DETAILED DESCRIPTION

[0026] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0027] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0029] like Figure 1-Figure 5As shown, this embodiment provides a snap-fit ​​structure, including: a column 1, a mother fastener 2, a child fastener 3 and a panel member 4, wherein a first slot 101 is provided on the column; the mother fastener 2 includes a motherboard 201, a first snap-fitting portion 202 extending from the motherboard 201 toward the column 1, and the first snap-fitting portion 202 includes a locking cavity 203 toward the motherboard 201; the child fastener 3 includes a child board 301, a locking tongue 302 and a second snap-fitting portion 303, the locking tongue 302 is protruding from one side of the child board 301 opposite to the motherboard 201, and is locked in the locking cavity 203, and the second snap-fitting portion 303 is protruding from the other side of the child board 301; the panel member 4 is snap-fitted with the second snap-fitting portion 303.

[0030] Based on the above scheme, the snap-fit ​​structure mainly includes four parts, namely, a column 1, a mother fastener 2, a child fastener 3 and a panel member 4. The column 1 has a specially designed first slot 101 for tightly fitting with the mother fastener 2; the mother fastener 2 is composed of a motherboard 201 and a first snap-fitting portion 202 extending from the motherboard 201, wherein a locking cavity 203 is provided in the first snap-fitting portion 202; the child fastener 3 is composed of a child board 301, a locking tongue 302 and a second snap-fitting portion 303, wherein the locking tongue 302 protrudes from one side of the child board 301 and is specifically used for tightly locking with the locking cavity 203 of the mother fastener 2, and the second snap-fitting portion 303 is used for snapping with the panel member 4. During installation, firstly, the first clamping part 202 of the female fastener 2 is embedded in the first clamping groove 101 of the column 1 to ensure that the female fastener 2 is firmly connected to the column 1. Then, the locking tongue 302 of the sub-fastener 3 is accurately inserted into the locking cavity 203 of the female fastener 2 to achieve a firm connection between the sub-fastener 3 and the female fastener 2. Finally, the panel member 4 is clamped with the second clamping part 303 of the sub-fastener 3 to complete the entire installation process. During disassembly, only the reverse operation is required, that is, first unfasten the connection between the panel member 4 and the second clamping part 303, then separate the sub-fastener 3 and the female fastener 2, and finally remove the female fastener 2 from the column 1. The design of this buckle structure makes the installation and disassembly process very simple, without any special tools, greatly saving time and manpower; through the close fit between the lock tongue 302 and the locking cavity 203, and the stable clamping of the panel member 4 and the second clamping portion 303, the stable connection between the vertical rod and the plate body 402 is ensured, effectively preventing the generation of vibration and noise, and the stable connection reduces the damage to the equipment caused by vibration and noise, thereby extending the service life of the equipment. This buckle structure can adapt to many different types of heat pump equipment, has good versatility and adaptability, and compared with the traditional screw connection method, this buckle structure is more concise and beautiful, improving the overall appearance of the equipment.

[0031] Furthermore, the first clamping part 202 includes a main body 2021 and protrusions 2022 arranged on both sides of the main body 2021. In the design of the first clamping part 202, in addition to the main body 2021 as the main connection structure, protrusions 2022 are also arranged on both sides thereof. These protrusions 2022 not only increase the contact area between the first clamping part 202 and the column 1, but also provide an additional locking mechanism through their specific shape and position. When the first clamping part 202 of the female fastener 2 is inserted into the first slot 101 of the column 1, the main body 2021 first fits tightly with the bottom and both sides of the first slot 101 to achieve basic connection. Then, the protrusions 2022 on both sides interact with the corresponding parts of the first slot 101, and further enhance the stability and firmness of the connection through physical interference or locking. This design makes the entire connection process more stable, and also prevents the connector from loosening or falling off when subjected to external force to a certain extent.

