Description

Technical Field

[0001] This application relates to the field of shaver technology, and in particular to an anti-collision structure and an electric shaver. Background Technology

[0002] With the continuous development of electric shavers, their size has become smaller and smaller, making them more convenient for users to carry. Typically, users place their shavers in suitcases or backpacks when traveling. Since suitcases and backpacks also carry other items, and compression or collisions are unavoidable during transport, the shaver's outer shell needs to have high pressure resistance to ensure the safety of internal components such as the motor, battery, and shaver head.

[0003] Furthermore, during daily use, there is a possibility that the shaver may slip from the user's hand and fall. Therefore, the outer shell of the shaver also needs to have good energy absorption and anti-collision functions to protect the safety and stability of the internal structural components.

[0004] However, most existing razor shells are made of plastic, which has poor pressure and impact resistance. When the razor is dropped or collides with other objects, the impact force is directly transmitted to the internal structural components, which can easily cause the internal structure to loosen or shift, or even cause damage to the internal structure. Utility Model Content

[0005] Therefore, it is necessary to provide an anti-collision structure and an electric shaver to address the problems mentioned above in the background art, which can at least reduce the impact force on the internal structure when a collision or compression occurs, thereby ensuring the stability of the internal structural components.

[0006] To address the aforementioned technical and other issues, according to some embodiments, one aspect of this application provides an anti-collision structure, comprising: an inner shell, an outer shell, and a cover; the inner shell includes a load-bearing shell and a support shell, the support shell being connected to the outside of the load-bearing shell, and at least a portion of the support shell forming a first energy-absorbing cavity with the load-bearing shell, an opening being formed at a first position of the load-bearing shell, the cover sealing the opening and being detachably connected to the inner shell; the outer shell being disposed at a second position of the load-bearing shell opposite to the first position, and the outer shell being connected to the inner shell, a second energy-absorbing cavity being formed between the outer shell and the load-bearing shell.

[0007] In some embodiments, the support shell includes a first shell and a second shell, the first shell and the second shell being disposed opposite each other on both sides of the bearing shell, and both the first shell and the second shell forming a corresponding first energy-absorbing cavity with the bearing shell.

[0008] In some embodiments, both the first shell and the second shell include a connecting portion and a supporting portion. The supporting shell has a protrusion formed corresponding to the center of the first shell and the center of the second shell. The connecting portion is connected to the protrusion. One end of the supporting portion is connected to the connecting portion, and the other end is connected to the edge of the supporting shell.

[0009] In some embodiments, the support portion includes a first transition section and a second transition section. One end of the first transition section is connected to the connecting portion, and the other end is connected to one end of the second transition section. The other end of the second transition section is connected to the edge of the bearing shell, and the first transition section and the second transition section are arranged at an angle.

[0010] In some embodiments, the outer shell and the inner shell are connected to form a pentagonal cross-section, and the cover and the outer shell are both connected to the inner shell to form a hexagonal cross-section.

[0011] In some embodiments, a buffer post is further included, which extends along the thickness direction of the inner housing and protrudes beyond the edge of the inner housing.

[0012] In some embodiments, there are multiple buffer pillars, and the buffer pillars are configured to correspond to the bends of the inner shell.

[0013] In some embodiments, a charging hole is formed on the inner housing and an alignment hole is formed on the outer housing, the alignment hole corresponding to the charging hole and having the same shape as the charging hole.

[0014] In some embodiments, a positioning protrusion is formed on the inner housing, and the charging hole is formed on the positioning protrusion and extends along the axial direction of the positioning protrusion; a positioning groove is formed inside the outer housing corresponding to the position of the positioning protrusion, and the positioning protrusion can be inserted into the positioning groove so that the alignment hole is aligned with the charging hole.

[0015] Another aspect of this application provides an electric shaver that includes the anti-collision structure of any of the above embodiments.

[0016] In the anti-collision structure and electric shaver of the above embodiments, the inner shell includes a support shell and a carrier shell, and the support shell and the carrier shell can form a first energy-absorbing cavity, and the outer shell can form a second energy-absorbing cavity. Therefore, when the entire electric shaver is squeezed or collided, the impact force can be relieved through the first energy-absorbing cavity and the second energy-absorbing cavity. This can reduce the problem of the impact force being directly transmitted from the external structure to the internal structure, causing the internal structure to loosen or shift, or even causing damage to the internal structure.

