Description

Technical Field

[0001] This utility model belongs to the field of LCD TV stand technology, specifically an embedded stand for LCD TVs. Background Technology

[0002] Currently, in existing technologies, the base of LCD TVs is generally fixed to the bottom of the TV using bolts. This structure uses threaded holes pre-set on the back cover or bracket of the TV to fasten the bolts, thereby achieving a mechanical connection between the base and the screen.

[0003] Although this installation method is simple in structure and reliable in connection, in actual application, especially in the product transportation process, it is usually necessary to separate the base from the TV body. This design helps to reduce the overall thickness and volume of the packaging, reduce the potential risks to the screen caused by vibration and impact during transportation, and also helps to optimize storage space, reduce logistics costs, and improve the efficiency of terminal packaging and disassembly.

[0004] Although bolted connections have advantages in terms of structural strength and reliability, they have significant shortcomings in terms of user installation experience, mainly in terms of cumbersome installation process and poor user experience. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an embedded base for LCD TVs, which solves the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an embedded base for an LCD TV, comprising an LCD TV housing, a storage groove at the bottom of the LCD TV housing, a cavity at the top of the storage groove, a base body movably installed in the storage groove, a rotating shaft fixedly connected to the top of the base body, and the end of the rotating shaft extending into the cavity.

[0007] The inner wall of the cavity is provided with a first limiting groove, a limiting block is provided on one side of the first limiting groove, an elastic rod is connected to the outer wall of the rotating shaft, a limiting protrusion is fixedly installed on the elastic rod, a spring buckle is connected to the adjacent side of the limiting protrusion, and the bottom of the elastic rod extends to the bottom of the base body.

[0008] The outer wall of the rotating shaft has a first guide groove in a longitudinal structure, and the outer side of the rotating shaft has a second guide groove in a transverse structure. The first guide groove and the second guide groove are connected. The inner wall of the storage groove has a second limiting groove for use with the snap fastener.

[0009] As a further embodiment of this utility model: the base body is a semi-circular structure, the storage groove fits into the base body, and the storage groove is also a semi-circular structure.

[0010] As a further embodiment of this utility model: the limiting protrusion has a conical structure, the limiting protrusion is smaller than the spring buckle, and the spring buckle is larger than the first limiting groove.

[0011] As a further embodiment of this utility model: the cross-sections of the first guide groove and the second guide groove are L-shaped.

[0012] As a further embodiment of this utility model: the cross-sections of the first guide groove and the second guide groove are L-shaped.

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

[0014] 1. This utility model embeds the base bracket into the storage groove at the bottom of the TV casing and uses a rotating shaft to achieve positioning with the cavity. The spring buckle on the elastic rod on one side of the rotating shaft continuously presses the inner wall of the cavity during storage, forming a stable fixation, so that the base can be hidden inside the TV. This design is not only simple and compact in structure, effectively maintaining the integrity and aesthetics of the whole appearance, but also significantly reduces the overall thickness and volume during the packaging and transportation stage, which helps to reduce packaging materials, save warehousing and logistics costs, and enhance transportation safety.

[0015] 2. During use, users simply need to manually pull the base out of the storage slot and rotate it 90° to quickly unfold the base. At this point, the spring clips on the elastic rod accurately fall into the second limit slot, achieving automatic positioning and locking of the rotation angle. The upper sides of the base then contact the bottom of the TV to form a stable support structure. The entire operation process requires no tools or bolts for tightening, greatly simplifying the installation process, lowering the barrier to entry, and improving the product's ease of use and reliability.

[0024] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0025] like Figures 1-7 As shown, this utility model provides a technical solution:

[0026] An embedded stand for an LCD TV includes an LCD TV housing 1, a storage groove 2 at the bottom of the LCD TV housing 1, a cavity 3 connected to the top of the storage groove 2, a base body 4 movably installed in the storage groove 2, a rotating shaft 5 fixedly connected to the top of the base body 4, and the end of the rotating shaft 5 extending into the cavity 3.

[0027] The inner wall of the cavity 3 is provided with a first limiting groove 6, a limiting block 7 is provided on one side of the first limiting groove 6, an elastic rod 9 is connected to the outer wall of the rotating shaft 5, a limiting protrusion 10 is fixedly installed on the elastic rod 9, a spring buckle 11 is connected to the adjacent side of the limiting protrusion 10, and the bottom of the elastic rod 9 extends to the bottom of the base body 4.

[0028] The outer wall of the rotating shaft 5 has a first guide groove 12 with a longitudinal structure, and the outer side of the rotating shaft 5 has a second guide groove 13 with a transverse structure. The first guide groove 12 and the second guide groove 13 are connected. The inner wall of the storage groove 2 has a second limiting groove 8 for use with the snap 11.

