Figure 6 A perspective view of an electronic lock 1 according to an exemplary embodiment of the present invention is shown; Figure 7 An exploded view of a lock case assembly 10 according to an exemplary embodiment of the present invention is shown; Figure 8 A perspective view of a lock housing assembly 10 according to an exemplary embodiment of the present invention is shown, wherein the locking member 12 is in a pre-installed position; Figure 9 This diagram shows a perspective view of a lock housing assembly 10 according to an exemplary embodiment of the present invention, wherein the locking member 12 is in the final locked position.

[0040] like Figures 1 to 9 As shown, in an exemplary embodiment of this utility model, a lock housing assembly 10 is disclosed for an electronic lock 1 of a charging dock. The lock housing assembly 10 includes a lock housing 15 and a locking member 12. The lock housing 15 has a front end and a rear end opposite each other in its longitudinal direction Y, and includes a resilient engagement member 11 adapted to engage with a mounting bracket 3 of the charging dock to connect the lock housing 15 to the mounting bracket 3. The locking member 12 is movably connected to the lock housing 15 in the longitudinal direction Y to a pre-installed position (e.g., Figure 8 (as shown) and final lock position (as shown) Figure 3 , Figure 4 , Figure 6 and Figure 9 Move between (as shown).

[0041] When the locking member 12 is in the pre-installed position, at least a portion of the elastic engagement member 11 can undergo elastic deformation to engage or disengage with the mounting bracket 3. When the locking member 12 is in the final locked position, the locking member 12 restricts the elastic deformation of the elastic engagement member 11, thereby forming a secondary lock when the elastic engagement member 11 engages with the mounting bracket 3, preventing the elastic engagement member 11 from disengaging from the mounting bracket 3, so as to reliably hold the lock housing 15 on the mounting bracket 3, and realize the self-locking of the lock housing assembly 10 on the mounting bracket 3.

[0042] The lock housing 15 includes a pair of resiliently engaged members 11 facing each other, and the locking member 12 includes a plug portion 121 movably inserted between the pair of resiliently engaged members 11. When the locking member 12 is in the pre-installed position, at least a portion of the pair of resiliently engaged members 11 is capable of elastic deformation and movement toward each other to engage or disengage with the mounting bracket 3. When the locking member 12 is in the final locked position, the plug portion 121 restricts the movement of the pair of resiliently engaged members 11 toward each other.

[0043] The resilient coupling member 11 is formed as a cantilever, with its rear end fixedly connected to the housing wall of the lock housing 15, and its front end or near the front end having a coupling portion 111 suitable for engaging with the mating coupling portion 325 of the mounting bracket 3. The coupling portions 111 of a pair of resilient coupling members 11 are respectively provided on the opposite outer sides of the pair of resilient coupling members 11.

[0044] When the locking member 12 is in the final locked position, the plug portion 121 is located in the longitudinal direction Y between a pair of engagement portions 111 of a pair of resilient engagement members 11, with the two opposite sides 121a of the plug portion 121 respectively abutting or adjacent to the opposite inner sides 11a of the pair of resilient engagement members 11 to restrict the movement of the pair of engagement portions 111 toward each other. When the locking member 12 is in the pre-installed position, the plug portion 121 is located in the longitudinal direction Y behind the engagement portions 111 to allow the pair of engagement portions 111 to move toward each other.

[0045] Optionally, the plug portion 121 is tightly fitted with a pair of resilient couplings 11, that is, the plug portion 121 is clamped by a pair of resilient couplings 11, so that the locking member 12 can be reliably held in the pre-installed position or the final locked position when the user does not operate the locking member 12.

[0046] In the illustrated embodiment, when the locking member 12 is in the final locked position, the front end of the plug portion 121 extends forward relative to the front end of the resilient engagement member 11. However, the present invention is not limited to the illustrated embodiment. For example, in other embodiments, when the locking member 12 is in the final locked position, the front end of the plug portion 121 may be flush with the front end of the resilient engagement member 11 or slightly recessed relative to the front end of the resilient engagement member 11.

