Technical Field

[0001] The utility model relates to the technical field of price tag devices, in particular to a housing assembly of an electronic price tag and the electronic price tag. Background Art

[0002] An electronic price tag is a device for displaying information such as product name, price, origin, and material. It mainly includes a display screen, a housing wrapped outside the display screen, and a battery for powering the display screen. The battery is usually arranged in the housing. To facilitate battery replacement, an opening is required at the position corresponding to the battery on the housing, and a battery cover is arranged at the opening. Opening the battery cover can open the opening on the housing, and the battery can be replaced through this opening.

[0003] In view that the electronic price tag usually needs to be hung on a bracket together with the product, the electronic price tag may be collided when taking and placing the product, and may even fall to the ground. When the electronic price tag is collided, if the battery cover is accidentally opened, the battery will be exposed, and the battery may break away from the opening on the housing when collided forcefully. To avoid this situation, a complex connection structure is arranged between the battery cover and the housing of some existing electronic price tags, striving to improve the connection stability between the battery cover and the housing.

[0004] The defects of the existing battery cover and housing assembly include: a special tool is required to remove the battery cover from the housing when replacing the battery, which is inconvenient to use and reduces the battery replacement efficiency; it is difficult to replace the battery once the special tool cannot be obtained, and the use experience is poor.

[0037] This embodiment discloses a housing assembly of an electronic price tag and an electronic price tag including the housing assembly, which can be applied in, but not limited to, occasions such as shopping malls and supermarkets where goods need to be hung up for display. As Figure 1 and Figure 2 shown, the housing assembly of the electronic price tag includes a housing main body 1 and a battery cover 2. A through hole 11 for disassembling and assembling a battery is provided on the housing main body 1, and the battery cover 2 is detachably connected to the through hole 11. After being fastened, a receiving space for placing a battery (not shown) is formed between the battery cover 2 and the housing main body 1.

[0038] As Figures 3 to 9 shown, a screwing groove 21 is provided on the side surface of the battery cover 2 facing away from the housing main body 1. The screwing groove 21 is a groove-like structure with an open top, and at least includes a bottom surface and two oppositely arranged side wall surfaces. Applying force on the side wall surface of the screwing groove 21 can cause the battery cover 2 to rotate circumferentially, so that the battery cover 2 is connected to the housing main body 1 or detached from the housing main body 1.

[0039] The specific size of the screwing groove 21 is not limited, as long as it allows a force-applying object to extend into the screwing groove 21. In this embodiment, the width of the screwing groove 21 is between 2 mm and 3 mm, and most coins can be placed into the screwing groove 21. Coins are relatively common items in life and are easily obtained.

[0040] Using a coin as a force - applying object, insert its edge into the screwing groove 21. The user holds the main body of the coin and rotates the main body of the coin. The side surface of the coin edge abuts against the side wall surface of the screwing groove 21. When the force applied by the user is large enough, the battery cover 2 starts to rotate circumferentially to achieve the opening and closing of the battery cover 2, making battery replacement very convenient; there is no need to use special tools to open and close the battery cover 2, and the applicable range is wide.

[0041] To improve the fit between the coin and the shape of the screwing groove 21, the bottom surface of the screwing groove 21 is designed to be arc - shaped, and the two ends of the screwing groove 21 are closer to the side surface of the battery cover 2 facing away from the housing main body 1 than the middle part of the screwing groove 21. The bottom surface of the coin edge can fit more on the bottom surface of the screwing groove 21. When rotating the coin, the side surface of the coin edge can apply force to the side wall surface of the screwing groove 21 more stably, and the battery cover 2 rotates more smoothly.

[0042] Of course, the force - applying object can also be other items other than the coin. Any item that can be inserted into the screwing groove 21 and can apply a thrust force to the side wall surface of the screwing groove 21 is acceptable.

