Description

Technical Field

[0001] This utility model belongs to the field of battery technology, and in particular relates to an integrated battery controller quick-release structure for electric off-road motorcycles. Background Technology

[0002] In the prior art, the battery of an electric vehicle is usually connected to the controller through a circuit interface. For example, Chinese utility model patent with publication number "CN203707213U" entitled "A Battery Box Structure for an Electric Vehicle" discloses a battery box structure for an electric vehicle, including a battery box body, a controller cover, a controller box, and a guide rail A. The controller box is provided with a controller plug, the battery box body is provided with a contact A, and the controller cover is provided with a contact B. The controller cover is connected to the controller box, and the controller box engages with the contact A on the battery box body through contact B. The controller box also includes a guide rail B, which is located at the bottom of the battery box body. The battery box body is connected to the guide rail A through the guide rail B. The bottom of the controller box is provided with a sliding groove, and the sliding groove is provided with a fixing hole A. The bottom of the controller cover is provided with a fixing hole B, and the guide rail A is provided with a fixing hole C. The controller box is inserted into the guide rail A through the sliding groove, and the fixing holes A, B, and C overlap and are connected by screws.

[0003] However, the aforementioned patented products have the following technical defects: 1. The controller cover and controller box adopt a separate design. The controller cover and controller are mostly made of iron or plastic plates and are installed together by bolts. This structure requires connecting the interface on the controller cover and the module inside the controller first when wiring, resulting in too many wires, complicated operation, and poor heat dissipation; 2. There is no guiding structure when connecting the battery to the controller. When connecting, the shaking may cause poor contact and sparking, which poses a safety hazard and can easily damage the battery; 3. The disassembly and assembly structure of the controller is independent of the battery box. When the controller needs to be disassembled and maintained, the battery box on the outer side of the frame tube must be removed first, and then the controller on the inner side of the frame tube must be removed. Since the controller is usually installed in a deep position inside the frame tube, this method of disassembling the controller is very troublesome. This not only brings great inconvenience to the disassembly and maintenance of the controller, but also hinders the installation of the controller. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated battery controller quick-release structure for electric off-road motorcycles to solve the technical problems of excessive wiring, poor heat dissipation, unstable connection positioning, and inconvenient disassembly and assembly of existing battery controllers.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an integrated battery controller quick-release structure for electric off-road motorcycles, comprising a controller body and a battery body. The controller body includes an integrally formed controller box and a controller cover. The controller cover and the battery body are provided with mutually cooperating circuit interfaces and a guide mechanism for facilitating the connection of the circuit interfaces.

[0006] Preferably, both the controller box and the controller cover are made of aluminum and are integrally die-cast.

[0007] Preferably, the circuit interface includes a first contact unit fixed in the controller body and electrically connected to the controller body, and a second contact unit located at the end of the battery body and electrically connected to the battery body, wherein the controller body is engaged with the second contact unit on the battery body through the first contact unit.

[0008] Preferably, the controller box has a cavity for accommodating the control module and the first contact unit, and the controller cover has a slot for the first contact unit to protrude from the surface of the controller cover. The control module and the first contact unit are wired together within the controller body.

[0009] Preferably, the bottom of the battery body has a protruding mounting portion, and the second contact unit is arranged on the mounting portion.

[0010] Preferably, the guide mechanism includes an outward protrusion disposed on the side of the controller cover away from the controller box and a groove formed at the bottom of the battery body, wherein the outward protrusion and the groove are matched.

[0011] Preferably, the top of the protrusion is designed with an arc-shaped chamfer, and the diameter of the opening of the groove gradually decreases relative to the bottom diameter, forming a trapezoidal inner groove, and the corner of the inner groove wall matches the contour of the protrusion.

[0012] Preferably, the protrusion and the groove are arranged on one side of the circuit interface.

[0013] Preferably, the controller cover and the battery body are detachably connected by a fixing component.

[0014] Preferably, the fixing component includes fixing bolts, the controller cover plate has a plurality of positioning holes, the battery body has threaded holes that match the positioning holes, and the fixing bolts pass through the positioning holes and are screwed into the threaded holes to install the controller box on the bottom of the battery body through the controller cover plate.

