Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, and in particular to a front module fixture for an automotive chassis. Background Technology

[0002] Nowadays, with the development of automotive technology, automobiles have increasingly more functions, and the number of automotive parts has also increased. The front chassis module fixture, as a heavy-duty component in an automobile, is typically installed by technicians using assisted robotic arms.

[0003] Currently, when installing front chassis modules, the impact of assembly area and assembly efficiency needs to be considered comprehensively. If multiple front chassis modules are laid flat, technicians can easily grasp them, resulting in high assembly efficiency, but the placement area (i.e., assembly area) of the front chassis modules is relatively large. If multiple front chassis modules are placed on different shelves, the assembly area can be effectively reduced, but it is inconvenient for technicians to remove the front chassis modules from the shelves, resulting in lower assembly efficiency.

[0004] Therefore, there is an urgent need for a device for loading the front chassis module, which can reduce the assembly area, improve the convenience for technicians to grab the front chassis module, and thus improve assembly efficiency. Summary of the Invention

[0025] The technical solutions provided by the embodiments of this application have at least the following beneficial effects:

[0026] This application provides a front module mounting fixture for an automobile chassis. The bottom support mechanism of the front module is hinged to a horizontal frame. The middle support mechanism includes a first middle support frame, a first gas spring, a second middle support frame, and a second gas spring.

The two ends of the third gas spring are hinged to the first upper support frame and the crossbeam assembly, respectively. The two ends of the fourth gas spring are hinged to the second upper support frame and the crossbeam assembly, respectively. This allows four front chassis modules to be placed sequentially on top of the horizontal frame, the bottom support mechanism, the middle support mechanism, and the top support mechanism, eliminating the need to lay multiple front chassis modules flat and reducing the assembly area. Furthermore, when technicians remove the topmost front chassis module, the support frame supporting it changes from parallel to the horizontal frame to perpendicular to it under the action of a gas spring. This allows technicians to directly grasp the front chassis module placed on the next support frame, improving ease of access and thus increasing assembly efficiency.

[0056] The following section will introduce each part of the front module mounting of the automobile chassis.

[0057] I. Outer Frame 1

[0058] The outer frame 1 is a supporting component in the front module fixture of the automobile chassis.

[0059] like Figure 1 As shown, the outer frame 1 includes a horizontal frame 11, a vertical beam group 12, a horizontal beam group 13, and an anti-slip frame 14.

[0060] Horizontal Frame 11

[0061] The horizontal frame 11 is the base of the outer frame 1.

[0062] like Figure 1 As shown, the horizontal frame 11 is a rectangular frame, and the upper surface of the horizontal frame 11 has a hinge base 11e.

[0063] Optionally, the horizontal frame 11 may include a horizontal frame body 111, a first beam frame 112, a second beam frame 113, a third beam frame 114, a fourth beam frame 115, a fifth beam frame 116, a sixth beam frame 117, a seventh beam frame 118, and an eighth beam frame 119.

[0064] The horizontal frame body 111 is a rectangular frame, and has a first edge 111a, a second edge 111b, a third edge 111c, and a fourth edge 111d. The two ends of the first beam 112 are connected to the first edge 111a and the third edge 111c, respectively. The two ends of the second beam 113 are connected to the first edge 111a and the third edge 111c, respectively. The two ends of the third beam 114 are connected to the second edge 111b and the fourth edge 111d, respectively. The two ends of the fourth beam 115 are connected to the second edge 111b and the fourth edge 111d, respectively. The fifth beam 116 is located between the first edge 111a and the third beam. Between 114, the two ends of the fifth beam frame 116 are connected to the first beam frame 112 and the second beam frame 113 respectively. The sixth beam frame 117 is located between the first edge 111a and the third beam frame 114. The two ends of the sixth beam frame 117 are connected to the second edge 111b and the second beam frame 113 respectively. The seventh beam frame 118 is located between the third edge 111c and the fourth beam frame 115. The two ends of the seventh beam frame 118 are connected to the first beam frame 112 and the second beam frame 113 respectively. The eighth beam frame 119 is located between the third edge 111c and the fourth beam frame 115. The two ends of the eighth beam frame 119 are connected to the second edge 111b and the second beam frame 113 respectively.