[0043] Based on the above - mentioned structure, a shell buckle 12 is provided on the housing main body 1, and a cover buckle 22 that cooperates with the shell buckle 12 is provided on the battery cover 2. After the battery cover 2 and the housing main body 1 are installed, the shell buckle 12 abuts against the surface of the cover buckle 22 facing the outside of the through - hole 11, which can prevent the battery cover 2 from detaching from the housing main body 1. When the electronic price tag is impacted or dropped by an external force, the matching structure of the shell buckle 12 and the cover buckle 22 can prevent the battery cover 2 from directly detaching from the housing main body 1; the frictional force between the shell buckle 12 and the cover buckle 22 can hinder the battery cover 2 from rotating circumferentially and avoid the shell buckle 12 and the cover buckle 22 from separating from each other.

[0044] The specific shapes of the shell buckle 12 and the cover buckle 22 are not limited. It is only necessary that the shell buckle 12 and the cover buckle 22 can be buckled together when the battery cover 2 rotates clockwise circumferentially and can be separated when the battery cover 2 rotates counterclockwise circumferentially.

[0045] The specific setting method of the shell buckle 12 is not limited. In this embodiment, the shell buckle 12 is provided on the wall surface of the through - hole 11. The specific setting method of the cover buckle 22 is not limited. In this embodiment, a base rib 26 is provided on the side surface of the battery cover 2 facing the housing main body 1. The base rib 26 extends from the battery cover 2 towards the housing main body 1, and the cover buckle 22 is fixedly connected to the base rib 26.

[0046] In addition to being used to install the cover buckle 22, the base rib 26 can also play a role in limiting. Specifically, the base rib 26 is annular and the diameter of the base rib 26 is smaller than the diameter of the through hole 11. When installing, the base rib 26 is inserted into the through hole 11, which can prevent the battery cover 2 from deviating from the through hole 11. In addition, a stop platform 16 is provided on the outer shell body 1, and the end of the base rib 26 abuts against the stop platform 16, which can prevent the battery cover 2 from entering the outer shell body 1 too deeply on the basis of ensuring that the battery cover 2 completely covers the through hole 11.

[0047] In order to make the force on the battery cover 2 more balanced, three shell buckles 12 are provided on the outer shell body 1. The three shell buckles 12 are distributed in a circular ring relative to the center of the through hole 11, and the three shell buckles 12 are equidistantly arranged between each other; a cover buckle 22 is provided on the battery cover 2 corresponding to each shell buckle 12. When the electronic price tag is impacted or dropped by an external force, the external force is dispersed on the components of the three groups of shell buckles 12 and cover buckles 22, and it is not easy to damage the shell buckles 12 and cover buckles 22, and the service life of the electronic price tag is longer.

[0048] On the basis of the above structure, a limiting convex block 13 is provided on one of the shell buckle 12 and the cover buckle 22, and a limiting groove 23 matched with the limiting convex block 13 is provided on the other of the shell buckle 12 and the cover buckle 22. In this embodiment, the limiting convex block 13 is provided on the shell buckle 12, and the limiting groove 23 is provided on the cover buckle 22.

[0049] After the outer shell body 1 and the battery cover 2 are assembled, the limiting convex block 13 is snapped into the limiting groove 23. The combined structure of the limiting convex block 13 and the limiting groove 23 can prevent the shell buckle 12 and the cover buckle 22 from moving relative to each other, and can avoid the shell buckle 12 and the cover buckle 22 from being accidentally separated due to vibration and external impact, which has a stronger protection ability for the battery and is safer to use.

[0050] The specific shapes of the limiting convex block 13 and the limiting groove 23 are not limited, as long as they can prevent the shell buckle 12 and the cover buckle 22 from moving relative to each other. In this embodiment, the surfaces of the limiting convex block 13 and / or the limiting groove 23 are arc-shaped. During installation, the arc-shaped limiting convex block 13 is easier to slide into the arc-shaped limiting groove 23, and the installation is more labor-saving. In order to prevent the shell buckle 12 and the cover buckle 22 from being accidentally separated, the limiting convex block 13 and the limiting groove 23 can be designed to be deeper (the depth direction is perpendicular to the contact surface of the shell buckle 12 and the cover buckle 22). The specific depths of the limiting convex block 13 and the limiting groove 23 are not limited, and a balance can be found between "the shell buckle 12 and the cover buckle 22 are buckled more smoothly" and "the shell buckle 12 and the cover buckle 22 are not easily accidentally separated".

