figure 11B Draw Figure 11A The expansion device is integrated into the electronic device, which is fitted with a protective casing. For example, when the electronic device 50... Figure 11B When the protective shell 52 is installed, increasing the dimensions in the first axis X and the second axis Z, the clamping part 1122 and the clamping member 122 can smoothly clamp the protective shell 52 of the electronic device 50 through the aforementioned position and state adjustments.

[0110] The following further describes the detailed configuration and operation of the positioning component 116 of the device body 110 in this embodiment.

[0111] Please refer to Figure 4A In this embodiment, the positioning component 116 includes a push button 1161, two positioning members 1162, a third elastic member 1163, and a fourth elastic member 1164. The push button 1161 is slidably disposed on the support portion 1121 of the support structure 112A along a first axial direction X, and is configured to move along a first direction D1 by the force applied by the user. In this embodiment, the positioning component 116 is disposed on the support structure 112A, and the first direction D1 is the direction of the support structure 112A away from the support structure 112B. The positioning members 1162 are slidably disposed on the support portion 1121 of the support structure 112A along a third axial direction Y. The third elastic member 1163 is, for example, a compression spring and is connected between the two positioning members 1162. The fourth elastic member 1164 is, for example, a compression spring and is connected between the push button 1161 and the support portion 1121 of the support structure 112A.

[0112] The two positioning elements 1162 can be adjusted by the elastic force of the third elastic element 1163. Figure 4A or Figure 4DThe positioning support structure 112B shown has a support portion 1121. Specifically, each positioning member 1162 has a first rack portion 1162a, and the support portion 1121 of the support structure 112B has a second rack portion 1121a. The first rack portion 1162a and the second rack portion 1121a are adapted to mesh with each other to position the support portion 1121 of the support structure 112B.

[0113] Figure 5 yes Figure 4A Enlarged views of the first and second rack sections are shown below. Please refer to the following: Figure 5 More specifically, each tooth T1 of the first rack portion 1162a has a first stop surface S1 and a first guide slope S2, and each tooth T2 of the second rack portion 1121a has a second stop surface S3 and a second guide slope S4. The first stop surface S1 and the second stop surface S3 face each other and prevent the bearing structure 112B from moving in the first direction D1 toward the first state. The first guide slope S2 and the second guide slope S4 face each other. When the user applies force to the bearing structure 112B in the first direction D1, the bearing structure 112B can move in the first direction D1 to the appropriate position to clamp the electronic device 50 by being guided by the first guide slope S2 and the second guide slope S4 and by slight elastic deformation of the structure.

[0114] On the other hand, the push button 1161 can be activated by the user's force. Figure 4B The elastic force resisting the fourth elastic element 1164 moves along the first direction D1, causing the two positioning elements 1162 to move closer to each other along a direction parallel to the third axis Y, thus separating them from the bearing portion 1121 of the bearing structure 112B. Furthermore, the push button 1161 can be reset in a direction opposite to the first direction D1 by the elastic force of the fourth elastic element 1164. Specifically, the push button 1161 has two inclined surfaces 1161a, and each positioning element 1162 correspondingly has an inclined surface 1162b. The push button 1161 can drive the positioning elements 1162 to move as described above by the pushing action of the inclined surfaces 1161a against the inclined surfaces 1162b.

[0115] The following further describes the detailed configuration and operation of the pushing component 128 of the clamping structure 120 in this embodiment.

[0116] Please refer to Figure 9AEach pushing assembly 128 in this embodiment includes two push rods 1281 and a button 1282. The two push rods 1281 are pivotally connected to each other and connected to the button 1282. The clamping portion 1122 of the supporting structure 112 has two guide portions 1122a. The two guide portions 1122a are, for example, components extending from or assembled within the housing of the clamping portion 1122, and correspond to the two pushing assemblies 128 respectively. The two push rods 1281 are respectively attached to the upper and lower opposite sides of the corresponding guide portions 1122a. The user can press the button 1282 to move the pushing assembly 128 along the guide portion 1122a in the third axis Y, so that the two push rods 1281 are relatively unfolded by the guide portion 1122a and push against the clamping member 122 and the corresponding supporting portion 1121 respectively. Thus, the clamping member 122 and the corresponding supporting portion 1121 are moved away from each other in the second axis Z.

[0117] Furthermore, in this embodiment, the clamping structure 120 includes two fifth elastic elements 129, each corresponding to one of the two pushing components 128. Each fifth elastic element 129 is connected to the button 1282 of the corresponding pushing component 128 and the corresponding support structure. Figure 8 , Figure 9A and Figure 9B The diagram shows the space between the retaining walls 1122b of the clamping portion 1122 (illustrated as the supporting structure 112A). The retaining walls 1122b are, for example, components extending from or assembled within the housing of the clamping portion 1122. The pushing assembly 128 can be reset in a direction away from the guide portion 1122a by the elastic force of the fifth elastic member 129.

