[0038] With the advancement of technology and the emergence and development of computers, a wave of digitally recorded products has emerged, replacing traditional methods like film, videotapes, and audiotapes. We collectively refer to these products as digital products. For example, televisions, communication equipment, and mobile devices, such as smartphones and portable electronic tools like Bluetooth headsets, have all adopted digital technology to a significant degree and are collectively referred to as digital products. With the widespread adoption of digital products like smartphones and Bluetooth headsets, effective protective housings are needed to prevent scratches and damage. However, most current protective housings are made of plastic or other soft plastic materials, resulting in relatively simple structures and poor shock absorption. These products are particularly susceptible to damage from sideways drops or falls.

[0039] In order to solve the above problems, the present invention proposes a digital product protective case. In one embodiment, Figures 1 to 3As shown, the digital product protective case includes a main body 100 and a frame 200. It should be noted that the digital products mentioned here include televisions, communication equipment and mobile terminals, etc. Mobile terminals include mobile phones, tablet computers, Bluetooth headsets, etc. The structure of the digital product protective case is as follows Figures 1 to 3 As shown, Figure 1 This is a structural diagram of the main body 100 and the frame 200 before assembly. Figure 2 This is a schematic diagram of the structure after the main body 100 and the frame 200 are assembled. Figure 3 1 is a longitudinal cross-sectional view of the assembly of the main body 100 and the frame 200. Figures 1 to 3 As shown, the main body 100 includes a side frame 110 and a cover 120. The side frame 110 surrounds the outer edge of the cover 120, and the side frame 110 and the cover 120 together form a receiving cavity 130 for accommodating digital products. The cover 120 includes a back cover 122. The side of the receiving cavity 130 opposite to the back cover 122 is open to facilitate the placement of digital products. Figure 3 As shown, a groove 140 is formed on the side of the side frame 110 adjacent to the accommodating cavity 130. The frame 200 covers the surface opening of the groove 140. A closed airbag 300 is formed between the frame 200 and the groove 140. The closed airbag 300 is formed inside the protective shell. In a specific embodiment, the frame 200 is covered by a dispensing process to cover the surface opening of the groove 140.

[0040] In addition, if Figure 1 and Figure 2 As shown, the protective case is rectangular, with the corners of the side frame 110 transitioned by arcs. The side frame 110 includes a side portion 111 and an arc portion 112 connected in sequence. Both the side portion 111 and the arc portion 112 are provided with a groove 140. The frame 200 covers the surface opening of the groove 140, and a closed airbag 300 is formed between the frame 200 and the groove 140. The digital product is placed in the storage space within the main body 100, and the closed airbag 300 is arranged around the inner circumference of the side frame 110. When the digital product falls from a height or is impacted by external force, the closed airbag 300 can act as a buffer, dispersing and absorbing the impact force of the fall, effectively protecting the digital product from damage. It should be noted that, during use, digital products are generally prone to being bumped at their corners. It is understood that, in other embodiments, grooves 140 may be provided only on the four arc portions 112 at the corners of the side frame 110, with the frame 200 covering the surface openings of the grooves 140 in the arc portions 112. Furthermore, it should be noted that, in other embodiments, the side frame 110 of the protective case may be arc-shaped as a whole. In this case, grooves 140 may be provided along the entire circumference of the side frame 110, with the frame 200 covering the surface openings of the grooves 140 to enhance the impact resistance of the protective case.

[0041] In addition, if Figure 1 and Figure 2 As shown, there are more than two grooves 140, which are arranged at intervals on the side of the side frame 110 close to the accommodating cavity 130 and arranged along the circumference of the side frame 110. The number of the frame 200 is the same as the number of the grooves 140. The frame 200 is segmented and covers the surface openings of the grooves 140. A closed airbag 300 is formed between each frame 200 and each groove 140, so that each airbag 300 is independently arranged. The damage or failure of one airbag 300 will not affect the cushioning function of other airbags 300. In addition, Figure 1 and Figure 2 In the embodiment shown, different grooves 140 are closely arranged. It can be understood that in other embodiments, functional areas can be provided between different grooves 140 on the side frame 110. Functional holes or buttons can be opened on the functional areas. The functional holes are used to insert power cords, data cables or headphone plugs, or to transmit signals or sounds, or to connect hooks, etc.

