DETAILED DESCRIPTION

[0028] The following is a specific embodiment of the utility model and is combined with the drawings, and the technical scheme of the utility model is further described, but the utility model is not limited to these embodiments.

[0029] Embodiment one

[0030] As Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the embodiment provides a button cell mounting structure of a digital display type refrigerant filling device, comprising a mounting base 1 and a filling shell 2, wherein the filling shell 2 is provided with a mounting cavity 21, characterized in that the mounting base 1 comprises an inner elastic side plate 12 and an outer elastic cladding plate 11, the outer elastic cladding plate 11 surrounds and fixedly connects the inner elastic side plate 12, the inner elastic side plate 12 is formed with a containing space for accommodating a button cell 3, and is provided with a gap on one side for inserting the button cell 3, the outer periphery profile of the outer elastic cladding plate 11 matches the periphery profile of the receiving part of the mounting cavity 21, and a deformation space is formed in the outer elastic cladding plate 11 for elastic deformation of the outer elastic cladding plate 11 and the inner elastic side plate 12, and the mounting base 1 is buckled and connected to the mounting cavity 21 through the outer elastic cladding plate 11.

[0031] The working principle and implementation process when in use are as follows:

[0032] First, prepare the button cell 3 to be installed and the mounting base 1, then align the button cell 3 with the gap on the inner elastic side plate 12 of the mounting base 1, and push the button cell 3 to embed it in the containing space formed by the inner elastic side plate 12 along the gap. In this process, the inner elastic side plate 12 is elastically deformed due to the extrusion of the button cell 3, and when the button cell 3 is completely inserted into the containing space, the inner elastic side plate 12 will stably and clippily embed the button cell 3 in the predetermined position due to its own elastic restoring force, and then align the outer elastic cladding plate 11 of the mounting base 1 with the button cell 3 with the mounting cavity 21 of the filling shell 2. During the insertion process, the outer elastic cladding plate 11 and the inner elastic side plate 12 may be slightly deformed due to slight extrusion, but will quickly recover to the original state, achieving a tight and stable buckling connection with the mounting cavity 21. After installation is completed, the outer surfaces of the mounting base 1 and the filling shell 2 form a smooth and seamless transition at the connection;

[0033] The disassembly process, when the mounting base 1 needs to be disassembled, only needs to be extruded or stretched by an external force to make the outer elastic cladding plate 11 deform. In this deformation process, the buckling connection between the mounting base 1 and the mounting cavity 21 is released. At this time, the mounting base 1 can be easily disassembled from the mounting cavity 21 of the filling shell 2.

[0034] By setting the gap on the inner elastic side plate 12 and forming the elastic deformation space in the outer elastic cladding plate 11, the installation and disassembly process of the button cell 3 is simplified. The installation and disassembly can be completed without complex tools or additional steps, and the connection between the mounting base 1 and the filling shell 2 forms a smooth and seamless transition, which not only improves the overall appearance of the product, but also improves the operation efficiency. The elastic clippiness design of the inner elastic side plate 12 ensures the stable installation of the button cell 3, and the tight matching of the outer elastic cladding plate 11 and the mounting cavity 21 enhances the connection stability, simplifies the maintenance process, and reduces the operation and maintenance difficulty of the user.

[0035] Embodiment Two

[0036] As shown in Figure 2 , Figure 3 the embodiment is based on Embodiment One, further comprising a guiding and positioning mechanism 4 for accurately docking and snap connecting the mounting base 1 to the mounting cavity 21 in a predetermined direction and angle.

[0037] Further, the guiding and positioning mechanism 4 comprises a lead-in portion 41 in the shape of “I” arranged on the mounting base 1 or the mounting cavity 21, and a receiving portion 42 in the shape of “Y” arranged on the mounting base 1 or the mounting cavity 21, the lead-in portion 41 and the receiving portion 42 are in plug-in cooperation.

[0038] Further, the lead-in portion 41 is provided with a clamping head 411, and the receiving portion 42 is provided with a clamping hole 421 matched with the clamping head 411, when the mounting base 1 is snap connected to the mounting cavity 21, the clamping head 411 can be clamped into the clamping hole 421.

[0039] The mounting and dismounting principle and process of the mounting base 1 are described in Embodiment One, which will not be described in this embodiment. When in use, the guiding and docking is to align the opening directions of the lead-in portion 41 and the receiving portion 42, and slowly push the mounting base 1 along the lead-in portion 41 in the shape of “I” to gradually enter the “Y” shaped path of the receiving portion 42. In this process, the lead-in portion 41 guides the mounting base 1 to dock in a predetermined direction and angle, when the lead-in portion 41 completely enters the receiving portion 42, the clamping head 411 arranged at the end of the lead-in portion 41 will naturally align and clamp into the clamping hole 421 on the receiving portion 42, the close cooperation of the clamping head 411 and the clamping hole 421, combined with the snap connection of the outer elastic covering plate 11 and the mounting cavity 21, adopts a double snap connection structure, which ensures the stable connection between the mounting base 1 and the refueling shell 2, to prevent the mounting base 1 from being accidentally touched and falling off.

