[0048] Embodiments
[0049] The embodiments of the present application provide a game machine protective shell capable of preventing shaking, as shown in Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , comprising: a handle shell 1 for accommodating a game handle 5, and a main shell 2 for accommodating a game main machine 6.
[0050] The handle shell 1 is provided with a first connecting side 11 for connecting the main shell 2, and a holding side 12. The main shell 2 is provided with a second connecting side 21 corresponding to the first connecting side 11.
[0051] The extension 3 is arranged on the first connecting side 11 and / or the second connecting side 21, and the extension 3 arranged on the first connecting side 11 extends to the second connecting side 21 in a direction away from the holding side 12, and the extension 3 arranged on the second connecting side 21 extends to the first connecting side 11 in a direction close to the holding side 12;
[0052] It can be understood that the extension 3 arranged on the first connecting side 11 and the second connecting side 21 extends to each other, which increases the contact area and the connecting point between the handle shell 1 and the main shell 2, and further makes the contact between the game handle 5 and the game console 6 more closely and firmly, which helps to enhance the connection stability between the game handle 5 and the game console 6;
[0053] The extension 3 is used to abut one or any multiple of the handle shell 1, the main shell 2 and the game console 6 when the game handle 5 and / or the game console 6 is subjected to external force, so as to suppress the shaking amplitude between the game handle 5 and the game console 6.
[0054] When the game handle 5 or the game console 6 is subjected to external force, for example, when the player performs game operation, presses the key 51 or rotates the joystick 52, the extension design of the extension 3 helps to uniformly disperse the external force to the connection, and at the same time, to the game handle 5 and the game console 6, which avoids the external force concentrated in a small range, avoids the local force too large, and thus suppresses the shaking amplitude between the game handle 5 and the game console 6.
[0055] Optionally, the extension 3 can be arranged on the handle shell 1, or arranged on the main shell 2, or arranged on both the handle shell 1 and the main shell 2.
[0056] Of course, the specific arrangement position of the extension 3 is not limited herein.
[0057] Further, as shown in Figure 1 The game machine protective shell has a first surface 41 and a second surface 42, and is provided with a plurality of extensions 3.
[0058] The plurality of extensions 3 are distributed along the circumferential direction of the first connecting side 11 and / or the second connecting side 21, and at least one extension 3 is located on the first surface 41, and at least one extension 3 is located on the second surface 42.
[0059] When the extension 3 on the first surface 41 and the extension 3 on the second surface 42 are subjected to external force or vibration, the extension 3 on the first surface 41 and the extension 3 on the second surface 42 can jointly abut against the connection between the game console 6 and the game handle 5 from two directions, thereby canceling or weakening the force of mutual separation, reducing or eliminating the shaking range, and preventing the game handle 5 from shaking in the transverse direction, thereby further improving the stability of the connection between the game handle 5 and the game console 6.
[0060] It can be understood that the design of the extension 3 on the first surface 41 and the second surface 42 makes the support force and protection ability of the protective shell more symmetrical and balanced. The extension 3 not only depends on the first surface 41 or the second surface 42, but also supports each other from two directions, thereby making the connection more stable and reducing the shaking caused by insufficient unilateral support.
[0061] The plurality of extensions 3 are distributed in the circumferential direction, which can uniformly disperse the pressure and impact from the outside world to multiple points, avoid concentrating pressure on a certain position, and thereby reduce the loosening of the connection between the game console 6 and the game handle 5 caused by excessive force on a single point.
[0062] Further, as shown in Figure 1 , Figure 3 and Figure 6 , the first surface 41 of the handle shell 1 is provided with a plurality of through holes 13, and the second surface 42 of the handle shell 1 is further provided with anti-slip lines 14.
[0063] The through holes 13 on the first surface 41 can optimize the accuracy of the operation of the keys 51 and improve the heat dissipation performance of the game handle 5. The design of the through holes 13 enhances the air permeability of the handle shell 1, which can help dissipate heat and reduce performance degradation caused by overheating of the handle.