[0042] In one embodiment, Figure 4 As shown, the groove 140 is continuously provided on the side of the side frame 110 close to the accommodating cavity 130, and the frame 200 is an integrally formed structure, and the frame 200 is continuously covered on the surface opening of the groove 140. In a specific embodiment, the main body 100 is made of TPU, PC, TPE and other materials and is made through an injection molding process, and the frame 200 is made of TPU, PC, TPE and other materials and is made through an injection molding process. The frame 200 is covered on the surface opening of the groove 140 through a dispensing process. By designing the frame 200 as an integrally formed structure, the manufacturing process of the frame 200 and the assembly process of the frame 200 and the main body 100 can be simplified.

[0043] In one embodiment, Figures 5 to 8 As shown, a protruding bone position 150 is provided in the groove 140. The protruding bone position 150 can be integrally formed with the side frame 110, or can be subsequently pasted into the groove 140 of the side frame 110 through a dispensing process. It should be noted that the present invention does not limit the shape and extension direction of the protruding bone position 150. In one embodiment, as shown in FIG. Figure 5 As shown, the protruding bone portion 150 can extend along the thickness direction of the side frame 110. In another embodiment, as shown in FIG. Figure 6 As shown, the protruding bone portion 150 can also extend along the length direction of the side frame 110, that is, along the circumference direction of the side frame 110. In another embodiment, as shown in FIG. Figure 8As shown, two types of protruding ribs 150 are disposed within the groove 140. One type of protruding rib 150 extends along the thickness of the side frame 110, and the other type of protruding rib 150 extends along the circumference of the side frame 110. The two types of protruding ribs 150 are arranged in a cross-wise manner to enhance the mechanical strength and impact resistance of the closed airbag 300.

[0044] exist Figure 6 In the embodiment shown, the protruding bone portion 150 extends along the length direction of the side frame 110, that is, along the circumference direction of the side frame 110. When the frame 200 covers the surface opening of the groove 140, the longitudinal cross-sectional structure of the protective shell is as follows: Figure 7 As shown, one end of the protruding bone 150 is connected to the side frame 110, and the other end is in contact with the frame 200, so that the protruding bone 150 can divide a closed airbag 300 into multiple small airbags 310. Figure 6 and Figure 7 In the illustrated embodiment, there are two protruding bone sections 150. These two protruding bone sections 150 can divide a single closed airbag 300 into three independent small airbags 310, each of which is a closed structure. Thus, the protruding bone sections 150 not only enhance the mechanical strength and impact resistance of the closed airbag 300, but also divide the single closed airbag 300 into multiple independent small airbags 310, ensuring that damage or failure of one small airbag 310 does not affect the cushioning function of the other small airbags 310.

[0045] In one embodiment, Figure 9 As shown, a resistance layer 400 is further provided on the inner wall of the end of the groove 140 of the side frame 110 that faces away from the frame 200. The resistance layer 400 can be made of materials such as TPU and TPE. The resistance layer 400 can be provided on the inner wall of the end of the groove 140 that faces away from the frame 200 through a dispensing process or a secondary injection molding process. The resistance layer 400 is used to enhance the impact resistance of the protective case together with the enclosed airbag 300, so that the protective case has a double-layer buffer layer. When the enclosed airbag 300 is damaged or fails, the resistance layer 400 still plays a buffering role, thereby making the impact resistance of the protective case stronger and more reliable.

[0046] exist Figures 1-9 In the embodiment shown, the groove 140 is formed on the side of the side frame 110 close to the accommodating cavity 130, and the closed airbag 300 is formed on the inner side of the protective shell. It is understood that in other embodiments, such as Figure 10 and Figure 11 As shown, the groove 140 can also be opened on the side of the side frame 110 away from the accommodating cavity 130, and the closed airbag 300 is formed on the outside of the protective shell. Figure 10 and Figure 11In the embodiment shown, a protruding bone portion 150 may be provided in the groove 140. The protruding bone portion 150 extends along the circumference direction of the side frame 110. When the frame 200 covers the surface opening of the groove 140, as shown in FIG. Figure 11 As shown, one end of the protruding bone 150 is connected to the side frame 110, and the other end is in contact with the frame 200, so that the protruding bone 150 can divide a closed airbag 300 into multiple small airbags 310. Figure 10 and Figure 11 In the illustrated embodiment, there are two protruding bone sections 150. These two protruding bone sections 150 can divide a single closed airbag 300 into three independent small airbags 310, each of which is a closed structure. Thus, the protruding bone sections 150 not only enhance the mechanical strength and impact resistance of the closed airbag 300, but also divide the single closed airbag 300 into multiple independent small airbags 310, ensuring that damage or failure of one small airbag 310 does not affect the cushioning function of the other small airbags 310.