[0047] See also Figures 1 to 9 The two opposing sides 121a of the plug portion 121 and the inner sides 11a of the pair of resilient couplings 11 extend along the longitudinal direction Y. Thus, when the lock housing 15 is mounted on the mounting bracket 3 and when the lock housing 15 is subjected to an external force that drives it away from the mounting bracket 3, the force exerted by the lock housing 15 on the locking member 12 through the pair of resilient couplings 11 is perpendicular to the longitudinal direction Y, and therefore will not drive the locking member 12 to move along the longitudinal direction Y, so that the locking member 12 can be reliably held in its final locked position to reliably hold the lock housing 15 on the mounting bracket 3.

[0048] The joint portion 111 is formed protrudingly on the outside of the elastic joint 11, and the rear side 111b of the joint portion 111 is adapted to abut against the mating joint portion 325 to engage the joint portion 111 with the mounting bracket 3.

[0049] The front side 111a of the joint 111 includes a slope, such as an inclined plane or curved surface, which extends obliquely backward and outward from the front end of the joint 111, so that the lock housing 15 can be easily installed to the mounting bracket 3.

[0050] Specifically, in the initial stage of installing the lock housing 15 onto the mounting bracket 3, the locking member 12 is in its pre-installed position. When the engaging portion 111 of the lock housing 15 moves to the rear end of the mating engaging portion 325 of the mounting bracket 3, the rear end of the mating engaging portion 325 presses against the front side 111a of the engaging portion 111, causing the elastic engaging member 11 to be offset away from the mating engaging portion 325, making it easier for the engaging portion 111 to pass over the mating engaging portion 325. After the engaging portion 111 passes over the mating engaging portion 325, the engaging portion 111 is no longer pressed by the mating engaging portion 325, and the elastic engaging member 11 springs back, causing the rear side 111b of the engaging portion 111 to engage with the front end of the mating engaging portion 325.

[0051] The rear side 111b of the joint 111 includes a bevel that extends obliquely forward and outward from the rear end of the joint 111, so that the lock housing 15 can be easily removed from the mounting bracket 3 after the locking member 12 is moved to its pre-installed position.

[0052] Specifically, during the process of removing the lock housing 15 from the mounting bracket 3, after the locking member 12 is moved to its pre-installed position, as the lock housing 15 moves backward, the mating engagement portion 325 of the mounting bracket 3 presses against the rear side 111b of the engagement portion 111, causing the elastic engagement member 11 to be offset away from the mating engagement portion 325, making it easy for the engagement portion 111 to pass over the mating engagement portion 325 to disengage from the mating engagement portion 325.

[0053] The lock housing 15 also includes a first guide portion 16, which engages with the locking member 12 in a longitudinal direction Y and restricts the movement and rotation of the locking member 12 in the transverse direction X and the height direction Z of the lock housing 15.

[0054] The lock housing 15 also has two side walls 152 opposite each other in the transverse X direction, and a top wall 153 and a bottom wall 154 opposite each other in the vertical Z direction. The transverse X direction is perpendicular to the longitudinal Y direction, and the vertical Z direction is perpendicular to both the transverse X direction and the longitudinal Y direction.

[0055] In the illustrated embodiment, the elastic coupling 11 and the first guide portion 16 are disposed on the top wall 153 of the lock housing 15. However, the present invention is not limited to the illustrated embodiment. For example, in other embodiments, the elastic coupling 11 and the first guide portion 16 may also be disposed on the bottom wall 154 or the side wall 152 of the lock housing 15.

[0056] See also Figures 1 to 9 The first guide portion 16 includes a pair of first guide grooves 161 extending longitudinally along the Y direction, with openings 161a of the pair of first guide grooves 161 facing each other in the transverse direction X. Specifically, the first guide portion 16 includes a pair of groove sidewalls 162 and a pair of groove bottom walls 163 extending longitudinally along the Y direction. The groove sidewalls 162 extend parallel to the top wall 153 of the lock housing 15, and the groove bottom walls 163 connect the respective groove sidewalls 162 and the top wall 153 of the lock housing 15. The groove sidewalls 162, the respective groove bottom walls 163, and the top wall 153 of the lock housing 15 together define the first guide grooves 161.