[0051] On the basis of the above structure, one of the shell body 1 and the battery cover 2 is provided with an anti-foolproof rib 24, and the other of the shell body 1 and the battery cover 2 is provided with an anti-foolproof through hole 14 for penetrating the anti-foolproof rib 24. In this embodiment, the anti-foolproof rib 24 is provided on the battery cover 2, and the anti-foolproof through hole 14 is provided on the shell body 1.

[0052] Along the circumferential direction, the length of the fool-proof through hole 14 is greater than the length of the fool-proof rib 24, and the fool-proof rib 24 can move in the fool-proof through hole 14. During assembly, the fool-proof rib 24 is first inserted into the fool-proof through hole 14, at which time the shell buckle 12 and the cover buckle 22 are basically in a just staggered position; then the battery cover 2 is rotated along the direction in which the fool-proof through hole 14 extends, and the cover buckle 22 can be smoothly screwed into the bottom of the shell buckle 12, so that the shell buckle 12 and the cover buckle 22 can cooperate. The setting of the fool-proof rib 24 can make it easier to align the battery cover 2 with the through hole 11, thereby improving assembly efficiency.

[0053] On the basis of the above structure, one of the housing body 1 and the battery cover 2 is provided with a jacking boss 25, and the other of the housing body 1 and the battery cover 2 is provided with a jacking slope 15 matched with the jacking boss 25. In this embodiment, the jacking boss 25 is provided on the battery cover 2, and the jacking slope 15 is provided on the housing body 1.

[0054] The specific shape of the lifting boss 25 is not limited, as long as the lifting boss 25 can abut against the lifting slope 15 and slide along the lifting slope 15. Along the axial direction of the through hole 11, the lifting slope 15 has one end high and one end low, and the height difference between the high end and the low end is not limited. In this embodiment, the height difference between the high end and the low end is 0.05 mm.

[0055] During installation, the lifting boss 25 slides to the lower end along the lifting slope 15, and the outer surface of the battery cover 2 is substantially flush with the outer surface of the outer shell body 1, which does not affect the fit between the shell buckle 12 and the cover buckle 22; when the battery cover 2 is removed from the outer shell body 1, the lifting boss 25 slides to the upper end along the lifting slope 15, and the outer surface of the battery cover 2 is higher than the outer surface of the outer shell body 1. That is, the lifting slope 15 can make the battery cover 2 protrude from the outer shell body 1 through the lifting boss 25, making it easy for the user to manually remove the battery cover 2.

[0056] The specific material for preparing the battery cover 2 is not limited, as long as it has certain strength and good shaping ability. With good shaping ability, structures such as the screw-on groove 21, the cover buckle 22, the limit groove 23, the anti-fouling rib 24, the lifting boss 25 and the base convex ridge 26 can be processed; with certain strength, the battery cover 2 can be prevented from deformation and breakage due to external impact, falling, etc., and the service life is long.

[0057] In this embodiment, the battery cover 2 is made of polycarbonate (abbreviated as PC in English, also known as PC plastic) or ABS plastic. Among them, ABS plastic is a terpolymer of three monomers: acrylonitrile (A), butadiene (B), and styrene (S), and the relative contents of the three monomers can vary arbitrarily.

[0058] Note that the above is only the preferred embodiment of the present utility model and the technical principles applied. Those skilled in the art will understand that the present utility model is not limited to the specific embodiments described herein. Various obvious changes, re-adjustments, and substitutions can be made by those skilled in the art without departing from the protection scope of the present utility model. Therefore, although the present utility model has been described in detail through the above embodiments, the present utility model is not limited to the above embodiments. Without departing from the concept of the present utility model, more other equivalent embodiments can be included, and the scope of the present utility model is determined by the scope of the appended claims.
