[0039] When the charging gun is idle, it is placed on the empty seat of the charging pile, which plays the role of fixing the charger gun and preventing the charging gun from falling. The existing empty seat uses a lever-type locking hook. One end of the locking hook is stuck in the hole reserved on the gun head of the charging gun to achieve the locking purpose, and the other end of the locking hook is connected to a button for easy pressing. In the process of using this structure of the empty seat, one hand needs to press the button, and the other hand needs to hold the charging gun to complete the plugging and unplugging operation, which requires the cooperation of both hands and the operation convenience is not good.

[0040] In view of this, the embodiment of the present invention provides an empty seat 100 and a charging pile. By using the cooperation of the housing 10, the pressure cover 20, the lock core 30 and the elastic member 40 of the empty seat 100, when locking, the elastic member 40 pushes the lock core 30 to extend out of the lock hole 102 so that the lock core 30 locks the gun head of the charging gun; when unlocking, the gun head of the charging gun pushes the lock core 30 into the lock hole 102 so that the gun head of the charging gun is unlocked from the lock core 30. In this way, the plugging and unplugging operation of the charging gun can be completed with one hand, improving the user experience.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the drawings.

[0042] As Figure 1-7 shown, an empty seat 100 proposed by the embodiment of the present invention includes a housing 10, a pressure cover 20, a lock core 30 and an elastic member 40; the housing 10 is provided with a plugging cavity 101 and a lock hole 102 communicating with the plugging cavity 101; the pressure cover 20 covers the lock hole 102, and the pressure cover 20 and the housing 10 enclose an assembly cavity 201; the lock core 30 is arranged in the assembly cavity 201, and one end of the lock core 30 away from the pressure cover 20 has a locking portion 301, and the locking portion 301 extends out of the lock hole 102; an elastic member 40, the elastic member 40 is arranged between the pressure cover 20 and the lock core 30; wherein, when locking, the elastic member 40 pushes the lock core 30 to extend out of the lock hole 102 so that the lock core 30 locks the gun head of the charging gun; when unlocking, the gun head of the charging gun pushes the lock core 30 into the lock hole 102 so that the gun head of the charging gun is unlocked from the lock core 30.

[0043] In the technical solution adopted in this embodiment, there is often an empty seat 100 on the charging pile. When the charging gun is not in use, the charging gun can be fixed on the empty seat 100, which can fix the charging gun, prevent the charging gun from falling, and at the same time make the whole charging pile more tidy and beautiful. The housing 10 of the empty seat 100 is provided with a plugging cavity 101. When the charging gun is not in use, the gun head of the charging gun is inserted into the plugging cavity 101. The housing 10 is also provided with a lock hole 102. The plugging cavity 101 communicates with the lock hole 102. A gland 20 is covered on the lock hole 102. The gland 20 and the housing 10 enclose an assembly cavity 201. A lock core 30 is arranged in the assembly cavity 201. One end of the lock core 30 away from the gland 20 has a locking part 301. The locking part 301 extends out of the lock hole 102. An elastic member 40 is also arranged between the gland 20 and the lock core 30. When the charging gun is not inserted into the plugging cavity 101, the lock core 30 keeps the state that the locking part 301 extends out of the lock hole 102 under the action of the elastic member 40. When the gun head of the charging gun is inserted into the plugging cavity 101, the gun head of the charging gun squeezes the locking part 301, so that the whole lock core 30 moves towards the inside of the assembly cavity 201, and the elastic member 40 is compressed. As the gun head of the charging gun is inserted to the bottom of the plugging cavity 101, at this time, the groove on the gun head of the charging gun is opposite to the lock hole 102. The elastic member 40 releases the elastic potential energy. The elastic member 40 pushes the lock core 30 to extend out of the lock hole 102. The lock core 30 moves in the direction away from the assembly cavity 201, so that the locking part 301 extends out of the lock hole 102. The locking part 301 and the groove inside the gun head of the charging gun are clamped internally, so as to lock the gun head of the charging gun by the lock core 30, thereby realizing the locking of the gun head of the charging gun. When unlocking, the user pulls the charging gun outwards. At this time, because the force exerted by the user pulling outwards is relatively large, the groove wall of the groove on the gun head of the charging gun and the outer shell of the gun head of the charging gun squeeze the lock core 30, so that the lock core 30 moves towards the inside of the assembly cavity 201 and enters the lock hole 102. The elastic member 40 is compressed. Continue to pull the charging gun outwards until the gun head of the charging gun and the lock core 30 are completely separated, thereby realizing the unlocking of the gun head of the charging gun and the lock core 30. At this time, because there is no extrusion of the outer shell of the gun head of the charging gun, the elastic potential energy of the elastic member 40 is released. The lock core 30 moves in the direction away from the assembly cavity 201, so that the locking part 301 extends out of the lock hole 102 and maintains this state until the gun head of the charging gun is inserted into the plugging cavity 101 next time.