[0032] Furthermore, the cross-section of the main body 2021 is triangular in shape. The triangular design of the main body 2021 plays a unique role in the buckle structure. First, the stability of the triangle is extremely high, which enables the main body 2021 to be more firmly fixed in the first slot 101 when inserted into the column 1. Secondly, the triangular main body 2021 can be inserted into the first slot 101 more easily. When the main body is fully inserted, the triangular structure design also increases the contact area between the last part of the main body 2021 and the first slot 101, thereby enhancing the stability and firmness of the connection. Since the main body 2021 adopts a triangular design, the connection between it and the slot is more stable. This stability can reduce the looseness and noise caused by vibration and impact during the operation of the equipment, thereby improving the operating efficiency and service life of the equipment. In addition, the triangular structure can withstand forces from all directions, so the main body 2021 adopts this design to significantly improve the bearing capacity of the connection, which enables the equipment to maintain stable operation when subjected to a large load, thereby improving the reliability and safety of the equipment; and the design of the triangular main body 2021 can make the force distribution more uniform, avoiding the problem of local stress concentration, which helps to reduce deformation and damage of structural parts and improve the durability and reliability of the connection.

[0033] In some embodiments, the panel member 4 includes a plate body 402 and a clamping member 401, wherein the clamping member 401 is mounted on the inner side wall of the plate body 402, and a second clamping slot 403 is provided on the clamping member 401 to be engaged with the second clamping portion 303. The panel member 4 not only includes the plate body 402 itself, but also has a clamping member 401 mounted on its inner side wall, and a second clamping slot 403 is specially provided on the clamping member 401 to be engaged with the second clamping portion 303, so that the entire connection process is more accurate and efficient. When installing, first ensure that the female fastener 2 and the sub-fastener 3 are properly connected to the column 1, then place the plate body 402 in a predetermined position so that the clamping member 401 on the inner side wall is aligned with the second clamping portion 303 of the sub-fastener 3, and then, through simple operations such as pressing or rotating, the second clamping portion 303 is fully entered and engaged in the second clamping slot 403. This solution ensures that the connection between the plate body 402 and the snap structure is both stable and reliable. At the same time, since the snap-in component 401 is installed on the inner wall of the plate body 402, it will not affect the appearance of the plate body 402, thus maintaining the aesthetics of the device.

[0034] It is worth mentioning that there are many options for the connection and fixing method between the plate body 402 and the clamping member 401, depending on the application requirements, material type and design considerations. The following are some optional connection methods:

[0035] Screw connection: Screw holes are pre-designed on the plate body 402 and the connector 401, and then they are fixed together using screws. This method is simple and direct and is applicable to a variety of materials and scenarios. However, it should be noted that the position and size of the screw holes need to be precisely matched to ensure the stability and aesthetics of the connection.

[0036] Bolt and nut connection: Similar to screw connection, but usually used for larger or heavier plate bodies 402. Bolts pass through holes on the plate body 402 and the clamping member 401, and then are tightened and fixed with nuts. This method provides a stronger connection force and allows a certain degree of adjustment.

[0037] Snap-on connection: The snap-on connection achieves a quick and convenient connection through the cooperation between the snap-on and the slot or hole on the plate body 402. This connection method does not require additional tools and is very simple to install and remove. However, the design needs to ensure the matching degree between the snap-on and the slot to ensure the stability of the connection.

[0038] Glue or adhesive: For some lightweight materials or occasions where a smoother appearance is required, glue or adhesive can be used to fix the plate 402 and the clamping member 401 together. However, it should be noted that it is crucial to select the right glue or adhesive to ensure the durability and reliability of the connection.

[0039] Welding: If the plate 402 and the clamp 401 are both made of metal and a very strong connection is required, welding is a better installation method. Welding can provide a permanent connection and greater stability.

[0040] Riveting: Riveting is done by inserting a rivet into a pre-designed hole and then flattening the head of the rivet with a special tool, thereby fixing the plate body 402 and the clamping member 401 together. This method is suitable for occasions that require high-strength connection.

