Figure 2 yes Figure 1 An exploded schematic diagram of a first shell and a second shell of a shell structure. Figure 3 yes Figure 1 A schematic diagram of a shell structure in which the first shell is arranged on the second shell and the metal fixing part has not been bent. Figure 4 yes Figure 3 Schematic diagram of the metal fixing part after bending.

[0062] See also Figures 1 to 4 The housing structure 100 of this embodiment includes a first housing 110 and a second housing 120 ( Figure 2 In this embodiment, the first housing 110 is, for example, an upper housing of a vehicle lens module, and the second housing 120 is, for example, a lower housing of a vehicle lens module, but the types of applications of the housing structure 100 are not limited thereto. The thickness direction of the first housing 110 is the first direction Z.

[0063] The first housing 110 includes a first body 111 and at least one metal fixing portion 113 protruding from the first body 111. In this embodiment, the first body 111 is made of metal, and the metal fixing portion 113 is made of the same material as the first body 111 and is integrated.

[0064] Depend on Figure 2 It can be seen that in the present embodiment, the first shell 110 also includes an extension piece 112 extending from the first body 111. The number of metal fixing parts 113 corresponding to the extension piece 112 is, for example, two. The two metal fixing parts 113 are connected to opposite sides of the extension piece 112. The two metal fixing parts 113 are symmetrically arranged based on the extension piece 112 and extend in a second direction X perpendicular to the first direction Z. The metal fixing part 113 has a length La, a width Wa, and a thickness Ta. In other words, the extension piece 112 and the two metal fixing parts 113 form a set of T-shaped structures. In the present embodiment, the first body 111 is a rectangular body with a side length of L. The first body 111 has a joint surface 111a that is joined to the second shell 120. The shell structure 100 has a total of four groups of T-shaped structures extending from the four-side joint surfaces 111a of the first body 111. The length La of the metal fixing part 113 is approximately 0.3 to 0.4 times the side length L of the first body 111. In addition, by Figure 1 It can be seen that each metal fixing portion 113 includes a connecting end 114 and a movable end 115 opposite to each other. The connecting end 114 is connected to the extension member 112, and the movable end 115 is connected to the connecting end 114. The movable end 115 is far away from the extension member 112 and has a gap G ( Figure 2 ).

[0065] Depend on Figure 3 It can be seen that the second housing 120 includes a second body 121 and at least one receiving portion 122 recessed in the second body 121. Figure 2It can be seen that the thickness of the second body 121 is T1, and the thickness of the receiving portion 122 is T2, and the thickness T2 is less than the thickness T1. In this embodiment, the receiving portion 122 includes a groove 123 and a contact surface 124 located next to the groove 123. The depth Da of the groove 123 in the first direction ( Figure 4 ), the groove 123 is, for example, a rectangular groove, but the shape of the groove 123 is not limited thereto. In this embodiment, the second housing 120 has eight receiving portions 122, the number of which corresponds to the number of the metal fixing portions 113, and the thickness of the receiving portion 122 is T2 ( Figure 2 ) is equal to or slightly smaller than the gap G( Figure 2 ).

[0066] When the first housing 110 and the second housing 120 are to be fixed, Figure 3 to Figure 4 It can be seen that the first shell 110 and the second shell 120 are fixed in the fixture, and the metal fixing part 113 is bent toward the center of the second shell 120 to a position close to the corresponding abutment surface 124 of the receiving part 122 through the pressure of the device. The metal fixing part 113 is bent from the connection end 114 and close to the corresponding abutment surface 124 of the receiving part 122. Among them, the width W1' ( Figure 3 ) is equal to or slightly greater than the bending length La of the metal fixing portion 113 ( Figure 2 ), and the length Lb of the contact surface 124 ( Figure 3 ) is also equal to or slightly larger than the length La of the metal fixing portion 113, and the width Wa of the metal fixing portion 113 ( Figure 2 ) is less than or equal to Da( Figure 4 ), can also be designed to be larger than Da according to actual needs, so that the receiving portion 122 can accommodate the metal fixing portion 113. After the metal fixing portion 113 is bent, its movable end 115 is closer to the center of the second shell 120 than the connecting end 114.

[0067] Since the bent metal has greater strength, the metal fixing portion 113 can be well maintained in the receiving portion 122 and abut against the abutment surface 124 of the receiving portion 122 , so that the first housing 110 can be fixed to the second housing 120 .

[0068] In addition, by Figure 4 It can be seen that the eight metal fixing parts 113 can be close to the second body 121 in different directions after being bent, so that the second shell 120 can maintain a stable connection with the first shell 110. Of course, in other embodiments, the number and relative positions of the metal fixing parts 113 and the receiving parts 122 are not limited thereto.

