Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a chassis and recording / broadcasting equipment. Background Technology

[0002] Recording and broadcasting equipment integrates high-definition video encoding, directing, interaction, and recording and broadcasting platform. It can integrate and synchronously record on-site video, audio, and image signals from electronic devices to generate standardized streaming media files for external live broadcasting, storage, post-editing, and on-demand playback.

[0003] Recording equipment includes a cover and a cabinet. The cover usually has a flange at one end that fits into the insertion part of the cabinet for positioning. The other end of the cover is fixedly connected to the cabinet through a connector, thus realizing the connection between the cover and the cabinet.

[0004] However, in the relevant technology, after the plug and the flange are engaged, there is a gap between the plug and the flange, which makes it easy for the plug to detach from the flange, thus making it inconvenient to install the cover into the box. Utility Model Content

[0005] This application provides an embodiment aimed at improving the problems of high cost and low production efficiency of recording and broadcasting equipment.

[0006] To address the aforementioned technical problems, this application provides a chassis, the chassis comprising:

[0007] The housing includes a receiving groove, and one wall of the receiving groove is provided with a plug-in portion; and

[0008] A cover is provided on the opening of the receiving groove. A limiting part is provided on the side of the cover near the insertion part. The limiting part includes a flange and a spring buckle. One end of the flange is connected to the cover. The spring buckle cooperates with the cover to clamp the insertion part. The spring buckle has a first connecting segment and a second connecting segment that are connected to each other. The end of the first connecting segment that is away from the second connecting segment is connected to the flange. The first connecting segment and the second connecting segment are set at an angle.

[0009] In some embodiments, the cover and the flange together form a connection hole, and the plug is inserted into the connection hole.

[0010] This design allows the cover to be positioned by inserting the connector into the connection hole, thus facilitating the assembly of the chassis.

[0011] In some embodiments, one end of the first connecting segment is connected to the wall of the connecting hole, and the other end of the first connecting segment extends obliquely from the direction close to the plug-in portion toward the direction of insertion of the plug-in portion into the connecting hole, and is connected to the second connecting segment.

[0012] With this configuration, when the plug is inserted into the connection hole, the first connecting segment will abut against it. The inwardly tilted first connecting segment can guide the plug into the connection hole and prevent the second connecting segment from interfering with the plug, thus preventing the plug from being inserted into the connection hole.

[0013] In some embodiments, the limiting portion includes a plurality of spring clips, which are spaced apart within the connecting hole.

[0014] This design, by incorporating multiple spring clips to increase the elastic force on the connector, allows the connector to be positioned more stably within the connection hole.

[0015] In some embodiments, the end of the plug portion away from the groove wall of the receiving groove is provided with a guide arc surface, which cooperates with the hole wall of the connecting hole to guide the plug portion into the connecting hole.

[0016] With this design, when the plug is inserted into the connection hole, the guide arc surface can abut against the hole wall, thereby guiding the plug to be accurately inserted into the connection hole, which in turn facilitates the installation of the cover onto the box.

[0017] In some embodiments, multiple limiting portions are spaced apart, and multiple insertion portions are provided, each corresponding to one of the limiting portions.

[0018] With this design, during the installation of the cover onto the box, multiple limiting parts and multiple plug-in parts work together to position the cover. At the same time, it can also improve the stability of the connection between the end of the cover with the limiting part and the end of the box with the plug-in part.

[0019] In some embodiments, the end of the cover near the insertion portion is folded inward to form a first flange, and one end of the first flange is provided with the flange;

[0020] A support portion is provided on one wall of the receiving groove. The support portion extends circumferentially along the receiving groove. The insertion portion is provided on the inner side of the support portion. The support portion abuts against the first flange.