[0118] The following describes the manner in which the expansion device 100 is electrically connected to the electronic device 50 in this embodiment.

Figure 14A and Figure 14B Draw them separately Figure 13A and Figure 13B Electrical connectors connect electronic devices. Please refer to [reference needed]. Figure 12 In this embodiment, the device body 110 includes an electrical connector 118, which is disposed on the support structure 112A and can be plugged into the electronic device 50 along the first axial direction X. Furthermore, the electrical connector 118 is pivotally connected to the clamping portion 1122 of the support structure 112A along a rotation axis A parallel to the third axial direction Y, and can rotate along the rotation axis A to... Figure 13A or Figure 13BThe tilt is shown. Therefore, even if the electrical connector 118 is subjected to external pressure during the installation of the electronic device 50, the electrical connector 118 can be tilted as shown. Figure 14A or Figure 14B The tilting shown will not cause the electrical connector 118 to bend or the electronic device 50 to be damaged, thereby improving the durability of the expansion device 100 and the electronic device 50.

[0120] Figure 15 yes Figure 12 A three-dimensional view of the shaft hole of the electrical connector and the supporting structure. Figure 16 yes Figure 15 A side view of the shaft hole of the electrical connector and the supporting structure. Please refer to... Figure 15 and Figure 16 In this embodiment, the electrical connector 118 has a shaft portion 1181, and the clamping portion 1122 of the supporting structure 112A has a shaft hole H. The shaft portion 1181 is pivotally connected to the shaft hole H along the rotation axis A. The frictional force between the shaft hole H and the shaft portion 1181 can fix the tilt angle of the electrical connector 118. In addition, the shaft portion 1181 has a protrusion P1, and the inner wall of the shaft hole H has a concave point P2. When the electrical connector 118 is in a horizontal state, the protrusion P1 can be positioned at the concave point P2, so that the user can be sure that the electrical connector 118 is in a horizontal state.

[0121] Figure 17 This is a partial three-dimensional structural view of the main body of the device according to another embodiment of the present invention. Figures 18A to 18C yes Figure 17 The flowchart of the main body of the device. Figures 17 to 18C The expansion device 100' shown is generally similar in configuration and operation to the expansion device 100 of the aforementioned embodiment. The same or similar components will be represented by the same or similar element symbols, and the same configuration and operation will not be described again hereafter.

[0122] Please refer to Figure 17 One of the main differences between expansion device 100' and expansion device 100 is that the two load-bearing structures 112A' and 112B' of expansion device 100' can be supported by the elastic force of the first elastic element 114'. Figure 18B The second state shown (corresponding to) Figure 3 (as shown) relative to the sliding point Figure 18A The first state shown (corresponding to) Figure 1 (as shown in the diagram). That is, the elastic force of the first elastic element 114' of the expansion device 100' is used to drive the two supporting structures 112A' and 112B' to close, rather than the elastic force of the first elastic element 114' of the expansion device 100 being used to drive the two supporting structures 112A and 112B to unfold.

[0123] Based on the aforementioned differences between the expansion device 100' and the expansion device 100, the positioning methods of the positioning component 116' and the positioning component 116 are also slightly different. Specifically, the user can resist the elastic force of the first elastic member 114' and pull the bearing structure 112B' in a direction opposite to the first direction D1, so that the bearing structure 112B' moves from... Figure 18A The first state shown is moved to Figure 18B The second state is shown. In this state, the two positioning members 1162' of the positioning assembly 116' will be moved away from each other in a direction parallel to the third axis (Y) by the elastic force of the third elastic member 1163', in order to resist the elastic force of the first elastic member 114'. Figure 18B The supporting structure 112B' is positioned in the second state, as shown. In the second state, the user can place the electronic device 50 on the supporting structures 112A' and 112B' (as shown). Figure 6 As shown), and then, resisting the elastic force of the fourth elastic element 1164', a force is applied to the push button 1161', causing it to move along the first direction D1 as shown. Figure 18C The two positioning members 1162' are brought closer together in a direction parallel to the third axis Y to release the bearing structure 112B, thereby moving the bearing structure 112B along the first direction D1 until it clamps the electronic device 50 (as shown). Figure 7 (As shown).

[0124] Figure 19 yes Figure 17 A partial perspective view of the expansion device. Figures 20A to 20E yes Figure 19 The flowchart shows the operation of the clamping structure. Another major difference between the expansion device 100' and the expansion device 100 is that the clamping member 122' of the clamping structure 120' of the expansion device 100' can be held by the elastic force of the second elastic member 124'. Figure 20A The second position shown Figure 20B The first position movement is shown. That is, the elastic force of the second elastic member 124' of the expansion device 100' is used to drive the clamping member 122' to unfold, rather than the elastic force of the second elastic member 124' of the expansion device 100 being used to drive the clamping member 122 to retract. Furthermore, the second elastic member 124' of the expansion device 100' is directly compressed between the clamping member 122 and the support portion 1121, thus omitting the configuration of the second elastic member 126 in the aforementioned embodiment.