[0065] Among them, the first beam frame 112, the second beam frame 113, the fifth beam frame 116, the sixth beam frame 117, the seventh beam frame 118 and the eighth beam frame 119 are all parallel to the first edge 111a, and the third beam frame 114 and the fourth beam frame 115 are all parallel to the second edge 111b.

[0066] Optionally, the horizontal frame body 111, the first beam frame 112, the second beam frame 113, the third beam frame 114, the fourth beam frame 115, the fifth beam frame 116, the sixth beam frame 117, the seventh beam frame 118 and the eighth beam frame 119 can all be hollow beam frames.

[0067] In this way, the weight of the horizontal frame 11 can be reduced while ensuring that the horizontal frame 11 has high mechanical strength.

[0068] like Figure 2 As shown, the upper surface of the horizontal frame 11 has a first fixing seat 11f, a second fixing seat 11g, and a third fixing seat 11h. The first fixing seat 11f is located on the upper surface of the fifth beam frame 116 and is connected to the fifth beam frame 116. The second fixing seat 11g is located on the side of the first fixing seat 11f away from the first beam frame 112 and is connected to the upper surface of the fifth beam frame 116. The third fixing seat 11h is located between the first beam frame 112 and the second beam frame 113 and is connected to the upper surface of the third beam frame 114.

[0069] The first fixed seat 11f is used to engage the steering gear tie rod of the first chassis front module, the second fixed seat 11g is used to engage the front longitudinal beam mounting bracket of the first chassis front module, and the third fixed seat 11h is used to engage the front control arm of the first chassis front module. The first chassis front module is a chassis front module placed between the horizontal frame 11 and the bottom support mechanism 2.

[0070] Optionally, there can be multiple first fixing seats 11f, second fixing seats 11g, and third fixing seats 11h. Multiple first fixing seats 11f are symmetrically arranged about the bottom support frame 22, multiple second fixing seats 11g are symmetrically arranged about the bottom support frame 22, and multiple third fixing seats 11h are symmetrically arranged about the bottom support frame 22.

[0071] In this way, the first chassis front module can be placed on the horizontal frame 11, and the first chassis front module can be limited by the first fixed seat 11f, the second fixed seat 11g and the third fixed seat 11h to prevent the first chassis front module from moving.

[0072] For example, such as Figure 1 As shown, the distances between the first beam frame 112 and the fourth edge 111d, the distances between the first beam frame 112 and the second beam frame 113, and the distances between the second beam frame 113 and the second edge 111b are the same. The distances between the third beam frame 114 and the first edge 111a, the distances between the third beam frame 114 and the fourth beam frame 115, and the distances between the fourth beam frame 115 and the third edge 111c are the same.

[0073] Optionally, the upper surface of the horizontal frame 11 may have multiple protective pads 1a, one of which is located between the first beam frame 112 and the fourth edge 111d and is connected to the upper surface of the third beam frame 114, and the other is located between the first beam frame 112 and the fourth edge 111d and is connected to the upper surface of the fourth beam frame 115.

[0074] This prevents the horizontal frame 11 from directly contacting the front module of the first chassis, thereby avoiding scratching the front module of the first chassis.

[0075] Vertical beam group 12

[0076] The vertical beam assembly 12 is a component of the outer frame 1.

[0077] like Figure 1As shown, the vertical beam group 12 includes a first vertical beam 121, a second vertical beam 122, a third vertical beam 123, a fourth vertical beam 124, a fifth vertical beam 125, and a sixth vertical beam 126. The first vertical beam 121, second vertical beam 122, third vertical beam 123, fourth vertical beam 124, fifth vertical beam 125, and sixth vertical beam 126 are all placed vertically. The first vertical beam 121, second vertical beam 122, third vertical beam 123, and fourth vertical beam 124 are respectively connected to the four apex corners of the horizontal frame 11. The fifth vertical beam 125 is located between the first vertical beam 121 and the second vertical beam 126. The vertical beams 122 are located between the third vertical beams 123 and the fourth vertical beams 124 and are connected to the horizontal frame 11.

