Description

Technical Field

[0001] This utility model relates to the field of automotive charging socket technology, and in particular to a protective cover assembly and socket housing for automotive charging sockets. Background Technology

[0002] The protective cover of a car charging socket prevents dust and water droplets from entering the socket, avoiding short circuits or damage. It also seals the socket when no charging gun is inserted, preventing accidental electric shock and reducing environmental corrosion, thus extending its lifespan. To facilitate user access for charging, car charging socket covers typically feature elastic components. These elastic components, either in the opening direction of the latch or the rotation direction of the cover, provide additional opening and closing assistance, allowing the cover to automatically spring open for smoother operation.

[0003] However, the protective cover of this type of car charging socket is often deformed or broken from the socket housing due to the force of automatic pop-opening or plug insertion / removal. This results in the protective cover not being able to fit properly or failing to provide protection, increasing the product failure rate and hindering product promotion. Utility Model Content

[0004] The purpose of this utility model is to address the problem that the protective cover of the existing charging socket is often deformed by impact or broken from the socket housing, resulting in the protective cover not being able to be aligned and close or the protection failing, and to provide a protective cover assembly and socket housing for vehicle charging sockets.

[0005] To achieve the purpose of this utility model, the following solution is disclosed:

[0006] A protective cover assembly includes: a cover body, a first torsion spring, a first pin, and a first fixing seat; the cover body has a connecting rotating post at one end for connecting the first fixing seat; the first torsion spring is shaft-connected to the connecting rotating post, and the two first connecting heads of the first torsion spring respectively abut against the connecting rotating post and the first fixing seat, thereby being able to elastically twist relative to the first fixing seat;

[0007] The first pin is coaxially connected to the first torsion spring and the connecting rotating post, and both ends are fixed to the first fixing seat; the first fixing seat can fix the socket housing.

[0008] The outer wall of the connecting rotating column is provided with a first protrusion that protrudes radially outward; the first fixed seat is provided with a second protrusion that protrudes radially inward towards the connecting rotating column; the first protrusion can abut against the second protrusion in the rotational direction in which the cover body is opened, thereby limiting the cover body in the open state.

[0009] The solution described in this utility model, by setting a connecting pivot on the cover body, in conjunction with the first pin and the first torsion spring, can maintain the cover body's stable rotation and opening around the first pin, enhancing the stability of the cover body's rotation and opening. When the cover body is opened to the required angle, the first protrusion and the second protrusion cooperate with each other, so that the first protrusion abuts against the second protrusion in the rotation direction of the cover body's opening. The abutting resistance of the second protrusion prevents the connecting pivot from rotating in the same rotation direction, forming a primary limiting structure that restricts the cover body from continuing to rotate and opening in the open state, preventing the cover body from automatically springing open and rotating beyond the limit, and also offsetting the pushing force of the plug, so that the cover body opens stably and is fixed after opening. This prevents the protective cover assembly from being deformed by impact or broken from the socket housing, reduces the failure rate of the protective cover assembly, enhances the closing and protective effect of the protective cover assembly, and improves the reliability of the charging socket.

[0010] Preferably, in the protective cover assembly of this utility model, the connecting pivot is provided with a radially outwardly protruding third protrusion; the first fixing seat is provided with a fourth protrusion perpendicular to the cover surface and protruding toward the connecting pivot; the fourth protrusion and the third protrusion can be contacted and connected, thereby preventing the cover body from opening too far.

[0011] As a preferred embodiment of this utility model, under the action of large or frequent impact forces, if the limiting structure of the first and second protrusions fails due to deformation, then by providing a third and fourth protrusion, when the cover body is opened and rotated beyond its limit, the fourth and third protrusions can contact each other, generating a frictional force parallel to the contact surface of the third and fourth protrusions. The direction of the frictional force is opposite to the rotation trend of the cover body, thereby generating a damping force on the cover body, thus preventing the cover body from opening beyond its limit, and further offsetting part of the impact force, thereby reducing the possibility of the protective cover assembly being deformed or broken due to opening beyond its limit under impact force, and improving the protective reliability of the charging socket protective cover assembly.