[0069] like Figure 4As shown, in this embodiment, the angle θ1 between the metal fixing portion 113 and the extension piece 112 is between 90 degrees and 150 degrees. Specifically, the angle θ1 between the metal fixing portion 113 and the extension piece 112 is, for example, 90 degrees, but not limited thereto.

[0070] Compared with the existing structure that fixes the two shells by screwing, the shell structure 100 of this embodiment does not need to be fixed by screws, which can save the design of screw hole seats and increase the internal usable space. Alternatively, the overall volume of the shell structure 100 can be reduced.

[0071] Figure 5 It is a schematic diagram of a shell structure of another embodiment of the present invention. Figure 6 yes Figure 5 Schematic diagram of the second shell of the shell structure. Figure 7 yes Figure 5 A partially enlarged schematic diagram of the shell structure from other perspectives.

[0072] See also Figures 5 to 7 The main difference between the housing structure 100a of this embodiment and the housing structure 100 of the previous embodiment is that in this embodiment, the groove 123a is a trapezoidal groove, and the width W11 of the opening of the groove 123a is greater than the width W12 of the opening of the groove 123a (W11>W12). Of course, in other embodiments, the groove 123a can also be a rectangular groove or a triangular groove, and the shape of the groove 123a is not limited to this. Due to the change in the shape of the groove 123a, the angle θ2 ( Figure 5 ) also changes accordingly, and the angle θ2 is, for example, 135 degrees, but the angle θ2 is not limited to this.

[0073] Similarly, since the bent metal has greater strength, the metal fixing portion 113 can be well maintained in the receiving portion 122a and abut against the abutment surface 124a of the receiving portion 122a. The abutment surface 124a has a length L1 ( Figure 7 ) is greater than or equal to the length L2 of the metal fixing portion 113 ( Figure 7 In this embodiment, the metal fixing parts 113 can be bent to abut against the second body 121 in different directions, so that the second shell 120a and the first shell 110a can be firmly connected. The width W11 of the groove 123a is ( Figure 5 ) is equal to or slightly greater than the bending length L2 of the metal fixing portion 113 ( Figure 7 ), and the length L1 of the abutting surface 124a is also equal to or slightly greater than the length L2 of the metal fixing portion 113, and the width Tb of the metal fixing portion 113 ( Figure 7 ) is less than or equal to height H2( Figure 6), so that the receiving portion 122 can accommodate the metal fixing portion 113. After the metal fixing portion 113 is bent, its movable end 115 is closer to the center of the second shell 120 than the connecting end 114.

[0074] In addition, in this embodiment, the receiving portion 122a includes a bottom surface 125a, and the first body 111 is located Figure 5 The metal fixing portion 113 is located in the groove 123a below the bottom surface 125a. Figure 5 In other words, the bottom surface 125 a is between the corresponding metal fixing portion 113 and the first body 111 .

[0075] Depend on Figure 7 It can be seen that the metal fixing portion 113 has a bottom portion 116 facing the bottom surface 125a, and one of the bottom portion 116 and the bottom surface 125a is inclined. Specifically, in this embodiment, the bottom surface 125a is inclined in a direction away from the abutting surface 124a (that is, the bottom surface 125a is inclined in a direction away from the abutting surface 124a). Figure 7 The right side of the Figure 6 As shown, the height difference of the bottom surface 125a (the difference between the height H1 and H2, H1>H2) is between 0.05 mm and 0.15 mm, for example, 1 mm. The width Tb of the metal fixing portion 113 is less than or equal to the height H2, and the height H2 is less than the height H1. The angle A ( Figure 7 ) is between 90 and 150 degrees, but is not limited to this.

[0076] Such an inclined design allows the metal fixing portion 113 to first pass through the lower portion of the bottom surface 125a of the groove 123a during the bending process ( Figure 7 The right side of the middle groove 123a), and then bends toward the higher part of the bottom surface 125a of the groove 123a ( Figure 7 The metal fixing portion 113 is formed on the left side of the middle groove 123a, and interferes with the bottom 116 of the metal fixing portion 113. In other words, there is friction between the bottom 116 of the metal fixing portion 113 and the bottom surface 125a of the groove 123a near the abutment surface 124a, so that the metal fixing portion 113 can be more tightly fixed to the receiving portion 122a.

[0077] Figure 8 is a schematic diagram of another embodiment of the present invention in which the metal fixing portion has not been bent. Figure 8The metal fixing portion 113b includes a connecting end 114b and a movable end 115b opposite to each other. The connecting end 114b is connected to the extension member 112, and the movable end 115b is away from the extension member 112. In this embodiment, the width W1 of the connecting end 114b is greater than the width W2 of the movable end 115b, so that the bottom 116b of the metal fixing portion 113b is inclined. Therefore, in this embodiment, the groove 123 ( Figure 3 ) bottom surface 125( Figure 3 ) can be a non-inclined plane.