[0082] The crossbeam assembly 13 is a component of the outer frame 1.

[0083] like Figure 1As shown, the crossbeam assembly 13 includes a first crossbeam 131, a second crossbeam 132, a third crossbeam 133, and a fourth crossbeam 134. These four crossbeams are placed horizontally. The two ends of the first crossbeam 131 are connected to the first vertical beam 121 and the fifth vertical beam 125, respectively. The two ends of the second crossbeam 132 are connected to the third vertical beam 123 and the sixth vertical beam 126, respectively. The two ends of the third crossbeam 133 are... The second vertical beam 122 and the fifth vertical beam 125 are not connected.

[0084] The distances from the first crossbeam 131 and the third crossbeam 133 to the horizontal frame 11 are both of the first value, and the distances from the second crossbeam 132 and the fourth crossbeam 134 to the horizontal frame 11 are both of the second value. The first value is less than the second value. The distances from the first spring connecting seat 125a and the third spring connecting seat 126a to the horizontal frame 11 are both less than the first value. The distances from the second spring connecting seat 125b and the fourth spring connecting seat 126b to the horizontal frame 11 are both less than the second value. The first baffle 124n is located on the surface of the fourth vertical beam 124 near the third vertical beam 123 and extends from the surface of the fourth vertical beam 124 near the second vertical beam 122.

[0085] Optionally, the relationship between the first value and the second value can satisfy the following relationship: the first value is 2 / 3 of the second value.

[0086] Optionally, the crossbeam assembly 13 may also include a fifth crossbeam 135 and a sixth crossbeam 136.

[0087] like Figure 3 As shown, the fifth horizontal beam 135 and the sixth horizontal beam 136 are both placed horizontally. The two ends of the fifth horizontal beam 135 are connected to the second vertical beam 122 and the fourth vertical beam 124 respectively, and are parallel to the horizontal frame 11. The two ends of the sixth horizontal beam 136 are connected to the other ends of the fifth horizontal beam 135 and the seventh vertical beam 127 respectively. The length of the connecting rod 21 is the third value, the length of the seventh vertical beam 127 is equal to the third value, and the distance from the fifth horizontal beam 135 to the horizontal frame 11 is equal to the third value.

[0088] Optionally, the relationship between the third value and the second value can satisfy the following relationship: the third value is 1 / 3 of the second value.

[0089] Anti-slip rack 14

[0090] Anti-slip bracket 14 is a component in the outer frame 1 used to increase the friction between the outer frame 1 and the ground.

[0091] like Figure 1 As shown, the anti-slip bracket 14 is located below the horizontal frame 11 and is connected to the horizontal frame 11.

[0092] Optionally, a rubber pad may be provided on the surface of the anti-slip bracket 14 away from the horizontal frame 11.

[0093] This increases the coefficient of friction between the anti-slip bracket 14 and the ground, thereby preventing the front module mounting of the vehicle chassis from sliding relative to the ground.

[0094] II. Underlying Support Structure 2

[0095] The bottom support mechanism 2 is a component in the front module fixture of the automobile chassis used to snap onto the second front module of the chassis.

[0096] like Figure 1 As shown, the bottom support mechanism 2 includes a connecting rod 21 and a bottom support frame 22. Both the connecting rod 21 and the bottom support frame 22 are located above the horizontal frame 11. One end of the connecting rod 21 is hinged to the hinge base 11e, and the bottom support frame 22 is connected to the other end of the connecting rod 21. When the connecting rod 21 is perpendicular to the horizontal frame 11, the bottom support frame 22 is parallel to the horizontal frame 11.