Unless otherwise stated, singular terms may include plural forms and should not be construed as having a quantity of one.

[0026] It should be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0027] In this application, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly.

[0028] like Figure 1 Combination Figure 2 As shown, the anti-collision structure provided in this embodiment includes an inner shell 1, an outer shell 2, and a cover 3. The inner shell 1 includes a supporting shell 101 and a supporting shell 102. The supporting shell 102 is connected to the outside of the supporting shell 101, and at least a portion of the supporting shell 102 and the supporting shell 101 form a first energy-absorbing cavity 103. An opening is formed at a first position of the supporting shell 101, and the cover 3 covers the opening and is detachably connected to the inner shell 1. The outer shell 2 is disposed at a second position opposite to the first position of the supporting shell 101, and the outer shell 2 is connected to the inner shell 1. A second energy-absorbing cavity is formed between the outer shell 2 and the supporting shell 101.

[0029] The anti-collision structure provided in this application is located outside the internal structural components of the electric shaver. That is, the bearing shell 101 in this application can form a bearing cavity, providing a bearing foundation for the electric shaver's head, battery, motor, and other structures.

[0030] Since the support shell 102 is connected to the outside of the carrier shell 101 in this application, and a first energy-absorbing cavity 103 is formed between the support shell 102 and the carrier shell 101, when the electric shaver is dropped or squeezed, the external impact force first contacts the support shell 102, and the impact force can be attenuated to a certain extent through the first energy-absorbing cavity 103. This reduces the impact force transmitted to the motor and battery installed in the carrier shell 101, thereby ensuring the stability and safety of the internal structural components of the carrier shell 101.

[0031] It is understandable that, such as Figure 3 As shown, the cover 3 in this application has a hollow structure, and when the cover 3 is fastened to the inner shell 1, a cavity is formed. Therefore, when an impact force is applied to the cover 3, it will not affect the blade structure inside the cavity, thereby enabling the entire shaver to have high pressure resistance and impact resistance.

[0032] In some embodiments, such as Figure 1 Combination Figure 2 As shown, the support shell 102 in this application includes a first shell and a second shell. The first shell and the second shell are disposed opposite to each other on both sides of the bearing shell 101, and both the first shell and the second shell form a corresponding first energy absorption cavity 103 with the bearing shell 101.

[0033] By designing the aforementioned support shell 102 on both sides of the bearing shell 101, i.e. the front and back sides of the entire electric shaver, and by ensuring that the shape and size of the first shell and the second shell in this application are consistent, the force can be distributed more evenly, thus ensuring the stability of the overall structure.

[0034] Optionally, such as Figure 1 Combination Figure 2 As shown, both the first shell and the second shell in this application include a connecting portion 1021 and a supporting portion 1022. The bearing shell 101 has a protrusion 1011 formed at the center of the first shell and at the center of the second shell. The connecting portion 1021 is connected to the protrusion 1011. One end of the supporting portion 1022 is connected to the connecting portion 1021, and the other end is connected to the edge of the bearing shell 101.

[0035] Preferably, the first shell and the second shell in this application are both symmetrical structures. The connecting part 1021 can be circular or other shapes that can fully contact the protrusion 1011. Since the protrusion 1011 is located at the center of the supporting shell 101 in this application, the connecting part 1021 is also the center of the first shell and the second shell. Accordingly, the support part 1022 in this application is connected between the connecting part 1021 and the edge of the supporting shell 101.

[0036] The connecting part 1021 enables a stable connection between the first shell and the second shell and the supporting shell 101, while the supporting part 1022 forms the first energy-absorbing cavity 103 between itself and the supporting shell 101, thereby absorbing the impact force when subjected to impact, reducing the impact on the internal electrical components, and ensuring the overall safety and stability of the shaver.