[0057] The locking member 12 also includes a pair of guide mating portions 122 and a connecting portion 123. The pair of guide mating portions 122 are located on opposite left and right sides of the locking member 12 in the transverse X direction, extend along the longitudinal Y direction, and are movably engaged with a pair of first guide grooves 161. The connecting portion 123 connects between the rear ends of the pair of guide mating portions 122, and the middle portion of the connecting portion 123 in the transverse X direction is connected to the rear end of the plug portion 121.

[0058] The lock housing 15 also includes a pair of first stops 157 respectively disposed in a pair of first guide grooves 161. The guide engagement portion 122 includes an elastic arm 125 extending forward from the connecting portion 123 and having a first engagement portion 126. When the locking member 12 is in the final locked position, the first stops 157 stop the first engagement portions 126 to prevent the locking member 12 (when the user does not operate the locking member 12) from moving to the pre-installed position.

[0059] When the locking member 12 is in the final locked position, the front end of the connecting part 123 is stopped by the rear end of a pair of elastic coupling members 11.

[0060] The lock housing 15 also includes a pair of second stops 158 respectively disposed in a pair of first guide grooves 161. When the locking member 12 is in the pre-installed position, the second stops 158 stop the first mating part 126 to prevent the locking member 12 from moving to the final lock position (when the user does not operate the locking member 12).

[0061] The second stop portion 158 protrudes from the bottom of the first guide groove 161 toward the opening 161a of the first guide groove 161. The front and rear sides of the second stop portion 158 are respectively provided with a front inclined surface and a rear inclined surface, which are inclined toward the opening 161a and extend toward each other. Thus, when the user operates the locking member 12 to move it between the pre-installed position and the final locked position, the front or rear inclined surface of the second stop portion 158 presses against the first mating portion 126, causing the elastic arm 125 to be biased, making it easier for the first mating portion 126 to pass through the second stop portion 158.

[0062] The elastic arm 125 is also provided with a second mating part 127. When the locking member 12 is in the pre-installed position, the first stop part 157 stops the second mating part 127 to prevent the locking member 12 from moving backward and disengaging from the lock housing 15.

[0063] The second mating portion 127 is located at the front end of the elastic arm 125 and protrudes outward from the outer side of the elastic arm 125 opposite to the plug portion 121. The second mating portion 127 has a front bevel 127a, which extends obliquely backward and outward from the front end of the second mating portion 127. During the process of installing the locking member 12 into the first guide groove 161, the front bevel 127a can guide the locking member 12 to be inserted into the first guide groove 161 in the correct orientation, and make it easy for the second mating portion 127 to pass over the second stop portion 158 and the first stop portion 157 to reach the front of the first stop portion 157.

[0064] The second mating part 127 is also provided with a rear end slope 127b, which extends backward and outward at an angle, so that the second mating part 127 is in the shape of a barb. Thus, the second mating part 127 can more reliably hook the first stop part 157 to prevent the locking member 12 from moving backward and disengaging from the lock housing 15.

[0065] The front end face 157a of the first stop portion 157 extends obliquely backward and away from the opening 161a of the first guide groove 161, so that the first stop portion 157 can more reliably stop the second mating portion 127 to prevent the locking member 12 from moving backward and disengaging from the lock housing 15.

[0066] The first mating portion 126 protrudes from the outer side of the elastic arm 125 away from the plug portion 121. The front and rear sides of the first mating portion 126 are respectively provided with a front slope and a rear slope, which extend outwards and towards each other at an angle. Thus, when the user operates the locking member 12 to move it between the pre-installed position and the final locked position, the second stop portion 158 presses against the front or rear slope of the first mating portion 126, causing the elastic arm 125 to deflect, making it easier for the first mating portion 126 to pass through the second stop portion 158.

[0067] In the illustrated embodiment, the first mating portion 126 and the second mating portion 127 protrude outwards from the outer side of the elastic arm 125 away from the plug portion 121, and the first stop portion 157 and the second stop portion 158 are formed in the first guide groove 161, thereby making the structure of the lock housing assembly 10 more compact. However, the present invention is not limited to the illustrated embodiment. For example, in other embodiments, the first mating portion 126 and / or the second mating portion 127 may be arranged on the inner side, upper side, or lower side of the elastic arm 125, and the positions of the first stop portion 157 and / or the second stop portion 158 may be adjusted accordingly.
