Description

Technical Field

[0001] This utility model relates to the field of computer chassis technology, specifically a highly customizable chassis projection device based on magnetic assembly. Background Technology

[0002] A computer case is an outer shell that houses and protects all the major internal components of a computer. When using a computer case, a projection device can be added to increase its overall usability. However, traditional projection devices have a fixed position, making them inconvenient to adjust flexibly. In addition, projection devices cannot provide protection for the connecting cables.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese patent CN203616703U, published on 2014-05-28) provides a computer chassis with a projection module, comprising a chassis body and a side panel. The chassis body houses a projection module mounting structure, and the chassis body corresponding to the projection module mounting structure has a projection window. An optical projection module is mounted on the projection module mounting structure. The projection module mounting structure is located at the top front of the chassis body, and the chassis body has ventilation holes for heat dissipation of the optical projection module. The optical projection module includes a projection lens, a projection module shell, a projection module core, and external connecting cables. The chassis body also has a motherboard mounting structure and a hard drive mounting structure. By integrating economy, convenience, and playability, it satisfies users' need for low-cost access to similar high-cost, high-specification products on the market, and its simple structure facilitates portability.

[0004] The aforementioned mechanism connects the projection module to the chassis using an external connection cable. However, the external connection cable itself lacks sufficient protection during use, causing the connection point to be exposed to the outside environment, which can easily lead to breakage. Utility Model Content

[0005] The purpose of this utility model is to provide a highly customizable chassis projection device based on magnetic assembly, so as to solve the problems mentioned in the background art that the traditional projection device has a fixed position when in use, which is not convenient for flexible adjustment, and the projection device cannot limit and protect the connecting wires when in use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly customizable chassis projection device based on magnetic assembly, comprising a fixed base, a magnetic block engaged at the top of the fixed base, and a positioning component engaged at the top of the magnetic block, the positioning component passing through the magnetic block and extending into the interior of the fixed base, and a mounting seat installed at the bottom of the fixed base; a cable inlet is provided on the side of the fixed base, and a cable limiting mechanism for fixing the cable is provided on the outer side of the cable inlet, the cable limiting mechanism including a mounting box, the mounting box being disposed on the side of the fixed base, a movable block being slidably connected inside the mounting box, and a baffle plate being fixedly connected to the bottom of the movable block, and a lever being fixedly connected to the outer side of the baffle plate; a sealing mechanism for filling gaps to prevent lens shaking is provided inside the mounting seat.

[0007] Furthermore, a connecting spring is installed at the bottom of the movable block, and the movable block and the mounting box form an elastic structure through the connecting spring.

[0008] Furthermore, the front and rear ends of the mounting box are provided with sliding grooves, and the front and rear ends of the movable block are fixedly connected with sliders that match the sliding grooves. The mounting box and the movable block are connected by sliding sliders and sliding grooves to form a sliding mechanism.

[0009] Furthermore, the positions of the cable inlet and the shield correspond to each other, and the width of the shield is greater than the width of the cable inlet.

[0010] Furthermore, the sealing mechanism includes a first elastic airbag, which is fitted inside the mounting base. A connecting tube is installed at the bottom end of the first elastic airbag, and a second elastic airbag is fixedly connected to the bottom end of the connecting tube.

[0011] Furthermore, the second elastic airbag is disposed at the lower end of the inner side of the mounting base, and the inner diameter of the second elastic airbag is larger than the inner diameter of the first elastic airbag.

[0012] Furthermore, the connecting tubes are distributed at equal angles at the top of the second elastic airbag, and the second elastic airbag and the first elastic airbag are connected by the connecting tubes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The magnetic block is connected to the fixed base using a positioning component. The magnetic block itself is magnetic and can be installed in any position inside the chassis, allowing the height of the fixed base and the magnetic block to be flexibly adjusted, thereby better realizing the use of the projection equipment and increasing the flexibility of use.

[0015] Furthermore, by moving the lever towards the inside of the mounting box, the lever moves the shielding plate synchronously, allowing the wire to pass through the mounting box and connect to the chassis. Then, the tension applied to the lever is released, allowing the lever to automatically reset due to the elasticity of the connecting spring. This causes the shielding plate to press and limit the upper end of the wire, effectively preventing the wire from becoming loose when the projection equipment is adjusted or used.

[0016] Furthermore, by using a shield to cover the cable inlet, excessive dust can be prevented from entering the base, thus effectively extending the overall service life of the base.