[0037] Optionally, such as Figure 1 Combination Figure 2 As shown, the support portion 1022 in this application includes a first transition section 1023 and a second transition section 1024. One end of the first transition section 1023 is connected to the connecting portion 1021, and the other end is connected to one end of the second transition section 1024. The other end of the second transition section 1024 is connected to the edge of the bearing shell 101, and the first transition section 1023 and the second transition section 1024 are set at an angle.

[0038] Preferably, such as Figure 3As shown, in this application, the outer shell 2 and the inner shell 1 are connected to form a pentagonal cross-section, and the cover 3 and the outer shell 2 are both connected to the inner shell 1 to form a hexagonal cross-section.

[0039] More preferably, the hexagonal structure constituted in this application is a regular hexagonal structure. Since hexagons are stable and the force is uniform, this application forms a regular hexagonal structure by connecting the cover 3 and the outer shell 2 to the inner shell 1. When any corner is impacted, the impact force can be uniformly transmitted to the surrounding area, thereby further improving the stability of the overall structure.

[0040] Optionally, such as Figure 2 Combination Figure 3 As shown, the anti-collision structure provided in this application also includes a buffer post 4, which extends along the thickness direction of the inner shell 1 and protrudes from the edge of the inner shell 1.

[0041] With the further designed buffer pillar 4 protruding from the edge of the inner shell 1, the impact can be made to contact the buffer pillar 4 first to a certain extent, and the buffer pillar 4 can share part of the impact force. Then the impact force is transmitted to the inner shell 1 and the outer shell 2, and the impact force is absorbed through the first energy absorption cavity 103 and the second energy absorption cavity, thereby further improving the anti-collision and anti-pressure effect.

[0042] Optionally, such as Figure 2 Combination Figure 3 As shown, there are multiple buffer pillars 4 in this application, and the multiple buffer pillars 4 are set at the angles of the inner shell 1.

[0043] Since alignment holes 201 need to be reserved at the corners of the outer shell 2 in this application to ensure the charging function, the buffer pillars 4 in this application are mainly connected at the four corners of the inner shell 1, so as to maximize the anti-collision and anti-pressure effect of the overall structure.

[0044] Optionally, such as Figures 1-3 As shown, the inner housing 1 of this application has a charging hole 1013 formed on it, and the outer housing 2 has an alignment hole 201 formed on it. The alignment hole 201 corresponds to the charging hole 1013, and the shape of the alignment hole 201 is the same as the shape of the charging hole 1013.

[0045] Preferably, such as Figure 2 As shown, in this application, a positioning protrusion 1012 is formed on the inner shell 1, and a charging hole 1013 is formed on the positioning protrusion 1012 and extends along the axial direction of the positioning protrusion 1012; a positioning groove is formed inside the outer shell 2 corresponding to the position of the positioning protrusion 1012, and the positioning protrusion 1012 can be inserted into the positioning groove so that the alignment hole 201 is aligned with the charging hole 1013.

[0046] The positioning protrusion 1012 formed by the positioning protrusion 1012 and the positioning groove formed by the corresponding positioning protrusion 1012 inside the outer shell 2 body can realize the accurate alignment and stable docking between the outer shell 2 body and the inner shell 1, and can ensure the accurate correspondence between the alignment hole 201 and the charging hole 1013, so that the plug end of the charging cable can be smoothly inserted to charge the shaver.

[0047] Another aspect of this application provides an electric shaver that includes the anti-collision structure of any of the above embodiments.

[0048] In the anti-collision structure and electric shaver of the above embodiments, the inner shell 1 includes a support shell 102 and a carrier shell 101, and the support shell 102 and the carrier shell 101 can form a first energy-absorbing cavity 103. The outer shell 2 can form a second energy-absorbing cavity by supporting the carrier shell 101. Thus, when the entire electric shaver is squeezed or collided, the impact force can be relieved through the first energy-absorbing cavity 103 and the second energy-absorbing cavity. This can reduce the problem of the impact force being directly transmitted from the external structure to the internal structure, causing the internal structure to loosen or shift, or even causing damage to the internal structure.

[0049] Please note that the above embodiments are for illustrative purposes only and do not imply any limitation on the present invention.

[0050] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0052] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