[0015] Compared with the prior art, the present invention has the following advantages through the above technical solution: 1. By setting a controller cover plate integrally formed on the controller box, the two constitute the controller body. The integral forming method allows the control module inside the controller box and the first contact unit protruding from the controller cover plate to complete the wiring inside the controller body, thus eliminating the need for additional wiring. This eliminates the steps of connecting the interface on the controller cover plate and wiring the module inside the controller. When connecting with the battery body, it is only necessary to connect the first contact unit on the controller box and the second contact unit on the battery body to form a circuit. The structure is simple and does not require too many wirings, solving the technical problem of excessive wiring in the existing battery controller matching structure. At the same time, both the controller box and the controller cover plate are made of aluminum, which has a good heat dissipation effect. In use, the integrally formed controller body is installed in the vehicle frame, and the heat dissipation is completed quickly through the heat dissipation channel in the vehicle frame, solving the technical problem of poor heat dissipation effect in the existing battery controller matching structure.

[0016] By setting a guiding mechanism, the battery body and the controller can be accurately connected, avoiding arcing, improving the safety and stability of installation, and ensuring that the battery is not damaged during installation. At the same time, the guiding mechanism can also eliminate the rotational force of the motor during operation, solving the technical problem of unstable connection and positioning between the battery body and the controller in the existing battery controller mating structure.

[0017] By using a fixing component to connect the battery body and the controller, the two can be integrated into a single unit. During use, when the controller needs to be removed for maintenance, simply remove the battery body from the side of the vehicle. Since the rear connection of the battery body is connected to the controller, the controller will also be removed at the same time. Then, simply release the fixing component used to connect the battery body and the controller to remove the controller separately. To install the controller, simply fix it under the battery body first and then install it into the vehicle. This allows for the coordinated installation and removal of the battery body and the controller, greatly facilitating the installation, use, disassembly, and maintenance of the controller, and solving the technical problem of the inconvenience of disassembling and installing the existing battery controller with its integrated structure.

[0023] like Figure 1-6 The diagram shows an integrated battery controller quick-release structure for electric off-road motorcycles, comprising a controller body 1 and a battery body 2. The controller body 1 includes an integrally formed controller box 101 and a controller cover 102. The controller cover 102, integrally formed with the controller box 101, constitutes the controller body 1. This integral forming allows the control module within the controller box 101 and the first contact unit 3 protruding from the controller cover 102 to be wired within the controller body 1, eliminating the need for additional wiring. This eliminates the steps of connecting the interface on the controller cover 102 and wiring the module within the controller. When connecting to the battery body 2, only the controller needs to be... The first contact unit 3 on box 101 and the second contact unit 4 on battery body 2 can be connected to form a circuit. The structure is simple and does not require too much wiring, which solves the technical problem of excessive wiring in the existing battery controller matching structure. The controller cover plate 102 and battery body 2 are provided with mutually cooperating circuit interfaces and a guide mechanism to facilitate the connection of the circuit interfaces. The mutually cooperating circuit interfaces enable the controller body 1 and battery body 2 to be electrically connected, while the guide mechanism enables the battery body 2 and controller body 1 to be accurately connected, avoiding the generation of arcing, improving the safety and stability during installation, and ensuring that the battery is not damaged during installation. At the same time, the setting of the guide mechanism can also eliminate the rotational force of the motor during operation.

[0024] like Figure 1-3 As shown: Both the controller box 101 and the controller cover 102 are made of aluminum and are integrally die-cast. The controller box 101 is located at the bottom of the controller cover 102. The four edges of the controller cover 102 protrude from the upper surface of the controller box 101, forming a bolt positioning part for connecting the battery body 2. When the controller body 1 and the battery body 2 are aligned and inserted, the several connecting holes provided on the bolt positioning part correspond to the threaded holes on the side of the battery body 2, so as to facilitate the installation of the controller body 1.

