Description

Technical Field

[0001] The utility model relates to the technical field of charging guns, and in particular to an anti-collision charging device and charging equipment. Background Art

[0002] With the rapid development of the electric vehicle market, the demand for charging infrastructure is growing. As an integral part of the electric vehicle charging process, the quality and performance of the charging gun directly impact the user's charging experience and vehicle safety. Existing charging guns are prone to collisions and potential falls during charging due to the flow of people or environmental factors. Therefore, charging guns are equipped with a hook structure to secure them to the vehicle being charged.

[0003] However, in actual use, it has been found that after repeated collisions, the pin structure (i.e., the connection mechanism) between the hook structure and the charging gun is prone to cracking. Under long-term fatigue use, these cracks gradually expand, eventually leading to product failure. To address this problem of product failure, existing technologies often use springs between the hook and the charging gun to cushion the impact, but this increases the size of the charging gun, affecting user experience. Summary of the Invention

[0004] The purpose of the utility model is to provide an impact-resistant charging device and a charging apparatus, so as to solve the problem that the pin structure of the existing charging gun is easily broken due to external force.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] In a first aspect, an impact-resistant charging device is provided, comprising: a charging gun body, a locking member, a locking groove, and a shaft member disposed on the charging gun body, the locking member being embedded in the locking groove, the locking member being provided with a pair of symmetrical bearing brackets on two side plates, and a button being disposed on a first end of the locking member;

[0007] Two bearing seats are arranged on both side walls of the locking groove, and the bearing seats extend outward from the side walls to form a reinforcement portion. A fixed support seat is arranged between the two bearing seats, and a channel is arranged through the fixed support seat;

[0008] The shaft is used to pass through the bearing seat, the bearing support and the channel.

[0009] Preferably, a locking groove is provided at the second end of the locking member, and a locking platform is provided at the end edge of the locking groove, and the locking platform is used to engage with the locking groove when the second end falls.

[0010] Preferably, the second end is provided with a guide groove opening downward, and the inner wall of the guide groove gradually slopes inwardly of the groove;

[0011] A guide platform protruding upward in a vertical direction is provided in the locking groove, and an outer wall of the guide platform is inclined outward. The guide platform is used to be inserted into the guide groove when the second end falls.

[0012] Preferably, a plurality of groups of connecting plates are provided on both sides of the fixed support base, and a group of adjacent sides of the connecting plates are respectively connected to the fixed support base and the charging gun body.

[0013] Preferably, a first abutment is provided at the first end and below the button, and a second abutment is provided in the lock groove. The second abutment is used to abut against the first abutment after the first end falls a certain distance in the vertical direction when the button is pressed.

[0014] Preferably, the second end is provided with a convex rib, and the convex rib is used to contact the upper surface of the fixed support seat and support the locking member when the locking member rotates on the shaft.

[0015] Preferably, the second end is provided with a clamping portion for clamping and fixing the charging gun body during charging.

[0016] Preferably, the charging gun body is provided with a handshake portion, and a surface of the handshake portion is provided with a plurality of protrusions for increasing the surface friction of the handshake portion.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The utility model significantly enhances the structural strength of the bearing seat by arranging a reinforcement part on the outside of the bearing seat in the locking groove, preventing the pin shaft hole of the bearing seat from cracking during use, effectively solving the problem that the pin shaft hole of the existing charging gun is prone to cracking, and ensuring the reliability and durability of the charging gun under long-term use conditions.

[0021] By arranging a fixed support seat between the two opposing bearing seats, the contact area between the charging gun body and the shaft is increased, so that when an external impact occurs, the force generated between the locking member and the locking groove through the shaft not only occurs on the bearing seat, but is also transmitted to the charging gun body through the shaft and the fixed support seat, reducing the force on the bearing seat and the bearing bracket, and avoiding the bearing seat and the bearing bracket from being torn or cracked due to force.

Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0034] Example 1

[0035] Please refer to Figure 1-Figure 4 The present invention provides an anti-impact charging device, including a charging gun body 1, a locking member 2, a locking groove 3, and a shaft 4. The locking member 2 is embedded in the locking groove 3. The locking member 2 is provided with a pair of symmetrical bearing brackets 21 on both side plates, and a button 22 is provided on the first end 23 of the locking member 2.

[0036] Two bearing seats 31 are oppositely arranged on the two side walls of the locking groove 3, and the bearing seats 31 extend outward from the side walls to form a reinforcement portion 32. A fixed support seat 5 is arranged between the two bearing seats 31, and a channel 51 is provided through the fixed support seat 5.

[0037] The shaft 4 is used to pass through the bearing seat 31 , the bearing bracket 21 and the channel 51 .

[0038] Specifically, the locking member 2 is embedded in the locking groove 3, and the bearing seat 31 and the bearing bracket 21 are respectively arranged at the middle position of the locking groove 3 and the locking member 2 in the length direction. The shaft 4 passes through the bearing seat 31 and the bearing bracket 21, so that the locking member 2 performs a seesaw motion through the shaft 4, that is, the button 22 set on the upper surface of the first end 23 is pressed, and the first end 23 moves downward into the locking groove 3, and the second end 24 of the locking member 2 away from the first end 23 is tilted upward. When the button 22 is released, the second end 24 falls and the first end 23 moves upward.

