DETAILED DESCRIPTION

[0040] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] The following describes the preferred embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the specific embodiments of the present invention. Figures 1 to 4 , which is the preferred structure of a metal card wallet of the present invention.

[0042] like Figures 1 to 11 As shown, the present embodiment provides a metal card holder, comprising: a receiving body 100, a movable component 200 and a decompression device 300.

[0043] The storage body 100 has a receiving cavity 101 with an opening;

[0044] The movable assembly 200 includes a sliding cover 201, a sliding rail 202, and a slider 203. The sliding cover 201 is disposed on an outer side surface of the storage body 100, which is the front side plate 102. The sliding rail 202 is disposed on the front side plate 102, and the slider 203 is disposed on the sliding cover 201. The slider 203 matches the sliding rail 202 to enable the sliding cover 201 to move along the sliding rail 202.

[0045] The decompression device 300 includes a sound generator 301 and a magnet 302. The sound generator 301 is arranged on the front side plate 102, and the magnet 302 includes a sliding magnet 3021 and a fixed magnet 3022. The sliding magnet 3021 is arranged on the sliding cover 201, and the fixed magnet 3022 is arranged on the front side plate 102. When the sliding magnet 3021 on the sliding cover 201 slides with the sliding cover 201, it interacts with the fixed magnet 3022 on the front side plate 102, causing the front side plate 102 to vibrate, thereby causing the sound generator 301 on the front side plate 102 to vibrate and emit sound.

[0046] The present invention provides a metal card holder. When the sliding cover 201 is moved, the sliding magnet 3021 of the sliding cover 201 will cooperate with or repel the fixed magnet 3022 of the front side plate 102. Under the action of the magnets, the front side plate 102 vibrates, thereby affecting the sound generator 301 and causing it to emit a sound. The magnetic force between the sliding magnet 3021 and the fixed magnet 3022 also increases the force feedback when the cover is slid. By repeatedly sliding the sliding cover 201, the user can enjoy a dual auditory and tactile experience in this process, and further relieve stress. Therefore, the present invention is a metal card holder that can meet the user's daily needs for carrying and storing cards and also has a decompression function.

[0047] like Figure 4 and Figure 7As shown, optionally, an ejection assembly 103 is provided in the accommodating cavity 101, and the ejection assembly 103 is provided at the bottom of the accommodating cavity 101. A through hole 104 is provided at the bottom of the front side plate 102; the ejection assembly 103 includes a lever 105, a first gear 106, a second gear 107 and an active rod 108; a transmission connection part 109 is provided at one end of the lever 105, and the transmission connection part 109 is a gear structure, and the other end of the lever 105 is a card toggling part 110; the first gear The wheel 106, the second gear 107, and the transmission connection 109 of the shift lever 105 sequentially engage through gears. The active rod 108 is fixed to the bottom of the sliding cover 201. A mounting hole 111 is provided in the center of the first gear 106. The active rod 108 of the sliding cover 201 passes through the through-hole 104 in the front side plate 102 and is fixedly connected to the mounting hole 111 of the first gear 106. When the sliding cover 201 slides around the active rod 108, the active rod 108 drives the first gear 106 to rotate. These three components form a transmission chain, ensuring continuous and stable power transmission and ensuring that the rotation direction of the shift lever 105 is consistent with the rotation direction of the first gear 106. When the user operates the sliding cover 201 to slide along the active rod 108, the active rod 108 moves accordingly, driving the first gear 106 to rotate.

[0048] Due to the meshing relationship between the first gear 106, the second gear 107, and the transmission connection portion 109 of the lever 108, the rotation of the first gear 106 is further transmitted to the second gear 107, and then transmitted to the lever 105 itself through the transmission connection portion 109 of the lever 108. Finally, the card pushing portion 110 of the lever 105 pushes the card to be ejected, thereby achieving the desired card ejection function.

[0049] Combine Figure 4 and Figure 6 As shown, optionally, the slide rail 202 of the movable assembly 200 includes a first slide rail 204 and a second slide rail 205. The curvature of the first slide rail 204 and the second slide rail 205 are both centered on the through hole 104 on the front plate 102. The track of the first slide rail 204 is longer than that of the second slide rail 205. The slider 203 includes a first slider 206 and a second slider 207.

