Description

Technical Field

[0001] This utility model relates to the field of electric vehicle support technology, and more specifically to an electric vehicle support structure. Background Technology

[0002] Electric vehicle support structures are components used for parking electric vehicles, generally employing either tilting or upright support designs. In tilting parking scenarios, the electric vehicle can lean directly against the displayed support structure, and can be folded up when not in use, similar to bicycle support structures. However, compared to bicycles, electric vehicles are significantly heavier. Tilting support designs, often using a single support leg structure, rely on a single support point in contact with the ground for support, presenting the following problems: While the support provides stability in the direction the electric vehicle is leaning against, the stability of this single support point is tested when the vehicle is subjected to external impacts. In the opposite direction, although the support needs to overcome the electric vehicle's center of gravity, external forces such as a sudden tipping or strong winds still pose a possibility of tipping over. Utility Model Content

[0003] This utility model provides a support structure for electric vehicles, the purpose of which is to increase the number of support points in the tilt support scheme.

[0004] The above objectives are achieved through the following technical solutions:

[0005] An electric vehicle support structure includes an outer support leg with a straight groove, an inner support leg inside the outer support leg, a first limiting post fixedly connected to the inner support leg and inserted into the straight groove, allowing the first limiting post to move within the straight groove, a mating hole on the outer support leg, a second limiting post fixedly connected to the lower end of the inner support leg and insertable into the mating hole, and the inner support leg retracting into the outer support leg. When the inner support leg extends from the outer support leg and the second limiting post is inserted into the mating hole, the inner support leg forms a second support position.

[0006] The inner support leg is detachably connected to the outer support leg.

[0007] The outer support leg has a first fitting piece fixedly attached to it, and the inner support leg has a second fitting piece fixedly attached to it. One of the first fitting piece and the second fitting piece has a hook and loop fastener with a bristle side, and the other has a hook and loop fastener with a nap side. When the inner support leg is retracted into the outer support leg, the first fitting piece faces and is fixedly attached to the second fitting piece.

[0008] The outer support leg has an elastic locking part fixed inside. When the inner support leg is retracted into the outer support leg, the inner support leg squeezes the locking part, causing the locking part to contract. The inner support leg is fixed by the friction between the locking part and the inner support leg.

[0009] The bottom of the outer support leg is fixed with a support foot.

[0010] A pad is fixed to the inner support leg. When the second limiting post can be inserted into the mating hole, the pad and the support leg support each other on the ground. The pad is closer to the side of the electric vehicle than the support leg.

[0011] The top of the outer support leg is fixed with a connecting protrusion, which is rotatably connected to the connector, which is used to fix it to the electric vehicle.

[0012] The connector includes a first fixing member, an outer support leg inserted into the first fixing member, a second fixing member fixed on the first fixing member, the outer support leg rotatably connected to the second fixing member, an inclined third fixing member fixed to the upper end of the first fixing member, an opening provided on the first fixing member for the outer support leg to rotate upward and backward to retract, and after the outer support leg is extended downward and forward, the third fixing member is inclined so that the bottom of the outer support leg is away from the electric vehicle, allowing the electric vehicle to lean against it, at which time the outer support leg leans against the first fixing member.

[0013] The upper end of the outer support leg is fixed with an elastic mating protrusion, and the lower end and rear end of the first fixing member are provided with grooves. After the outer support leg is rotated upward and backward to retract, the mating protrusion can be locked in the groove located at the rear end. After the outer support leg is extended downward and forward, the mating protrusion can be locked in the groove located at the lower end.

[0014] The protrusions are made of rubber.

[0015] The beneficial effects of this electric vehicle support structure are as follows:

[0016] By cooperating with the outer support leg and the deployable inner support leg, the outer support leg serves as the first support point, while the inner support leg, once deployed, forms a second support point, transforming the support point from a single point to a double point. This double support point significantly improves the stability of the vehicle when tilted and leaning against it, effectively preventing the vehicle from tipping over due to uneven force distribution at a single support point.

[0017] The inner support leg is designed to be retracted into the outer support leg. When the second support position is not needed, the inner support leg can be completely stored in the outer support leg without increasing the overall volume of the support structure. This avoids occupying the space for vehicle passage or parking and ensures the compactness of the structure.

[0018] When the inner support leg is deployed, the pad and the support foot of the outer support leg both contact the ground, with the pad positioned closer to the side of the electric vehicle. This design effectively resists the tendency of external forces to push the vehicle towards the leaning direction, further strengthening the anti-rollover capability of the support structure and improving the safety of vehicle parking.

Detailed Implementation

[0030] An electric vehicle support structure, reference Figure 1 In its supported state, it includes an outer support leg 1-1 serving as the first support. The left end of the outer support leg 1-1 has a longitudinally extending groove for placing the inner support leg 2-1. A straight slot 1-2 is provided at each of the front and rear ends of the lower side of the outer support leg 1-1, and the two straight slots 1-2 are symmetrical.

[0031] Two first limiting posts 2-2 are fixed to the front and rear ends of the lower side of the inner support leg 2-1. The two first limiting posts 2-2 are respectively inserted into two straight slots 1-2, and the first limiting posts 2-2 can move within the straight slots 1-2. This gives the inner support leg 2-1 degrees of freedom in the front-back direction and the rotational direction about the axis of the first limiting posts 2-2. The right end of the outer support leg 1-1 is provided with a mating hole 1-3. When the inner support leg 2-1 is retracted into the outer support leg 1-1, the mating hole 1-3 is face-to-face with the inner support leg 2-1 in the longitudinal state. This is so that the second limiting post 2-3 fixed to the lower end of the inner support leg 2-1 can be inserted into the mating hole 1-3 after movement.