[0125] Based on the above differences between the expansion device 100' and the expansion device 100, the expansion device 100' does not need to be equipped with the push component 128 as the expansion device 100. Instead, each clamping structure 120' needs to be equipped with a positioning member 121 for positioning the clamping member 122' and a sixth elastic member 123 for applying force to the positioning member 121.

[0126] Specifically, the positioning element 121 is movably disposed on the corresponding bearing structure along the first axial direction X. Figures 19 to 20E Within the clamping portion 1122' of the support structure 112A', a sixth elastic member 123 is connected between the positioning member 121 and the clamping portion 1122' of the support structure 112A'. The sixth elastic member 123, by virtue of its elastic force, allows... Figure 20A As shown, the positioning member 121 is pushed against the clamping member 122' and the supporting portion 1121', so that the positioning member 121 resists the elastic force of the second elastic member 124' and positions the clamping member 122' and the supporting portion 1121' in the second position. The user can apply force to the positioning member 121 against the elastic force of the sixth elastic member 123, so that it is as shown. Figure 20B As shown, the clamping member 122' and the supporting portion 1121' are moved away from each other along the first axial direction X, so that the clamping member 122' and the supporting portion 1121' are moved to the first position by the elastic force of the second elastic member 124'. Then, the user can release the positioning member 121 so that the positioning member 121 is as shown. Figure 20C As shown, the clamping member 122' and the supporting part 1121' are reset and positioned in the first position by the elastic force of the sixth elastic member 123. At this time, the user can... Figure 20D As shown, the electronic device 50 is placed on the support structure 112A', and then as follows: Figure 20E The elastic force resisting the second elastic member 124' presses the clamping member 122' downward along the second axis Z, so that the clamping member 122' and the bearing portion 1121' jointly clamp the electronic device 50. In this clamping state, because the positioning member 121 positions the clamping member 122' and the bearing portion 1121', it can prevent the second elastic member 124' from releasing the clamping member 122' by its elastic force.

[0127] Figure 21 Draw Figure 20E The electronic device was not fitted with a protective case. When the electronic device is 50... Figure 21 The unprotected housing 52 shown is illustrated in Figure 20E By reducing the dimensions along the first axis X and the second axis Z, the clamping part 1122' and the clamping member 122' can smoothly clamp the electronic device 50 through the aforementioned position and state adjustments.

[0128] Please refer to Figure 20E In this embodiment, the positioning member 121 has first rack portions 1211 and 1212, and the clamping member 122' and the bearing portion 1121' respectively have second rack portions 1221 and 1121a'. The first rack portions 1211 and 1212 respectively mesh with the second rack portions 1221 and 1121a' to position the clamping member 122' and the bearing portion 1121'.

[0129] Figure 22 yes Figure 20EEnlarged views of the first and second rack sections are shown below. Please refer to the following: Figure 22 More specifically, each tooth T1' of the first rack portion 1211 has a first stop surface S1' and a first guide slope S2', and each tooth T2' of the second rack portion 1221 has a second stop surface S3' and a second guide slope S4'. The first stop surface S1' and the second stop surface S3' face each other and prevent the clamping member 122' from moving to the first position. The first guide slope S2' and the second guide slope S4' face each other, and when the user applies downward pressure to the clamping member 122', the clamping member 122' can move downward to the appropriate position to clamp the electronic device 50 by the guidance of the first guide slope S2' and the second guide slope S4' and the slight elastic deformation of the structure. The first rack portion 1212 and the second rack portion 1121a' also have the same or similar design and operation, which will not be described in detail here.

[0130] Figure 23 yes Figure 17 A partial three-dimensional view of the expansion device. Figure 24A and Figure 24B Draw Figure 23 The electrical connector is tilted. Another major difference between expansion device 100' and expansion device 100 is that the device body 110' of expansion device 100' includes at least one torsion spring 119 (two shown), which is connected between the shaft portion 1181' of electrical connector 118' and the clamping portion 1122' of the corresponding support structure 112A'. Electrical connector 118' can resist the elastic force of torsion spring 119 as... Figure 24A or Figure 24B The device is tilted as shown and can be reset by the elastic force of the torsion spring 119. In this embodiment, two torsion springs 119 are respectively disposed on opposite sides of the electrical connector 118' so that the elastic force they provide is average and stable. In other embodiments, only a single torsion spring 119 may be used, and the present invention is not limited to this.
