Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging equipment, in particular to a wireless charging part of a mobile vehicle. Background Art

[0002] Charging piles are commonly used equipment for charging electric vehicles. The current electric vehicle charging equipment is floor-standing or wall-mounted charging piles and portable chargers. Portable chargers generally have low power and slow charging time. Floor-standing and wall-mounted fast charging piles occupy a large amount of bottom space, further causing parking space shortage. Each parking space is equipped with a charging pile, resulting in a large number of charging piles being idle, a huge waste of resources. For this reason, we have proposed a hanging rail charging system (empty rail) to solve the above problems.

[0003] When the above-mentioned hanging rail charging system moves along the track, it is necessary to use a mobile cart to move the charging pile to the designated position. The mobile cart cannot obtain a stable power source when moving. In order to ensure the sustainable operation of the mobile cart, a wireless charging module is proposed to power the cart. The wireless charging module is arranged on the top surface of the cart. During use, the wireless charging module will generate heat, which is difficult to dissipate. In order to maintain the temperature of the power supply environment, a wireless charging part of the mobile cart is proposed to solve the above-mentioned problem. Utility Model Content

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0040] See also Figure 1-5 The utility model discloses a wireless charging unit of a mobile trolley, which is used to power a mobile trolley 1 moving along a hanging rail 01, and includes:

[0041] The mobile vehicle 1 and the charging seat 02 are provided with a first charging part 2 and a second charging part 3 that cooperate with each other;

[0042] The first charging unit 2 and the second charging unit 3 are wireless chargers that cooperate with each other;

[0043] The first charging unit 2 is provided with a heat dissipation component 4;

[0044] The heat dissipation assembly 4 includes air ducts 41 disposed on both sides of the first charging unit 2;

[0045] The first charging part 2 and the second charging part 3 are provided with magnetic suction parts 5 corresponding to the air duct 41. The magnetic suction parts 5 are used to tilt the air duct 41 toward the second charging part 3 when the first charging part 2 and the second charging part 3 are opposite to each other, so that the heat dissipation component 4 dissipates heat from the second charging part 3.

[0046] When the present application is in use, the heat dissipation component 4 arranged on the first charging part 2 in the mobile cart 1 is used to dissipate heat to the first charging part 2 during the charging process. An air duct 41 is also provided. During the charging process, the air duct 41 can be tilted toward the second charging part 3 to dissipate heat to the second charging part 3 simultaneously. After charging is completed, when the two magnetic suction parts 5 are misaligned, the air duct 41 is reset and stored on both sides of the first charging part 2 without affecting the normal transfer of the mobile cart 1.

[0047] It should be added that storage slots 21 are provided on both sides of the first charging unit 2;

[0048] The air guide tube 41 includes a rotating rod 411 rotatably disposed in the receiving groove 21 .

[0049] It is easy to imagine that one end of the rotating rod 411 extends outside the receiving slot 21 and is fixedly connected to the magnetic attraction member 5;

[0050] The other end of the rotating rod 411 is provided with a return torsion spring fixed in the receiving slot 21;

[0051] The return torsion spring is used to store the air guide tube 41 in the storage groove 21 .

[0052] The reset torsion spring is used to drive the rotating rod 411 to reset when the magnetic element 5 is misplaced, and to store the air guide tube 41 in the storage groove 21 . It is easy to imagine that the elastic force of the reset torsion spring is smaller than the attraction force between the two magnetic elements 5 .

[0053] In this application, if Figure 4-5 As shown, the magnetic member 5 includes a swinging magnetic member 51 fixedly arranged at the ends of the two rotating rods 411 and a fixed magnetic member 52 fixedly arranged at both sides of the second charging part 3, wherein the swinging magnetic member 51 and the fixed magnetic member 52 are permanent magnets;

[0054] The N and S poles of the two swinging magnetic attracting members 51 are oriented in opposite directions;

[0055] The N and S poles of the two fixed magnetic attracting members 52 are facing oppositely;

[0056] The two swinging magnetic elements 51 attract each other with the fixed magnetic element 52 on the same side.

[0057] Through the above-mentioned structural setting, during the transfer process of the mobile cart 1, the first corresponding swinging magnetic component 51 and the fixed magnetic component 52 are of the same pole and repel each other, and the second corresponding swinging magnetic component 51 and the fixed magnetic component 52 are of opposite poles and attract each other.

[0058] The purpose of the above arrangement is to prevent the air guide tube 41 from extending when the swinging magnetic element 51 corresponds to the fixed magnetic element 52 for the first time, thereby preventing the subsequent normal transfer of the mobile vehicle 1.

[0059] It is easy to imagine that the output end of the heat dissipation component 4 is provided with an exhaust hose 42 connected to the air guide pipe 41 on one side;

[0060] The input end of the heat dissipation component 4 is provided with an air intake hose 43 connected to the air duct 41 on the other side. The heat dissipation component 4 forms a circulation between the first charging part 2 and the second charging part 3 through the air duct 41 and the exhaust hose 42 to avoid overheating of both during charging.

[0061] To achieve the above effect, the output section of the heat dissipation component 4 is provided with an air collecting portion 44 covering it;

[0062] The air collecting portion 44 is connected to the exhaust hose 42 .

[0063] A preferred implementation is that one of the swinging magnetic attraction member 51 and the fixed magnetic attraction member 52 is a permanent magnet, and the other is an electromagnet. When the electromagnet is not powered, the magnetic force between the permanent magnet and the electromagnet is smaller than the torsion force used for the reset torsion spring; and when the electromagnet is powered, the magnetic force between the permanent magnet and the electromagnet is larger than the torsion force used for the reset torsion spring; wherein the electromagnet synchronously powers the first charging part 2 and the second charging part 3.

[0064] The above arrangement avoids the situation where the air guide tube 41 extends out when the mobile vehicle 1 drives the first charging unit 2 to pass through each of the second charging units 3 without power supply.

[0065] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0066] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0067] In addition, "plurality" means two or more.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