[0044] It can be understood that through the cooperation of the housing 10, the gland 20, the lock core 30 and the elastic member 40, the traditional empty seat with a button is replaced, the hands are freed, and the user can complete the action of plugging and unplugging the charging gun from the empty seat 100 with one hand, improving the user experience. It can be understood that the elastic member 40 can be an element such as a spring piece or a spring that can store and release elastic potential energy. Preferably, the elastic member 40 is a spring.

[0045] Furthermore, in the technical solution adopted in the present invention, as Figure 1-2As shown, the number of keyholes 102 is two, and the two keyholes 102 are oppositely arranged on both sides of the housing 10.

[0046] It can be understood that in traditional empty seats, a single-point locking hook is used to fix the charging gun head. At this time, under the self-weight of the cable, the charging gun head is prone to offset when cooperating with the empty seat 100. The position where the locking hook and the charging gun head cooperate is under long-term single-point forced stress, greatly reducing the service life of the charging gun head and the empty seat. In order to improve the connection stability between the charging gun head and the empty seat 100, in one embodiment of the present invention, the number of keyholes 102 on the empty seat 100 is two, and the two keyholes 102 are oppositely arranged on both sides of the housing 10. It can be understood that a gland 20, a lock core 30, and an elastic member 40 are provided on each keyhole 102. Preferably, the two keyholes 102 are symmetrically arranged on both sides of the empty seat 100. It can be understood that by symmetrically arranging the keyholes 102 on both sides of the empty seat 100, the force on the charging gun head is more uniform, preventing the offset of the gun head during cooperation under self-weight, and effectively improving the service life of the empty seat 100.

[0047] Furthermore, in the technical solution adopted by the present invention, as Figure 1 , 3 -5 shows, the gland 20 includes a bottom wall 208 and a side wall 202 perpendicular to the bottom wall 208, and the bottom wall 208 and the side wall 202 enclose a receiving groove 203.

[0048] It can be understood that the gland 20 includes a bottom wall 208 and a side wall 202 perpendicular to the bottom wall 208, and the bottom wall 208 and the side wall 202 enclose a receiving groove 203. When the gland 20 is covered on the keyhole 102, the housing 10 presses on the notch of the receiving groove 203, thereby forming an assembly cavity 201.

[0049] Furthermore, in the technical solution adopted by the present invention, as Figure 1 , 3 -4, 6-7 show, a limiting portion 302 is further provided on one side of the locking portion 301 facing the bottom wall 208, and the limiting portion 302 extends radially along the lock core 30 to cover the keyhole 102.

[0050] It can be understood that a limiting portion 302 is further provided on one side of the locking portion 301 facing the bottom wall 208, and the limiting portion 302 extends radially along the lock core 30 to cover the keyhole 102. When the charging gun head is not inserted into the insertion cavity 101, at this time, the locking portion 301 extends out of the keyhole 102 under the action of the elastic member 40, and the limiting portion 302 covers the keyhole 102, preventing the lock core 30 from falling off from the keyhole 102 and the insertion cavity 101, and keeping the lock core 30 always in the assembly cavity 201.

[0051] Furthermore, in the technical solution adopted by the present invention, asFigure 1 , 3 As shown in FIG. -5, a guiding shaft 204 protrudes from the bottom wall 208 towards the keyhole 102. A guiding hole 303 corresponding to the guiding shaft 204 is provided on the limiting part 302 facing the bottom wall 208, and the front end of the guiding shaft 204 extends into the guiding hole 303; the diameter of the guiding shaft 204 is smaller than the aperture of the guiding hole 303.

[0052] It can be understood that in order to ensure that the lock core 30 always moves horizontally along the axial direction of the lock core 30 during the movement in the assembly cavity 201, a guiding shaft 204 protrudes from the bottom wall 208 of the gland 20 towards the keyhole 102. A guiding hole 303 corresponding to the guiding shaft 204 is provided on the limiting part 302 facing the bottom wall 208, and the front end of the guiding shaft 204 extends into the guiding hole 303; the diameter of the guiding shaft 204 is smaller than the aperture of the guiding hole 303. Such a setting enables the lock core 30 to always move along the axial direction of the lock core 30 under the cooperation of the guiding shaft 204 and the guiding hole 303. It can be understood that the axis of the guiding shaft 204 coincides with the axis of the keyhole 102. Preferably, the axis of the guiding shaft 204, the axis of the keyhole 102 and the axis of the lock core 30 coincide.

