Description

Technical Field

[0001] This utility model belongs to the field of foot pad technology, and in particular relates to a foot pad assembly structure. Background Technology

[0002] Silicone feet are typically made of silicone rubber, which has a soft and elastic texture. They are commonly used to protect key components from accidental drops or abrasion. These pads not only possess good flexibility and insulation properties, but also compressibility and natural surface adhesion, enabling them to perform multiple functions such as insulation, shock absorption, and sealing. Therefore, they are widely used in the electronics and electrical appliance industries.

[0003] In existing technologies, there are several common methods for assembling silicone feet: For example, using double-sided adhesive to directly attach silicone feet to specific locations on the bottom of the product. However, the drawback of this method is that the adhesive is prone to aging and failure, and once removed, it cannot be reused. Another method is to create holes in the product and design corresponding interference structures on the feet, utilizing the elasticity of the silicone to press the feet into the product. The concentrated force at the interference points ensures a tight fit and prevents loosening. However, this method requires considerable pressure to assemble the feet. Utility Model Content

[0004] In view of this, the present invention provides a foot pad assembly structure, which is designed to facilitate users to easily install the foot pad onto the housing and to achieve a tight connection between the two.

[0005] The technical solution of this utility model is implemented as follows:

[0006] The foot pad assembly structure provided by this utility model includes a shell and a foot pad. The shell is provided with a mounting groove, and a mounting through hole is provided on the bottom wall of the mounting groove. The foot pad includes a foot pad body, which has a first pad end face. A connecting post is protruding on the first pad end face, and an interference protrusion is protruding on the peripheral side of the connecting post. The distance between the first pad end face and the interference protrusion is greater than the depth of the mounting through hole, so as to form a deformation avoidance gap between the bottom wall of the mounting groove and the first pad end face.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture.

[0018] In existing technologies, there are several common methods for assembling silicone feet: For example, using double-sided adhesive to directly attach silicone feet to specific locations on the bottom of the product. However, the drawback of this method is that the adhesive is prone to aging and failure, and once removed, it cannot be reused. Another method is to create holes in the product and design corresponding interference structures on the feet, utilizing the elasticity of the silicone to press the feet into the product. The concentrated force at the interference points ensures a tight fit and prevents loosening. However, this method requires considerable pressure to assemble the feet.

[0019] Therefore, the foot pad assembly structure provided by this utility model allows the foot pad to be tightly assembled onto the shell; and during assembly, only a light press is needed to assemble the foot pad into place.

[0020] Please see Figure 1 , Figure 2 and Figure 3 The rubber pad assembly structure includes a housing 1 and foot pads 2. The housing 1 is provided with a mounting groove 11. The specific shape of the mounting groove 11 is not specifically limited, as long as the top of the mounting groove 11 is open; for example, the opening of the mounting groove 11 can be rectangular, circular, polygonal, etc. The bottom wall of the mounting groove 11 is provided with a mounting through hole 12, and the mounting through hole 12 and the mounting groove 11 together penetrate the housing 1.

[0021] The foot pad 2 is used to assemble with the mounting groove 11 and mounting through hole 12 of the housing 1. The foot pad 2 can be integrally molded to improve its overall strength and stability. Simultaneously, the material of the foot pad 2 can be selected from materials with good elasticity and wear resistance, such as silicone, to ensure good performance during long-term use. The foot pad 2 includes a foot pad body 21, which has a first pad end face M1; the first pad end face M1 can be understood as the end face of the foot pad body 21 facing the housing 1. A connecting post 22 is provided on the first pad end face M1. The shape of the cross-section of the connecting post 22 is not specifically limited in this invention; for example, it can be circular, rectangular, polygonal, etc. The connection post 22 facilitates the mating assembly of the foot pad 2 with the mounting through hole 12 of the housing 1. The number of connecting posts 22 is not specifically limited in this invention; it can be one or multiple. When there are multiple connecting posts 22, there are no specific restrictions on the relative positional relationship between each connecting post 22, as long as the connecting posts 22 do not interfere with each other.

