Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a display device 01, as shown in fig. 1b, including a housing 10, a power line 20, and a line card 30 fixed on the housing 10. The line card 30 is used for fixing the position of the power line 20. In this case, as shown in fig. 1c, the power line is drawn from the circuit board 111 and then chucked through the line card 30. As shown in fig. 1b, a card slot 112 matching the shape of the line card 30 is provided on a housing (which may be a rear case of a television) of the display device 01, for example, a television. The card slot 112 may be disposed above or on the side of the television housing 10. In this way, after the housing 10 is fixed to the circuit board 111, the power cord can be fixed to the upper side or the side of the television housing 10 by the engagement of the card slot 112 and the line card 30, thereby facilitating the use habit of the user. In addition, the circuit board 111 is covered by the case 10, thereby enabling the case 10 to protect the circuit board 111 and improving the aesthetic appearance of the product.

Specifically, as shown in fig. 1a, the line card 30 includes a guide 101, a band-shaped locking member 102, and the guide 101 and the band-shaped locking member 102 are connected by a connecting portion 103. Wherein, the connecting portion 103, the guide 101 and the band-shaped locking member 102 may be integrally formed by a film-pressing manufacturing process.

The width B1 of the first and second connection portions 103 may be 2mm or more and 7mm or less. When the width B1 of the connecting portion 103 is less than 2mm, the requirement for the processing progress is high, and for example, a molded part is generally prepared by using a die, and the thickness thereof is 2mm or more, so when the width B1 of the connecting portion 103 is less than 2mm, it is difficult to use die press molding. Further, in the power supply lines 20 of various specifications, since the diameter of the power supply line 20 of the minimum specification is 7.4mm, if the width B1 of the connection part 103 is larger than 7mm, the ribbon lock 102 is affected by the width B1 of the connection part 103, and the power supply line 20 of the minimum specification cannot be tightened. Therefore, when the width B1 of the connection part 103 is 7mm or less, the band-shaped lock 102 can tighten power cords of various specifications. Preferably, in order to increase the strength of the connection part 103, the width B1 of the connection part 103 is preferably larger within the above range of 2mm to 7 mm.

Second, the length B2 of the connection part 103 is equal to or less than the slip threshold of the power supply line 20. The slippage threshold refers to the slippage of the power cord when the pulling force within the threshold acting force range acts on the power cord. The threshold force range and the slip threshold may be adjusted according to actual needs, which is not limited in the present invention. For example, when the power cord is applied 50 times with a pull force of 50N, the slip threshold of the power cord is 5 mm.

Third, the line card 30 is fixed to the housing 10 in order to fit the line card 30 into the card slot 112. As shown in fig. 4, a concave structure 306 may be disposed on the outer surface of the guide 101, and a convex structure (not shown) matching the shape of the concave structure 306 may be disposed on the inner surface of the card slot 112 of the housing 10, so that the convex structure on the card slot 112 can be snapped into the concave structure 306 of the guide 101 to fix the guide 101 to the housing 10, and finally, the line card 30 is fitted to the card slot 112.

In addition, the guide 101 includes a first bracket 301, and a first guide slot 3011 is disposed on the first bracket 301. The power cord 20 is disposed along a guide direction of the first guide slot 3011. This guides the position of the power cord 20 in the first guide groove 301 so that the power cord 20 passes through the predetermined position. Wherein the preset position is a preset position of the wiring of the power line 20. The preset position can be adjusted according to the actual needs of the designer, for example, as shown in fig. 1b, when the power cord 20 is a power cord of a television, the preset position can be arranged below or at the side of the television housing 10, so that the power cord passing through the housing 10 can facilitate the use habit of the user.