[0053] Furthermore, in the technical solution adopted by the present invention, as Figure 1-7 shown, a first limiting groove 304 is further provided on one side of the limiting part 302 facing the bottom wall 208. The first limiting groove 304 is arranged around the guiding hole 303. A second limiting groove 205 is provided on one side of the bottom wall 208 facing the lock core 30. The second limiting groove 205 is arranged around the guiding shaft 204. One end of the elastic member 40 is fixed in the first limiting groove 304, and the other end of the elastic member 40 is fixed in the second limiting groove 205.

[0054] It can be understood that in order to prevent displacement among the lock core 30, the elastic member 40 and the gland 20, a first limiting groove 304 is further provided on one side of the limiting part 302 facing the bottom wall 208. The first limiting groove 304 is arranged around the guiding hole 303. A second limiting groove 205 is provided on one side of the bottom wall 208 facing the lock core 30. The second limiting groove 205 is arranged around the guiding shaft 204. One end of the elastic member 40 is fixed in the first limiting groove 304, and the other end of the elastic member 40 is fixed in the second limiting groove 205. By fixing the two ends of the elastic member 40 in the first limiting groove 304 and the second limiting groove 205 respectively, displacement among the elastic member 40, the lock core 30 and the gland 20 is prevented, and the stability of the entire locking and unlocking process of the empty seat 100 is improved.

[0055] Furthermore, in the technical solution adopted by the present invention, as Figure 1-7As shown, the limiting part 302 is convexly provided with limiting ears 305 on opposite sides, and the side wall 202 is also provided with a limiting groove 206 corresponding to the limiting ears 305. The limiting ears 305 and the limiting groove 206 are slidably connected.

[0056] It can be understood that by providing the limiting ears 305 on the limiting part 302 and the limiting groove 206 on the side wall 202 of the gland 20, when the lock core 30 moves, the limiting ears 305 always slide in the limiting groove 206, further improving the stability of the movement of the lock core 30.

[0057] Furthermore, in the technical solution adopted by the present utility model, as Figure 1-7 shown, the side wall 202 is also provided with a fastening hole 207. The fastening hole 207 is parallel to the guiding shaft 204. The housing 10 is also provided with a fastening post 103 corresponding to the fastening hole 207. The fastening post 103 is inserted into the fastening hole 207, and a fastener 50 is inserted into the fastening hole 207 to be fixedly connected to the fastening post 103.

[0058] It can be understood that during the production of the empty seat 100, the gland 20 can be integrally formed with the housing 10 or designed to be a split form. When the gland 20 and the housing 10 are in a split form, in order to improve the connection stability between the gland 20 and the housing 10, the side wall 202 is also provided with a fastening hole 207. The fastening hole 207 is parallel to the guiding shaft 204. The housing 10 is also provided with a fastening post 103 corresponding to the fastening hole 207. The fastening post 103 is inserted into the fastening hole 207, and a fastener 50 is inserted into the fastening hole 207 to be fixedly connected to the fastening post 103. Through the cooperation among the fastener 50, the fastening hole 207, and the fastening post 103, the gland 20 and the housing 10 are fixed together.

[0059] Furthermore, in the technical solution adopted by the present utility model, as Figure 1 、 3 shown in FIGS. 4 and 6 - 7, one side of the locking part 301 facing the insertion cavity 101 is provided with a locking surface 3011. The locking surface 3011 includes a first connection surface 3012 and a second connection surface 3013. The first connection surface 3012 and the second connection surface 3013 are located at both ends of the locking surface 3011 close to the hole wall of the lock hole 102. When the charging gun head is inserted into the insertion cavity 101, it presses the first connection surface 3012, so that the locking surface 3011 moves in a direction away from the insertion cavity 101. When the charging gun head is pulled out of the insertion cavity 101, it presses the second connection surface 3013, so that the locking surface 3011 moves in a direction away from the insertion cavity 101.

[0060] It can be understood that as Figure 4As shown, the locking surface 3011 is located on the side of the locking portion 301 facing the insertion cavity 101. The locking surface 3011 includes a first connecting surface 3012 and a second connecting surface 3013, and the first connecting surface 3012 and the second connecting surface 3013 are located at both ends of the locking surface 3011 close to the wall of the locking hole 102. When the charging gun head is inserted into the insertion cavity 101, the charging gun head will first contact the first connecting surface 3012 and press the first connecting surface 3012, so that the locking surface 3011 moves in a direction away from the insertion cavity 101. When the charging gun head is locked with the lock core 30, under the action of the elastic member 40, the locking surface 3011 extends out of the locking hole 102, and the lock core 30 is clamped at the groove of the charging gun head housing to realize the locking of the charging gun head. When the charging gun head is pulled out of the insertion cavity 101, under the action of an external force, the notch of the groove of the charging gun head housing will first contact the second connecting surface 3013 and press the second connecting surface 3013, so that the locking surface 3011 moves in a direction away from the insertion cavity 101.