[0022] Please see Figure 2 and Figure 4 An interference protrusion 23 is provided on the peripheral side of the connecting post 22; the peripheral side of the connecting post 22 can be understood as the outer surface of the connecting post 22. The interference protrusion 23 is raised relative to the outer peripheral wall of the connecting post 22. The shape of the interference protrusion 23 is not specifically limited in this utility model, for example, it can be circular, elliptical, polygonal, etc., as long as it can interfere with the inner wall of the mounting through hole 12 when the foot pad 2 is assembled. The setting of the interference protrusion 23 means that the foot pad 2 needs to overcome the interference between the interference protrusion 23 and the mounting through hole 12 (see [reference]) during the assembly process. Figure 3 The friction between the inner walls allows for a tight fit of the foot pad 2. In practice, the shape and size of the interference protrusion 23 can be designed according to actual needs to ensure that it can fit with the mounting through hole 12 (see [reference]). Figure 3 Appropriate interference occurs on the inner wall of the )

[0023] Please continue reading. Figure 2 and Figure 4 To allow the foot pad 2 to be easily installed in the mounting groove 11 and mounting through hole 12 of the housing 1, the distance between the first pad end face M1 and the interference protrusion 23 is designed to be greater than the depth of the mounting through hole 12. This creates a deformation clearance h between the bottom wall surface M3 of the mounting groove 11 and the first pad end face M1, the distance of which is... Figure 5 In this context, 'h' represents the character.

[0024] Please see Figure 5The deformation clearance h provides sufficient deformation space for the connecting post 22 and the first pad end face M1 of the foot pad 2. It can be understood that the larger the deformation space, the more conducive it is to the deformation of the foot pad 2; the more severely the foot pad 2 deforms, the easier it is for the connecting post 22 to pass through the through hole. When the user presses the foot pad 2, the connecting post 22 first enters the mounting through hole 12. At this time, the interference protrusion 23 interferes with the inner wall of the mounting through hole 12, requiring the user to apply a certain pressure to deform the connecting post 22 and the first pad end face M1 within the mounting through hole 12. As the foot pad 2 is further assembled, the connecting post 22 gradually passes through the mounting through hole 12 until the first pad end face M1 contacts the bottom wall M3 of the mounting groove 11. At this point, due to the existence of the deformation clearance h, the connecting post 22 and the first pad end face M1 of the foot pad 2 spring back and return to their original shape, thus achieving a tight assembly between the foot pad 2 and the housing 1. Meanwhile, the setting of the interference protrusion 23 also ensures that the foot pad 2 will not loosen after assembly, thus improving the stability of the assembly.

[0025] The foot pad 2 assembly structure provided by this utility model includes a housing 1 and a foot pad 2. The housing 1 is provided with a mounting groove 11, and a mounting through hole 12 is provided on the bottom wall surface M3 of the mounting groove 11. The foot pad 2 includes a foot pad body 21, which has a first pad end face M1. A connecting post 22 protrudes from the first pad end face M1, and an interference protrusion 23 protrudes from the peripheral side surface of the connecting post 22. The distance between the first pad end face M1 and the interference protrusion 23 is greater than the depth of the mounting through hole 12, so that a deformation clearance gap h is formed between the bottom wall surface M3 of the mounting groove 11 and the first pad end face M1. Through the arrangement of the mounting groove 11, the mounting through hole 12, the connecting post 22, and the interference protrusion 23, this utility model ensures that when the connecting post 22 passes through the mounting through hole 12, the connecting post 22 will gradually pass through the mounting through hole 12 and drive the foot pad body 21 to move into the mounting groove 11. Furthermore, by setting the distance between the first pad end face M1 and the interference protrusion 23 to be greater than the depth of the mounting through hole 12, a clearance gap is formed between the bottom wall surface M3 of the mounting groove 11 and the first pad end face M1. Due to the existence of the deformation clearance gap h, the user only needs to apply light force for the connecting post 22 and the first pad end face M1 of the foot pad 2 to undergo elastic deformation, thereby entering the mounting groove 11 and the mounting through hole 12. When the external force is removed, the connecting post 22 and the first pad end face M1 of the foot pad 2 will return to their original shape. Due to the setting of the interference protrusion 23, the foot pad 2 will be tightly fitted onto the housing 1 and will not easily loosen. Therefore, the setting of the deformation clearance gap h allows the user to press the connecting post 22 into the mounting through hole 12 with only light force when assembling the foot pad 2 onto the housing 1. At the same time, the setting of the interference protrusion 23 ensures that the foot pad 2 can be tightly connected to the housing 1 after it is assembled.