[0021] This design, by providing a first flange on the outer side of the flange, increases the thickness of the side of the cover with the flange, thereby improving the rigidity of the cover at the flange and enhancing its resistance to deformation. This reduces the impact of the insertion part on the flanged side of the cover when it is inserted into or removed from the flange, thus extending the service life of the cover. Simultaneously, by providing a support part that abuts against the first flange, the length of the insertion part is reduced, thereby increasing the rigidity of the insertion part. Furthermore, the support part can support the first flange, thus improving the stability of the cover at the opening of the receiving groove.

[0022] In some embodiments, the two ends of the cover adjacent to the first flange are folded inward to form a second flange.

[0023] With this configuration, the cover has a first flange and a second flange on all sides. The thickness of the cover on the outer circumferential side is increased by the first flange and the second flange, thereby increasing the rigidity of the cover on the outer circumferential side. This can improve the cover's resistance to deformation, which reduces the impact of external pressure on the cover and extends its service life.

[0024] In some embodiments, the two groove walls adjacent to the receiving groove and the insertion part are provided with guide portions, and the guide portions are recessed with multiple sliding grooves on the surface facing the cover, and the multiple sliding grooves are arranged at intervals along the circumference of the receiving groove;

[0025] Multiple buckles are provided at both ends of the cover near the guide portion. The multiple buckles are arranged at intervals along the circumference of the cover and correspond one-to-one with the multiple sliding grooves.

[0026] The buckle can slide within the groove and engage with the groove to fix the cover onto the box.

[0027] This design, through the interlocking of the snap-fit ​​and the sliding groove, guides the cover, allowing the connector to be accurately inserted into the connection hole without requiring alignment between the connector and the connection hole, thus facilitating the overall assembly of the chassis. It also reduces the rigid contact between the connector and the flange, extending the chassis's lifespan. Furthermore, the snap-fit ​​and sliding interlocking mechanism allows for upper limit positioning of the cover on both sides with snap-fits in the direction away from the groove opening, ensuring the cover remains more stably positioned within the groove.

[0028] In some embodiments, the groove wall opposite to the insertion part is provided with a first locking hole, and the cover is provided with a second locking hole on the side near the first locking hole. The first locking hole and the second locking hole are detachably connected by a connector.

[0029] With this configuration, one end of the cover is clamped and fixed by a snap fastener through a plug-in part, while the other end of the cover is fixed by a connector that engages with the first locking hole and the second locking hole. This allows the cover to be stably placed in the receiving slot and facilitates the assembly and disassembly of the chassis.

[0030] This application also provides a recording and broadcasting device, the recording and broadcasting device comprising:

[0031] Motherboard;

[0032] The recording module is electrically connected to the motherboard; and

[0033] The aforementioned chassis, motherboard, and recording module are all installed within the aforementioned accommodating slot.

[0034] The technical solution of this application allows for the direct formation of a connecting hole on the flange of the limiting portion of the cover. The insertion part extends into the connecting hole and elastically abuts against the spring-loaded buckle, thus limiting one end of the cover. The connecting hole is formed simply by folding the cover, eliminating the need for welding stainless steel plates or beryllium copper sheets. This reduces the cost of the recording equipment and improves its production efficiency. Simultaneously, the spring-loaded buckle elastically abuts against the insertion part, ensuring it remains stably positioned within the connecting hole. This prevents misalignment of the insertion part and the connecting hole during chassis assembly, avoiding inaccurate connection between the connector and the first and second locking holes, thereby facilitating the overall assembly of the recording equipment.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] Recording and broadcasting equipment integrates high-definition video encoding, directing, interaction, and recording and broadcasting platform. It can integrate and synchronously record on-site video, audio, and image signals from electronic devices to generate standardized streaming media files for external live broadcasting, storage, post-editing, and on-demand playback.

[0045] Recording equipment includes a cover and a cabinet. The cover usually has a connection hole at one end that is inserted into the cabinet for positioning. The other end of the cover is fixedly connected to the cabinet through a connector, thus realizing the connection between the cover and the cabinet.

