Description

Technical Field

[0001] The present invention belongs to the technical field of automobile manufacturing, and particularly relates to an automobile motor suspension mechanism. Background Art

[0002] The driving motor of an automobile is usually installed on the driving bridge frame of the vehicle frame by means of a suspension bracket. The suspension bracket and the motor are connected by bolts. When the vehicle body often travels on a vibrating road condition, or after the automobile has been running for a long time, the bolts will loosen due to crosstalk and the connection between the bolts and the suspension bracket will become loose, resulting in the connection between the motor and the vehicle frame shaking, thus affecting the normal driving operation of the motor. Summary of the Invention

[0003] The purpose of the present invention is to provide an automobile motor suspension mechanism to solve the problem of loose connection between the motor and the suspension mechanism.

[0004] The present invention provides the following technical solutions:

[0005] An automobile motor suspension mechanism includes a top plate, an upper suspension, a lower suspension, a connecting column and a transfer block; the two transfer blocks are fixedly arranged on the motor housing in an up-and-down opposite manner; both the upper suspension and the lower suspension include a tensioning body and a clamping arm integrally formed, the tensioning body is an arc-shaped elastic member concave inward toward the motor, the transfer block is locked on the tensioning body, the two clamping arms are symmetrically distributed on the left and right sides of the tensioning body, and pulling the clamping arm can cause the tensioning body to generate a tensioning deformation; the two connecting columns fixedly connect the upper suspension and the lower suspension, and the connecting columns are fixed on the clamping arms; the top plate is located at the top of the upper suspension, and the top plate fixedly connects the upper suspension and the vehicle frame.

[0006] Preferably, clamping grooves are arranged on the front and rear side walls of the tensioning body, and hooks matching the clamping grooves are arranged on the front and rear sides of the transfer block, and the hooks are embedded in the clamping grooves.

[0007] Preferably, the clamping groove is an arc-shaped groove body structure having the same curvature as the tensioning body.

[0008] Preferably, the bottom of the connecting column is welded to the clamping arm of the lower suspension, and the top of the connecting column is sequentially connected to the clamping arm of the upper suspension and the top plate by screws.

[0009] Preferably, a positioning sleeve is welded to the bottom of the clamping arm of the upper suspension, the inner diameter of the positioning sleeve matches the diameter of the connecting column, and the top of the connecting column can be inserted into the positioning sleeve.

[0010] Preferably, the length of the positioning sleeve is 10-15 mm.

[0011] The beneficial effects of the present invention are as follows: In the present invention, the motor is fixed to the upper suspension and the lower suspension through the adapter block, and the connecting column tightens the clamping arms of the upper suspension and the lower suspension, causing the curvature of the tension body in the middle of the suspension to become smaller and deform. The deformation of the tension body exerts a pulling force on the adapter block towards the side away from the motor, making the connection between the adapter block and the tension body more firm and tight, and there will be no loosening phenomenon between the two. The upper suspension and the lower suspension are symmetrical structures, and the pulling forces they exert on the motor are in opposite directions, enabling the two adapter blocks to be reliably locked to the upper suspension or the lower suspension; both the upper and lower tension bodies are in a tensioned state, and the upper suspension and the lower suspension are fixedly connected by a rigid connecting column. Therefore, the motor and the vehicle frame always maintain a fixed state, ensuring the reliability of the motor operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Embodiment 1

