Description

Technical Field

[0001] The present application belongs to the field of vehicle technology, and specifically relates to a vehicle. Background Art

[0002] Existing vehicles are equipped with a parking brake device, which is located between the driver and passenger seats and connected to the vehicle body via a fixed structure. The driver pulls the parking brake handle to park the vehicle, keeping it in the parked position and preventing it from moving. However, when the parking brake is engaged, the top of the existing parking brake handle is higher than the seat support surface, making it impossible for the driver to lie flat on the driver or passenger seat to rest. Furthermore, the parking brake handle occupies too much space for passengers to move around in the vehicle, making it easy for the driver to bump into the parking brake device while moving around in the vehicle.

[0003] There is a parking brake device that includes a base, a wiring disk, a handle that rotates relative to the base, and a locking structure. The wiring disk is rotated by rotating the handle to lock with the locking structure. When the locking structure locks the wiring disk, the vehicle enters the parking brake state. In the parking brake state of the vehicle, the handle and the wiring disk can be unlocked by an unlocking switch arranged above the base, and the handle can be rotated alone to be laid flat. The fixed structure installed in the parking brake device cannot cooperate with the wiring disk and the base, resulting in that after the handle is laid flat, the unlocking switch is still higher than the supporting surface of the seat, and the driver still cannot lie flat on the driver's seat or the passenger seat to rest.

When the vehicle is in the parking brake state, the top of the parking brake device can be made not higher than the supporting surface of the seat, so that the driver can lie flat on the seat, avoid interference from the parking brake device, and ensure the driver's rest. By providing the sinking groove 2, a special accommodation space is provided for the parking brake device, reducing the space occupied by the parking brake device for people in the vehicle to move around, and improving the space utilization rate in the vehicle. At the same time, the setting of the sinking groove 2 provides protection for the parking brake device to avoid external impact and damage. In one embodiment, the setting of the sinking groove 2 provides a movable space for the handle of the parking brake device, avoiding hard contact between the handle and the fixed structure 1, and improving the service life of the parking brake device. In addition, by providing the sinking groove 2, a space for inspection and maintenance of the parking brake device is provided, which facilitates the installation and maintenance of the parking brake device during use.

[0044] Implementation method 1: Figure 1 、 Figure 2 、 Figure 3 As shown, the sinking groove 2 includes a mounting groove 21 and an avoidance groove 22. The avoidance groove 22 is recessed relative to the mounting groove 21 to avoid the parking brake device in the parking brake state. The mounting groove 21 is used to install the parking brake device, and the installation positioning of the parking brake device is achieved through the mounting groove 21. Figure 1 As shown, the avoidance groove 22 is concave relative to the installation groove 21. During the manufacturing process, the bottom surface of the avoidance groove 22 is concave to the bottom surface of the sinking groove 2. The side surface of the avoidance groove 22 ( Figure 1 The side surface located above as shown in FIG is recessed in the rear side surface of the sinking groove 2 (the side surface located behind the parking brake device) to form an avoidance side surface 221.

[0045] The provision of the avoidance groove 22 provides a clearance space for the parking brake device, preventing any portion of the lower groove 2 from interfering with the parking brake device entering the parking brake state. Furthermore, the provision of the avoidance groove 22 can effectively reduce the length of the lower groove 2, thereby improving the utilization of the space inside the vehicle and achieving a compact layout.

By increasing the length of the groove, the parking brake is secured to the front end of the groove, extending the distance between the parking brake and the rear side of the groove (located at the rear of the vehicle) to provide clearance.

[0048] In the first embodiment, the setting mode of the fixing structure 1 can be any one of the following embodiments:

[0049] Example 1: Figure 1 、 Figure 2 、 Figure 3 As shown, the fixing structure 1 includes a mounting portion 11 and a fixing portion 12. The fixing portion 12 is provided with a positioning groove 121 facing opposite to the opening of the sinking groove 2. The mounting portion 11 and the fixing portion 12 are formed separately.

The first avoidance side 111 is connected to the second avoidance side 122.

[0050] By providing the fixing portion 12 with a positioning groove 121, the connection between the fixing structure 1 and the vehicle body is facilitated, the positioning accuracy of the fixing portion 12 during installation is improved, and the deviation and error during installation are reduced. The provision of the positioning groove 121 increases the connection area between the fixing portion 12 and the vehicle body, making the fixing portion 12 more firmly fixed to the vehicle body. The mounting portion 11 has a first avoidance side 111, and the first avoidance side 111 is located behind the parking brake device, which can effectively avoid the rear part of the parking brake device. By providing the mounting portion 11 and the fixing portion 12 as separate moldings, the avoidance side 221 is provided to include the first avoidance side 111 located on the mounting portion 11 and the second avoidance side 122 located on the fixing portion 12, which can avoid the formation of the positioning groove 121 on the fixing structure 1 and the stress concentration on the avoidance side 221 caused by further forming the avoidance groove in the sinking groove, thereby preventing the avoidance side 221 from being subjected to shear force and causing material fatigue and fracture.

[0055] By providing the first side surface 111 and the second side surface 122 with an overlapping overlap portion 13, the overlapping overlap portion 13 can increase the contact area between the first avoidance side surface 111 and the second avoidance side surface 122, thereby enhancing the connection strength between the first avoidance side surface 111 and the second avoidance side surface 122. The overlap portion 13 can also disperse external loads, thereby improving the structural strength of the fixed structure 1. The overlap portion 13 can also be used for installation and positioning, ensuring the accuracy of the connection between the first avoidance side surface 111 and the second avoidance surface.

[0056] Specific Example 2: This specific example 2 is not shown in the figure, and the first avoidance side surface is butted with the second avoidance side surface. As an example, the first avoidance side surface and the second avoidance side surface are preferably connected by butt welding.

The first connecting surface 112 is connected to the second connecting surface 123, which further improves the connection strength between the mounting portion 11 and the fixing portion 12. By providing the overlapping portion 13, the contact area between the first connecting surface 112 and the second connecting surface 123 is increased. The overlapping portion 13 can disperse the external load and improve the structural strength of the fixed structure 1.

[0059] As a preferred example in this specific example, Figure 1 As shown, the sinking groove 2 is provided with a reinforcement protrusion 24 between the fastening groove 23 and the avoidance groove 22 , and the reinforcement protrusion 24 extends toward the parking brake device.

[0060] By providing a reinforcement protrusion 24 between the fastening groove 23 and the escape groove 22, the structural strength of the fixing structure 1 is enhanced, thereby increasing the service life of the fixing structure 1. The reinforcement protrusion 24 is located between the fastening groove 23 and the escape groove 22, thereby strengthening the connection strength between the fastening groove 23 and the escape groove 22, thereby preventing damage caused by insufficient strength of the connection. By providing the reinforcement protrusion 24 extending toward the parking brake device, the compressive strength of the sinking groove is improved, which can effectively withstand the weight of the parking brake device and ensure the stability of the fixing structure 1.
