Description
Technical Field
The utility model belongs to the technical field of the frame of trackless vehicle, specifically be external electric automobile frame of battery.
Background
The frame of the electric automobile mainly plays a role in connecting and supporting various systems of the automobile. The frame main part of car generally includes two girders, and two girders set up side by side to be connected with a plurality of crossbeams between two girders, the profile of whole frame main part is a rectangle basically, and the one end of rectangle is the locomotive, and the other end is the rear of a vehicle. A plurality of space areas can be formed between the two main beams, the space areas can be used for installing and placing parts of each system of the automobile, and a transmission shaft can be arranged below the frame to drive wheels. The batteries used by the automobile are large in volume, and particularly for electric automobiles for carrying cargos, so the batteries are generally installed on the outer side of the frame main body in an overhanging mode and are mainly supported by the main beam, so that the main beam can bear the torque effect generated by the gravity of the batteries, the stability of the frame main body is influenced to a certain degree, and the service life of the frame main body is further shortened.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an external electric automobile frame of battery to frame girder receives the moment of flexure effect of battery easily and causes the problem that stability weakens among the solution prior art.
In order to achieve the purpose, the basic scheme of the utility model provides an electric automobile frame with an external battery, which comprises a frame main body, wherein the frame main body comprises two main beams arranged side by side, and a plurality of cross beams are fixedly connected between the two main beams; the middle part both sides of frame main part are provided with the battery installation department, one side of going towards the battery installation department on the girder is connected with vertical support frame, and the bottom downwardly extending of support frame is less than the bottom of girder, is connected with two supporting beam that set up side by side between the bottom of the support frame on two girders.
The principle and the beneficial effect of the basic scheme are as follows: a battery mounting portion is provided for mounting a bracket for supporting a battery. The support frame is arranged and used for supporting the battery. A supporting beam is arranged for transversely supporting the supporting frame and enhancing the stability of the bottom of the supporting frame.
When the frame is used, the cross beam is connected with the main beam to form a frame main body, the upper end of the support frame is connected and fixed with the main beam, the support beam is connected and fixed with the bottom of the support frame, then the support for supporting the battery is connected and installed on the battery installation part of the main beam, the battery is installed on the support for supporting the battery, at the moment, the battery is positioned at two sides of the frame main body, and the bending moment generated by the gravity of the battery on the support frame and the bending moment generated by the support beam on the support frame can be mutually offset, so that the bending moment effect borne by the support frame is reduced, the bending moment effect borne by the main beam; because a supporting beam is located the below of girder, when the transmission shaft of vehicle was installed at the middle part of frame main part, a supporting beam was located the below of transmission shaft to can utilize a supporting beam to support the transmission shaft fracture and fall off after with ground contact, and then need not alone to set up the protection band structure for the transmission shaft, reduced the installation setting of part.
Furthermore, the supporting beam is detachably connected with the supporting frame. The detachable connection mode is adopted, so that the connection and the detachment between the supporting beam and the supporting frame are facilitated, and the interference of the supporting beam to the maintenance work performed from the lower part of the frame is avoided.
Furthermore, two crossbeams are fixedly connected to the positions, between the battery installation parts, of the two main beams, and the two crossbeams are close to the two ends of the battery installation parts respectively. Through set up the crossbeam near the both ends at battery installation department, can strengthen the stability under the battery action of gravity of girder to make the difficult emergence of girder destroy.
Furthermore, the position department that lies in battery installation department towards locomotive one end on the girder is provided with along horizontal and the kink towards the both sides bending of frame main part. After the bending part is arranged, the forward movement of the bracket of the battery under the inertia effect can be blocked through the bending part, so that the bracket of the battery is prevented from colliding with a vehicle head and other parts; simultaneously, because the kink is crooked towards the both sides of frame main part, then, the battery is located centre of a circle one side of kink, when the vehicle turned, the battery can produce horizontal effort to the girder through the support to make the girder produce horizontal bending deformation, and the direction of this bending deformation is just in time opposite with the direction of buckling of kink, so, the setting up of kink can increase the supporting role of girder when the vehicle turns to the battery, improves the structural stability of girder.
Furthermore, the supporting beam is a hollow rectangular pipe. The gravity of the supporting beam is reduced, so that the overall weight of the frame is reduced.
Furthermore, the supporting beam is divided into a first supporting section and a second supporting section, the first supporting section and the second supporting section are coaxially arranged, one end of the first supporting section and one end of the second supporting section are mutually pivoted in the transverse direction, the other end of the first supporting section and the other end of the second supporting section are respectively connected with corresponding supporting frames, and an adjustable telescopic rod is hinged between the two supporting beams. After the supporting beam is divided into the first supporting section and the second supporting section, the distance between the two ends of the supporting beam can be changed by rotating the first supporting section and the second supporting section around the pivoting position, so that the distance of the supporting frames at the two ends of the supporting beam can be adapted to change, and the supporting beam and the supporting frame can be conveniently connected.
Furthermore, the adjustable telescopic rod comprises a sleeve, a first screw rod and a second screw rod are coaxially and threadedly connected to two ends of the sleeve, and the thread turning directions of the first screw rod and the second screw rod are opposite. Through sheathed tube rotation, make the sleeve pipe rotate with first screw rod and second screw rod relatively respectively to realize that first screw rod and second screw rod are toward being close to the sleeve pipe or keeping away from the sheathed tube direction removal simultaneously, thereby realize changing the length of adjustable telescopic link, conveniently adjust.
Further, the support frame passes through bolted connection with the girder. The support frame and the main beam are convenient to connect and operate in a bolt connection mode.
Furthermore, the support frame is a channel steel. The supporting beam is made of channel steel, so that the weight of the supporting beam can be reduced, and the weight of the whole frame can be reduced.