[0039] The vertical direction is a direction perpendicular to the upper surface of the locking member 2. The bearing seat 31, the pin shaft hole of the bearing bracket 21 and the channel 51 of the fixed support seat 5 are on the same horizontal line, that is, there is a same center line, so that the shaft 4 can pass through smoothly for connection.

[0040] Preferably, the second end 24 is provided with a clamping portion 26 for clamping and fixing the charging gun body 1 during charging.

[0041] When the charging gun is inserted into the vehicle's charging port, the button 22 is pressed. The second end 24 of the sliding lock member 2 moves upward, away from the charging gun's tip 14, through the shaft 4, bearing bracket 21, and bearing seat 31, tightly engaging the tip 14 with the vehicle's charging port. Releasing the button 22 causes the second end 24 to drop, allowing the engaging portion 26 to engage with the groove structure provided on the charging vehicle, securing the charging gun and the charging vehicle in place and preventing the tip 14 from becoming loose. To remove the charging gun, the button 22 is pressed, causing the second end 24 to move upward, releasing the connection between the charging gun and the vehicle. The tip 14 is then removed, and the button 22 is released.

[0042] When charging is not in progress, the engaging portion 26 engages the front end of the charging gun body 1 to prevent the locking member 2 from removing from the locking groove 3. When the button 22 is pressed, the engaging portion 26 separates from the front end of the charging gun body 1, allowing the second end 24 of the locking member 2 to move upward.

[0043] Bearing brackets 21 extend downward from both side panels of the locking member 2. These bearing brackets 21 support the shaft 4, ensuring that the locking member 2 can seesaw on the shaft 4. A button 22 is also provided on the upper surface of the first end 23 of the locking member 2. The user can press button 22 to control the sliding of the locking member 2, thereby locking and unlocking the charging gun.

[0044] This embodiment significantly enhances the structural strength of the charging gun in the pin shaft hole by providing reinforcement portions 32 on both sides of the locking groove 3 and providing a fixed support seat 5 between the two bearing seats 31, thereby preventing the pin shaft holes of the bearing seat 31 and the bearing bracket 21 from cracking during use, thereby extending the service life of the charging gun.

[0045] The fixed support effectively disperses the forces acting on the pin holes of the bearing seat 31 and the bearing bracket 21, protecting them to a certain extent. Furthermore, when the charging gun body 1 is subjected to impact forces along the length of the locking slot 3, the risk of cracking the gun head 14 due to impact is avoided, improving the safety of the charging gun in complex operating environments.

[0046] In one embodiment, if Figure 3 and Figure 4 As shown, a locking groove 241 is provided at the second end 24 of the locking member 2 , and a locking platform 33 is provided at the end of the locking groove 3 , and the locking platform 33 is used to engage with the locking groove 241 when the second end 24 falls.

[0047] Specifically, the locking groove 241 refers to a recessed area provided on the lower surface of the second end 24 of the locking member 2, and the locking platform 33 refers to an end edge provided on the length direction of the locking groove 3. The locking platform 33 and the locking groove 241 are docked to ensure that the locking member 2 is positioned on the locking groove 3 when not charging.

[0048] In this embodiment, the engaging groove 241 and the engaging platform 33 are provided to ensure that the locking member 2 can be stably maintained in a predetermined position in the locked state, preventing the locking member 2 from moving arbitrarily under uncontrolled conditions, thereby avoiding misoperation or affecting the normal use of the charging gun. In terms of the overall structure, the appearance structure is relatively regular and beautiful.

[0049] When the user needs to insert the charging gun into the vehicle charging port, he only needs to press the button 22, the first end 23 of the locking member 2 falls, and the second end 24 disengages from the engaging platform 33 to complete the unlocking operation; after the charging gun head 14 is inserted, release the button 22, and the engaging portion 26 of the first end 23 is engaged with the electric vehicle to fix the charging gun. After charging is completed, press the button 22, the second end 24 moves up, and the connection between the engaging portion 26 and the electric vehicle is released. Pull out the gun head 14, release the button 22, the second end 24 falls, and the engaging groove 241 engages with the engaging platform 33.

[0050] In one embodiment, if Figure 4 and Figure 5 As shown, the second end 24 is provided with a guide groove 242 opening downward, and the inner wall of the guide groove 242 gradually slopes toward the groove;

[0051] A guide platform 34 protruding upward in the vertical direction is provided in the locking groove 3 , and the outer wall of the guide platform 34 is tilted outward. The guide platform 34 is used to be inserted into the guide groove 242 when the second end 24 falls.