[0029] Specifically, when the LCD TV stand needs to be used, first manually pull out the stand body 4 so that the stand body 4 gradually separates from the outside of the storage slot 2. During the process of pulling out the stand body 4 downward, the rotating shaft 5 connected to the top of the stand body 4 moves synchronously. The spring buckle 11 on the elastic rod 9 on the outer wall of the rotating shaft 5 will pass through the first limiting groove 6 opened in the inner wall of the cavity 3. Since the size of the spring buckle 11 is larger than the first limiting groove 6 and the spring buckle 11 is located on the elastic rod 9, the spring buckle 11 passes through the first limiting groove 6 without obstruction. At the same time, the limiting protrusion 10 on the elastic rod 9 will fall into the first limiting groove 6. The limiting protrusion 10 is a conical surface. When the rotating shaft 5 is subjected to a large rotational force, the limiting protrusion 10 can disengage from the first limiting groove 6.

[0030] After completing the above steps, rotate the base body 4 to drive the rotating shaft 5 to rotate 90 degrees. During this process, the snap 11 will gradually fall into the second limiting groove 8 opened in the inner wall of the storage groove 2, and the limiting block 7 on the inner wall of the cavity 3 will slide and contact the second guide groove 13 opened horizontally on the outer side of the rotating shaft 5. The rotating shaft 5 can be kept rotating smoothly by the guidance of the second guide groove 13. When the limiting block 7 and the end of the second guide groove 13 abut against each other, the snap 11 will fall into the second limiting groove 8 precisely, realizing the automatic positioning and locking of the rotation angle of the rotating shaft 5. At this time, the upper ends of both sides of the base body 4 will contact the bottom of the TV, forming a stable support structure for the LCD TV. The base operation is completed.

[0031] When the base needs to be stored, first move the elastic rod 9 at the bottom of the base body 4 to disengage the snap 11 on the elastic rod 9 from the second limiting groove 8. Then rotate the base body 4 to drive the rotating shaft 5 to rotate 90 degrees in the opposite direction. At this time, the limiting block 7 on the inner wall of the cavity 3 will enter the first guide groove 12 longitudinally opened on the outer wall of the rotating shaft 5 from the second guide groove 13. Then push the base body 4 upward to gradually fall into the storage groove 2. During the process of pushing the base body 4 upward, the limiting block 7 will slide and connect in the first guide groove 12. At the same time, the snap 11 will cross the first limiting groove 6. Then the snap 11 will continue to press the inner wall of the cavity 3. Through the pressing action of the snap 11 and the inner wall of the cavity 3, the base body 4 is stably fixed in the storage groove 2, and the base storage operation is completed.

[0032] The main body 4 of the base can be completely stored in the storage slot 2 at the bottom of the LCD TV housing 1. It will not take up extra space when not in use, which is especially suitable for small apartment environments or scenarios where the TV needs to be moved and stored frequently. It reduces the space occupation problem when the base is idle and improves space utilization. Whether it is using or storing the base, it can be done manually without the need for complicated tools such as screwdrivers and wrenches. From pulling out and rotating to positioning to pushing and storing, each step of operation is logically clear and simple.

[0033] During use, the automatic positioning and locking are achieved through the cooperation of the spring buckle 11 and the second limiting groove 8. At the same time, the sliding guidance of the limiting block 7 and the second guide groove 13 ensures that the rotating shaft 5 rotates smoothly. Finally, the upper ends of both sides of the base contact the bottom of the TV to form a stable support, which can effectively bear the weight of the TV and prevent the TV from tipping over. The cooperation of components such as the spring buckle 11 and the limiting protrusion 10 not only ensures smooth operation, but also maintains structural stability during use, improving safety. The connection design of the first guide groove 12 and the second guide groove 13 on the rotating shaft 5, the sliding cooperation of the limiting block 7 and the guide groove, and the precise docking of the spring buckle 11 and the limiting groove realize the automatic positioning of the base rotation angle. There is no need for the user to manually adjust and calibrate, ensuring that the base is accurately positioned and forms a stable support every time it is used.

[0034] The base body 4 has a semi-arc structure. The storage groove 2 fits the base body 4. The storage groove 2 also has a semi-arc structure. The limiting protrusion 10 has a conical structure. The limiting protrusion 10 is smaller than the spring buckle 11. The spring buckle 11 is larger than the first limiting groove 6. The first guide groove 12 and the second guide groove 13 have an L-shaped cross section.

[0035] Specifically, when using the base, first manually pull out the semi-circular base body 4. Since the storage slot 2 and the base body 4 are also semi-circular, they are highly compatible and can reduce the jamming when pulling out, allowing the base body 4 to smoothly detach from the storage slot 2.