[0046] However, in related technologies, in order to facilitate the insertion of the plug into the connection hole, there is a gap between the plug and the wall of the connection hole after the plug is inserted into the connection hole. This makes it easy for the plug to detach from the connection hole, which makes it inconvenient to install the cover into the box.

[0047] Traditional chassis have stainless steel sheets welded to the surface of the cover near the chassis. By inserting the chassis's connector into the space between the stainless steel sheet and the cover, the stainless steel sheet and the cover clamp the connector, thus ensuring a stable connection between the connector and the cover. However, welding stainless steel or beryllium copper sheets increases the cost of the cover and reduces its production efficiency, which in turn increases the cost of the recording equipment and reduces its production efficiency.

[0048] Please refer to the following: Figures 1 to 3 This application provides a chassis 1000 and a recording and broadcasting device. The recording and broadcasting device includes a motherboard, a recording and broadcasting module, and a chassis 1000. The recording and broadcasting module is electrically connected to the motherboard. Both the motherboard and the recording and broadcasting module are installed inside the chassis 1000. The chassis 1000 can protect the recording and broadcasting module and the motherboard.

[0049] Please see Figure 2The housing 200 is provided with a receiving groove 210. The plug-in part 220 can be formed by folding the housing 200, or it can be detachably installed on the housing 200; no specific limitation is made here. Preferably, the plug-in part 220 is formed by folding the housing 200, which reduces the installation steps of the housing 200 and thus improves the production efficiency of the housing 200. The housing 200 can be made of various materials, including galvanized sheet, cold-rolled sheet, and other materials; no specific limitation is made here.

[0050] Please see Figure 2 The cover 100 is placed over the opening of the receiving groove 210. A limiting part 110 is provided on the side of the cover 100 near the insertion part 220. The cover 100 and the limiting part 110 can be integrally formed, or they can be detachably connected; no specific limitation is made here. Preferably, the cover 100 and the limiting part 110 are integrally formed, which reduces the installation steps of the cover 100 and thus improves the production efficiency of the box 200.

[0051] Please see Figure 3 The limiting part 110 includes a flange 111 and a spring clip 112. One end of the flange 111 is connected to the cover 100. The spring clip 112 cooperates with the cover 100 to clamp the insertion part 220. There are many ways in which the spring clip 112 is connected to the flange 111. The spring clip 112 can be detachably connected to the flange 111, such as by insertion or screw connection. Alternatively, the spring clip 112 can be integrally formed with the flange 111. No specific limitation is made here. Preferably, the spring clip 112 is integrally formed with the flange 111, which can reduce the installation steps of the cover 100 and thus improve the production efficiency of the cover 100.

[0052] The spring clip 112 has a first connecting segment 1121 and a second connecting segment 1122 that are connected to each other. The end of the first connecting segment 1121 facing away from the second connecting segment 1122 is connected to the flange 111. The first connecting segment 1121 and the second connecting segment 1122 are set at an angle. It should be noted that this angle can be one of an acute angle, an obtuse angle, or a right angle. The spring clip 112 can be used to clamp the plug-in part 220 with the cover 100, or it can be used as the connection point of the first connecting segment 1121 and the second connecting segment 1122 to clamp the plug-in part 220 with the cover 100. No specific limitation is made here.

[0053] There are many ways in which the insertion part 220 extends between the snap 112 and the cover 100. For example, the flange 111 is stepped, with a vertically extending first section and a horizontally extending second section. The first connecting section 1121 is connected to the surface of the second section facing the insertion part 220, and the insertion part 220 extends between the snap 112 and the cover 100 from the position between the second section and the cover 100. Another example is that the flange 111 and the cover 100 together form a notch, the first connecting section 1121 is connected to the notch, and the insertion part 220 extends between the snap 112 and the cover from the notch. These are just a few examples.

