[0030] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.
[0031] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0032] like Figures 1 to 4 As shown, at least one embodiment provides a charging dock with a locking rod heating function, including: a housing 1, which is used to install a connector 2, and a through hole 11 is provided on the housing 1; an electronic lock 3, which is disposed on the side wall of the housing 1, and includes: a locking rod 31, the outer end of the locking rod 31 being located in the through hole 11; wherein, a heating module is provided at the locking rod 31.
[0033] Specifically, when connector 2 is inserted into the charging head, the locking lever 31 of electronic lock 3 will extend outward to lock the charging head.
[0034] In this embodiment, a heating module is provided at the locking rod 31 to melt the ice that is frozen to the locking rod 31 when it is frozen, thereby loosening the locking rod 31 and the ice, which makes it easier for the locking rod 31 to retract.
[0035] like Figure 1 As shown, in some embodiments, the outer casing 1 includes: a housing 12 and a flange 13; wherein an annular mounting groove 14 is provided on the opposite surface of the housing 12 or the flange 13; the annular mounting groove 14 is located around the perforation 11; the heating module is disposed in the annular mounting groove 14 and surrounds the locking rod 31.
[0036] Specifically, after the heating module is installed in the annular mounting groove 14, it is limited by the connection between the flange 13 and the housing 12.
[0037] In this embodiment, the heating module does not directly contact the locking rod 31. Instead, it heats the housing 1 at the perforation 11 to melt the ice inside the perforation 11, which is highly targeted and has a good heating effect.
[0038] In some embodiments, the heating module is a first aluminothermic plate 41 or a first thin-film heating element; wherein the first aluminothermic plate 41 is disposed in the annular mounting groove 14 and is sleeved on the periphery of the locking rod 31 through the first through hole 411 thereon; the first thin-film heating element is disposed in the annular mounting groove 14 and is wound to form an annular shape.
[0039] In this embodiment, the first aluminum hot plate 41 does not directly contact the locking rod 31, but its heating surface contacts the outer shell 1, and the ice in the perforation 11 is melted by heating the outer shell 1; wherein, the shapes of the first aluminum hot plate 41 and the first thin film heating sheet are adapted to fit the perforation 11 so as to uniformly heat the periphery of the perforation 11.
[0040] In some embodiments, the heating module is powered and controlled separately by the vehicle body, that is, the operation of the heating module is directly controlled by a control button; wherein, the control button can be a physical button or a virtual button.
[0041] like Figure 2 As shown, in some embodiments, the heating module is disposed within the perforation 11 and surrounds the locking rod 31.
[0042] In this embodiment, the heating module is directly installed in the through hole 11, and the size of the through hole 11 is adapted to the heating module; at the same time, the locking rod 31 passes through the heating module when the locking action is performed.
[0043] In some embodiments, the heating module is a high-frequency coil module 42; wherein the high-frequency coil module 42 is disposed in the through hole 11 and is sleeved on the periphery of the locking rod 31 through the second through hole 421 thereon.
[0044] In some embodiments, the locking bar 31 is made of metal.
[0045] In this embodiment, since the locking rod 31 passes through the second through hole 421 of the high-frequency coil module 42, the ice is located inside the second through hole 421. The high-frequency coil module 42 directly heats the metal locking rod 31, which has extremely high heating efficiency and can melt the frozen ice in a very short time.
[0046] like Figure 3 As shown, in some embodiments, the heating module is disposed inside the electronic lock 3 and surrounds the lock rod 31.
[0047] In this embodiment, the heating module is integrated into the electronic lock 3. If existing vehicles need to implement the heating function of the lock bar 31, they only need to replace the electronic lock 3, without needing to modify the structure of the charging dock.
[0048] In some embodiments, the heating module is a second aluminothermic plate 43 or a second thin-film heating element.
[0049] Specifically, such as Figure 4 As shown, when the second aluminized hot plate 43 is used, the second aluminized hot plate 43 is set inside the electronic lock 3 and is sleeved on the outside of the lock rod 31 through the third through hole 431 on it. At the same time, the second aluminized hot plate 43 is connected to the PCB board inside the electronic lock 3 to realize installation and circuit connection.
[0050] Specifically, when a second thin-film heating element is used, since it is thin-film, the second thin-film heating element needs to be set on a mounting plate or on the inner wall of the electronic lock 3.
[0051] In some embodiments, the heating module is connected to the motor circuit of the electronic lock 3.
[0052] In this embodiment, the heating module is integrated into the electronic lock 3. When unlocking is required, the control module controls the motor circuit of the electronic lock 3 to work (i.e., the motor drives the lock rod 31 to unlock). At this time, although the lock rod 31 is restricted by the ice and cannot retract, the energized motor circuit simultaneously supplies power to the heating module, so that the heating module heats the lock rod 31. If the lock cannot be unlocked in one drive, the number of unlocking attempts can be increased.
[0053] In summary, this charging dock with a locking rod heating function heats the ice at the locking rod 31 by setting a heating module on the locking rod 31, thereby loosening the locking rod 31 and the ice, so that the locking rod 31 can retract. The heating module can be set between the housing 12 and the flange 13 of the outer shell 1 to heat the ice in the perforation 11; the heating module can also be set inside the perforation 11 to directly heat the locking rod 31; the heating module can also be set inside the electronic lock 3 and powered by the motor circuit of the electronic lock 3 to generate heat synchronously when the motor is working.
[0054] In this document, when it is said that the first component is located on the second component, this can mean that the first component can be directly formed on the second component, or that the third component can be inserted between the first component and the second component.
[0055] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present.

Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0062] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0063] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