[0032] For detailed explanations, please refer to [link / reference]. Figure 2 and 3 In the initial state, the inner support leg 2-1 is in the retracted position, and the first limiting post 2-2 is at the right end of the straight slot 1-2. To adjust to the extended state, move the upper part of the inner support leg 2-1 to the lower left. Figure 4 and 5 This causes the first limiting post 2-2 to be positioned at the left end of the straight slot 1-2, while the inner support leg 2-1 also rotates counterclockwise around the axis of the first limiting post 2-2 until the first limiting post 2-2 is horizontal. Then, refer to... Figure 6 and 7 Push the inner support leg 2-1 to the right until the first limiting post 2-2 is inserted into the mating hole 1-3, completing the unfolding of the inner support leg 2-1 and forming the second support.

[0033] The above are the necessary technical solutions for the core inventive point of extending the support position. The following are extensions to this necessary solution, forming a complete product:

[0034] Regarding the temporary fixation of the inner support leg 2-1, it is detachably connected to the outer support leg 1-1 in Embodiment 1: The top of the outer support leg 1-1 is fixed with a retaining part 1-4-3 made of elastic rubber. When the inner support leg 2-1 is retracted into the outer support leg 1-1, the top of the inner support leg 2-1 presses against the retaining part 1-4-3, causing the retaining part 1-4-3 to contract. The friction between the retaining part 1-4-3 and the inner support leg 2-1 is used to fix the inner support leg 2-1.

[0035] Example 2: A first adhesive piece 1-4-1 is fixedly connected to the inner side of the outer support leg 1-1, and a second adhesive piece 1-4-2 is fixedly connected to the inner support leg 2-1. One of the first adhesive piece 1-4-1 and the second adhesive piece 1-4-2 is a hook and loop fastener with a burr side, and the other is a hook and loop fastener with a nap side. When the inner support leg 2-1 is retracted into the outer support leg 1-1, the first adhesive piece 1-4-1 faces and is fixedly attached to the second adhesive piece 1-4-2.

[0036] Of course, Embodiment 1 and Embodiment 2 can be used in combination. Referring to Figure 10, in the retracted / folded state of the outer support leg 1-1, if the model of the electric vehicle can prevent the inner support leg 2-1 from moving in the direction of the electric vehicle in this state, then the solution that facilitates the display of the inner support leg 2-1 can be used, i.e., Embodiment 1. Otherwise, Embodiment 2 can be used.

[0037] Regarding Embodiment 1 for convenient display of the inner support leg 2-1: A support foot 1-6 can be fixedly attached to the bottom of the outer support leg 1-1. A pad 2-4 is fixedly attached to the inner support leg 2-1. When the inner support leg 2-1 is folded inside the outer support leg 1-1, the pad 2-4 protrudes from the outer support leg 1-1, making it convenient for the foot to step on the pad 2-4 to move the inner support leg 2-1 away from the outer support leg 1-1.

[0038] Example 2: The pad 2-4 has a groove so that a hand can be inserted into it to pull the inner support leg 2-1.

[0039] When the second limiting post 2-3 can be inserted into the mating hole 1-3, the pad 2-4 and the support foot 1-6 are supported on the ground together, with the pad 2-4 being closer to the side of the electric vehicle than the support foot 1-6. The outer support leg 1-1 is a conventional support solution, with the electric vehicle leaning against it. The added pad 2-4 can prevent external forces from pushing the electric vehicle to tilt in the opposite direction of the leaning direction.

[0040] When the inner support leg 2-1 is retracted, the foot pedal can be used to apply force towards the direction of the electric vehicle to disengage the second limiting post 2-3 from the mating hole 1-3, allowing the inner support leg 2-1 to rotate into the outer support leg 1-1.

[0041] The connection scheme between this utility model and the electric vehicle adopts conventional methods:

[0042] Example 1: A connecting protrusion 1-5 is fixedly connected to the top of the outer support leg 1-1. The connecting protrusion 1-5 is rotatably connected to the connector, which is used to fix it to the electric vehicle.

[0043] Example 2: The connector includes a first fixing member 3-1, an outer support leg 1-1 inserted into the first fixing member 3-1, a columnar second fixing member 3-2 fixed on the first fixing member 3-1, the second fixing member 3-2 passing through the outer support leg 1-1, allowing the outer support leg 1-1 to be rotatably connected to the second fixing member 3-2, an inclined third fixing member 3-3 fixed to the upper end of the first fixing member 3-1, and an opening provided on the first fixing member 3-1 for the outer support leg 1-1 to rotate upwards and backwards to retract, the retracted state as shown... Figure 10 As shown. After the outer support leg 1-1 unfolds downward and forward, the third fixing member 3-3 is tilted so that the bottom of the outer support leg 1-1 is away from the electric vehicle, allowing the electric vehicle to lean against it. At this time, the outer support leg 1-1 leans against the first fixing member 3-1.

[0044] The optimized outer support leg 1-1 has an elastic rubber protrusion 1-7 fixed to its upper end. The lower end and rear end of the first fixing member 3-1 are provided with grooves. After the outer support leg 1-1 rotates upward and backward to retract, the protrusion 1-7 can be locked in the groove at the rear end. After the outer support leg 1-1 unfolds downward and forward, the protrusion 1-7 can be locked in the groove at the lower end.

[0045] For optimized installations, if the structure is made of metal, the fixing method can be welding or threaded fasteners. If the structure is made of plastic, the fixing method can be thermoforming threaded fasteners.