[0012] Preferably, in the protective cover assembly of this utility model, the third protrusion is located at an angle of 170° to 180° with the cover body.

[0013] As a preferred embodiment of this utility model, when the cover body is opened and rotated to 90° to 100°, the angle between it and the cover mating surface is 90° to 100°. Within this angle range, the cover body bears a larger component of the impact force and is more easily deformed or broken by impact. By setting the third protrusion and the cover body at an angle of 170° to 180°, a damping force can be generated on the cover body when it is opened and rotated to 90° to 100°. Furthermore, the fourth protrusion is perpendicular to the cover mating surface and protrudes towards the connecting rotating post. As the cover body drives the connecting rotating post to rotate in the opening direction, the gap between the fourth protrusion and the third protrusion gradually decreases, the friction increases, and the damping force against the cover body opening beyond its limit increases. This results in stronger impact resistance within the 90° to 100° range and further improves the protective reliability of the protective cover assembly.

[0014] Preferably, in the protective cover assembly of this utility model, the first protrusion is located at an angle of 90° to 100° with the cover body.

[0015] As a preferred embodiment of this utility model, when the cover body is opened and rotated to 90° to 100°, the angle between the cover body and the mating surface is 90° to 100°. Within this angle range, the cover body bears a larger component of the impact force and is more easily deformed or broken by impact. By setting the position of the first protrusion to be at an angle of 90° to 100° with the cover body, which is the maximum angle range for the cover body to rotate open, the impact resistance to the cover body automatically opening and rotating beyond the limit can be improved, further reducing the probability of the protective cover assembly being deformed by impact or breaking from the socket housing, and improving the reliability of use.

[0016] Preferably, the protective cover assembly of this utility model includes at least two cover bodies; each cover body is provided with the connecting pivot and a first torsion spring; the two cover bodies are coaxially connected to the first pin through the two connecting pivots; one cover body abuts against the back of the other cover body in the closing direction, so that it can close synchronously with the other cover body, or be driven by the other cover body to open synchronously.

[0017] As a preferred embodiment of this utility model, by providing at least two cover bodies, the two different plug ends of the vehicle charging socket are protected respectively. The edge of one cover body abuts against the back of the other cover body in the closing direction. When one cover body is opened, it will not push against the other cover body in the opening direction, thus not affecting the closed state of the other cover body. When one cover body is closed, the abutting force in the closing direction pushes the other cover body to close simultaneously. On the one hand, closing one cover body can simultaneously close two cover bodies, or opening another cover body can simultaneously open two cover bodies, making the closing or opening operation more convenient. On the other hand, in conjunction with the coaxial connection to the first pin, the two cover bodies are closed or opened as a whole, enhancing the stability of rotation, further reducing the possibility of displacement or deformation, and improving reliability.

[0018] To achieve the objective of this utility model, another solution is disclosed:

[0019] A socket housing for an automotive charging socket includes a housing body, a locking assembly, and the protective cover assembly; a first fixing base is fixed to the housing body;

[0020] The locking assembly includes: a second fixing seat, a latching member, and a second pin; the second fixing seat is fixed to the shell body; the latching member is provided with an L-shaped latching groove; the L-shaped latching groove is for the cover body to be inserted into when closed; the pressing surface of the L-shaped latching groove can abut against the cover body in the direction of opening of the cover body; the pressing surface is an inclined surface inclined towards the cover body; the second pin is axially connected to the latching member and its two ends are fixed to the second fixing seat.