[0064] The second surface 42 of the handle shell 1 is designed with anti-slip lines 14, which helps to improve the grip feeling and stability of the handle. The anti-slip lines 14 can increase friction and effectively reduce the sliding phenomenon that may occur during long-time game playing, thereby optimizing the grip feeling of the player.
[0065] Specifically, in some embodiments of the present application, the anti-slip lines 14 are arranged close to the gripping side 12.
[0066] The distribution position of the through holes 13 corresponds to the position of the keys 51 or the rocker 52 provided on the game handle 5, and the shape of the through holes 13 matches the keys 51 or the rocker 52.
[0067] Specifically, the keys 51 and the rocker 52 can pass through the through holes 13 and be exposed to the handle shell 1, which can effectively protect the game handle 5 and will not affect the game operation of the player.
[0068] In some embodiments of the present application, the shape of the through hole 13 is slightly larger than the corresponding button 51 or rocker 52; in order to maintain the flexibility of the game operation controlled by the rocker 52 and the button 51.
[0069] Further, as shown in Figure 2 The handle shell 1 and / or the main machine shell 2 are also provided with a positioning groove 30 matched with the extension part 3;
[0070] The positioning groove 30 is used to fit the extension part 3, realizing the positioning connection of the handle shell 1 and the main machine shell 2.
[0071] The fitting of the positioning groove 30 and the extension part 3 enables the accurate butt joint of the handle shell 1 and the main machine shell 2, which can effectively improve the accuracy of the connection position of the handle shell 1 and the main machine shell 2, and further enhance the stability of the connection. The positioning groove 30 matched with the extension part 3 is opened, and the fitting connection of the positioning groove 30 and the extension part 3 also helps to enhance the extension function of the extension part 3 and reduce the shaking caused by external vibration or the force of hand holding, so that the player can maintain a more stable control experience during the game process.
[0072] Further, as shown in Figure 1 And Figure 8 One of the first connection side 11 and the second connection side 21 is provided with a clamping piece 111, and the other is provided with a clamping groove 211; the clamping piece 111 is used to embed the clamping groove 211, realizing the detachable connection of the handle shell 1 and the main machine shell 2.
[0073] The close cooperation of the clamping piece 111 and the clamping groove 211 can ensure the firm connection of the handle shell 1 and the main machine shell 2, avoiding the loosening caused by external vibration, impact or hand holding operation. In cooperation with the extension part 3, the gamepad 5 will not shake during use, providing a more stable use experience.
[0074] Further, as shown in Figure 2 And Figure 6 The main machine shell 2 comprises a main body 22 and a support 23.
[0075] The support 23 is provided with a rotating shaft 231, and the main body 22 is provided with a rotating shaft seat 221 matched with the rotating shaft 231, and the rotating shaft 231 is rotationally connected to the rotating shaft seat 221, realizing the rotational connection of the support 23 and the main body 22.
[0076] Through the design of the rotating shaft 231 and the rotating shaft seat 221, the support 23 can rotate or adjust within a certain range, so that the game console 6 can be adjusted or positioned in different use scenarios, and the support 23 can meet the needs of different users.
[0077] Further, as shown in Figure 7 The handle shell 1 includes an upper shell 15 and a lower shell 16.
[0078] The upper shell 15 is provided with a first hooking part 151, and the lower shell 16 is provided with a second hooking part 161, the first hooking part 151 is used to hook the second hooking part 161, and the connection of the upper shell 15 and the lower shell 16 is realized.
[0079] Through the design of the first hooking part 151 and the second hooking part 161, the detachable connection of the upper shell 15 and the lower shell 16 is realized, which makes the assembly between the upper shell 15 and the lower shell 16 more convenient, and the upper shell 15 and the lower shell 16 can be quickly disassembled; the detachable connection design facilitates assembly and disassembly during production, improves production flexibility and efficiency, and reduces production cost; the connection design of the first hooking part 151 and the second hooking part 161 can also realize stable connection, and the connection part is not easy to loosen or fall off during use, which increases the stability of the overall structure of the handle shell 1.