[0041] Preferably, the female fastener 2 includes locking portions 204 disposed in the locking cavity 203 in an upper and lower manner, and a locking groove 205 for locking with the locking tongue 302 is defined between the two locking portions 204. Two locking portions 204 are disposed in the locking cavity 203 of the female fastener 2, which are opposite to each other in the vertical direction, and a locking groove 205 is defined between the two locking portions 204. The two locking portions 204 correspond to each other in the vertical direction, and a locking groove 205 is defined in the space between them. When the locking tongue 302 of the sub-fastener 3 is inserted into the locking cavity 203 of the female fastener 2, the locking tongue 302 will accurately slide into the locking groove 205. Since the shape and size of the locking groove 205 match the locking tongue 302, once the locking tongue 302 enters the locking groove 205, it will be firmly locked therein and cannot be easily dislodged. This ensures that the connection between the female fastener 2 and the sub-fastener 3 is very stable. Even under the action of external force, the connection is not easy to loosen or separate due to the close fit between the locking tongue 302 and the locking groove 205. In addition, although the locking between the female fastener 2 and the sub-fastener 3 is very stable, the installation and removal process remains simple and convenient. The installer only needs to align the locking tongue 302 with the locking groove 205 and gently push it in to achieve the connection; when disassembly is required, the locking tongue 302 can be disengaged from the locking groove 205 by applying appropriate force.

[0042] Specifically, the locking portion 204 is in an arc shape, and the corresponding locking tongue 302 is also in an arc shape, and the arc shape here can be more specifically regarded as a wave shape. Through its unique wave shape, a "bite" effect is formed during the insertion and locking process. When the locking tongue 302 is inserted into the locking cavity 203, its wavy surface will intersect and fit with the wavy surface of the locking portion 204 to form multiple contact points. These contact points not only increase the friction between the components, but also achieve locking at multiple positions at the same time through the wavy undulating shape, thereby greatly improving the stability and vibration resistance of the connection.

[0043] At the same time, the wavy arc shape design has a certain elasticity, that is, the locking portion 204 is made of elastic material, and the locking tongue 302 is made of elastic material. Such a design can adapt to a certain degree of dimensional change and shape deviation, so that the components have a higher fault tolerance rate during the manufacturing and installation process, and reduce the requirements for accuracy and fit.

[0044] In some embodiments, the first clamping portion 202 is integrally formed on the board body 402, and / or the locking tongue 302 and the second clamping portion 303 are integrally formed on the sub-board 301. Based on this solution, the following three different solutions can be combined:

[0045] The first solution: the first clamping part 202 is integrally formed on the plate body 402. By integrally forming the first clamping part 202 on the plate body 402, it can be ensured that the connection between the clamping part and the plate body 402 is very firm and not easy to loosen or fall off, thereby improving the stability and reliability of the overall structure and reducing the possible errors during the installation process. In addition, the integrally formed design also makes the entire structure more compact and more beautiful in appearance.

[0046] The second solution: the locking tongue 302 and the second clamping portion 303 are integrally formed on the sub-board 301. The integrally formed design of the locking tongue 302 and the second clamping portion 303 makes the connection between these key components on the sub-board 301 tighter and more stable. This design not only improves the overall durability and impact resistance of the sub-board 301, but also simplifies the installation and disassembly process. Since the assembly steps between multiple components are reduced, the production cost is also reduced and the production efficiency is improved.

[0047] The third solution: the first clamping portion 202 is integrally formed on the plate body 402, and the locking tongue 302 and the second clamping portion 303 are integrally formed on the sub-plate 301. Combining the above two designs, this combination solution will provide higher structural stability and connection reliability. The key components on the plate body 402 and the sub-plate 301 are manufactured by integral molding, ensuring a close connection and efficient cooperation between them. This design is particularly suitable for application scenarios that require high stability, high reliability and high efficiency, such as high-end equipment, precision instruments, etc.

[0048] In actual applications, the choice of solution depends on specific needs and scenarios. Different design solutions may differ in terms of cost, production efficiency, stability, and reliability, so it is necessary to weigh and choose according to the actual situation.