[0026] In some embodiments, please refer to Figure 2In order to ensure that the foot pad body 21 can fit tightly against the edge of the mounting groove 11, the foot pad body 21 is stepped. Specifically, the foot pad body 21 is stepped to form a first pad body 211 with a larger cross section and a second pad body 212 with a smaller cross section. A stepped surface M2 is formed between the first pad body 211 and the second pad body 212, facing the housing 1, and the stepped surface M2 abuts against the housing 1; the first pad end face M1 is formed on the second pad body 212.

[0027] It is understandable that the setting of the step surface M2 allows the first pad body 211 to abut against the housing 1 along the direction of the connecting post 22 through the mounting hole 12, thereby enabling the pad body 21 to abut against the housing 1 tightly.

[0028] Further, please refer to Figure 2 and Figure 4 The outer peripheral wall of the second pad body 212 is adapted to the inner peripheral wall of the mounting groove 11, so that the outer peripheral wall of the second pad body 212 abuts against the inner peripheral wall of the mounting groove 11 along its own radial direction. During installation, when the connecting post 22 enters the mounting through hole 12, the second pad body 212 enters the mounting groove 11, while the first pad body 211 remains outside the mounting groove 11. The step surface M2 ensures that the outer peripheral wall of the second pad body 212 abuts against the housing 1, thereby increasing the mutual restraint between the foot pad 2 and the housing 1, limiting the radial movement of the foot pad 2 within the mounting groove 11. Simultaneously, the step surface M2 makes it easier for the connecting post 22 to align with the mounting through hole 12 after the second pad body 212 is installed, serving a guiding function. Because the step surface M2 increases the number of force directions within the mutual support space between the installed foot pad 2 and the housing 1, it enhances the stability of the support. Furthermore, the second pad body 212 abuts against the inner peripheral wall of the mounting groove 11, which is equivalent to increasing the contact area between the foot pad 2 and the shell 1, thus increasing the stability of the support.

[0029] Therefore, the step design in this embodiment not only increases the contact area between the foot pad 2 and the housing 1, improving assembly stability, but also serves as a guide and positioning element, making it easier for the foot pad 2 to align with the mounting groove 11 and the mounting through hole 12 during assembly, thereby improving assembly efficiency. Simultaneously, the abutment of the step surface M2 also provides some support to the foot pad 2, enhancing its load-bearing capacity.

[0030] In some embodiments, please refer to Figure 2 and Figure 4To enhance the stability of the foot pad body 21, the thickness of the first foot pad body 211 is greater than the thickness of the second foot pad body 212. This allows the first foot pad body 211 to provide better cushioning and shock absorption, thereby enhancing the protective function of the foot pad 2. In practical implementation, the thicknesses of the first foot pad body 211 and the second foot pad body 212 can be designed according to actual needs to ensure that the foot pad 2 can meet different usage requirements.

