Technical Field

[0001] The present application relates to the technical field of portable lighting equipment, and in particular to an anti-slip housing and a portable lighting equipment. Background Art

[0002] Portable lighting devices such as flashlights are usually composed of a sturdy non-slip shell, lamp beads and batteries. The non-slip shell is designed to be comfortable and easy to carry; the lamp beads provide high brightness, energy saving and long life lighting. Portable lighting devices provide reliable lighting solutions in outdoor activities, camping, emergencies and daily life, becoming practical and necessary tools.

[0003] The anti-skid housing of portable lighting equipment uses a metal anti-skid housing and is made through a metal stamping process; among them, the metal stamping process is a manufacturing method in which a metal sheet is placed in a punch press and pressed, sheared and formed using a stamping die. This process usually includes die design, material loading, impact forming and part separation steps. The stamping process can be used to produce a variety of metal parts, such as anti-skid housings for electronic devices. Its advantages are high efficiency and cost-effectiveness, and it is suitable for large-scale production. This process is widely used in the manufacturing industry and provides a reliable solution for producing metal parts with high consistency.

[0004] With the continuous pursuit of user experience, anti-skid shell texture and grip comfort of electronic products, the anti-skid shell design that improves grip comfort has become increasingly important. The anti-skid shell made by metal stamping technology is difficult to make complex anti-skid textures on the surface of the metal anti-skid shell due to mold limitations, forming difficulty and cost efficiency, and the metal anti-skid shell is usually sandblasted, brushed, coated, etc., resulting in poor anti-skid effect of portable lighting device shell.

[0005] Therefore, the prior art still needs to be improved and developed. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In view of the shortcomings of the prior art, the present application provides a non-slip housing, such as Figure 1 and Figure 2 As shown, the anti-slip shell includes a shell 1, an internal structure 2 and a protrusion 4; at least one hollow hole 3 is provided on the shell 1; the internal structure 2 is used to be arranged in the shell 1, and the assembly between the internal structure 2 and the shell 1 is a detachable assembly; the protrusion 4 is provided on the internal structure 2 and corresponds one by one to the hollow hole 3; a part of the protrusion 4 extends from the hollow hole 3 and protrudes relative to the outer surface of the shell 1.

[0034] Specifically, the protrusion 4 is connected to the internal structure 2, and the hollow hole 3 is provided on the shell 1. When the internal structure 2 is assembled with the shell 1, the protrusion 4 can correspond to the hollow hole 3 and extend outward from the hollow hole 3 to exceed the outer surface of the shell 1 (such as Figure 5 The connection between the protrusion 4 and the internal structure 2 is a detachable connection or a fixed connection; when the connection between the protrusion 4 and the internal structure 2 is a fixed connection, the protrusion 4 and the internal structure 2 can be an integrally formed structure.

[0035] When the user holds the shell 1, the hand can contact the exposed part of the protrusion 4, thereby increasing the friction between the hand and the shell 1, making it easier for the user to hold the shell 1 firmly, helping to reduce the risk of accidental sliding or loss of control, and improving the overall safety of the surface of the portable lighting device.

[0036] Since it is not easy to process the raised portion 4 of the shell 1, in the present application, the raised portion 4 for anti-slip is arranged on the internal structural member 2, and the cooperation between the internal structural member 2 and the shell 1 is utilized so that after the internal structural member 2 and the shell 1 are assembled, the raised portion 4 can be exposed and protruded from the corresponding hollow hole 3, thereby achieving anti-slip. Since the present application does not need to process the raised portion 4 of the shell 1, the process difficulty is reduced, which is conducive to the expansion of the production scale and improves the anti-slip performance.

[0037] In one embodiment of the present application, the internal structural part 2 is a plastic internal structural part and is realized by an injection molding process, which is more conducive to the production of the protrusion 4 on the internal structural part 2. For example, the protrusion 4 is made into a shape that is more conducive to the user's grip, thereby improving the user's sense of control over the entire shell 1, allowing the user to more accurately control the portable lighting device without too much effort to maintain the stability of the grip.

[0038] In one embodiment of the present application, the internal structural component 2 includes a middle frame.

[0039] In one embodiment of the present application, the shell 1 is a metal shell; the metal shell 1 is made by a stamping process to ensure the texture of the outer surface of the metal shell 1 and the comfort of holding.

[0040] The shell 1 includes a front shell 11 and a rear shell 12; the rear shell 12 cooperates with the front shell 11 and encloses a receiving space; the internal structural member 2 is located in the receiving space; and at least one hollow hole 3 is provided on each of the front shell 11 and the rear shell 12.

[0041] Correspondingly, at least one protrusion 4 is provided on the side of the internal structure 2 close to the front shell 11, and at least one protrusion 4 is also provided on the side of the internal structure 2 close to the rear shell 12. In this embodiment, protrusions 4 are arranged on both the front and rear sides of the shell 1 to improve the anti-slip performance.