Further, the band-shaped locking member 102 is provided at an entrance of the first guide slot 3011, and is used for fastening the power cord 20. Wherein the band-like lock 102 has two states of relaxed and locked. In the relaxed state, the ribbon lock 102 may be deployed as shown in fig. 1 a. In the locked state, as shown in fig. 1c, the band-shaped locking member 102 can tightly wrap the power cord 20 for one circle to tighten the power cord 20, so as to prevent the power cord 20 and the band-shaped locking member 102 from sliding relatively, and therefore, power cords of any specification can be tightened by the band-shaped locking member 102 to fix the position of the power cord. When the power line 20 is a power line, it can be connected to the circuit board 111 in the housing 10 for supplying power to the circuit elements in the circuit board 111.

The display device provided by the embodiment of the invention comprises a shell, a power line and a line card fixed on the shell; the line card comprises a guide part and a strip-shaped locking part, and the guide part is connected with the strip-shaped locking part through a connecting part; the guide piece comprises a first support, a first guide groove is formed in the first support, and the power line is arranged along the guide direction of the first guide groove; the strip-shaped locking piece is arranged at the inlet of the first guide groove and used for fastening the power cord.

The structure of the guide member 101 and the band-shaped lock member 102 in the wire card 30 is exemplified by specific embodiments below.

Example one

The present embodiment exemplifies the structure of the guide 101 described above.

On the basis that the guide 101 comprises the above-mentioned first bracket 301, as shown in fig. 2a, the guide 101 may further comprise a second bracket 302 and a flexible connecting member 303.

Wherein, the second bracket 302 is provided with a second guide groove 3021. As shown in fig. 2b, when the first bracket 301 is aligned with the second bracket 302, the first guide slot 3011 and the second guide slot 3021 form a guide hole for passing the power cord 20.

Furthermore, the first bracket 301 and the second bracket 302 are connected by a flexible connection 303, as shown in fig. 2 a.

Further, when the power line 20 is a power line of a television, the power line has a plurality of specifications, and among them, the power line having the largest diameter (power line in north america) has a diameter of 8.3 mm. In order to enable the guide 101 to accommodate power cords of various specifications. In the case where the first guide groove 3011 of the first bracket 301 of the guide 101 or the second guide groove 3021 of the second bracket 302 of the guide 101 has a semicircular cross-sectional shape, the diameter Φ of the first guide groove 3011 or the second guide groove 3021 may be 8.4mm to 8.6 mm.

Preferably, the diameter Φ is 8.5mm, and when the diameter Φ is greater than 8.5mm, the inner diameter of the guide hole formed by the facing arrangement of the first guide slot 3011 and the second guide slot 3021 is too large, thereby reducing the guiding effect on the position of the power cord 20. When the diameter Φ is smaller than 8.5mm, if there is a large error in the wire diameter of the power supply wire 20 having the largest wire diameter, the power supply wire 20 is not easily put into the guide hole formed by the opposing arrangement of the first guide groove 3011 and the second guide groove 3021, which is not favorable for the guide of the power supply wire 20.

Further, as shown in fig. 3, the length H of the guide 101 is 8mm to 20mm, wherein the longitudinal direction of the guide 101 is perpendicular to the extending direction of the band-shaped lock 102. When the size H is smaller than 8mm, since the size of the guide 101 is too small, it is inconvenient for a worker to hold and install, the operation difficulty is increased, and the productivity is reduced. In addition, when the dimension H is larger than 20mm, an excessively large space is occupied inside the display device body, which is not favorable for the design requirements of the compact apparatus.

The structure of the guide 101 in the present embodiment is superior to the structure of the guide 101 shown in fig. 1a in the guiding function of the power cord 20 because the second bracket 302 for engaging with the first bracket 301 of the guide 101 is provided.

In addition, in order to further improve the guiding effect of the position of the power cord 20, a self-locking mechanism may be provided between the first bracket 301 and the second bracket 302. Specifically, as shown in fig. 2a, the self-locking mechanism includes at least one locking groove 304 disposed on the first bracket 301, and at least one locking hook 305 disposed on the second bracket 302. Wherein each slot 304 is associated with a catch 305. When the first bracket 301 and the second bracket 302 are opposed to each other via the flexible connector 303, the hooks 305 may be engaged with the engaging grooves 304, so as to fix the position of the power cord 20 in the first guide slot 3011 and the second guide slot 3021.