[0025] like Figure 2-5 As shown: The circuit interface includes a first contact unit 3 fixed inside the controller body 1 and electrically connected to the controller body 1, and a second contact unit 4 located at the end of the battery body 2 and electrically connected to the battery body 2. The controller body 1 is connected to the second contact unit 4 on the battery body 2 through the first contact unit 3. The first contact unit 3 and the second contact unit 4 are male and female, respectively. When the battery body 2 and the controller body 1 are connected, the first contact unit 3 is inserted into the second contact unit 4 to form a circuit. This plugging method is simple and fast and does not require too much wiring, making it easy to install.

[0026] like Figure 5As shown: The controller box 101 has a cavity for accommodating the control module and the first contact unit 3. A through-hole is formed on one side of the cavity. The controller socket connected to the controller body 1 extends to the outside of the controller box 101 through the through-hole. The controller cover 102 has a slot for the first contact unit 3 to protrude from the surface of the controller cover 102. The slot is connected to the cavity to facilitate wiring. The first contact unit 3 has a plate body larger than the diameter of the slot, so that the first contact unit 3 is confined inside the slot and will not come out of the controller body 1. The control module and the first contact unit 3 are wired inside the controller body 1.

[0027] like Figure 2 As shown: A protruding mounting portion 201 is formed on the bottom of the battery body 2. The mounting portion 201 is integrally formed on the battery body 2. The second contact unit 4 and the groove 6 are both arranged on the mounting portion 201 to facilitate the alignment and installation of the battery body 2 and the controller body 1.

[0028] like Figure 6 As shown: The guiding mechanism includes an outward protrusion 5 located on the side of the controller cover 102 away from the controller box 101 and a groove 6 formed at the bottom of the battery body 2. The outward protrusion 5 extends from the upper surface of the controller cover 102 to one side and the two are integrally formed. The groove 6 is formed by recessing from the bottom wall of the mounting part 201 to one side. The outward protrusion 5 and the groove 6 match to improve the guiding accuracy. The specific shape and style of the outward protrusion 5 and the groove 6 can be selected according to actual needs.

[0029] like Figure 6 As shown: The top of the protruding part 5 has an arc-shaped chamfer design. The chamfer of the protruding part 5 serves as a guide and limit when inserted into the groove 6, facilitating insertion. The diameter of the opening of the groove 6 gradually decreases relative to the bottom diameter, forming a trapezoidal inner groove. The corners of the inner groove wall match the contour of the protruding part 5. The protruding part 5 gradually decreases in size from the upper surface of the controller cover plate 102 outwards, while the groove 6 gradually decreases in size from the bottom wall of the mounting part 201 inwards. The gradually decreasing shape and matching form achieve the guiding purpose by contacting the male and female connectors before they are fully engaged.

[0030] When the battery body 2 and the controller body 1 are assembled, the protrusion 5 and the groove 6 first make contact and form a guide line after contact. The first contact unit 3 and the second contact unit 4 rely on the guide line to form a docking, so that the docking of the two is more accurate and can effectively eliminate the sparking phenomenon.

[0031] When the controller body 1 is installed below the battery body 2, the protrusion 5 extends into the groove 6 to increase the stability of the connection between the controller and the battery body.

[0032] like Figure 2-3As shown: the protrusion 5 and the groove 6 are arranged on one side of the circuit interface, that is, the protrusion 5 is set on one side of the first contact unit 3 and the groove 6 is set on one side of the second contact unit 4, and their vertical positions correspond to each other.

[0033] like Figure 1-2 As shown: The controller cover 102 and the battery body 2 are detachably connected by a fixing component. It should be noted that this structure is mainly suitable for side-pull batteries, and its purpose is to enable the quick removal of the controller body 1.

[0034] like Figure 2 As shown: The fixing component includes fixing bolts. Several positioning holes are opened on the controller cover plate. Several positioning holes are opened on the bolt positioning part. The battery body 2 is provided with threaded holes that match the positioning holes. The fixing bolts pass through the positioning holes and are screwed into the threaded holes. The controller box 101 is installed at the bottom of the battery body 2 through the controller cover plate 102. Generally, the controller body 1 can be firmly installed under the battery body 2 with three fixing bolts. When it is necessary to remove the controller body 1, first remove the battery body 2, then pull out the controller body 1, and then remove the three screws to remove it. The disassembly of the controller body 1 is very convenient.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