[0042] The front shell 11 and the rear shell 12 are integrally formed, thereby improving the overall structural stability of the housing 1 .

[0043] Embodiment 1 of this application

[0044] At least one protrusion 4 extending along the length direction of the internal structure 2 is provided on a side of the internal structure 2 corresponding to the front shell 11 , and the protrusion 4 is close to an edge of the internal structure 2 in the width direction.

[0045] Specifically, at least one protrusion 4 is arranged on the side of the internal structure 2 corresponding to the front shell 11, and is extended along the length direction of the internal structure 2. When the user holds the shell 1, the habitual action is to hold the edge of the shell 1 in the length direction. Therefore, the protrusion 4 is arranged along the length direction of the internal structure 2 and is close to the edge of the internal structure 2 in the width direction, so that when the user holds the shell 1, the protrusion 4 is easier to contact the user's hand, and the contact area between the protrusion 4 and the user's hand can be increased as much as possible, further improving the anti-slip performance of the shell 1.

[0046] It should be noted that the length direction of the internal structure 2 is from the head to the tail of the portable lighting device, or from the tail to the head of the portable lighting device; wherein the light source of the portable lighting device emits light toward the head.

[0047] In one implementation of the present embodiment, there are multiple protrusions 4 extending along the length direction of the internal structure 2, and they are arranged in groups of two, that is, every two protrusions 4 constitute a group. The two protrusions 4 are distributed along the width direction of the internal structure 2. The width of the shell 1 is designed to be easy for the user to hold with one hand, so the protrusions 4 are provided on both sides of the width direction of the internal structure 2, and the two protrusions 4 are respectively close to the edges of the width direction of the internal structure 2, so that when the user holds the shell 1 with one hand, the two protrusions 4 can effectively contact the palm and fingertips of the user, increase the contact area, and further improve the anti-slip performance.

[0048] Embodiment 2 of this application

[0049] At least one protrusion 4 extending along the width direction of the internal structural member 2 is provided on the side of the internal structural member 2 corresponding to the front shell 11; specifically, at least one protrusion 4 extending along the width direction of the internal structural member 2 is provided on the side of the internal structural member 2 corresponding to the front shell 11.

[0050] When a user holds the portable lighting device, he or she usually holds the shell 1 with the palm of his or her hand, with the user's thumb close to the front shell 11 and extending along the length direction of the shell 1; therefore, in this embodiment, a raised portion 4 extending along the width direction of the internal structural member 2 is provided on the side of the internal structural member 2 corresponding to the front shell 11, which can increase the friction between the shell 1 and the user's thumb, thereby improving the anti-slip performance.

[0051] In one implementation of the present embodiment, there are multiple protrusions 4 extending along the width direction of the internal structural member 2, and they are arranged in groups of two, that is, every two protrusions 4 constitute a group; the two protrusions 4 are distributed along the length direction of the internal structural member 2, so that when the user holds the shell 1 with one hand, no matter the user's thumb has a tendency to slide toward the head or the tail along the length direction, there is a protrusion 4 to rub the user's thumb to prevent it from slipping, thereby ensuring the anti-slip performance of the shell 1.

[0052] Embodiment 3 of this application

[0053] The internal structural part 2 is provided with four protrusions 4 on one side corresponding to the front shell 11; among the four protrusions 4, there is a group of protrusions 4 arranged along the width direction of the internal structural part 2, and at the same time, there is a group of protrusions 4 arranged along the length direction of the internal structural part 2; and the four protrusions 4 are surrounded by a rectangular structure.

[0054] In the four protrusions 4 of this embodiment, there is a gap between every two adjacent protrusions 4, so that the hollow holes 3 corresponding to the protrusions 4 can be arranged at intervals on the shell 1 to ensure the overall strength of the shell 1.

[0055] In one embodiment of the present invention, a sink groove is further provided at a position corresponding to the rectangular structure on the front shell 11, and the hollow holes 3 corresponding to the four protrusions 4 are all located in the sink groove. The sink groove is used to cooperate with the thumb of the user, so that when the user holds the shell 1, the thumb can fit into the rectangular structure, and no matter whether the user's hand has a tendency to move along the length direction or the width direction of the shell 1, the four protrusions 4 can provide friction to the user's hand, thereby ensuring the anti-slip performance of the user's holding.

[0056] Based on any of the above embodiments, the surface of the protrusion 4 is a wavy curved surface to avoid the surface of the protrusion 4 being smooth and thus reducing the anti-slip performance. The shape and structure of the protrusion 4 extending along the width direction of the internal structural member 2 may be the same as or different from the shape and structure of the protrusion 4 extending along the length direction of the internal structural member 2 (where the length direction and the width direction are similar). Figure 2 and Figure 4 as shown).