[0021] The socket housing of this utility model, by providing the protective cover assembly, can prevent the cover body from automatically opening and rotating beyond its limit, thereby preventing the protective cover assembly from being deformed by impact or breaking from the socket housing, reducing the failure rate of the protective cover assembly, and enhancing the closing protection effect of the protective cover assembly; furthermore, by providing a latching member and an L-shaped latching groove, the cover body can be inserted into the L-shaped latching groove in the closed state, and the pressing surface of the L-shaped latching groove can abut against the cover body in the direction of opening, thereby pressing and fastening the closed cover body, enhancing the closing protection effect of the protective cover assembly; when it is necessary to open the cover body, the latching member... The component can rotate relative to the second fixed seat via the second pin, thereby releasing the pressing and fastening action on the main body and realizing the opening of the cover body; the pressing surface is set as an inclined surface facing the cover body, so that during the process of releasing the pressing and fastening action on the main body, the pressing force of the pressing surface on the cover body gradually decreases, and a component force is generated in the direction of relative movement, thereby increasing the friction between the pressing surface and the cover body, which has a buffering effect on the opening of the cover body, thereby reducing the impact force of the cover body due to rapid opening, making the cover body open stably, avoiding the protective cover assembly from being deformed by impact or broken from the socket housing, and improving the reliability of the charging socket.

[0022] Preferably, in the socket housing for vehicle charging sockets of the present invention, the locking assembly further includes: a second torsion spring; the second torsion spring shaft is connected to the abutment, and the two second connectors of the second torsion spring abut against the abutment and the second fixing seat respectively, thereby being able to elastically twist relative to the second fixing seat.

[0023] As a preferred embodiment of this utility model, by setting the locking assembly to include a second torsion spring, the fastening component can be improved into a component that can elastically rotate to fasten or release the fastening, which can buffer the locking and unlocking forces, further reduce the possibility of impact damage to the protective cover assembly caused by the rapid release of the lock, and buffer the impulse between the lock and the cover body, reduce the wear rate of the locking assembly, and extend its service life.

[0024] Preferably, in the socket housing for vehicle charging sockets of this utility model, the abutment member is provided with a fifth protrusion that bulges outward radially along the second pin shaft; the second fixing seat is provided with a first limiting baffle and a second limiting baffle; the first limiting baffle and the second limiting baffle are located on both sides of the fifth protrusion in the radial direction, thereby restricting the abutment member from rotating beyond the limit.

[0025] As the socket housing of this utility model, by setting a fifth protrusion, and cooperating with setting a first limiting baffle and a second limiting baffle, an accommodating cavity is formed between the first limiting baffle and the second limiting baffle. During the rotation of the fastener around the second pin, the fifth protrusion can rotate between the first limiting baffle and the second limiting baffle along with the fastener, preventing the fastener from rotating beyond the limit around the second pin, protecting the safety of the latch, and further improving the reliability of this utility model.

[0026] Preferably, in the socket housing for vehicle charging sockets of this utility model, the first fixing seat and / or the second fixing seat are integrally formed and connected to the housing body.

[0027] As a preferred embodiment of this utility model, the first fixing seat and the second fixing seat can be integrally formed and connected to the shell body, which can further enhance the stability of the position positioning of the first fixing seat and the second fixing seat, thereby reducing the probability of the first pin and the second pin being deflected or offset, improving the matching of the protective cover assembly and the locking assembly, enhancing the stability and firmness of the cover, and further improving the safety and stability of the socket.

[0028] Preferably, in the socket housing for vehicle charging sockets of the present invention, the first pin and the second pin are axially parallel to each other, and the first pin and the second pin are arranged in a mirror-symmetrical manner with respect to a plane perpendicular to the mating surface.

[0029] As a preferred embodiment of this utility model, by having the first pin and the second pin axially parallel to each other, and the first pin and the second pin arranged in a mirror-symmetrical arrangement perpendicular to the cover surface, the rotation of the cover body to close or open, and the rotation of the latch to engage or disengage, can be kept as straight as possible, avoiding excessive force in other directions that could cause the cover body to shift or deform, thereby further enhancing the protective performance of the protective cover assembly and improving the reliability of the vehicle charging socket.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0031] 1. The protective cover assembly, through the setting of the first protrusion and the second protrusion, forms a primary limiting structure, which limits the opening of the cover body in the open state to the limit, prevents the cover body from automatically popping open and rotating beyond the limit, and also counteracts the pushing force of the plug and unplug plug, so that the cover body opens stably and is limited and fixed after opening, thereby preventing the protective cover assembly from being deformed by impact or broken from the socket housing, reducing the failure rate of the protective cover assembly, enhancing the closing protection effect of the protective cover assembly, and improving the reliability of the charging socket.