[0050] Among them, the first slider 206 is installed on the first slide rail 204, and the moving distance of the first slider 206 is limited by the track length of the first slide rail 204; the second slider 207 is installed on the second slide rail 205, and the moving distance of the second slider 207 is limited by the track length of the second slide rail 205.

[0051] In this embodiment, two slide rails are provided to provide greater stability when the cover is slid open. Furthermore, the first slider 206 and the second slider 207 function differently. The first slider 206, through cooperating bolts, clamps the cover 201 and slider 202 to the front side panel 102 and constrains the rotation angle of the cover 201 to the minimum track length of the first or second slide rails 204 and 205. The second slider 207 is connected to the first straight end 1121 of the torsion spring 112, allowing the user to manually open and close the cover, or automatically close it, by acting on the torsion spring 112 through the second slider 207.

[0052] Combine Figure 4 and Figure 9 As shown, optionally, a torsion spring 112 is sleeved on the active rod 108 between the sliding cover 201 and the first gear 106, and the torsion spring 112 includes a first straight tail end 1121 and a second straight tail end 1122, the first straight tail end 1121 is connected to the second slider 207, and the second straight tail end 1122 is fixed in the accommodating cavity 101; when the sliding cover 201 slides, the second slider 207 will squeeze the first straight tail end 1121, further squeezing the straight tail spring.

[0053] As the slide cover 201 slides, the torsion spring 112 is compressed or twisted, storing elastic potential energy. When the slide cover 201 stops sliding or the external force disappears, the torsion spring 112 returns to its original shape, releasing the stored energy and pushing the slide cover 201 back to its original position. This provides a restoring force for the slide cover 201 during the sliding process, allowing it to return to its initial position.

[0054] In some embodiments of the present invention, Figure 2 As shown, the fixed magnet 3022 includes a first fixed magnet 3023, a second fixed magnet 3024, a third fixed magnet 3025 and a fourth fixed magnet 3026; the first fixed magnet 3023, the second fixed magnet 3024, the third fixed magnet 3025 and the fourth fixed magnet 3026 are fixed on the front side plate 106 in sequence; the sliding magnet 3021 can overlap with each fixed magnet in sequence as the sliding cover moves.

[0055] Among them, the magnetic poles of the sliding magnet 3021 are opposite to the magnetic poles of the first fixed magnet 3023 and the fourth fixed magnet 3026. When the sliding magnet 3021 approaches the first fixed magnet 3023 or the fourth fixed magnet 3026, the sliding magnet 3021 will be attracted by the first fixed magnet 3023 and the fourth fixed magnet 3026 respectively; the magnetic poles of the sliding magnet 3021 are the same as the magnetic poles of the second fixed magnet 3024 and the third fixed magnet 3025. When the sliding magnet 3021 approaches the second fixed magnet 3024 or the third fixed magnet 3025, the sliding magnet 3021 will be repelled by the second fixed magnet 3024 or the third fixed magnet 3025 respectively.

[0056] When the sliding cover 201 is in its initial state, the sliding magnet 3021 overlaps with the first fixed magnet 3023. When an external force is applied to the sliding cover, the sliding magnet 3021 is driven to break away from the attraction of the first fixed magnet 3023. Since the second fixed magnet 3024 and the sliding magnet 3021 have the same magnetic pole, a greater force feedback is obtained when the cover is slid. In the middle section between the second fixed magnet 3024 and the third fixed magnet 3025, due to the magnetic field of the magnets themselves, the magnetic field of the sliding magnet 3021, the second fixed magnet 3024 and the third fixed magnet 3025 are in a magnetic field equilibrium zone. The sliding magnet 3021 can stay at this point, and a noticeable feeling can be felt during the sliding process. After passing the third fixed magnet 3025, it is attracted to the fourth fixed magnet 3026. Under the magnetic force of the sliding magnet 3021 and the fourth fixed magnet 3026, the sliding cover 201 is retained in this position, which is the maximum displacement position of the sliding cover 201.

[0057] It is understandable that the fixed magnets are not limited to the above four magnets. Three magnets that can attract the sliding magnets can be set, or more than four magnets can be set, such as 5, 6, 7, etc., to increase the force feedback nodes.