[0057] The raised portion 4 includes a plurality of V-shaped structures 40 or the raised portion 4 includes a plurality of ribs 41; when the raised portion 4 extending along the length direction of the internal structural member 2 includes the V-shaped structure 40, the plurality of V-shaped structures 40 are sequentially arranged along the length direction of the internal structural member 2, and each adjacent two V-shaped structures 40 are partially overlapped, so that the surface of the raised portion 4 in contact with the user's hand forms a wavy curved surface instead of a smooth plane. When the raised portion 4 extending along the width direction of the internal structural member 2 includes the V-shaped structure 40, the plurality of V-shaped structures 40 are sequentially arranged along the width direction of the internal structural member 2, and each adjacent two V-shaped structures 40 are partially overlapped, so that the surface of the raised portion 4 in contact with the user's hand forms a wavy curved surface instead of a smooth plane.

[0058] At the same time, the opening of the V-shaped structure 40 is arranged toward the rear shell 12, so that the tip of the V-shaped structure 40 is arranged toward the front shell 11, which is more conducive to the protrusion 4 to contact with the user's holding fingers, thereby increasing friction.

[0059] The angle of the V-shaped structure 40 is 130°~140°, which can ensure the anti-slip performance generated by its contact with the user's hand, and will not make the contact surface between the protrusion 4 and the user's hand too sharp, thereby ensuring the comfort of holding the protrusion 4.

[0060] When the raised portion 4 extending along the width direction of the internal structural member 2 includes the ribs 41, multiple ribs 41 are distributed along the width direction of the internal structural member 2, and there is a gap between every two adjacent ribs 41; when the raised portion 4 extending along the length direction of the internal structural member 2 includes the ribs 41, multiple ribs 41 are distributed along the width direction of the internal structural member 2, and there is a gap between every two adjacent ribs 41.

[0061] The following describes the structure of the protrusion 4 by taking the difference between the shape structure of the protrusion 4 extending along the width direction of the internal structural member 2 and the shape structure of the protrusion 4 extending along the length direction of the internal structural member 2 as an example:

[0062] like Figure 3 As shown, for the raised portion 4 extending along the length direction of the internal structural member 2, the raised portion 4 includes a plurality of V-shaped structures 40, and the plurality of V-shaped structures 40 are arranged in sequence along the length direction of the internal structural member 2, and each two adjacent V-shaped structures 40 are partially overlapped, so that the surface of the raised portion 4 that contacts the user's hand constitutes a wavy curved surface rather than a smooth plane.

[0063] At the same time, the opening of the V-shaped structure 40 is arranged toward the rear shell 12, so that the tip of the V-shaped structure 40 is arranged toward the front shell 11, which is more conducive to the protrusion 4 to contact with the user's holding fingers, thereby increasing friction.

[0064] The angle of the V-shaped structure 40 is 130°~140°, which can ensure the anti-slip performance generated by its contact with the user's hand, and will not make the contact surface between the protrusion 4 and the user's hand too sharp, thereby ensuring the comfort of holding the protrusion 4.

[0065] For the protrusion 4 extending along the width direction of the internal structure 2, as shown in FIG. Figure 4 As shown, the protrusion 4 includes a plurality of ribs 41, and the plurality of ribs 41 are distributed along the width direction of the internal structure 2, and there is a gap between each two adjacent ribs 41. In order to facilitate the user's grip, the width of the internal structure 2 is designed to be relatively small. Therefore, in the present application, the protrusion 4 extending along the width direction of the internal structure 2 is designed to be an integral structure composed of a plurality of ribs 41, which is more convenient for the arrangement of the protrusion 4 on the internal structure 2 and simplifies the processing technology.

[0066] Based on the third embodiment, two protrusions 4 extending along the length direction of the internal structure 2; two protrusions 4 extending along the width direction of the internal structure 2 are arranged opposite to each other and symmetrical to each other. For the two protrusions 4 extending along the width direction of the internal structure 2, an inclined surface 411 (such as Figure 4 As shown), the inclined surface 411 gradually increases from one end close to each other to the other end away from each other, so that the raised portion 4 provides anti-slip performance for the user's hand while reducing its sharp feeling, further improving the user's comfort in holding.

[0067] In one embodiment of the present application, since the rear shell 12 needs to be provided with structures such as a heat sink and a back clip, and there is less space, the internal structure 2 is provided with only one protrusion 4 on one side corresponding to the rear shell 12, and the protrusion 4 is located at one end of the length direction of the internal structure 2, such as the tail of the internal structure 2 (such as Figure 5 As shown). When a user puts the portable lighting device into a pocket, the user will insert the head downward into the pocket according to the usage habit. Therefore, in this embodiment, a protrusion 4 is provided at the tail of the internal structure 2, so that the anti-slip shell can be pushed down by the fingers through the protrusion 4 in a humanized manner, thereby avoiding accidental contact with other parts at the tail when the anti-slip shell is put into the pocket.

[0068] The present application also provides a portable lighting device, which includes the anti-slip shell as described in any one of the above items, and also includes a circuit board, a power supply and a light source; the circuit board, the power supply and the light source are all arranged in the shell 1, and the circuit board is electrically connected to the power supply and the light source respectively.

[0069] It should be understood that the application of the present application is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to this application.