[0032] 2. The socket housing for the vehicle charging socket integrates the protective cover assembly and the locking assembly. By setting a stop and a second pin, the cover body can be pressed and locked together, enhancing the protective effect of the cover assembly. Furthermore, the L-shaped locking groove of the stop has a buffering effect on the opening of the cover body, thereby reducing the impact force of the cover body opening rapidly, making the cover body open stably, avoiding the protective cover assembly from being deformed by impact or breaking from the socket housing, and improving the reliability of the charging socket.

Detailed Implementation

[0040] The present invention will now be described in detail with reference to the accompanying drawings.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0042] Example 1:

[0043] like Figures 1 to 4 As shown, this embodiment discloses a protective cover assembly 1, including: a cover body 11, a first torsion spring 12, a first pin 13, and a first fixing seat 14; the cover body 11 is provided with a connecting rotating post 15 at one end for connecting the first fixing seat 14; the first torsion spring 12 is axially connected to the connecting rotating post 15, and the two first connecting heads 121 of the first torsion spring 12 respectively abut against the connecting rotating post 15 and the first fixing seat 14, thereby being able to elastically twist relative to the first fixing seat 14;

[0044] The first pin 13 is coaxially connected to the first torsion spring 12 and the connecting column 15, and both ends are fixed to the first fixing seat 14; the first fixing seat 14 can fix the socket housing.

[0045] The outer wall of the connecting rotating column 15 is provided with a first protrusion 151 that protrudes radially outward; the first fixing seat 14 is provided with a second protrusion 141 that protrudes radially inward towards the connecting rotating column 15; the first protrusion 151 can abut against the second protrusion 141 in the rotation direction of the opening of the cover body 11, thereby limiting the opening state of the cover body 11.

[0046] It should be noted that the reference Figure 1 As shown, the connecting pivot 15 is understood to be connected to the side wall and the cover body 11 or integrally formed, with an internal cavity to accommodate the first pin 13, and an internal axial through hole for the first pin 13 to pass through, so as to realize the coaxial connection of the first pin 13 to the first torsion spring 12 and the connecting pivot 15.

[0047] In this embodiment, the elastic torsion is understood as follows: since the two first connectors 121 of the first torsion spring 12 abut against the connecting rotating post 15 and the first fixed seat 14 respectively, the connecting rotating post 15 is driven to rotate during the process of closing the cover body 11, thereby generating an elastic torsion force on the first torsion spring 12, so that the first torsion spring 12 elastically torsional compression generates elastic potential energy for the cover body 11 to automatically spring open when it needs to be opened.

[0048] It should be noted that the rotation direction is understood as the tangent direction of the multiple concentric circular trajectories of the opening rotation of the cover body 11, for reference. Figure 3For example, when the connecting column 15 and the cover body 11 are opened synchronously and rotated counterclockwise, the tangent direction of the trajectory of the first protrusion 151 following the counterclockwise rotation is the rotation direction, so that the first protrusion 151 can abut against the second protrusion 141 in the tangent direction of the rotation trajectory of the first protrusion 151. The first protrusion 151 is stopped by the second protrusion 141 along the tangent direction due to the abutment force, thereby limiting the open cover body 11.

[0049] For details, please refer to Figure 3 and Figure 5 As shown, the connecting pivot 15 is provided with a radially outward protruding third protrusion 152; the first fixing seat 14 is provided with a fourth protrusion 142 that is perpendicular to the cover surface and protrudes toward the connecting pivot 15; the fourth protrusion 142 and the third protrusion 152 can contact each other, thereby preventing the cover body 11 from opening too far.

[0050] The positions of the first protrusion 151, the second protrusion 141, the third protrusion 152, and the fourth protrusion 142 of the protective cover assembly 1 of this utility model can be set according to the actual product design requirements to adjust the opening angle range of the cover body 11, which can be achieved based on the actual situation; specifically, refer to Figure 1 and Figure 3 As shown, the third protrusion 152 is located at an angle of 170° to 180° with the cover body 11; the first protrusion 151 is located at an angle of 90° to 100° with the cover body 11.