[0058] like Figure 7 As shown, optionally, the storage body 100 further includes a bottom shell 113, and the bottom shell 113 is provided with an anti-falling component 114, which is installed at the exit of the accommodating cavity 101;

[0059] The anti-falling component 114 includes a damping plate 115 and a locking hook 116, which are respectively arranged on the left and right sides of the exit of the accommodating chamber 101; the damping plate 115 increases the friction of the card during the up and down sliding process; the locking hook 116 is used to hook the bottom of the card to prevent the card from falling off from the accommodating chamber 101.

[0060] The damping plate 115 applies a lateral force to the card in the receiving chamber 101, slowing down the card's movement by increasing friction and increasing the friction when the card slides. The locking hook 116 is used to hook the bottom of the card. When the card is fully inserted into the receiving chamber 101, the locking hook 116 will hook the bottom edge of the card. This ensures that even if the metal card holder is hit by external forces or turned upside down, the card will not fall out of the receiving chamber 101.

[0061] Combine Figure 8 Optionally, the front side plate 102 and the sliding cover 201 are provided with a fitting device 117, which is respectively installed at the edge of the front side plate 102 and the edge of the sliding cover 201; an anti-friction sheet 121 is also provided between the sliding cover 201 and the front side plate 102.

[0062] The edges of the front panel 102 and the sliding cover 201 are each provided with a fitting device 117. When the sliding cover 201 is closed, the fitting devices 117 interact to secure the sliding cover 201 to the front panel 102. An anti-friction sheet 121 is also provided between the sliding cover 201 and the front panel 102. This anti-friction sheet 121 is made of a soft material to reduce friction during the sliding of the sliding cover 201.

[0063] Alternatively, as Figure 3 As shown, the sound generator 301 is a tuning fork.

[0064] In the above embodiment, the sound generator 301 is a tuning fork; when the magnet causes the front side plate 102 to vibrate, the tuning fork is driven to vibrate together, thereby providing sound feedback to the user when the sliding cover 201 is slid out or reset.

[0065] It is understandable that the sound generator of the present invention is not limited to a tuning fork. Figure 2 and Figure 3 As shown, the storage body 100 adopts a slim design, and grooves 118 are provided on the inner side of the sliding cover 201 and the front side plate 102.

[0066] In the above embodiment, the storage body 100 adopts a slim design, with grooves 118 provided on the front side panel 102. These grooves 118 not only help reduce material usage, thereby reducing the weight of the metal card holder, but also increase structural stability, avoiding the loss of strength caused by reduced material usage. This design allows the metal card holder to remain durable while becoming lighter and easier to carry, meeting the modern demand for lightweight personal belongings.

[0067] Alternatively, as Figure 2As shown, an anti-slip portion 220 is provided on the outer side of the top of the sliding cover 201. When the sliding cover is opened, this design increases the friction of the user, effectively improves the operating feel, and plays an anti-slip role, making the user feel more relaxed and comfortable when sliding the sliding cover, thereby significantly improving the comfort of the product.

[0068] Alternatively, as Figure 10 and Figure 11 As shown, the rear side panel 119 is provided with a pocket clip 120, which is the opposite surface of the front side panel 102 of the storage body. The user can use this pocket clip 120 to firmly clip the metal card holder to the edge of the pocket of clothes or pants to prevent the card holder from accidentally falling or losing during use.

[0069] In summary, this utility model combines magnetism, mechanical transmission, and acoustic principles to create an innovative metal card holder. Its sliding design, card ejection function, and decompression mechanism provide users with a completely new user experience. Compared to traditional card holders, this utility model significantly improves both functionality and enjoyment.

[0070] The working principle of this utility model is:

[0071] When the user slides the slider, the sliding magnets on the slider and the fixed magnets on the front panel move relative to each other. This magnetic force causes the front panel to vibrate. This vibration is transmitted to the sound generator, causing it to emit a sound. Simultaneously, the sliding of the slider drives the gears and lever in the mechanical transmission structure, thereby ejecting the card. The strategic layout of the multiple fixed magnets generates different magnetic forces during the sliding of the slider, providing rich force feedback and enhancing the user's operational experience.

[0072] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