[0097] Optionally, such as Figure 3 As shown, the bottom support mechanism 2 also includes a fourth fixed seat 2f, a fifth fixed seat 2g, and a sixth fixed seat 2h. The fourth fixed seat 2f is connected to the other end of the seventh vertical beam 127. The fifth fixed seat 2g is located on the upper surface of the sixth horizontal beam 136 and is connected to the sixth horizontal beam 136. The sixth fixed seat 2h is located on the upper surface of the fifth horizontal beam 135 and is connected to the fifth horizontal beam 135.

[0098] Among them, the fourth fixed seat 2f is used to clamp the steering gear tie rod of the second chassis front module, the fifth fixed seat 2g is used to clamp the front longitudinal beam mounting bracket of the second chassis front module, and the sixth fixed seat 2h is used to clamp the front control arm of the second chassis front module. The second chassis front module is a chassis front module placed between the bottom support mechanism 2 and the middle support mechanism 3.

[0099] Optionally, there can be multiple fourth fixing seats 2f, multiple fifth fixing seats 2g, and multiple sixth fixing seats 2h. Multiple fourth fixing seats 2f are symmetrically arranged about the bottom support frame 22, multiple fifth fixing seats 2g are symmetrically arranged about the bottom support frame 22, and multiple sixth fixing seats 2h are symmetrically arranged about the bottom support frame 22.

[0100] In this way, the second chassis front module can be placed on the bottom support frame 22, and the second chassis front module can be limited by the fourth fixed seat 2f, the fifth fixed seat 2g and the sixth fixed seat 2h to prevent the second chassis front module from moving.

[0101] Optionally, the upper surface of the bottom support frame 22 may have multiple protective pads 1a.

[0102] This prevents the bottom support frame 22 from directly contacting the front module of the second chassis, thereby avoiding scratching the front module of the second chassis.

[0103] III. Mid-level support structure 3

[0104] The middle support mechanism 3 is a component in the front module fixture of the automobile chassis used to snap onto the third front module of the chassis.

[0105] like Figure 1 As shown, the middle support mechanism 3 includes a first middle support frame 31, a first pneumatic spring 32, a second middle support frame 33, and a second pneumatic spring 34. The first middle support frame 31 is hinged to the first hinge shaft support 131a. One end of the first pneumatic spring 32 is hinged to the first spring connecting seat 125a, and the other end is hinged to the first middle support frame 31. The second middle support frame 33 is hinged to the third hinge shaft support 133a. One end of the second pneumatic spring 34 is hinged to the third spring connecting seat 126a, and the other end is hinged to the second middle support frame 33.

[0106] Specifically, when the first intermediate support frame 31 is parallel to the horizontal frame 11, the first gas spring 32 is in a first compressed state; when the second intermediate support frame 33 is parallel to the horizontal frame 11, the second gas spring 34 is in a first compressed state; when the first intermediate support frame 31 is perpendicular to the horizontal frame 11, the first gas spring 32 is in a second compressed state; and when the second intermediate support frame 33 is perpendicular to the horizontal frame 11, the second gas spring 34 is in a second compressed state. The spring thrust corresponding to the first compressed state is greater than the spring thrust corresponding to the second compressed state. The spring thrust corresponding to the first compressed state is less than half the weight of the front module of the vehicle chassis, and the spring thrust corresponding to the second compressed state is greater than the weight of the first intermediate support frame 31 and the second intermediate support frame 33.

[0107] Optionally, such as Figure 4 As shown, the middle layer support mechanism 3 also includes a seventh fixed seat 3f, an eighth fixed seat 3g, and a ninth fixed seat 3h. The seventh fixed seat 3f, the eighth fixed seat 3g, and the ninth fixed seat 3h are all located on the upper surface of the first middle layer support frame 31 and are all connected to the first middle layer support frame 31.