[0051] For details, please refer to Figure 1 As shown, the cover body 11 includes at least two; each cover body 11 is provided with a connecting pivot 15 and a first torsion spring 12; the two cover bodies 11 are coaxially connected to the first pin 13 through the two connecting pivots 15 respectively; one cover body 11 abuts against the back of the other cover body 11 in the closing direction, so that it can close synchronously with the other cover body 11, or be driven by the other cover body 11 to open synchronously.

[0052] In this embodiment, the radial direction is understood as the radial direction relative to the first pin 13; the covering surface is understood as the plane on the outer wall of the plug end of the socket housing that the cover body 11 covers, for example, referring to Figure 5 As shown, the closing surface is a horizontal plane; the back side of the cover body 11 is understood as the opposite surface of the cover body 11 used for closing, for example... Figure 1 The image shown shows the back side, with the left side closest to the right. Figure 5 The top of the image shows the back side.

[0053] It should be noted that the socket housing described in this embodiment can be a conventional socket housing for vehicle charging sockets. Depending on the actual design of the vehicle charging socket, the first fixing seat 14 of this utility model can be fixedly connected to a conventional socket housing, or the socket housing described in Embodiment 2 of this utility model can be used for installation and use.

[0054] Example 2:

[0055] refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, based on Embodiment 1, this embodiment provides a socket housing for a vehicle charging socket, including a housing body 2, a locking assembly 3, and a protective cover assembly 1 as described in Embodiment 1; a first fixing seat 14 is fixed to the housing body 2;

[0056] The locking assembly 3 includes: a second fixing seat 31, a latching member 32, and a second pin 33; the second fixing seat 31 is fixed to the shell body 2; the latching member 32 is provided with an L-shaped latching groove 321; the L-shaped latching groove 321 is for the cover body 11 to be inserted into when the cover is closed; the pressing surface 3211 of the L-shaped latching groove 321 can abut against the cover body 11 in the direction of opening the cover body 11; the pressing surface 3211 is an inclined surface that is inclined towards the cover body 11; the second pin 33 is axially connected to the latching member 32 and its two ends are fixed to the second fixing seat 31.

[0057] In this embodiment, reference Figure 6 As shown, specifically, the locking assembly 3 further includes: a second torsion spring 34; the second torsion spring 34 is shaft-connected to the abutment 32, and the two second connectors 341 of the second torsion spring 34 abut against the abutment 32 and the second fixing seat 31 respectively, thereby being able to elastically twist relative to the second fixing seat 31.

[0058] In this embodiment, the elastic torsion is understood as follows: since the two second connectors 341 of the second torsion spring 34 abut against the latching member 32 and the second fixing seat 31 respectively, during the process of using the locking assembly 3 to push the latching member 32 to lock the cover body 11, the latching member 32 rotates around the second pin 33 as the axis, thereby generating an elastic torsion force on the second torsion spring 34. This causes the second torsion spring 34 to elastically compress and generate elastic potential energy, which allows the latching member 32 to automatically rotate back to its original position after the cover body 11 is released from the latching action of the latching member 32. The latching member 32 is understood as a rigid component that can abut against the cover body 11, for example... Figure 1 or Figure 5 The handle latch shown.

[0060] For details, please refer to Figure 1 As shown, the first fixing seat 14 and / or the second fixing seat 31 are integrally formed and connected to the shell body 2. It should be noted that the integral forming connection is understood to mean that the first fixing seat 14, the second fixing seat 31 and the shell body can be connected through a conventional integral forming process, such as injection molding. In this utility model, the socket shell is provided with a plug-in end protective wall 21 to meet the protection of the plug-in connection end. The cover body 11 covers the plug-in end protective wall 21 to achieve protection of the plug-in end.

[0061] For details, please refer to Figure 1 As shown, the first pin 13 and the second pin 33 are axially parallel to each other, and the first pin 13 and the second pin 33 are arranged in a mirror-symmetrical manner with respect to a plane perpendicular to the cover surface. The cover surface described in this embodiment can be understood as the cover surface described in Embodiment 1.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