[0031] In some embodiments, please refer to Figure 2 The interference protrusion 23 is arranged in a ring shape. In this way, the interference protrusion 23 can interfere with the inner wall of the mounting through hole 12 along the circumferential direction of the connecting post 22, thereby further improving the stability and tightness of the assembly between the foot pad 2 and the housing 1. The ring-shaped interference protrusion 23 ensures that the foot pad 2 is evenly subjected to the compressive force of the inner wall of the mounting through hole 12 during assembly, thus preventing the foot pad 2 from becoming misaligned or stuck during assembly. At the same time, the ring-shaped interference protrusion 23 also increases the contact area between the foot pad 2 and the housing 1, further improving the stability and firmness of the assembly.

[0032] In addition, please see Figure 2 and Figure 3 The annular interference protrusion 23 also serves as a guide and positioning element. When installing the foot pad 2, the annular interference protrusion 23 initially contacts the inner wall of the mounting through hole 12, guiding the connecting post 22 of the foot pad 2 into the mounting through hole 12 correctly. As the foot pad 2 is further assembled, the annular interference protrusion 23 gradually and completely conforms to the inner wall of the mounting through hole 12, ensuring that the foot pad 2 can be accurately assembled into the mounting groove 11 and mounting through hole 12 of the housing 1.

[0033] To further optimize the assembly effect of the foot pad 2, the shape and size of the interference protrusion 23 can be further designed in this embodiment of the invention. For example, the interference protrusion 23 can be designed as a cone (e.g., Figure 5 (As shown), arc or other shapes, to adapt to different assembly requirements and the structure of the housing 1. At the same time, the height and width of the interference protrusion 23 can be adjusted according to actual needs to ensure that it can have appropriate interference with the inner wall of the mounting through hole 12, thereby achieving a tight assembly of the foot pad 2.

[0034] In some embodiments, please refer to Figure 3 and Figure 5Along the direction away from the first pad end face M1, the protrusion height of the interference protrusion 23 is first increased and then decreased. The gradually increasing protrusion height allows the interference protrusion 23 to gradually interfere with the inner wall of the mounting through hole 12 during the assembly of the foot pad 2, enabling the connecting post 22 of the foot pad 2 to gradually deform and smoothly pass through the mounting through hole 12. This design not only reduces the resistance of the foot pad 2 during assembly but also allows the foot pad 2 to better return to its original shape after assembly, resulting in a tighter assembly. The gradually decreasing protrusion height allows the end of the interference protrusion 23 to better fit with the edge of the mounting through hole 12 after the foot pad 2 is assembled, avoiding gaps between the end of the interference protrusion 23 and the edge of the mounting through hole 12, further improving the stability and tightness of the assembly.

[0035] Meanwhile, this gradually increasing and then decreasing protrusion height setting also allows the interference protrusion 23 to provide a sensing function for the user during assembly. When the gradually increasing interference protrusion 23 is within the mounting through hole 12, the user needs to overcome resistance to allow the connecting post 22 to pass through the mounting through hole 12; when the gradually decreasing interference protrusion 23 is within the mounting through hole 12, the user does not need to overcome resistance to allow the connecting post 22 to continue passing through the mounting through hole 12. Therefore, the user can judge whether the foot pad 2 is installed correctly based on the change in force applied.

[0036] In some embodiments, please refer to Figure 5 The interference protrusion 23 has a first conical surface 231 and a second conical surface 232 arranged adjacent to each other. In the direction away from the first pad end face M1, the inclination angle of the first conical surface 231 is greater than the inclination angle of the second conical surface 232. The first conical surface 231 is close to the first pad end face M1, and the second conical surface 232 is away from the first pad end face M1.

[0037] Therefore, please refer to Figure 3 and Figure 5 In the initial stage of foot pad 2 assembly, the second conical surface 232 first contacts the inner wall of the mounting through hole 12. Due to the small inclination angle of the second conical surface 232, it can quickly guide the connecting post 22 of the foot pad 2 into the mounting through hole 12, and cause the interference protrusion 23 to begin interfering with the inner wall of the mounting through hole 12. As the foot pad 2 is further assembled, the first conical surface 231 gradually contacts the inner wall of the mounting through hole 12. Due to the large inclination angle of the first conical surface 231, it can reduce the space occupied in the axial direction of the connecting post 22, which is beneficial to shortening the length of the connecting post 22. When the foot pad 2 is assembled in place, the end of the first conical surface 231 fits tightly with the edge of the mounting through hole 12, thereby ensuring the stability and tightness between the foot pad 2 and the housing 1. This design of the adjacent first conical surface 231 and the second conical surface 232 not only optimizes the assembly process of the foot pad 2, but also improves the stability and reliability of the assembly.

