Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle drive component installation technology, and specifically refers to a suspended anti-fall-off motor cover mechanism and electric vehicle drive device. Background Technology

[0002] In recent years, new energy vehicles have been developing rapidly, and the demand for electric-driven construction machinery vehicles is also increasing. The traditional engine + gearbox power transmission route is gradually being replaced by the route represented by electric motor + gearbox. Existing motors are usually independently arranged and fixed only with bolts. However, under frequent vibration conditions or after long-term use, the bolts are prone to loosening or even falling off, causing the motor to fall off.

[0003] The existing technology, with its separate arrangement of the motor and gearbox, results in a dispersed structure, low compactness, large space occupation, and is not conducive to the overall layout and maintenance of the machine. Simply increasing the number of bolts or adding anti-loosening washers would increase the complexity of installation. Therefore, it is necessary for those skilled in the art to solve the above problems. Utility Model Content

[0004] This utility model provides a suspended anti-fall motor cover mechanism, mainly solving the problem that in the prior art, the motor is fixed separately from the gearbox, making it prone to falling and being damaged under vibration. Additionally, the prior art's motor installation occupies a large space, which is detrimental to the overall machine layout and maintenance. Another aspect of this utility model also provides an electric vehicle drive device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A suspended anti-fall motor cover mechanism, comprising:

[0007] The first bracket has a first mounting ring seat on it;

[0008] The second bracket is detachably connected to the first bracket, and the second bracket is provided with a second mounting position.

[0009] The first bracket and the second bracket are detachably connected. A locking protrusion structure is provided between the first bracket and the second bracket. The locking protrusion structure includes a first locking groove provided on the first bracket and a first locking block provided on the second bracket, or a first locking block provided on the first bracket or a first locking groove provided on the second bracket. The first locking block is adapted to the first locking groove and is locked in the first locking groove.

[0010] In some embodiments, the first bracket is provided with two fixed supports, which are spaced apart and arranged in parallel, and the first slot is provided on the two fixed supports.

[0011] In some embodiments, the first locking block is disposed on the second bracket, and the second bracket is provided with two first limiting protrusions, which abut against the two fixed supports. The two first limiting protrusions are located between the two fixed supports or on the outside of the two fixed supports.

[0012] In some embodiments, the fixed support is provided with a first mounting surface, the first mounting surface is provided with a first fixing hole, the second bracket is provided with a second fixing hole corresponding to the position of the first fixing hole, and the second bracket can be fitted and fixed to the first mounting surface.

[0013] In some embodiments, the fixed support is provided with a second limiting protrusion, and the second limiting protrusion is provided with a preset distance from the first mounting surface to form the first slot.

[0014] In some embodiments, the second limiting protrusion is provided with a third fixing hole, and the second bracket is provided with a fourth fixing hole. When the second bracket is installed on the first bracket, the third fixing hole and the fourth fixing hole are positioned correspondingly.

[0015] In some embodiments, the first limiting protrusion is provided with a through fifth fixing hole.

[0016] In some embodiments, the fixed support is arranged perpendicularly to the first mounting ring.

[0017] In some embodiments, the present invention also provides a tram drive device, comprising:

[0018] The suspended anti-fall motor cover mechanism as described in the above embodiments;

[0019] The gearbox assembly is detachably mounted on the second bracket;

[0020] A drive motor is detachably mounted on the first mounting ring of the first bracket, and the output end of the drive motor is connected to the input end of the gearbox assembly.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This application provides a locking protrusion structure between the first bracket and the second bracket. When the screws or bolts of the connecting and fixing structure of the first bracket and the second bracket fall off due to vibration, the locking protrusion structure can ensure that the drive motor will not fall off and be damaged. At the same time, by setting the first bracket and the second bracket, the drive motor and the gearbox are installed as a whole, ensuring the coaxiality of the output end of the drive motor and the input end of the gearbox assembly. Moreover, its installation structure is more compact, occupies less space, facilitates the layout and maintenance of vehicle components, and improves the vibration resistance of the entire device.

[0023] Additional aspects and advantages of this application will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of this application. Attached Figure Description

[0033] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the embodiments, unless otherwise stated, the terms "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the present application must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.

[0034] like Figure 1As shown, this utility model provides a suspended anti-fall motor cover mechanism, comprising: a first bracket 100, on which a first mounting ring seat 101 is provided; a second bracket 200, detachably connected to the first bracket 100, and the second bracket 200 is provided with a second mounting position; the first bracket 100 and the second bracket 200 are detachably connected, wherein a locking protrusion structure is provided between the first bracket 100 and the second bracket 200, the locking protrusion structure is mainly used for locking and fixing the first bracket 100 and the second bracket 200, and its main feature is that when the screw fixing the first bracket 100 and the second bracket 200 is loose, the first bracket 100 will not move relative to the second bracket 200 in the direction of its own gravity;

[0035] Specifically, such as Figure 4 and Figure 7 As shown, the card protrusion structure includes a first card groove 1022 disposed on the first bracket 100 and a first card block 203 disposed on the second bracket 200. The first card groove 1022 has a certain width and depth, and the first card block 206 matches the size of the first card groove 1022 and is engaged in the first card groove 1022.