[0080] Further, the shape of the extension part 3 includes a trapezoidal shape, and the outer contour of the extension part 3 gradually decreases along the extension direction.
[0081] Understandably, the trapezoidal design of the extension part 3, the outer contour of the extension part 3 gradually decreases along the extension direction; that is, the support area of the part directly connected with the extension part 3 is larger, and there are more force points on the first connecting side 11 or the second connecting side 21, which enhances the connection stability of the extension part 3 and the first connecting side 11 or the second connecting side 21, so that the extension part 3 is not easy to break under external force;
[0082] The trapezoidal shape gradually decreases along the extension direction, so that the design of the extension part 3 is more in line with the natural stability of the mechanical principle; in the case of vibration or impact, the gradually decreasing shape helps to avoid rapid swinging or deviation of the extension part 3, thereby improving the stability of the extension part 3 and enhancing the anti-shaking effect.
[0083] Further, as shown in Figure 5 The main shell 2 is also provided with a heat dissipation groove hole 24.
[0084] Specifically, in some embodiments of the present application, the heat dissipation groove hole 24 is distributed along the circumference of the main shell 2.
[0085] The arrangement of the heat dissipation groove hole 24 can promote the flow of air and heat exchange around the game console 6, reduce heat accumulation, thereby preventing the game console 6 from overheating, and helping the stable operation of the game console 6.
[0086] Further, the handle shell 1 has a first end 17 and a second end 18, and the first direction is from the first end 17 to the second end 18.
[0087] The ratio of the sum of the lengths of all extensions 3 located on the first connecting side 11 in the first direction to the length of the first connecting side 11 in the first direction is between 0.3 and 0.8;
[0088] The ratio of the sum of the lengths of all extensions 3 located on the second connecting side 21 in the first direction to the length of the second connecting side 21 in the first direction is between 0.3 and 0.8.
[0089] The length ratio of the extension 3 to the first connecting side 11 or the second connecting side 21 is between 0.3 and 0.8, which is an appropriate ratio. This helps to ensure the length of the extension 3 so as to provide effective support, suppress the shaking or vibration amplitude of the game controller 5 and the game console 6, and at the same time maintain the operational flexibility of the game controller 5.
[0090] The design of Extension 3 is not only for stability but also for maintaining appropriate flexibility. If the proportion is too high, the handle may become too rigid under extreme usage conditions, affecting its adaptability and comfort. An appropriate proportion can avoid this excessive rigidity, ensuring that Extension 3 retains a certain degree of elasticity or adaptability without sacrificing stability, thus providing a better user experience.
[0091] Preferably, the ratio of the sum of the lengths of all extensions 3 located on the first connecting side 11 in the first direction to the length of the first connecting side 11 in the first direction is between 0.35 and 0.6;
[0092] The ratio of the sum of the lengths of all extensions 3 located on the second connecting side 21 in the first direction to the length of the second connecting side 21 in the first direction is between 0.35 and 0.6.
[0093] The embodiments of this application have at least the following beneficial effects:
[0094] This application provides a game console protective case that prevents shaking, which can reduce the possibility of shaking between the game controller 5 and the game console 6 to a certain extent, enhance the stability of the connection between the game controller 5 and the game console 6, and optimize the user's game operation experience.
[0095] Specifically, at least one of the controller shell 1 and the main unit shell 2 is provided with an extension 3. The extension 3 abuts against one or more of the controller shell 1, the main unit shell 2 and the game console 6, which can suppress the shaking amplitude of the game controller 5 and the game console 6, thereby avoiding the impact of the shaking of the game controller 5 on the game operation.