[0078] In this embodiment, since the connection end 114b has a larger width W1, the bottom 116b of the metal fixing portion 113b is lower at the connection end 114b than at the movable end 115b (closer to the bottom surface 125). Therefore, the friction between the bottom 116b of the metal fixing portion 113b and the bottom surface 125 of the groove 123 is mainly provided by the connection end 114b and the bottom surface 125 of the groove 123. Compared with the movable end 115b, the connection end 114b has better structural strength because it is connected to the extension member 112. Therefore, the design of the connection end 114b having a larger width can enable the metal fixing portion 113b to be more stably fixed to the receiving portion 122 ( Figure 3 ).

[0079] Fig. 9 It is a schematic diagram of a housing structure of another embodiment of the present invention before the first housing is assembled. Fig.10 yes Fig. 9 A schematic diagram of a shell structure in which the first shell is arranged on the second shell and the metal fixing part has not been bent. Fig.11 yes Fig.10 Schematic diagram of the appearance of the metal fixing part of the shell structure after bending. Fig.12 yes Fig.11 Schematic cross-sectional view of the shell structure.

[0080] See also Figures 9 to 12 In this embodiment, the first housing 110c of the housing structure 100c is, for example, the lower housing of the lens module, and the second housing 120c ( Fig.10 ) is, for example, an upper housing of a lens module. Of course, the types of the first housing 110c and the second housing 120c are not limited thereto.

[0081] In this embodiment, the material of the first body 111 is plastic, for example. Fig.12 It can be seen that the metal fixing part 113c is embedded in the first body 111. In addition, the shape of the metal fixing part 113c can be rectangular, and the number can be four. The second shell 120c is a rectangular body, and has a second body 121, and has four receiving parts 122c on four sides. Fig.11As shown, the four metal fixing portions 113c are bent and fixed on the four receiving portions 122c of the second shell 120c, but the shape and number of the metal fixing portions 113c are not limited thereto.

[0082] Likewise, in this embodiment, if Figures 10 to 12 Since the strength of the metal fixing part 113c increases after being bent, when the first shell 110c and the second shell 120c are to be fixed, the metal fixing part 113c only needs to be bent to abut against the abutting surface 124c of the corresponding receiving part 122c of the second shell 120c and extend into the groove 123c, wherein the width Wb of the groove 123c is slightly equal to or greater than the width Wc of the metal fixing part 113c, so that the groove 123c can receive the metal fixing part 113c. After the metal fixing part 113c is bent, the first part 126a of the metal fixing part 113c abuts against the recess 127 of the second shell 120c and then extends into the recess 123c of the first shell 110c. The recess 127 ( Fig.10 ) is less than the depth of the groove 123c, the second portion 126b and the third portion 126c of the metal fixing portion 113c extend toward the center of the first body 111 and fasten the receiving portion 122c, wherein the first portion 126a is slightly parallel to the first direction Z, the third direction Y is perpendicular to the first direction Z, and the second portion 126b and the third direction Y form an angle B ( Fig.12 ), the angle B is about 60 degrees, the third portion 126c is slightly perpendicular to the first direction Z, abuts against the abutment surface 124c of the receiving portion 122c corresponding to the second shell 120c and extends into the groove 123c. The thickness of the metal fixing member 113c is approximately equal to or less than the depth of the recess 127, and the width of the metal fixing member 113c is approximately equal to or less than the width of the recess 127.

Fig.14 yes Fig.13 Schematic diagram of other viewing angles. Fig.15 yes Fig.14 Schematic diagram of the metal fixing part of the shell structure after bending.

[0084] See also Figures 13 to 15 In this embodiment, the first shell 110d ( Fig.14 ) is, for example, the upper housing of the lens module, the second housing 120d ( Fig.14 ) is, for example, a lower shell of a lens module, and the metal fixing portion 113d is embedded in the first body 111.

[0085] In addition, the receiving portion 122d of the second shell 120d includes, for example, a groove 123d and a mating surface 124d (lower surface) of the second shell 120d. Similarly, when the first shell 110 and the second shell 120d are to be fixed, the metal fixing portion 113d is inserted into the groove 123d and the metal fixing portion 113d is bent to be mated with the mating surface 124d (lower surface) of the second shell 120d.

[0086] The first shell of the shell structure of the present invention includes at least one metal fixing portion protruding from the first body, and the second shell includes at least one receiving portion of the second body. The first shell and the second shell are fixed to the second shell by at least one metal fixing portion being bent and fitted against the at least one receiving portion. Compared with the existing structure that fixes the two shells by screw locking, the shell structure of the present invention does not need to be fixed by screws, which can save the design of the screw hole seat and increase the internal usable space. In addition, the shell structure of the present invention utilizes the property that the strength of metal increases after bending. The metal fixing portion can be stably fitted against the receiving portion after bending to maintain the fixed relationship between the two.