[0020] As Figures 1 to 4 shown, an automotive motor suspension mechanism is used to suspend and fix the motor to the vehicle frame to ensure a stable connection between the motor and the suspension mechanism. This suspension mechanism includes a top plate 1, an upper suspension 2, a lower suspension 3, a connecting column 4, and an adapter block 5. Two adapter blocks 5 are fixedly arranged up and down relative to the outer shell of the motor 6, and the adapter block 5 is used to connect the motor 6 with the upper suspension 2 and the lower suspension 3. As Figure 3 and Figure 4As shown in the figure, both the upper suspension 2 and the lower suspension 3 include an integrally formed tension body 7 and clamping arms 8. The tension body 7 is an arc-shaped stainless steel elastic member that is concave inward on the side of the motor 6. It has a certain elastic deformation amount. The two clamping arms 8 are symmetrically distributed on the left and right sides of the tension body 7. Pulling the clamping arms 8 toward the concave side of the tension body 7 can cause the tension body 7 to deform to a certain extent and become tensioned. The adapter block 5 is locked on the tension body 7, and the two connecting columns 4 are fixedly connected to the clamping arms 8 of the upper suspension 2 and the lower suspension 3 longitudinally. The top plate 1 is located at the top of the upper suspension 2, and the top plate 1 is fixedly connected to the upper suspension 2 and the vehicle frame, thereby suspending and fixing the motor 6 on the vehicle frame.

[0021] As Figure 2 shown in the figure, the adapter block 5 is fixedly connected to the tension body 7 through a snap structure. The specific form is as follows: clamping grooves 9 are provided on the front and rear side walls of the tension body 7. The clamping grooves 9 are arc-shaped groove structures with the same curvature as the tension body 7. Hooks 10 that match the clamping grooves 9 are provided on both the front and rear sides of the adapter block 5. The hooks 10 are made of stainless steel with a certain deformation amount. During installation, the hooks 10 are gently bent outward, aligned with the clamping grooves 9 and then inserted into the clamping grooves 9. When the tension body 7 is in a tensioned state, the clamping grooves 9 are also tensioned and deformed together with the tension body 7, so that the clamping grooves 9 further clamp the hooks 10 due to the curvature difference between the clamping grooves 9 and the hooks 10, enhancing the connection strength between the adapter block 5 and the tension body 7. After long-term use, the connection between the motor 6 and the suspension mechanism is firm and stable.

[0022] As Figure 1 shown in the figure, the bottom of the connecting column 4 is welded to the clamping arm 8 of the lower suspension 3, and the top of the connecting column 4 is connected to the clamping arm 8 of the upper suspension and the top plate 1 through screws in sequence. A positioning sleeve 11 is welded to the bottom of the clamping arm 8 of the upper suspension 2. The inner diameter of the positioning sleeve 11 matches the diameter of the connecting column 4, and the length of the positioning sleeve 11 is 10 - 15 mm. The top of the connecting column 4 can be inserted into the positioning sleeve 11. When assembling the connecting column 4 and the upper suspension 2, first pull the connecting column 4 fixed to the lower suspension 3 upward tightly, insert the top of the connecting column 4 into the positioning sleeve 11, and then tighten the screws to fix the top plate 1, the upper suspension 2 and the connecting column 4. The positioning sleeve 11 prevents the compressed connecting column 4 from shaking freely, making the assembly very convenient and labor-saving.

[0023] Embodiment 2

[0024] As Figure 5 shown in the figure, the difference between this embodiment and Embodiment 1 lies in the different connection methods between the adapter block 5 and the tension body 7. The adapter block 5 is fixedly connected to the tension body 7 through a bolt 12. When the tension body 7 is in a tensioned state, it exerts a pressure on the head of the bolt 12 in the direction away from the motor, making it not easy for the bolt 12 to move up and down and become loose. Therefore, after long-term use, the connection between the motor 6 and the suspension mechanism is still firm and reliable.

[0025] The installation method of this motor suspension mechanism is as follows: Connect the adapter block 5 located on the upper side of the motor 6 to the tensioning body of the upper suspension 2, and then pre-tighten the two clamping arms of the top plate 1 and the upper suspension 2 with screws to deform and tension the tensioning body, so as to be firmly connected to the adapter block 5. Then install the adapter block 5 located on the lower side of the motor 6 on the tensioning body of the lower suspension 3, pull the two connecting columns 4 welded to the clamping arms of the lower suspension 3, insert the top of the connecting column 4 into the positioning sleeve 11, and then continue to tighten the screws of the upper suspension 2 and the connecting column 4 to tension the tensioning body of the lower suspension 3, so that the adapter block 5 on the lower side is firmly locked on the tensioning body and is not prone to loosening after long-term use.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