[0047] In addition, Figures 1-11 In the illustrated embodiment, the side frames 110 and the back cover 122 of the main body 100 are integrally formed from the same material. The main body 100 can be made of soft rubber materials such as TPU and TPE to provide shock absorption and drop resistance, effectively dispersing and absorbing the impact of a drop of a digital product, thereby preventing damage to the digital product. It is understood that in other embodiments, only the side frames 110 of the main body 100 can be made of soft rubber materials such as TPU and TPE to increase the impact resistance and cushioning capabilities of the corners of the protective case, while the back cover 122 of the main body 100 can be made of other materials, such as PC with good transparency.

[0048] In one embodiment, Figure 12 and Figure 13As shown, the cover body 120 includes a front cover 121 and a rear cover 122 arranged opposite each other, and a side frame 110 is disposed between the front cover 121 and the rear cover 122. The main body 100 is provided with a closable opening 170 to facilitate the insertion of digital products. The main body 100 includes a first split body 161 and a second split body 162 that are detachably connected. The closable opening 170 is formed between the first split body 161 and the second split body 162. The side frame 110 of the first split body 161 has a first slot 141 on the side near the accommodating cavity 130, and the side frame 110 of the second split body 162 has a second slot and a third slot (not shown) spaced apart from each other on the side near the accommodating cavity 130. A functional area 600 is provided between the second slot and the third slot. The functional area 600 can have functional holes or buttons. The functional holes are used to insert a power cord, a data cable, or an earphone plug, or to transmit signals or sound, or to connect a hook, etc. The frame 200 includes a first frame body 210, a second frame body 220 and a third frame body 230; the first frame body 210 covers the surface opening of the first slot 141; the second frame body 220 covers the surface opening of the second slot; and the third frame body 230 covers the surface opening of the third slot.

[0049] In addition, Figure 10 and Figure 11 In the embodiment shown, a protruding bone portion 150 may be provided in the groove 140. The protruding bone portion 150 extends along the circumference direction of the side frame 110. When the frame 200 covers the surface opening of the groove 140, as shown in FIG. Figure 11 As shown, one end of the protruding bone 150 is connected to the side frame 110, and the other end is in contact with the frame 200, so that the protruding bone 150 can divide a closed airbag 300 into multiple small airbags 310. Figure 10 and Figure 11 In the illustrated embodiment, there are two protruding bone sections 150. These two protruding bone sections 150 can divide a single closed airbag 300 into three independent small airbags 310, each of which is a closed structure. Thus, the protruding bone sections 150 not only enhance the mechanical strength and impact resistance of the closed airbag 300, but also divide the single closed airbag 300 into multiple independent small airbags 310, ensuring that damage or failure of one small airbag 310 does not affect the cushioning function of the other small airbags 310.

[0050] Specifically, in Figure 12 and Figure 13 In the embodiment shown, the digital product 500 is a Bluetooth headset charging box, which is provided with a headset receiving cavity (not shown in the figure) and a headset charging position (not shown in the figure). Figure 12 and Figure 13In the illustrated embodiment, the side frame 110 of the main body 100 and the front cover 121 and back cover 122 are integrally formed using the same material. The main body 100 can be made of soft rubber materials such as TPU and TPE to provide shock absorption and drop resistance, effectively dispersing and absorbing the impact of a drop of a digital product, thereby preventing the digital product from being damaged. It is understood that in other embodiments, only the side frame 110 of the main body 100 can be made of soft rubber materials such as TPU and TPE to increase the impact resistance and cushioning capabilities of the corners of the protective case, and the front cover 121 and back cover 122 of the main body 100 can be made of other materials, such as PC materials with good transparency.

[0051] The digital product protective case of the present invention utilizes a rationally designed structure and interconnected relationship between the main body 100 and the frame 200, with the frame 200 positioned to cover the surface opening of the groove 140 of the side frame 110. This creates a closed air pocket 300 between the frame 200 and the groove 140. When a digital product falls or is impacted by an external force, the closed air pocket 300 effectively disperses and absorbs the impact of the fall, preventing damage. Furthermore, the closed air pocket 300 formed within the protective case makes the digital product protective case of the present invention lightweight and portable.

[0052] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