[0108] The seventh fixed seat 3f is used to engage the steering gear tie rod of the third chassis front module; the eighth fixed seat 3g is used to engage the front longitudinal beam mounting bracket of the third chassis front module; and the ninth fixed seat 3h is used to engage the front control arm of the third chassis front module. The third chassis front module is a chassis front module placed between the middle support mechanism 3 and the upper support mechanism 4.

[0109] Optionally, there can be multiple seventh fixing seats 3f, eight fixing seats 3g, and ninth fixing seats 3h. Multiple seventh fixing seats 3f are symmetrically arranged about the bottom support frame 22, multiple eighth fixing seats 3g are symmetrically arranged about the bottom support frame 22, and multiple ninth fixing seats 3h are symmetrically arranged about the bottom support frame 22.

[0110] In this way, the third chassis front module can be placed on the first middle layer support frame 31 and the second middle layer support frame 33, and the third chassis front module can be limited by the seventh fixed seat 3f, the eighth fixed seat 3g and the ninth fixed seat 3h to prevent the third chassis front module from moving.

[0111] Optionally, the upper surfaces of the first intermediate support frame 31 and the second intermediate support frame 33 may have multiple protective pads 1a.

[0112] This prevents the first middle layer support frame 31 and the second middle layer support frame 33 from directly contacting the third chassis front module, thereby avoiding scratching the third chassis front module.

[0113] IV. Upper Support Structure 4

[0114] The upper support mechanism 4 is a component in the front module fixture of the automobile chassis used to snap onto the fourth front module of the chassis.

[0115] like Figure 1 As shown, the upper support mechanism 4 includes a first upper support frame 41, a third pneumatic spring 42, a second upper support frame 43, and a fourth pneumatic spring 44. The first upper support frame 41 is hinged to the second hinge shaft support 132a. One end of the third pneumatic spring 42 is hinged to the second spring connecting seat 125b, and the other end is hinged to the first upper support frame 41. The second upper support frame 43 is hinged to the fourth hinge shaft support 134a. One end of the fourth pneumatic spring 44 is hinged to the fourth spring connecting seat 126b, and the other end is hinged to the second upper support frame 43.

[0116] Specifically, when the first upper support frame 41 is parallel to the horizontal frame 11, the third gas spring 42 is in the third compression state; when the second upper support frame 43 is parallel to the horizontal frame 11, the fourth gas spring 44 is in the third compression state; when the first upper support frame 41 is perpendicular to the horizontal frame 11, the third gas spring 42 is in the fourth compression state; and when the second upper support frame 43 is perpendicular to the horizontal frame 11, the fourth gas spring 44 is in the fourth compression state. The spring thrust corresponding to the third compression state is greater than the spring thrust corresponding to the fourth compression state. The spring thrust corresponding to the third compression state is less than half the weight of the front module of the vehicle chassis, and the spring thrust corresponding to the fourth compression state is greater than the weight of the first upper support frame 41 and the second upper support frame 43.

[0117] Optionally, such as Figure 4 As shown, the upper support mechanism 4 also includes a tenth fixed seat 4f, an eleventh fixed seat 4g and a twelfth fixed seat 4h. The tenth fixed seat 4f, the eleventh fixed seat 4g and the twelfth fixed seat 4h are all located on the upper surface of the first upper support frame 41 and are all connected to the first upper support frame 41.

[0118] Among them, the tenth fixed seat 4f is used to snap on the steering gear tie rod of the fourth chassis front module, the eleventh fixed seat 4g is used to snap on the front longitudinal beam mounting bracket of the fourth chassis front module, and the twelfth fixed seat 4h is used to snap on the front control arm of the fourth chassis front module. The fourth chassis front module is a chassis front module placed between the upper support mechanism 4 and the equipment top cover 5.

[0119] Optionally, the number of the tenth fixing seat 4f, the eleventh fixing seat 4g and the twelfth fixing seat 4h can all be multiple, with multiple tenth fixing seats 4f arranged symmetrically about the bottom support frame 22, multiple eleventh fixing seats 4g arranged symmetrically about the bottom support frame 22, and multiple twelfth fixing seats 4h arranged symmetrically about the bottom support frame 22.