[0054] Compared to the traditional chassis 1000, which has a stainless steel sheet welded to the surface of the cover 100 near the chassis 200, and uses the stainless steel sheet to clamp the plug-in part 220 in cooperation with the cover 100, the cost of setting the spring buckle 112 is lower than that of the stainless steel sheet. Moreover, the installation of the spring buckle 112 is more efficient than welding the stainless steel sheet. Therefore, setting the spring buckle 112 reduces the production cost of the chassis 200 and improves the production efficiency of the chassis 200.

[0055] Both the motherboard and the recording module are installed in the receiving slot 210. For ease of installation, the motherboard and the recording module are usually installed at the bottom of the receiving slot 210. The recording device includes multiple mounting rivets 260, which are fixedly installed in the slot section of the receiving slot 210. The motherboard and the recording module are installed at the bottom of the receiving slot 210 by connecting with the mounting rivets 260. The mounting rivets 260 can be used to position the motherboard and the recording module, thereby installing the motherboard and the recording module in the designated position of the receiving slot 210, which facilitates the overall assembly of the recording device.

[0056] Please see Figure 2 Since the recording and broadcasting equipment generates heat when it is working, the recording and broadcasting module and the motherboard will generate heat. If the heat accumulates in the accommodating slot 210, the temperature inside the accommodating slot 210 will rise, which will affect the recording and broadcasting module and the motherboard. Therefore, multiple heat dissipation holes 270 are provided through the slot wall of the accommodating slot 210. The heat generated by the recording and broadcasting module and the motherboard is dissipated to the external environment through the heat dissipation holes 270, thereby cooling the chassis 1000.

[0057] Please see Figure 2 Recording and broadcasting equipment usually needs to be connected to external operating devices. Therefore, the wall of the receiving slot 210 is provided with multiple plug-in interfaces 280 so that the external operating devices can be connected to the motherboard through the plug-in interfaces 280.

[0058] In the technical solution of this application, the plug-in part 220 is clamped by the spring buckle 112 cooperating with the cover 100. At the same time, the first connecting section 1121 and the second connecting section 1122, which are set at an angle, can improve the elasticity of the spring buckle 112. This can prevent the chassis 1000 from shaking during the assembly process, causing the plug-in part 220 to fall off between the cover 100 and the spring buckle 112, thereby facilitating the overall assembly of the recording and broadcasting equipment.

[0059] Specifically, please refer to Figure 3 The cover and the flange cover form a connection hole 113, and the plug part 220 is inserted into the connection hole 113. With this configuration, the cover 100 can be positioned by inserting the plug part 220 into the connection hole 113, thereby facilitating the assembly of the chassis 1000.

[0060] It should be noted that the first connecting segment 1121 and the second connecting segment 1122 have various extension methods in the direction in which the insertion part 220 is inserted into the connecting hole 113. For example, the end of the first connecting segment 1121 away from the flange 111 extends towards the inside of the housing 200, and the end of the second connecting segment 1122 away from the first connecting part extends towards the inside of the housing 200. Alternatively, the end of the first connecting segment 1121 away from the flange 111 extends towards the outside of the housing 200, and the end of the second connecting segment 1122 away from the first connecting part extends towards the outside of the housing 200. No specific limitations are made here.

[0061] Preferably, please refer to Figure 4 One end of the first connecting segment 1121 is connected to the wall of the connecting hole 113, and the other end of the first connecting segment 1121 extends obliquely from the direction near the plug-in part 220 toward the direction of the plug-in part 220 inserting into the connecting hole 113, and is connected to the second connecting segment 1122. It can be understood that the end of the first connecting segment 1121 away from the flange 111 extends toward the inside of the housing 200, and the end of the second connecting segment 1122 away from the first connecting segment 1121 extends toward the inside of the housing 200, so that the first connecting segment 1121 is obliquely set. When the plug-in part 220 is inserted into the connecting hole 113, it will abut against the first connecting segment 1121. The inwardly oblique first connecting segment 1121 can guide the plug-in part 220 to insert into the connecting hole 113, and avoid the second connecting segment 1122 interfering with the plug-in part 220, which would prevent the plug-in part 220 from being inserted into the connecting hole 113.