Of course, at least one of the hooks 305 may be disposed on the first bracket 301, and the slot 304 may be disposed on the second bracket 302. The engagement method is as described above. The shapes and sizes of the hook 305 and the slot 304 are not limited, and only the first bracket 301 and the second bracket 302 are ensured not to be displaced after being clamped.

Further, as shown in fig. 2a, at least one anti-slip member 3031 is disposed on the inner walls of the first guide groove 3011 and the second guide groove 3021. Specifically, the surface a1 of the anti-slip member 3031, which is matched with the power cord 20, is serrated. The serrated surface can increase frictional resistance with the power cord 20, limiting sliding of the power cord 20 in the guide 101.

Example two

The present embodiment exemplifies the structure of the above-described band-shaped lock member 102.

The band-shaped locking member 102 may include an adjusting band 1021 and a position-limiting head 1022 connected to the adjusting band 1021 as shown in fig. 5, wherein the position-limiting head 1022 is provided with a position-limiting hole 1023 for passing through the adjusting band 1021 as shown in fig. 6, and a latch 1024 is disposed in the position-limiting hole. The surface B of the adjusting belt 1021 matched with the clamping tongue 1024 is serrated. In the process of fixing the position of the power cord 20, the adjusting strap 1021 may be passed through the limiting hole 1023, then one end of the adjusting strap 1021 is tightened, and the tongue 1024 can be snapped into the saw teeth on the surface B of the adjusting strap 1021, so as to adjust the diameter of the adjusting strap 1021 around the power cord 20, so that the diameter is gradually smaller, and finally the adjusting strap 1021 can be tightly wrapped around the power cord 20, thereby fixing the position of the power cord 20. The size of the adjusting belt 1021 around the power cord 20 can be adjusted to match different specifications of power cords 20. Therefore, the fixing mode is suitable for power cords of all specifications.

Preferably, the length L (shown in fig. 3) of the adjustment strap 1021 may be 80mm to 120 mm. When the length L of the adjustment strap 1021 is less than 80mm, the adjustment strap 1021 is too small to be pulled and locked by an installer around the power cord 20. When the length L of the adjustment tape 1021 is greater than 120mm, the length of the adjustment tape 1021 is too long, which results in an oversized whole line card, occupies too much space in the body, and is not favorable for the design requirement of the compact display device.

The width B of the adjustment belt 1021 is 2mm to 3 mm. When the width B of the adjustment belt 1021 is smaller than 2mm, the matching surface between the adjustment belt 1021 and the power cord 20 is too small, the locking force is insufficient, and the adjustment belt 1021 is too thin, which is prone to fracture in the pulling process. When the width B of the adjustment belt 1021 is larger than > 3mm, too much space is occupied in the body, and material is wasted.

It should be noted that, the first and the second strip-shaped locking pieces 102 may also be configured as shown in fig. 7, and include an adjusting belt 1021 and a limiting head 1022 connected to the adjusting belt 1021, and the limiting head 1022 is provided with a through hole 1025 for passing through the adjusting belt 1021. In fig. 7, a plurality of protrusions 1026 are disposed on a portion of the adjustment band 1021, and a plurality of small holes 1027 are disposed on a portion of the adjustment band 1021, so that when the adjustment band 1021 passes through the through hole 1025 after winding around the power line 20, a protrusion 1026 can be snapped into a small hole 1027, thereby tightly wrapping the adjustment band 1021 around the power line 20, and achieving the purpose of fixing the position of the power line 20. In the above solution, the power cord 20 with different specifications can be fixed by clamping the adjusting protrusion 1026 into different small holes.

Of course, the above is merely illustrative of the band lock 102. Other types of strip locks 102 will not be described in detail herein, but are intended to be within the scope of the present invention.

Second, the guide member 101 and the locking member 102 according to the embodiment of the present invention are coupled, so that the guide member 101 and the locking member 102 can be manufactured as an integrated structure by press molding using one mold. Thereby simplifying the manufacturing process.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