[0120] In this way, the fourth chassis front module can be placed on the first upper support frame 41 and the second upper support frame 43, and the fourth chassis front module can be limited by the tenth fixed seat 4f, the eleventh fixed seat 4g and the twelfth fixed seat 4h to prevent the fourth chassis front module from moving.

[0121] Optionally, the upper surfaces of the first upper support frame 41 and the second upper support frame 43 may have multiple protective pads 1a.

[0122] In this way, the first upper support frame 41 and the second upper support frame 43 can directly contact the fourth chassis front module, thereby avoiding scratching the fourth chassis front module.

[0123] Optionally, the first chassis front module, the second chassis front module, the third chassis front module, and the second chassis front module can be chassis front modules of different models.

[0124] V. Equipment Top Cover 5

[0125] The top cover 5 is a component in the front module fixture of the automobile chassis used to hold the fourth front module of the chassis that has fallen off.

[0126] like Figure 1 As shown, the top cover 5 of the device is a rectangular frame and is located between the second vertical beam 122 and the fourth vertical beam 124. The first edge 5a of the top cover 5 is rotatably connected to the second vertical beam 122, and the second edge 5b of the top cover 5 is in contact with the surface of the fourth vertical beam 124 near the second vertical beam 122 and is rotatably connected to the fourth vertical beam 124. The rotation axis of the top cover 5 and the second vertical beam 122 and the fourth vertical beam 124 is coaxial. The axis is located on the side of the first baffle 124n away from the third vertical beam 123 and is higher than the first baffle 124n. When the top cover 5 is in contact with the top surface of the first baffle 124n, the top cover 5 is parallel to the horizontal frame 11.

[0127] Optionally, the front module mounting for the vehicle chassis may also include multiple straps 8 and multiple strap fixing seats 7.

[0128] like Figure 5 As shown, one strap fixing seat 7 is located on the upper surface of the second crossbeam 132 and connected to the second crossbeam 132, and the other strap fixing seat 7 is located on the upper surface of the fourth crossbeam 134 and connected to the fourth crossbeam 134. One end of each of the multiple straps 8 is fixedly connected to the top cover 5 of the equipment, and the other end is detachably connected to the strap fixing seat 7.

[0129] In this way, after the fourth chassis front module is placed, the other ends of the multiple straps 8 can be connected to the strap fixing seat 7, thereby preventing the fourth chassis front module from falling off the upper support mechanism 4.

[0130] The following sections will introduce some optional structural features of the front module of the automobile chassis.

[0131] Structural feature 1: The front module mounting of the automobile chassis may also include anti-collision pad assembly 6.

[0132] like Figure 4As shown, the anti-collision pad group 6 includes a first anti-collision pad 61, a second anti-collision pad 62, a third anti-collision pad 63, and a fourth anti-collision pad 64. The first anti-collision pad 61 is connected to the end of the first vertical beam 121 away from the horizontal frame 11, the second anti-collision pad 62 is connected to the end of the second vertical beam 122 away from the horizontal frame 11, the third anti-collision pad 63 is connected to the end of the third vertical beam 123 away from the horizontal frame 11, and the fourth anti-collision pad 64 is connected to the end of the fourth vertical beam 124 away from the horizontal frame 11.

[0133] This prevents and improves the safety of using front-mounted modules on the vehicle chassis.

[0134] Structural Feature 2: The outer frame 1 may include multiple reinforcing ribs.