[0040] The guiding and positioning mechanism 4 ensures the docking accuracy between the mounting base 1 and the refueling shell 2, avoids the installation failure caused by wrong direction or angle, and completes the installation through simple plug-in cooperation, improves the docking accuracy and installation efficiency, the close cooperation of the clamping head 411 and the clamping hole 421 enhances the connection stability between the mounting base 1 and the refueling shell 2, and the dismounting process is also simple and fast, which reduces the maintenance difficulty and cost of the user.

[0041] Referring to Figure 4 , Figure 5The embodiment is further optimized on the basis of embodiment one and embodiment two, the inner elastic side plate 12 is provided with a bottom plate 121, the inner elastic side plate 12 and the bottom plate 121 form the accommodation space, and the deformation gap 122 for the elastic deformation of the inner elastic side plate 12 is formed between the inner elastic side plate 12 and the bottom plate 121.

[0042] The bottom plate 121 is arranged at the bottom of the inner elastic side plate 12, and the inner elastic side plate 12 and the bottom plate 121 form the accommodation space for accommodating the button cell 3. The bottom plate 121 provides stable support for the button cell 3, preventing it from falling off accidentally during embedding. The deformation space formed in the outer elastic cladding plate 11 allows the inner elastic side plate 12 to elastically deform when the button cell 3 is inserted. The deformation gap 122 arranged between the inner elastic side plate 12 and the bottom plate 121 is used to allow the inner elastic side plate 12 to elastically deform inwardly after the button cell 3 is inserted, so that the inner elastic side plate 12 tightly clings to the button cell 3 by its elastic restoring force, thereby ensuring the smooth installation of the button cell 3 and optimizing the deformation design of the inner elastic side plate 12.

[0043] Further, the inner elastic side plate 12 is provided with a plurality of anti-falling pressure strips 123 extending towards the center on the periphery.

[0044] After the button cell 3 is clamped in the accommodation space, the anti-falling pressure strip 123 tightly clings to the periphery of the button cell 3, preventing it from sliding out of the accommodation space due to vibration or other external forces.

[0045] Further, as shown in Figure 4 The outer elastic cladding plate 11 is arc-shaped and symmetrically provided with a clamping portion 111 at both ends, and the inner wall of the installation cavity 21 is provided with a clamping groove 211 for clamping the clamping portion 111.

[0046] The outer elastic cladding plate 11 is arc-shaped to adapt to the curvature of the outer wall of the refilling shell 2, ensuring the fit after installation. The clamping portion 111 is arranged at both ends of the outer elastic cladding plate 11 and symmetrically distributed, used to be clamped into the clamping groove 211 of the inner wall of the refilling shell 2, realizing stable connection.

[0047] Further, the outer elastic cladding plate 11 is also symmetrically provided with a pressing portion 112 on both sides, the surface of the pressing portion 112 is rough structure, and the pressing portion 112 is located at the end of the outer elastic cladding plate 11.

[0048] The pressing part 112 is arranged on both sides of the outer elastic cladding plate 11 and is symmetrically distributed, and the user can dismount and install the base 1 by pressing the outer elastic cladding plate 11 inward with two fingers, which facilitates the user to operate. The surface of the pressing part 112 is designed as a rough structure to enhance the tactile experience of the user. The "rough structure" here refers to that the surface of the pressing part is not smooth but has certain texture or uneven characteristics. Such design can increase the friction when the finger contacts the pressing part 112, so that the user can more clearly perceive the pressing action and position during operation, thereby improving the accuracy and comfort of the user operation. The user can only install and dismount the base 1 through tactile experience, which further reduces the operation and maintenance difficulty of the user while improving the installation accuracy.

[0049] Further, the filling shell 2 is provided with a digital display platform 22 for installing a digital display screen, which is arranged downwardly inclined relative to the horizontal direction, and the digital display platform 22 covers the installation cavity 21 downwardly.

[0050] The digital display platform 22 arranged downwardly inclined relative to the horizontal direction facilitates the user to observe the digital display screen, and the digital display platform 22 covers the installation cavity 21 downwardly, thereby providing an installation position for the digital display screen and effectively protecting the components in the installation cavity 21.

[0051] Further, the installation base 1 is provided with an exchange gap 13 which can communicate the accommodation space with the space outside the installation cavity 21.

[0052] During the use of the button cell 3, due to the internal chemical reaction of the button cell 3 or the influence of external environmental factors (such as high temperature), a certain pressure may be generated in the installation cavity 21. If this pressure cannot be released in time, it may cause damage to the structure of the button cell 3, and even cause safety accidents such as explosion. Therefore, the exchange gap 13 can serve as a pressure release channel, thereby ensuring the safe use of the button cell and realizing the gas exchange between the inside and outside of the installation cavity 21.

[0053] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, without departing from the spirit of the present application or exceeding the scope defined by the appended claims.