[0062] Please see Figure 4 In some embodiments of this application, the limiting part 110 includes a plurality of spring clips 112, which are spaced apart within the connecting hole 113. This arrangement increases the elastic force on the insertion part 220 by providing a plurality of spring clips 112, thereby allowing the insertion part 220 to be more stably located within the connecting hole 113.

[0063] Please see Figure 2 In some embodiments of this application, multiple limiting portions 110 are spaced apart, and multiple insertion portions 220 are provided, each corresponding to one of the limiting portions 110. This arrangement allows the cover 100 to be positioned by the cooperation of the multiple limiting portions 110 and the multiple insertion portions 220 during installation on the housing 200. Simultaneously, it improves the stability of the connection between the end of the cover 100 with the limiting portion 110 and the end of the housing 200 with the insertion portion 220.

[0064] Please see Figure 5 In some embodiments of this application, the end of the insertion part 220 away from the groove wall of the receiving groove 210 is provided with a guide arc surface 221. The guide arc surface 221 cooperates with the hole wall of the connecting hole 113 to guide the insertion part 220 into the connecting hole 113. With this configuration, when the insertion part 220 is inserted into the connecting hole 113, the guide arc surface 221 can abut against the hole wall of the connecting hole 113, thereby guiding the insertion part 220 to be accurately inserted into the connecting hole 113, which facilitates the installation of the cover 100 onto the housing 200.

[0065] It should be noted that the insertion part 220 has an insertion direction, a width direction, and a thickness direction. The insertion part 220 is inserted into the connection hole 113 along the insertion direction. The guide arc surface 221 can be formed from one end of the insertion part 220 in the thickness direction, or it can be formed from one end of the insertion part 220 in the width direction; no specific limitation is made here. Preferably, guide arc surfaces 221 are formed at both ends of the insertion part 220 in the width direction, and the length of the insertion part 220 in the width direction is greater than the length of the insertion part 220 in the thickness direction. Therefore, the curvature of the guide arc surface 221 formed by the insertion part 220 in the width direction can be set to be relatively large, thereby enabling the guide arc surface 221 to play a better guiding role. Meanwhile, both ends of the plug portion 220 in the width direction are formed with guide arc surfaces 221, so that both ends of the plug portion 220 in the width direction can play a guiding role when they come into contact with the hole wall of the connection hole 113, thereby making it easier for the user to insert the plug portion 220 into the connection hole 113.

[0066] Please see Figure 4In some embodiments of this application, the end of the cover 100 near the insertion portion 220 is folded inward to form a first flange 130, and one end of the first flange 130 is provided with a flange 111; a support portion 240 is protruding from one wall of the receiving groove 210, the support portion 240 extends circumferentially along the receiving groove 210, and the insertion portion 220 is protruding from the inner side of the support portion 240, the support portion 240 abuts against the first flange 130. This configuration, by providing the first flange 130 on the outer side of the flange 111, increases the thickness of the side of the cover 100 where the flange 111 is provided, thereby increasing the rigidity of the cover 100 at the flange 111 and improving the deformation resistance of the side of the cover 100 where the flange 111 is provided. This reduces the impact of the insertion portion 220 on the side of the cover 100 where the flange 111 is provided when inserting or removing the flange 111, thus extending the service life of the cover 100. Meanwhile, by setting the support part 240 to abut against the first flange 130 to reduce the length of the insertion part 220, the rigidity of the insertion part 220 is improved, and the support part 240 can support the first flange 130, thereby improving the stability of the cover 100 in the groove of the receiving groove 210.