[0061] Further, in the technical solution adopted by the present utility model, as Figure 4 shown, the locking surface 3011 further includes a transition surface 3014, and the transition surface 3014 is located between the first connecting surface 3012 and the second connecting surface 3013.

[0062] It can be understood that when the charging gun head is inserted into the insertion cavity 101, the charging gun head presses the first connecting surface 3012, so that the locking surface 3011 moves in a direction away from the insertion cavity 101. As the charging gun head is pushed forward, the charging gun head will press the transition surface 3014, causing the locking surface 3011 to continue to move in a direction away from the insertion cavity 101. When the charging gun head continues to be pushed forward, the transition surface 3014 will abut against the outer wall of the charging gun head until the lock core 30 is clamped at the groove of the charging gun head housing, thereby realizing the locking of the charging gun head. When the charging gun head is pulled out of the insertion cavity 101, the notch of the groove of the charging gun head housing will first contact the second connecting surface 3013 and press the second connecting surface 3013, so that the locking surface 3011 moves in a direction away from the insertion cavity 101. As the charging gun head is pulled out, the notch of the groove of the charging gun head housing will press the transition surface 3014, causing the locking surface 3011 to continue to move in a direction away from the insertion cavity 101. When the charging gun head continues to be pulled out, the transition surface 3014 will abut against the outer wall of the charging gun head until the lock core 30 is separated from the outer wall of the charging gun head.

[0063] Further, in the technical solution adopted by the present utility model, the first connecting surface 3012 and the second connecting surface 3013 are arc-shaped surfaces.

[0064] It can be understood that, for the smooth advancement and extraction of the charging gun head and the locking surface 3011, the first connecting surface 3012 and the second connecting surface 3013 are arc-shaped surfaces. With such a setting, after the charging gun head is inserted into the insertion cavity 101, the charging gun head can smoothly slide from the first connecting surface 3012 to the transition surface 3014, facilitating the snap connection of the lock core 30 at the groove of the charging gun head housing. When the charging gun head is pulled out of the insertion cavity 101, the notch of the groove of the charging gun head housing can smoothly slide from the second connecting surface 3013 to the transition surface 3014, making it easier for the charging gun head to be inserted and pulled out.

[0065] Furthermore, in the technical solution adopted by the present utility model, the locking surface 3011 is an arc-shaped surface.

[0066] It can be understood that, as Figure 7 shown, one side of the locking portion 301 facing the lock hole 102 is provided with a locking surface 3011. As Figure 3 、 4 、7 shows, the locking surface 3011 is an arc-shaped surface. By designing the locking surface 3011 into an arc shape, during the insertion process of the charging gun head, the insertion force can be decomposed into a force that pushes the lock core 30 towards the assembly cavity 201 and a resistance that hinders the insertion of the gun head. The force in the moving direction of the lock core 30 pushes the lock core 30 into the assembly cavity 201. When the charging gun head is fully inserted, the elastic member 40 pushes the lock core 30 to protrude from the lock hole 102 and snap into the groove of the charging gun head housing, facilitating the insertion and locking of the charging gun head. During the process of pulling out the charging gun head, similarly, the pulling-out force can be decomposed into a force in the moving direction of the lock core 30 and a resistance that hinders the pulling out of the gun head. By designing the cross-section of the locking surface 3011 as an arc shape, it is convenient for the user to move the lock core 30 into the corresponding assembly cavity 201 under the action of the charging gun head housing during the process of inserting or pulling out the charging gun, facilitating plugging and unplugging. It can be understood that when the locking surface 3011 is an arc-shaped surface, the first connecting surface 3012, the second connecting surface 3013, and the transition surface 3014 are all arc-shaped surfaces, and the locking surface 3011 formed by the first connecting surface 3012, the second connecting surface 3013, and the transition surface 3014 together is also an arc-shaped surface.

[0067] The embodiment of the present utility model also proposes a charging pile, which includes a seat body and the above-mentioned empty seat 100, and the empty seat 100 is arranged on the seat body. Specifically, for the specific structure of the empty seat 100, refer to the above embodiment. Since the empty seat 100 adopts all the technical solutions of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, and will not be elaborated here one by one.

[0068] The above are only alternative embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