[0036] During the removal process, the rotating shaft 5 at the top of the base body 4 moves synchronously. The spring buckle 11 on the elastic rod 9 on the outer wall of the rotating shaft 5 will pass over the first limiting groove 6 on the inner wall of the cavity 3. Since the spring buckle 11 is larger than the first limiting groove 6 and has elasticity, it passes over without obstruction. At the same time, the conical limiting protrusion 10, which is smaller than the spring buckle 11, will fall into the first limiting groove 6. Then, the base body 4 is rotated to drive the rotating shaft 5 to rotate 90 degrees. At this time, the first guide groove 12 and the second guide groove 13, which have an L-shaped cross section and are interconnected, will slide the limiting block 7 on the inner wall of the cavity 3 along the second guide groove 13. The L-shaped guide groove has a regular structure, which can ensure that the rotating shaft 5 rotates smoothly. When the limiting block 7 touches the end of the second guide groove 13, the spring buckle 11 falls precisely into the second limiting groove 8 on the inner wall of the storage groove 2, realizing automatic positioning and locking. The upper ends of both sides of the semi-circular base body 4 contact the bottom of the TV to form a stable support. The operation is completed.

[0037] When storing, move the elastic rod 9 at the bottom of the base body 4 to disengage the snap 11 from the second limiting groove 8. Rotate the base body 4 in the opposite direction to drive the rotating shaft 5 to rotate back 90 degrees. The limiting block 7 slides into the longitudinal part along the horizontal part of the L-shaped guide groove. Then push the base body 4 upward. The semi-circular base body 4 fits into the storage groove 2. The pushing process is smooth. The base body 4 gradually falls into the storage groove 2. During the pushing, the limiting block 7 slides along the first longitudinal guide groove 12. After the snap 11 passes the first limiting groove 6, it continues to squeeze the inner wall of the cavity 3. Finally, the base body 4 is stably fixed in the storage groove 2, and the storage operation is completed.

[0038] The base body 4 and the storage slot 2 are both semi-circular and fit together, reducing structural friction and jamming when pulling out and storing. The L-shaped guide slot structure is regular, and the limiting block 7 has strong sliding guidance, ensuring that the rotating shaft 5 rotates and moves smoothly and avoiding operation obstruction. The tapered limiting protrusion 10 facilitates temporary limiting and subsequent disengagement. The spring buckle 11 is designed to be larger than the first limiting slot 6, which can not only ensure that it can be stably inserted into the second limiting slot 8 during use, but also achieve fixation by squeezing the inner wall of the cavity 3 during storage. The size and shape of the components are reasonably matched to avoid loosening or falling off during use.

[0039] The working principle of this utility model is as follows:

[0040] First, the storage base is formed by the storage groove 2 opened at the bottom of the LCD TV housing 1 and the base body 4 installed inside it. The rotating shaft 5 fixed at the top of the base body 4 extends into the cavity 3 connected to the top of the storage groove 2. The first limiting groove 6 and the limiting block 7 on the inner wall of the cavity 3, together with the elastic rod 9 on the outer wall of the rotating shaft 5, the conical limiting protrusion 10 and the spring buckle 11 on the elastic rod 9, as well as the longitudinal first guide groove 12 and the transverse second guide groove 13 with an L-shaped cross section connected on the rotating shaft 5, and the second limiting groove 8 on the inner wall of the storage groove 2 that cooperates with the spring buckle 11, together constitute the structural basis for the base to work, providing component support for subsequent use and storage operations.

[0041] Secondly, when the base is needed, manually pull out the base body 4 to move the rotating shaft 5. During this process, the spring buckle 11 of the elastic rod 9 can smoothly pass the first limiting groove 6 due to its elasticity and size advantage. At the same time, the conical limiting protrusion 10 falls into the first limiting groove 6 to achieve temporary limiting. Then, rotate the base body 4 to drive the rotating shaft 5 to rotate 90 degrees. The limiting block 7 in the cavity 3 slides along the second guide groove 13 of the rotating shaft 5. When the limiting block 7 touches the end of the second guide groove 13, the spring buckle 11 accurately engages in the second limiting groove 8 to complete the automatic positioning and locking. At this time, the upper ends of both sides of the base body 4 contact the bottom of the TV to form support. The whole process realizes the functional conversion from storage to support through the sliding, engaging and guiding cooperation between the components.

[0042] Finally, during storage, first move the elastic rod 9 at the bottom of the base body 4 to disengage the snap 11 from the second limiting groove 8, rotate the shaft 5 in the opposite direction, and the limiting block 7 slides from the second guide groove 13 into the first guide groove 12. Then push the base body 4 upward, and the limiting block 7 slides along the first guide groove 12. After the snap 11 crosses the first limiting groove 6 again, it continues to press the inner wall of the cavity 3. With the help of the pressing force between the snap 11 and the inner wall of the cavity 3, the base body 4 is stably stored in the storage groove 2. The semi-circular base body 4 fits the storage groove 2, reducing friction and jamming, ensuring a smooth storage process, and realizing the reverse conversion from the support state to the storage state.

[0043] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