[0135] like Figure 4 As shown, the outer frame 1 also includes a first reinforcing rib 15, a second reinforcing rib 16, a third reinforcing rib 17, and a fourth reinforcing rib 18. The first reinforcing rib 15, the second reinforcing rib 16, the third reinforcing rib 17, and the fourth reinforcing rib 18 are all right-angled triangular plates. The two right-angled sides of the first reinforcing rib 15 are connected to the first vertical beam 121 and the horizontal frame 11, respectively. The two right-angled sides of the second reinforcing rib 16 are connected to the second vertical beam 122 and the horizontal frame 11, respectively. The two right-angled sides of the third reinforcing rib 17 are connected to the third vertical beam 123 and the horizontal frame 11, respectively. The two right-angled sides of the fourth reinforcing rib 18 are connected to the fourth vertical beam 124 and the horizontal frame 11, respectively.

[0136] Optionally, such as Figure 4 As shown, the two right-angled sides of the first reinforcing rib 15 are connected to the surface of the first vertical beam 121 near the fourth vertical beam 124 and the upper surface of the horizontal frame 11, respectively. The two right-angled sides of the second reinforcing rib 16 are connected to the surface of the second vertical beam 122 near the third vertical beam 123 and the upper surface of the horizontal frame 11, respectively. The two right-angled sides of the third reinforcing rib 17 are connected to the surface of the third vertical beam 123 near the second vertical beam 122 and the upper surface of the horizontal frame 11, respectively. The two right-angled sides of the fourth reinforcing rib 18 are connected to the surface of the fourth vertical beam 124 near the first vertical beam 121 and the upper surface of the horizontal frame 11, respectively.

[0137] This can improve the mechanical strength of the outer frame 1.

[0138] Structural feature three: The front module fixture of the automobile chassis may include multiple clamping blocks 1b.

[0139] like Figure 5As shown, clamping block 1b is located on the surface of the bottom support frame 22 near the horizontal frame 11 and is connected to the bottom support frame 22. Clamping block 1b is located on the surface of the first middle support frame 31 and the second middle support frame 33 near the horizontal frame 11 and is connected to the first middle support frame 31 and the second middle support frame 33. Clamping block 1b is located on the surface of the first upper support frame 41 and the second upper support frame 43 near the horizontal frame 11 and is connected to the first middle support frame 31 and the second middle support frame 33. Clamping block 1b is located on the surface of the top cover 5 of the fixture near the first vertical beam 121 and is connected to the top cover 5 of the fixture.

[0140] In this way, the clamping block 1b contacts the front module of the car chassis placed below it, which can prevent the front module of the car chassis from moving upward.

[0141] This application provides a front module mounting fixture for an automobile chassis. The bottom support mechanism 2 of the front module is hinged to a horizontal frame 11. The middle support mechanism 3 includes a first middle support frame 31, a first gas spring 32, a second middle support frame 33, and a second gas spring 34. Both the first and second middle support frames 31 and 33 are hinged to a crossbeam assembly 13. The two ends of the first gas spring 32 are respectively hinged to the first middle support frame 31 and the crossbeam assembly 13. The second gas spring 34... The upper support mechanism 4, consisting of a first upper support frame 41, a third gas spring 42, a second upper support frame 43, and a fourth gas spring 44, is hinged at both ends to the second middle support frame 33 and the crossbeam assembly 13, respectively. Both the first and second upper support frames 41 and 43 are hinged to the crossbeam assembly 13. The two ends of the third gas spring 42 are hinged to the first upper support frame 41 and the crossbeam assembly 13, respectively, and the two ends of the fourth gas spring 44 are hinged to the second upper support frame 43 and the crossbeam assembly 13, respectively. This allows four front chassis modules to be placed sequentially on top of the horizontal frame 11, the bottom support mechanism 2, the middle support mechanism 3, and the upper support mechanism 4, eliminating the need for multiple front chassis modules to be laid flat and reducing the assembly area. Meanwhile, when the technician removes the front chassis module placed on the top, the support frame supporting the front chassis module will change from a state parallel to the horizontal frame 11 to a state perpendicular to the horizontal frame 11 under the action of the gas spring. Therefore, the technician can directly grab the front chassis module placed on the next layer of support frame, thereby improving the convenience of the technician to grab the front chassis module and thus improving the assembly efficiency.

[0142] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