[0017] 2. When connecting the lens to the mounting base, the lens is snapped into place. By applying a certain amount of pressure to the first elastic airbag, the first elastic airbag can introduce its internal gas into the second elastic airbag through the connecting tube. The second elastic airbag can fill and seal the edge where the projection lens connects to the mounting base, reducing the shaking caused by gaps, and thus making the projection lens more stable during use.

[0018] Furthermore, when the lever is used to move the movable block up and down, the slider and groove enable the movable block to move more smoothly, preventing the movable block from getting stuck during movement. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 6 The technical solution presented addresses the problems of traditional projection devices having a fixed position during use, hindering flexible adjustment, and lacking protection for connecting cables. This magnetically assembled, height-customizable chassis projection device discloses a cable limiting mechanism, including a fixed base 1. A magnetic block 2 is engaged at the top of the fixed base 1, and a positioning element 3 is engaged at the top of the magnetic block 2. The positioning element 3 passes through the magnetic block 2 and extends into the interior of the fixed base 1. A mounting base 4 is installed at the bottom of the fixed base 1. A cable inlet 5 is provided on the side of the fixed base 1, and a cable limiting mechanism for fixing the cable is provided on the outer side of the cable inlet 5. The cable limiting mechanism includes a mounting base 4. The mounting box 6 is located on the side of the fixed base 1. A movable block 8 is slidably connected inside the mounting box 6, and a baffle plate 9 is fixedly connected to the bottom end of the movable block 8. A lever 10 is fixedly connected to the outside of the baffle plate 9. A connecting spring 7 is installed at the bottom end of the movable block 8, and the movable block 8 and the mounting box 6 form an elastic structure through the connecting spring 7. Slide grooves 12 are opened at both the front and rear ends inside the mounting box 6, and sliders 11 that match the slide grooves 12 are fixedly connected to both the front and rear ends of the movable block 8. The mounting box 6 and the movable block 8 form a sliding mechanism through the sliding connection of the sliders 11 and the slide grooves 12. The positions of the cable inlet 5 and the baffle plate 9 correspond to each other, and the width of the baffle plate 9 is greater than the width of the cable inlet 5.

[0028] In this example, the magnetic block 2 is connected to the fixed base 1 using the positioning component 3. The magnetic block 2 is magnetic and can be installed at any position inside the chassis, allowing the height of the fixed base 1 and the magnetic block 2 to be flexibly adjusted, thus better enabling the use of the projection equipment and increasing its flexibility. When using the projection equipment, the cable needs to be connected from the cable inlet 5. However, during the connection, the cable may shift due to the flexible position of the projection equipment, leading to loosening. By moving the lever 10 towards the inside of the mounting box 6, the lever 10 moves the baffle 9 synchronously, allowing the cable to pass through the mounting box 6 and connect to the chassis. Then, the lever 10 is removed. The applied tension causes the lever 10 to automatically reset via the spring force of the connecting spring 7, thereby pressing the shield 9 against the upper end of the wire. The shield 9 effectively limits and fixes the position of the wire, preventing the wire from becoming loose during position adjustment and use of the projection device, thus increasing the overall usability. When the projection device is not in use, the shield 9 can cover the cable inlet 5, reducing the amount of dust entering the fixed base 1 and effectively extending its service life. When the lever 10 moves the movable block 8 up and down, the slider 11 and the slide groove 12 ensure smoother movement of the movable block 8, preventing it from getting stuck.

[0029] Example 2: Figure 1 , Figure 4 and Figure 5 The technical solution shown addresses the issue of lens loosening during connection between the projection lens and the mounting base 4. This highly customizable chassis projection device based on magnetic assembly discloses a sealing mechanism. The mounting base 4 has an internal sealing mechanism to fill gaps and prevent lens movement. The sealing mechanism includes a first elastic airbag 13, which fits snugly inside the mounting base 4. A connecting tube 14 is installed at the bottom of the first elastic airbag 13, and a second elastic airbag 15 is fixedly connected to the bottom of the connecting tube 14. The second elastic airbag 15 is located at the lower inner side of the mounting base 4, and its inner diameter is larger than that of the first elastic airbag 13. The connecting tubes 14 are evenly distributed at the top of the second elastic airbag 15, and the second elastic airbag 15 and the first elastic airbag 13 are connected via the connecting tubes 14.

[0030] In this example, when connecting the lens to the mounting base 4, the lens is snapped into place. By applying a certain compressive force to the first elastic airbag 13 using the projection lens, the first elastic airbag 13 can introduce internal gas into the second elastic airbag 15 through the connecting pipe 14. The second elastic airbag 15 can fill and seal the connection edge between the projection lens and the mounting base 4, reducing the shaking caused by gaps, and thus making the projection lens more stable during use.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