[0052] Specifically, the guide groove 242 is arranged on the lower surface of the locking member 2, with its opening direction facing downward, and the inner wall gradually tilted toward the groove, forming a structure that gradually becomes smaller from the groove mouth to the groove bottom in the vertical direction; the outer wall of the guide platform 34 is tilted outward, and after charging is completed, the locking member 2 is to be embedded in the locking groove 3. The guide groove 242 with the inner wall gradually tilted toward the groove and the guide platform 34 with the outer wall tilted can act as a guide wire to guide the locking member 2 to be correctly embedded in the locking groove 3.

[0053] The guide platform 34 is higher than the height of the locking platform 33 in the vertical direction, that is, the guide platform 34 is higher than the side wall height of the locking groove 3. The guide groove 242 also has a certain depth. During the charging process, after releasing the button 22, the second end 24 falls back a certain distance. After falling, the guide platform 34 can be inserted into the wire groove. When the charging gun is hit by an external impact, it can effectively disperse and absorb the impact force, prevent the locking component 2 from being deflected or damaged, thereby improving the reliability and durability of the charging gun.

[0054] A connecting base 36 is provided below the guide platform 34 for connecting the charging gun body 1 and the guide platform 34 and raising the guide platform 34 so that the second end 24 can be inserted into the guide groove 242 after it falls during charging, thereby avoiding the guide platform 34 from being too large and causing a load, and allowing the guide platform 34 provided above the connecting base 36 to decompose and dissipate the impact force when subjected to external impact without causing the guide platform 34 to break.

[0055] In one embodiment, if Figure 2 and Figure 4 As shown, multiple groups of connecting plates 52 are provided on both sides of the fixed support base 5 , and a group of adjacent sides of the connecting plates 52 are respectively connected to the fixed support base 5 and the charging gun body 1 .

[0056] Specifically, multiple connecting plates 52 are spaced apart on the same side of the fixed support base 5. The fixed support base 5 is integrally connected to the charging gun body 1. The connecting plates 52 support and reinforce the connection between the fixed support base 5 and the charging gun body 1, enhancing the connection strength between the fixed support base 5 and the charging gun body 1 and ensuring that the fixed support base 5 can better perform its supporting and force dispersing functions. This prevents the fixed support base 5 from deforming when subjected to force, thereby improving the overall structural strength and impact resistance of the charging gun.

[0057] In one embodiment, if Figure 3-Figure 5As shown, the first end 23 is provided with a first abutment 231 below the button 22, and a second abutment 35 is provided in the lock groove 3. The second abutment 35 is used to abut against the first abutment 231 after the first end 23 falls a certain distance in the vertical direction when the button 22 is pressed.

[0058] Specifically, when the button 22 is pressed, the first abutting member 231 contacts the second abutting member 35 , thereby limiting the falling distance of the first end 23 of the locking member 2 .

[0059] The purpose of this embodiment is to limit the maximum falling distance of the first end 23 of the locking member 2 by setting the first abutment member 231 and the second abutment member 35, to ensure that when the button 22 is pressed, the first end 23 of the locking member 2 can only fall to a certain position, thereby preventing the locking member 2 from excessive movement causing structural damage or functional failure.

[0060] In one embodiment, if Figure 3 、 Figure 5 and Figure 6 As shown, the second end 24 is provided with a rib 25 , and the rib 25 is used to contact the upper surface of the fixed support seat 5 and support the locking member 2 when the locking member 2 rotates on the shaft 4 .

[0061] Preferably, the ribs 25 are arranged in a staggered manner in the transverse and longitudinal directions, one end of the longitudinal rib 25 is connected to the guide groove 242, and a transverse rib 25 is arranged between the bearings. The two ends of the transverse rib 25 are respectively connected to the two side walls of the locking groove 3. The arrangement of the ribs 25 strengthens the structural strength of the locking groove 3. At the same time, during installation, Figure 6 As shown, the transverse ribs 25 can contact the upper surface of the fixed support seat 5, so that part of the force can act on the ribs 25 to achieve force dispersion.

[0062] In one embodiment, if Figure 1 and Figure 2 As shown, the charging gun body 1 is provided with a gripping portion 11 , and a surface of the gripping portion 11 is provided with a plurality of protrusions 12 for increasing the surface friction of the gripping portion 11 .

[0063] Specifically, a plurality of protrusions 12 are distributed on the surface of the grip portion 11 . The size and shape of the protrusions 12 can be designed according to actual needs, including circular and hemispherical shapes, to provide a good touch and grip feeling.

[0064] The design of the protrusions 12 not only increases the surface friction of the grip portion 11 , making it more stable for the user to hold the charging gun and less likely to slip, but also makes the grip portion 11 more beautiful.

[0065] Preferably, an unlocking mark 13 is provided on the side of the charging gun body 1. When the gun head 14 of the charging gun is correctly inserted into the electric vehicle, the unlocking mark 13 becomes bright to indicate unlocking. After charging is completed, the gun head 14 is pulled out and the unlocking mark 13 becomes dark, indicating that the charging gun is locked and no longer charging. When the gun head 14 is loosened or slipped out by external impact, the gun head 14 can be quickly adjusted through the unlocking mark 13. Example 2