[0038] In some embodiments, please refer to Figure 5 The peripheral side of the connecting post 22 located between the first pad end face M1 and the interference protrusion 23 is configured as a guide slope 221 to engage with the mating slope 121 provided on the inner wall of the mounting through hole 12.

[0039] Therefore, please refer to Figure 3 and Figure 5 The guide ramp 221 further guides the connecting post 22 of the foot pad 2 to correctly enter and smoothly pass through the mounting through hole 12. The cooperation between the guide ramp 221 and the mating ramp 121 allows the connecting post 22 to gradually deform along a predetermined direction (such as the extension direction of the mounting through hole 12) during the assembly of the foot pad 2, thereby reducing assembly resistance and improving assembly efficiency. Simultaneously, the tight cooperation between the guide ramp 221 and the mating ramp 121 increases the contact area between the foot pad 2 and the housing 1, further improving the stability and firmness of the assembly. In practical implementation, the inclination angle and dimensions of the guide ramp 221 and the mating ramp 121 can be designed according to actual needs to ensure they cooperate effectively and achieve the best assembly effect.

[0040] In some embodiments, please refer to Figure 2 The foot pad 2 is manufactured as a single piece. This means that all parts of the foot pad 2, including the main body 21, connecting post 22, and interference protrusion 23, are molded in one go, without subsequent assembly or processing. This one-piece molding not only simplifies the manufacturing process of the foot pad 2 and improves production efficiency, but also ensures the overall strength and stability of the foot pad 2. Furthermore, the one-piece molding of the foot pad 2 reduces the likelihood of loosening or deformation during long-term use, thus guaranteeing its performance and lifespan.

[0041] In some embodiments, please refer to Figure 2 and Figure 3 The foot pad 2 is made of silicone. Thus, the foot pad 2 not only has good elasticity, adapting to various shapes of mounting grooves 11 and mounting through holes 12, but also provides good wear resistance and anti-aging properties, thereby ensuring the long service life of the foot pad 2. At the same time, the silicone material also has good anti-slip properties, increasing the friction between the foot pad 2 and the housing 1, further improving assembly stability. In practical implementation, appropriate silicone material and hardness can be selected according to actual needs to manufacture foot pads 2 that meet the requirements.

[0042] In some embodiments, please refer to Figure 2 and Figure 3The mounting through-holes 12 and connecting posts 22 are configured as one-to-one connection groups, with multiple connection groups in total. This multi-connection group further enhances the stability and robustness of the connection between the foot pad 2 and the housing 1. Each connection group includes a mounting through-hole 12 and a mating connecting post 22, working together to ensure that the foot pad 2 is evenly stressed and tightly connected to the housing 1. The multiple connection groups also distribute the stress on the foot pad 2 during assembly and use, thereby extending its service life. In practical implementation, the number and position of the connection groups can be set according to actual needs to achieve optimal assembly effect and stability.

[0043] In some embodiments, please refer to Figure 4 The first outer surface M4 of the foot pad body 21 is arched. That is, the first outer surface M4 is an arched curved surface. The outer surface of the foot pad 2 also includes an annular surface M5 surrounding the curved surface. Because the first outer surface M4 is arched, its edge is lower and its center is higher. Due to the lower edge height, the foot pad 2 is less likely to be accidentally scratched by the user, thereby reducing the possibility of the edge of the foot pad 2 lifting up and ensuring a tighter fit between the foot pad body 21 and the outer shell.

[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