[0067] Further, please refer to Figure 4 The two ends of the cover 100 adjacent to the first flange 130 are both folded inward to form a second flange 140. With this configuration, the cover 100 has a first flange 130 and a second flange 140 on all its circumferences. The first flange 130 and the second flange 140 increase the thickness of the cover 100 on the outer circumference, thereby increasing the rigidity of the cover 100 on the outer circumference. This can improve the cover 100's resistance to deformation, which reduces the impact of external pressure on the cover 100 and extends the service life of the cover 100.

[0068] Considering that there are only two ways to insert the plug part 220 into the connection hole 113 during the installation of the cover 100 and the box 200, one is to first place the cover 100 in the groove of the receiving groove 210, and then slide the cover 100 so that the plug part 220 is inserted into the connection hole 113. However, during the sliding of the cover 100, the connection between the plug part 220 and the connection hole 113 will be covered by the cover 100 and the box 200, which makes it inconvenient for the plug part 220 and the connection hole 113 to be aligned. Another method is to first place one end of the cover 100 with the limiting part 110 abutting against the box 200. In this case, the cover 100 is placed at an angle in the groove of the receiving groove 210, and the insertion part 220 is inserted into the connecting hole 113. Then, the cover 100 is rotated with the end of the cover 100 with the limiting part 110 as the rotation axis so that the cover 100 covers the groove of the receiving groove 210. However, during the rotation of the cover 100, the limiting part 110 and the flange 111 will have a large rigid contact, which can easily cause damage to the flange 111 and the insertion part 220.

[0069] In view of this, please refer to Figure 2 The two walls of the receiving groove 210 and the insertion part 220 are each provided with a guide part 250. The guide part 250 is recessed on the surface of the cover 100 and has multiple sliding grooves 251. The multiple sliding grooves 251 are arranged at intervals along the circumference of the receiving groove 210. The two ends of the cover 100 near the guide part 250 are provided with multiple buckles 150. The multiple buckles 150 are arranged at intervals along the circumference of the cover 100 and are provided in correspondence with the multiple sliding grooves 251. The buckles 150 can slide in the sliding grooves 251 and engage with the sliding grooves 251 to fix the cover 100 on the box 200.

[0070] This design, through the engagement of the snap fastener 150 and the sliding groove 251, guides the cover 100, allowing the plug 220 to be accurately inserted into the connecting hole 113 without requiring alignment between the plug 220 and the connecting hole 113, thus facilitating the overall assembly of the chassis 1000. It also reduces the rigid contact between the plug 220 and the flange 111, thereby extending the service life of the chassis 200. Simultaneously, the engagement of the snap fastener 150 and the sliding snap fastener 150 provides upper limits on both sides of the cover 100 in the direction away from the opening of the receiving groove 210, ensuring the cover 100 is more stably positioned within the opening of the receiving groove 210.

[0071] During the installation of the cover 100 onto the box 200, the buckle 150 is first inserted into the slide groove 251, and then the cover 100 is slid to engage the buckle 150 with the slide groove 251. At this time, the plug part 220 is inserted into the connection hole 113, and finally the first locking hole 230 and the second locking hole 120 are connected by the connector.

[0072] When disassembling the cover 100, first remove the connector from the first locking hole 230 and the second locking hole 120. Then slide the cover 100 to disengage the buckle 150 from the sliding insert. At this time, the insert part 220 exits the connecting hole 113. Finally, operate the cover 100 to drive the buckle 150 out of the sliding insert so that the cover 100 can be removed from the slot of the receiving groove 210.

[0073] Please see Figure 2In some embodiments of this application, a first locking hole 230 is provided on the groove wall opposite to the insertion part 220 of the receiving groove 210, and a second locking hole 120 is provided on the side of the cover 100 near the first locking hole 230. The first locking hole 230 and the second locking hole 120 are detachably connected by a connector. It can be understood that the insertion part 220 and the first locking hole 230 are respectively provided on two opposite groove walls of the receiving groove 210, and the limiting part 110 and the second locking hole 120 are respectively provided on two opposite sides of the cover 100.