[0036] Alternatively, as a variation of the above embodiment, the first card block 206 can be disposed on the first bracket 100, and the first card slot 1022 can be disposed on the second bracket 200, which can also achieve the above purpose.

[0037] In this application, by setting a locking protrusion structure, it is possible to effectively prevent the first bracket 100 and the second bracket 200 from detaching from each other when the bolts or screws between the first bracket 100 and the second bracket 200 become loose. The second bracket 200 can still lock and fix the first bracket 100 in the direction of its own gravity, thereby preventing the first bracket 100 or the equipment set on the first bracket 100 from detaching from the second bracket 200 and preventing mechanical equipment from falling and being damaged.

[0038] In one embodiment, two fixed supports 102 are provided on the first bracket 100. The two fixed supports 102 are spaced apart and parallel to each other. It should be noted that the two fixed supports 102 are symmetrically arranged to ensure balanced force distribution and a more stable locking structure. First slots 1022 are respectively provided on the two fixed supports 102, and their openings are as follows: Figure 4 The downward opening is shown. In this embodiment, the fixed support 102 is a vertically distributed L-shaped structure, and its horizontal support arm, which engages with the second bracket 200, has a certain length, providing space between the first mounting ring seat 101 of the first bracket 100 and the second mounting position on the second bracket 200.

[0039] In one embodiment, the first locking block 206 is disposed on the second bracket 200, and the second bracket 200 is provided with two first limiting protrusions 201, which respectively abut against two corresponding fixed supports 102. In this embodiment, the two first limiting protrusions 201 are located inside the two fixed supports 102, thereby ensuring that the second bracket 200 and the first bracket 100 are in contact with each other. Figure 7 The left-right swinging motion, as shown, ensures that the second bracket 200 and the first bracket 100 do not move relative to each other along the length of the first slot 1022. In this embodiment, as... Figure 6 As shown, the second bracket 200 includes a main body and two fixed legs 204. The first thickness 205 of the main body of the second bracket 200 is the same as the width of the first slot 1022, so that the first bracket 100 can be snapped onto the second bracket.

[0040] Optionally, the two first limiting protrusions 201 can also be positioned on the outside of the two fixed supports 102 to abut against each other, which can also make the second bracket 200 and the first bracket 100 remain relatively stationary in the length direction of the first slot 1022.

[0041] Furthermore, such as Figure 2 As shown, a first mounting surface 1023 is provided on the fixed support 102, a first fixing hole 1024 is provided on the first mounting surface 1023, and a second fixing hole 203 is provided on the second bracket 200, as follows. Figure 5 As shown, the number of second fixing holes 205 matches the number of first fixing holes 1024, and their positions correspond. The second bracket 200 can be fitted and fixed on the first mounting surface 1023, and the two are locked and fixed by bolts or screws.

[0042] In one embodiment, such as Figure 4 As shown, a second limiting protrusion 1021 is provided on both fixed supports 102. The second limiting protrusion 1021 has an L-shaped structure. A preset distance 1025 is provided between the second limiting protrusion 1021 and the first mounting surface 1023, thereby forming a first slot 1022.

[0043] Furthermore, a third fixing hole 1026 is provided on the second limiting protrusion 1021, and a fourth fixing hole (not shown in the figure) is provided on the second bracket 200. When the second bracket 200 and the first bracket 100 are snapped together, the third fixing hole 1026 corresponds to the fourth fixing hole. Figure 1 and Figure 2 As shown, bolts are used to connect the first bracket 100 and the second bracket 200 through the third fixing hole 1026 and the fourth fixing hole, thereby further strengthening the fixing structure between the first bracket 100 and the second bracket 200.

[0044] Furthermore, a fifth fixing hole 202 is provided on the first limiting protrusion 201. Simultaneously, to form a second mounting position, a fifth fixing hole 202 is also provided on the main body of the second support 200, such as... Figure 7 As shown, the four fifth fixing holes 202 form the second mounting position.

[0045] In one embodiment, since the first bracket 100 is used for the installation of the drive motor 103 and the second bracket 200 is used for the installation of the gearbox assembly 300, when the second bracket 200 is fixed on the first bracket 100, the second bracket 200 is fitted onto the first mounting surface 1023. In order to ensure the coaxiality between the two, the fixed support 102 is set vertically relative to the first mounting ring 101.

[0046] In one embodiment, the present invention also provides a tram drive device, mainly comprising:

[0047] The suspended anti-fall motor cover mechanism in the above embodiments;

[0048] The gearbox assembly 300 is detachably mounted on the second bracket 200 via the fifth fixing hole 202;

[0049] The drive motor 103 is detachably mounted on the first mounting ring seat 101 of the first bracket 100 and fixed by bolts or screws. The output end of the drive motor 103 is connected to the input end of the gearbox assembly 300. The output shaft of the drive motor 103 and the input shaft of the gearbox assembly 300 are coaxially arranged. The gearbox assembly 300 and the drive motor 103 are connected by the first bracket 100 and the second bracket 200 to achieve the overall installation of the gearbox assembly 300 and the drive motor 103, thereby ensuring the coaxiality of the output shaft of the drive motor 103 and the input shaft of the gearbox assembly 300.

[0050] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model. These improvements and modifications should also be considered within the scope of protection of this utility model.
